Can a Nurse Practitioner Own a Med Spa in California? AB-890, the 103/104 Pathways, and the Ownership Rules

For years, a nurse practitioner in California could run a med spa only with a physician partner holding the medical side. AB-890 changed the clinical picture — but not for every NP, and not in one clean stroke. This guide separates the three questions that actually decide whether you can open the doors: what you may clinically do (your certificate), what business entity you may own (corporate practice of medicine), and who on your staff may perform which procedure (everyone else's licence). We cite the actual statute and regulation sections throughout, and where California's position is genuinely unsettled we say so rather than guess.

This is the California-specific analysis. For the national picture of NP-ownership authority state by state, see our nurse practitioner med spa ownership guide — we do not restate that 50-state survey here. And once you have decided California is your market, the operational launch sequence lives in the California NP med spa playbook.

Can an NP Own a Med Spa in California? The Direct Answer

Take the three most common situations directly:

• You are a standard NP (no AB-890 certificate). You cannot own or solely direct a med spa. You practice under standardized procedures with a physician, and a physician must hold the medical corporation. This is where most California NPs still are.
• You are a 103 NP. You have dropped standardized procedures, but you must practice inside a qualifying setting that includes at least one physician. You can be the clinical engine of a med spa; you cannot be its sole owner-director without that physician in the group.
• You are a 104 NP. You may practice independently, perform your own good-faith exams, prescribe, and treat — no physician required in the practice at all, as long as you stay inside your national certification's population focus. On the clinical question you are now equivalent to a physician for these services. On the ownership question, whether you may wholly own the entity that bills for medical aesthetic services is the part California has not cleanly resolved — and it is the part that sends careful operators to a health-care attorney before they sign a lease.

Hold those two axes — clinical authority and ownership authority — apart in your head for the rest of this article. Conflating them is the single most expensive mistake NPs make with AB-890.

What AB-890 Actually Did — and What It Did Not

Assembly Bill 890 was signed in September 2020 and amended the Nursing Practice Act, adding Business and Professions Code sections 2837.103, 2837.104, and 2837.105. Its purpose was access to care: the Legislature concluded that requiring standardized procedures and physician oversight for every experienced NP was throttling primary-care capacity in underserved parts of California. It did not write a blank check. It built a graduated, experience-gated pathway.

The Two Certificates It Created

AB-890 created two new categories, universally referred to by their code sections. A 103 NP (BPC § 2837.103) may practice without standardized procedures within specified organizational settings that include physicians. A 104 NP (BPC § 2837.104) may practice without standardized procedures outside those settings — the genuinely independent tier. Both certificates are issued by the California Board of Registered Nursing (BRN), not the Medical Board of California. That jurisdictional detail matters: your practice authority as an NP is regulated by the BRN, while much of what happens in an aesthetic practice — the good-faith exam standard, the corporate-practice rules, medical-assistant scope — is Medical Board territory. An NP-owned med spa answers to both boards at once.

What AB-890 Did Not Touch

AB-890 removed one requirement — standardized procedures and, for 104 NPs, the supervising-physician relationship. It left the rest of California's regulatory architecture standing. It did not repeal the corporate practice of medicine doctrine. It did not amend the Moscone-Knox Professional Corporation Act or the shareholder rules for medical corporations. It did not change the good-faith examination requirement, the medical-assistant scope regulations, the esthetician scope statute, or the rules on who may fire a laser. A 104 NP who assumes independence means "no rules apply" has misread the bill. Independence means the physician-supervision requirement is gone; every other requirement transfers to the NP, in full.

How SB 1451 Reshaped the Pathway in 2025

The pathway you apply under today is AB-890 as amended by Senate Bill 1451, effective January 1, 2025. SB 1451 clarified that the three full-time-equivalent years (or 4,600 hours) need not be consecutive and may be counted within the last five years, and that hours from before January 2021 and from a different population category can count. It simplified the attestation — the attesting practitioner now verifies only completion, not competence, and is legally immune. And it updated the section 2837.105 patient-disclosure rules so that written notice that the NP is not a physician is sufficient, dropping the earlier verbal mandate. If you are reading older AB-890 explainers, assume the transition-to-practice and disclosure details have moved.

The 103 NP: Practice Without Standardized Procedures, But Not Alone

The 103 NP is the on-ramp, and the great majority of AB-890 NPs are here. Section 2837.103 lets you drop standardized procedures — the written protocols that traditionally define and constrain NP practice — but only inside specific organizational settings, and only where physicians also practice. It is real added autonomy. It is not independence, and it is not ownership. The comparison below frames the two certificates before we take each apart.

The Six Qualifying Settings for a 103 NP

Section 2837.103 does not let a 103 NP drop standardized procedures anywhere. It lists the settings, and each is defined by cross-reference to another code. A 103 NP may practice without standardized procedures only within one of these, and only alongside one or more physicians and surgeons practicing in the same setting or organization:

• A clinic as defined in Health and Safety Code § 1200;
• A health facility as defined in Health and Safety Code § 1250 (with certain exemptions);
• A facility described in Chapter 2.5 of Division 2 of the Health and Safety Code;
• A medical group practice, including a professional medical corporation as defined in BPC § 2406;
• A home health agency as defined in Health and Safety Code § 1727; and
• A hospice licensed under Chapter 8.5 of Division 2 of the Health and Safety Code.

A typical aesthetic med spa is organized as a professional medical corporation or a medical group practice — the fourth item on that list. So a 103 NP can absolutely work in, and be the clinical lead of, a med spa. What the setting requirement means in plain terms is that a physician must be part of that organization. The 103 NP is not supervised in the old standardized-procedure sense, but they are not flying solo either.

What a 103 NP May and May Not Do

Inside a qualifying setting, a 103 NP may perform the good-faith examination, order and prescribe, and administer the full aesthetic menu within their certification scope — injectables, energy-device treatments, and the rest — without a written standardized procedure for each. That is a meaningful upgrade from a standard NP arrangement. What a 103 NP may not do is be the sole medical owner-director of the facility with no physician in the organization. The physician's presence in the group is the condition on which the 103 NP's drop of standardized procedures rests. Strip the physician out and a 103 NP is back to needing standardized procedures. For an NP building toward 104, working as a 103 NP in a group med spa is also how you accumulate the good-standing years — while learning the protocol-writing, compliance, and staff-supervision skills that become entirely yours later.

The 104 NP: California's First True Independent Path

The 104 certificate is the one that changes the picture. Under section 2837.104, a 104 NP may practice without standardized procedures outside the six settings — meaning solo, in a practice with no physician at all. This is the first time in California history that a nurse practitioner can run a clinical aesthetic practice with no physician in the building or on the org chart. Because the earliest 103 certificates were issued around 2023, and 104 eligibility layers additional years on top, the BRN could begin issuing 104 certificates on January 1, 2026 — which is why "2026" is the year this question suddenly matters.

The Transition-to-Practice Hours, and How They Are Documented

Every AB-890 pathway runs through the transition to practice defined in section 2837.103: a minimum of three full-time-equivalent years of direct patient care or 4,600 hours (see the SB 1451 flexibility notes above). The transition is documented by an attestation from a qualifying practitioner confirming completion — nothing more. Keep your own contemporaneous record of hours and settings; the attestation confirms completion, but you are the one who has to reconstruct the underlying practice history if the BRN asks.

The Three-Year Good-Standing Requirement — Read It Carefully

This is the requirement most often stated wrong, so here is the statutory language. Section 2837.104 requires that you meet all of the 103 NP requirements and have "practiced as a nurse practitioner in good standing for at least three years, not inclusive of the transition to practice required pursuant to… Section 2837.103." Read literally, that is three years of NP practice in good standing on top of the transition-to-practice period — not, in so many words, three years holding a 103 certificate. The popular shorthand "three years as a 103 NP" is a reasonable practical approximation of the timeline, but it is not a byte-for-byte restatement of the statute, and if your exact eligibility date turns on it, that is a question for the BRN and a health-care attorney, not for a blog. The BRN may also shorten the requirement for some applicants holding a Doctor of Nursing Practice (DNP) degree. The safe planning number for most NPs remains roughly six years total: the transition to practice plus at least three more good-standing years.

What the BRN Requires to Certify a 104 NP

Both certificates are issued by the California Board of Registered Nursing, and the BRN's application requirements have evolved since AB-890's regulations were finalized — always confirm the current forms directly with the Board. In general, a 104 applicant must hold an active California RN license and NP certification in good standing, hold a master's or doctoral degree in nursing or a related clinical field, satisfy all of the 103 requirements (including the transition-to-practice attestation and a national NP board certification from an accredited body such as the ANCC or AANP), and document the additional good-standing practice years. Current BRN information and forms live at rn.ca.gov — Nurse Practitioner Practice. Do not schedule an opening date before the certificate is physically in hand: operating as a 104 NP on the strength of eligibility, before the BRN has issued the certificate, is a violation regardless of how experienced you are.

Where a 104 NP May Practice Independently

The 104 NP's independence is bounded by the population focus of their national certification, and this is a hard limit, not a formality. A Family NP (FNP) covers patients across the lifespan and is the most flexible certification for a cosmetic practice. An Adult-Gerontology NP (AGNP) covers adults and geriatric patients — appropriate for essentially all adult cosmetic clientele, but not minors. A Pediatric NP cannot treat the adult cosmetic population; a Psychiatric-Mental Health NP (PMHNP), Women's Health NP (WHNP), or Neonatal NP has a population focus that does not encompass general aesthetic medicine. A PMHNP who injects Botox is practicing outside their certification's scope even with a 104 certificate — the independence attaches to the population you are certified for, not to all of medicine. The scope limit also drives your malpractice coverage: confirm in writing that your carrier covers your exact procedures and patient population, because a claim arising outside your certification scope is a claim your insurer may decline. For the medical-director dimension specifically, see our California med spa medical director requirements guide.

Ownership vs. Practice: The Distinction That Trips Up Every NP

Here is the pivot the quick answer flagged. AB-890 is a practice statute — it governs what an NP may clinically do. It is not an ownership statute. The question of who may own the business entity that renders and bills for medical aesthetic services is governed by an entirely separate body of law that AB-890 never touched. A 104 NP can have flawless clinical independence and still get the ownership structure wrong. This is the section to read twice, and the section on which to spend money on a California health-care attorney before you form an entity.

The Corporate Practice of Medicine Doctrine and the Medical Corporation

California's corporate practice of medicine (CPOM) doctrine holds that a corporation cannot practice medicine or employ physicians to deliver medical care; medical services must be rendered through a properly licensed professional entity controlled by licensed professionals. Aesthetic procedures like injectables and laser are the practice of medicine. So the med spa's medical services generally must flow through a professional medical corporation (BPC § 2406) or an equivalent licensed structure — not an ordinary LLC or C-corp. AB-890 gave a 104 NP the right to practice without a physician; it did not rewrite which entity type may hold a medical practice.

The Moscone-Knox Act and Who May Hold Shares

The Moscone-Knox Professional Corporation Act (Corporations Code §§ 13400–13410) governs professional corporations, and Corporations Code § 13401.5 lists the non-physician licensees who may hold shares in a professional medical corporation — registered nurses (which includes NPs), physician assistants, psychologists, podiatrists, and others. The catch is the ceiling: those non-physician shareholders are capped at 49 percent in the aggregate, and they may not outnumber the physician shareholders. So in a medical-corporation structure, an NP can hold shares — but not a controlling 100 percent stake. AB-890 did not lift the Moscone-Knox cap. If you intend to bring on other clinicians or scale, and you are in a medical-corporation structure, the 51/49 split still binds you.

The Nursing Corporation Route — and Its Ceiling

The natural follow-up: can a 104 NP simply form a professional nursing corporation (BPC §§ 2775–2781) and own 100 percent of it? A nursing corporation may be wholly owned by nurses, which is attractive. But a nursing corporation is expressly not authorized to practice medicine, and whether the aesthetic services a med spa sells fall inside "nursing" or spill into "medicine" — especially prescriptive procedures and energy devices — is exactly the line California has not cleanly drawn for NP-owned aesthetic practices. Some attorneys structure a 104 NP med spa as a nursing corporation on the theory that a 104 NP's independent authority now supports it; others remain cautious that a regulator could view specific procedures as the practice of medicine requiring a medical corporation. The Board has not issued definitive public guidance resolving this for med spas. That is the honest state of the law as of this writing: the clinical independence is clear; the entity that may wholly own an NP-led aesthetic practice is genuinely unsettled. Treat any confident, one-size answer — in either direction — with suspicion, and get a written opinion for your specific menu. Our companion guide, who can own a med spa in California, walks the CPOM structures in more depth.

What SB 351 Changed on January 1, 2026

The ownership question got more scrutinized in 2026, not less. Senate Bill 351, effective January 1, 2026, codified and strengthened California's corporate-practice doctrine and placed new limits on private-equity groups and hedge funds — and the management-services organizations (MSOs) they use — interfering with clinical judgment or exercising control over billing, coding, equipment selection, and clinical-staff oversight. Many med spas run on an MSO-plus-professional-entity model, and SB 351 sharpens the line between legitimate administrative support and unlawful control of a medical practice. For an NP owner, the takeaway is that the regulatory climate around who really controls a clinical practice is tightening; a structure that looks clever on paper but hands practice control to a non-licensed management entity is now squarely in the enforcement conversation.

Does a 104 NP Med Spa Still Need a Physician or Medical Director?

For a qualifying 104 NP practicing strictly within their certification's population focus, the answer on the clinical question is no — that is the entire point of the 104 certificate. The 104 NP is the prescriber, performs the good-faith exam, and directs care without a supervising physician. There is no statutory requirement that a 104 NP retain a medical director for services within their scope.

Three practical qualifiers, though. First, scope-boundary services: if you offer anything that reaches beyond your NP certification's population focus or beyond nurse-practitioner scope, that service needs an appropriately licensed provider — a 104 NP certificate does not stretch your clinical scope, only your independence within it. Second, the ownership structure discussed above may still pull a physician into the entity even when clinical supervision is not required — that is a corporate-law reason, not a supervision reason, and the two are easy to conflate. Third, continuity risk: a single-NP practice has a single point of failure, so many 104 owners keep a backup medical director agreement or physician relationship as contingency even though day-to-day operation does not require it. Since the written protocol infrastructure is now entirely your responsibility, many NP owners start from the full 62-protocol SOP library and tailor it to their menu rather than drafting every procedure from a blank page.

Licence-by-Licence: Who on Your Staff May Do What

An NP owner does not treat every patient personally. The staff you hire each carry their own scope, set by their own board, and AB-890 does nothing for any of them — it amends only the nurse-practitioner sections of the Nursing Practice Act. Get this wrong and the citation lands on you as owner. Here is each role, with the direct verdicts on the three questions that matter in an aesthetic practice: may they inject, may they run an energy device, and may they perform the good-faith exam.

Physician (MD/DO)

A physician may do everything: perform the good-faith exam, prescribe, inject neurotoxins and fillers, operate lasers and energy devices, and supervise others. In a 104 NP-owned practice a physician is not required for services within the NP's scope, but a physician is the appropriate provider for anything that reaches beyond nurse-practitioner scope. On the ownership side, a physician is also the shareholder who can hold the controlling 51 percent of a professional medical corporation — which is why physicians still appear in NP-adjacent structures even when clinical supervision is not required.

Physician Assistant (PA)

A PA may perform the good-faith exam, prescribe, inject, and operate energy devices — but a PA practices under a practice agreement with a supervising physician. A PA does not have an AB-890-style independent path. In a 104 NP practice with no physician, a PA has no supervising physician, which is a structural problem: the PA's authority is derived from physician supervision that the independent NP model removes. If you plan to employ PAs, you generally need a physician in the structure for them, separate from your own NP independence.

Registered Nurse (RN)

An RN may inject neurotoxins and fillers and operate lasers and energy devices — but only after a qualified prescriber (physician, NP, or PA) has performed a good-faith exam and issued a patient-specific order, and under appropriate delegation. An RN may not perform the good-faith exam and may not independently generate the treatment order. In a 104 NP practice, you (the NP) perform the exam and write the order; the RN carries out the treatment. That division — prescriber examines and orders, RN administers — is the backbone of a compliant NP-led med spa.

Licensed Vocational Nurse (LVN)

An LVN's aesthetic role is far narrower and is a frequent enforcement trap. California does not treat cosmetic injectables or laser as within LVN independent scope the way it does for RNs; LVNs are not permitted to perform aesthetic injectable or laser procedures in the med spa context even under supervision. Do not staff your injection or laser line with LVNs. An LVN cannot perform the good-faith exam.

Esthetician

Estheticians are licensed by the Board of Barbering and Cosmetology under BPC § 7316, and their scope is surface-of-the-skin cosmetic work: facials, waxing, and superficial exfoliation with over-the-counter products. Estheticians may not inject, may not operate medical lasers or IPL, may not perform the good-faith exam, and — per repeated Board enforcement — may not perform microneedling that penetrates living tissue or medical-depth chemical peels. The governing line is simple: if a treatment penetrates or removes living tissue, it is medicine and outside esthetician scope. Allowing an esthetician to fire a laser is illegal and exposes the owner directly.

Medical Assistant and Unlicensed Staff

Medical assistants are unlicensed and the most misused role in med spas. Under the Medical Board's regulations (16 CCR §§ 1366 et seq.), an MA may perform certain technical support tasks and may administer some medications by intradermal, subcutaneous, or intramuscular injection under specific supervision — but the Board has stated an MA may not inject Botox or dermal filler and may not operate lasers or IPL to remove hair or treat skin. MAs cannot perform the good-faith exam. Purely unlicensed staff (front desk, coordinators) may not perform any clinical procedure at all. Letting a medical assistant inject is, per the Medical Board, one of the most common citations it issues — and in an NP-owned practice, the NP owner absorbs the liability.

Procedure-by-Procedure: What Changes for an NP Owner

AB-890 changes the same one thing for every procedure: whether you need a physician to authorize it. It changes nothing about whether the procedure needs a good-faith exam, a prescription, or an appropriately licensed hand to perform it. Here is the aesthetic menu, procedure by procedure, from the vantage point of a qualifying 104 NP owner.

Neurotoxins and Dermal Fillers

These are prescription treatments and the core of most med spas. As a qualifying 104 NP within your certification's population focus, you may perform the good-faith exam, prescribe, and inject — no physician co-sign. You may also delegate the injection to an RN after you have examined the patient and written a patient-specific order. What has not changed: the exam still has to happen and be documented, and the injector must be a physician, NP, PA, or a properly ordered RN — never an LVN, MA, or esthetician. For the injector-eligibility rules in detail, see who can inject Botox in California.

Energy Devices and Lasers

California treats laser and IPL procedures as the practice of medicine. A 104 NP may perform them and may order and delegate them to an RN after a good-faith exam and patient-specific order. The device cannot be operated by an esthetician, cosmetologist, LVN, or medical assistant — a common and heavily enforced violation. AB-890 removes the physician-authorization layer for a 104 NP; it does not widen the set of licences that may fire the device.

Chemical Peels

Depth is the dividing line. Superficial peels using over-the-counter-strength products can fall within esthetician scope; medical-depth peels using physician-strength agents are medical procedures requiring a qualified clinician and a good-faith exam. As a 104 NP you may perform and order medical peels within your scope. Do not let the esthetician on staff drift from a superficial peel into medical-depth territory — the Board draws the line at penetration of living tissue.

Microneedling

California regulators have been explicit that microneedling and dermarolling which penetrate living tissue are outside esthetician scope and are being actively enforced against. In a med spa, microneedling belongs to clinical staff. A 104 NP may perform it and order it for delegation; an esthetician performing medical-depth microneedling is practicing outside their licence, and the owner is exposed.

IV Therapy

IV hydration and nutrient therapy involve prescription components and require a good-faith exam and a prescriber's order. A 104 NP may perform the exam, prescribe, and order IV therapy for RN administration. Standing orders that skip an individualized prescriber assessment are exactly the pattern regulators have flagged — the order must connect to a real, documented exam of that patient.

GLP-1 and Weight-Loss Prescribing

GLP-1 medications such as semaglutide and tirzepatide are prescription drugs, and a qualifying 104 NP may prescribe them independently within their scope — one of the clearest wins of the 104 certificate, since it removes the need for a physician to sign the GFE behind each weight-loss prescription. But 2026 enforcement here is aggressive on multiple fronts: bulk-stocking compounded GLP-1s without patient-specific justification, sham or skipped good-faith exams in telehealth models, and RN administration under standing orders lacking an individualized prescriber assessment are all named enforcement targets. Independence raises the stakes: with no physician in the loop, the documentation discipline is entirely yours. Our California med spa compliance checklist covers the weight-loss documentation trail in practical detail.

The Good-Faith Examination: The Requirement Enforcement Cares About Most

If you take one operational rule from this article, take this one. Before any prescription aesthetic treatment — neurotoxin, filler, laser, medical peel, microneedling, IV therapy, GLP-1 — California requires a good-faith examination (GFE) of the patient by a licensed prescriber, and a resulting patient-specific treatment order. The GFE requirement is rooted in Medical Board standards (and reinforced by 2026 changes under SB 351 and BPC § 2242 enforcement); it is not optional, and it is the single most common thread in med spa enforcement actions.

What AB-890 changes is who may sign it. A good-faith exam must be performed by a physician, NP, or PA — never an RN, LVN, medical assistant, or esthetician. In a physician-supervised model, a physician (or the NP/PA under the physician's structure) signs. For a qualifying 104 NP, you sign your own — within your certification's population focus, with no physician co-signature required. That is the practical heart of what independence buys you: you are the prescriber of record. The exam may be conducted in person or, where clinically appropriate and compliant, via telehealth — but a "GFE" that is a rubber stamp on an intake form, or a standing order untethered to an actual assessment of that specific patient, is precisely what regulators treat as no exam at all.

Documentation a 104 NP Owner Must Be Able to Produce

When a physician holds the medical side, the physician owns much of the compliance paper trail. As a 104 NP owner, that entire file is yours. If the BRN, the Medical Board, or a plaintiff's attorney comes asking, these are the documents you must be able to produce on demand:

• Your BRN 104 certificate and current NP certification, plus RN licensure — proof you actually hold the authority you are operating under.
• Written treatment protocols for every procedure on your menu. Independence transfers, rather than removes, the obligation to have a documented, defensible protocol for each service.
• Good-faith examination records tied to each patient, with your assessment and the resulting patient-specific order — not a template attached to an intake form.
• Delegation and standardized-procedure documentation for anything an RN performs on your order, showing the exam-then-order-then-delegate chain.
• Staff licensure and scope records — a current file on every clinical hand proving they are operating inside their own licence.
• Corporate structure documents — your professional entity formation, shareholder records, and any MSO or management agreement, which SB 351 makes more consequential in 2026.
• Malpractice coverage that names your specific procedures and patient population, and adverse-event and consent records for treatments performed.

Build the file before you open, not after the first complaint.

What Actually Gets an NP-Owned Med Spa in Trouble in California

Enforcement in California is not evenly distributed — it clusters around a handful of patterns, and an NP owner should know them cold because the liability now runs to you. The relevant boards are the Medical Board of California (good-faith exams, corporate practice, medical-assistant scope, laser as practice of medicine), the Board of Registered Nursing (your NP certificate and scope), the Board of Barbering and Cosmetology (estheticians drifting into medical procedures), the Board of Pharmacy (compounded GLP-1s and drug handling), and increasingly the Attorney General under SB 351 for corporate-control violations. The recurring failure modes:

• Skipped or sham good-faith exams — the most cited pattern, and worse in high-volume or telehealth GLP-1 models. A standing order untethered to an individualized assessment is treated as no exam.
• Wrong hands on the procedure — medical assistants injecting, estheticians firing lasers or doing medical-depth microneedling, LVNs on the injectable line. The Medical Board calls MA-injection one of its most common citations.
• Practicing outside certification scope — a PMHNP or other non-adult-population NP treating cosmetic patients, even with a 104 certificate.
• Operating before the certificate issues — running independently on eligibility rather than an issued 104 certificate.
• Structure that hands practice control to a non-licensed entity — an MSO or investor exercising the kind of clinical or operational control SB 351 now expressly prohibits.
• Bulk-stocked compounded drugs — holding compounded semaglutide or tirzepatide as retail inventory without patient-specific 503A justification.

Every one of these is a documentation-and-discipline problem, not a bad-luck problem. The NP-owned med spas that stay out of trouble are the ones whose exam records, delegation paper, and staff-scope files would survive a records request on any given Tuesday.

Opening the Doors: A Practical Sequence for an NP

Assuming you are a qualifying (or soon-to-qualify) NP set on California, here is the order operations actually happen in — designed so you never commit money to a step that a later step could invalidate:

1. Confirm your certificate status in writing. Hold the issued 103 or 104 certificate — or a realistic, BRN-confirmed timeline — before anything else. Do not sign a lease against an eligibility guess.
2. Confirm your certification covers your intended menu. FNP or AGNP for a general adult cosmetic practice; verify your population focus against every service you plan to offer.
3. Get a California health-care attorney to design the entity. This is where the ownership-vs-practice question gets resolved for your specific facts — medical corporation vs nursing corporation, any MSO, and SB 351 compliance. Do this before you form anything.
4. Line up malpractice coverage that names your procedures and patient population, and confirm it in writing.
5. Build the clinical infrastructure — good-faith exam workflow, written protocols for every procedure, delegation and standardized-procedure documents for RN-performed services, and consent forms.
6. Hire to scope. Map each role to what its licence permits before the first hire touches a patient; keep a licensure file on each.
7. Confirm device, drug, and facility requirements — laser registration where applicable, compliant drug sourcing and handling, and any local permits.
8. Open — and keep the file current. Compliance is a maintained state, not a launch checklist.

The full operational build-out, with California-specific detail, lives in the California NP med spa playbook, and the running self-audit in the California med spa compliance checklist.

104 NP vs. Physician Partner: Which Path Fits You

Not every NP who wants to own a California med spa should wait for the 104 certificate. The right call depends on your timeline, your current status, and your math.

When to Pursue 104 Status

If you already hold your 103 certificate and are within a year or two of 104 eligibility, waiting often wins. Operating as a 104 NP gives you clinical control with no physician to compensate, no shared authority, and no risk of a departing partner destabilizing the practice. For an NP who has built the clinical skill and wants autonomy, 104 is the cleanest clinical structure — with the ownership-entity question resolved by counsel up front.

When to Open With a Physician Partner Now

If you are earlier in the pathway — a standard NP starting the transition to practice, or a 103 NP still years from 104 — opening now with a physician as the controlling owner may be the better near-term move. The practice operates cleanly, you build revenue and a patient base, and you can restructure toward NP ownership if and when you qualify. A physician's name can also add referral-network value in some markets. Financially, a physician medical director in California runs roughly $2,000–$6,000 per month; across the years it can take to reach 104 eligibility, that is real money a 104 NP avoids — but revenue earned by opening sooner can outweigh the director fees. Run the numbers for your own market and timeline before deciding.

Common Myths About AB-890 — Corrected

These are the beliefs that repeatedly land NPs in trouble. Each is stated as it is commonly heard, then corrected directly.

Myth: "A 104 certificate lets me own 100% of a med spa outright."

Correction: It lets you practice independently. Whether you may wholly own the entity that renders medical aesthetic services is a separate question governed by the corporate practice of medicine doctrine, the Moscone-Knox Act, and — in a medical corporation — the 49 percent non-physician cap. California has not cleanly settled the entity question for NP-owned aesthetic practices, so do not assume 100 percent ownership follows automatically from a 104 certificate.

Myth: "AB-890 helps experienced RNs too."

Correction: It does nothing for RNs, LVNs, medical assistants, or estheticians. AB-890 amends only the nurse-practitioner sections of the Nursing Practice Act. An RN, however senior, cannot own or solely direct a California med spa under AB-890.

Myth: "A 103 certificate means I can open independently."

Correction: A 103 NP must practice in a setting that includes a physician and cannot be the sole owner-director. Independence requires the 104 certificate, which layers additional good-standing years on top of the transition to practice.

Myth: "Independence means I no longer need a good-faith exam or written protocols."

Correction: Independence removes the supervising physician, not the requirements. Every patient still needs a documented good-faith exam and a patient-specific order, and every procedure still needs a written protocol. Those obligations transfer to you in full.

Myth: "My certification type doesn't matter once I'm a 104 NP."

Correction: Your national certification's population focus is a hard boundary on your independent scope. A PMHNP injecting Botox is outside scope even with a 104 certificate. FNP or AGNP is what covers an adult cosmetic practice.

Myth: "I can open the day I'm eligible to apply."

Correction: Authority comes from the issued certificate, not from eligibility. Operating independently before the BRN issues your 104 certificate is a violation, no matter how strong your application.

Summary: AB-890 and NP Med Spa Ownership

• AB-890 (BPC §§ 2837.103–2837.105) created two BRN-issued certificates: the 103 NP, which drops standardized procedures inside settings that include a physician, and the 104 NP, which allows independent practice outside those settings.
• The BRN could begin issuing 104 certificates on January 1, 2026 — the first time a California med spa can be clinically directed by an NP with no physician in the practice.
• Clinical authority and ownership authority are different questions. A 104 NP practices independently, but whether an NP may wholly own the entity rendering medical aesthetic services is governed by the corporate practice of medicine doctrine and the Moscone-Knox Act — and is genuinely unsettled. Get counsel before forming an entity.
• The pathway you apply under is AB-890 as amended by SB 1451 (2025); the corporate-practice climate was tightened by SB 351 (effective January 1, 2026).
• Your independent scope is bounded by your national certification's population focus — FNP or AGNP for an adult cosmetic practice.
• Every patient still needs a good-faith exam and a patient-specific order; a qualifying 104 NP may sign it themselves. It cannot be delegated to an RN, LVN, MA, or esthetician.
• AB-890 helps only NPs — RNs, LVNs, MAs, and estheticians gain nothing, and staffing a procedure to the wrong licence is a top enforcement pattern the NP owner absorbs.
