Can a nurse open a med spa in California?

Key Takeaways

California bars solo nurse ownership — the Corporate Practice of Medicine doctrine (CPOM) restricts medical spa ownership to licensed physicians, so RNs and NPs cannot own one outright.

MSOs offer a workaround — a Management Services Organization can own the business side while a licensed physician retains ownership of the medical practice.

NP authority is expanding, but ownership caps aren’t — starting January 1, 2026, qualifying “104” nurse practitioners gain full independent clinical practice authority, though Assembly Bill 890 leaves California’s 49% cap on non-physician ownership of a professional medical corporation untouched, so whether a 104 NP can independently direct a med spa remains unsettled.

Several licenses are required before opening — a Professional Corporation structure, a licensed medical director, cosmetology board registration (for non-invasive services), and liability insurance.

Nurses aren’t shut out — an RN can own the business side of a med spa through an MSO, and can run an adjacent venture like an IV hydration business, though in California that still needs a physician medical director and standing orders, just like a med spa.

Many nurses who spend years in direct patient care, often after building a career as an aesthetic nurse, eventually consider opening their own med spa. In California, that move runs into ownership rules that do not apply the same way in every state.

California’s Corporate Practice of Medicine doctrine limits who can legally own a medical practice, and a med spa counts as one. That means a registered nurse (RN) or nurse practitioner (NP) cannot simply lease a space and start treating patients under their own business.

This guide covers who can own and operate a med spa in California, how nurse practitioner scope of practice is changing under Assembly Bill 890, and the licenses, permits, and legal structures a med spa needs before opening. For a broader walkthrough of the process, see our guide on starting a med spa.

Can a nurse own a med spa in California?

In short, the answer is no. A registered nurse (RN) cannot open a California med spa alone.

Under California law, a medical spa is considered a medical practice, and the state’s Corporate Practice of Medicine doctrine (CPOM) restricts who can operate one. Only licensed physicians can open and operate a medical practice in California.

Ownership rules differ by state and by clinical role. Our guide on medical spa ownership breaks down physician, nurse practitioner, and MSO ownership models nationwide.

That said, nurses still have paths into med spa ownership and operation, covered below.

For nurses researching how to start a med spa as an RN, the realistic routes are owning the non-clinical business through an MSO or partnering with a physician who holds the medical entity.

Some nurses skip med spa ownership and open an adjacent wellness venture instead, such as an IV hydration business. In California, though, that’s treated as a medical service too, so it runs into the same physician-oversight rules.

Who can open and own a med spa in California?

California limits med spa ownership to three paths: licensed physicians, physician-owned practices supported by an MSO, and, under narrow conditions, nurse practitioners.

Licensed physicians

Californian laws are clear: Only state-licensed physicians or practice groups can own and operate a medical spa. 

Physician owners also carry responsibilities beyond treating patients, including:

• Overseeing all medical procedures such as Botox injections, fillers, or laser treatments
• Ensuring the staff who work there are licensed, properly trained, and compliant with state regulations
• Ensuring the med spa complies with all healthcare regulations, including patient consent, data security, and operational standards
• Upholding high standards of care, ensuring all medical spa services are performed in hygienic conditions, with clean and sanitized equipment 
• Ensuring all incidents for adverse events and deviations from standard procedures are reported

Management services organizations (MSOs)

MSOs exist to handle the business and operational side of a med spa, essentially separating a med spa business into two sides.

All the non-medical areas of a med spa are handled by the MSO, taking care of aspects like payroll, marketing, admin tasks, and accounting. While doing that, they also help med spas comply with state regulations such as: 

• HIPAA (Health Insurance Portability and Accountability Act)
• OSHA (Occupational Safety and Health Administration)
• FMLA (Family and Medical Leave Act)

What about nurse practitioners?

Currently, in California, NPs cannot own a medical spa independently.

However, things are set to change. In September 2020, a new law, Assembly Bill 890, was passed, introducing new categories of NPs. This legislation expands the scope of practice for nurses and allows them to practice independently under certain conditions without physician supervision.

Outside med spas specifically, our guide on nurse practitioner private practice covers similar independent-practice pathways for NPs nationwide.

Assembly Bill 890 went into effect in January 2023.

It means that after three years of practicing without standardized procedures in a group setting, nurse practitioners in California will be able to apply for full practice authority under the law. That’s independent clinical practice authority, though — Assembly Bill 890 doesn’t change who can own or direct a medical practice.

The conditions under which a nurse can practice are:

• Must be licensed by the California Board of Registered Nursing (BRN)
• Must hold a national certification as a nurse practitioner in their area of practice
• Must complete a transition-to-practice period: A minimum of three full-time years (or 4,600 hours) of clinical experience under physician supervision or in a collaborative setting

So, can a nurse practitioner own a medical spa in California? Not independently, and even the incoming 104 designation may not change that. Assembly Bill 890 created two NP categories: a 103 NP practices within a group and cannot be the sole medical director, while a 104 NP gains full independent clinical practice authority within their certified population focus.

The 104 designation becomes available January 1, 2026, and reaching it takes roughly six years: three years as a 103 NP on top of the transition-to-practice period.

But Assembly Bill 890 governs clinical practice, not business ownership. It doesn’t override California’s Corporate Practice of Medicine doctrine or the Moscone-Knox Professional Corporation Act, which still cap a non-physician’s stake in a professional medical corporation at 49%, with a physician holding the majority.

Whether a 104 NP can independently own or act as sole medical director of a med-spa-style practice is unsettled as of 2026, so confirm your specific setup with a healthcare attorney.

The law also states that after meeting these requirements, NPs can open a med spa and practice independently only in a defined setting, such as clinics, healthcare facilities, state or federal facilities, or certain group practices. 

Regarding the scope of practice, they’re also allowed to diagnose and treat conditions, prescribe medications, and manage patient care within the limits of their training and certification.

California laws and regulations for opening a med spa

Opening a med spa in California, like in any US state, requires careful attention to compliance with state and federal regulations.

Here is a quick guide to your key laws and regulations.

Registering as a professional corporation

California law dictates that medical spas register as Professional Corporations (PCs). This legal structure is specifically designed for healthcare providers, and because medical spas offer medical services, they must comply with the corporate aspect of medicine rules.

Before filing, drafting a medical spa business plan helps clarify your ownership and management structure, your startup costs — including recurring software subscriptions, where a comparison like our Practice Better pricing breakdown helps you budget — and how the professional corporation and any MSO will fit together. The steps to forming your med spa as a Californian Professional Corporation are:

• Filing incorporation articles: Details about your corporation’s chosen name and purpose, etc.
• Initial statement of information: It must be submitted within 90 days of incorporation and include details like the names and addresses of your corporate directors and officers. This is filed annually, and applicants must pay a $25 fee.
• Corporate governance documents 
• Tax IDs, licenses, and updated regulatory filings 

Important to note: 

There are some limitations on name choice, so you must choose a business name that is distinguishable from other registered businesses.

The name of the med spa as a professional corporation must include the name or surname of one or more of the shareholders who are licensed physicians, for example, Sarah Jackson, M.D., Professional Corporation.

Medical director

A medical spa in California requires a medical director to oversee medical procedures. This person must be a licensed physician holding a valid medical license from the California Medical Board.

The medical director is responsible for monitoring and delegating medical treatments within their scope of practice. NPs cannot currently serve in this role in California.

Whether a nurse practitioner can be a medical director depends on the state. Reaching full-practice-authority status under Assembly Bill 890 may not be enough on its own, since California’s Corporate Practice of Medicine rules still cap non-physician ownership, so this is worth confirming with a healthcare attorney.

Because nurses and other non-physicians cannot own the medical entity, most med spas contract a physician to serve as medical director rather than employing one full time. Budget for that retainer to run roughly $2,000 to $8,000 or more a month in California, depending on how involved the physician is and the range of medical treatments you offer.

Licenses and permits

Med spa licenses exist to confirm that a business is legal and that its services are performed by qualified professionals. Meeting California’s med spa licensing requirements is the first step toward compliance, whether you are opening a med spa or looking to start a private practice in California as an LCSW.

The medical licensing requirements for all med spas across the US are:

• General business license
• Registering with the state medical board  
• Getting a federal employer identification number (EIN)
• Getting a seller permit and sales tax certificate
• Fire and Health Department permits
• MSO and MSA
• Obtaining HIPAA compliance certifications
• Specialty certifications for advanced procedures
• Medical director license 
• Nursing licenses 
• Liability insurance

Apart from these, nurses must also obtain licenses that show they have the medical knowledge necessary to practice safely. Licensed nurses are those who have:

• Been accredited by bodies such as CCNE and ACEN
• Licensed by the California Board of Registered Nursing (BRN): Nurses must meet relevant educational requirements, pass a criminal background check, and pass the national licensing examination.
• Passed NCLEX-RN exam: To show that a nurse has the knowledge, skills, and abilities to practice nursing safely at the entry-level.

California Board of Barbering and Cosmetology

Med spas typically offer a mix of invasive and non-invasive cosmetic procedures, not invasive treatments alone.

If your med spa offers facials, microdermabrasion, chemical peels, CoolSculpting, and other treatments of a similar nature, it must be registered with California’s Barbering and Cosmetology board. 

Before applying for a license there, NPs must ensure they qualify to take the State Boards examination. The required hours of training before taking the test are:

• Cosmetologist: At least 1,000 hours of training in a licensed cosmetology program.
• Esthetician: At least 600 hours of training in a licensed esthetics program.
• Electrologist: At least 600 hours of training in a licensed electrolysis program.

Also important, the Board cancels licenses that aren’t renewed for five years, and if you want to be licensed again, you must apply for and pass the examination again. Requirements vary by state. For comparison, see our breakdown of Texas cosmetology license requirements.

Insurance and liability

Med spas need liability insurance that covers claims of negligence, errors, or omissions, along with property risks like fire, flood, and theft. One uninsured incident can be enough to shut a med spa down.

Legal compliance

Legal compliance with California’s healthcare and business regulations means meeting requirements such as:

• Patient consent: Med spas must obtain informed, signed consent before any medical treatment, covering the procedure, its benefits, and its risks. A botulinum toxin consent form or chemical peel consent form covers the specifics for those procedures.
• More consent templates: An anti-wrinkle consent form or advanced treatment consultation form covers other common med spa procedures.
• Data privacy: Med spas must follow HIPAA rules by using secure systems with strong encryption, so only authorized personnel can access client medical records.
• Operational standards: Facilities must maintain strict hygiene protocols, including proper equipment sterilization and infection control.
• Aftercare instructions: Procedure-specific templates, like AccuTite aftercare instructions or Emtone aftercare instructions, help patients recover safely and keep documentation consistent.
