How to open a med spa in Washington

1. Can you own a med spa?

Who is allowed to own the business, and in what corporate form?

Washington channels ownership through the Professional Service Corporation Act: shares may be held by the people licensed to render the service the corporation was organized to render.

2. The medical oversight you will need

Which physician relationship the state requires, and what they must do.

Washington answers the supervision question twice, because it has two rules and they disagree on purpose. For a delegated LLRP DEVICE — a laser, noncoherent light, IPL, radiofrequency or plasma device that topically penetrates and alters tissue — the physician must be ON THE PREMISES for the patient’s first treatment. For a cosmetic INJECTION it turns on the label: on-site for the whole procedure if the substance is used off-label, and merely reachable within thirty minutes if it is FDA-approved for that use.

3. What has to happen before a patient is treated

The exam or provider-patient relationship required before the first injection.

Washington writes out SEVEN things a physician must do before authorizing a nonsurgical medical cosmetic procedure, rather than naming a “good-faith exam”. The same seven attach whether the procedure is an injection or an energy device.

4. Who may actually inject

Whether an RN, NP, or PA may treat, and under whose supervision.

Registered nursing in Washington expressly includes executing a medical regimen prescribed by a physician, physician assistant or ARNP — and separately includes delegation. An ARNP’s expanded role is defined by the nursing board rather than by statute.

5. What it costs — the part that is a legal question

We do not publish build-out cost estimates. Fit-out, equipment, lease and staffing are real costs and they are not regulatory monitoring — any figure we gave you would be someone else’s estimate with our name on it. What we can tell you, cited, is which of Washington’s requirements are also spending decisions, because those are the ones that are not optional and the ones with dates attached.

• The physician relationship

  Whatever the state requires here is a recurring cost, not a one-off — a medical director or delegating physician is a paid relationship for as long as you operate.

  Using a laser, noncoherent light, intense pulsed light, radiofrequency or plasma device that topically penetrates skin and alters human tissue — an “LLRP device”, and one the FDA classifies as a prescription device — IS THE PRACTICE OF MEDICINE under RCW 18.71.011. Washington settles the threshold question in the rule itself rather than leaving it to be argued.

• Registering the facility

  Where a state requires the premises itself to be registered or licensed, that is a filing with a timetable — and a date you can miss.

  ⚠️ RECONSTITUTING BOTOX IS NOT COMPOUNDING IN WASHINGTON, AND THE CARVE-OUT HAS A CLOCK IN IT. “Compounding” means “THE ACT OF COMBINING TWO OR MORE INGREDIENTS IN THE PREPARATION OF A PRESCRIPTION” — but “RECONSTITUTION AND MIXING OF (a) STERILE PRODUCTS ACCORDING TO FEDERAL FOOD AND DRUG ADMINISTRATION-APPROVED LABELING DOES NOT CONSTITUTE COMPOUNDING IF PREPARED PURSUANT TO A PRESCRIPTION AND ADMINISTERED IMMEDIATELY OR IN ACCORDANCE WITH PACKAGE LABELING”. Follow the label and inject; stray from it, or hold the vial beyond what the labeling allows, and the compounding regime attaches.

• The corporate structure

  The entity the state permits you to trade through determines what you pay to form and maintain it, and sometimes who has to be on the paperwork.

  ⚠️ WASHINGTON’S REBATE BAN REACHES THE SALE OF THE DRUG ITSELF, NOT JUST REFERRALS. It is unlawful to pay or allow, or for a licensee to request or receive, “DIRECTLY OR INDIRECTLY, A REBATE, REFUND, COMMISSION, UNEARNED DISCOUNT OR PROFIT BY MEANS OF A CREDIT OR OTHER VALUABLE CONSIDERATION IN CONNECTION WITH THE REFERRAL OF PATIENTS … OR … ON THE SALE, RENTAL, FURNISHING OR SUPPLYING OF … DRUGS, MEDICATION, OR MEDICAL SUPPLIES, OR ANY OTHER GOODS, SERVICES OR SUPPLIES PRESCRIBED FOR MEDICAL DIAGNOSIS, CARE OR TREATMENT.”

6. What you can put in the syringe

GLP-1 and peptide legality is federal and moves independently of Washingtonlaw — a compounded product can lose its basis nationwide with no change to your state’s rules. Check current standing before you build a service line around one.

Can that exam be done over telehealth in Washington?

⛔ WASHINGTON PUTS A TRAINING REQUIREMENT ON EVERYONE DOING TELEMEDICINE EXCEPT THE PHYSICIAN, WHICH IS THE OPPOSITE OF WHAT MOST OPERATORS ASSUME. Beginning January 1, 2021, “a health care professional who provides clinical services through telemedicine, other than a physician licensed under chapter 18.71 RCW or an osteopathic physician licensed under chapter 18.57 RCW, shall complete a telemedicine training.” The training “Must include information on current state and federal law, liability, informed consent” and other criteria set by the telemedicine collaborative, and “If a health care professional completes the training, the health care professional shall sign and retain an attestation.” In a med spa that reaches the nurse, the advanced practice nurse and the physician assistant, and leaves the supervising physician out.

Does a med spa have to register or hold a license in Washington?

Washington creates NO MED-SPA LICENSE AND NO FACILITY REGISTRATION on the medical side. The cosmetology side does license premises, and prices them: a Salon/Shop license is $121 to get and $121 to renew, against $35 for an esthetician. ⚠️ BUT THE DRUG LAW DECIDES WHAT THE ROOM MAY HOLD: reconstituting a sterile product to its FDA labeling, on a prescription, ADMINISTERED IMMEDIATELY or per package labeling, is NOT compounding — stray from the label and it is. Anything actually compounded for a practitioner’s office use must meet USP standards, the seller stays responsible for its quality, and adulterating a drug is a MISDEMEANOR carrying forfeiture. (Wash. Rev. Code § 18.64.011 (“compounding”); verified 2026-09-02) This is regulatory monitoring, not legal advice.
