What limits does California place on a med spa's business structure?
Ownership · part of The Practice Perimeter
Short answer
The cited rules do not settle this — they govern ownership, not entity type: in a medical corporation, shares start with physicians, and only enumerated licensed professions may hold any, capped at 49% combined and never outnumbering the physician owners.
The exception is §13401.5, and it is closed and capped. Notwithstanding §13401(d), the licensed persons ENUMERATED in that section may be shareholders, officers, directors or professional employees of a medical corporation — so long as the sum of all shares owned by them does not exceed 49 PERCENT of the total. A profession not on the list does not qualify at any percentage, and a lay investor is not a licensed person at all.

⚠️ There is a SECOND cap most summaries omit, and it is a headcount rather than a percentage: the number of those other licensed persons owning shares may not exceed the number of persons licensed by the governmental agency that regulates the corporation. A medical corporation with one physician shareholder cannot admit two nurse practitioners as shareholders, however small their combined stake. The 49% arithmetic is necessary and not sufficient.

⚠️ California’s ban is broad and expressly survives co-ownership. The offer, delivery, receipt or acceptance by a licensee of “any rebate, refund, commission, preference, patronage dividend, discount, or other consideration, whether in the form of money or otherwise, as compensation or inducement for referring patients, clients, or customers” is unlawful — “irrespective of any membership, proprietary interest, or coownership in or with any person to whom these patients … are referred”. Shared ownership is not a defense.
