The Personal Service Permit lets a licensed pro take a few simple services to a client's door. But what if you want to bring the whole salon? In California, that is a different setup entirely — a licensed mobile unit, a full salon built into a vehicle. It opens up far more than the PSP allows, but it comes with its own rulebook. Here is what running a salon on wheels actually requires.
The short answer
A mobile unit is a licensed establishment that happens to be on wheels. Because the Board licenses and inspects it like any brick-and-mortar salon, it is not held to the short menu a Personal Service Permit allows — the same health and safety rules that govern a fixed salon apply inside the vehicle. The trade-off: you have to build a compliant unit, get it licensed, pass an inspection, and operate within a fixed service area.
Mobile unit vs. Personal Service Permit
These two get confused constantly, so here is the clean split:
- Personal Service Permit (PSP): an individual licensee performs a limited list of low-risk services — no chemicals, no machines — at homes, hotels, or events. We covered the PSP in detail here.
- Mobile unit: a licensed establishment inside a vehicle, inspected by the Board and staffed by licensees, offering services within the establishment's scope.
Put simply: the PSP is a permit for a person; a mobile unit is a license for a place that moves.
The 50-mile radius rule
A mobile unit is not licensed to roam the whole state. Its operating area is limited to the cities and counties where it holds permits to provide services, and it can extend no further than a 50-mile radius from the permanent base address the unit operates from. Choose that base address carefully — it defines how far you can legally travel for work.
How to get a mobile unit licensed
You apply to the Board on its mobile unit application form (Form #03A-202). Business and Professions Code section 7355 sets out what goes with it:
- A detailed floor plan showing the layout and dimensions of the unit — doors, windows, restroom, sinks, any lift or ramp, ventilation, and equipment.
- Proof you purchased or lease the unit and its equipment.
- A permanent base address the unit will operate from.
- City or county licenses and permits for each location where you plan to provide services.
- Proof of a valid California driver's license for the officer or employee responsible for driving the unit.
- Documentation that the unit meets plumbing, electrical, and fire code.
- A signed affidavit for each interested party, plus separate disclosures if anyone involved has a criminal conviction or prior license discipline.
- The application fee.
From there, the timeline runs like this:
- Within 10 calendar days, the Board tells you in writing whether your application is complete or what is missing.
- Within 21 calendar days of a completed filing, the Board issues its decision.
- That decision depends on you scheduling an inspection of the unit within 7 calendar days of being notified your application is complete.
The final inspection checks the unit against the Board's establishment requirements before you can operate.
What the vehicle itself has to have
The law defines a mobile unit as a self-contained, self-supporting, enclosed vehicle. Beyond that, Business and Professions Code section 7357 requires the unit to be equipped with working systems for:
- A self-contained, potable water supply — required if you offer shampooing services.
- A continuous, on-demand hot water tank of at least six-gallon capacity.
- Adequate ventilation.
The Board also expects the unit to be kept clean, in good repair, and in compliance the whole time it is licensed. That is what the inspection is verifying, and inspectors can return.
Safety and operation rules
Once licensed, a mobile unit follows the same health and safety rules as a fixed salon, plus a set of vehicle-specific requirements:
- Storage cabinet doors must have safety catches.
- Any equipment not stored in cabinets must be securely anchored to the unit.
- No services may be performed while the unit is in motion.
- If you serve clients with disabilities, the unit needs a ramp or lift for access.
- You must keep an itinerary of dates, locations, and service times available to a Board representative on request.
- A person licensed by the Board — anyone except an apprentice — must be in charge of the unit at all times.
- The owner is responsible for following all local, state, and federal laws for operating the vehicle itself.
Who a mobile unit fits
- Entrepreneurs who want to run a real salon business without a fixed storefront lease
- Established pros ready to invest in a built-out, inspected vehicle
- Operators targeting events, neighborhoods, or underserved areas within a set radius
- Owners who want to offer full services, not just the limited PSP menu
It starts with a license
Whether you picture a chair in someone's living room or a salon built into a van, none of it is legal until you are licensed. That is the first step. At Beyond 21st Century Beauty Academy in Santa Fe Springs, we train students for California licensure in cosmetology, esthetics, and manicuring.
