San Clemente, CA Home Business: Zoning & Home Occupation Permits (2026)

Section 17.28.160(B)(1) requires a Home Occupation Permit under Section 17.16.140, plus a City business license under Chapter 5.04, whenever a business is conducted as an accessory use to a primary residential use, and this applies in any zone. Subsection C.3, Location, confirms that home occupations are allowed within legal residential dwelling units in all zones, meaning the permit process rather than the zoning map is what gates a home business citywide. The minimum standards in Subsection C then narrow what qualifies. Only residents of the dwelling unit may work in the business (C.1); equipment cannot create interference with radio, television, or telephone signals or voltage fluctuations reaching outside the unit, and electric motors are capped at a combined two horsepower (C.2, C.4); the business must run from an enclosed structure, either the main house or a permitted accessory building, without the structure's appearance changing enough that it no longer reads as residential (C.7); and nothing tied to the business may be stored outside or visible from outside (C.9).

Subsection C.12, Use, caps the whole operation at 20 percent of the habitable dwelling floor area and states the use shall be an incidental and accessory use that cannot change the dwelling's principal residential character. A permit is specific to both the permittee and the address: Subsection A.11 bars transferring or reassigning it to another person or to a different location. Conducting a home occupation outside an enclosed structure needs its own Conditional Use Permit, with narrow carve-outs for small-group outdoor swimming instruction and for licensed cottage food operations under Subsection D, which follow their own separate standards drawn from state Assembly Bill 1616 and California Health and Safety Code Section 114365.
