Yorba Linda, CA Home Business: Zoning & Home Occupation Permits (2026)

Yorba Linda Municipal Code Section 18.20.100 sets ten regulations that every home occupation permitted under the zoning regulations must satisfy. The business must be conducted within the dwelling and remain clearly incidental to its use as a residence under Subsection B, with only limited stock-in-trade that does not hinder parking in the garage under Subsection A. Subsection C bars any external alteration of the dwelling and requires that the home occupation not be apparent beyond the site's boundaries, except for a nameplate permitted under Chapter 18.24.

Staffing is capped at one non-resident employee working on the premises under Subsection D, and Subsection E limits motor or mechanical equipment to what is normally incidental to residential use, which forecloses commercial-scale auto repair or shop equipment. Subsections F and G prohibit radio or television interference, noise audible beyond the site, and any emission of smoke, odor, liquid or solid waste. Subsection H limits the site to one vehicle or trailer beyond those normally incidental to residential use, cross-referencing the parking standards in Section 18.10.100.C, and Subsection I bars pedestrian, automobile or truck traffic significantly exceeding the normal amount for the district.

Subsection J specifically bars renting a short-term residential rental unit for weddings, parties or receptions typically held at a banquet facility, limiting such units to uses incidental to dwelling, lodging or sleeping. Enforcement for any violation of these standards runs through the City's general zoning enforcement and abatement authority under the municipal code, since the home occupation loses its permitted status once any standard is breached.
