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

The Tustin City Code lists home occupation standards in Article 9, Zoning, under Section 9271gg. Every home occupation operating in the City of Tustin has to satisfy each standard listed there: no employees unless they live on the premises, no stock-in-trade or commodity sold on-site, no mechanical or electrical equipment beyond what's customary for housekeeping, no outside operations or storage, no alteration to the residential appearance of the property, and no activity that emits smoke, dust, fumes, odors, vibrations, glare or electrical disturbance onto a neighboring property.

A ninth standard bars parking or using any vehicle over three-fourths ton carrying capacity at the home, ruling out box trucks and heavy-duty pickups tied to a home business. The current text traces to Ordinance No. 1524 (adopted August 16, 2022) and Ordinance No. 1536 (adopted April 16, 2024), which amended the traffic and parking standard now found at subsection viii. Tustin's Community Development Department reviews compliance as part of any related business license or zoning inquiry, and Code Enforcement investigates complaints under the citywide public nuisance and administrative citation provisions of Chapter 1.

Because the section sits inside the Specific Provisions of the Zoning Code (Article 9, Chapter 2, Part 2), it applies on top of whatever base zoning district, R-1, R-2, E-4 or otherwise, governs the parcel; a home occupation that can't meet every listed condition isn't a permitted accessory use in that district.
