Tustin, CA Animal Ordinances: Chickens & Livestock (2026)

Section 4221(a)(2) caps most backyard fowl, including birds, chickens, and rabbits, at ten animals per parcel in combination, and flatly bars crowing-type birds or fowl except for roosters permitted under the following subsection. Section 4221(a)(3) then narrows rooster-keeping to a single rooster, and only on R-1 single-family lots that sit within the Cultural Resources Overlay District and measure at least 15,000 square feet; roosters are prohibited everywhere else in the City. Even a permitted rooster must be housed at least 100 feet from any dwelling, as close as possible to the rear property line, in a fully enclosed coop built of solid material that blocks light from sunset to sunrise and muffles crowing noise, and the coop must be screened from neighboring properties by a fence, hedge, or wall.

Livestock gets a separate, harsher rule: Section 4222 makes it unlawful to keep any equine, bovine, swine, sheep, or goat anywhere within Tustin's corporate limits except in the R-A District, or in a Planned Community District where development guidelines specifically authorize it, and even there a use permit is required before the animals can be kept. Section 4221(c) reinforces this by barring commercial keeping of animals or fowl in any residential zone other than R-A or an authorized PC district.
