Fairfield, CA Animal Ordinances: Pet Limits (2026)

Fairfield's Animals and Fowl ordinance (Chapter 3) does not establish a maximum number of dogs or cats that may be kept at a single-family residence. Owners must, however, license all dogs four months and older through Solano County Animal Care Services, keep rabies vaccinations current, and prevent their animals from creating a nuisance through barking, odor, waste, or running at large. The number of fowl (chickens, ducks, geese, turkeys) is capped at three per parcel by Chapter 3, and lot-size and zoning rules apply to livestock. Anywhere the number of pets begins to create odor, noise, sanitation, or safety problems that affect neighbors, Code Compliance may abate the conditions as a nuisance under Chapter 27, and Solano County Animal Care can refer extreme cases for prosecution under California Penal Code Section 597.1 (failure to provide proper care, often used in hoarding cases). The Fairfield Housing Authority and many private landlords impose their own limits (typically one to two pets) that are stricter than city law.
