Rancho Cucamonga, CA Animal Ordinances: Cat Rules (2026)

020-1, adopted under Development Code Sec. 020, Standards for Animal Keeping, sets the maximum number of domestic pets allowed per lot in every zoning district. For cats, the limit is three animals on lots smaller than 7,200 square feet, three on lots between 7,200 and 9,999 square feet, and four on lots of 10,000 square feet or larger, applying in "all zones" rather than only agricultural or low-density districts. Dogs are capped at the same numbers. The cap applies per lot, and Sec. 020(A)(1)(b) allows combining different animal group types on one property as long as each type stays under its own maximum and the lot meets the minimum size for that animal type.

Kittens are exempt from the count while nursing: Sec. " The chapter's stated purpose, Sec. 010, is to prevent animal keeping from creating "dust, fumes, noise, odor, insect or vermin infestations, or visual blight" for neighbors, which is the basis code enforcement cites when responding to a complaint about too many cats at one address. Because this is a zoning standard rather than a criminal animal-control statute, enforcement runs through the Planning/Code Enforcement Division under Sec. 00 for repeat offenses within a year, with each day of a continuing over-limit household treated as a separate offense.
