Summary

Pets kept in City-publicly-financed rental housing must be implanted with an electronic animal identification microchip. Landlords who receive public financing from the City must allow tenants to keep pets that meet this requirement.

Each pet maintained pursuant to this article shall be spayed or neutered, vaccinated, implanted with an electronic animal identification device (microchip) and, if required, licensed. The pet shall be maintained consistent with all state and local laws and regulations, and not constitute a nuisance to the housing development and/or to the other tenants. (LAMC § 51.22 B)

'Pet' means a common household domesticated animal such as a dog, cat, rabbit, bird, mouse, rat or similar small rodent, fish or turtle that is kept in the home for pleasure rather than for commercial purposes. 'Pet' does not include any equine (including any horse, pony, donkey, burro or mule), swine, sheep, goat, cattle, poultry or other similar livestock. (LAMC § 51.21 B)

Full Breakdown

LAMC § 51.22 B requires that every pet in a publicly-financed housing development be 'implanted with an electronic animal identification device (microchip),' in addition to being spayed/neutered, vaccinated, and licensed if required. This rule applies to new publicly-financed multifamily developments and to existing ones that receive additional City financing or contractual amendments after August 25, 2019. The definition of 'Pet' in § 51.21 B includes dogs, cats, rabbits, birds, mice, rats, fish, and turtles, but not livestock or equines. The microchipping requirement is a condition for the tenant's right to keep a pet in that housing, not a standalone citywide mandate.

Violations & Fines

Violations subject landlords to civil liability including actual damages or three times one month's rent (whichever is higher), plus attorney's fees. Tenants may also assert the provision as an affirmative defense in an unlawful detainer action involving pet ownership.

Frequently Asked Questions

Is microchipping required for all pets in Los Angeles?
LAMC § 51.22 requires microchipping only for pets in City-publicly-financed housing. The broader LA microchipping and licensing rules for the general public are in LAMC Chapter V (§ 53.xx), which covers all dogs and cats citywide.
What counts as a 'pet' under this microchipping rule?
Under § 51.21 B, 'Pet' means a common household domesticated animal such as a dog, cat, rabbit, bird, mouse, rat or similar small rodent, fish or turtle kept for pleasure. It does not include horses, pigs, sheep, goats, cattle, or poultry.
Does this rule apply to my apartment building that has a Section 8 rental subsidy?
No. 'Public Financing or Publicly Financed' under § 51.21 C means a loan and/or grant from or through the City used to build new multifamily units. It expressly excludes federal or state rental subsidies such as Section 8 vouchers under 42 U.S.C. § 1437f.
