Public Health and Welfare California 3 Minutes Read · published February 05, 2026 Flag of California

In San Diego, California, owners, adopters and custodians of dogs and cats should know when sterilization is required and what exceptions may apply. The city’s animal services processes for adoption and release typically require spay or neuter prior to transfer or a signed sterilization agreement; exemptions for medical reasons or breeding permits can be available under specific conditions. This guide explains who must comply, typical exemptions, enforcement pathways, common violations, and practical steps to obtain surgery or a permit.

Overview

The City of San Diego delegates animal control, adoption, and enforcement to its Animal Services division. Animals adopted from city facilities are usually sterilized before release or are placed on an agreement that requires sterilization within a set timeframe. For program details see the Animal Services adoption information[1].

Who must comply

  • Adopters of dogs and cats from city shelters or contracted facilities.
  • Owners obtaining a new license where sterilization is a licensing condition.
  • Custodians who sign a sterilization agreement as a condition of animal release.
Sterilization agreements often include deadlines and proof requirements.

Exemptions

Common exemptions include documented medical contraindications certified by a licensed veterinarian and certain licensed breeders when permitted by local rules. The City of San Diego publishes exemption and adoption policies but does not always list every exception on a single page.

A veterinarian’s signed statement is the usual form of medical exemption evidence.

Penalties & Enforcement

Enforcement responsibility rests with City of San Diego Animal Services and its designated enforcement officers. Inspectors investigate complaints, issue notice letters, and may refer unresolved violations to administrative or court processes. Specific monetary fines for failing to comply with sterilization conditions are not specified on the cited Animal Services adoption page; see the municipal code or contact Animal Services for exact penalty schedules.
