ESA Letter in California, Done the Right Way

Yes. Since January 1, 2022, California Health & Safety Code § 122318 (AB 468) sets rules for anyone who writes documentation for an emotional support dog. The provider must be licensed where the documentation is provided, have a client relationship of at least 30 days, complete a clinical evaluation, and warn you that misrepresenting a dog as a service dog is a crime.

For an emotional support dog, California law does not allow the provider to issue documentation until a client-provider relationship has existed for at least 30 days. A legitimate California ESA letter for a dog therefore cannot be issued the same day as your first appointment. Be wary of any service that promises an instant California ESA letter for a dog.

The AB 468 requirements apply to documentation for emotional support dogs. Requests for other animals are still reasonable-accommodation requests under California fair housing law, and a landlord may ask for reliable documentation of your disability-related need.

A health care practitioner licensed in the jurisdiction where the documentation is provided, such as a licensed psychologist, licensed clinical social worker (LCSW), licensed marriage and family therapist (LMFT), licensed professional clinical counselor (LPCC), psychiatrist or physician. The letter must show the license number, type, jurisdiction and effective date.

A landlord must consider your request as a reasonable accommodation under California's Fair Employment and Housing Act (FEHA) and the federal Fair Housing Act. Since May 22, 2026, HUD reviews requests for untrained ESAs case by case at the federal level, but California's own fair housing law and the Civil Rights Department still apply. A request can be denied if the animal poses a direct threat or would cause substantial damage.

If your accommodation request is granted, ask in writing whether pet deposits, pet rent and breed or weight limits will be waived. California also limits security deposits generally under Civil Code § 1950.5. You remain responsible for any damage your animal causes.

Yes, in several ways. Passing off a dog as a guide, signal or service dog is a misdemeanor under Penal Code § 365.7, and businesses or providers that break California's ESA-dog documentation and seller-notice rules face civil penalties of $500, $1,000 and then $2,500 under Health & Safety Code § 122319.

No. Public-access rights under the ADA and California Civil Code § 54.2 belong to trained guide, signal and service dogs. Businesses may apply their own pet policies to emotional support animals.

Under the U.S. Department of Transportation's rules (14 CFR Part 382), airlines may treat emotional support animals as pets, so expect pet fees, carrier size limits and cabin caps. Check your airline's pet policy before booking. A trained psychiatric service dog is still accepted as a service animal.

University housing is covered by fair housing law, and schools that receive federal funding must also follow Section 504 of the Rehabilitation Act. UC, CSU and private campuses review ESA requests through disability or housing services, so start early, and allow for the 30-day rule if your ESA is a dog.

With the California Civil Rights Department within one year of the incident, or with HUD within one year. A private Fair Housing Act lawsuit can be filed within two years.

No. The licensed provider decides, based on your individual evaluation, whether an ESA recommendation is appropriate. If it isn't, no letter is issued.
