Our editorial policy

Our research begins with primary sources. On housing, that means the Fair Housing Act itself, the HUD rule at 24 CFR 100.204, the Joint Statement on reasonable accommodations that HUD and the Justice Department issued in 2004, and whatever HUD guidance is currently in force. Public access questions go to ADA.gov, and air travel questions go to the federal Department of Transportation.

State rules come from each state's own statutes and agency pages. Health topics draw on NIMH, MedlinePlus, NAMI and the National Center for PTSD run by the VA, plus peer-reviewed studies indexed on PubMed whenever we talk about evidence.

We read every source we cite. If a source does not load or does not support the point, we do not cite it.

Much of what is written about emotional support animals online is out of date or written to sell products such as registrations or ID cards that have no legal effect. Official sources let you check our work and see the exact wording that applies to you.

Each page lists its sources so you can follow them. Where a source is a summary rather than the law itself, we say so, and where rules differ by state, we point you to your state guide.

• Federal agencies, including HUD, the Justice Department and the Department of Transportation
• Statutes and regulations, including eCFR and official state legislature sites
• Health bodies such as NIMH, MedlinePlus, NAMI and the VA
• Peer-reviewed research, described honestly when evidence is limited or mixed

Dr. Andrew Patel is a physician. He looks over evaluations and signs ESA letters when the clinical findings justify one, and he also checks the content published on this site from a clinical standpoint.

In reviewing pages, he checks that mental health conditions are portrayed accurately and with respect, that we are candid about the limits of the evidence, and that each page makes clear an ESA is no substitute for treatment. Condition pages also point readers to 988 or 911 if they are in crisis.

A few rules never bend. We state clearly that an ESA falls outside the ADA's service animal category, so it has no right to enter public places. We never claim a landlord, school or airline is obligated to accept an ESA.

We explain that FHEO-2020-01, HUD's 2020 notice on assistance animals, stopped counting as guidance on September 17, 2025, when HUD's withdrawal took effect, and that guidance HUD issued in May 2026 gives untrained ESAs no presumption of reasonableness. You won't see us call an ESA letter certified, registered or official, because no such status exists, and you won't find testimonials or made-up statistics here.

We monitor federal and state changes that affect emotional support animals, including HUD guidance, Department of Transportation rules and new state laws. When something changes, we update the affected pages and their sources.

We also re-check older pages on a regular basis to confirm that links still work and that the information is still current. Because rules can change quickly, always check the date and sources on any page and confirm with your housing provider or an attorney when your situation depends on it.

We describe mental health conditions in plain, respectful language, drawing on sources such as NIMH, NAMI and MedlinePlus. We steer clear of wording that stigmatizes anyone living with mental illness.

When we discuss how animals may help, we are honest that research on animals and mental health is mixed and often limited. We never present an emotional support animal as a treatment or as a substitute for therapy or medication. Pages on conditions or crisis topics tell readers they can dial or text 988, or dial 911, for immediate help.

ESA Letter Therapist sells ESA letter evaluations, and we are open about that. Our content is written to inform you, including when an ESA letter may not help, such as for public places, flights or workplaces.

Clinical decisions about letters are made only by licensed therapists during evaluations and are never influenced by our content or marketing.
