Emotional Support

Three decades. Real therapists. Honest paperwork.
NSAR has been a service-animal registry since 1995 — long before the “online ESA letter” industry existed. Every letter we issue is signed by a state-licensed therapist after a thorough clinical review of your intake. You can verify their state license number on your state’s public license registry before you pay.
Real licensed therapists
LCSW, LPC, LMFT, licensed psychologist — all in your state, all license-verifiable. Names + credentials published before you pay.

Your intake is encrypted at rest, every PHI access is audit-logged, and our letter discloses that you qualify — not your diagnosis. Built for compliance, not just appearance.
Reviews from real customers
Every review is tied to a verified paid order. We don't write our own reviews — and we don't hide the bad ones.

Emotional Support Animals
Your home, your peace, your animal at your side.
An ESA is a companion animal that a licensed clinician determines provides therapeutic benefit for a qualifying mental-health condition. ESA housing protection changed in 2026 — HUD now enforces the Fair Housing Act only for trained service animals, so whether an untrained ESA is protected depends largely on your state’s law.
- Housing: Depends on your state after HUD’s 2026 change.
- Travel: Limited. Most U.S. airlines treat ESAs as pets after the 2021 DOT rule.
- Public access: No — ESAs aren’t covered by the ADA.
Common questions
- Does my landlord have to accept it?
No one can guarantee it. The letter is supporting documentation that aids a reasonable-accommodation request — it doesn’t force a landlord. Trained service animals stay FHA-protected; for an ESA it now depends on your state. - Can my landlord charge a pet deposit?
For a trained assistance animal, no. For an untrained ESA it now depends on your state law after HUD’s 2026 change. - Is an ESA the same as a service dog?
No — different roles, different rights. See the comparison →
Service Dogs
A working partner. Trained for your disability.
A service dog is a dog individually trained to perform tasks that mitigate a specific disability — physical or psychiatric. The ADA protects them in restaurants, stores, hotels, planes, and your apartment. The ADA also lets you train the dog yourself.
- Public access: Yes — under the ADA’s two-question rule.
- Housing: Yes — trained service animals remain FHA-protected.
- Travel: Yes — fly free in the cabin under the ACAA.
Want to self-train?
The ADA explicitly permits it. We’ve assembled the foundation curriculum, the public-access self-test, and six task-category playbooks (psychiatric · mobility · guide · seizure alert · hearing alert · medical assist) so you can do it right.

Three federal laws. Your state on top.
We translate the regulations into plain English so you can actually use them. Each topic links into a deep-dive with citations, the “in plain English” version, and scripts for the disputes that come up.

Training
Self-train your service dog.
The ADA permits it.
The ADA does not require professional training — you can train the dog yourself, and many handlers do. We’ll show you the order of operations: foundation manners first, public-access proofing second, task work last. Or if self-training isn’t the right fit, we’ll point you to vetted trainers in your state.
