Clinician-led, not a registry

ESA letters and PSD evaluations from licensed professionals

We connect people who need assistance-animal documentation with mental health professionals licensed in their own state — then make the resulting letter easy for a landlord to verify.

State-licensed review

Your case goes to a professional whose license covers where you live — not a generic national queue.

Fair-housing wording

Letters are written for a reasonable-accommodation request, with credentials and a current date on the page.

Diagnosis stays private

A housing provider can confirm the letter is genuine without ever receiving your clinical details.

No registry claims

We do not sell registration numbers, vests or certificates as a substitute for clinical documentation.

What we issue

Two documents, two entirely different legal questions

Most confusion in this industry comes from blurring these together. National Service Pets keeps them separate, because a housing provider and a business are applying different laws.

Emotional support animal

The ESA housing letter

An ESA letter is a licensed clinician's written opinion that you have a disability-related need for an assistance animal where you live. It is the document a landlord, HOA or campus housing office actually evaluates under the Fair Housing Act — and the reason pet rent, pet deposits and breed or weight limits generally stop applying once the accommodation is approved.

  • Written for a reasonable-accommodation request, not for public access
  • Names the clinician, license type and jurisdiction
  • Requires no training of the animal — your existing pet usually qualifies
  • Covers dogs, cats and other ordinary household animals
How to get an ESA letter

Psychiatric service dog

The PSD evaluation

A PSD evaluation documents a psychiatric disability and the specific work a dog has been trained to perform because of it — interrupting a panic episode, retrieving medication, performing a room search, applying deep pressure on command. Under the ADA it is the training that creates service-dog status; our evaluation supports the disability side of that equation.

  • Assesses functional limitation, not a diagnosis label alone
  • Records the specific trained tasks you report
  • Deliberately kept separate from emotional-support wording
  • Never trains, tests or certifies the dog — no such certification exists

Our standard

A letter should be clinical, current, and easy to verify.

National Service Pets was rebuilt around that principle. Clients complete a secure intake, a licensed provider evaluates the need, and qualified clients receive documentation that explains the disability-related role of the animal without exposing private clinical detail.

The result is a cleaner experience for clients, clinicians, landlords, and property managers: less confusion, fewer unsupported claims, and a direct way to confirm authenticity.

The distinction that matters

Why a clinician letter outranks any ESA registration

There is no federal registry of emotional support animals or service dogs. Sites selling registration numbers are selling a product with no legal effect — here is what a housing provider is actually looking at instead.

Operating model

A clinical workflow built around documentation quality.

The process is intentionally structured so clients, clinicians, and housing providers know what each step is designed to accomplish.

01

Screen

Clients share the support need, housing context, and animal information through a secure intake.

02

Review

A licensed professional evaluates whether ESA or PSD documentation is clinically appropriate.

03

Issue

Approved clients receive current documentation written for practical housing use and verification.

04

Support

Support teams help with document access, verification questions, renewals, and landlord follow-up.

What we do

Keep the request grounded in clinical review.

  • Route clients to licensed professionals for case review.
  • Write eligible letters for housing accommodation requests.
  • Protect diagnosis details while explaining disability-related need.
  • Provide a verification path for housing providers.

What we avoid

No shortcuts that confuse clients or landlords.

  • No animal registry claims as a replacement for a clinician letter.
  • No promise that an ESA has public-access rights like a service dog.
  • No automatic approvals without professional review.
  • No unnecessary disclosure of private diagnosis information.

Nationwide footprint

Licensed ESA and PSD review in all 50 states.

Because the clinician must be licensed where you live, the network is organised by state. Every state service-area brand routes into the same National Service Pets intake, review and verification standard.
