We recommend that you renew your ESA Letter annually for a few reasons: 1. Some states have laws requiring ESA owners to complete a clinical evaluation and renew their ESA Letter on a yearly basis. 2. Many housing providers refuse to accept an ESA Letter that is over a year old. Renewing your letter enables you to provide current documentation that verifies your need for an Emotional Support Animal as still relevant.  3. Licensed Therapists may not validate an outdated ESA Letter in the event the housing provider reaches out to verify. An annual consultation with a Licensed Therapist to discuss your needs for an ESA Letter is advised in order to keep recommendations current.
