Do ESA letters expire? Federal law sets no fixed expiration date for an ESA letter, but in practice most housing providers treat an ESA letter as current for about one year. Because your mental health condition and treatment plan can change, a landlord or property manager may ask for an up-to-date ESA letter at annual lease renewals. To keep your housing rights secure, most people renew your ESA letter every year with a licensed mental health professional.
Do ESA letters have an expiration date?
An ESA letter does not carry a legal esa letter expiration date the way a driver’s license does. What it carries is a date of issue. Housing providers and property managers look at that date and generally expect a current letter – one issued within the past 12 months. So while the law does not say esa letters expire on a specific day, the practical answer to ‘do esa letters expire’ is that a letter more than a year old is often treated as out of date.
Why housing providers want a current ESA letter
Housing providers want current documentation because the Fair Housing Act lets them verify that you still have a qualifying mental health condition and still benefit from an emotional support animal. A licensed mental health professional confirms your ongoing need. A letter that is up to date shows the accommodation is still medically appropriate, which is why an annual renewal has become the norm even though no federal rule sets a hard expiration.
The one-year rule of thumb
The common one-year standard comes from how landlords handle lease renewals and reasonable accommodation requests. Many property managers ask for a new esa letter, or confirmation that your current letter is still valid, once a year. Treating an ESA letter as good for 12 months keeps you aligned with what most housing providers expect and prevents a lapse during a lease renewal or a move.
What makes an ESA letter valid
A valid esa letter comes from a licensed mental health professional – a licensed therapist, clinical social worker, psychologist, or psychiatrist – who has evaluated you. It appears on official letterhead, names your qualifying mental health condition, and includes the provider’s license number and signature. An official esa letter without a license number, or one bought from an instant online service with no evaluation, may be treated as an invalid or expired letter regardless of its date.
How to renew your ESA letter
The esa letter renewal process mirrors getting the original letter. You reconnect with a licensed mental health professional, briefly review your mental health treatment and current symptoms, and – if the professional determines the emotional support animal still helps – receive a renewed letter with a fresh date. Many telehealth services that follow HUD guidelines offer annual renewals, and your own licensed therapist can issue an updated letter too.
Do you need a new letter every year?
Legally, you are not required to get a new esa letter on a set schedule. Practically, annual renewals are the safest approach because housing providers commonly ask for current documentation at lease renewals. If you keep the same home and your landlord does not request an updated letter, your current letter may continue to serve. But if you move or renew a lease, expect to show an up-to-date ESA letter.
What happens if your ESA letter is out of date?
If a housing provider considers your ESA letter expired or out of date, they can ask for current documentation before approving or continuing your accommodation. An expired letter does not erase your rights, but it can create unnecessary stress and delay while you obtain a new letter. Getting ahead of the expiration date – renewing before a lease renewal – avoids a gap in your housing protections.
ESA letters for travel
Air travel is a special case. Since the 2021 DOT rule under the Air Carrier Access Act, most airlines no longer accept emotional support animals in the cabin at all, so an ESA letter – current or not – generally will not get an emotional support animal a cabin seat. Only trained service dogs keep cabin access. For housing, though, a current ESA letter remains the key document.
Avoiding ESA letter scams
ESA letter scams often advertise instant letters, instant approval, or a permanent letter that never needs renewal. Those online esa letters frequently lack a real licensed professional and a valid license number, so housing providers reject them. A legitimate esa letter – and a legitimate renewal – always involves a licensed mental health professional and current documentation. If a service promises a letter with no expiration and no evaluation, treat it as a red flag.
ESA letters and pet fees
A current, valid ESA letter supports a reasonable accommodation that waives pet fees, pet deposits, and monthly pet rent, because an emotional support animal is not treated as an ordinary pet under a no pets policy. If your letter lapses, a landlord could argue the accommodation no longer applies and charge pet fees again – another reason to keep the letter up to date.
Keeping your documentation current
The simplest approach is to calendar an annual renewal near your original letter’s date. Keep your current letter, your provider’s contact information, and any accommodation request records together. If your mental health conditions or treatment plan change, an updated letter reflects that. Staying current means you are never scrambling to prove your housing rights when a property manager asks.

Who can renew your ESA letter?
Only a licensed mental health professional can renew your esa letter – the same category of provider who can issue one. USAR does not write or renew ESA letters; we recommend established providers like CertaPet, Pettable, and ESA Doctors, or your own licensed therapist. A renewal from clinical social workers or other licensed professionals keeps your documentation legitimate and your housing protections intact.
What an ESA letter actually is
Before asking whether an ESA letter expires, it helps to be clear on what an ESA letter is. An ESA letter is a signed statement from a licensed mental health professional confirming that you have a mental health condition and that an emotional support animal supports your mental health treatment. The emotional support animal letter is the document housing providers rely on, and its date is what raises the expiration question. Because mental health needs can change, the ESA letter is meant to reflect your current mental health, which is why a fresh ESA letter each year keeps your documentation aligned with your mental health condition today.
How a mental health professional handles renewals
A licensed mental health professional handles an ESA letter renewal much like the original. The mental health professional reviews your mental health, confirms the emotional support animal still helps your mental health conditions, and issues a new ESA letter with a current date. Some people see the same licensed therapist each year; others use a telehealth mental health professional. Either way, only a licensed mental health professional can renew an ESA letter – no website can issue a valid ESA letter without a real mental health evaluation, so the renewed ESA letter carries the same weight as the first.
ESA letters vs. service animals at renewal
Unlike service animals, emotional support animals rely entirely on the ESA letter for their rights, so keeping the ESA letter current matters more for an ESA than for a trained service dog. Service animals prove themselves through trained tasks; an emotional support animal proves its need through the ESA letter and the mental health professional behind it. That is why the renewal question comes up so often for ESA owners – the emotional support animal letter is the whole basis of the accommodation, and an out-of-date letter is easier for a landlord to question than a working service dog.
Housing accommodations and your ESA letter
Your ESA letter supports housing accommodations under the Fair Housing Act. When you submit an accommodation request, the housing provider looks at the ESA letter to confirm a qualifying mental health condition. A current ESA letter makes the housing accommodations straightforward; an expired ESA letter can slow them down. The Fair Housing Act, administered by Housing and Urban Development, protects the accommodation, but the ESA letter is the document that carries it, so keeping the emotional support animal letter up to date protects your housing rights.
Signs your ESA letter needs renewing
A few signs tell you it is time to renew your ESA letter: the letter is nearing 12 months old, you are moving, your lease is up for renewal, or a property manager has asked for current documentation. If your mental health conditions or mental health treatment have changed, a renewed ESA letter reflects that too. Renewing before the letter looks expired avoids unnecessary stress and keeps your emotional support animal’s protections intact under fair housing law.
Avoiding fake and expired ESA letters
Watch for services that sell a permanent ESA letter that never expires or promise instant approval – these online esa letters often skip the mental health evaluation and lack a real license number, so housing providers treat them like expired esa letters. A legitimate esa letter, current and valid, always comes from a licensed mental health professional. If you are ever unsure whether your ESA letter is up to date, a quick renewal with a licensed professional settles it and keeps your mental health documentation credible.
ESA letters and mental health conditions
An ESA letter is tied to your mental health conditions, so its value depends on staying current with your mental health. Common mental health conditions that support an ESA – anxiety, depression, PTSD, and bipolar disorder among other mental health challenges – are ongoing, and a licensed professional confirms the therapeutic benefit each time. When your ESA letter reflects your current mental health conditions and medical necessity, it stands as strong legal documentation of your need, and its legal protections under fair housing law hold up.
Is registration or documentation required?
No ESA registration is required, and no ESA registration replaces the letter – federal law recognizes no registry, so an esa registration is voluntary at best. What housing providers want is real esa documentation: a current, official ESA letter from licensed professionals. An emotional support animal needs no specific training, unlike a service dog, so the ESA letter and its renewal process are the whole basis of the accommodation. Keep good esa documentation and an ESA letter good for the year, and esa owners stay protected even under a strict no pets policy.
State laws and your ESA letter
Beyond federal law, some state laws add rules to how ESA letters work. A few states require an established relationship with the provider before an ESA letter is valid, and others limit online esa letters that skip an evaluation. These state laws sit on top of the Fair Housing Act, so an assistance animal accommodation may look slightly different where you live. When in doubt, a licensed professional who knows your state’s ESA letter expiration norms keeps your documentation compliant.
