How Much Can an ESA Letter Save a Renter? The Real Numbers (Plus What Changed in 2025)

If you're renting with a pet — or thinking about getting one — the costs add up quietly. Pet rent. Pet deposits. Non-refundable pet fees. And in a high-cost city, the surcharges that come with bringing a dog or cat to a typical apartment can easily run $1,000 or more in the first year alone.

For renters with a documented mental health condition that benefits from an emotional support animal, the Fair Housing Act provides a different path. A properly-issued ESA letter from a licensed mental health professional is the foundation of a reasonable accommodation request — and when granted, that request typically eliminates every one of those surcharges.

Here's exactly what the savings look like in real numbers, what the law actually requires, and what changed after HUD's September 2025 guidance update.

The Real Cost of Renting with a Pet (2026 Data)

Across the US rental market, pet-related charges fall into three buckets:

Pet rent — A monthly surcharge added to your base rent. Per RentCafe's 2026 housing data, the national average is $35.65/month, with small cities averaging $34.88 and large cities $37.14. High-demand urban markets often charge $50–$75/month.

Pet deposit — A one-time, refundable security deposit charged in addition to the standard security deposit. Industry sources put the national average between $200 and $500, with $300 being a typical figure.

Pet fee — A one-time, non-refundable charge that some landlords use instead of (or in addition to) a refundable pet deposit. These typically run $100–$300 per pet.

Add it all together for a typical first-year scenario:

| Cost | Average | High-cost market | |---|---|---| | Pet rent ($35/mo × 12) | $420 | $900 ($75/mo) | | Pet deposit (refundable) | $300 | $500 | | Pet fee (non-refundable) | $200 | $400 | | First-year total | ~$920 | ~$1,800 | | Each subsequent year | ~$420 | ~$900 |

The deposit comes back if there's no damage. The fee and the rent don't.

How an ESA Letter Changes the Math

The Fair Housing Act, codified at 42 U.S.C. § 3604(f)(3)(B), requires landlords to make "reasonable accommodations in rules, policies, practices, or services" when those accommodations are necessary for a person with a disability to "use and enjoy" their dwelling.

In plain English: if your housing provider has a no-pets rule, a pet weight limit, breed restrictions, or pet-related fees, they have to evaluate whether to set those rules aside for your assistance animal. The animal isn't being treated as a "pet" — it's being treated as a medical accommodation, like a wheelchair ramp or a grab bar.

For the past several decades, the well-established interpretation has been that pet fees, deposits, and pet rent don't apply to assistance animals. A 2010 HUD memo on the topic stated this explicitly, and federal courts repeatedly upheld it.

What Changed in September 2025

Two things you should know about the current legal landscape:

1. HUD withdrew its formal guidance documents. In a September 17, 2025 memorandum, HUD formally withdrew FHEO Notice 2020-01 (the assistance-animal guidance) and FHEO Notice 2013-01. HUD cited the Supreme Court's Loper Bright decision and concerns that the prior guidance "exceeded HUD's statutory authority."

Important: the withdrawal does NOT change the underlying Fair Housing Act statute. Reasonable accommodation is still required by law. What's gone is HUD's specific interpretation of how to evaluate ESA requests — meaning housing providers and tenants now work directly from the statute itself.

2. A 2025 court decision raised the bar. In Henderson v. Five Properties LLC (U.S. District Court, Eastern District of Louisiana), the court held that a tenant requesting a fee waiver must show the waiver is both necessary and reasonable for their specific situation — not that the waiver is automatic just because the animal is an ESA. The judge specifically rejected the idea that HUD's prior guidance always required automatic waivers.

What this means in practice: Most housing providers — especially large property-management companies, REITs, and student housing operators — continue to grant ESA fee waivers as a matter of course because the cost of contesting one isn't worth the risk of a fair housing complaint. But the legal certainty has shifted. A landlord who wants to push back now has more room to argue, and tenants need to present their requests carefully and completely.

What the FHA Definitely Still Waives

When a reasonable-accommodation request is properly submitted and granted, here's what generally goes away:

• Pet rent — the monthly surcharge for having an animal
• Pet deposit — both refundable pet-specific deposits and non-refundable pet fees
• Breed restrictions — landlord pet policies that exclude pit bulls, rottweilers, dobermans, etc. don't apply to assistance animals
• Weight limits — pet weight caps (typically 25 or 50 lbs) don't apply
• Number-of-pets caps — if you need more than one ESA and have documentation supporting it
• No-pets policies — even buildings that prohibit pets entirely must consider an ESA accommodation

What the FHA Does NOT Waive

Three important categories of cost you're still responsible for:

1. The standard security deposit. This is the deposit every tenant pays, regardless of whether they have an animal. ESAs don't change this.

2. Damage your animal causes. If your dog scratches the hardwood, urinates on the carpet, or chews a doorframe, the cost of repair comes out of your standard security deposit (or you pay separately if it exceeds the deposit). The FHA accommodation doesn't shield you from damage liability.

3. The ongoing care of your animal. Food, vet bills, grooming, training, supplies — all on you. The reasonable accommodation is about housing rules; it doesn't subsidize ownership.

Who's Exempt From the FHA Entirely

The Fair Housing Act has narrow but real exemptions. If your housing falls into one of these categories, the FHA's reasonable-accommodation requirement doesn't apply:

• Owner-occupied buildings of four or fewer units — the classic "small landlord living onsite" exemption
• Single-family rentals owned by an individual who doesn't use a real estate agent or broker (and who doesn't own more than three such properties)
• Religious or membership-based housing that limits residency to members of a specific religion or organization
• Short-term hotels and motels

Most rental situations — apartment complexes, condo associations, HOAs, student housing, properties managed by property companies — are covered. If you're not sure whether your situation falls into an exemption, the HUD fair housing complaint process can help clarify.

What to Actually Do When You Submit a Request

The reasonable accommodation process is a written request to your landlord. The mechanics:

1. Get a properly-issued ESA letter. This must come from a licensed mental health professional in your state — therapist, psychologist, psychiatrist, social worker, or licensed counselor. The letter confirms (a) you have a disability under federal law and (b) the animal alleviates one or more symptoms of that disability. It does not need to disclose your specific diagnosis.

2. Submit the request in writing. Email is fine. State that you're requesting a reasonable accommodation under the Fair Housing Act for an assistance animal, attach your letter, and ask the landlord to confirm receipt and decision in writing. Keep copies of everything.

3. Give the landlord a reasonable time to respond. Most reasonable accommodation requests get a written response within 10 business days. If your request is denied or ignored, you have several options below.

4. Document everything. Keep dated copies of your letter, your request, your landlord's response, and any related communication. This becomes essential evidence if you need to escalate.

If Your Landlord Refuses

You have three primary options:

• File a HUD fair housing complaint at hud.gov/program_offices/fair_housing_equal_opp/online-complaint. HUD investigates at no cost to you and has authority to compel landlords to comply. Most cases settle before formal proceedings.
• Contact a fair housing attorney. Most metro areas have nonprofit fair housing legal services that take ESA discrimination cases pro bono. The National Fair Housing Alliance maintains a directory.
• Check state law. Many states (California, Massachusetts, New York, and others) have additional protections beyond federal FHA. Your state's fair housing or attorney general's office can confirm.

The Bottom Line

In an average US rental market, a granted ESA accommodation can save a renter roughly $900 in the first year and $420 every renewal year. In high-cost cities, the savings can run double that. Over a typical 3–5 year tenancy, the total can easily clear $2,000–$5,000.

The math only works, though, if your documentation is legitimate and the request is properly made. A letter from a non-clinical "registry" website is worse than no letter at all — those have been the basis for landlord refusals and even fraud findings in some cases. A real letter from a licensed clinician in your state, issued after an actual evaluation, is what the law was designed to recognize.
