Service animals, emotional-support animals, and reasonable accommodation duties under the federal Fair Housing Act and 43 Pa.C.S. § 955 (Pa. Human Relations Act).
Disability accommodation duties for Pennsylvania rentals come from two overlapping laws: the federal Fair Housing Act (42 U.S.C. 3604(f)) and the Pennsylvania Human Relations Act (43 P.S. 951-963). Pennsylvania does not add a stronger payment rule or a different process than the federal baseline, so the practical answers on who pays and how you respond track the FHA. The ADA itself mostly governs your public-facing spaces (the rental office, common areas open to the public), not the inside of a private unit. Two duties drive almost every dispute: making reasonable accommodations to your rules and permitting reasonable modifications to the physical space. This page explains the difference, who bears the cost, and the narrow grounds on which you can lawfully deny.

A reasonable accommodation is a change to a rule, policy, practice, or service under 42 U.S.C. 3604(f)(3)(B) - for example, waiving a no-pets policy for an assistance animal, assigning a closer parking space, or accepting rent a few days late from a tenant whose disability check arrives mid-month. A reasonable modification is a physical change to the dwelling under 42 U.S.C. 3604(f)(3)(A) - a grab bar, a ramp, a widened doorway, or a lowered thermostat. Both require a disability-related nexus: there must be an identifiable connection between the tenant's disability and what they are asking for. Pennsylvania's PHRA (43 P.S. 951-963) imposes the same duties in parallel, and it expressly protects tenants who use a guide or support animal. When the disability and the need are not obvious, you may ask for documentation confirming the disability and the disability-related need - but not the tenant's diagnosis or medical records.
This is the single most misunderstood rule. In private, unsubsidized housing, the FHA requires you to permit a reasonable modification, but the tenant pays for it (42 U.S.C. 3604(f)(3)(A)). You cannot refuse to allow the change, but you are not on the hook for the cost. You may also require, where reasonable, that the tenant restore the interior to its prior condition at move-out, reasonable wear and tear excepted - restoration of common-area changes like a ramp is generally not required. Accommodations (policy changes) are almost always cost-free to you, so the payment question rarely arises there. The rule flips for federally subsidized housing covered by Section 504 of the Rehabilitation Act (29 U.S.C. 794): there the housing provider must pay for both accommodations and structural modifications, unless doing so is an undue financial and administrative burden or fundamentally alters the program. Pennsylvania adds no state subsidy-payment rule beyond this - the who-pays answer is set federally.
When a tenant asks - and no magic words are required; a plain request tied to a disability is enough - you must engage in a good-faith interactive process. That means responding promptly, discussing the need, and, if the specific request is genuinely burdensome, proposing an alternative that is equally effective at removing the barrier. You are entitled to suggest a cheaper or less disruptive option, but you cannot simply stall. Under Pennsylvania practice and HUD guidance, an unreasonable delay or non-response is treated as a denial and can itself be discrimination. Document each request and your reply in writing: the date received, what you asked for, what you offered, and the outcome. That paper trail is your best defense if a complaint is filed.
A request to waive a no-pets policy for a service or support animal is a reasonable accommodation, and it is governed by HUD's current guidance, FHEO-2020-01 (issued January 28, 2020). Key rules landlords miss: you may not charge a pet deposit, pet fee, or pet surcharge for an assistance animal, because it is not a pet. Breed and weight restrictions in your pet policy do not apply. You may require documentation of the disability-related need when the disability or the need is not obvious, and the tenant remains responsible for any actual damage the animal causes. You may deny a specific animal only if it poses a direct threat to others' health or safety, or would cause substantial physical damage, that cannot be reduced by reasonable means - and that judgment must be based on the individual animal's conduct, not its breed or your assumptions. Pennsylvania's PHRA separately protects guide and support animal users, so a wrongful denial can trigger both federal and state liability.
The duty is real but not unlimited. You may deny a request when: there is no disability-related nexus (the change is not connected to a disability); the request imposes an undue financial or administrative burden; it would fundamentally alter the nature of your operation; or it poses a direct threat that cannot be mitigated. Cost alone rarely wins for a landlord in private housing because the tenant usually pays for modifications - so an outright refusal is hard to justify. Before denying, complete the interactive process and offer any workable alternative in writing. If a tenant believes you denied them unlawfully, they can file with the Pennsylvania Human Relations Commission within 180 days (43 P.S. 951-963) or with HUD within 1 year under the FHA. After a PHRC complaint is docketed, it is served on the landlord within 30 days, and you must answer within 60 days of service. A denial you cannot document and justify is where liability begins.
This statute is generally enforced in public-accommodation contexts (restaurants, retail) rather than as part of a landlord-tenant dispute. For housing, the practical landlord defense against a fraudulent ESA claim is to require reliable documentation from a healthcare professional with a therapeutic relationship to the tenant, not to attempt criminal enforcement.
The most common mistake in Pennsylvania reasonable-accommodation cases is responding with a flat denial, "no pets means no pets", instead of engaging in the interactive process. The interactive process is itself a substantive duty. A landlord who refuses to consider the request, demands more than HUD permits, or imposes a pet fee on an assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied.
Reasonable modification (42 U.S.C. § 3604(f)(3)(A)) is a structural change, a grab bar, a ramp, lowered cabinets. The tenant pays. The landlord must permit the modification and may require restoration to original condition at move-out (except for changes that would not significantly affect re-rental). Reasonable accommodation is a change to a rule or policy. The landlord pays no out-of-pocket cost; the cost is administrative. Pennsylvania follows the federal rule.

No. The Pennsylvania Human Relations Act (43 P.S. 951-963) imposes the same core duties as the FHA - reasonable accommodations to policies and reasonable modifications to the space - and does not add a stronger who-pays rule or a different process. Its main added feature is explicit protection for tenants who use a guide or support animal. In practice you comply with both by following the federal standard.
In private, unsubsidized housing the tenant pays. Under 42 U.S.C. 3604(f)(3)(A) you must permit a reasonable structural modification, but the cost falls on the tenant, and you may require them to restore the interior at move-out, reasonable wear and tear excepted. In federally subsidized housing covered by Section 504, the provider pays unless it is an undue burden.
No. Under HUD guidance FHEO-2020-01, an assistance animal is not a pet, so you may not charge a pet deposit, pet fee, or surcharge, and your breed or weight limits do not apply. The tenant is still responsible for any actual damage the animal causes.
If the disability or the disability-related need is obvious, you cannot demand paperwork. When either is not obvious, you may request documentation confirming the disability and the need for the accommodation - typically a letter from a treating provider - but you cannot demand a diagnosis, medical records, or a specific form.
There is no fixed statutory day-count, but you must respond promptly through a good-faith interactive process. An unreasonable delay or a failure to respond is treated as a denial and can itself be discrimination. Reply in writing and, if the exact request is burdensome, offer an equally effective alternative.
You may deny when there is no disability-related nexus, when the request is an undue financial or administrative burden, when it would fundamentally alter your operation, or when it poses a direct threat to others' health or safety that cannot be reduced by reasonable means. Complete the interactive process and document your reasoning first.
A tenant can file with the Pennsylvania Human Relations Commission within 180 days of the denial (43 P.S. 951-963) or with HUD within 1 year under the Fair Housing Act. After a PHRC complaint is docketed it is served on you within 30 days, and you must answer within 60 days of service.
