A reasonable accommodation is a change to a rule, policy, or practice that a landlord makes so a tenant with a disability can use and enjoy the home on equal footing with everyone else. The classic example is waiving a no-pets policy for an assistance animal, but the same idea covers a reserved parking spot near the door, permission to pay rent on a date that matches a benefits deposit, or letting a caregiver have a key.
The duty comes from federal fair housing law and applies to nearly every small landlord. An accommodation is “reasonable” when it does not impose an undue financial or administrative burden and does not fundamentally change the way you operate.
In practice
Say you own a duplex and your lease charges a $35 monthly pet fee plus a $300 pet deposit. A tenant gives you a note from a licensed provider stating she needs an assistance animal for a disability. Because that animal is treated as an accommodation and not a pet, you do not get to apply the pet fee or the pet deposit. You forgo $35 a month, which is $420 over a year, plus the $300 deposit you would otherwise have held.
What does not change: the tenant still owes the same base rent, and she is still responsible for any actual damage the animal causes, which you can deduct from the ordinary security deposit at move-out the same as any other damage. The accommodation removes the surcharge, not the accountability.
Why it matters to a small landlord
The numbers are small, but the exposure is not. Denying or fumbling a request can turn a $420 fee into a fair housing complaint, so the safe move is to treat every request seriously, respond in writing, and keep the paper. If you find yourself wanting to capture an animal-related charge, read how pet rent actually works first, because the line between a pet and an assistance animal is exactly where landlords slip. When you do grant a request, put the terms in a written lease addendum so both sides know what was agreed and you have a record if anything is questioned later.
Reasonable accommodation lives inside the broader Fair Housing Act, which is the statute that creates the duty in the first place. It pairs closely with a lease addendum as the document that memorializes what you allowed, and it most often collides with a pet rent policy, the one charge you have to set aside for a qualified assistance animal.
