ADA vs residential bathrooms: which rules apply in your home?
Direct answer: The ADA does not govern the private part of a house. Your own bathroom can be built to whatever works for you. Federal rules reach homes in narrower ways: the Fair Housing Act requires reinforced bathroom walls and usable bathrooms in multifamily buildings first occupied after March 13, 1991, and Section 504 requires accessible units in federally assisted housing.
Why people mix these up
Product listings use "ADA" loosely, and a contractor may say a tub is "ADA" when they mean it has a seat and a grab bar. The 2010 ADA Standards are a legal document with exact numbers, and they apply to particular buildings. Knowing which set of rules applies to your address tells you when those numbers are mandatory and when they are simply a helpful reference.
The four rule sets, side by side
| Rule | Where it applies | What it means for the tub or shower |
|---|---|---|
| ADA (2010 Standards) | Public accommodations, commercial facilities and state and local government buildings. Not the residential part of a private home (28 CFR 36.207). | Full tub and shower rules in sections 607 to 610, including the seat, grab bars and clearances. See our ADA bathtub requirements page. |
| Fair Housing Act design rules | "Covered multifamily dwellings" first occupied after March 13, 1991: all units in buildings of 4 or more units with an elevator, and ground-floor units in other buildings of 4 or more units (24 CFR 100.201 and 100.205). | Reinforced walls so grab bars can be added later around the toilet, tub, shower and shower seat, and a bathroom a wheelchair user can maneuver in. Grab bars are not required. |
| Section 504 of the Rehabilitation Act | Multifamily housing projects that receive federal financial assistance (24 CFR 8.22). | At least 5 percent of units, or one unit if that is more, must be accessible for people with mobility impairments, plus 2 percent for people with hearing or vision impairments. |
| State and local building codes | Set by your state or city, usually based on the International Building Code. | The model code's accessibility chapter exempts detached one- and two-family houses, but states and cities can add their own requirements. Your building department can tell you what was adopted. |
The ADA and private homes
The Justice Department's Title III rule spells this out. When a business such as a home-based therapy practice operates in a house, the part used only as a residence is not covered; only the areas used for the business, and the routes to them, are (28 CFR 36.207). A home bathroom used only by the family is outside the ADA, whatever size or age the house is.
The ADA Standards themselves recognize the difference. In residential dwelling units, grab bars may be left off a tub or shower if the walls are reinforced to take them later (607.4 and 608.3 exceptions), and a transfer shower in a dwelling unit can skip the seat if the wall is reinforced for one (608.4). A hand-held shower is still expected in residential units (608.6).
The Fair Housing Act in apartments and condos
The Fair Housing Act's design and construction rule has seven parts, and two of them touch the bathroom. The regulation at 24 CFR 100.205 requires "reinforcements in bathroom walls to allow later installation of grab bars around the toilet, tub, shower, stall and shower seat, where such facilities are provided," and "usable kitchens and bathrooms such that an individual in a wheelchair can maneuver about the space."
That is a much lighter standard than the ADA's. It does not require a tub seat, specific grab bar heights or a hand shower. What it does guarantee in a newer covered building is solid backing in the walls, which makes adding bars, a fold-down seat or a new tub surround much easier. HUD's Fair Housing Act Design Manual shows acceptable layouts.
Renting? The Fair Housing Act also lets a tenant with a disability make reasonable modifications to a unit, generally at the tenant's own cost. Put the request in writing, describe the work and who will do it, and keep a copy. A landlord may, where reasonable, ask that the interior be restored when you move out, and may ask for assurance that the work will be done properly and with any required permits (24 CFR 100.203).
Section 504 in federally assisted housing
If you live in public housing or a building funded with federal money, Section 504 applies. HUD's rule at 24 CFR 8.22 requires at least 5 percent of the units in a multifamily project, or at least one unit, to be accessible for people with mobility impairments. If you need one of those units, ask the housing manager how to request it; the accessible units are often where you will find a roll-in shower or a tub with a seat and full grab bars.
What this means when you plan a tub at home
- Design for the bather, not for a code inspector. In a single-family home, the right tub is the one the person can get into safely, with or without help. A wheelchair transfer tub that is not described anywhere in the ADA may be the better answer. See the transfer tub guide.
- Borrow the ADA numbers that solve real problems. A 30-inch strip of clear floor beside the tub, a seat top 17 to 19 inches high, bars rated for 250 pounds and water capped at 120°F are all worth copying.
- Get blocking in the walls. Even where no rule requires it, reinforcement behind the tub lets you add or move grab bars as needs change.
- Check permits. Moving plumbing or adding a dedicated circuit for a jetted or heated tub usually needs a local permit, separate from any accessibility rule.
- Bring in an occupational therapist. An OT home visit turns general rules into measurements for one person. VA and Medicaid programs often ask for that assessment before they pay for work, as our funding guide explains.
For a facility that must meet the ADA, such as a care home, clinic or hotel, Aging Safely Baths has a separate commercial quote process. For a house, the residential quote form or the form below works.
Questions people ask us
Does my bathroom at home have to be ADA compliant?
No. The ADA covers places of public accommodation and government facilities. Under 28 CFR 36.207, the part of a house used only as a residence is not covered, even if a business operates in another part of it. You can build the bathroom that suits the person using it.
What does the Fair Housing Act require in an apartment bathroom?
For covered multifamily buildings first occupied after March 13, 1991, the bathroom walls must be reinforced so grab bars can be added around the toilet, tub, shower and shower seat, and the bathroom must let a wheelchair user maneuver. Grab bars themselves are not required.
Can a landlord refuse to let me install grab bars or a walk-in tub?
Under the Fair Housing Act, a housing provider generally must allow reasonable modifications a tenant with a disability needs, usually at the tenant's expense, and in some cases may ask that the unit be restored when the tenant leaves. Ask in writing and keep a copy.
Is an "ADA tub" the best choice for a home?
Not always. A code-style tub still asks the bather to lift their legs over the rim from a seat or transfer board. Many wheelchair users find a transfer tub with an outward-swinging door easier, even though the ADA text does not describe that kind of tub.
