FHA Accessibility Guidelines: Seven Design Features and Safe Harbors

The Fair Housing Act’s accessibility guidelines require every residential building with four or more units designed for first occupancy after March 13, 1991, to be built with a defined set of accessibility features, from wheelchair-passable doorways to reinforced bathroom walls.¹ The features must be there whether or not any current resident has a disability, and civil penalties for a design violation can reach $131,308 per discriminatory practice.²

Which Buildings Have to Comply

The rules use the term “covered multifamily dwellings,” and they reach any residential building with four or more units designed and constructed for first occupancy after March 13, 1991.³ A building meets that timing test if it was actually occupied by that date or if the last building permit was issued on or before June 15, 1990.⁴

How much of the building must comply depends on the elevator. If a building has one or more elevators, every dwelling unit has to meet the accessibility requirements. If it doesn’t, only the ground-floor units must comply.⁵

“Ground floor” is broader than it sounds. A floor counts as a ground floor if it sits at a level with a building entrance on an accessible route. On sloped sites, a building can have more than one ground floor when multiple levels have grade-level entrances, which pushes up the number of units that must be built accessibly.³

Single-family homes, duplexes, and triplexes fall below the four-unit threshold and are not covered by the design and construction rules regardless of when they were built.¹ Older multifamily buildings, meaning those occupied before March 13, 1991, are also outside the design requirements, though the Fair Housing Act’s broader antidiscrimination protections still apply and residents can still request reasonable modifications.

The Seven Required Design Features

HUD organizes compliance around seven core features. Get each one right and the building meets the statutory requirements.

Accessible Building Entrance on an Accessible Route

Every covered building needs at least one entrance on an accessible route, a continuous, unobstructed path connecting the public street or sidewalk to the building’s interior.⁶ The guidelines don’t dictate how many entrances a building has, but at least one has to work for someone using a wheelchair.⁴

Accessible Common and Public Use Areas

Lobbies, rental offices, mailrooms, laundry facilities, swimming pool decks, fitness areas, playgrounds, and community rooms must all be accessible and connected to covered units by an accessible route.⁶

Parking has its own rules. At least two percent of the parking spaces serving covered units must be accessible and on an accessible route.⁷ If a development offers different parking types, such as surface lots, garages, and covered carports, at least one accessible space is required for each type even after the two-percent total is satisfied. Visitor parking is measured differently: the guidelines require a “sufficient” number of accessible visitor spaces to reach grade-level entrances rather than a fixed percentage.

Usable Doors

All doors intended for passage within a covered unit must provide a nominal 32 inches of clear width. That covers the front door, bedroom and bathroom doors, doors into walk-in closets and utility rooms, and secondary exterior doors onto balconies or patios.⁸ A tolerance of one-quarter to three-eighths of an inch is accepted because hinges, trim, and installation tolerances all cut into the opening.

Accessible Route Into and Through the Unit

Once inside, hallways and passages must be wide enough for a wheelchair user to move through comfortably. The route has to be continuous and free of abrupt level changes or pinch points that would force someone to back up or dismount.⁵

Reachable Environmental Controls

Light switches, electrical outlets, thermostats, and similar controls must sit where a seated person can reach them. HUD’s Design Manual specifies a mounting range of 15 to 48 inches above the floor when nothing sits between the user and the control. When a shelf or counter obstructs the reach, the maximum height drops depending on how far the obstruction extends from the wall.⁹

Reinforced Bathroom Walls

Bathroom walls must be structurally reinforced so grab bars can later be installed near the toilet, bathtub, and shower.³ The grab bars themselves don’t have to be there at move-in. What matters is that the framing or blocking behind the drywall is strong enough for a resident to add bars later without opening the wall. This is one of the cheapest features to build in and one of the most expensive to add after the fact.

Usable Kitchens and Bathrooms

Kitchens and bathrooms need enough floor space for a wheelchair user to approach and use every fixture and appliance. The rule calls for a 30-by-48-inch clear floor space at each appliance, fixture, and work surface, positioned parallel or perpendicular to the item and centered on it, and each clear space must connect to the accessible route through the kitchen.¹⁰

In U-shaped kitchens with the sink or cooktop at the base of the U, the space between opposing counters must be at least 60 inches wide so a wheelchair can turn. The exception: if the builder installs removable base cabinets under the sink or cooktop, the counter-to-counter width can drop to 40 inches, because pulling the cabinet later creates knee space. When removable cabinets are used, the walls and floor of the knee space have to be fully finished at initial construction, and any hot pipes or sharp edges under the sink must be insulated or enclosed from day one.

Bathrooms carry their own dimensions. The toilet’s center line must sit at least 33 inches from the nearest side wall or adjacent fixture. A 30-by-48-inch clear floor space is required at the lavatory, bathtub, and shower stall, and that space has to fall outside the swing of the door when it is closed.

Safe Harbors: The Cleanest Path to Compliance

HUD keeps a list of recognized building codes and technical standards called “safe harbors.” A builder who follows one of them is presumed to satisfy the design and construction requirements. HUD’s most recent additions were finalized in December 2020 with an effective date of March 8, 2021.¹¹

The current safe harbors fall into three groups:

Accessibility standards: ICC A117.1-2009, ICC/ANSI A117.1-2003, ICC/ANSI A117.1-1998, CABO/ANSI A117.1-1992, and ANSI A117.1-1986.
International Building Code editions: 2000, 2003, 2006, 2009, 2012, 2015, and 2018. The 2009 and later editions must be interpreted with their corresponding IBC Commentary.¹¹
HUD’s Fair Housing Act Design Manual, originally published in 1996 and reissued in 1998.

Following a safe harbor isn’t technically required, but it produces the strongest defense if a building’s compliance is challenged. A builder who deviates from a recognized standard carries the burden of showing the design meets every statutory requirement on its own.

What Existing Residents Can Request

The design rules apply when a building goes up. After that, two other tools cover residents with disabilities in any building, new or old.

A reasonable modification is a physical change to a unit or common area, like a ramp, a widened doorway, or grab bars. Under federal law, the tenant pays for the modification.⁵ A landlord can require the interior to be restored to its original condition on move-out, minus normal wear and tear, and can require that the work be done professionally, but cannot dictate which contractor is used or reject a modification on aesthetic grounds. If the property receives federal financial assistance, the housing provider generally pays for the modification rather than the tenant.¹²

A reasonable accommodation is a change to a rule, policy, or practice rather than a physical change. Allowing an assistance animal in a no-pets building is the standard example. The housing provider bears the cost of an accommodation because it typically involves adjusting a policy, not construction.¹²

When a disability is obvious and the need for the requested change is apparent, a housing provider cannot demand additional documentation. When neither is obvious, the provider may ask for enough information to verify that the person has a disability under the Act and that the request is related to it. A letter from a doctor, a peer support group, or proof of Social Security disability benefits can satisfy that, and any disability-related information the provider receives must be kept confidential.¹³

Penalties for a Design Violation

Accessibility failures are treated as discriminatory housing practices. In an administrative proceeding before HUD, civil penalties run on a three-tier scale tied to the respondent’s history:

No prior violations: up to $26,262 per discriminatory practice.
One prior violation within the past five years: up to $65,653 per practice.
Two or more prior violations within the past seven years: up to $131,308 per practice.²

These caps are adjusted for inflation periodically. Penalties apply per practice, not per building, so a single development with multiple accessibility failures can generate multiple separate penalties. An aggrieved individual can also file a private lawsuit in federal or state court, and courts can award actual damages, punitive damages, injunctive relief, and attorney’s fees.¹⁴ The Department of Justice can bring its own enforcement action. On top of penalties, retrofitting costs compound the exposure: reworking a kitchen that was built without proper clearances often means tearing out cabinetry and reconfiguring plumbing.

How to File a Complaint

Complaints go to HUD’s Office of Fair Housing and Equal Opportunity. You can file online at HUD’s housing discrimination portal, call 1-800-669-9777, or mail a printed form to your regional FHEO office.¹⁵ You’ll need your name and address, the person or entity you are filing against, the property, and a description of what happened.

The deadline for an administrative complaint with HUD is one year from the date of the last discriminatory act.¹⁶ If you skip the administrative route and file a private lawsuit instead, the statute of limitations is two years from the last discriminatory act.¹⁴ You can file a lawsuit whether or not you have also filed with HUD, though if HUD has already reached a conciliation agreement on your behalf, you generally cannot pursue a separate lawsuit on the same claims.
