5.5 Accessibility & Regulatory Compliance

Key Takeaways

  • ADA Title III regulates places of public accommodation and commercial facilities, requiring newly designed and constructed buildings to comply with 2010 ADA Standards for Accessible Design.
  • The Fair Housing Act Accessibility Guidelines (FHAAG) govern covered multifamily dwellings of 4 or more units, establishing 7 mandatory design features for accessibility.
  • Readily achievable barrier removal applies to existing Title III facilities, mandating the removal of architectural barriers where easily accomplishable without much difficulty or expense.
  • Universal Design expands beyond minimum legal compliance to create environments usable by all people to the greatest extent possible without adaptation or specialized design.

Accessibility & Regulatory Compliance

Architectural practice requires strict adherence to federal civil rights laws and regulatory accessibility standards. Ensuring that environments are accessible to individuals with disabilities is both a legal mandate and a fundamental ethical duty. Candidates preparing for the ARE 5.0 Practice Management exam must clearly understand the distinctions between the Americans with Disabilities Act (ADA) Title III, the Fair Housing Act Accessibility Guidelines (FHAAG), and the overarching design philosophy of Universal Design.


ADA Title III: Public Accommodations and Commercial Facilities

The Americans with Disabilities Act (ADA) is a federal civil rights law, not a local building code. Title III of the ADA prohibits discrimination on the basis of disability in the full and equal enjoyment of places of public accommodation (e.g., hotels, restaurants, retail stores, private schools, medical offices) and commercial facilities (e.g., office buildings, factories, warehouses).

Key ADA Title III Compliance Scope

  • New Construction: All newly designed and constructed places of public accommodation and commercial facilities must be readily accessible to and usable by individuals with disabilities in strict accordance with the 2010 ADA Standards for Accessible Design.
  • Alterations: When an existing building undergoes alterations, the altered areas must comply with accessible standards. Additionally, up to 20% of the cost of the primary alteration must be spent on providing an accessible "path of travel" (including accessible routes, restrooms, telephones, and drinking fountains) serving the altered area.
  • Readily Achievable Barrier Removal: Owners of existing places of public accommodation must remove architectural barriers where such removal is readily achievable—defined as easily accomplishable and able to be carried out without much difficulty or expense.

Barrier Removal Priorities for Existing Buildings

The Department of Justice recommends a four-tier priority system for readily achievable barrier removal in existing public accommodations:

  ┌─────────────────────────────────────────────────────────┐
  │               PRIORITY 1: ACCESSIBLE APPROACH           │
  │ Accessible parking, curb ramps, entrance ramps,         │
  │ accessible main entrance doors.                         │
  └───────────────────────────┬─────────────────────────────┘
                              │
                              ▼
  ┌─────────────────────────────────────────────────────────┐
  │               PRIORITY 2: ACCESS TO GOODS               │
  │ Accessible routes inside, aisle widths, accessible      │
  │ service counters, display heights.                      │
  └───────────────────────────┬─────────────────────────────┘

  │ Door clear width, grab bars, turning space, compliant   │
  │ lavatories and flush controls.                          │
  └───────────────────────────┬─────────────────────────────┘
                              │

  ┌─────────────────────────────────────────────────────────┐
  │               PRIORITY 4: OTHER MEASURES                │
  │ Drinking fountains, public telephones, visual alarms.   │

Fair Housing Act Accessibility Guidelines (FHAAG)

While ADA Title III governs public and commercial spaces, the Fair Housing Act (FHA) governs residential multifamily housing. The Fair Housing Act Accessibility Guidelines (FHAAG) apply to covered multifamily dwellings designed and constructed for first occupancy after March 13, 1991.

Covered Multifamily Dwellings Scope

  • All dwelling units in buildings containing 4 or more units if the building has an elevator.
  • All ground-floor dwelling units in buildings containing 4 or more units without an elevator.

The 7 Mandatory FHAAG Design Requirements

  1. Accessible Building Entrance on an Accessible Route: At least one building entrance must be on an accessible route.
  2. Accessible Public and Common Use Areas: Lobbies, clubhouses, laundry rooms, and parking must be accessible.
  3. Usable Doors: All doors designed to allow passage into and within all rooms must be wide enough (minimum 32 inches clear width).
  4. Accessible Route Into and Through the Covered Unit: Thresholds must not exceed 1/2 inch (beveled); interior corridors must provide adequate width.
  5. Light Switches, Outlets, and Thermostats in Accessible Locations: Switches and controls must be placed within accessible reach ranges (15 to 48 inches above finished floor).
  6. Reinforced Walls for Grab Bars: Bathroom walls must feature structural blocking/reinforcement to allow future installation of grab bars around toilets and tubs.
  7. Usable Kitchens and Bathrooms: Clear floor space must allow maneuvering room for individuals in wheelchairs.

Universal Design Principles

Universal Design moves beyond minimum legal code compliance to create products and environments that are inherently usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. Developed by Ronald Mace and the Center for Universal Design, the 7 Principles guide architectural practice:

  1. Equitable Use: Design useful and marketable to people with diverse abilities.
  2. Flexibility in Use: Accommodates a wide range of individual preferences and abilities (e.g., right- or left-handed operation).
  3. Simple and Intuitive Use: Easy to understand regardless of user experience, knowledge, or language skills.
  4. Perceptible Information: Communicates necessary information effectively through multi-sensory modes (visual, verbal, tactile).
  5. Tolerance for Error: Minimizes hazards and adverse consequences of accidental actions.
  6. Low Physical Effort: Designed to be used efficiently and comfortably with minimal fatigue.
  7. Size and Space for Approach and Use: Appropriate size and space provided for approach, reach, manipulation, and use regardless of user's body size, posture, or mobility.
