Existing Buildings - Additional Exceptions and Equivalent Facilitation

This section outlines additional exceptions to accessibility requirements for existing buildings and explains the concept of equivalent facilitation—an alternative compliance pathway when full accessibility creates an unreasonable hardship.

Additional Project-Specific Exceptions

Beyond the general unreasonable hardship provisions outlined in Existing Buildings - General Concept and Requirements, the following exceptions apply to specific types of work:

Exception 3: Limited Alterations to Specific Building Elements

Alterations to the following building elements may be limited to the actual work of the project:

  • Entrances
  • Toilet facilities
  • Elevators
  • Steps & handrails

This exception applies when these alterations are made to meet accessibility requirements or the "readily achievable" requirements of Title III of the Americans with Disabilities Act.

Exception 4: Mechanical and Cosmetic Work

Projects consisting only of the following types of work are not subject to accessibility requirements:

  • Heating, ventilation, and air conditioning (HVAC)
  • Reroofing
  • Electrical work not involving placement of switches & receptacles
  • Cosmetic work that does not affect items regulated by this code, such as painting

These exemptions recognize that purely mechanical or cosmetic updates do not affect the accessibility of the facility.

Exception 5: Equivalent Facilitation

When an unreasonable hardship exists, the building official may grant an unreasonable hardship determination if equivalent facilitation is provided.

Equivalent facilitation allows alternative methods of compliance that achieve substantially equivalent or greater accessibility compared to strict code compliance.

Exception 6: Legal or Physical Constraints

These regulations shall not apply when legal or physical constraints would not allow compliance with accessibility regulations or equivalent facilitation without creating an unreasonable hardship as determined by an appeals process.

Understanding Equivalent Facilitation for Existing Buildings

Equivalent facilitation provides flexibility for existing building projects where full compliance creates significant challenges. The following technical specifications illustrate acceptable equivalent facilitation options for toilet room configurations.

Grab Bar Standards

All equivalent facilitation toilet room configurations must use grab bars meeting these specifications:

SECTION THROUGH TYPICAL GRAB BAR:
- 1-1/4" to 1-1/2" nominal diameter grab bar
- Wall mounting with proper clearance

Front Transfer Style Toilet Room

This configuration allows users to transfer from a wheelchair to the toilet from the front approach:

FRONT TRANSFER STYLE TOILET ROOM PLAN:
- Centerline of fixture alignment
- 18" min. clearance requirements
- 36" min. grab bar on side wall
- 24" min. grab bar behind toilet
- 32" min. clear floor space
- 48" min. depth measurement
- 60" min. clear turning space
- Flush activation on wide side (32" min. to edge of water closet)

Key measurements:

  • Minimum 60" clear turning diameter
  • Minimum 48" depth for maneuvering
  • Minimum 32" clear floor space adjacent to toilet
  • Grab bars: 36" minimum on side wall, 24" minimum behind toilet
  • Flush control located on the wide side (minimum 32" to edge of water closet)

Side Transfer Style Toilet Room

This configuration allows users to transfer from a wheelchair to the toilet from a side approach:

SIDE TRANSFER STYLE TOILET ROOM PLAN:
- Similar layout with side approach configuration
- 32" min. to edge of water closet
- 36" min. grab bar
- 24" min. grab bar
- 32" min. clear floor space
- 48" min. depth
- 60" min. clear turning diameter
- Flush activation on wide side

Key measurements:

  • Minimum 60" clear turning diameter
  • Minimum 48" depth for maneuvering
  • Minimum 32" clear floor space adjacent to toilet
  • Grab bars: 36" minimum on side wall, 24" minimum behind toilet
  • Flush control located on the wide side (minimum 32" to edge of water closet)

When to Consider Equivalent Facilitation

Equivalent facilitation options like the toilet room configurations shown above may be acceptable for existing buildings when:

  1. Full compliance with standard accessibility requirements creates an unreasonable hardship
  2. Physical constraints (such as limited space or existing structural elements) prevent standard configurations
  3. The alternative solution provides substantially equivalent accessibility

Obtaining Approval for Equivalent Facilitation

To use equivalent facilitation in your project:

  1. Document the specific constraint preventing full compliance
  2. Demonstrate how the proposed alternative provides equivalent or greater accessibility
  3. Submit your proposal to the building official for review and approval
  4. If denied, follow the appeals process outlined under Exception 6
