Type A
A higher level of accessibility and adaptability under ICC A117.1. Type A units generally require more usable clearances and features that support residents with mobility disabilities.
Type B
The baseline adaptable dwelling unit standard for covered multifamily housing. Type B focuses on usable routes and features that support later adaptation.
UFAS
The Uniform Federal Accessibility Standards are the technical design standards used for federally assisted housing under Section 504. They are the standard behind the familiar requirement that at least 5% of units be accessible to people with mobility disabilities and at least 2% to people with hearing or vision disabilities.
Universal design
A broader design approach that considers how spaces can work comfortably for people of all ages and abilities, and as circumstances change.
The right strategy may combine more than one of these approaches. They overlap, but they are not interchangeable.
Local incentives and development opportunities
Local jurisdictions may connect accessibility to zoning flexibility, additional floor area, affordability programs, tax exemptions, fee reductions, or funding priorities. Availability and eligibility vary.
For example, the City of Portland is developing a Housing Bonus Alignment Strategy that would let developers earn stackable land use bonuses for higher levels of accessibility. Other programs, such as system development charge exemptions and property tax programs, may be available based on affordability, tenure, location, or other project characteristics.
Accessibility alone does not automatically qualify a project. We research the current rules and help your team evaluate how accessibility fits within your full development strategy.
