HomeMy WebLinkAboutA00-41 - ACCESSIBILITY ANALYSIS AND DETAILSA."CODE TYPE A" AND "CODE TYPE B" DETAILS APPLY TO ALL RESIDENTIAL UNITS AND ARE BASED ON IBC,
ANSI 117.1, AND FHA REQUIREMENTS.
B. "PUBLIC" DETAILS APPLY TO PUBLICLY ACCESSIBLE SPACES INCLUDING LEASING, AMENITY, COURTYARD,
AND RETAIL SPACES AND ARE BASED ON IBC AND 2010 ADA.
Specification A
If Specification A is used it applies to all bathrooms, and all fixtures in those bathrooms must be usable.
Specification B
If Specification B is used, it applies to one bathroom, and only one of each type of fixture must be usable; additional bathrooms
in the unit are exempt only from maneuvering and clear floor space requirements at fixtures.
Usable bathroom specifications include:
1. an accessible route to and into the bathroom with a nominal 32-inch clear door opening (Requirements 3 and 4),2. switches, outlets, and controls in accessible locations (Requirement 5),
3. reinforced walls to allow for the later installation of grab bars around the toilet, tub, and shower stall; under certain conditions
provisions for reinforcing must be made in shower stalls to permit the installation of a wall-hung bench seat (Requirement 6),
4. maneuvering space within the bathroom to permit a person using a mobility aid to enter the room, close and reopen the door,
and exit (Requirement 7), and5. maneuvering and clear floor space within the bathroom to permit a person using a mobility aid to approach and use fixtures;
fixture dimensions and placement are specified only under certain conditions (Requirement 7).
Bathroom Requirements for Covered Dwelling Units
All bathrooms as defined in the Guidelines must:
1. be on an accessible route (Requirement 4),
2. have 32-inch nominal clear width doorways (Requirement 3),
3. have switches, outlets, and controls in accessible locations (Requirement 5),
4. have reinforcing around toilets, tubs, and showers (Requirement 6), and
5. meet Requirement 7, Specification A or B:
Specification A
If Specification A is used it applies to all bathrooms, and all fixtures in those bathrooms must be usable.
Specification B
If Specification B is used, it applies to one bathroom, and only one of each type of fixture must be usable; additional
bathrooms in the unit are exempt only from maneuvering and clear floor space requirements at fixtures.
Powder Room Requirements for Covered Dwelling Units
Powder rooms must:
1. be on an accessible route (Requirement 4),
2. have 32-inch nominal clear width doorways (Requirement 3), and
3. have switches, outlets, and controls in accessible locations (Requirement 5).Exception
When the powder room is the only toilet facility on the entry level of a multi-story unit in a building with one or more
elevators, it must, in addition to Requirements 3, 4, and 5, meet the reinforcing specifications of Requirement 6 and
the maneuvering and clear floor specifications of Requirement 7.
Maximum Allowable Height Difference Between Interior Floor Level and Exterior Floor Level
level difference at primary entry door:
0'' pervious construction (e.g., wood decking with spaces)
1/2'' impervious construction (e.g., concrete, brick, or flagstone)
level difference at secondary door:
1/2'' pervious construction
4'' impervious construction
Walks on Accessible Routes
Walks that are part of accessible routes become ramps when their slope exceeds 5% (1 in 20). Handrails are not required on
walks with slopes between 0% and 5%, but they are required on those steeper than 5% and up to 8.33% (1 in 12). Slopes
steeper than 8.33% are not usable by most people with disabilities and cannot be considered part of an accessible route.Handrail requirements for walks differ, depending upon which buildings the walks connect. This is addressed in the following
sections.
