Administrative Rules of Montana › Department 24 - LABOR AND INDUSTRY › Chapter 24.301 - BUILDING CODES › Subchapter 24.301.9 - Building Accessibility Rules › Rule 24.301.905 - GUIDELINES FOR COMPLIANCE WITH REQUIREMENTS FOR EXTERIOR ACCESSIBLE ROUTE AND PARKING SPACE

Current through Register Vol. 13, July 5, 2024
(1) The following
				guidelines for providing an accessible exterior route and parking spaces are
				not inclusive of all means for achieving compliance but may be utilized to meet
				the established requirements:
(a) Width of
				route: 36 inches minimum.
(b)
				Length of route: The most direct route to the accessible building entrance with
				passing spaces of 60 inches x 60 inches provided at intervals not to exceed 200
				feet for routes with a clear width of less than 60 inches.
(c) Slope of route: The cross slope of a
				route (perpendicular to the direction of travel) shall not exceed 1:50 (1
				vertical to 50 horizontal). The maximum running slope (in the direction of
				travel) of a route may not exceed 1:20 (1 vertical to 20 horizontal) with
				portions of the route with running slopes steeper than 1:20 (1 vertical to 20
				horizontal) considered ramps. If the terrain precludes development of
				accessible routes with running slopes of 1:8 (1 vertical to 8 horizontal), it
				may be infeasible to develop accessible routes.
(d) Surface material: Surface texture of a
				route shall be stable, firm and slip-resistant, with all surface coverings
				securely attached. If carpet is used on the route it must have a firm cushion
				if a cushion is provided, and a maximum pile thickness of 1/2 inch. Other
				acceptable surface materials may include concrete, asphalt, wood and 3/8 inch
				minus crushed aggregate, with an acceptable bonding agent, compacted to a field
				density of 95% maximum dry density, which can be shown to be sufficiently
				durable to allow for snow removal and other maintenance activities without
				affecting surface stability, firmness or slip-resistance. The building official
				may approve alternate surface materials for accessible routes which will
				provide compliance with the requirements for surface texture.
(e) Vehicle parking space size per vehicle:
				108 inches minimum wide by 216 inches long and shall include 60 inches minimum
				access aisle. A van accessible parking space shall have a minimum of 96 inches
				access aisle width. Two accessible parking spaces may share a common access
				aisle.
(f) Vehicle parking space
				and access aisle slope: To be level with surface slopes not exceeding 1:50 (1
				vertical to 50 horizontal) in all directions.
(g) Signage requirements: Parking spaces
				shall be designated as reserved by a post or wall mounted sign showing the
				symbol of accessibility. Such signs shall be located so they cannot be obscured
				by a vehicle parked in the space and the sign shall be preferably located
				immediately adjacent to the designated space but no more than 10 feet from the
				designated space. The sign shall also indicate that a permit is required and
				state the penalty for a violation as established in
				49-4-302
				and
				49-4-307,
				MCA.
