Rule 24.301.905 - GUIDELINES FOR COMPLIANCE WITH REQUIREMENTS FOR EXTERIOR ACCESSIBLE ROUTE AND PARKING SPACE(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.Mont. Admin. r. 24.301.905
