Car and van parking spaces shall have an adjacent access aisle complying with Section 502.4.
Access aisles shall be marked so as to discourage parking in them and be provided with the designation "no parking." The "no parking" designation shall be provided on a sign centered at the head end of the access aisle a maximum of 96 inches (2440 mm) from the head of the access aisle, and be mounted 60 inches (1525 mm) minimum and 66 inches (1676 mm) maximum above the floor of the access aisle, measured to the bottom of the sign. Where access aisles are marked with lines, the width measurements of access aisles and adjacent parking spaces shall be made from the centerline of the markings.
A vertical clearance of 98 inches (2490 mm) minimum shall be provided at the following locations:
Accessible parking spaces shall be identified by signs complying with Minnesota Statutes, Section 169.346, and include the International Symbol of Accessibility complying with Section 703.6.3.1. Where all accessible parking spaces do not provide a minimum vertical clearance of 98 inches (2490 mm), signs identifying van parking spaces shall contain the designation "van accessible." Signs shall be centered at the head end of the parking space a maximum of 96 inches (2440 mm) from the head of the parking space, and be mounted 60 inches (1525 mm) minimum and 66 inches (1676 mm) maximum above the floor of the parking space, measured to the bottom of the sign.
Exception: Parallel parking spaces shall have a sign located on the side, at the head end of the parking space.
Passenger loading zones shall have an adjacent access aisle complying with Section 503.3.
A vertical clearance of 114 inches (2895 mm) minimum shall be provided at the following locations:
All steps on a flight of stairs shall have uniform riser height and uniform tread depth. Risers shall be 4 inches (100 mm) minimum and 7 inches (180 mm) maximum in height. Treads shall be 11 inches (280 mm) minimum in depth.
The radius of curvature at the leading edge of the tread shall be 1/2 inch (13 mm) maximum. Nosings that project beyond risers shall have the underside of the leading edge curved or beveled. Risers shall be permitted to slope under the tread at an angle of 30 degrees maximum from vertical. The permitted projection of the nosing shall be 11/2 inches (38 mm) maximum over the tread or floor below.
Handrails shall be continuous within the full length of each stair flight or ramp run. Inside handrails on switchback or dogleg stairs or ramps shall be continuous between flights or runs. Other handrails shall comply with Sections 505.10 and 307.
Exception: Handrails shall not be required to be continuous in aisles serving seating where handrails are discontinuous to provide access to seating and to permit crossovers within the aisles.
Clearance between handrail gripping surface and adjacent surfaces shall be 11/2 inches (38 mm) minimum.
Gripping surfaces shall be continuous, without interruption by newel posts, other construction elements, or obstructions.
Handrails shall extend beyond and in the same direction of stair flights and ramp runs in accordance with Section 505.10.
At the top of a stair flight, handrails shall extend horizontally above the landing for 12 inches (305 mm) minimum beginning directly above the landing nosing. Extensions shall return to a wall, guard, or the landing surface, or shall be continuous to the handrail of an adjacent stair flight.
At the bottom of a stair flight, handrails shall extend at the slope of the stair flight for a horizontal distance equal to one tread depth beyond the bottom tread nosing. Extensions shall return to a wall, guard, or the landing surface, or shall be continuous to the handrail of an adjacent stair flight.
