Mississippi Code Title 43. Public Welfare § 43-6-103

(1) At least one (1) primary entrance to each building shall be accessible by individuals in wheelchairs from a point of vehicular arrival and such access shall be by means of a walk or walks at least forty-eight (48) inches wide and having a gradient not greater than five percent (5%), or eight and thirty-three one-hundredths percent (8.33%) with handrails. These walks shall be of a continuing surface, not interrupted by steps or abrupt changes in level. Wherever walks cross other walks, driveways, or parking lots they shall blend to a common level. A walk shall have a level platform at the top which is at least five (5) feet by five (5) feet, if a door swings out onto the platform or toward the walk. This platform shall extend at least one (1) foot beyond each side of the doorway. A walk shall have a level platform at least three (3) feet deep and five (5) feet wide, if the door does not swing onto the platform or toward the walk. This platform shall extend at least one (1) foot beyond each side of the doorway.

(2) Each building shall have at least one (1) primary entrance which is accessible to individuals in wheelchairs. In multi-story buildings, such primary entrance shall provide access to an elevator either on a level plane or by ramp.

Doors shall have a clear opening of no less than thirty-two (32) inches when fully open and shall be operable by a single effort. The floor on the inside and outside of each doorway shall be level for a distance of five (5) feet from the door in the direction the door swings and shall extend one (1) foot beyond each side of the door. Sharp inclines and abrupt changes in level shall be avoided at doorsills. As much as practicable, thresholds shall be flush with the floor.
