§ 15-125. Doors.

(a)

All exposed edges of the lower eight (8) inches of wooden doors and door jambs, serving as entrances into business buildings from the ground, basement or cellar floors, and other doors accessible to rats, shall be protected against the gnawing of rats by covering such doors and jambs with solid sheet metal of not less than twenty-four-gauge thickness. The same material shall be used on doorsills or thresholds; or such doorsills or thresholds may be constructed of cement, stone, steel or cast iron.

(b)

Doors, door jambs and sills of coal chutes and hatchways that are constructed of wood shall be covered with solid sheet metal of twenty-four-gauge or heavier, or such chutes may be replaced with metal chutes of twenty-four-gauge or heavier, installed in such manner as will prevent the ingress of rats.

(c)

All doors on which metal flashings have been applied shall be properly hinged to provide for free swinging. When closed, doors shall fit snugly so that the maximum clearance between any door, jamb and sill shall not be greater than three-eighths of an inch.

(d)

Door jambs and sills constructed of metal, concrete, masonry, stone or cement mortar, or cast iron and steel, when fitting closely to exclude rats, are not required to comply with this section.
