Each exterior door shall be secured as follows, where not prohibited by the building code:
A.
Single doors shall be equipped with a single cylinder deadbolt with a turnpiece with a minimum throw of one inch. A hook or expanding bolt may have a throw of three-quarters inch. A deadbolt must contain an insert of hardened steel to resist attempts at cutting through the bolt.
B.
On pairs of doors, the active leaf shall be equipped with the type lock required for a single door as in subsection A of this section. The inactive leaf shall be equipped with flush bolts protected by hardened material, with a minimum throw of five-eighths inch at the top and bottom.
C.
Cylinders shall be so designed or protected with cylinder guards that they cannot be gripped by pliers or other wrenching devices.
D.
Rolling overhead doors, solid overhead swinging, sliding or accordion-type doors shall be equipped with a cylinder lock or padlock when not controlled by electric power operation. Mounting screws for the lock case shall be inaccessible from the outside. A lock bolt shall be of hardened steel or have hardened-steel inserts. The lock bolt shall engage the strike sufficiently to prevent its being disengaged by any possible movement of the door within the space or clearances provided for installation and operation. If a padlock is used it shall have a minimum of one-quarter-inch diameter hardened-steel shackle and hardened-steel hasp attached by bolts which are nonremovable from the exterior.
E.
Metal accordion-grate or grille-type doors shall be equipped with metal guide-track at top and bottom, and a cylinder lock and/or padlock with hardened-steel shackle and minimum five-pin tumbler operation with nonremovable key when in an unlocked position. The bottom track shall be so designed that the door cannot be lifted from the track when the door is in a locked position.
F.
Outside pin-type hinges on all exterior doors shall be provided with nonremovable pins and shall have jamb pins which project through both hinge leaves and prevent removal of the door if the pin is removed from the hinge. Jamb pins shall be not less than three-sixteenths-inch diameter steel and shall project into the door and jamb not less than one-quarter inch. Jamb pins are not required for hinges which are shaped to prevent removal of the door when the hinge pin is removed.
G.
Glazed panels in doors or adjacent to the door frame shall be of approved, burglary-resistant material.
H.
Sliding glass doors shall have an approved auxiliary locking device added to the primary locking system to provide additional security when in the closed position. Such auxiliary locks shall have a minimum five-sixteenths-inch diameter bolt with a one-half-inch throw. The bolt shall engage the strike sufficiently to prevent its being disengaged by any possible movement of the door within the space or clearances provided for its installation and operation.
I.
Door jambs shall be constructed or protected to prevent violation of the function of the strike.
J.
All strike-plate areas shall be of material designed to maintain the effectiveness of the locking bolt strength.
K.
Sliding doors shall be designed to prevent removal by lifting while in a closed or partially open position.
L.
Exterior doors shall be illuminated with a minimum of one footcandle of light at the door. Lights shall be protected from breakage or tampering.
