Full Breakdown
Chino Municipal Code § 15.48.070(A), adopted by Ord. 2022-015 (7-19-2022), sets residential door-hardware standards on top of the general standards in § 15.48.060. Exterior swinging doors must be solid-core construction at least 1¾ inches thick (or panels at least 9/16 inch), and all swinging exterior doors and garage-to-house doors must carry a one-inch deadbolt lock with a minimum one-inch bolt throw, a steel insert, and a free-turning cylinder guard. Companion rules in the same section require a keyless main entrance, non-removable hinge pins, and a 180-degree door viewer on front doors. Commercial and industrial buildings follow a separate standard at § 15.48.080.

Failure to meet these standards blocks final inspection and certificate of occupancy under § 15.48.130; the building official won't sign off until the required hardware is installed.
