Full Breakdown
Olathe added Section 1031 (Physical Security) to its building code to make new construction resistant to unlawful entry, and it applies to all new residential structures plus alterations, additions, and repairs covered by the Existing Building Code (§15.02.370, 1031.1.1). Door hardware rules in 1031.4 cover hinges, strike plates, escutcheon plates, and locks. The lock provision, 1031.4.4, requires a single-cylinder deadbolt with minimum projection and pin-tumbler specs, or an equivalent lock meeting the same ANSI Grade 2 standard. Companion sections require secondary locks on sliding glass doors (1031.2.5) and a 180-degree door viewer on main entry doors (1031.4.5).
Violations & Fines
Doors that don't meet the hardware specification can fail the required rough-in or final inspection, holding up the permit and Certificate of Occupancy until corrected; the Building Codes Division enforces the standard.
