Summary
Kansas City requires exterior dwelling doors to carry a single-cylinder deadbolt with a one-inch throw, a five-pin tumbler cylinder, and an ANSI Grade 2 rating, under the city's local amendments to the Building Code.
430.4.2 Locks. Swinging doors shall be provided with a single-cylinder deadbolt locking device (keyed on exterior only) with a minimum projection of one inch (1"). The deadbolt shall penetrate at least three-fourths inch (¾") into the strike receiving the projected bolt. The cylinder shall have a twist-resistant, tapered hardened steel cylinder guard. The cylinder shall have a minimum of five (5) pin tumblers... All deadbolts shall meet ANSI grade 2 specifications.

Full Breakdown
Under Section 430 of Kansas City's local amendments to the International Building Code (Sec. 18-40), every exterior door providing direct access into a dwelling unit, if reachable from grade, must have a single-cylinder deadbolt keyed only on the exterior side, with a bolt projection of at least one inch that penetrates three-fourths of an inch into the strike, a twist-resistant hardened cylinder guard, a minimum five-pin tumbler cylinder, and an ANSI Grade 2 rating overall. Sliding glass doors instead need a secondary pin or bolt lock. Vehicle access doors and storm or screen doors are exempt, and doors with integral multi-point locking devices are excepted from the deadbolt spec.
Violations & Fines
Doors that don't meet the Section 430 deadbolt, frame, or hinge specs fail the building official's inspection, which holds up permit sign-off and occupancy on new dwelling construction.
