Rapid City, SD Building Safety: Door Locking Hardware (2026)

Section 15.14.230 of the Rapid City Municipal Code amends IPMC Section 304.18, Building security, requiring that doors, windows, and hatchways serving dwelling units, rooming units, or housekeeping units carry devices designed to secure the occupants and property, tied to the egress rules in Section 702.3. The specific deadbolt standard sits in 304.18.1: any door providing access to a rented, leased, or let unit needs a deadbolt with a minimum 1-inch (25 mm) throw, and that deadbolt must be readily openable from the egress side without a key, special knowledge, or effort, so tenants are never locked in during an emergency.

The code specifically disqualifies a sliding bolt as an acceptable substitute for the deadbolt, and it requires the lock to be installed to the manufacturer's specifications and kept in good working order, not merely present at move-in. Section 304.18.2 extends the security standard to operable windows, which must carry a window sash locking device, and Section 304.18.3 covers basement hatchways serving a rented unit, which must be equipped with devices that keep out unauthorized entry. Because these standards sit inside the adopted Property Maintenance Code, enforcement runs through Chapter 15.14's notice-and-correction process: a code official documents the missing or noncompliant hardware, issues written notice under Sections 107.2 and 107.3, and gives the owner a correction period before penalties under Section 107.5 apply.
