San Bernardino County enforces California Building Code rules requiring egress doors to unlock with a single motion from the inside. Deadbolts must release with the same handle action, and key-operated locks are restricted to specific Group A, B, M, and E uses.
CBC sections 1010.1.9 and R311 require egress doors to be readily openable from the inside without a key, special knowledge, or effort beyond a single motion. Double-cylinder deadbolts that need a key from inside are prohibited on residential primary egress. Public-facing businesses may use key locks only when occupied with proper signage. Childcare and assembly facilities face additional panic-hardware requirements. Building and Safety inspects during permit close-out and tenant improvements throughout unincorporated areas and contract inspection cities.
Failed final inspection, refused certificate of occupancy, and code-compliance citations for non-residential properties. Insurance claim denial is common after incidents involving non-compliant locks.
