Boulder requires automatic fire sprinklers in most new multifamily, commercial, and large single-family structures under its locally amended International Fire Code. Wildland-urban interface zones add stricter triggers tied to defensible space and access.
BRC Title 10 adopts the International Fire Code and International Building Code with Boulder amendments that lower sprinkler thresholds compared to the state minimum. New apartment and condo buildings, hotels, dorms (including CU-Boulder), and many commercial occupancies require NFPA 13 or 13R systems. Larger single-family homes and homes in mapped wildland-urban interface zones often require NFPA 13D residential sprinklers, especially since Marshall Fire reforms. Boulder Fire Rescue plan review issues sprinkler permits, and certified contractors must perform annual inspection, testing, and maintenance per NFPA 25.
Permit denial or stop-work orders for missing sprinkler plans; certificate-of-occupancy hold; ITM violations cited by BFR fire prevention with reinspection fees.
