What the Fire Coverage Data Means for Jefferson County, CO
Jefferson County reports 34 fire departments in the federal HIFLD registry, staffed by approximately 1,331 total personnel. The organizational breakdown matters because career, volunteer, and combination departments differ sharply in response time, funding, and training cadence: this county lists 3 career (paid), 9 volunteer, and 9 combination departments. 22 of these departments also provides Emergency Medical Services, meaning the same crews that arrive on a structure fire can often begin patient care on cardiac or trauma calls without waiting for a separate ambulance agency.
Benchmarking the county against its parent state highlights coverage gaps and strengths. Colorado overall averages roughly 26 personnel per department across 575 departments. Jefferson County averages 39 personnel per department, 50% above the state mean. Heavier staffing usually signals higher population density, more commercial risk, or county-wide mutual aid consolidation. The state reports about 29,000 fires and 55 fire deaths annually, and 41% of its departments are volunteer-run.
Residents, property owners, and insurance agents can use this profile in several practical ways. A home inside a career or combination department's first-due area typically earns better ISO Public Protection Classification ratings and lower homeowners premiums than one served solely by a distant volunteer station. If the county is heavily volunteer, it is worth checking whether the nearest department has recent FEMA AFG or SAFER grants and whether mutual-aid agreements extend coverage during large incidents. Click into any department below to see its specific personnel count, station footprint, apparatus inventory, EMS status, and FEMA grant history. All figures come from HIFLD Open Data (FEMA/DHS) and USFA published fire statistics; small volunteer departments are sometimes underreported, so treat zero-value fields as missing data rather than absent services.
