In 2025, fire departments serving Alpharetta responded to 165 fire and hazmat incidents — from cooking fires to gas leaks to a single $18K building blaze. Here's the full picture.
Incomplete 2025 data. Alpharetta's departments reported 165 incidents to NFIRS for 2025, against about 343 in a typical year, so 2025 figures on this page undercount. The 2021–2025 totals are the better guide.
Gas leak (natural gas or LPG) lead by count. Building fires lead by dollars. Together the top five categories make up about 63% of all calls.
Jan peaks. May dips. Watch for the typical fall climb starting in October.
1,717 incidents 2021–2025. Peak year was 2023. $6.6M cumulative property loss.

* Well below Alpharetta's usual volume. That almost always means one or more departments didn't submit a full year to NFIRS, not that fires dropped, so no year-over-year change is shown for it.

Numbers reflect incidents reported by participating fire departments to the National Fire Incident Reporting System (NFIRS) Public Data Release for calendar year 2025. NFIRS is voluntary — about 23,000 of roughly 30,000 US fire departments report — so totals are a strong indicator, not a complete census. Per-capita comparisons use 2023 ACS population estimates. Wildland fire data complements NFIRS with NIFC and USFS perimeters. Active-fire counts come from a dated NIFC snapshot, not a live feed.
