In 2025, fire departments serving Lemon Grove responded to 19 fire and hazmat incidents — from cooking fires to gas leaks to a single $75K building blaze. Here's the full picture.
Incomplete 2025 data. Lemon Grove's departments reported 19 incidents to NFIRS for 2025, against about 61 in a typical year, so 2025 figures on this page undercount. The 2021–2025 totals are the better guide.
Outside rubbish fire, other lead by count. Building fires lead by dollars. Together the top five categories make up about 63% of all calls.
Feb peaks. Jun dips. Watch for the typical fall climb starting in October.
304 incidents 2021–2025. Peak year was 2021. $1.1M cumulative property loss.

* Well below Lemon Grove'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.
