Gas leak (natural gas or LPG) lead by count. Building fires lead by dollars. Together the top five categories make up about 57% of all calls.
Aug peaks. Feb dips. Watch for the typical fall climb starting in October.
18,362 incidents 2021–2025. Peak year was 2025. $204.5M cumulative property loss. 26 civilian deaths.
| Year | Incidents | YoY | |

| 2024 | 4,245 | +20.5% | |
| 2025 | 4,865 | +14.6% |
* Well below Milwaukee'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.
For the 623 building fires Milwaukee departments responded to in 2025, here's how they were classified once investigators were finished.

Top 10 ZIP codes by NFIRS incident count across 2021–2025. Each ZIP has its own fire profile — dive in for neighborhood-level context.
5 departments report to NFIRS for incidents in Milwaukee.
A 30-minute weekend can cut your home's exposure substantially. These four checklists are a good starting point.
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.
