In 2025, fire departments serving Sierra Madre responded to 17 fire and hazmat incidents . Here's the full picture.
Incomplete 2025 data. Sierra Madre's departments reported 17 incidents to NFIRS for 2025, against about 68 in a typical year, so 2025 figures on this page undercount. The 2021–2025 totals are the better guide.
Building fires lead by count. Building fires lead by dollars. Together the top five categories make up about 71% of all calls.
Jan peaks. May dips. Watch for the typical fall climb starting in October.
341 incidents 2021–2025. Peak year was 2022. $18K cumulative property loss.
| Year | Incidents | YoY | |

| 2022 | 123 | +38.2% | |

* Well below Sierra Madre'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 3 building fires Sierra Madre departments responded to in 2025, here's how they were classified once investigators were finished.
NFIRS Area of Origin (AREA_ORIG) for the 17 building fires investigators classified across 2021–2025. The room or location where ignition occurred — kitchens, bedrooms, exterior, vehicle areas — tells you where to focus prevention.
| # | Area of origin | Count | Share | |
|---|---|---|---|---|
| 1 | Cooking area, kitchen | 6 | 35.3% | |
| 2 | Outside area, other | 4 | 23.5% | |
| 3 | Bathroom, checkroom, lavatory, locker room | 2 | 11.8% | |
| 4 | Storage: supplies or tools; dead storage | 1 | 5.9% | |

| 6 | Exterior balcony, unenclosed porch | 1 | 5.9% | |
| 7 | Engine area, running gear, wheel area | 1 | 5.9% | |
| 8 | Open area - outside; included are farmland, field | 1 | 5.9% |
NFIRS Heat Source (HEAT_SOURC) — the physical thing that started it. Spark or ember from operating equipment, an open flame, smoking materials, or hot embers from a fireplace are the leading culprits nationwide. Here's the Sierra Madre mix.
| # | Heat source | Count | Share | |
|---|---|---|---|---|
| 1 | Heat from powered equipment, other | 2 | 11.8% | |
| 2 | Spark, ember or flame from operating equipment | 2 | 11.8% | |
| 3 | Radiated, conducted heat from operating equipment | 2 | 11.8% | |
| 4 | Arcing | 2 | 11.8% | |
| 5 | Heat, spark from friction | 2 | 11.8% | |
| 6 | Hot ember or ash | 1 | 5.9% | |
| 7 | Heat from undetermined smoking material | 1 | 5.9% | |
| 8 | Flame/torch used for lighting | 1 | 5.9% | |
| 9 | Chemical reaction | 1 | 5.9% | |
| 10 | Heat from direct flame, convection currents | 1 | 5.9% | |
| 11 | All other sources | 2 | 11.8% |
Per-capita rates let us compare apples to apples. Sierra Madre sits below the national average for incidents per resident.

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.
