Los Angeles County faces some of the nation's most severe wildfire risks. After the devastating 2025 Palisades and Eaton fires, LA County has accelerated fire code amendments and rebuild requirements — making supplemental water storage a critical need for thousands of properties.
A private fire suppression water storage tank is required when any of these conditions apply:
| Property Location / Type | Required Fire Flow | Typical Tank Size |
|---|---|---|
| Outside Fire Hazard Severity Zone (non-sprinklered) | 1,000 GPM at 20 PSI for 1 hour | 5,000–10,000 gal |
| In Fire Hazard Severity Zone (non-sprinklered) | 1,250 GPM at 20 PSI for 1 hour | 7,500–15,000 gal |
| Sprinklered dwelling (outside FHSZ) | 500 GPM at 20 PSI for 30 min | ~2,500 gal dedicated reserve |
| Rural/no hydrants (NFPA 1142 calculation) | Per NFPA 1142 formula | 5,000–10,000+ gal |
| Combined domestic + fire reserve | Fire reserve + 2,500 gal domestic | 5,000 gal common minimum |
Tank sizing in LA County is determined by the Authority Having Jurisdiction (LACFD Fire Marshal) based on NFPA 1142 calculations considering structure size, construction type, sprinkler status, and exposure hazards. The figures above are typical residential ranges — your specific requirement will be confirmed during consultation.
Properties in any Fire Hazard Severity Zone (High or Very High) face stricter standards. In LA County, the LACFD designates WUI Fire Areas and enforces VHFHSZ requirements under Title 32, Chapter 49 of the 2023 LA County Fire Code (effective January 11, 2024).
The January 2025 Palisades and Eaton fires have accelerated major regulatory changes in LA County:
Commercial and industrial properties in LA County face fire flow demands of 6,000–9,000 GPM — with dense business districts requiring up to 12,000 GPM. Large warehouses, hospital campuses, and industrial facilities often need 50,000 to 500,000+ gallon fire water storage systems.
