Explanatory notes
Note 1. This data represents information gathered by the Residential Fire Safety Institute (RFSI) from fire departments and other sources. Based on the response to our inquiries, we estimate that the actual number of ordinances is substantially higher.
Note 2. Jurisdictions printed in italics may have ordinances covering 1-2 family homes, but this has not been verified. The RFSI staff is verifying the information and will continue to revise the list.
Note 3. An entry in column 2, "All," means that sprinklers are required in all structures including 1 & 2-family homes.
An entry in column 3, "R," means that sprinklers are required in all residential occupancies including 1 & 2-family homes.
An entry in column 4, "R3," means that sprinklers are required in all 1 & 2-famiy homes.
Note 4. An entry with a superscript indicates a restrictive note in column No. 8. For example, in Corte Madera, CA, the X in column No. 2 indicates that sprinklers are required in all occupancies, but the requirement only applies when the water flow is less than 500 GPM.
Note 5. The table does not include:
- Jurisdictions that offer incentives for sprinkler installation but do not require them by ordinance.
- Jurisdictions that require sprinklers on a case-by-case basis, such as a decision by a zoning board.
- Jurisdictions that only require sprinklers in model homes and leave sprinklers as a homebuyers option.
