preventing municipalities from limiting dead-end road length if compliant with the state fire code.

SB 509 prevents municipalities from restricting the length of dead-end roads or cul-de-sacs in new subdivisions or building permits, provided the road design meets state fire code requirements. It directly affects developers seeking approval for new residential areas and local governments reviewing subdivision plans or building permits. The bill amends state laws to explicitly prohibit length-based denials when fire access compliance is certified, removing existing municipal restrictions. This creates a clear standard: if a dead-end road passes fire code checks, local governments cannot block development solely due to its length. The policy change applies immediately upon passage, with no additional cost or process for developers.
