Concerns implementation of fire sprinkler system requirements in newly constructed townhouses.

This bill extends the deadline for implementing fire sprinkler systems in new townhouses from 7 to 25 months after the original law's enactment. It requires construction permit applications for new townhouses (defined as attached single-family homes with yard/public access on two sides) to include sprinkler system plans before being approved, unless the project had certain pre-existing approvals. Key exemptions include developments with prior municipal zoning approvals, affordable housing agreements, or building permits submitted before the new deadline. The bill also delays the timeline for the state to adopt sprinkler design rules from 5 to 13 months after this bill's enactment.
