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

This bill requires new townhouses in New Jersey to include automatic fire sprinkler systems in their construction permits, effective 25 months after the law's enactment. It exempts townhouse projects that submitted permit applications or development plans to local agencies before February 2024 (the date of P.L.2024, c.42). The law amends existing construction codes to align with the 2021 International Residential Code for sprinkler system design and installation. The Commissioner of Community Affairs must adopt implementing rules within 13 months of enactment. This directly affects developers and builders constructing new townhouse projects after the specified deadline.
