"New Townhouse Fire Safety Act"; requires automatic fire sprinkler systems in new townhomes.

This bill requires automatic fire sprinkler systems in all new townhouses built in New Jersey. It applies to newly constructed townhouses (defined as not previously occupied, with permits issued after the bill's effective date, for up to two households in attached units). The key mechanism mandates that construction permits cannot be approved without sprinkler system provisions, and directs the state to update building codes to require separate shut-off valves for sprinklers and domestic water. The requirements take effect seven months after the bill is enacted, affecting future developments but not existing buildings.
