Establishes exemptions and revises implementation timeline for requirement that newly constructed townhouses be installed with automatic fire sprinkler system.

This bill modifies a 2023 law requiring automatic fire sprinkler systems in new townhouses by extending the compliance deadline from the seventh to the thirteenth month after the law's enactment. It also creates an exemption for townhouses where a construction permit application was submitted to a government agency before this bill passed, removing the sprinkler requirement for those projects. Additionally, the bill extends the deadline for the state to adopt new rules about sprinkler systems from five to twelve months after the law's enactment. These changes primarily affect new townhouse developers and builders in New Jersey who must comply with the updated timeline and exemption.
