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

This bill modifies New Jersey's requirement for automatic fire sprinkler systems in new townhouses. It extends the deadline for installation from 7 months to 13 months after the original law's enactment (P.L.2023, c.265) and exempts townhouse projects that submitted construction permit applications before this bill passed. The bill also delays the deadline for the Commissioner of Community Affairs to adopt related building code rules from 5 months to 12 months after enactment. These changes primarily affect developers and builders constructing new townhouses under specific building codes.
