Bill Summary · S 4642

Legislative bill overview

S 4642 modifies New Jersey's Uniform Construction Code to allow single exit stairwells in certain new residential buildings, rather than requiring the current standard of multiple egress routes. The bill carves out exceptions to existing fire safety codes that typically mandate dual or multiple means of egress from residential structures.

Why is this important

Building egress requirements exist primarily to protect occupant safety during emergencies like fires, where multiple exits allow people to evacuate even if one route is blocked. Relaxing these standards could increase risk for residents, though it may reduce construction costs and make housing development more economically feasible in certain circumstances.

Potential points of contention

  • Fire safety vs. affordability tradeoff: Reducing exit requirements lowers construction costs but directly contradicts decades of fire safety research showing multiple egress routes save lives in emergencies
  • Scope ambiguity: The bill's language "certain new residential buildings" lacks clear definition—which building types, sizes, and occupancy levels would qualify for this exemption?
  • Insurance and liability implications: Single-exit buildings may face higher insurance premiums or exclusions, and developers/owners could face liability claims if occupants are harmed due to limited egress during emergencies
