Permits single exit stairwells in certain new residential buildings under State Uniform Construction Code.

This bill allows municipalities in New Jersey to permit single exit stairwells in new multi-unit residential buildings (up to six stories) that house permanent residents, rather than requiring multiple exits. It specifically applies to "Group R-2" buildings (defined as residential structures with more than two dwelling units) and allows the ground floor to be used for non-hazardous non-residential purposes (like retail) if served by separate entrances. Municipalities must adopt ordinances following a model provided by the Department of Community Affairs, and the rule only affects new construction applications submitted after the law takes effect. The change modifies existing building code requirements for residential safety standards.
