Do I need a permit for garage conversion in Merchantville?

Permit required

Yes. In New Jersey, garage conversion generally requires a permit, and Merchantville is no exception.

Converting a garage to living space alters the structure and its systems, which requires a construction permit (N.J.A.C. 5:23-2.14(a)). When finished space is created in previously unfinished space, receptacle and lighting outlets must meet the electrical subcode, and a new bedroom needs a hard-wired smoke alarm inside it, another nearby, and a qualifying escape window or door (N.J.A.C. 5:23-6.6(e)). Where work exposes framing of walls, floors, ceilings, or roofs that enclose conditioned space, accessible insulation voids must be filled to residential energy code R-values (N.J.A.C. 5:23-6.6(e)). Alterations trigger smoke alarms on each level and carbon monoxide alarms where there is a fuel-burning appliance or attached garage (N.J.A.C. 5:23-6.6(f) and (g)).
