Do I need a permit for addition or structural alteration in Jamesburg?
Yes. In New Jersey, addition or structural alteration generally requires a permit, and Jamesburg is no exception.
A construction permit is required to construct, enlarge, or alter a structure (N.J.A.C. 5:23-2.14(a)); an addition must meet new-construction rules while related work in the existing house follows the rehabilitation subcode (N.J.A.C. 5:23-2.5). Energy subcode calculations must be submitted for all additions (N.J.A.C. 5:23-2.15(f)1vi). Plans must be sealed by a registered architect or licensed engineer, except that the construction official waives sealed plans for a single-family owner who prepares his or her own plans for a detached private residence and files an affidavit (N.J.A.C. 5:23-2.15(f)1ix). Alteration work in a one- or two-family home triggers smoke alarms on each level and outside sleeping areas, 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)).
