DOB alteration permit and exemption check for insulation or air-sealing work

NYC DOB says most construction requires approval and permits, while 1 RCNY 101-14 identifies categories of minor alteration and ordinary repair work that may be exempt but still must comply with construction codes, the energy code, zoning, and other agency requirements. Insulation or air-sealing work should be checked with DOB when it opens assemblies, changes fire-rated or exterior conditions, affects mechanical/electrical/plumbing systems, or is part of a larger alteration.
