DOB mechanical, electrical, and plumbing permit check for heat pump work
NYC DOB says most construction requires DOB approval and permits, while certain mechanical work may be exempt under 1 RCNY 101-14. For heat pump installation or replacement, confirm the DOB path before work because the scope can include mechanical equipment, electrical wiring, plumbing or gas changes, roof or wall penetrations, structural support, energy-code documentation, or emergency heating and hot-water work.
