DOB plumbing, mechanical, or emergency-work permit check for water heater work
NYC DOB says plumbing work that alters, rearranges, relocates, or permanently removes piping must be supervised by a Licensed Master Plumber or qualified contractor and permitted by DOB. For water heater repair, replacement, or conversion, confirm the DOB filing route because the work can involve plumbing, gas, venting, electrical, heating or hot-water equipment, and emergency-work rules during the heating season.
