Do I need a permit for water heater replacement in City of Pittsburgh?
Most likely yes. Water heater replacement usually requires a permit in Pennsylvania. Confirm the specifics with City of Pittsburgh.
Under the Pennsylvania UCC replacing a water heater is plumbing-system work (and gas work for a gas unit) that requires a permit in most municipalities, even for a like-for-like swap. Emergency replacement of a failed water heater may proceed if a permit application is filed with the code official within 3 business days. Switching fuel type or converting to tankless adds gas, electrical, and venting scope. In the City of Pittsburgh, plumbing not associated with sprinkler systems is regulated by the Allegheny County Health Department Plumbing Division, not by PLI, so a water heater's water-side permit generally comes from the county rather than the city. PLI does not treat altering, replacing, or relocating water supply or waste piping as an ordinary repair, and a gas-fired unit also involves the fuel gas code under a PLI Mechanical Systems permit. PermitRoadmap is an independent informational service, not the City of Pittsburgh or Allegheny County; confirm the plumbing permit with the Allegheny County Health Department and the gas permit with PLI.
