The Pittsburgh market

Pittsburgh splits the paperwork. Plumbing permits, including the replacement card for a new water heater, come from the Allegheny County Health Department's Plumbing Division, not the City. Furnaces, AC and heat pumps fall under the City's Department of Permits, Licenses and Inspections (PLI), which requires a permit to install, alter, repair or replace any mechanical or fuel gas system; swapping a minor part that does not change the equipment's approval is exempt. PLI's 2026 schedule charges residential permits $6 per $1,000 of construction value (minimum $130) plus a $4.50 state fee. Who may pull mechanical permits was not confirmed, so ask PLI. Pennsylvania's housing leans old: EIA's 2020 survey found 19% of homes heat with a boiler and 13% with fuel oil, while 52% use natural gas.

A tankless conversion in Pittsburgh usually means a new vent and often a larger gas line, which may bring a second agency into the job. Ask the installer how the unit will be vented and who files each permit. Gas line sizing for a tankless heater is licensed-plumber work. Cold winter water lowers tankless output, so ask for the rated flow in January, and compare the quote against a standard tank of the same fuel.
