Do I Need a Permit for a Bathroom Remodel in Pittsburgh, PA?

Bathroom remodeling in Pittsburgh is governed by the same split-agency framework that applies to kitchen remodels: PLI (Permits, Licenses, and Inspections) handles building and electrical permits; the Allegheny County Health Department Plumbing Division handles plumbing permits for all drain, vent, supply, and gas piping work. Cosmetic work — new tile, fixtures replacing at the same locations without moving pipes, paint, new vanity replacing old vanity at the same drain and supply connections — requires no permits. Any plumbing modification (toilet relocation, shower drain moved, bathtub to walk-in shower conversion requiring new drain rough-in) requires an Allegheny County Health Department plumbing permit at (412) 578-8036. Any new electrical circuit or wiring (GFCI outlet additions at new locations, exhaust fan on new circuit) requires a PLI electrical permit. Pennsylvania requires PA DLI-licensed electricians for permitted electrical work. No SB 407 trigger. No mandatory utility inspection from Peoples Gas or Duquesne Light. Cold-climate consideration: supply pipes routed through exterior walls in Pittsburgh's older rowhouses are at risk in extreme cold — route through interior walls where possible.

Pittsburgh bathroom permit rules — Allegheny County Health vs. PLI

The defining fact of Pittsburgh bathroom permitting: the Allegheny County Health Department Plumbing Division issues ALL plumbing permits — not PLI. This split applies to any bathroom plumbing modification, however minor. A bathroom renovation that moves a vanity 12 inches, requiring new drain rough-in at the new location, needs an Allegheny County Health Dept plumbing permit from (412) 578-8036. The Health Dept's Citizen Access Portal at alleghenycounty.us/Services/Health-Department/Plumbing-Program handles permit applications and renewals. Work must be performed by a licensed Master Plumber who pulls the permit.

PLI handles building and electrical permits for bathroom remodels. Structural changes — moving walls, new openings — require a PLI BDA via OneStopPGH. Electrical changes — new GFCI outlets at new locations, exhaust fan on new wiring — require a PLI electrical permit applied through OneStopPGH. Pennsylvania requires PA DLI-licensed electricians for permitted electrical work, unlike Ohio's no-state-license environment.

Peoples Natural Gas (1-800-764-0111) and Duquesne Light (412-393-7100) don't require mandatory utility inspections for bathroom work. If a bathroom is adding a gas supply (radiant heated floor with gas boiler, or a gas fireplace), the gas piping modification is under the Allegheny County Health Dept plumbing permit — not a separate utility inspection. No PSE&G-style yellow sticker or utility sign-off required in Pittsburgh.

No mandatory utility inspectionPeoples Gas (1-800-764-0111) and Duquesne Light (412-393-7100) don't require mandatory inspections for bathroom work. Gas piping in the bathroom is under the Allegheny County Health Dept plumbing permit. No PSE&G-style yellow sticker required.
PA HIC + Pittsburgh city licenseBoth required for contractors performing permitted bathroom work. Verify PA HIC at Attorney General website; verify city license by calling PLI at (412) 255-2175. Neither alone is sufficient for permitted work in Pittsburgh.
Cold-climate plumbing — exterior wallsPittsburgh's cold winters (sub-10°F possible) create freeze risk for supply pipes in exterior walls or unheated spaces. Route supply pipes through interior wall cavities where possible. Address this proactively during bathroom renovation — not after a burst pipe in February.
Pittsburgh bathroom permits require coordinating with two agencies — Allegheny County Health Dept for plumbing, PLI for electrical and structural. Both must be satisfied for final approval.

The Allegheny County Health Department Plumbing Division — not PLI. Call (412) 578-8036 or apply through the Citizen Access Portal at alleghenycounty.us. Work must be performed by a licensed Master Plumber. The Health Dept conducts its own inspections entirely independently from PLI's electrical inspections.

Do I need a permit if I'm just replacing my toilet in Pittsburgh?

Not if the toilet is being replaced at the same rough-in location without moving any pipes — that's maintenance. A plumbing permit from the Allegheny County Health Dept is required if the toilet is being relocated, if new rough-in is needed, or if supply connections are being modified. Call (412) 578-8036 to confirm for your specific scope.

Does Peoples Gas need to approve bathroom work in Pittsburgh?

No — Peoples Gas (1-800-764-0111) doesn't require a mandatory inspection for interior gas work. Gas piping modifications in a bathroom are covered by the Allegheny County Health Dept plumbing permit. No PSE&G-style utility inspection required in Pittsburgh.

Can a homeowner pull their own plumbing permit in Pittsburgh?

The Allegheny County Health Dept plumbing permit must be pulled by a licensed Master Plumber — not by the homeowner. This is unlike some jurisdictions that allow owner-occupant plumbing self-installation. Call (412) 578-8036 for current requirements and to confirm the licensed plumber who will pull the permit for your project.

How long does a Pittsburgh bathroom remodel permit take?

Allegheny County Health Dept plumbing: call (412) 578-8036 for current processing timeline. PLI electrical via OneStopPGH: 1-2 weeks for standard residential. Apply both simultaneously to avoid sequential delays. Inspections: Health Dept and PLI inspectors scheduled independently. Total to final approvals from both agencies: 2-5 weeks for standard bathroom renovation.

What's the split between Allegheny County Health and PLI for bathroom work?

Allegheny County Health Dept: all drain, vent, supply, and gas piping work — includes moving pipes, new rough-ins, new fixture connections, gas line modifications. PLI: all electrical work (new circuits, GFCI at new locations), structural changes (wall modifications), and mechanical (exhaust fan ductwork). If your bathroom remodel involves plumbing AND electrical changes, both agencies must approve their respective scopes before the renovation is complete.
