Pittsburgh Deck, Electrical, and Mechanical Permit Guide

Pittsburgh decks, electrical systems, and mechanical or fuel-gas systems use separate residential permit paths, with zoning approval still needed for some low decks.

Permit takeaway

Pittsburgh says uncovered decks no more than 30 inches above grade do not require a building permit but do require zoning approval; all other decks require building and occupancy permits.

Zoning and placement

Low uncovered decks, fences six feet or less, carports, parking pads, and similar work may be zoning-review-only rather than PLI building review.

Building and trade review

Pittsburgh requires residential electrical permits for renovating, repairing, extending, modifying, or installing electrical systems, and mechanical permits for mechanical or fuel-gas systems.

Call before applying when

Call before applying if the deck is over 30 inches, covered, not a simple single-story wood deck, includes electrical or mechanical work, or needs sealed drawings.
