Pittsburgh Deck Permits & Code Compliance

Alliance Deck Builders of Pittsburgh takes the headache out of building permits and code approvals. We work directly with Pittsburgh’s Department of Permits, Licenses, and Inspections to ensure your deck project meets all structural, zoning, and safety standards. Whether you’re in the city or a surrounding township like Bethel Park or Ross, we handle every document, inspection, and engineering requirement. We know what’s allowed, where setbacks apply, and how to get your deck approved without delays.

Built to Withstand Pittsburgh’s Four Seasons

Durable Decks Engineered for Local Conditions

From freezing winters to humid summers, Pittsburgh weather puts decks to the test. That’s why we build using pressure-treated framing, composite surfaces, and galvanized fasteners designed for long-term exposure. We slope every frame for proper runoff and ensure drainage doesn’t undermine your footings. In high-snowfall zones like Mount Lebanon or Upper St. Clair, we calculate snow loads into our structural plans. When Pittsburgh weather hits hard, your deck will be ready for it—built tough and sealed right.
