Frequently Asked Questions

Do I need a building permit for a deck in Pennsylvania?

Yes, under the PA UCC, a permit is typically required if the deck is more than 30 inches above the ground, has a roof, or is attached to the house. Always check with your local municipality as some have stricter amendments.

What is the average cost of a deck vs. a patio in PA?

A pressure-treated wood deck typically costs $25–$50 per square foot, while a paver patio costs $10–$25 per square foot. Patios are generally cheaper upfront, but decks often offer a higher return on investment (up to 75%) in the PA real estate market.

What are the railing requirements for elevated decks in PA?

For any deck surface higher than 30 inches above grade, Pennsylvania code requires a guardrail at least 36 inches high. The vertical balusters must be spaced so that a 4-inch sphere cannot pass through.

Is Bluestone a good choice for a Pennsylvania patio?

Yes, Pennsylvania Bluestone is a local natural stone that is highly durable and aesthetically fitting for the region. However, it should be installed on a well-drained gravel base to prevent shifting during freeze-thaw cycles.
