Local Project Overview

Deck Construction · Montgomery County, Maryland

Permit required

In Maryland, a Deck Construction requires a building permit.

DPS's own page states textually: "A building permit is required for all decks that are supported by footings regardless of the height above grade" no size or height exemption. The county offers pre-approved Residential Deck Details templates for single-span, single-level decks (without roofs, hot tubs, or added loads) that can substitute for custom plans. Distinctively, the Maryland High Voltage Line Act prohibits any person or object from coming within 10 feet of high-voltage power lines, a real safety constraint the county's deck standard details specifically call out. Plans are reviewed under the Montgomery County Department of Permitting Services (DPS) code (IRC Maryland Building Pe); apply through Montgomery County Department of Permitting Services before work begins.

Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).

Frequently Asked Questions

What are the specific penalties for unpermitted Deck Construction work in urban Montgomery County?

You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.

Can a homeowner pull their own Deck Construction permit in Maryland?

Yes. Maryland generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Maryland Building Performance Standards.
