Local Project Overview
Deck Construction · Washington County, Utah
Often exempt under 200 sq ft
In Washington County, a Deck Construction under 200 sq ft generally does not require a building permit. At or above 200 sq ft, a permit is required.
St. George's own zoning code confirms an accessory structure smaller than 200 square feet, that does not require a building permit, is allowed in the side and rear yard with no separation required, provided it is not permitted, constructed, or used prior to occupancy of the main structure. A compiled guide specific to the St. George area notes the region's lower snow loads, shallower frost depth, and less restrictive seismic design category (compared to the Wasatch Front) make deck construction generally less structurally demanding, though decks over 30 inches still require permits per general Utah practice. Building permits in Washington County are handled under the City of St. George Community Development (largest city); uni building code (IRC St. George City Code). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Washington County Building Department.

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).
Code Compliance & Inspections
Because of severe winter weather in Utah, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Utah State Building Code.
Zoning & Cost Factors
Utah zoning is heavily influenced by rapid population growth and water availability, with local governments increasingly adopting high-density transit-oriented zoning. Fortunately, Utah maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Frequently Asked Questions
What happens if I build a Deck Construction without a permit in Washington County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. 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 Utah?
Yes. Utah 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 Utah State Building Code.
How much does a Deck Construction permit cost in Washington County?
Permit fees vary by jurisdiction and by your project's valuation, so Washington County does not publish a single fixed figure. Confirm the exact fee with the local building department before applying.
