Do you need a permit to build a deck in Virginia?

The short version

Virginia has one building code for the whole state, the Uniform Statewide Building Code, which every city and county building department enforces. Under it, a permit has to be obtained before work starts on the construction of a building or structure, and on installations or alterations involving any structural component.^[1] A deck is a structure with footings, posts, beams and joists, so a new one needs a permit.

The code does list work that is exempt from permits. The list covers one-story detached sheds and playhouses of 256 square feet or less, fences, temporary ramps for houses where the entrance is no more than 30 inches above grade, flagpoles and small shallow pools. Decks are not on it.^[1] If you read elsewhere that a low or freestanding deck needs no permit, check it with your own building department, because the Virginia list is the one that applies.

Counties say the same thing plainly. Henrico County says a building permit is required for construction of all residential wood and composite decks.^[2] Loudoun County says a building permit and a zoning permit are required for all decks.^[3] York County lists a building permit for deck projects, and says an electrical permit may be required depending on the scope of work.^[4]

What the application asks for

Details vary by county, but the pieces are similar:

• Where it goes. Each of the three counties asks for a plot plan or plat showing the property lines and the deck's distance from them, so the county can check setbacks.^[2][3][4]
• How it is built. Henrico asks for a plan view with the deck's dimensions and the existing house, windows and doors near it, and whether the deck is attached to the house or freestanding.^[2] Loudoun accepts its own Typical Deck Detail in place of drawn deck plans.^[3] Henrico notes that decks have to be designed for a 40 pound per square foot live load and a 10 pound per square foot dead load.^[2]
• Anything electric. Loudoun says an electrical permit may also be required for stairway lighting, hot tubs or spas.^[3]
• Who is applying. A homeowner applying for their own permit in Henrico has to attach a signed Owner's Statement of Responsibility.^[2]

Fees are set locally. As an example, when we checked on October 20, 2026: In Loudoun, a county typical deck under 1,000 square feet outside an incorporated town cost $265 for the building and zoning permits together.^[3] Your county's fee schedule will differ.

The inspections

A deck permit comes with inspections at set stages. Loudoun requires three inspections: the footing holes before concrete is placed, the joists, beams and connections before the decking goes down, and a final inspection.^[3] Henrico requires a footing inspection after excavation and a final inspection when the deck is complete with all handrails and guardrails installed, before use.^[2] Keep the paperwork handy: Loudoun says the approved plans or typical deck detail must be on the job site, or no inspection will be performed.^[3]

Footings mean digging, and Virginia law says no one may begin any excavation without first submitting a locate request to the notification center.^[5] Henrico points homeowners to Miss Utility at 811 or 1-800-552-7001.^[2]

Repairs to an existing deck

Replacing a few boards is different from building a deck. The statewide exemptions include construction work deemed by the building official to be minor and ordinary and that does not adversely affect public health or general safety.^[1] Work on the structure itself, such as joists, beams, posts or the ledger that ties the deck to the house, falls under the permit rule for structural components. Call your building department before you start.

Hiring a deck builder

When a contractor builds the deck, whoever applies for a permit to build or improve a structure has to show the building department proof of a contractor licence, or file a written statement that they are not subject to licensing.^[1] Virginia's Board for Contractors says work valued at $1,000 or more needs a valid Virginia contractor's licence in the right category.^[6]

The board also says the contractor should apply for and obtain any necessary building permits, and the contract should say so.^[6] Be careful with a builder who asks you to pull the permit in your name: the permit holder becomes the general contractor and takes on responsibility for the overall job.^[6] And do not let work start until the contractor gives you copies of the issued permits.^[6] Before you sign, check the builder's licence on DPOR's record.
