Do you need a permit for a deck in Round Rock, TX?
Yes, in almost every case. The City of Round Rock lists wood decks and covered patios as residential projects that need a building permit, and it has a separate permit for accessory structures such as pergolas, gazebos, and outdoor kitchens. These permits are issued by the city, not by Williamson County.
You may have heard that a small, low, freestanding deck is exempt. The model International Residential Code does include an exemption for decks under 200 square feet that are no more than 30 inches above grade, not attached to the house, and not serving a required exit door. Round Rock's permit page does not describe that exemption, so do not assume it applies. Ask the Building Inspection division directly whether your specific deck needs a permit, and get the answer in writing if the answer is no.
Which building code does Round Rock use?
Round Rock lists the 2024 International Residential Code, the 2024 International Building Code, the 2024 International Energy Conservation Code, and the 2023 National Electrical Code as its currently adopted codes. That puts Round Rock on a newer code edition than several neighboring cities that still use the 2021 codes.
For a deck, the IRC edition matters for ledger attachment, footing sizes, guard and stair details, and lateral load connections. If you are reusing a plan from a friend's deck in another city, have it checked against the 2024 IRC before submitting.
How much does a Round Rock deck permit cost?
Round Rock publishes flat fees for these projects. A wood deck or uncovered patio without electrical or plumbing is $125. A wood deck or covered patio without electrical or plumbing is $200. A wood deck or covered patio with electrical and/or plumbing is $300.
For accessory structures, a pergola or gazebo without utilities is $125, and one with electrical or plumbing is $300. Two inspections of the same type are included in the permit fee. If the same type of inspection fails twice, the city charges a $75 re-inspection fee for each additional inspection. Fees can change, so check the city's page when you apply.
How long does a Round Rock deck permit take?
The city says the review process will take approximately 30 business days from the date your application is received and accepted. That is about six weeks on the calendar, and it is noticeably longer than the 5 to 10 business days people often quote for Williamson County cities.
Build that into your schedule. If you want a covered patio finished for a spring party or a fall football season, the permit application should go in well before the build window. Incomplete submittals restart the clock, so a clean first submittal is the single best way to save time.
What setbacks apply to decks and pergolas in Round Rock?
On the deck and covered patio permit, Round Rock says encroachment into easements or the 5 foot side and rear setbacks is prohibited, and it asks you to note the separation in feet between the structure and each property line on your submittal. For accessory structures like pergolas and gazebos, the city also prohibits encroachment into setbacks or easements.
The city's accessory structure permit page lists a maximum height of 15 feet 0 inches, measured from the existing ground level to the highest point of the roof. Your zoning district, plat, or HOA may be stricter. Utility and drainage easements along back fences are common in Round Rock subdivisions, so pull your survey early and look for them before you settle on a footprint.
What do you submit for a Round Rock deck or patio cover permit?
Applications go through the Round Rock Permit Portal. For a deck or covered patio, the city asks for complete construction plans with dimensions and materials, a property survey marked with the proposed structure location, the separation in feet to the property lines, and electrical or plumbing details if the project includes them.
Pergolas, gazebos, and other accessory structures need the same basic package: legible construction plans with dimensions and materials, a survey showing the location, separation from property lines, and utility details when applicable.
How do inspections work in Round Rock?
Inspections are requested after the permit is issued. The city says requests made by 4 p.m. are scheduled for the next business day, and inspections run Monday through Friday. Two inspections of the same type are included in your fee.
The permit page does not spell out the inspection sequence for a deck. Ask the city which inspections your permit will require, since footings are typically inspected before concrete is poured and a final inspection closes out the permit. Covered patios with fans or lighting will also need electrical inspections.
Do you also need HOA approval in Round Rock?
If your home is in an HOA community, almost certainly yes. Many Round Rock subdivisions, especially the master-planned ones, have an architectural review process. A city permit confirms code compliance. HOA approval confirms the design meets the community's rules on materials, colors, placement, and height. One does not replace the other, and an HOA can require changes to work built without its approval.
Ask your HOA for its current architectural guidelines and application form before you finalize a design, and ask how long its review takes so you can run it alongside the city review.
