Central Texas Metal Buildings

Round Rock, Williamson County, TX

Metal buildings in Round Rock, Texas

A metal building in Round Rock is usually a detached garage, a storage shed or a workshop behind a house, or a steel building on a business park or light industrial lot, and a request from this page goes to one independent metal building contractor, who decides which projects to take.

Inside this Williamson County city every structure takes a permit, down to a shed under 200 square feet, and the permit names every contractor on the job before it issues. Zoning then sets the height, the yard and, on business land, how much of a wall may be metal.

Show the full introduction

For an address outside the city limits, in the ETJ or elsewhere in Williamson County, the city's building office asks you to call (512) 218-5550 and confirm where it sits, and past the city the county lists no building permit.

Inside Round Rock

Building permit for any structure, four to eight week review

Round Rock requires a building permit for work on any building or structure in the city, including a shed under 200 square feet because it counts as an accessory structure, and has adopted the 2024 International codes and the 2023 National Electrical Code plus the Texas Accessibility Standards.

Williamson County, outside city limits

No county building permit, building code or certificate of occupancy

Williamson County's own pages answer the building permit question by pointing to the County Engineer's Road and Bridge Division, which issues a Certificate of Compliance that verifies whether the property is in a floodplain, and say nothing else is needed from that office unless a driveway is being built.

The source was read and does not list this. From Williamson County, frequently asked questions, infrastructure and developers (read September 20, 2026).

Start with the address: the city answers inside its limits, and the county past them. The whole record is on that county's sheet.

Inside Round Rock, in the ETJ, or out in the county: who permits a metal building?

Inside the city, the Building Inspection Division does, from 301 W. Bagdad Ave., and its rule has no size floor: any building or structure in the city takes a permit, and so does work in the Chandler Creek and Vista Oaks municipal utility districts. Round Rock runs a one-permit system, so the electrical, plumbing and mechanical contractors go on the same application before it can issue. Every contractor and subcontractor registers with the city, at no fee, and a permit is void if the work has not started within six months.

Outside the limits, the division asks owners to call (512) 218-5550 first and confirm whether the address falls in the ETJ or elsewhere in Williamson County. The statute behind that line is Local Government Code 212.049: the plat subchapter hands a city no power to demand building permits in its ETJ. Past the city, Williamson County's own pages say it issues no building permits, and its Certificate of Compliance checks the floodplain, not the building. The county's remaining desks are on the Williamson County sheet; Georgetown ties its ETJ permits to the utility provider instead, on metal buildings in Georgetown.

What limits a metal garage, shed or shop behind a Round Rock house?

Yard, height and easements. The division's page allows carports, sheds and similar structures only in side or rear yards, never in a front yard or over a driveway, and keeps them out of building setbacks and every easement: utility, drainage, water, sewer and stormwater. Any accessory structure tops out at 15 feet, measured from existing ground to the highest point of the roof, and it takes an Accessory Structure application, with its wiring or plumbing on the same permit, before it is built or set.

The zoning chart in Section 2-26 of the city code agrees on 15 feet in every residential district but one: AG, where it lists 35 feet for an accessory building. On AG and SF-R land the chart sets a 20-foot accessory setback and caps building coverage at 10 percent of the lot, house and outbuildings counted together, and on every residential lot accessory buildings stay out of the front street yard. A shop behind a house also stays residential: Section 2-93 keeps accessory uses in a residential district from commercial purposes other than a legitimate home occupation. Door, span and slab choices for a garage: detached garages and RV garages.

How much of a Round Rock commercial building can be metal?

That depends on the zoning district, and the code answers it district by district. In LI, light industrial, architectural steel or metal may make up 33 percent of the total exterior wall finish at most; other steel or metal, such as unfinished corrugated aluminum, may not face a public street, an access drive or a residential lot; and Quonset style buildings are prohibited. BP, the business park district, lists architecturally finished steel or metal among its permitted finishes. The OF-1 office district and the PF-1 and PF-2 public facilities districts want at least half the wall in natural stone, simulated stone or brick, and PF-3 wants 75 percent. The I industrial district sets no wall finish rule, but new industrial development may not locate within 500 feet of single-family or two-family uses or of designated arterial roads, and accessory buildings in the office, business park and industrial districts stop at 15 feet.

The permit path, from the city's new commercial construction page: review usually runs about four to eight weeks after the application is accepted; a building over 5,000 square feet needs an engineer-stamped plan set; the application carries a 2024 ComCheck, and a project over $50,000 its TDLR number. The certificate of occupancy issues within three to five business days of the final inspection, and standalone commercial permit fees scale with valuation, from $50 up to $2,000 of value to $1,875 for the first $500,000 plus $2 per additional thousand. The city adopted the 2024 International Building Code, with all its appendices, by ordinance on December 18, 2025. The commercial lane in full: commercial metal buildings.

What do Round Rock's flood and tree rules do to a building pad?

Both come before the slab is formed. Inside the city, a floodplain development permit is required in any special flood hazard area, under an ordinance that adopts both the Williamson County flood study of December 20, 2019 and the Travis County study of August 18, 2014, administered by the director of public works. A new or substantially improved commercial or other non-residential building needs its lowest floor at or above base flood level, or a watertight design below it that an engineer or architect certifies.

Trees are the other line item on a business lot. A tree eight inches or more across, measured 4.5 feet up, is protected, except that on developed lots in SF-1, SF-2, SF-3, SF-D, MH, TF and MU-L, and on developed lots under 15,000 square feet elsewhere, only monarch trees are, and on undeveloped lots in those cases the line is 20 inches. Hackberry, chinaberry, Chinese tallow, Osage orange, Texas common cedar and honey mesquite are not protected. Removal takes a permit, and replacement is inch for inch or $150 an inch from eight to 19.99 inches, two to one or $300 an inch up to monarch size, and three to one or $450 an inch beyond. Grading and site development work in or within 500 feet of a residential zone runs only from 7:00 a.m. to 6:00 p.m. Pad work and stormwater acreage: pad, grading and stormwater acreage.

Creek limestone, chalk or clay: what sits under a Round Rock slab?

The town is named for its rock. The 1983 Soil Survey of Williamson County says Round Rock took its name from a limestone pedestal carved by Brushy Creek, and that the hard limestone in the creek bed there is the type that underlies the Eckrant soils along the creek. Right beside the water are Oakalla soils, and the survey says its occasionally flooded Oakalla unit floods about every two to eight years and is unsuited to urban uses for that reason.

East along U.S. 79 the survey found chalk: its typical Eddy soil, a very shallow soil formed in soft marine chalk, was described 4.5 miles east of Interstate 35. It calls that chalk a good foundation for houses and streets, while warning that hard chalk at shallow depth limits foundations, septic systems and utility lines. Countywide, the same survey puts the Del Rio Clay in a narrow belt mainly along Interstate 35 under the Houston Black clays, whose dry-season cracks run from 0.4 inch to four inches wide. The foundation engineering: slab and anchor design.

Who handles septic, power and the state filings for a Round Rock building?

Septic stays with Williamson County even inside the city: the County Engineer's program covers the county outside Austin and treats every building but a single-family house as commercial. For power, the city's building page lists Oncor as the electricity contact, and Oncor's new construction process runs through an online request and a project manager who calls or emails within two business days; Pedernales Electric Cooperative's tariff also names Round Rock among its franchise cities, so confirm which lines reach the address first.

Three state items apply whatever the city decides. At $50,000 or more in total estimated cost, TDLR registration and accessibility plan review apply. One acre or more of disturbed ground, counting any larger common plan, brings TCEQ construction stormwater coverage. And Williamson County is on TCEQ's Edwards Aquifer program list, where a Contributing Zone Plan comes into play at five disturbed acres or as part of a larger plan, and the official maps decide each parcel.

Questions on a metal building in Round Rock

Does a small shed in Round Rock need a building permit?

Yes. The city's building inspection FAQ says a shed under 200 square feet and 15 feet or less in height still needs a permit, because it counts as an accessory structure. It goes in on an Accessory Structure building application and may sit only in a side or rear yard, clear of setbacks and easements.

How tall can a metal garage or shop be in Round Rock?

The building inspection page caps any accessory structure at 15 feet, measured from existing ground to the highest point of the roof. The zoning chart lists the same 15 feet in every residential district except AG, where it lists 35 feet for an accessory building.

Can a light industrial building in Round Rock have metal walls?

Partly. In the LI district, architectural steel or metal may make up to 33 percent of the total exterior wall finish, other steel or metal such as unfinished corrugated aluminum may not face a public street, an access drive or a residential lot, and Quonset style buildings are prohibited.

What is Round Rock's one-permit system?

Every contractor on the job, including the electrical, plumbing and mechanical trades, goes on one building permit application before the permit can issue. Contractors and subcontractors register with the city at no fee, and the permit becomes invalid if the work is not commenced within six months.
