Developers

Do I need a building permit?

You will need to contact the Williamson Road and Bridge Division for a "Certificate of Compliance permit" which verifies if your property is in a flood plain. You will not need anything from the Road Dept, unless you are putting in a driveway (see Culvert/Driveway Policy). If you are in a city or city ETJ you should check with that city. Note that other agencies may require permitting including but not limited to cities (within their ETJ), Emergency Services Districts, TCEQ, the Williamson County and Cities Health District, etc. Please consult with the appropriate agencies.

What are the zoning regulations in Williamson County?

There are no zoning regulations in Williamson County. If you are inside the city limits you must follow the city's zoning regulations.

Does Williamson County issue a certificate of occupancy?

Let it be known that at this present time, Williamson County has no authority to zone property for land use nor does the county have the authority to issue certificate of occupancy.  It should also be noted that at this point in time, Williamson County has not adopted a resolution or order requiring the application of Subchapter F. “Residential Building Code Standards Applicable to Unincorporated Areas of Certain Counties” as found in Section 233 of the Local Government Code.  Therefore, Williamson County does not require any new residential construction to conform to any building code.

Roads

How do I get a culvert installed for my driveway?

You must contact us before you install a driveway. We will come out and look and tell you what size pipe that needs to be installed for your driveway. You then need to purchase the pipe and install it yourself, or we will install it for you if it is on a county maintained road at $5.00 per foot. For more information, please see the culvert regulations.

How can I find out if a road is maintained by the County?

If the road is a US or state road, is in the city limits of an incorporated city, or is a private road, the County does not maintain it. To find out, call Commissioners Court records at (512) 943-1515, contact the Road Dept. office at (512) 943-3330, or find the name of the road in the alphabetical listing of  Maintained Subdivisions and Roads.

How do I get specialty signs installed on a road?

For signs other than normal regulatory traffic signs, you will need to send a letter and or petition with signatures of area residents to our department stating your request and reasons/justification for needing the sign.
