Do I need a permit for a driveway entrance onto a county road or highway in Texas?
Reviewed October 2026 by Shannon Miles Group
Yes, in nearly every case. Any new access connection into a road right of way needs permission: TxDOT issues an access driveway permit through the local district office for state highways, FM roads, loops, and spurs, and county road departments issue their own entrance or culvert permits for county roads. The permit process, sizing, and fees vary by county, so check with the road authority that owns your frontage before you dig.
The road right of way is not your land.
New landowners are often surprised that the strip of road where their driveway meets the pavement belongs to the public. Driveways, culverts, gates, and cattle guards placed there sit in the right of way, where they affect drainage, sight distance, and safety for everyone using the road. That is why both TxDOT and Texas counties require approval before construction starts.
This matters before you buy, not just before you build. A tract whose only frontage is a busy FM road may need a TxDOT access permit with specific design standards for the entrance, and a tract whose access crosses a county road with a restrictive culvert policy may come with real construction and maintenance obligations. Verify the access situation and the permitting path as part of your due diligence, and your title commitment will tell you whether the driveway and any easement are recorded.
TxDOT roads versus county roads.
| Road type | Who approves the entrance | What to expect |
|---|---|---|
| State highway, FM road, loop, or spur | TxDOT, through the local district office and its access management standards | An application with location and design details, review against sight-distance and driveway width standards, and approval before any work in the right of way. |
| County road | County road and bridge department, precinct commissioner, or county engineer | A county-specific culvert or entrance permit, usually with required culvert sizing, installation rules, and who maintains the culvert at the county line. |
| City street or ETJ | City engineering or public works department | Urban driveway standards, curb cuts, and sidewalk and drainage requirements before any new approach. |
What buyers should ask county by county.
In Lamar County, the county publishes a culvert policy and a culvert permit for driveway entrances on county roads, available through the county website or the road and bridge office. Fannin, Red River, Delta, Hopkins, Hunt, and Grayson Counties each run their own road departments with their own forms and culvert specifications, and the requirements change depending on the precinct where the property sits.
For state routes, every FM and highway frontage in the region is handled through the TxDOT district office that covers the county, and the access standards in the TxDOT Access Management Manual apply. A residential driveway is held to lighter standards than a commercial entrance, but both need the permit before construction.
The practical checklist: confirm the road that fronts your tract, ask the road authority what permit applies, get the culvert size and installation rules in writing, and budget for the work. A septic system, building site, and driveway are often permitted separately, so treat the entrance as its own line item in the land budget.
Geographic scope
This answer covers Texas and applies across Northeast Texas, including Lamar, Red River, Delta, Hopkins, Hunt, Fannin, and Grayson Counties. County policies differ, so verify the specific culvert or entrance permit with the road department in the county where the property sits, and with the appropriate TxDOT district for state roads.
In Southeast Oklahoma, county road departments and the Oklahoma Department of Transportation run their own access approval processes. If you are buying acreage in Bryan or McCurtain County, confirm the county entrance and culvert requirements with the county road department there.

The entrance questions we hear most.
Who issues the permit: TxDOT or the county?
It depends on who owns and maintains the road. For a state highway, FM road, loop, or spur, TxDOT issues the access permit through the local district office. For a county road, the county road department or precinct commissioner handles it, often through a culvert or entrance permit. Ask your agent and the road authority which one applies to the frontage on your tract.
Do I need a permit just for a gate or cattle guard?
Yes, any new access connection into the right of way, including a gate or cattle guard, typically requires approval because the structure sits in the road right of way and affects drainage and sight distance. County culvert policies in Northeast Texas generally cover driveway entrances, culverts, and the grading around them in the right of way.
Can I install the culvert myself?
Many counties require the property owner to provide the correct culvert size and may require a licensed contractor, an inspection, or both. County policies typically specify culvert sizing, materials, and who is responsible for installation and maintenance. Read the county's culvert policy document before you buy materials or schedule work.
What happens if I build an entrance without a permit?
Unpermitted work in the right of way can be ordered removed at your cost, and it can create safety and drainage problems on roads you do not own. A noncompliant entrance can also be an issue for financing and for the county when you later apply for a permit or a building certificate. Getting approval before you dig is the cheapest path.

The access question in context.
A driveway permit is one part of the access picture. Our road access and frontage guide distinguishes legal access from physical access, and the private road guide covers maintenance agreements and easements. If a tract is landlocked or access is uncertain, read what landlocked property means before you offer.
For the county-level land view, our Lamar County land and rural property guide and the land and rural hub walk through what to check tract by tract, and the land and ranch service page explains how we evaluate access during due diligence.
