Yes, inside Sherman city limits a new or rebuilt driveway approach needs a city engineering permit through the Self Service Portal, with a drawing of the approach. On a state highway TxDOT issues the access permit, and on county roads outside town, Grayson County's driveway and culvert rules apply.

Who permits a driveway depends on the road it connects to. Inside Sherman, Development Services issues driveway and sidewalk permits through the Self Service Portal it launched on March 31, 2025, and the permit and drawing must be approved before any inspection is scheduled. The city's drawing criteria ask for the approach width at the property line and at the curb, the flare sizes, the distance from each flare to the nearest property line and curb return, nearby storm inlets, and the water meter location; meters are not allowed inside an approach, the approach should sit 10.5 feet from the nearest drainage inlet unless a variance is granted, and a sidewalk is required unless the Director of Engineering waives it. Sherman's engineering manual adds the geometry: a driveway centerline at 90 degrees to the curb, the drive at least 6 inches above the street gutter where it meets the right-of-way, a residential grade no steeper than 10 percent beyond the right-of-way, and one driveway per residential lot onto a public street unless the City Engineer approves a circular drive. Where a drive meets a state-maintained highway such as US 82, US 377, SH 289, or an FM road, the approach needs a TxDOT access permit whether or not the lot is in a city, and TxDOT's manual sets its angle, width, radii, surface, and drainage. On unincorporated Grayson County land, the county's Development Certificate process covers the driveway: you stake it, the precinct foreman decides whether a culvert is needed and inspects the finished drive, and culvert pipe runs 12 to 36 inches, bought and installed by the owner. The Sherman driveway permits post walks through the three authorities, the driveway thickness guide covers what an approach should be built to, and every driveway scope in Sherman names the permit and who pulls it.
