On land outside city limits, a driveway that connects to a county road needs a county permit in Crook and Jefferson Counties. Crook County requires one before you create access to a county road (CCC 12.04). Jefferson County requires a driveway connection permit before you build a new driveway onto a county or local access road (JCZO 17.401.5). For Deschutes County, confirm the access requirements with the county. Inside a city, the city’s rules apply.
Who decides
Which road your driveway meets decides which office you ask. In Crook and Jefferson Counties, a county road means a county permit (CCC 12.04, JCZO 17.401.5). In Jefferson County, access to a state highway needs ODOT approval instead (JCZO 17.401.5).
For lots outside city limits, approval is the county’s decision. Inside city limits, the city decides.
What each county says
Crook County
Crook County requires a county permit before you create access to a county road or dedicated public road (CCC 12.04). The application goes to Crook County Planning. The county roadmaster reviews it and does a final inspection. The access has to be built within 6 months of approval.
Jefferson County
Jefferson County requires a driveway connection permit before you build any new driveway onto a county or local access road (JCZO 17.401.5). Access to a state highway needs ODOT approval instead.
The county’s road design standards also set a 12 percent maximum grade for a residential driveway and a 12 inch minimum culvert (JCC 12.18.210 and 12.18.220). Confirm the current standard for your road before you design.
Deschutes County
Confirm the access requirements for your lot with Deschutes County before you plan the driveway. Ask whether your road is a county road, because the answer tells you which office approves the access.
Walk the access point first
Mark where the driveway will meet the road, then sketch the path to the house. That spot can change where the house sits.
Check where your lot line ends. It can stop a few feet short of the edge of the road. The driveway still has to reach the pavement, so plan for the extra length.
Measure the grade from the road to the house site. Steep driveways cause trouble with break-over and approach angles. The SiteFacts Slope Calculator gives you percent grade from two elevation readings and the distance between them.
If the driveway slopes toward the garage, plan the drainage before anything gets poured. Ask your builder or the county what fits your lot.
Width, materials and culvert details come from whoever owns the road. A neighbor’s driveway is not a reliable guide, so ask the office that issues your permit.
Trucks also need a solid gravel base to reach the site. Ask your builder how the driveway will be used during construction.
Fire trucks need to reach the house too
Oregon adopts a statewide fire code, the 2025 Oregon Fire Code based on the 2024 International Fire Code (OAR 837-040-0010). It sets how close a fire truck must be able to get to a building. Local fire districts apply it, and some have State Fire Marshal approved local provisions. Confirm the access requirement with the fire district that serves your lot.
Jefferson County adds its own fire safety standards for new construction in unincorporated areas (JCZO 17.426.2). They include emergency vehicle access to within 50 feet of all buildings, with a 12 foot surface, a 75,000 pound capacity and a 10 percent maximum grade unless the fire chief approves. That fire access limit is lower than the 12 percent driveway standard above, so confirm with Jefferson County which limit governs your driveway and the other details for your lot.
