Full Breakdown
Driveways in unincorporated Nevada County are regulated where they meet the public road. An Encroachment Permit is required any time work is performed in the County right-of-way that can obstruct the free use of the roadway by the public, including excavation, construction, or placing any structure or object in, under, or over the County roadway, or any activity that may cause water to back onto the road. Driveway design must conform to the Nevada County Department of Public Works Standard Drawings and the County's access standards: at least the first thirty (30) feet of the driveway encroachment from the edge of pavement of the primary roadway must be paved; the driveway must be built to within fifty (50) feet of the nearest point of each dwelling unit; surface width must be ten (10) feet minimum with one-foot shoulders and fourteen (14) feet of unobstructed horizontal clearance for grades up to sixteen percent (16%); and curve radius must be fifty (50) feet minimum from centerline.

Violations & Fines
Performing driveway or right-of-way work without an Encroachment Permit, or building a non-conforming access, is a code violation that can require correction, removal, or permit-after-the-fact; blocking a driveway is cited under CVC 22500(e).
