North Carolina counties do not have express statutory authority to regulate driveway connections directly, so Wake County itself does not issue residential driveway permits in unincorporated areas. Driveway connections onto state-maintained roads (including most secondary roads in unincorporated Wake County, which carry SR-prefixed numbers under NCDOT maintenance) are regulated by the NC Department of Transportation under N.C.G.S. 136-18(39) and the NCDOT "Policy on Street and Driveway Access to North Carolina Highways." A permit from the NCDOT District 5 Engineer (Wake County) is required for any new driveway connection, change in use, or modification of an existing driveway onto an NCDOT-maintained road. Single-family residential driveways are generally exempt from a formal permit but property owners are still required to coordinate with the District Engineer.
Driveway access in Wake County is governed almost entirely by state and municipal β not county β law. Per the UNC School of Government summary of North Carolina driveway law (Coates' Canons, "What You Need to Know about Driveway Permits and Road Access"), North Carolina counties "lack express statutory authority to regulate driveways directly" and instead influence access only indirectly through subdivision and zoning regulations. Wake County's Unified Development Ordinance therefore does not contain a stand-alone driveway-permit chapter; instead, the UDO regulates driveway location and surfaces only as part of subdivision plat review and as part of the off-street parking setbacks that apply within each zoning district.
The operative rule for almost all unincorporated Wake County properties is therefore the NC Department of Transportation's "Policy on Street and Driveway Access to North Carolina Highways" (2003, periodically amended), adopted under N.C.G.S. 136-18(39). Most secondary roads in unincorporated Wake County carry an "SR" prefix and are maintained by NCDOT, which means any new driveway connection onto those roads requires NCDOT review. Applications for street and driveway access permits in Wake County are filed with the NCDOT District 5 Engineer at the Wake County office (919-733-3213). The application form (TEB-65-04) and the permit-submission user guide are published on the NCDOT Connect portal.
NCDOT's Policy on Street and Driveway Access requires each driveway connection to: (a) provide adequate intersection sight distance based on the posted speed of the road; (b) be located so that the sight-distance triangle is clear of obstructions; (c) be aligned roughly perpendicular to the road centerline (commonly within Β±15 degrees of 90); (d) include a NCDOT-specified drainage culvert sized to the road's open ditch; and (e) tie to the road at the existing pavement grade with an acceptable approach slope. For developments expected to generate more than 3,000 vehicle trips per day, NCDOT requires a Traffic Impact Analysis; for more than 4,000 trips per day, NCDOT may require the applicant to fund acceleration/deceleration lanes, turn-storage lanes, or median improvements (per the 2012 Supreme Court decision in High Rock Lake Partners, LLC v. NCDOT, those conditions must relate specifically to the driveway connection itself).
Single-family residential driveways are an important practical exception. NCDOT's Driveway Permit FAQ explicitly states that "permits are normally not required for a single residence," but encourages property owners to contact the District Engineer to coordinate driveway-pipe installation, identify safety and design issues, and avoid conflicts with planned highway projects. Homeowners building a single-family driveway in unincorporated Wake County should therefore still call NCDOT District 5 at the front end. For driveways onto streets inside one of Wake County's incorporated municipalities (Raleigh, Cary, Apex, Wake Forest, Garner, Holly Springs, Morrisville, Knightdale, Wendell, Zebulon, Fuquay-Varina, Rolesville), the municipal engineering or public-works department issues the permit, and where a state road passes through a municipality both NCDOT and the city may regulate the connection β "the more stringent requirement shall apply" (G.S. 160A-307).
Constructing a driveway connection to a state-maintained road in Wake County without an NCDOT permit (where one is required) is an unlawful encroachment on the public right-of-way under N.C.G.S. 136-93. NCDOT may require the unauthorized work to be removed at the owner's expense and may withhold approval of any related building or development permit until the violation is corrected. Where a Wake County subdivision plat conditions lot approval on demonstrated driveway access, an owner who fails to obtain a required NCDOT permit may also be unable to record the plat or close on the lot. Cities may impose municipal civil penalties under their own driveway ordinances for connections to city streets.
