Like all U.S. states, Maryland driveway permit requirements are governed at the local level — by state DOT for state highways, by county or regional authorities for county roads, and by cities and municipalities for local streets. There is no single statewide permit for residential driveways. This guide explains how the system works in Maryland and how to find the right agency for your address.
Key rule in Maryland: Any driveway connection to a public road — regardless of whether it's city, county, or state — requires a right-of-way permit from the managing authority. The private-property portion may additionally require a local building permit.
How to Find the Right Permit Authority in Maryland
- State highway (numbered US or State Route): Contact your state DOT district office. In Maryland, this is the state transportation agency. They issue access or encroachment permits for all state-maintained roads.
- County road: Contact your county's public works or engineering department. County roads in Maryland are maintained by county government; access permits come from the county engineer or road department.
- City or municipal street: Contact city hall or the city's public works / engineering department. Every city in Maryland with its own street network issues its own driveway permits.
- Not sure which type? Call your county engineer's office and give your address. They'll confirm who has jurisdiction.
Typical Maryland Permit Fee Ranges

| County road | $25–$100 | 1–2 weeks |
| City/municipal street | $50–$200 | 3–7 days |
Fees and timelines are general estimates. Individual counties and cities in Maryland set their own fee schedules. Call the specific agency for exact current fees.
Culvert Requirements in Maryland
On county and rural roads in Maryland that use open ditch drainage rather than curb-and-gutter systems, a culvert is required under any new driveway crossing a roadside ditch. The county engineer specifies the required pipe size, material, and length. Do not order culvert materials before getting the specification — undersized or wrong-material culverts fail inspection and must be replaced.
Same-Footprint Replacement Rules in Maryland
Rules on same-footprint driveway replacement (replacing a driveway with the same size, same material, same location) vary by city and county in Maryland. Many municipalities exempt the private-property portion from permit requirements for same-footprint replacements. The apron (ROW portion) typically requires a permit even for replacement. Call your local public works office and describe the specific project to get a definitive answer.
Maryland Driveway Permit FAQ
Do I need a permit to pave my driveway in Maryland?
For the apron (the connection to the road), almost always yes. For the private-property portion, it depends on your specific city or county. The safest approach is to call your local permitting authority and ask before starting any work. Most will give you a quick verbal answer at no charge.
What's the easiest way to find out exactly what's required for my address in Maryland?

This single call typically answers all your jurisdiction questions. Alternatively, use the Permit Checker Tool for a general estimate before you call.
How long do driveway permits last in Maryland?
Most residential driveway permits in Maryland are valid for 6 months to 1 year from the date of issuance. Work must be completed and inspected before the permit expires. If your project is delayed, contact the issuing agency to request an extension before the permit lapses.
