Do I Need a Permit for a Driveway?

Most people searching this question are told “check with your city,” which hides the useful answer: a driveway is one of the few projects the building code explicitly exempts, but the parts that touch the street almost never are. The permit you need usually comes from a different agency than the one that issues building permits, and it is triggered by where the work is, not by what it is made of.

This guide explains the model building code exemption, the permits that apply anyway, and how four places handle driveways and curb cuts. If you don’t know which office covers your address, find your local building department.

What the model code says

IRC Section R105.2 lists work exempt from building permits. Item 5 is simply “sidewalks and driveways.” Under the model code, pouring or paving a driveway on your own lot is not building permit work.

Two limits apply:

• The exemption is from the building code only. R105.2 says an exemption does not authorize work that violates “any other laws or ordinances of this jurisdiction.” Right-of-way, zoning, grading and stormwater rules still apply.
• Garage and carport floors are not driveways. IRC R309 requires garage floors to be noncombustible and sloped toward a drain or the vehicle door. Carport floors must also be noncombustible, except that asphalt is allowed at ground level. If you are building a garage or carport, see the garage guide.

The permits a driveway usually needs anyway

Right-of-way, curb cut or driveway approach permit. The apron between the street and your property line is usually public right-of-way. Cutting a new curb opening, widening one, or rebuilding the apron generally requires a permit from the city or county public works or transportation department. That permit sets the apron’s width, thickness, slope across the sidewalk and distance from intersections or neighboring driveways, and the agency inspects it.

Grading or stormwater permit. New pavement sheds water. Some cities require a grading or drainage permit once new or replaced paving passes a set area. Others count driveways toward impervious-cover limits.

Zoning review. Zoning codes often limit driveway width, front-yard paving and parking locations, and they may require the driveway to come off an alley where one exists.

State highway access permit. If your lot fronts a state route, the state department of transportation controls the connection.

Building permit for related structures. A retaining wall along a sloped driveway can need its own permit, especially when it supports the driveway load. See the retaining wall guide.

How the rules differ by city

Four examples, checked against official sources in October 2026:

• Austin. Austin’s residential exemption list covers “a sidewalk, driveway, or concrete flatwork that is not located in the public right-of-way.” Work in the right-of-way needs a driveway/sidewalk permit from Austin Transportation and Public Works. Those permits currently carry a usage fee based on the affected structure, such as the curb, sidewalk or traffic lane. In October 2026 the city reported that City Council would consider, at its October 22 meeting, adding a temporary right-of-way use fee based on the size and duration of the closure.
• Montgomery County, Maryland. A driveway permit from the Department of Permitting Services is required to build a new driveway apron, install a temporary construction entrance, or repair an existing apron on a county road. The county defines the apron as the section from the edge of the roadway to the property line. If the road belongs to the state or a municipality, you apply there instead. You submit a scalable plan, post a refundable construction bond, and hold a pre-construction meeting with the inspector. The county says permits typically issue within 2 to 3 weeks. Under the fee schedule effective July 1, 2026, the filing fee is $186.56 and the permit fee is 18.22057 percent of the estimated project cost.
• Seattle. Seattle handles driveway paving through its grading rules. A grading permit is required to add or replace 750 square feet or more of paving, about 75 by 10 feet. Resurfacing existing paving does not need one. Concrete, asphalt, permeable pavers and compacted gravel you can drive on all count as paving. Projects with more than 5,000 square feet of new or replaced paving must hire a civil engineer.
• Denver. When a residential project includes a new or modified driveway connection or curb cut, city transportation engineers review the condition of the adjacent sidewalks, curb ramps and alley, and the owner may have to improve them. The site plan must show the driveway’s location, width, material, and distance to the property line and neighboring driveways. A driveway onto a state highway needs a Colorado Department of Transportation access permit.

Not every city puts driveways in the building department. In Chicago, driveway permits are handled by the Chicago Department of Transportation, which publishes its own driveway rules and regulations and permit fee schedule.

Work that is often exempt

• Sealcoating, crack filling and resurfacing an existing driveway within your property line.
• Replacing a driveway in the same footprint on private property, below any local grading threshold.
• Small walkways and patios on your own lot, which the model code also exempts as sidewalks.

Any work that removes or alters the curb, gutter, public sidewalk or apron generally needs a right-of-way permit, even a straight replacement.

What inspectors check

Right-of-way inspectors usually look at:

1. Forms and base before the pour: apron width and location, subgrade compaction, base depth and any reinforcement the standard detail requires.
2. Sidewalk crossing: the cross slope where the driveway crosses the public sidewalk, which affects wheelchair access.
3. Curb and gutter: how the depressed curb ties into the existing gutter so water keeps flowing down the street.
4. Final: finished surface, joints, restoration of disturbed lawn or trees, and cleanup of the street.

Montgomery County requires the pre-construction meeting with the inspector before work starts, and Denver may require repairs to neighboring public infrastructure as a condition of the curb cut.

What to have ready when you apply

• Scaled site plan showing property lines, the house and garage, existing and proposed driveways with widths and materials, and distances to the property line, neighboring driveways and the nearest intersection.
• Ownership of the road: whether it is a city, county or state road, which decides who issues the permit.
• Contractor information, plus any bond, insurance or right-of-way registration the agency requires.
• Street tree information: many agencies require a tree protection plan if work affects a roadside tree. Montgomery County may require one.
• Traffic control plan if a sidewalk or lane will be closed on a busy street.
• Paving area calculation to compare against grading, stormwater or impervious-cover thresholds.
• HOA approval, if your covenants regulate driveways.

Call 811 before excavating. Gas, water and communication lines often run under the planting strip and apron.

Questions to ask before you pave

• Is my driveway apron in the public right-of-way, and which agency permits work there?
• What is the maximum driveway and curb-cut width for my zoning district?
• Does replacing or adding paving trigger a grading, stormwater or impervious-cover review, and at what size?
• Will the agency require me to repair the adjacent sidewalk or curb ramp?
• Is a bond or licensed contractor required for work in the street?
• Is my road a state highway?
