Driveway / Apron
The paved transition area between a private drive and the public street.
Applies to
New driveways · Driveway widening · Curb cuts · Sidewalk crossings · Garage projects
Project example
A homeowner widening a driveway may need the apron redesigned so it crosses the sidewalk at the required slope without interfering with drainage or a street tree.

Where this term shows up in permit work and how it affects the project
Apron geometry and material standards can trigger right-of-way review even when the private driveway itself does not require a building permit.
If this term appears in a form, plan comment, or local ordinance, start with the building permit guide, compare it against the zoning permit guide, then use the permit guide directory to find the right local path.
Why driveway / apron matters in a permit file
The driveway apron is the transition through the public right-of-way, commonly between private driveway pavement and the street. Its width, slope, curb opening, sidewalk crossing, drainage, and material can be regulated separately from the driveway on private land.
Where it appears in the permit process
Access feasibility
The road authority checks location, spacing, sight distance, street trees, hydrants, utilities, drainage, and the number of allowed curb cuts.
Geometry review
Plans show width, flare, curb treatment, sidewalk cross-slope, grade transition, and how runoff reaches the street or drainage system.
Right-of-way permit
The responsible public agency issues the approval and establishes contractor, material, traffic, and inspection conditions.
Construction verification
Base, forms, reinforcement, curb, sidewalk, finished grade, and restoration may be inspected before and after placement.
What you may need
- Driveway or right-of-way permit application
- Plan showing property line, right-of-way, curb, sidewalk, street, and apron dimensions
- Spot elevations, slope, drainage, and accessibility details when required
- Material, base, reinforcement, curb, and restoration specifications
- Contractor insurance, bond, or registration documents
Where to get it or verify it
- Use the standards of the government that owns the road, not merely the mailing municipality.
- Get right-of-way width, utilities, trees, and drainage information from official plans, GIS, field survey, and the relevant agencies.
- Use an engineer or surveyor when grades, drainage, sight distance, or accessibility cannot be demonstrated on a simple sketch.
Common mistakes that create comments or delays
- Measuring only the private driveway and omitting the apron
- Widening across a hydrant, utility, street tree, or prohibited curb location
- Creating a sidewalk cross-slope or driveway grade that does not meet the standard
- Replacing concrete before the required base or form inspection
What to do next
- Confirm the road owner and right-of-way limits.
- Test the proposed access against location, width, slope, drainage, and utility constraints.
- Coordinate the apron detail with the garage and private-driveway site plan.
- Schedule right-of-way inspections before concrete placement and at restoration.
