Do I Need a Permit for a Driveway?
For the driveway on your own property, usually a simple permit or none at all — but the driveway approach (the apron crossing the sidewalk and curb) almost always requires a right-of-way permit from the city or county. That apron work is in the public right-of-way, affects drainage and sidewalks, and must meet accessibility standards. Skipping the ROW permit is the most common driveway violation.

The right-of-way permit
Cutting the curb, pouring the apron, and connecting to the street all happen in the public right-of-way and need an encroachment or ROW permit — typically $100-$500, sometimes with a refundable deposit against sidewalk damage. The city specifies the apron dimensions, concrete thickness, and reinforcement; some require the sidewalk to remain continuous through the driveway (no dip). Work without the permit risks a stop-work order and removal.
Drainage and grading
Driveways change site drainage: the civil concern is that your new impervious surface does not send water onto the neighbor or overwhelm the street gutter. Steep driveways need drainage intercepts; driveways sloping toward the garage need a trench drain at the threshold. In hillside areas, driveway grading and retaining walls often need engineered plans beyond the basic permit.
Width, setbacks, and HOA rules
Zoning limits driveway width (often 20-24 feet max in residential zones) and the percentage of front yard that can be paved. Circular driveways need two curb cuts — each permitted separately. HOAs frequently dictate materials, colors, and patterns. And circular or widened driveways that remove street trees trigger the city's urban forestry review — a separate permit with its own timeline.
The bottom line
The on-site driveway is simple; the curb-cut apron in the right-of-way needs a city permit. Handle drainage, respect width limits, and check HOA and tree rules before pouring.
