Concrete Driveways & Sidewalks in Milton, WA

Driveways & sidewalks in Milton: what to know

Milton’s published public works standards put numbers on driveways. A residential driveway is capped at 20 feet wide, or 30 feet for a three-car garage if the Public Works Director approves. Grade is limited to 12 percent unless the director allows otherwise, the driveway must meet the street at 60 degrees or more, and the apron cannot extend past the face of the curb. Runs over 150 feet need the fire marshal’s approval too.

The zoning code adds its own limits. Driveways count toward the impervious surface cap for your zone, a single-family home needs two off-street spaces, and a clear sight triangle has to stay open at the driveway mouth. If you are adding an accessory dwelling unit, its parking is counted per bedroom unless transit is close.

Permits and rules in Milton

Driveway work on your own lot is reviewed by the City of Milton’s planning and community development staff. Anything in the public right-of-way, including the approach, apron, curb, and sidewalk, needs a separate street work permit from Public Works, and the owner is expected to maintain the approach afterward. The city’s standards bar monolithic curb, gutter, and sidewalk pours and call for an inspection of forms and subgrade first. We check Milton’s apron and approach rules before a driveway goes on the schedule.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

Questions from Milton homeowners

How wide can I make my driveway in Milton?

The public works standards cap a residential driveway at 20 feet, with 30 allowed for a three-car garage if the director approves. Impervious surface limits also count, so a wider driveway can use up room you may want for a patio. We check both before we draw it.

Do I need a permit to replace my sidewalk apron in Milton?

The apron sits in public right-of-way, so replacing it needs city approval, and the city inspects forms and subgrade before the pour. We ask the city which permits apply and tell you before we quote.

My Milton driveway is steep. Is there a grade limit?

The public works standards set a maximum grade of 12 percent unless the Public Works Director approves a different grade in writing. We measure the existing grade first and see what the city would accept.
