What Permits Do You Need?

A grading permit is required if you add or replace 2,000 square feet (100 feet by 20 feet) or more of paving. If you resurface existing paving you do not need a grading permit. If you remove existing paving and replace it, a grading permit is required once you reach the 2,000 square feet limit. If you do need a grading permit and you are applying for a building permit, your grading activity will be included as part of your building permit.

If you want to pave in or near an environmentally critical area, please contact the Applicant Services Center for coaching.

Should You Hire a Professional?

You may want to hire a professional to help you get your permit. If your project has over 5,000 square feet of new or replaced paving, you are required to hire a civil engineer.
