Is a permit needed to widen or install a new driveway?

No permit is required. However, the Planning Division requires a site plan - even if the new driveway is exactly identical to the old driveway. The site plan should show the location of the property lines, house, garage and existing driveway, location of the new driveway, how it will be widened, and length/width dimensions. If the proposed driveway meets all city requirements, an approval will be made. No inspection is required.
