Driveways for private property at single-family houses are limited to a width of 20 feet for up to a two-car garage and 26 feet for a three- or more car garage. Additional paving is allowed in a front or corner side yard provided the total paved driveway surface does not exceed 33.33 percent of the required yard. For more information, see Article 22.3.2 of the Zoning Ordinance (PDF).
No permit is required for expanding a driveway on private property. However, approval from the City is required for expanding a driveway beyond the maximum width. Please submit a plat of survey showing the proposed expansion to the Building Department for approval before proceeding.
A permit is required for any modifications to a drive approach (also called the “apron,” or the area of the driveway in the public right-of-way, typically between the sidewalk and street). See Sec. 58-71 of the City Code.
