Ames, IA Parking Rules: Driveway Rules (2026)

Ames Municipal Code Sec. 29.307(5), part of the Zoning Ordinance's nonconformities article, addresses two related situations. Under subsection (e), Single- and Two-Family Home Driveways and Paving, front yard paving already in place before January 1, 2023 that does not meet current standards is pre-existing and does not have to be removed or replaced unless the principal structure on the lot is replaced and the required parking location can then be accommodated under current standards. Subsection (f), Unpaved Driveway, Parking, Vehicle Maneuvering Areas, lets an existing unpaved driveway, approach, parking area, or vehicle maneuvering area continue to be used and maintained as nonconforming.

Paving is triggered, however, the moment the area is lengthened or widened, is needed to serve a new use's required parking, the parking area is moved or replaced, or a new garage is built or an existing garage or parking space is reconstructed or added to. Once triggered, the property owner must obtain a Driveway Permit that conforms to the City's Article 4 development standards before the surface can be brought into paved compliance. The rule applies citywide to single- and two-family residential lots and is administered by the Planning and Housing Department's Zoning Enforcement Officer, who reviews Driveway Permits and site development plans.

Because Chapter 29 makes any violation of its provisions a municipal infraction under Sec. 29.1603(7), a property owner who paves without a permit, or who fails to pave after a trigger event, faces a $500 civil penalty for a first offense and $750 for each repeat violation, separate from the requirement to still bring the surface into compliance.
