Iowa City, IA Parking Rules: Driveway Rules (2026)

Iowa City Code section 14-5A-5(B), "Paving Materials," sets the citywide standard: all parking and stacking spaces, drives and aisles must be built of asphaltic cement concrete, portland cement concrete or a manufactured paving material like brick. The only built-in exemption covers drives and aisles serving single-family dwellings or duplexes that abut and access historic Woodlawn Avenue or a nonhard-surfaced alley; those may stay unpaved. Everywhere else, the city building official can approve an alternative material only if it forms a durable, permanent surface suited to the use and traffic it will carry, and the code explicitly rules out crushed rock and chip seal as qualifying alternatives no matter how the official rules.

Paving is tied directly to occupancy: section 14-5A-5(B)(3) requires an approved surface in place before a certificate of occupancy is issued. The building official has one narrow escape valve, a temporary certificate of occupancy, available only when paving genuinely cannot be finished because of adverse weather or because the ground is still settling from recent demolition or fill work on the site. Getting that temporary certificate isn't free: the property owner must first deposit an escrow with the city equal to 110 percent of the estimated cost of the paving work, which the city can draw on if the surface never gets finished.

Related design standards in the same article, 14-5A-5(D) and 14-5A-5(C), require paved areas to be pitched or curbed to drain away from streets and neighboring lots and set minimum space and drive dimensions, but the paving-material mandate itself is what governs whether a driveway can be gravel, grass or dirt at all.
