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

Driveway construction and curb-cut work in Sioux City is governed by two overlapping sources. Title 12 of the Sioux City Municipal Code (Streets, Sidewalks and Public Places) controls work in the public right-of-way, including driveway aprons, curb cuts and sidewalk crossings; the Engineering Division (within Public Works) issues the right-of-way permit and inspects the work. The Title 25 Zoning and Sign Code governs how driveways function on the private lot itself: Section 25.05.030 (Parking and Loading) sets off-street parking, access management, surface and dimensional standards for each zoning district (AG, RR, SR, GR, UR, NC, MU, SC, GC, DC, BP and GI), and Chapter 25.03 (Development Standards) controls setbacks, lot coverage and impervious surface limits that constrain driveway width and placement. Building permits for any driveway-related structure (retaining wall, carport, attached garage) are issued by Inspection Services under Chapter 20.04 (Building Code), which adopts the 2024 International Building Code, 2024 International Residential Code and 2024 International Existing Building Code. The Title 25 framework derives from Iowa Code Chapter 414 (city zoning powers); right-of-way authority derives from Iowa Code Chapter 364 (city home rule) and Chapter 320 (highway authority). ADA accessibility for sidewalk crossings applies under 28 CFR Part 35.
