Waterloo, IA Building Safety: Building Permits (2026)

Waterloo City Code section 9-1-1 adopts the 2021 IBC, IRC for One and Two-Family Dwellings, and IEBC as the city's building codes, covering erection, construction, enlargement, alteration, repair, moving, removal, demolition, occupancy, equipment, use, height, area and maintenance of every building and structure in the city. That adoption itself provides for the issuance of permits and collection of fees, so any of those activities on a building or structure triggers the permit requirement unless the work falls on the exemption list the City Council wrote into section 9-1-2.

Waterloo's local amendments to Section 105.2 (IBC) and R105.2 (IRC) exempt only narrow categories: storm window and door installation, broken glass replacement, overhead garage door repair that keeps the same opening size, minor wall repair tied to that garage door work, and exterior arbors no taller than five feet nine inches and no larger than 120 square feet. Detached one-story sheds and playhouses lost their blanket IBC exemption; the IRC version keeps a narrower 120-square-foot, 10-foot-tall exemption for one- and two-family lots. Section 109.2.1 puts permit and inspection fees on a schedule the City Council adopts by resolution (Table 1-B), payable before the permit or re-inspection is issued, and plan review fees under 109.5.1 are due at the time of application. The Building Inspections Department at 715 Mulberry Street administers permits and inspections under the adopted codes.
