Des Moines adopts its construction codes by municipal ordinance and supplements the model building-code framework with local administrative, zoning, site-development, and right-of-way requirements. The City’s adopted-code and amendment materials, rather than a generic I-Code alone, control the permit submittal.

The metro’s active work includes data centers and other power-intensive development, logistics and industrial facilities, healthcare and higher education, and office or mixed-use redevelopment. Insurance and financial-services employers remain an important local commercial base, while greenfield projects at the metro edge bring substantial utility and stormwater planning.

Des Moines Engineering FAQs

Who reviews commercial permits in Des Moines?
The City of Des Moines Permit and Development Center administers building and trade permitting. A commercial project can also need fire, zoning, site, stormwater, utility, and right-of-way review, so those requirements should be coordinated with the building submittal.
Which building and energy codes apply in Des Moines?
Des Moines adopts the 2021 IBC through its Building Code with City amendments. Commercial energy compliance follows Iowa’s Energy Conservation Code based on the 2021 IECC with Iowa amendments; the City's adopted-code materials govern the specific permit path.
Who provides utilities, and what site risks matter?
MidAmerican Energy provides electric service, Des Moines Water Works provides water, and the City manages sanitary sewer and stormwater systems. Cold winters, tight or variable soils, and Des Moines/Raccoon River floodplain conditions make early utility, geotechnical, and drainage coordination important.
