Chapter 155: Building Codes
In the August 2026 draft recodification (Building and Property Regulations), from page 301. Current 155 Building Codes.
Comparison with a draft: not adopted. The archive holds no public hearing, ordinance or vote adopting the recodified Code through the October 20, 2026 meeting packet. Until one is adopted, every page here compares the consolidated code with a draft that can still change: the revised draft with the October 6 changes is not in the archive.
A comparison with the August 2026 draft recodification prepared by Iowa Codification for the City. The draft has not been adopted and can still change; the current code (unofficial compilation) governs until a recodified Code is adopted. Matches between sections are made by machine from the texts and are reviewed where uncertain.
The city's explanation
“This is probably the largest substantive section of the codification.”
“The final draft separates the adoption and amendment provisions into individual sections, making the Code much easier to administer.”
