Draft chapter 166: Establishment of Zoning Districts and the Official Zoning Map
§ 166.09 Residential District Medium-Density Two-Family (R-2)
The 2026 draft's § 166.09 beside the current code's Zoning § R-2.01, Zoning § R-2.02, Zoning § R-2.03, Zoning § R-2.04, Zoning § R-2.05, Zoning § R-2.06, Zoning § R-2.07, Zoning § R-2.08, Zoning § R-2.09, Zoning § R-2.10: removed words are struck through, added words underlined.
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.
Merged wording changed (81% same words)
Ord. 2013-333, 2017-393 amend this part of the current code in ways not read to its sections: some differences may come from those ordinances, not from the draft.
