Council Bluffs, IA Historic Preservation: Historic-Cultural Monuments (2026)

Under CBMC § 16.07.005, the commission weighs eleven designation criteria for any proposed landmark, landmark site or historic district, including whether the property has historical and cultural importance as part of the city's, state's or nation's development, whether it reflects a cultural, political, economic, social or historic heritage, whether it embodies distinctive architectural or engineering elements, and whether it has integrity as a natural environment contributing to the city's quality of life. Designation proceedings start either on the commission's own initiative or by petition of owners holding fifty-one percent or more of the affected area, per CBMC § 16.07.010.

Per CBMC § 16.07.020, the commission must hold a public hearing, then recommend approval, disapproval or modification within sixty days, and transmit its recommendation to the State Historic Preservation Officer within seven days for review and comment. The planning commission then reviews the proposal the same way it reviews a rezoning application, and the city council decides the historic designation and any related rezoning together. Once a property is designated, CBMC § 16.09.010 requires the owner to obtain an alteration permit from the Building Division before any addition, alteration, removal, demolition or other material change visible from outside the structure, covering everything from porch alterations to fence replacement.

Owners must also keep every exterior portion of a designated improvement in good repair under CBMC § 16.10.090, and the commission can order repairs at the owner's expense, with costs assessed against the property, if it finds the structure has become structurally unsound.
