St. Peters, MO Property Maintenance: Property Blight (2026)

Section 113.90.1 defines eleven categories of "dangerous buildings," including structures whose walls lean enough that a plumb line falls outside the middle third of the base, buildings with 33 percent or more damage to a supporting member or 50 percent damage to non-supporting exterior walls, buildings damaged by fire or wind, and buildings so dilapidated they are unfit for human habitation. Section 113.90.2 declares all such buildings public nuisances to be repaired, vacated, or demolished. Under Section 113.90.3.1, the Code Official inspects buildings on complaint or on referral from the Fire or Police Departments, then serves written notice, by personal service, certified mail, or two weeks of newspaper publication if other service fails, on the owner, occupant, lessee, mortgagee, and any other interested party of record with the St.

Charles County Recorder of Deeds. If the owner fails to act within thirty days of a Health and Code Enforcement Manager order following a hearing, the City may repair, vacate, or demolish the building itself and certify the cost as a special tax bill and lien against the property, payable over up to ten years at 8 percent interest under Section 113.90.3.2(e). Appeals go to the St. Charles County Circuit Court within thirty days under Section 113.90.3.3. Where imminent danger exists, Section 112.1 lets the Code Official order the building vacated immediately and post it as unsafe.
