St. Louis County, MO Property Maintenance: Property Blight (2026)

Chapter 1110 is organized so that each exterior element has its own section, which matters because a Notice of Violation cites the specific one. Protective treatment is §1110.303.2, and its wording is a repair-and-repaint duty rather than a cosmetic preference: peeling, flaking, and chipped paint must be eliminated and the surfaces repainted, so scraping alone does not close the case.

Exterior structure is §1110.303.10, and it covers more than shingles. Roofs must be kept in good condition with no loose shingles and no deteriorating fascia and soffits. Roofs must be constructed with quality roofing materials and assembled plumb, and chimneys must have proper flashing and tuck pointing. That last clause is the reason a chimney with open mortar joints can be cited even when the roof field itself is sound. Guttering, decks, and porches are cited under the same section.

The rest of the exterior is spread across neighboring sections: foundations at §1110.303.5, sheds and other accessory structures at §1110.302.7, sidewalks at §1110.302.3, and windows and doors at §1110.302.15 and §1110.303.13. The split between the 302 and 303 series tracks the difference between the premises around the building and the building's own exterior.

Enforcement runs by complaint through the Neighborhood Preservation Program rather than by routine sweep, so a violation typically starts when a neighbor calls. The cure window on a Notice of Violation is 7 to 30 days, and where a case falls in that range depends on how hazardous the condition is: a structural or safety problem gets the short end, a paint or gutter case the long end.
