Thornton, CO Sidewalk & Pedestrian Rules: Sidewalk Repair (2026)

This duty comes from Article V of Chapter 10, the South Thornton Urban Renewal Authority Non-Residential Property Maintenance Code, which by its own scope clause applies to existing non-residential structures and premises located specifically in the South Thornton URA area, not citywide (Section 10-236(b)). Within that area, Section 10-250(b) makes the owner of the premises responsible for maintaining structures and exterior property in compliance with the code, while occupants are separately responsible for keeping clean and safe the portions of the property they occupy or control; vacant structures and vacant land must likewise be kept clean, safe, secure and sanitary (Section 10-250(c)).

Section 10-251(c) then singles out sidewalks, walkways, stairs, driveways, parking spaces and similar areas as requiring a proper state of repair, free of hazardous conditions. Enforcement runs through the code official, who must serve a written notice of violation describing the defect and giving a reasonable time to correct it, with the right to appeal spelled out in the notice (Section 10-242). A person cited who disagrees can file a written appeal to the building code advisory board within 20 days of the decision, notice or order (Section 10-246(a)); the board must meet within 20 days of the filing and can modify or reverse the code official's decision by majority vote.
