Summary

Sioux City can post, order repaired, or demolish any dangerous or dilapidated building, fence, or structure that endangers health, safety, or public welfare, assessing demolition costs against the owner and property.

Whenever the inspecting official determines that any structure is a dangerous or dilapidated structure, the inspecting official shall:

1. Cause to be posted in a conspicuous place on the structure a notice which shall read substantially as follows: "Danger - Unsafe or Unfit Structure." Such notice shall remain posted until the required repairs, removal or demolition is completed. Such notice shall not be removed except by the inspecting official or by the inspecting official's written permission and no persons shall enter a building except for the purpose of making the required repairs, removal or demolition.

2. Cause to be served upon the owner thereof and the occupants, if any, a written notice which shall contain:

a. The street address and a legal description sufficient for identification of the premises upon which the structure is located;

b. A statement that the inspecting official has found the structure to be a dangerous or dilapidated structure with a description of the conditions found to render the structure dangerous under the provisions of Section 20.06.020;

Full Breakdown

Chapter 20.06 defines a dangerous or dilapidated structure as any building, shed, fence or other man-made structure that is a health hazard, a fire hazard, at risk of collapse, or open to trespass because of missing doors or windows. Once the inspecting official makes that finding, the structure is posted "Danger - Unsafe or Unfit Structure" and the owner and occupants get written notice ordering repair or demolition, with repair work due to start within 30 days and finish within six months, or demolition to start within 15 days. An owner may appeal to the Inspection Services manager within 15 days.

Violations & Fines

Failure to comply lets the city report the owner to the city council, which after a hearing may order city-performed demolition and assess all costs against the owner and the property under Chapter 20.06.
