Sioux City Demolition Pros connects owners of placarded, condemned and unsafe buildings in Sioux City with local contractors who can take a structure down before the city does it for them. The city calls the notice a danger posting; owners and the council call it a placard. On April 16, 2026 the council ordered ten placarded properties demolished in a single hearing.
Paying a contractor $8,600 to $19,600 to remove a placarded house on your own schedule is usually cheaper than letting the city demolish it, because the city adds 20 percent to its actual costs and can assess the full bill against the property.
What the Sioux City placard means
Under Chapter 20.06 of the Sioux City Municipal Code, the inspecting official posts a notice reading "Danger, Unsafe or Unfit Structure" on a building that is liable to collapse, is a fire hazard, or is open to people who do not live there. Nobody may enter except to repair or demolish it, and only the official can take the notice down. After the vacate date, gas and electric service can be cut off.
What it costs to clear a placarded house yourself
$8,600 to $19,600
The typical whole-house range from regional cost guides. A building that is partly collapsed, full of contents or carrying asbestos costs more; a small house with no basement sits at the bottom. The permit guide explains the paperwork.
Call (712) 543-5529A placarded house costs about what any teardown costs, plus whatever its condition adds: contents left behind, a collapsed roof that has to be pulled apart carefully, or wet, heavy debris. A single-family house demolished by its owner, or the owner's contractor, to clear the lot is exempt from the state asbestos inspection rule.

Miss them and the official reports the property to the council, which holds a hearing and can authorize the city to demolish it. The ten demolitions ordered on April 16, 2026 were all properties placarded more than six months without the repairs being finished. On those jobs an excavator with a grapple takes the structure down, the debris goes to the landfill, and the basement is filled and graded like any other teardown.
How a city demolition is charged back to the owner
When the city does the work, it bids the job out (sealed bids over $5,000), then charges the actual cost of the demolition, grading, extermination and notices plus 20 percent for administration. The council can assess that total against the property under Iowa Code 364.12, which puts it on the tax bill.
Fourth Street, Pearl Street and Rose Hill
Buildings in Sioux City's historic districts normally need a certificate of appropriateness before demolition, with a commission hearing and council approval. The code exempts a structure deemed unfit for human occupancy, which is often exactly what a placarded building is. Confirm with Inspection Services before you count on it.

Frequently asked questions
Dangerous building demolition in Sioux City, answered
What happens when a house is placarded in Sioux City?
The city posts a danger notice, nobody may occupy the building, and the owner gets a written notice to repair, remove or demolish it. Repairs must start within 30 days and finish within six months; a demolition order must start within 15 days and finish within 60.
What does it cost to demolish a placarded house?
About what any house teardown costs: regional cost guides put it at $8,600 to $19,600, more if the building is partly collapsed or full of contents. If the city does it instead, it adds 20 percent to its costs.
What are the signs the city will order a building demolished?
An open roof, a failing wall, long vacancy, unrepaired fire damage and repeated complaints. In practice the council orders demolition when a placarded building has gone six months without the required repairs.
Can I appeal a dangerous building notice in Sioux City?
Yes, in writing to the Manager of Inspection Services within 15 days of the notice. There is no appeal of a demolition notice that follows a repair notice the owner did not complete.
Will the demolition cost go on my property taxes?
If the city does the work and the bill is not paid, the council can assess the cost against the property under Iowa Code 364.12, which is collected with the property taxes.
