Sioux City Demolition Pros connects Sioux City lot owners and builders with local crews who remove old foundations: the slab of a torn-down garage, the block or brick walls of a house basement, and footings left behind by an earlier teardown. On many city lots, the last demolition left more in the ground than anyone recorded.
Removing an old slab at $2,000 to $6,000 before you build costs far less than finding buried footings and rubble after the new foundation is designed, when every surprise becomes a change order at $3 to $5 per square foot for basement removal.
What is usually under a Sioux City lot
Older houses here sit on brick, rubble stone or early block foundations, and some lots have been built on twice. When a house was demolished decades ago, the walls were often pushed into the basement and covered over. Builders find old footings, cisterns and broken concrete when they dig for the new house.
Foundation removal cost, slab versus basement
$2,000 to $6,000
HomeGuide's national range for removing a concrete slab foundation, $1 to $3 per square foot. Basement foundations run $3 to $5 per square foot because they need major excavation.
Call (712) 543-5529A slab is broken in place and hauled; the cost follows its area and thickness. A basement is a bigger job: the walls are broken out, the floor is broken or drilled to drain, and the hole is either filled or opened for the new foundation. Rebar, a thick footing and tight access all add time.
- Slab foundation: $1 to $3 per square foot (HomeGuide).
- Basement foundation: $3 to $5 per square foot (HomeGuide).
- Tractor backfilling: $3 to $6 per cubic yard (HomeGuide).
What Sioux City's code expects of the hole
The city's demolition rules say the excavation is filled in a way that removes any danger, and its grading rules set the standard for that fill: layers no thicker than eight inches, compacted, free of broken concrete unless the approved plan allows it, and a grading permit once more than 50 cubic yards moves. Fill deeper than five feet needs an addendum recorded with the county.
Building on the spot afterwards
Fill placed with no plan for a building can be compacted to a lower standard, but only if the owner acknowledges in writing that the site is not suitable for construction without soil testing. If a new house is planned, say so up front so the fill is placed and compacted to support it, or left open for the new foundation.

Frequently asked questions
Foundation removal in Sioux City, answered
How much does concrete foundation removal cost in Sioux City?
HomeGuide's national figures put a slab foundation at $2,000 to $6,000, or $1 to $3 per square foot, and a basement foundation at $3 to $5 per square foot. Thickness, rebar and access move it.
Can I leave the old foundation in the ground?
Some owners leave walls collapsed below grade under a lawn, but for any new building the old concrete and brick should come out so the new footings sit on inspected soil.
What are the signs of an old foundation buried on a lot?
Concrete or brick hit during digging, uneven settling in the lawn, and records of an earlier house on the lot. A test pit before you design the new foundation finds it cheaply.
Do I need a grading permit to fill an old basement in Sioux City?
If the work moves more than 50 cubic yards of material, yes. A typical house basement can pass that, so ask the contractor to include the grading permit.
Can broken concrete from the foundation go back in the hole?
Only if the approved grading plan allows it. Sioux City's grading standard otherwise keeps broken concrete, asphalt and large rocks out of fill.
