Site Prep in Montana
Everything between raw land and a buildable pad: clearing, stripping, cutting, filling, compaction and the construction entrance.
Project guide
Site preparation is the package of work that turns a lot into a place a builder can start. On a typical job that means clearing vegetation, stripping and stockpiling topsoil, cutting or filling to the pad elevation, compacting fill in lifts, cutting in a temporary driveway, and installing the silt fence and gravel entrance the stormwater inspector expects to see. The scope shifts with the ground: a flat suburban infill lot may take two days, while a sloped wooded parcel with poor soil can run weeks and involve undercutting and replacing unsuitable material. Site prep contractors typically coordinate with the surveyor who sets the corners and the geotechnical engineer who signs off on compaction.

Listed businesses are based in Belgrade, Havre, Libby, Anaconda, Kalispell, Columbia Falls, though most crews travel well beyond their home city.
A straightforward residential lot typically runs $3,000 to $15,000 for clearing, stripping and pad grading, with heavily wooded, sloped or poorly drained parcels going well past that. Imported structural fill adds $10 to $30 per cubic yard delivered, and undercutting bad soil is one of the most common change orders on a site prep job.
Ranges are national and approximate; regional labor rates, material prices and site conditions move them in both directions.

Send the site plan, the survey with pad elevations, any geotechnical or soil report, and the order the trades will arrive so the contractor can leave the site the way the foundation crew needs it.
The main cost items are vegetation and debris on the lot, and whether it is chipped, burned, hauled or buried on site; volume of cut and fill, the lift thickness and compaction spec, and whether a testing lab is required; slope, access, drainage across the lot, weather windows and how much room there is to stockpile. A site visit helps the crew see which ones apply.
Site prep usually runs under the main building permit, but grading, land disturbance and stormwater permits are often separate and must be in hand before the first tree comes down. Lots on a public road need a driveway access permit for the construction entrance.
