Land Development Feasibility Study
Before you buy land, an engineer checks zoning, utilities, access, flood zones, soils and costs to see what can actually be built.
What the work involves
A due diligence or feasibility study reviews a parcel's zoning, setbacks, utility availability and capacity, road access, floodplain and wetland constraints, soils, topography and permitting path, then estimates a buildable area and order-of-magnitude site costs. It often includes a conceptual site layout or lot yield. The result helps a buyer or lender decide whether the price makes sense and what approvals will take before the purchase closes.
Local conditions we plan for
- Deep frost penetration
- Heavy snow loads
- Great Lakes shoreline erosion
- Karst in the southwest Driftless Area and Door County
Building code: IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026).
When you need it
- Considering buying raw land or a redevelopment site
- Need to know how many lots or how much building area fits
- Unclear whether water, sewer or road access is available
- Parcel may contain wetlands, floodplain or steep slopes
- Lender or investor wants a due diligence report
Frequently asked questions
How much does land Development Feasibility Study cost?
Across the US, land Development Feasibility Study usually costs $2,500 to $25,000. Estimate. Small single-lot checks can be a few thousand dollars; multi-acre commercial due diligence with a conceptual plan and agency meetings costs more. Surveys, Phase I ESA and geotechnical work are usually separate.
How long does land Development Feasibility Study take?
Plan on 2 to 6 weeks, often timed to the purchase contract due diligence period from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Is a permit required for land Development Feasibility Study?
Often not on its own, but the findings frequently lead to work that does need a permit. We tell you which parts of the follow-up work your local building department will review, and can prepare those drawings too.
How do I verify an engineer's license in Wisconsin?
Engineers practicing in Wisconsin are licensed by the Wisconsin Examining Board of Architects, Landscape Architects, Professional Engineers, Designers and Professional Land Surveyors. You can confirm a license number and its status in the board's public license search before you sign a contract.
How deep is the frost line in Wisconsin?
Wisconsin Uniform Dwelling Code SPS 321.16 requires footings to be below frost penetration or at least 48 inches below adjacent grade, whichever is deeper (one and two family dwellings). Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.
Which building code applies in Wisconsin?
IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
