Buying Vacant Land & Building a Home

Start with the intended use

Before you spend money, define what you want to build and what must be possible on the property.

• Identify the intended home type, approximate size, driveway, garage or outbuildings, and your preferred building area.
• Ask whether you need a construction loan, a land loan, or cash for the lot purchase.
• Do not assume a parcel advertised as “buildable” is approved for your particular plans.

Confirm zoning and parcel status

Begin with the local zoning or planning office. This is usually an inexpensive or free first screen for major deal breakers.

• Verify the zoning district, permitted residential use, minimum lot dimensions, setbacks, height and lot coverage requirements.
• Ask whether the parcel is a legally established lot of record and whether any splits, variances, special approvals, or private restrictions may apply.
• Ask what the municipality needs to provide a written zoning or land-use determination.

Review boundaries, frontage, and legal access

Next, check whether the land can legally and practically be reached and where the house could fit.

• Request the legal description and any available survey, parcel map, recorded easements, and title information.
• Confirm public-road frontage or a legally enforceable access easement; ask the road authority about driveway or culvert permits.
• Look for encroachments, utility easements, shared drives, and restrictions that could reduce usable space.

Screen wetlands, floodplains, and drainage

Check available maps and local records before ordering expensive field studies.

• Review FEMA flood maps, state wetland mapping, aerial imagery, and local drainage information.
• Ask the relevant agencies whether wetland delineation, floodplain permits, soil erosion controls, or other reviews may be required.
• Walk the property when conditions allow and look for standing water, low areas, fill, and drainage paths.

Check water, wastewater, and utilities

Utility feasibility can determine whether a parcel works financially or physically.

• Ask whether public sewer and water are available, whether connections are permitted, and what extension or tap fees apply.
• If onsite systems are needed, contact the county health department about septic soil evaluation, permits, well requirements, and required separation distances.
• Contact electric, gas, internet, and other providers about service availability, line extensions, and estimated costs.

Estimate site preparation and construction costs

After the initial screens, get realistic estimates for the work that turns raw land into a homesite.

• Discuss clearing, grading, tree removal, driveway, drainage, foundation conditions, and soil-bearing concerns with appropriate contractors.
• Ask about permits, impact fees, engineering, survey, temporary utilities, and construction access.
• Compare builder availability, house plans, and lender requirements before committing to the parcel.

Order paid investigations in the right sequence

Once the inexpensive checks suggest the plan is viable, invest in property-specific professional work.

• Arrange the survey, title review, and any necessary soils or geotechnical work.
• Complete septic testing, well feasibility, wetland delineation, or environmental assessments as required for the site.
• Obtain written estimates and approvals, and confirm that your purchase agreement provides enough time and appropriate contingencies.

Protect your purchase agreement

A vacant-land offer should reflect the uncertainty involved in determining buildability.

• Discuss feasibility contingencies for zoning, legal access, survey, title, utilities, septic or well approvals, and environmental conditions as applicable.
• Make sure deadlines allow time for agencies, contractors, testing, and lender review.
• Clarify what happens if an approval is denied or a material cost makes the project impractical.

Your next practical step

Before scheduling expensive tests, gather the parcel number, legal description, listing information, and your basic building plan. Ask the municipality about permitted use and lot status, then work through access, environmental screening, and utilities before commissioning detailed investigations.
