Can you build on that lot? A due-diligence checklist

Identify the parcel and the decision deadline

Confirm the parcel number, legal description, seller-provided documents and the land included in the transaction. Save a map for orientation, but obtain a survey appropriate to the project instead of using a marketing outline as a measured boundary.

If you are considering a purchase, give the relevant professionals the actual contractual due-diligence deadline. Decide which unanswered questions would cause you to pause, renegotiate or walk away. A checklist only helps if findings arrive while you still have meaningful choices.

Check the usable building area

Ask the planning authority about the proposed use, setbacks, height, coverage and any other controls applicable to the parcel. Have the design team place the potential home, driveway, equipment and required site features on a reliable base plan. Do not assume that a neighboring house establishes what you can build.

Request review of easements, access rights and recorded restrictions by the appropriate professionals. A parcel can look spacious while the practical building area is constrained. Keep the survey, title information and planning responses together so one professional’s assumptions can be checked against another’s.

Verify services instead of assuming availability

Ask each relevant provider for the connection point, capacity review, owner responsibilities and a current basis for pricing. A utility line visible nearby does not tell you what the connection will require.

• Water source and service connection requirements
• Wastewater connection or the feasibility of the applicable onsite system
• Electric service route, equipment and capacity review
• Access from the public road and any driveway approvals
• Communications services and any easements needed for installation
• Who restores disturbed areas and pays applicable connection charges

Investigate the ground and water

FEMA identifies its Map Service Center as the official public source for National Flood Insurance Program flood-hazard information. Use the current parcel-relevant mapping with the local floodplain administrator; do not treat an online map screenshot as a complete design assessment.

Ask whether a geotechnical investigation, elevation information, drainage study or environmental assessment is appropriate. Trees, wetlands, previous fill, buried debris and access limitations belong on the risk list. Qualified specialists should determine the investigations and interpret the findings. Do not clear or disturb a site just to make it easier to inspect.

Create a buildability decision sheet

Summarize each issue in four columns: evidence obtained, unresolved question, responsible professional and cost or schedule implication. A useful conclusion is specific, such as “utility provider response pending” or “concept footprint requires revision,” rather than a blanket statement that the lot is buildable.

Separate the land price from investigation, design, approvals, site preparation, servicing and construction. Obtain a project-specific review before making a commitment that depends on development potential. This guide is educational and does not establish a particular parcel’s feasibility or imply that every builder provides land-development services.
