Land Due Diligence Checklist

1. Property identity and parcel verification

Confirm the APN, legal description, recorded acreage, county, and current owner of record against the assessor and recorder — not the listing. Make sure the parcel being sold is the parcel on the record, and note whether an approval or utility claim depends on more than one parcel.

2. Legal and physical access

Legal access means recorded public road frontage or a recorded easement. Physical access means a usable route that actually reaches the buildable area, year-round, for construction vehicles. Check both. Private-road maintenance agreements and seasonal closures matter as much as the easement itself. Landlocked parcels stay a red flag until access is confirmed in writing.

3. Zoning and permitted uses

Verify the zoning district, overlays, permitted and conditional uses, density, manufactured-home and ADU rules, and any HOA or subdivision covenants. A numeric zoning field on a listing is not a zoning determination — confirm the named district with the planning department, the zoning map, and the ordinance.

4. Buildability and setbacks

Identify the usable building envelope after setbacks, frontage requirements, minimum lot size, slope, and unusable ground. A 10-acre parcel with 6 acres of steep ravine is not a 10-acre deal. Confirm what can actually be built and where before pricing the property.

5. Survey, boundaries, plats, and easements

Look for an existing survey or recorded plat, and review recorded easements, encroachments, and boundary disputes. Online parcel maps are a research starting point, not a boundary determination. On parcels where boundaries or access are unclear, a current survey is usually worth the cost.

6. Utilities, water, sewer, septic, and power

Determine whether power is at the parcel or requires an extension, what the water source will be (municipal, shared, or well), and whether sewer connection or a septic system is required. Availability is not capacity — request written confirmation of service, capacity, connection fees, and impact fees from the utility provider or public works department.

7. Flood, wetlands, drainage, slope, and environmental concerns

Review FEMA flood zones, wetlands designations, drainage patterns, erosion, and topography. Also look for contamination signs, old dump sites, debris, prior industrial use, wildfire exposure, and nuisance uses next door. Mapped data is a prompt to investigate, not a verdict — see how to check FEMA flood zones before buying land for the zone-by-zone walkthrough.

8. Title, deed restrictions, liens, and recorded documents

Confirm the seller matches the owner of record, then review unpaid taxes, liens, judgments, deed restrictions, and probate, trust, or estate complications. Pull the recorded documents behind any approval or development agreement. Title problems are often fixable — but only when they are found before money is committed.

9. Comparable sales and preliminary value

Compare the asking price against recent closed vacant-land sales in the same area and size band, adjusted for access, utilities, and buildability — not against other hopeful asking prices. Use comps to establish a preliminary price-per-acre and value range before you negotiate.

10. Subdivision or land-split potential

If the plan involves splitting, confirm minimum lot size, frontage, access, and wastewater rules for each proposed lot, plus the county's process for a minor subdivision. Split potential only counts once the rules support it.

11. Development costs and deal numbers

Budget surveying, engineering, utility extension, septic or well, driveways and road improvements, permits, and impact fees alongside the purchase price. Then run the deal math for your intended exit — hold, flip, split, or develop — and identify the walk-away price.

12. Final verification with agencies and professionals

Close the loop in writing with planning and zoning, public works, the road department, the health district, the utility providers, and your title company, surveyor, engineer, and attorney. Anything still unverified should be treated as an open question, not as a fact.

Trusting the listing description

Listing copy is marketing. It may be accurate, but it often omits problems or uses vague language about access, zoning, utilities, acreage, and flood status. Verify every material claim against county records and the provider.

Treating availability as capacity

A water or sewer line near the parcel does not mean service is available to it. Ask the provider for written confirmation of capacity, connection requirements, and fees.

Assuming an approval transfers

Site-plan approvals and development agreements can expire, carry conditions, or depend on more than one parcel. Read the adopted documents and the full parcel list before paying for the approval.

Structured analysis flow

LandGauge organizes the parcel review into the same categories as this checklist, so important checks do not get skipped under deal pressure.

Direct county and GIS links

Each review surfaces the relevant county GIS, zoning, and planning resources for the parcel, so you can verify the items on this checklist without hunting for them.

Evidence and open questions tracked

Findings are recorded as verified, assumed, or still needing verification, so the unverified items stay visible instead of quietly becoming assumptions.

Risk, split potential, and exit math together

Risk flags, split potential, and deal economics live alongside the property record, so you can review the parcel as a whole instead of in pieces.
