Vacant Land Due Diligence Checklist: What to Check Before You Buy

Vacant land looks simple: no house to inspect, no tenants, no roof. That's exactly why buyers skip steps. A parcel without legal access, without a buildable septic site, or sitting in mapped wetlands can be worth a fraction of what you paid. Use this checklist on every parcel, even inexpensive ones.

1. Confirm the parcel itself

• ☐ Look up the parcel number (APN) on the county GIS map.
• ☐ Download the assessor record: owner, acreage, assessed value, tax status.
• ☐ Get the deed and legal description from the county recorder.
• ☐ Compare acreage across GIS, assessor, and deed.
• ☐ Order a survey if boundaries, acreage, or encroachments matter to your plans.

GIS lines are approximate. If you're splitting, building close to a line, or paying by the acre, a survey is worth it.

2. Legal and physical access

• ☐ Confirm road status with the county road department.
• ☐ Ask the title company to identify access easements in the title commitment.
• ☐ Visit or have someone visit to confirm the road exists and is usable year-round.

Warning: A dirt track on satellite imagery isn't legal access. Without public frontage or a recorded easement, lenders, buyers, and building departments may treat the land as landlocked.

3. Zoning and permitted uses

Ask the planning department, in writing if possible:

• ☐ What's the zoning for parcel [APN]?
• ☐ Are single-family homes, manufactured homes, tiny homes, RVs, and camping allowed? For how long?
• ☐ What are the minimum lot size, road frontage, and setbacks?
• ☐ Can a building permit be issued given the parcel's size and access?
• ☐ Are there overlay districts (floodplain, conservation, airport, historic)?
• ☐ Can the parcel be split, and how?

4. Utilities

Line extensions can cost thousands of dollars or more depending on distance and terrain. Get estimates in writing for any parcel you're buying as a homesite.

5. Septic and soils

• ☐ Check soil types and septic limitations on the USDA Web Soil Survey.
• ☐ Ask the county health department whether a perc test or soil evaluation is required, the typical cost, and whether nearby parcels have septic permits.
• ☐ Ask whether engineered or alternative systems are allowed and what they cost.

6. Flood zones and wetlands

• ☐ Check the FEMA Flood Map Service Center for flood zone designation.
• ☐ Check the U.S. Fish & Wildlife Service National Wetlands Inventory for mapped wetlands.
• ☐ Understand that building in a special flood hazard area adds permits, elevation requirements, and insurance costs, and that filling wetlands may require federal and state permits.

7. Restrictions, covenants, and associations

• ☐ Read every recorded covenant, condition, and restriction listed in the title commitment.
• ☐ Look for bans on manufactured homes, RVs, livestock, or further splits; minimum home sizes; architectural review.
• ☐ If there's an HOA or POA, get dues, rules, and an estoppel letter showing anything owed.

8. Title, liens, and back taxes

• ☐ Order a title commitment or attorney title examination.
• ☐ Identify every owner of record; confirm all are alive and able to sign, or that an estate representative can sign.
• ☐ List mortgages, judgments, tax liens, and HOA liens to be paid at closing.
• ☐ Check for severed mineral, oil and gas, or timber rights.
• ☐ Ask the county treasurer about delinquent taxes and any scheduled or completed tax sale.
• ☐ Buy an owner's title insurance policy.

9. Environmental and physical red flags

• ☐ Dumping, abandoned vehicles, drums, or old tanks.
• ☐ Former industrial, agricultural chemical, or fuel storage use.
• ☐ Steep slopes, rock, ravines, or erosion.
• ☐ Nearby nuisances: landfill, highway, quarry, shooting range.
• ☐ People living on the land or using it without permission.

For commercial or previously industrial land, consider a Phase I Environmental Site Assessment.

10. Seller identity and fraud prevention

Vacant land with no mortgage is a common target for seller impersonation fraud.

• ☐ Contact the owner at the mailing address in county records and confirm they're the person you're dealing with.
• ☐ Be cautious when a "seller" wants speed, avoids video calls, or insists on their own notary.
• ☐ Use a title company with strong identity verification; let it choose and verify the notary.
• ☐ Never send funds outside the title company's verified process.

A worked example: why the checklist matters

A 10-acre parcel lists for $18,000, while similar parcels sold for $40,000–$50,000. During due diligence you find:

• No public road frontage and no recorded easement (landlocked).
• About 40% mapped wetlands.
• County requires 300 feet of road frontage for a building permit.

Without legal access and buildability, demand is limited mostly to neighbors and some recreational buyers. A realistic value might be a small fraction of the comps. The "bargain" was priced right, or even high.

Now a second parcel: 5 acres for $22,000, with county road frontage, power at the road, no wetlands, soils rated suitable for septic, and zoning that allows homes. Comparable buildable 5-acre parcels sold for $32,000–$38,000. This one survives the checklist and has room for profit.

Keep a due diligence summary

Record each finding with its source and date:

This summary protects you when you buy and becomes the backbone of your listing when you sell.

How long due diligence takes

For a simple rural parcel with good county websites, the desk research above can take a few hours, and the title commitment usually arrives within one to two weeks of ordering. Utility estimates, septic questions, and HOA estoppel letters can take longer. That's why land purchase agreements commonly include a due diligence period of 30–60 days. Ask for enough time in your contract, start the research the day the contract is signed, and keep the seller informed about what you're checking and why. If something fails the checklist, tell the seller promptly and either renegotiate based on what you found or cancel within your contingency period.
