A piece of land is only worth what you can legally and practically build on it. In the rural parts of Ulster and Dutchess County, that comes down to a short list of questions every buyer should answer before signing a contract. Most of them cost little to check and a great deal to discover after closing.
Zoning and what you can build
Start with the zoning district and its rules: what uses are allowed, the minimum lot size, road frontage and setbacks. A lot that is smaller than the current minimum may still be buildable as a pre-existing lot, or it may not. Our guide to reading zoning and bulk rules walks through it, and our property package pulls the district and its rules for any Ulster County parcel.
Legal access
- Does the lot front on a public road, and is that frontage at least what the zoning requires?
- If access is by a private road or driveway across a neighbor’s land, is there a recorded right of way or easement, and who maintains it?
- Will the town, county or state issue a driveway permit at a safe location? Sight distance and steep grades can rule out the obvious spot.
Septic and perc tests
Without municipal sewer, you need a septic system designed for the soil. A design professional will dig deep test holes to see soil and groundwater and run percolation tests to see how fast water drains. The system design is then submitted to the county health department for approval. Shallow bedrock, high groundwater or slow-draining clay can make a system expensive or impossible. Make the contract contingent on a satisfactory perc test.
Water
- Without municipal water, you will drill a well. Ask neighbors how deep their wells are and how much water they produce.
- Well and septic need minimum separation distances from each other and from property lines, which can shrink the usable building area on a small lot.
- Test water quality on any existing well before closing.
Wetlands, streams and flood zones
New York’s freshwater wetlands rules changed in 2025, expanding what the state can regulate and, for some wetlands, the protected area around them. Federal rules can also apply. Before you buy, ask the state Department of Environmental Conservation whether any regulated wetland is on or near the lot. Check the FEMA flood map too: building in a flood zone changes design, insurance and lending.
Slopes, rock and clearing
Steep slopes raise the cost of the driveway, the foundation and the septic system, and many towns limit building on them. Ledge rock can mean blasting. Ask how much clearing and grading the town allows before a permit is needed.
Utilities
Find out how far the nearest electric pole is. A long run of new line can cost far more than buyers expect. Ask the same about internet service if you plan to live or work there.
Taxes, title and survey
- Get the current tax bills and check for agricultural or forest exemptions that could trigger rollback taxes when the use changes.
- Order a title search and a survey. Unrecorded encroachments, old rights of way and boundary disputes are common on rural land.
- Check for deed restrictions or conservation easements that limit building or subdivision.
Before you sign
The cleanest land purchases make the contract contingent on the things that decide value: a satisfactory perc test, confirmation of legal access, a survey and, for larger plans, subdivision or site plan approval.
