How to buy land to build a home: a step-by-step guide
By Maria Mandap-Fraguada, REALTOR® · September 2026
Buying land to build a home is one of the most exciting purchases you can make, and one of the most detailed. A beautiful lot is only a good buy if it can support the home you have in mind. These are the steps that answer that question before you commit.
Start with the home you want to build
Before you look at listings, sketch the basics: the size of the house, a garage or workshop, a garden, room for kids or animals. That picture tells you how much usable land you need, which way you want the home to face and what you can afford once building costs are added.
Step 1: Confirm the zoning
Zoning decides what can be built and where. Check the permitted uses, minimum lot size, setbacks, height limits and road frontage with the local zoning office. Ask whether the parcel is an approved building lot or would need a subdivision, variance or other approval first.
Step 2: Find out if the lot is buildable
Without public sewer, a home needs a septic system, and a septic design depends on soil testing, often called a perc test. The results shape where the house, driveway and system can go. Some lots can't support a conventional system at all, which is why this test belongs early in the process.
Step 3: Plan for water
If public water isn't available, you'll need a well. Ask about nearby well depths and plan to test the yield and water quality as part of your due diligence.
Step 4: Check access, utilities and easements
Confirm the lot has legal road access and that a driveway can be permitted. Find out how far electric, gas, internet and other utilities have to run, and whether easements give anyone else rights to cross or use the land.
Step 5: Order a survey and review the title
A survey shows the true boundaries, while a title search reveals liens, deed restrictions or covenants that limit what you can build. Wetlands, flood zones, steep slopes and stream buffers can also shrink the buildable area, so ask for them to be identified.
Step 6: Budget beyond the purchase price
Land often costs more to prepare than buyers expect. Plan for:
- Survey, engineering and soil testing
- Septic, well and utility connections
- Clearing, grading and the driveway
- Permit and approval fees
Step 7: Line up financing
Lenders usually treat land differently from a finished home, and land loans often ask for a larger down payment. If you plan to build soon, ask about construction loans or construction-to-permanent financing that covers both the land and the build.
Step 8: Write an offer that protects you
Make the offer contingent on the checks above: soil and septic testing, survey, title, financing and any approvals you need. Due diligence and approval contingencies give you time to confirm the lot works before you're committed.
Common questions
Can I build on any land I buy? No. Zoning, soils, access and environmental limits decide what can be built, which is why they're checked before closing.
What is a perc test? A soil test that shows how well the ground absorbs water. It's used to design a septic system and confirm a lot can support one.
Raw land or an approved lot? An approved building lot has already cleared key hurdles. Raw land can cost less, but the approvals, time and risk are yours.
The right lot isn't just the one with the view. It's the one that can become your home.
