Do I need a land survey before buying land?
Sometimes the survey is the only answer. More often it is an expensive way to ask a question the records already answered.
No law requires a survey to buy land. A deed can transfer with a legal description written in 1912 and nobody will stop the closing. The real question is narrower: does anything about this parcel turn on exactly where the lines are, and if so, is the record already good enough to answer it?
Order a survey when
- A lender or title underwriter requires one to close, or the title commitment excepts survey matters you need insured.
- A fence, driveway, shed or field appears to cross a line — encroachments become your problem the day you close.
- The parcel was split off and never separately surveyed, so its description was written by subtraction.
- The deed calls describe trees, stones, creeks or fence posts instead of measured bearings and distances.
- You are buying by the acre at a price where a 5% acreage error matters, or you plan to split or subdivide.
- A neighbor, a hunting lease or an adverse-possession story is already in the picture.
You can usually wait when
- The parcel is a lot on a recorded subdivision plat with monuments still set.
- A survey from the last 20 years exists — check the county and ask the seller before you pay for a new one.
- The open questions are access, zoning, flood, wetlands, septic or taxes. A survey answers none of those.
A survey measures the parcel. It does not tell you whether you are allowed to use it.
The cheaper first step
Before spending two to six thousand dollars on fieldwork, spend a fraction of it reading the record: the deed chain and every recorded easement, the zoning and permitted use, FEMA flood layers and mapped wetlands, tax and assessment status, and whether legal access exists on paper. Most deals that fall apart, fall apart on one of those — not on where a corner pin sits.
If the record is clean and the boundary is still the open question, order the survey then. You will have a smaller list of questions for the surveyor, which is also a cheaper survey.
Protect yourself in the contract either way
Write a survey contingency with a real deadline — surveyors are commonly booked three to six weeks out — and state who pays and what happens if the survey shows less acreage or an encroachment. A contingency costs nothing and buys you the right to be wrong.
