Title, survey and access

Boundary Survey vs. ALTA Survey for Land Buyers

Both survey types can clarify land geometry, but they are ordered for different scopes and transaction needs.

Direct answer

A boundary survey focuses on the parcel boundary and improvements within its scope; an ALTA/NSPS survey adds a nationally standardized title-oriented framework and selected Table A items for more complex transactions.

This is a US-wide research framework. The controlling rule, record, professional standard and approval process can change by state, county, city and project.

What this due-diligence check covers

A boundary survey focuses on locating property lines and corners under state standards. An ALTA/NSPS survey is commonly used in commercial and title-driven transactions with a nationally standardized set of items.

The correct scope depends on lender, title insurer, project complexity, acreage, improvements and the specific risks already discovered.

Why it matters before closing

A survey can reveal overlaps, gaps, encroachments, access locations and easements that a county GIS parcel layer cannot establish.

Three levels of evidence

Evidence level

First question to resolve

Ask the title company and lender what survey standard they require.

Evidence level

Proof to keep

Preserve signed survey and certification and connect it to the exact parcel, proposed use and source date.

Evidence level

Escalation trigger

A survey ordered without the current legal description. Ask: What survey standard does the lender require?

What to verify

  • Ask the title company and lender what survey standard they require.
  • Provide the title commitment and recorded exceptions to the surveyor.
  • Specify desired optional items before the quote is accepted.
  • Confirm whether access, improvements, utilities and flood information are included.

Red flags that deserve follow-up

  • A survey ordered without the current legal description.
  • No title documents supplied to the surveyor.
  • Pins found in the field but no professional opinion on the boundary.
  • Acreage that differs materially from the contract or listing.

Evidence to keep in the parcel file

  • Signed survey and certification
  • Field notes or corner information
  • Title commitment supplied to surveyor
  • Resolved discrepancy record

Questions to ask before the deadline

  1. What survey standard does the lender require?
  2. Will the survey plot recorded easements?
  3. Does the survey show legal and physical access?
  4. Are improvements or fences encroaching?
  5. Who receives and may rely on the certification?

What this evidence does not prove

Public records and online tools can identify risk, but they do not replace the controlling document, written agency decision, title review, survey, engineering or environmental work required for the actual parcel and project.

Frequently asked

Questions land buyers ask

Is a county parcel map a survey?

No. It is an administrative mapping tool and may be generalized or shifted.

Do all land purchases need an ALTA survey?

No. Many residential or rural transactions use a boundary survey, but complex, financed or commercial deals may justify an ALTA/NSPS scope.

Can a survey guarantee buildability?

No. It provides boundary and selected site information; zoning, septic, environmental and engineering questions remain separate.
