An ALTA survey is a detailed boundary and title survey of a commercial property prepared to the ALTA/NSPS Minimum Standard Detail Requirements, a national standard set jointly by the American Land Title Association and the National Society of Professional Surveyors. It maps boundaries, easements, improvements, and encroachments so a title insurer can remove standard survey exceptions.
What Is an ALTA Survey?
An ALTA survey is a professionally certified map that shows a property's exact boundaries, the improvements on it, and every recorded easement, encroachment, and right of way affecting it. It follows the ALTA/NSPS Minimum Standard Detail Requirements, most recently revised effective February 23, 2021, so a lender, buyer, and title insurer nationwide read it the same way.
The survey is built from three inputs: a field measurement of the land and improvements, the recorded legal description, and the title commitment. The surveyor plots each recorded exception from the title commitment onto the map, then certifies the result to the named parties. The certification is what lets a title insurer delete the standard survey exception and issue extended coverage.
Component | What it shows |
Boundary lines | The measured perimeter, tied to the recorded legal description |
Easements | Every recorded easement and right of way plotted by location |
Improvements | Buildings, parking, and site features and their setbacks |
Encroachments | Anything crossing a boundary line, in or out |
Table A items | Optional details the client selects, such as zoning or flood data |
How Table A Items Work
Table A is a menu of optional survey items a client negotiates with the surveyor on top of the required baseline. The 2021 ALTA/NSPS standard lists Table A optional items numbered 1 through 21, covering additions such as monuments, address, flood zone, gross land area, contours, building height, parking counts, utilities, and off-site easements. Each selected item adds scope, cost, and time.
The baseline survey is fixed by the standard. Table A is where the deal-specific detail is added. A lender may require Item 6 zoning classification and Item 11 utilities; a developer may add Item 5 contours and Item 20 professional liability coverage. Because the surveyor prices per selected item, two ALTA surveys of similar properties can differ widely in cost depending on which Table A items the parties request.
Why an ALTA Survey Matters
An ALTA survey matters because it is the document that lets a title insurer delete the standard survey exception, converting an unknown boundary risk into an insured one. Without it, the title policy carves out anything an accurate survey would have shown, leaving the buyer to absorb encroachments, unrecorded easements, or access failures discovered after closing.
The cost is small against what it prevents. For many standard commercial sites the fee commonly runs in the range of $3,000 to $8,000, with complex or large parcels reaching $15,000 or more, per industry cost guides including SurveyALTA. On a multi-million-dollar acquisition that is a fraction of one percent, and it is the difference between insured title and a building whose parking encroaches onto a neighbor with no coverage behind it. The rule holds: an ALTA survey turns boundary uncertainty into a priced, insurable line item.
Example
An ALTA survey earns its fee when it contradicts the assumption that the deal is clean. A buyer is under contract on a 2.5-acre retail parcel and orders an ALTA survey with Table A Items 6 zoning, 11 utilities, and 16 encroachments. The survey returns two findings the title commitment alone did not surface.
Finding | Impact |
Loading dock encroaches 3 ft onto adjoining lot | No recorded easement; neighbor could compel removal |
Utility line crosses rear yard | Unrecorded, blocks planned building expansion |
The buyer uses the survey to price the problem before closing. The parties negotiate a recorded easement for the 3-foot encroachment and reroute the planned expansion around the utility line. Had the buyer skipped the ALTA survey, the title policy's standard survey exception would have excluded both issues, and the buyer would have owned a dock it might be forced to demolish. The roughly $6,000 survey fee protected an eight-figure asset.
Variations and Edge Cases
ALTA surveys vary by the Table A items selected, the property type, and whether an existing survey can be updated rather than redrawn. The variants below show where scope and cost move.
Variant | Treatment |
Baseline ALTA survey | The required standard with no optional Table A items added |
Full Table A survey | Multiple optional items added, raising cost and turnaround |
Survey update or recertification | An older ALTA survey refreshed and recertified to current parties |
Multi-parcel survey | One certified survey covering several contiguous parcels |
Off-site easement survey | Item 19 maps a benefiting easement located off the surveyed parcel |
ALTA Survey vs Boundary Survey
An ALTA survey is often confused with a standard boundary survey, and the two overlap but serve different purposes. A boundary survey establishes where the property lines fall, primarily for the owner. An ALTA survey does that and adds title-driven detail, plotting every recorded easement from the title commitment and certifying the result to lenders and insurers under a national standard.
The boundary survey answers where the lines are; the ALTA survey answers what the title insurer will cover. A boundary survey rarely satisfies a commercial lender or lets an insurer delete the survey exception. An ALTA survey is the version built for a financed commercial transaction, which is why lenders and title companies name it specifically.

Cost depends on property size, complexity, and which Table A optional items the parties select.
