What is an ALTA Survey?
An ALTA/NSPS Land Title Survey is a comprehensive boundary survey that meets nationally recognized standards set by the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS). It's required by most lenders and title insurance companies for commercial real estate transactions.
Quick Facts
- What it is: Boundary survey meeting national ALTA/NSPS standards, certified to the title company and lender.
- What it costs: $3,000–$8,000 for a standard commercial property; $2,500–$15,000+ across the cost spectrum.
- How long it takes: 2–3 weeks standard, 5–7 days rush (additional fee), 3–4 weeks for complex sites.
- Current standard: 2026 ALTA/NSPS Minimum Standard Detail Requirements, effective February 23, 2026.
- Validity: No fixed expiration. Lender recency policies vary (Fannie Mae: 360 days before recording; Freddie Mac: 90 days before Note date; HUD/FHA: 90 days for new surveys).
- Who pays: Buyer pays in most commercial transactions; negotiable in the purchase agreement.
What ALTA Stands For (and the ALTA/ACSM Name Change)
ALTA stands for the American Land Title Association, the national trade group representing the title insurance industry. NSPS is the National Society of Professional Surveyors. The standards governing this type of survey are jointly authored and updated by ALTA and NSPS roughly every five years.
Before 2011, the survey was called an "ALTA/ACSM" Land Title Survey — ACSM stood for the American Congress on Surveying and Mapping, which merged into NSPS. You may still see older deeds, title commitments, lender requirement memos, or surveys referencing "ALTA/ACSM" — the survey type is the same, just rebranded. The 2016 standards were the first published under the ALTA/NSPS name. Searches for "ALTA/ACSM land survey" should be treated as equivalent to today's ALTA/NSPS Land Title Survey.
The full, formal name of the deliverable is an "ALTA/NSPS Land Title Survey". Common shorthand variations include "ALTA survey," "ALTA land survey," "ALTA title survey," "ALTA land title survey," and (in lender memos) "ALTA/NSPS survey." All refer to the same deliverable.
Why ALTA Surveys Exist
Title insurance policies contain a standard "survey exception" that excludes coverage for boundary issues, encroachments, and other matters that would be revealed by an accurate survey. This exception typically reads:
"Any facts, rights, interests or claims which are not shown by the Public Records but which could be ascertained by an inspection of the land or by making inquiry of persons in possession."
When a title company receives an acceptable ALTA survey, they can remove this standard exception and provide broader coverage. This protects lenders and property owners from boundary disputes, encroachment claims, and other survey-related issues that could affect property value or use.

What's Included in an ALTA Survey
Every ALTA/NSPS Land Title Survey must meet the Minimum Standard Detail Requirements, which include:
Boundary Survey
Precise location of all property boundaries based on deed research and field measurements
Improvements
Location of all buildings, structures, and significant improvements on the property
Easements
All recorded easements, rights-of-way, and servitudes that affect the property
Encroachments
Any improvements that cross boundary lines—yours onto neighbors or theirs onto yours
Access
Identification of access points to public roads and rights-of-way
Utilities
Visible utility connections and evidence of underground utilities
Beyond these minimums, lenders specify additional Table A items based on their underwriting requirements.
The ALTA Survey Process
Research Phase
The surveyor researches public records, prior surveys, deeds, and title commitments to understand the property's legal description and history.
Field Work
Surveyors visit the property to locate boundary monuments, measure improvements, and document physical features using GPS and total stations.
Analysis
The surveyor analyzes field evidence against record information to develop an opinion on boundary locations and identify any discrepancies.
Plat Preparation
A detailed survey plat is prepared showing boundaries, improvements, easements, and all required certifications.
Certification
The licensed surveyor certifies the plat to the parties specified (typically lender, title company, buyer, and seller).
ALTA Survey Cost
ALTA survey costs vary based on property size, complexity, location, and required Table A items:
Timeline
Factors that extend timelines: poor weather, difficulty accessing property, complex title issues, missing monuments, or disputes with adjoining owners.

What You Actually Receive
When a surveyor delivers an ALTA/NSPS Land Title Survey, the package typically includes:
- Signed and sealed plat — drawing(s) showing boundaries, improvements, easements, and Table A items, with the licensed surveyor's seal, signature, and date. Sheet size, scale, and wet-ink vs. electronic seal requirements vary by state, lender, and title company — confirm format before fieldwork.
- Certification block — explicit statement that the survey complies with the 2026 ALTA/NSPS Minimum Standard Detail Requirements and lists the parties to whom the survey is certified.
- Table A items — every optional item selected by the lender or buyer depicted on the plat or addressed in survey notes. The new Item 20 encroachment summary table (added in the 2026 standards) groups potential encroachments into five categories.
- Surveyor's notes — explanations of how boundary conflicts were resolved, evidence weighed, and discrepancies between deed and field measurements.
- Legal description — either a copy of the record description from the title commitment, or a new "surveyor's description" if discrepancies required revising it.
- Title commitment exhibit references — every Schedule B-II exception that affects the property location is plotted or annotated on the plat.
- Digital files — most surveyors deliver CAD files (DWG/DXF) and georeferenced PDFs as part of the package, especially for development projects.
What the ALTA Certification Block Contains
Every ALTA/NSPS survey carries a certification block in the form prescribed by Section 7 of the standards. The exact wording is set by ALTA and NSPS — surveyors do not write the certification text from scratch. For the prescribed 2026 wording, see the official ALTA summary or the standards document itself.
Every certification block, regardless of the specific transaction, must contain the following components:
- Named parties — explicit list of the parties to whom the survey is certified (typically buyer, lender, title insurance company, and their successors and assigns). Only the named parties can rely on the survey.
- Standards reference — explicit statement that the survey was made in accordance with the 2026 Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys, jointly established and adopted by ALTA and NSPS.
- Table A items listed — the specific numbered Table A items completed (e.g., "Items 1, 2, 3, 4, 6(a), 6(b), 7(a), 8, 9, 13, 16, 18, 20").
- Fieldwork completion date — the date fieldwork ended, which lenders use as the reference date for recency calculations.
- Plat date and surveyor's signature, printed name, seal, and license number — must appear on the plat itself, not on a separate cover letter.
If a party that needs to rely on the survey is not named in the original certification, the surveyor of record can issue a recertification adding the new party. Lenders and title companies often have preferred certification language and may request specific additional parties; these are negotiated with the surveyor before fieldwork begins.
How Long is an ALTA Survey Valid?
ALTA surveys do not legally "expire" — the certification reflects conditions as of the fieldwork date. However, lenders impose recency requirements that effectively cap how old a survey can be at closing. The values below are pulled from each lender's published guide — always confirm with your specific loan officer:
| Lender / Program | Recency requirement | Source |
|---|---|---|
| Fannie Mae Multifamily | 360 days before recording | Official guide |
| Freddie Mac Multifamily | 90 days before Note date | Official guide |
| SBA 7(a) Loan | Per title company requirements | Official guide |
| HUD/FHA Multifamily | 90 days for new surveys | Official guide |
| CMBS (Commercial Mortgage-Backed Securities) | Typically 180 days | No public guide; varies by lender |
| Conventional Commercial | Varies by lender | No public guide; varies by lender |
When an existing survey is current but predates a material change (new construction, new easements, recent subdivision), most lenders require either a full new survey or an "update" performed by the original surveyor of record. For HUD/FHA specifics, see our HUD ALTA survey validity guide.
Common Issues an ALTA Survey Discovers
A surprising share of ALTA surveys uncover issues that affect title insurability or closing. The most common findings:
Encroachments
Fences, driveways, parking, or building corners that cross boundary lines (yours or a neighbor's). The new 2026 Table A Item 20 standardizes how these get reported.
Boundary Gaps & Overlaps
Adjoining deeds that don't perfectly match, leaving "gore" (gap) or "lap" (overlap) areas of disputed ownership.
Unrecorded Easements
Power lines, water mains, or access drives visible on site but not shown in the title commitment — visible evidence raises potential prescriptive-easement claims.
Setback Violations
Existing structures within zoning setback distances — typically requires a Table A Item 6(b) zoning report to confirm.
Missing Monuments
Property corner markers that have been removed, buried, or destroyed — requires the surveyor to re-establish them using best-evidence methods.
Access Issues
Properties that rely on a private easement, driveway, or "paper street" for access — major title insurance issue if the easement isn't legally recorded.
When the survey discovers a material issue, the typical resolution path is: (1) the surveyor documents the issue on the plat, (2) the title company reviews and either adds a new exception or requires curative action, (3) the parties negotiate (boundary line agreement, encroachment release, easement) to clear title before closing.
How to Choose an ALTA Surveyor
The right surveyor for an ALTA/NSPS Land Title Survey is not always the cheapest local surveyor. Lenders, especially institutional ones, scrutinize the surveyor's qualifications. Key criteria to evaluate:
- Licensed PLS / PS in the state of the property. ALTA surveys must be sealed by a surveyor licensed in the jurisdiction where the property is located. Multi-state portfolios often require coordinating with multiple state-licensed individuals.
- Recent ALTA-specific experience. ALTA work differs meaningfully from residential boundary work — Table A items, title coordination, lender-specific certification language. Ask how many ALTA surveys the firm completed in the past 12 months.
- Lender or agency familiarity. Surveyors who regularly work with your lender's underwriting team typically deliver scope and certification language that matches the loan program — fewer review-cycle revisions. Ask the firm how many surveys they have completed for your lender or loan program.
- 2026 standards readiness. Surveyors should be openly producing 2026- standard work and equipped to deliver the new Item 20 encroachment summary table.
- Errors and omissions (E&O) coverage. Confirm professional liability limits meet your lender's contract requirements. Limits vary by lender and deal size — ask the surveyor for a certificate of insurance and review against the loan documents.
- Delivery format and recertification policy. Ask up front about wet-ink vs. electronic seals (state-specific), CAD file delivery, and whether the firm will recertify their own prior survey for a new transaction and at what fee.

Current Standards: 2026 ALTA/NSPS
The current standards are the "2026 Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys," effective February 23, 2026. These standards are jointly developed by ALTA and NSPS and are updated approximately every 5 years. All surveys contracted on or after February 23, 2026 must comply with the 2026 standards.
Key Changes in the 2026 Standards
Technology-Neutral Fieldwork
Prescriptive "on the ground" language replaced with "practices generally recognized as acceptable by the surveying profession," accommodating drones, LiDAR, and AI tools.
Adjoining Property Deeds
Title insurers no longer required to provide adjoining deeds. Surveyors now obtain these independently — formalizing what most already did in practice.
Utility Search Distances
Clarified: 10-foot search radius applies only to utility poles. All other utility evidence uses a 5-foot radius from the property boundary.
New Table A Item 20
New encroachment summary table with 5 required categories of potential encroachments. Expected to be universally selected by lenders.
Simplified RPP Definition
Relative Positional Precision now defined as a 2D standard deviation at 95% confidence level, making compliance verification more straightforward.
Evidence Standard Harmonized
"Visible evidence" replaced with "evidence observed in the process of conducting fieldwork" — a lower, more consistent standard throughout.
For a complete breakdown, see the official ALTA summary of 2026 changes or our NSPS Standards guide.
Frequently Asked Questions
What is an ALTA survey?
An ALTA survey (ALTA/NSPS Land Title Survey) is a comprehensive boundary survey that meets national standards set by the American Land Title Association and National Society of Professional Surveyors. It shows property boundaries, improvements, easements, and encroachments, and is required by most commercial lenders and title companies.
How much does an ALTA survey cost?
ALTA surveys typically cost between $3,000 and $8,000 for standard commercial properties. Costs vary based on property size, complexity, location, and required Table A items. Simple properties may cost less, while large or complex sites can exceed $15,000.
How long does an ALTA survey take?
Standard ALTA survey turnaround is 2-3 weeks from order to delivery. Rush service is typically available in 5-7 business days for an additional fee. Complex properties or difficult site conditions may require additional time.
Who pays for an ALTA survey?
In most commercial transactions, the buyer pays for the ALTA survey as part of their due diligence costs. However, this is negotiable and may be split or assigned to the seller depending on market conditions and the purchase agreement.
What is the difference between ALTA and NSPS?
ALTA (American Land Title Association) represents the title insurance industry, while NSPS (National Society of Professional Surveyors) represents land surveyors. They jointly develop the ALTA/NSPS standards. The survey is properly called an "ALTA/NSPS Land Title Survey," though "ALTA survey" is common shorthand.
What changed in the 2026 ALTA/NSPS standards?
The 2026 standards introduced technology-neutral fieldwork language (accommodating drones and LiDAR), shifted adjoining property deed research to surveyors, clarified utility search distances (10 feet for poles, 5 feet for other utilities), added a new Table A Item 20 requiring an encroachment summary table, simplified the Relative Positional Precision definition, and harmonized the evidence standard throughout.
When did the 2026 ALTA standards take effect?
The 2026 ALTA/NSPS Minimum Standard Detail Requirements took effect on February 23, 2026. Any contract to perform an ALTA/NSPS Land Title Survey executed on or after that date must follow the 2026 standards. Surveys contracted before February 23, 2026 but completed after may use either the 2021 or 2026 standards by agreement of the parties.
Do I need a new survey under the 2026 standards?
If you already have a valid ALTA survey completed under the 2021 standards, it remains valid for its intended purpose. However, if you are ordering a new survey or an update to an existing survey after February 23, 2026, it must comply with the 2026 standards. Lenders may also require the new Table A Item 20 encroachment summary table, which was not available under the 2021 standards.
What does ALTA stand for in real estate?
ALTA stands for the American Land Title Association, the national trade group representing title insurance companies. The ALTA/NSPS Land Title Survey is a survey type jointly defined by ALTA and the National Society of Professional Surveyors (NSPS) — the standards are widely adopted by lenders and title insurance companies as the minimum acceptable survey for commercial real estate transactions.
What is the difference between a boundary survey and an ALTA survey?
A boundary survey shows the location of property lines and corners. An ALTA/NSPS Land Title Survey is a more comprehensive product that also depicts improvements, easements, encroachments, access points, utilities, and selected Table A items, and includes a certification block accepted by title insurance companies. A boundary survey costs roughly $500–$2,500; an ALTA survey runs $3,000–$8,000 for a standard commercial property. See our full ALTA vs boundary survey comparison.
What is an ALTA/ACSM survey? Is it the same thing?
"ALTA/ACSM Land Title Survey" was the official name of this survey type prior to 2011, when the American Congress on Surveying and Mapping (ACSM) merged into the National Society of Professional Surveyors (NSPS). It is the same survey type, just renamed. The 2016, 2021, and 2026 standards were all published as "ALTA/NSPS." Older title commitments, lender memos, or deeds may still reference "ALTA/ACSM" — treat references to either name as equivalent.
What does an ALTA survey include in the certification?
The certification states that the survey was prepared in accordance with the 2026 ALTA/NSPS Minimum Standard Detail Requirements, lists each Table A item completed, names the parties to whom the survey is certified (buyer, lender, title company, and their successors and assigns), and is signed and sealed by the licensed surveyor of record. The certification is the document title insurance underwriters review to determine whether the standard survey exception can be removed from the policy.
How long is an ALTA survey valid?
ALTA surveys do not formally expire — the certification reflects conditions as of the fieldwork date. Lender recency requirements per published program guides: Fannie Mae multifamily requires the survey within 360 days before recording (recertification permitted); Freddie Mac multifamily requires within 90 days before Note date; HUD/FHA multifamily generally requires within 90 days for new surveys; CMBS typically requires within 180 days; SBA 7(a)/504 defers to title company requirements; conventional commercial varies by individual lender. Always confirm the specific date window with your loan officer.
What is an ALTA "as-built" survey?
The term "as-built" is occasionally used informally to describe an ALTA/NSPS Land Title Survey because it shows existing improvements as they are actually built (not as designed). Strictly speaking, an "as-built survey" in construction terminology is a different deliverable focused on confirming whether construction matches approved drawings. If a lender or title company asks for an "ALTA as-built survey," they typically mean a standard ALTA/NSPS survey with Table A items selected to depict improvements, including Item 17 (utility lines) and Item 19 (offsite easements) when relevant.
Can I use an existing ALTA survey for a new transaction?
Sometimes — the surveyor of record can issue a recertification or update if no material changes have occurred and the lender's recency requirement is met. The recertification produces a new certification block addressed to the new parties. Fees and timing vary by firm; ask the original surveyor up front. If material changes (new construction, new easements, subdivision) have occurred, a new survey or a more substantial update is required.
