Survey
Survey
Quick Definition
A property survey is a professional measurement conducted by a licensed land surveyor that establishes the precise legal boundaries of a parcel, locates existing structures relative to those boundaries, identifies easements and rights-of-way, and reveals any encroachments (buildings or improvements that cross property lines). Surveys protect buyers from boundary disputes, confirm they are receiving the land described in the deed, and are often required for title insurance and mortgage lending.
What It Means
Property boundaries exist on paper in deeds and public records, but determining exactly where those boundaries are on the ground requires a licensed professional surveyor with specialized equipment. Without a survey, you may not know whether your fence is on your land, whether your neighbor's shed crosses your property line, or whether an easement runs through the area where you plan to build.
Surveys are especially important for vacant land purchases, properties with unclear histories, rural properties, commercial transactions, and any purchase where the buyer is uncertain about boundary locations.
The 2026 update to the ALTA/NSPS Land Title Survey standards (effective February 23, 2026) has changed how surveys are conducted for commercial transactions. Surveyors must now independently obtain adjoining property deed records, produce structured encroachment summary tables when requested, and may use drones and LiDAR under technology-neutral fieldwork rules. These changes add 3% to 8% to most commercial survey costs but improve transparency and consistency.
Types of Surveys
| Survey Type | Description | When Required/Used |
|---|---|---|
| Boundary survey | Establishes property corners and lines | Most residential purchases |
| ALTA/NSPS survey | Most comprehensive; meets 2026 national standards | Commercial transactions; lenders |
| Topographic survey | Maps elevation changes and natural features | Development; grading planning |
| Mortgage inspection / plot plan | Basic verification of structures; not a true survey | Many residential lenders (less rigorous) |
| Construction survey | Stakes out building location before construction | New development |
| As-built survey | Records completed construction | Final inspection; permits |
| Subdivision plat | Divides larger parcel into multiple lots | New subdivisions |
| Flood zone survey (LOMA/LOMR) | Establishes whether property is in flood zone | FEMA flood insurance disputes |
What a Survey Reveals
| Finding | Significance |
|---|---|
| Property corners and dimensions | Exact size and boundaries; compare to deed description |
| Encroachments | Neighbor's structure on your land; your structure on neighbor's land |
| Easements | Location and width of recorded easements physically shown |
| Rights-of-way | Roads and utilities that burden the property |
| Fence vs. property line | Whether existing fence matches legal boundary |
| Building setback compliance | Whether existing structures comply with zoning setbacks |
| Lot coverage | What percentage of lot is covered by structures |
| Flood zone status | Whether property falls within FEMA flood zone |
The ALTA/NSPS Survey: The 2026 Standard
The American Land Title Association (ALTA) and National Society of Professional Surveyors (NSPS) jointly set the minimum standards for ALTA/NSPS Land Title Surveys. The 2026 standards, effective February 23, 2026, supersede the 2021 version and govern all surveys requested on or after that date.
| Feature | ALTA Survey (2026 Standards) |
|---|---|
| Standards | Meets 2026 ALTA/NSPS Minimum Standard Detail Requirements |
| Contents | Boundaries, improvements, easements, encroachments, zoning, utilities, flood zone |
| Required by | Major commercial lenders and title insurance providers on commercial transactions |
| Cost | $3,000-$8,000 for standard commercial parcel; can exceed $15,000 for large or complex sites |
| Liability | Surveyor certifies accuracy; provides legal liability |
| Table A items | 21 optional items (renumbered in 2026); includes new Item 20: Encroachment Summary Table |
Key Changes in the 2026 ALTA/NSPS Standards
According to Holland & Knight's analysis, the 2026 revisions include:
- New Table A Item 20: Encroachment Summary Table. When selected, surveyors must compile a structured table identifying potential encroachments over boundary lines, into rights-of-way or easements, into setback areas, and third-party use without an easement. This replaces the varied narrative approaches surveyors previously used.
- Adjoining-deed research shifted to surveyor. Previously, title companies supplied adjoining property deeds. Under the 2026 standards, surveyors must independently obtain and review these records, adding 2-4 hours per typical site.
- Technology-neutral fieldwork. Drones, LiDAR, and other modern positioning technologies are explicitly permitted, codifying what most surveyors were already doing.
- Enhanced easement documentation. Surveys must clearly state whether easements are shown, cannot be located, are blanket easements, are illegible, or do not affect the property. Surveyors must notify the title insurer if they discover recorded easements not listed in title materials.
- More detailed monument descriptions. Surveyors must describe the relationship of boundary markers to ground surface (flush, below surface, or protruding).
- Utility search distances clarified. Surveyors must identify utility features on or within five feet of the property, and utility poles within 10 feet.
The net impact on cost is approximately 3% to 8% on most commercial quotes.
Survey Costs (2026)
| Survey Type | Typical Cost |
|---|---|
| Mortgage inspection / plot plan | $100-$300 |
| Boundary survey (residential) | $400-$1,000 |
| Boundary survey (larger/rural) | $1,000-$3,000 |
| ALTA/NSPS (commercial) | $3,000-$8,000 (standard parcel); $15,000+ for large/complex sites |
| Topographic survey | $1,000-$5,000 |
| Subdivision plat | $5,000-$20,000+ |
Five factors drive ALTA survey pricing: property size, location (California and the Northeast tend to be most expensive), title document complexity, Table A items selected, and the 2026 standards' added research requirements.
Encroachments: The Most Common Issue
An encroachment is when a structure or improvement extends across a property boundary:
| Type | Example |
|---|---|
| Neighbor encroaches on you | Neighbor's garage overhangs your property by 2 feet |
| You encroach on neighbor | Your fence is 3 feet onto neighbor's property |
| Public ROW encroachment | Your deck extends into city sidewalk right-of-way |
| HOA encroachment | Improvement extends into common area |
Resolution options: negotiate a boundary line agreement (adjusting the legal line), obtain an easement over the encroaching area, remove the encroachment, or reflect the encroachment in a reduced purchase price. Under the 2026 ALTA standards, selecting Table A Item 20 produces a structured summary table of all encroachments, making it easier for title insurers and parties to assess the situation.
Is a Survey Required at Closing?
Requirements vary by transaction type and state:
| Scenario | Survey Typically Required? |
|---|---|
| Residential purchase (new construction) | Yes, builder provides |
| Residential purchase (existing home) | Varies by state and lender; often not required |
| Commercial purchase | Yes, ALTA survey standard |
| Refinance | Usually not required |
| Vacant land purchase | Strongly recommended; often required |
| Cash purchase | Not legally required, but highly recommended |
Many residential transactions use a mortgage inspection report (plot plan) rather than a true survey. It costs less but provides fewer protections. Always consider ordering a full boundary survey for significant purchases.
ALTA surveys are required by Fannie Mae and Freddie Mac multifamily loans, SBA 7(a) and 504 loans, CMBS loans, HUD/FHA multifamily loans, and most conventional commercial mortgages.
Key Points to Remember
- A survey physically locates property boundaries and structures, protecting against encroachments and disputes.
- The 2026 ALTA/NSPS standards (effective February 23, 2026) introduced Table A Item 20 for encroachment summary tables, shifted adjoining-deed research to surveyors, and formalized drone/LiDAR use.
- ALTA surveys cost $3,000-$8,000 for a standard commercial parcel in 2026, up 3-8% from prior years due to new research requirements.
- Surveys identify encroachments (structures crossing property lines), easement locations, and setback compliance.
- Mortgage inspection reports are cheaper alternatives but provide less protection than full boundary surveys.
- Always order a survey when buying vacant land or any property where boundaries are unclear.
Common Mistakes to Avoid
- Skipping the survey to save money: A $400 boundary survey can prevent a $40,000 legal dispute over an encroachment. The cost of a survey is trivial compared to the cost of a boundary lawsuit.
- Confusing a mortgage inspection with a true survey: A mortgage inspection report (plot plan) is not a survey. It verifies that structures exist on the parcel but does not establish precise boundaries or identify encroachments. Many homebuyers mistakenly believe they received a survey when they only got a plot plan.
- Using an outdated survey: Structures may have been added, easements may have been granted, and survey technology has improved. A survey from 10 years ago may not reflect current conditions. Title insurers may require updates.
- Ignoring easements revealed by the survey: An easement running through your backyard can prevent you from building a pool, shed, or addition. Review the survey carefully before closing, not after.
- Not ordering an ALTA survey for commercial transactions: Most commercial lenders require an ALTA survey. Trying to close without one can delay closing costs and jeopardize the transaction.
Frequently Asked Questions
Q: Can I use the seller's old survey instead of getting a new one?
A: You can review an old survey as a reference, but relying on it has risks. Structures may have changed, easements may have been added, and survey technology has improved. For most residential transactions, the practical risk of using a recent (5-10 year old) survey is low if nothing has changed on the property. For commercial transactions or any transaction where changes have occurred, a current survey is essential. Under the 2026 ALTA/NSPS standards, surveys ordered on or after February 23, 2026 must reference the 2026 Minimum Standard Detail Requirements. Title insurers may require updates to old surveys to provide coverage.
Q: What is a "plat" and how does it relate to a survey?
A: A plat is a map of a subdivided parcel, showing all the individual lots in a subdivision, their dimensions, easements, and common areas. When a developer creates a new subdivision, they prepare a subdivision plat that is recorded with the county. Your property's legal description typically references the plat (e.g., "Lot 15, Block 3, Sunrise Estates Subdivision"). The plat provides the official boundary description for all lots in the subdivision.
Q: What happens if the survey reveals my neighbor's fence is on my property?
A: You have options, but the situation requires careful handling. You can: (1) negotiate a boundary line agreement to adjust the legal boundary to match the fence; (2) grant a license for the fence's current location with no permanent rights; (3) require removal of the encroachment; or (4) accept the situation and let prescriptive easement concerns run their course. The longer the encroachment has existed, the more complex the resolution. An encroachment disclosure is also needed at closing if you later sell the property. Under the 2026 ALTA standards, selecting Table A Item 20 will produce a structured encroachment summary table that documents the issue clearly.
Q: How do the 2026 ALTA/NSPS standards affect my commercial transaction?
A: The 2026 standards add 3% to 8% to most commercial survey costs due to the surveyor's new obligation to independently obtain adjoining property deeds. However, the new Table A Item 20 (Encroachment Summary Table) provides a standardized format for documenting encroachments, reducing the need for title insurers to request survey revisions. The standards also formalize the use of drones and LiDAR, which can improve efficiency. Parties should update their standard Table A item checklists to reflect the renumbered items.
