Updated July 2026 · Educational child page of the Land Survey Services hub
Land surveying combines legal records, field measurements, mathematics and professional judgment to answer questions about land. Sometimes the question is “Where is my property line?” Other times it is “What is the elevation here?”, “Where should the building be staked?” or “What does the lender need for this commercial closing?”

Land survey definition
A land survey is the professional measurement and documentation of land. A licensed Professional Land Surveyor researches recorded evidence, collects field measurements, evaluates how the evidence fits together and produces the map, plat, legal description, certificate or digital model required for the project.
What Does Land Surveying Mean?
Land surveying is the discipline of measuring and mapping land for legal, engineering, construction and planning purposes. The word “survey” is broad because the result changes with the question being asked.
A boundary survey retraces legal property lines. A topographic survey maps elevations and features. An ALTA/NSPS survey documents a commercial property for lenders and title insurers. Construction staking transfers an engineer’s design from a plan onto the ground. All are land surveys, but they do not produce the same deliverable.
The important question is not only “Do I need a survey?”
It is “What decision must the survey support?” The correct answer determines the survey type, fieldwork, research, deliverables, price and schedule.
What Does a Land Surveyor Actually Do?
The instrument on the tripod is only one part of the work. A defensible survey normally combines four phases.
2
Fieldwork
A crew searches for monuments and measures corners, features or elevations with GNSS, total stations and other equipment.
3
Analysis
The licensed surveyor reconciles the measurements with the legal and physical evidence and resolves discrepancies.
4
Deliverable
The map, plat, report, legal description, CAD file or staking data is prepared, reviewed and professionally certified.
The amount of time in each phase varies. A newer subdivision lot with intact corner monuments may be straightforward. A rural parcel described by an old metes-and-bounds deed may require extensive record comparison and field searching.
The Main Types of Land Surveys
“Land survey” is the umbrella. The service cards below route you to the page that owns each commercial intent.
Most common residential survey
Boundary Survey
Retraces legal property corners and lines for fences, additions, sales, encroachments and boundary questions.
Explore boundary surveys → Commercial title and lender surveyALTA / NSPS Land Title Survey
Combines boundary work with title commitments, easements, encroachments and selected Table A items.
Explore ALTA surveys → Architecture and engineering baseTopographic Survey
Maps contours, spot elevations, improvements and site features for grading, drainage and design.
Explore topographic surveys → Large-site surface mappingDrone / UAV Survey
Uses aerial imagery, ground control and survey review for terrain models, orthomosaics and volume calculations.
Explore UAV surveying → Build from the engineered planConstruction Staking
Places buildings, roads, utilities, grades and other designed improvements onto the ground for contractors.
Request construction-staking scope → Document completed constructionAs-Built Survey
Measures what was actually constructed for record drawings, lenders, municipalities and closeout.
Request an as-built quote → Parcel and development changeSubdivision or Lot-Line Work
Creates or adjusts legal parcels through plats, legal descriptions, agency review and county recording.
Explore site and development planning → Flood-zone documentationElevation Certificate
Documents building and site elevations for flood insurance, FEMA review and floodplain transactions.
Discuss a flood-elevation project →The complete Land Survey Services hub also covers easements, legal descriptions, condominium plats, survey review, slope calculations and other specialty work.
When Do You Need a Land Survey?
You generally need a survey when the exact location of a boundary, elevation, improvement or proposed design matters to a permit, lender, title company, court, engineer, architect or contractor.
- Before building a fence near a property line
- Before constructing a garage, addition, shop or ADU
- Before purchasing or financing commercial property
- When a fence, driveway or structure may encroach
- Before splitting land or adjusting a lot line
- Before site, grading, drainage or utility design
- Before staking a building or infrastructure project
- When old deeds or survey maps conflict
- When a lender requests an ALTA/NSPS survey
- When flood insurance requires elevation data
- When completed construction must be documented
- When a court or attorney needs professional evidence
A survey is not required for every property decision. Sometimes a recorded plat or existing survey answers the question. Send the available records to Ludlow Engineering before ordering unnecessary work.
What Do You Receive From a Land Survey?
The deliverable depends on the survey type. A boundary survey map is different from an ALTA survey, a topographic CAD base or a construction-staking field report.
| Survey type | Typical deliverable | Common client |
|---|---|---|
| Boundary | Stamped map showing corners, lines, bearings, distances, acreage and relevant improvements or encroachments | Homeowner, buyer, seller, attorney or building department |
| ALTA / NSPS | Title-grade survey coordinated with the title commitment and selected Table A requirements | Commercial lender, title company, attorney or investor |
| Topographic | Contours, spot elevations, mapped features, benchmark, DWG and stamped PDF | Architect, civil engineer, builder or developer |
| Drone / UAV | Orthomosaic, terrain model, contours, point cloud or volume report with survey control | Developer, contractor, engineer, mine or large-property owner |
| Construction staking | Field stakes, offsets, cut/fill information and staking reports | General contractor, excavation crew or utility contractor |
| As-built | Record map or CAD file showing the measured completed improvements | Municipality, lender, owner, engineer or contractor |
A survey does not automatically include every feature.
Before authorization, confirm the survey limits, visible improvements, utilities, trees, contours, title documents, CAD formats and agency requirements. The proposal should define the finished product.
How Much Does a Land Survey Cost?
There is no single land-survey price because different surveys answer different questions. The same property may require a $1,200 boundary survey, a $3,500 topographic survey or a much larger ALTA and development scope.
| Survey category | Current planning range | Major cost drivers |
|---|---|---|
| Residential boundary | Starts at $1,025; many projects $1,025–$2,500 | Records, lot age, missing monuments, acreage, terrain and dispute complexity |
| ALTA / NSPS | Commonly starts around $3,000 | Parcel size, title exceptions, Table A items, utilities and transaction deadline |
| Topographic | Commonly $1,500–$4,500 for residential/design scopes | Acreage, contour density, vegetation, mapped features and digital formats |
| Drone / UAV | Quoted by acreage, accuracy and deliverable | Airspace, ground control, vegetation, surface processing and point-cloud needs |
| Subdivision or specialty work | Custom proposal | Agency requirements, design coordination, number of lots and recording process |
The Utah land and property survey cost guide owns the full pricing discussion. Use this definition page only to understand why prices differ.
How Long Does a Land Survey Take?
A routine residential boundary survey commonly takes one to three weeks from authorization to final map. ALTA surveys commonly require three to six weeks. The field visit may occupy only part of that schedule; research, calculations, drafting and licensed review often require more time.
Factors that extend the schedule
Old or conflicting deeds, missing corner monuments, heavy vegetation, snow, unsafe access, large acreage, title revisions, neighboring-record research, agency comments and urgent transaction changes can all affect delivery.

Common Land Surveying Myths
GIS maps are useful planning tools, but their parcel graphics can be offset from surveyed monument positions.
Fences may follow convenience, terrain or an old agreement. A surveyor evaluates recorded and physical evidence.
Consumer GPS does not provide the legal research, professional analysis, control or certification required for official use.
The surveyor must evaluate monuments, possession, adjoining records, senior rights and other evidence—not only one description.
Recording requirements depend on the survey type, jurisdiction and state law. Some maps are delivered only to the client.
Those are separate professional services. A survey can coordinate with them but does not replace them.
Why Land Surveyor Licensing Matters
A Professional Land Surveyor is licensed by the state to perform and take responsibility for professional surveying work. Field technicians and CAD staff may collect data and prepare drawings under supervision, but the licensed surveyor evaluates the evidence and certifies the final professional work product.
Licensing matters because boundary decisions affect ownership, lending, construction and public records. A surveyor’s seal identifies the professional responsible for the work and the jurisdiction in which that professional is licensed.
Do not confuse locating with surveying.
A contractor, fence company, realtor, mapping app or excavation locator may help identify approximate features, but only a properly licensed surveyor can provide the professional boundary or survey document required for legal and official use.

Frequently Asked Questions
What is a land survey?
A land survey is the professional process of researching, measuring, mapping and documenting land. A licensed surveyor prepares the specific map, plat, description, certificate, digital model or staking information required for the project.
What is a land surveyor?
A land surveyor is a state-licensed professional who evaluates legal records and field evidence to measure and document land for boundaries, design, construction, title, development and public records.
Is a property survey the same as a land survey?
Property survey is an informal phrase commonly used for residential boundary work. Land survey is the broader term. A boundary survey, ALTA survey and topographic survey are all types of land surveys.
Can I survey my own property?
You can make informal measurements, but they are not a professional survey and generally will not be accepted for permits, lending, title, court or recorded property changes.
How do I find my property lines?
Start with your deed, recorded plat and any prior survey. Existing corner monuments may be present, but an authoritative retracement normally requires a licensed boundary surveyor.
Does a land survey show easements?
A survey may show easements when they are visible, supplied in a title commitment or included in the agreed scope. A basic boundary survey does not automatically include a complete title search.
Does a survey include underground utilities?
Not automatically. Visible utility evidence and utility-locate markings may be mapped. Private locating or subsurface utility engineering may be needed for higher-confidence underground information.
How much does a land survey cost?
Ludlow Engineering boundary surveys start at $1,025, ALTA surveys commonly start around $3,000, and topographic design surveys commonly range from $1,500–$4,500. The written proposal reflects the actual scope.
How long is a survey valid?
The measurements document conditions at the time of the survey, while legal boundaries generally do not expire. Lenders, title companies and agencies may require a new or updated survey because improvements, standards and transaction requirements change.
