When buying, selling, or developing commercial property in the United States, one document often becomes critical to the success of the transaction—the ALTA survey. Many property owners hear the term but are unsure what it actually includes, why it is required, or how modern technologies like drone surveys can help meet ALTA standards efficiently.
This guide explains ALTA survey requirements in simple terms, what property owners must know before ordering one, and how advanced surveying methods such as Drone LiDAR Mapping are changing how accurate, fast, and reliable ALTA surveys can be.
Modern survey solutions, including platforms like Skyelink, now support faster data capture and improved coordination for complex land surveys.
What Is an ALTA Survey?
An ALTA survey, officially known as an ALTA/NSPS Land Title Survey, is a detailed property survey prepared according to standards set by the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS).
Unlike a basic boundary survey, an ALTA survey provides comprehensive information about a property, including:
- Legal boundaries
- Easements and rights-of-way
- Access points
- Improvements such as buildings, fences, and utilities
- Encroachments and potential title issues
These surveys are commonly required by title companies, lenders, attorneys, and investors before closing a commercial real estate transaction.
Why ALTA Surveys Are Important for Property Owners
ALTA surveys protect property owners from legal and financial risks. They help ensure that what you believe you are purchasing is exactly what exists on the ground.
Key reasons ALTA surveys matter:
- Avoid boundary disputes with neighbors
- Identify easements that may limit property use
- Meet lender and title insurance requirements
- Support development planning and permitting
- Reduce costly delays during transactions
Without an ALTA survey, property owners may face unexpected restrictions or legal issues after purchase.
Core ALTA Survey Requirements Explained
ALTA surveys follow strict standards that define what must be shown on the final survey. Below are the most important elements property owners should understand.
1. Boundary Lines and Property Corners
Surveyors must clearly define property boundaries based on legal descriptions and physical evidence found on-site. Any discrepancies must be noted.
2. Easements and Rights-of-Way
ALTA surveys identify recorded easements such as:
- Utility access
- Shared driveways
- Drainage or sewer lines
- Public or private rights-of-way
These can affect construction, expansion, or land use.
3. Improvements and Structures
All visible improvements are documented, including:
- Buildings
- Parking areas
- Sidewalks
- Fences
- Retaining walls
Their location relative to property boundaries is critical for identifying encroachments.
4. Access and Adjoining Properties
The survey must show how the property connects to public roads and identify adjacent parcels. This confirms legal access, which is often required by lenders.
5. Zoning and Flood Zone Information
Depending on project needs, ALTA surveys may include:
- Zoning classifications
- Building setback requirements
- Flood zone designations
These optional items are selected using ALTA Table A, which allows clients to customize survey scope.
ALTA Table A Items: What Property Owners Should Know
Table A is a checklist of optional survey features that can be added based on project requirements. Commonly requested Table A items include:
- Utility locations
- Building heights
- Parking counts
- Address confirmation
- Flood zone classification
Selecting the right Table A items ensures the survey meets lender, title, and development needs without unnecessary cost.
How Drone Technology Supports ALTA Survey Accuracy
Traditional ALTA surveys rely heavily on ground-based measurements, which can be time-consuming for large or complex properties. Today, Drone LiDAR Mapping plays an important supporting role in ALTA survey workflows.
Drone-based data collection helps surveyors:
- Capture accurate elevation and surface data
- Map large commercial sites efficiently
- Identify improvements and terrain features
- Reduce time spent in hard-to-access areas
LiDAR-equipped drones can collect high-resolution data even in areas with dense vegetation or uneven terrain, improving overall data quality while supporting licensed surveyors in meeting ALTA standards.
ALTA Survey vs Standard Boundary Survey
Understanding the difference helps property owners avoid ordering the wrong type of survey.
| Aspect | ALTA Survey | Boundary Survey |
| Purpose | Commercial transactions & title insurance | Property line identification |
| Detail Level | Very high | Basic |
| Easements & Improvements | Included | Limited |
| Lender Acceptance | Required | Usually not sufficient |
| Cost | Higher | Lower |
For commercial or high-value properties, a boundary survey alone is rarely enough.
How Long Does an ALTA Survey Take?
The timeline depends on:
- Property size
- Terrain complexity
- Availability of records
- Table A requirements
On average:
- Small commercial sites: 1–2 weeks
- Large or complex sites: 2–4 weeks or more
Drone-supported data collection can significantly reduce field time, especially on large parcels.
ALTA Survey Cost: What Influences Pricing?
While this guide focuses on requirements, cost is a major concern for property owners. Pricing typically depends on:
- Property size and location
- Number of Table A items selected
- Terrain and site complexity
- Existing records and title documents
- Use of advanced mapping technologies
ALTA surveys are an investment in risk reduction and transaction security rather than just a regulatory requirement.
Common Mistakes Property Owners Should Avoid
- Ordering a boundary survey instead of an ALTA survey
- Not reviewing title commitments before survey work begins
- Selecting too few or too many Table A items
- Working with unqualified or inexperienced survey providers
- Ignoring future development plans when defining survey scope
Clear communication with your survey provider prevents delays and unexpected costs.
Conclusion
Understanding ALTA survey requirements helps property owners protect their investment, avoid legal disputes, and move forward with confidence in commercial real estate transactions. These surveys go far beyond basic boundary mapping by providing a detailed, legally recognized picture of a property’s condition, access, and limitations.
With modern solutions like Using Drone LiDAR Mapping and Skyelink , ALTA surveys can now be completed more efficiently while maintaining the high accuracy required by lenders and title companies. By choosing the right survey scope and working with experienced professionals, property owners can ensure compliance, clarity, and peace of mind throughout the transaction process.
