ALTA Survey vs Boundary Survey: What's the Difference?
Both ALTA and boundary surveys define property lines, but they serve different purposes. Boundary surveys establish the legal limits of a property and locate corners. ALTA surveys do everything a boundary survey does, plus meet national standards required by title companies and lenders for commercial real estate transactions. The right choice depends on your transaction type and lender requirements.

Pro Tip: When to Upgrade to ALTA
Even for residential properties, an ALTA survey may be worth the extra cost if the property has complex easements, access issues, or you're planning significant improvements. The comprehensive information can prevent costly surprises after closing.

Any commercial real estate transaction with financing requires an ALTA survey. No exceptions from major lenders.
Residential = Boundary (Usually)
Most residential transactions need only a boundary survey, unless complex title issues exist.
ALTA Includes More
ALTA surveys include everything in a boundary survey plus buildings, utilities, easements, and encroachments.
Check With Your Lender
Always confirm survey requirements with your lender before ordering. Some require specific Table A items.
Frequently Asked Questions
What is the main difference between an ALTA survey and a boundary survey?
A boundary survey establishes property lines and corners, while an ALTA survey includes everything in a boundary survey plus detailed information about buildings, easements, encroachments, utilities, and access. ALTA surveys meet national standards required by title companies and commercial lenders, whereas boundary surveys follow only state and local requirements.
Do I need an ALTA survey for a residential property?
Generally, no. Residential properties with conventional mortgages typically only need a boundary survey or location survey. However, an ALTA survey may be beneficial for high-value residential properties, properties with complex easements, or when purchasing land for development. Always check with your lender for specific requirements.
How much more does an ALTA survey cost than a boundary survey?
An ALTA survey typically costs 3-5 times more than a boundary survey. While boundary surveys range from $500 to $2,500 for residential properties, ALTA surveys cost $3,000 to $12,000 or more for commercial properties. The higher cost reflects the comprehensive research, detailed documentation, and additional requirements of the ALTA/NSPS standards.
Why do commercial lenders require ALTA surveys?
Commercial lenders require ALTA surveys because they provide standardized, comprehensive property information that protects both the lender and title insurance company. ALTA surveys identify potential issues like encroachments, easement conflicts, and access problems that could affect property value or create legal liability. The national ALTA/NSPS standards ensure consistent quality across all states.
Can I use an existing boundary survey instead of ordering an ALTA survey?
Not for commercial financing. Lenders and title companies require current ALTA surveys (typically less than 6 months old or recertified) that meet their specific requirements. An existing boundary survey cannot be "upgraded" to an ALTA survey - a new survey must be ordered. However, having a prior survey can reduce costs as the surveyor may use it as reference.
What are Table A items on an ALTA survey?
Table A items are optional additions to the standard ALTA survey that provide specific information requested by lenders or title companies. There are 21 optional items covering things like monuments, setback lines, flood zones, parking counts, and building dimensions. Each lender specifies which Table A items they require, and each item adds $50 to $500 to the survey cost.
How long is an ALTA survey valid?
ALTA surveys are typically valid for 6 months to 1 year, depending on lender requirements. After this period, the survey may need to be recertified by the surveyor (confirming no changes have occurred) or a new survey ordered. Recertification costs $200-$500 and is much less expensive than a new survey, provided no significant changes have been made to the property.
