When you're buying property or refinancing a mortgage, your lender will likely require a survey—but not all surveys are equal. An ALTA survey and a boundary survey serve different purposes, cost different amounts, and reveal different information about your land.
What Is a Boundary Survey?
A boundary survey (also called a property survey) marks the legal lines of your property using existing deeds, recorded documents, and field measurements. The surveyor locates corner monuments, stakes, or marks that define where your land ends and your neighbor's begins. This is the most straightforward type of survey and the one most residential homebuyers encounter.
Boundary surveys typically cost between $300 and $1,000 depending on property size, terrain, and local market rates. The process usually takes 1–3 weeks from order to final report. It answers one core question: Where exactly is my property line?
What Is an ALTA Survey?
ALTA stands for American Land Title Association. An ALTA survey is a specialized, title-insurance-grade survey that goes far beyond boundary lines. It includes boundary information plus extensive detail about improvements, easements, encroachments, right-of-way access, utility locations, and other title-related matters.
ALTA surveys follow strict national standards (ALTA/NSPS standards) and are required by most commercial lenders, investors, and title companies. They're especially common in commercial real estate transactions, subdivision work, and complex properties.
Expect to pay $1,500–$5,000+ for an ALTA survey, with larger or more complicated properties running higher. Timeline typically stretches to 4–8 weeks because the surveyor must research title history, contact utility companies, and verify numerous legal encumbrances.
Key Differences at a Glance
| Feature | Boundary Survey | ALTA Survey | |---|---|---| | Primary Purpose | Locate property lines | Title insurance & complex transactions | | Scope | Boundary lines only | Boundaries + easements, encroachments, utilities | | Standards | Local/state practices | ALTA/NSPS national standards | | Cost | $300–$1,000 | $1,500–$5,000+ | | Timeline | 1–3 weeks | 4–8 weeks | | Best For | Residential home purchase, fence disputes | Commercial deals, refinance, investment |
When You Need Each Type
Choose a boundary survey if:
- You're buying a residential home and your lender accepts it (ask first)
- You have a fence-line dispute with a neighbor
- You want a quick, affordable baseline of property lines
- You're building a deck or addition and need to confirm setback distances
Choose an ALTA survey if:
- Your commercial lender or title company requires it (most do for loans over $500K)
- You're refinancing a commercial property
- You're subdividing land or developing a site
- You're purchasing investment property with complex title issues
- You need documented proof of utility easements or right-of-way access
What to Look for When Hiring a Surveyor
Don't just pick the cheapest option. Verify that your surveyor holds a Professional Land Surveyor (PLS) license in your state—this is non-negotiable. Ask whether they specialize in residential or commercial work; a surveyor experienced in your transaction type will deliver more relevant results.
Request references from recent clients similar to yours. Ask upfront whether the surveyor holds errors and omissions insurance and how long they retain records (important if title issues arise later). Get a written scope of work and timeline before signing, and clarify what's included in the fee—some surveyors charge extra for revisions or title research.
If you're unsure which survey type your lender needs, ask them directly in writing. Many residential lenders are flexible, but commercial and refinance lenders typically mandate ALTA standards.

Frequently Asked Questions
Q: Will my home insurance cover survey costs if a boundary dispute arises? No—title and homeowners insurance typically don't cover boundary disputes or survey costs. This is why accurate boundary documentation at purchase is critical.
Q: Can I use an older survey from a previous property transaction? Not reliably. Surveys expire in terms of usefulness; lenders usually want a recent survey (within 6–12 months) because property conditions, utility lines, and legal encumbrances change.
Q: How long does a surveyor keep their field notes and records? Most states require PLS licensees to retain records for 5–10 years; ask your surveyor their retention policy when you hire them, as this affects future reference if you resell.
