A property deal doesn’t care which survey you’d prefer. It cares about what your lender, title company, and attorney need to close. That’s the real question behind “ALTA or boundary survey.” Get it wrong and you either pay for more than the deal calls for, or you show up short at the closing table.
The Deal Determines the Survey Standard
The type of survey a deal calls for isn’t set by acreage or how big the property is. It’s set by the transaction itself: what the property will be used for, what the lender wants, and what the title company will accept.
Louisiana surveyors work under two separate sets of rules. The state has its own Standards of Practice for Boundary Surveys, found in Louisiana Administrative Code Title 46, Part LXI, Chapter 29. These rules come from the Louisiana Professional Engineering and Land Surveying Board (LAPELS) and cover how a licensed surveyor locates and marks property lines. Louisiana’s licensure law, La. R.S. 37:681-703, backs these rules for any survey or map meant to define property corners in the state.
ALTA/NSPS is a different animal. It’s a national standard, jointly published by the American Land Title Association and the National Society of Professional Surveyors. It sets minimum requirements for a survey used to remove the general survey exception from a title insurance policy.
An ALTA/NSPS survey isn’t automatically required just because a deal is commercial. Plenty of commercial purchases and refinances, even large ones, close on a boundary survey alone. The lender and title company decide what they need. The surveyor follows their lead once that’s clear.
When the Title Team Needs More Than a Boundary Line
Some deals need more than a line on a plat. They need a survey that speaks directly to the title.
That’s where ALTA/NSPS comes in. The standard was built for one job: giving a title insurer enough detail to drop the general survey exception from a policy. To do that job, the surveyor has to work from the title commitment, not just deed records. Section 6 of the 2021 ALTA/NSPS standard covers how easements, encumbrances, and other matters listed on the title commitment get noted and shown on the plat.
This turns a commercial deal into a coordination job. The buyer orders the survey. The lender sets its requirements. The title company hands over its commitment and any prior surveys. The attorney checks the plat against the title work. The surveyor ties all of it together on paper.
None of that happens without the title commitment landing on the surveyor’s desk early. A surveyor working without the list of title exceptions can’t do the job an ALTA/NSPS survey is meant to do.
Louisiana adds its own layer on top. A licensed surveyor performing an ALTA/NSPS survey in this state still has to follow Louisiana’s own boundary-survey rules for how corners get located and marked. The national standard sits on top of the state one. Both apply at the same time.
Where a Boundary Survey May Be the Better Fit
Not every deal needs a title-grade survey. Some just need to know where the property line sits.
A straightforward purchase, a refinance with no title exception at stake, or a deal where the lender has no ALTA requirement can often move forward on a boundary survey alone. The question being answered isn’t what the title company needs to see. It’s simply where the parcel begins and ends.
A boundary survey still has to meet the state’s Standards of Practice for Boundary Surveys under LAC Title 46, Part LXI, Chapter 29. The surveyor follows the classification and accuracy rules set out there, based on how the property is used and what’s planned for it. That’s a real, regulated survey with its own required detail.
The difference comes down to purpose. A boundary survey answers a location question. An ALTA/NSPS survey answers a title question. If your deal only has a location question, there’s no reason to pay for the title answer.
The Scope Can Change the Answer
Two people can ask for “an ALTA survey” and mean two different things.
The scope of an ALTA/NSPS survey isn’t fixed. Beyond its required sections, the standard includes Table A, a list of optional items the client can request: zoning notes, flood zone data, utility locations, and more. Each item gets negotiated between the client and surveyor before the work starts. Skip that conversation and you might get a survey that technically meets the ALTA/NSPS minimum but misses something your lender actually wanted on the plat.
The written scope of work matters more than the label on the order form. So does the title commitment, any lender instructions, and the specific Table A items chosen. A surveyor can’t guess what a lender wants shown. Someone on the deal has to write it down.
Before ordering anything, ask what the transaction team actually needs the survey to show. Don’t assume that ordering “an ALTA” checks every box a specific deal needs. It only checks the boxes someone asked for.
A Deal-by-Deal Decision
Here’s a working way to sort it out:
- Commercial purchase with a lender or title requirement. Confirm in writing whether an ALTA/NSPS survey is required before ordering anything.
- Deal centered on where the property line sits. Talk to a licensed surveyor about a boundary survey under the state’s Standards of Practice.
- Redevelopment or a specialized use. Find out what additional survey details the project needs before fieldwork starts.
- Unclear lender or title instructions. Get the requirements in writing first. Don’t order a survey to find out what was needed.
The most useful step in any deal is the one before the survey starts. Ask the title company, the lender, the attorney, and a licensed surveyor what standard and scope this specific deal calls for. That conversation costs nothing and saves a second survey later.
