A certificate of location in real estate is a report prepared by a licensed land surveyor that shows exactly where the house, garage, fences, driveways, and other permanent improvements sit on a lot in relation to its legal boundaries, recorded easements, and zoning setbacks. Mortgage lenders and title companies routinely require one before closing because it surfaces problems no other document can catch, from a fence that crosses the property line to an addition built two feet inside a required setback. For a buyer, it is the clearest picture available of what the land actually contains and how it complies with the rules that govern it.
What the Report Actually Shows
At the core of the document is a map of the lot’s legal boundaries with every permanent structure plotted against them. The surveyor records the footprint and position of the house, detached garages, sheds, fences, driveways, retaining walls, and other fixed features, and each one is measured against the property lines. Anyone reading the certificate can see how close the house sits to the north boundary or whether a deck extends past a setback.
Beyond the structures, the report identifies easements and rights of way that give others access to parts of the land. Utility companies often hold easements to maintain underground lines or overhead wires across private property. A neighbor may hold a right of way to reach a landlocked parcel. These encumbrances control where you can build and how you can use portions of your lot, and having them mapped before you buy is the only reliable way to know they exist.
The surveyor also checks whether existing structures comply with local zoning. Municipalities set minimum distances between buildings and property lines, limit how much of a lot can be covered by structures, and impose height restrictions. If a previous owner added an addition that sits inside a required setback, the certificate flags that violation. Knowing before closing lets you negotiate a price adjustment, ask the seller to cure the problem, or walk away.
How It Compares to Other Surveys
A certificate of location is one kind of property survey, and the differences matter when a lender or title company specifies what they want.
- A boundary survey establishes the legal corners and lines of a parcel by combining field measurements with deed research. The surveyor locates or sets physical monuments, typically iron pins, at each corner. It is the most common type for residential transactions and boundary disputes.
- A location survey, which is what a certificate of location documents, goes a step further. It maps the boundaries and shows the position of all improvements relative to those boundaries and to setback lines. Most residential mortgage lenders accept this level of detail.
- An ALTA/NSPS land title survey is the most comprehensive standard, governed by requirements jointly set by the American Land Title Association and the National Society of Professional Surveyors. The 2026 edition took effect on February 23, 2026, superseding earlier versions. Commercial lenders almost universally require this type.1National Society of Professional Surveyors (NSPS). 2026 Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys
- A topographic survey captures elevation changes, contours, drainage patterns, and natural features. Engineers and developers use these to plan grading and site design. A topographic survey does not establish legal boundaries on its own.
- An as-built survey is performed after construction to confirm that buildings, roads, and utilities were built according to approved plans. Local building departments sometimes require one before issuing a certificate of occupancy.
If you are buying a home, a location-level survey is usually what the lender and title company have in mind. If the transaction is commercial, the request will almost always be for an ALTA/NSPS survey, and the specific optional items the lender wants will be spelled out in writing.
When You Need One
Several events call for a fresh certificate of location or an update to an existing one. The most common is a property purchase. Lenders generally want a survey recent enough to reflect the current state of the land. Title companies often accept surveys less than five years old, though some require them to be no more than six months old to remove certain title insurance exceptions. If a survey is older but nothing has changed, a surveyor can sometimes update it with a re-inspection and a new certification rather than starting over.
Fannie Mae’s selling guidelines illustrate how this plays out in residential lending. Fannie Mae does not require a survey on every loan, but it does require that title policies either have no survey exception or include an ALTA 9 endorsement in jurisdictions where surveys are not customary.2Fannie Mae. Title Exceptions and Impediments Either way, something has to address the risk that a physical inspection would reveal, and a current survey is the cleanest way to do it.
You will also likely need a new survey if you build an addition, pool, or garage that changes the property’s footprint, since the old survey no longer reflects reality and your building permit application may require an updated one. Some lenders ask for a current survey before approving a refinance, especially if the property has been improved. Splitting one parcel into two or merging adjacent lots creates new legal descriptions that demand fresh boundary work. And when neighbors disagree about where one property ends and another begins, a boundary survey is often the first step toward resolution.
Why It Matters for Title Insurance
A standard title insurance policy includes a survey exception that excludes coverage for anything a physical survey would have revealed. Skip the survey, discover later that your neighbor’s driveway crosses your property line, and the title policy will not cover you.
To remove that exception and get full coverage, title companies typically require a current survey showing all existing improvements. The general rule is that it should be no more than six months old. An older survey may be acceptable if someone familiar with the property provides a sworn affidavit describing any changes since the survey date.
Several title insurance endorsements depend specifically on survey information. The ALTA 25-06 endorsement confirms that the survey depicts the same property described in the title commitment. The ALTA 17 series covers access rights and requires the surveyor to show all access points and curb cuts. The ALTA 28 series addresses encroachments, providing insurance against losses if you are forced to remove a structure that crosses a boundary or easement.3National Society of Professional Surveyors (NSPS). 2021 ALTA/NSPS Standards Without a survey, none of these endorsements are available.
What a Survey Can Reveal and What to Do About It
Surveys exist to surface problems before they become expensive, and they regularly do. The most common discoveries are encroachments, setback violations, and unrecorded easements.
An encroachment occurs when a structure from one property crosses onto another. A neighbor’s fence sitting six inches onto your side of the line is routine. A detached garage sitting three feet over is a bigger deal. Your options depend on the severity and your tolerance for risk:
- Negotiate a boundary line agreement. Both owners sign a recorded agreement recognizing the encroachment and agreeing not to pursue removal.
- Obtain title insurance endorsements. ALTA 28 series endorsements can insure against loss from encroachments if the title company is willing to issue one.
- Demand removal. If the encroachment is significant, require the seller to resolve it before closing, or negotiate a price reduction reflecting the cost of future removal.
- Walk away. If the encroachment is severe enough to affect your intended use of the property, terminate the purchase agreement under your inspection contingency.
Setback violations work differently because they involve the municipality rather than a neighbor. If a prior owner built a deck that encroaches into a required setback, you are inheriting that noncompliance. Some jurisdictions allow grandfathering of pre-existing nonconforming structures. Others may require a variance application. In serious cases a municipality can order the structure removed. The real risk is often forward-looking: even if no one comes after you for the existing violation, the building department may refuse to approve new work until you resolve it.
When a survey uncovers an unrecorded easement or one that was not in the title commitment, the title company needs to know immediately. Surveyors are professionally required to notify the title company of any recorded easement discovered during research that was not listed in the title evidence provided.1National Society of Professional Surveyors (NSPS). 2026 Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys How it affects your transaction depends on whether the easement interferes with your plans. A utility easement along the back ten feet is standard. An access easement cutting through the middle of a buildable area is a deal-changer.
What It Costs and Who Pays
Survey fees depend on property size, terrain, the type of survey, and how much research the surveyor needs to do. A standard residential boundary or location survey for a typical suburban lot generally runs between $800 and $2,500. Properties with unusual shapes, dense vegetation, or unclear deed histories push costs higher. Research fees for complex title chains can add to the bill.
ALTA/NSPS surveys for commercial properties cost substantially more because the standards demand greater detail and each optional item adds scope. Basic commercial surveys for smaller parcels start around $3,000, while complex properties with multiple buildings, extensive easements, or large acreage can exceed $15,000.
In most real estate transactions the buyer pays for the survey as part of closing costs, though this is negotiable. Some purchase agreements split the cost or assign it to the seller. If the seller already has a recent survey, ask your title company whether they will accept it with an update affidavit rather than requiring a new one. That can save hundreds of dollars.
What to Have Ready Before Hiring a Surveyor
Having the right documents ready before your first call keeps the project on schedule. The surveyor will do their own research, but a head start means fewer billable research hours and a faster turnaround.
- Your current deed. The legal description is the surveyor’s starting point and defines the parcel in terms they can translate into physical measurements.
- The title commitment or preliminary title report from your title company. It lists all recorded easements, liens, and encumbrances affecting the property, and without it the surveyor may miss an easement with no visible evidence on the ground.
- Any previous surveys. An older survey helps the surveyor understand historical boundary markers and previously noted encroachments, and can speed up fieldwork if the earlier monuments are still in place.
- Building plans or site plans. If you have done construction or are planning any, these let the surveyor know what to look for and what to measure.
To find a qualified surveyor, check your state’s professional licensing board. Every state maintains a registry of licensed land surveyors, and most offer searchable online databases. When comparing firms, ask whether they carry professional liability insurance and confirm they are familiar with the specific type of survey your lender or title company requires. A surveyor experienced with ALTA/NSPS standards is not interchangeable with one who primarily does construction staking.
One boundary worth knowing: a certificate of location is not a FEMA Elevation Certificate. The location certificate shows where structures sit on the lot. An Elevation Certificate measures how high a building sits relative to expected flood levels and must be completed by a licensed surveyor, engineer, or architect authorized to certify elevation information.4Federal Emergency Management Agency (FEMA).
