To get a boundary survey, you gather your property deed and any prior survey or title documents, hire a licensed land surveyor, and let them research public records, measure your land, and deliver a signed plat showing your exact property lines. A residential boundary survey usually costs between $400 and $5,500 and takes anywhere from a few days to several weeks, depending on the size of your lot, the terrain, and how clean the records are.
Decide Which Type of Survey You Need
Before calling anyone, know what you’re ordering. A standard boundary survey identifies your property corners and boundary lines and is what most homeowners need for a fence, a neighbor question, or a straightforward home purchase. It follows state and local standards, which vary by jurisdiction.
An ALTA/NSPS land title survey is a more detailed product built for commercial transactions, lenders, and title companies. It follows uniform national standards published by the American Land Title Association and the National Society of Professional Surveyors, and it maps improvements, easements, rights-of-way, utility locations, and other elements affecting ownership in addition to the boundary.1National Society of Professional Surveyors. Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys It also costs significantly more.
If a lender or title company is asking for the survey, ask them specifically which one they need. Ordering the wrong type can mean paying for a second survey later.
Gather Your Documents First
The single most important document is your property deed. Its legal description, usually written in metes-and-bounds measurements or by reference to a recorded subdivision plat with lot and block numbers, is the surveyor’s starting point.2Legal Information Institute. Wex Definition of Deed
A copy of any previous survey helps too, because old plats show where monuments were set and how the boundary was originally measured. If you have a title insurance commitment or title report from when you bought the property, pull that as well; it lists recorded easements and encumbrances the surveyor has to account for.
Walk your property before the surveyor arrives and note anything relevant: iron pins or concrete markers you’ve seen, fences that may not follow the line you expect, and any spot where a neighbor’s structure looks close to or over the boundary. Context you give upfront saves the surveyor time, and their time is what you’re paying for.
Hire a Licensed Surveyor
Every state licenses land surveyors, and licensure requires exams administered through the National Council of Examiners for Engineering and Surveying along with any state-specific requirements.3NCEES. Licensure Your state’s licensing board keeps a searchable directory of active licensees, and the National Society of Professional Surveyors maintains one too.
When you call for quotes, tell each surveyor exactly why you need the survey. “I’m building a fence on my back line” is a different scope than “my lender wants an ALTA survey before closing.” Ask about:
- Timeline: when they can start and when you’ll have the final plat.
- Deliverables: whether you’ll receive a recorded plat, a digital file, or both.
- Cost: whether the quote is a flat fee or hourly, and what could push it higher.
- Experience with similar properties in your area.
Get two or three quotes. Pricing varies widely, and the cheapest option isn’t automatically the right one if the surveyor lacks experience with your property type or can’t meet your deadline.
What the Surveyor Actually Does
Records Research
The work starts at a desk. The surveyor pulls public records from the county recorder’s office: your deed, deeds of adjoining properties, prior surveys, subdivision plats, and any recorded easements. For metes-and-bounds properties or a tangled chain of title, this stage can take longer than the fieldwork. Older parcels with missing monuments or thin records require the most digging.
Fieldwork
Next the surveyor comes to the property to locate existing monuments and take measurements with GPS receivers, total stations, and other precision instruments. They look for iron rods, iron pipes, concrete monuments, and cut crosses in concrete. When they set or reset a corner, they typically install a new iron rod or pipe with a stamped cap showing the surveyor’s name and license number. Terrain and local rules dictate the marker type.
Analysis and Final Plat
Back at the office, the surveyor processes the field data, performs mathematical closures on the boundary, and reconciles any conflicts between the record description and what was found on the ground. The end product is a scaled map showing the determined boundary lines, every monument found or set, and the features that matter to your ownership.
Reading Your Plat
A survey plat looks dense at first, but the pieces are consistent. Boundary lines are labeled with their bearings (compass directions) and distances. Every monument found or placed is marked. Easements, rights-of-way, and encroachments show on the drawing, and those are often the details that matter most in daily life. An easement might be a utility strip along your back fence; an encroachment is a physical intrusion like a neighbor’s garage extending two feet past the line.
Standard elements round out the sheet: a north arrow, a graphic scale, a legend, the parcel’s dimensions and acreage, and the surveyor’s signature, seal, and date. Those authenticate the document for recording, title insurance, and court use.
Costs and Timeline
Residential boundary surveys generally run $400 to $5,500, with most standard lots landing in the middle. The spread comes down to a few things:
- Property size. A quarter-acre suburban lot is far less work than a 20-acre rural parcel.
- Terrain and vegetation. Woods, steep ground, or wetlands slow fieldwork and may need specialized gear.
- Type of legal description. Recorded subdivision lots are cheaper than metes-and-bounds parcels that require tracing historical bearings and distances.
- Property history. Missing monuments, conflicting deeds, or a long ownership chain add research hours.
- Improvements on the ground. More structures, fences, and driveways mean more features to locate.
ALTA/NSPS surveys sit above this range, often by several hundred to several thousand dollars, because of the added detail and stricter standards.
On timeline, a small lot with clean records can be done in one to two weeks from hire to finished plat. Bigger or messier properties can take several weeks or months. Weather, the surveyor’s backlog, and how fast the county returns records all move the schedule. If you have a closing date, say so when you hire.
Who Pays
In a real estate transaction, the party requesting the survey usually pays, which is generally the buyer. It’s negotiable, though. Sellers sometimes order one proactively to smooth the sale, and the cost can be split as part of closing negotiations. Outside a sale, whoever needs the survey pays for it.
If the Survey Reveals a Problem
Surveys sometimes turn up uncomfortable news: a neighbor’s fence three feet onto your side, or your own shed hanging over the line.
Encroachments
Start with a conversation. Most encroachments exist because nobody knew exactly where the line was. Show the neighbor the survey and try to work out a resolution. For minor issues like an overhanging branch or a garden bed, that usually settles it. For a structure, the options are typically granting an easement giving the neighbor legal permission to keep using that strip, selling them the encroached portion and redrawing the line, or asking them to remove the structure. If direct talks fail, bring in a real estate attorney experienced in boundary matters.
Boundary Disputes
A professional survey carries real legal weight. The plat is admissible evidence and represents an expert opinion on where the boundary falls. A neighbor who disagrees can hire their own surveyor, and if two surveys conflict, the question can end up before a judge who weighs the methodology of each.
Adverse Possession
A neighbor who has openly used part of your land for a long enough period may have a legal claim to it through adverse possession. The time period and conditions vary by state. A survey is essential evidence either for defending against such a claim or for making one, so if your plat shows long-standing use across a boundary, talk to an attorney soon; delay can affect your rights.
Recording the Survey
Ask your surveyor whether the plat should be recorded with the county. Requirements vary by jurisdiction. If you subdivided land, recording is almost always mandatory. For a standard boundary survey on an existing lot, it’s often optional but worth doing so the work becomes part of the public record for future owners, surveyors, and title companies. Your surveyor can advise on local rules and file it for you.
Keep in mind that boundaries don’t change with time, but a survey’s practical usefulness does fade. Monuments get disturbed by construction or landscaping, new structures won’t appear on an old plat, and terrain can shift after a flood or landslide. If you’re heading into a transaction, building near a line, or facing a dispute, order a current survey rather than leaning on an old one.
