To get a property line survey, hire a licensed land surveyor who will pull your deed and public records, then measure and mark your legal boundaries on the ground. A standard residential boundary survey runs $800 to $5,500 and usually takes one to two weeks. The finished document carries legal weight with lenders, courts, and permit offices, so the steps below are worth doing in order.
Check Whether a Survey Already Exists
Before you pay for anything, find out if the work has already been done. The county recorder’s or clerk’s office in the county where the property sits often has recorded plats and subdivision maps on file. Your title company may have a copy from a previous transaction. The prior owner is sometimes the fastest route of all. If you received a title policy when you bought the property, the issuing company may still have the survey in its files.
Many counties also offer free online GIS mapping tools where you can search by address or parcel number and see boundary lines overlaid on aerial imagery. These are useful for getting a rough sense of shape and size, but they’re maintained for tax assessment and are typically accurate only to within a few feet. A GIS map is not a legal document and won’t satisfy a lender, a court, or a building department.
An older survey can still help even when it’s not current enough for your transaction. It gives a new surveyor reference points and historical context, which cuts research time and lowers your cost. There’s no universal expiration date, but lenders and title companies often want one completed within the last few years. If the property has changed through construction, grading, natural disasters, or a land sale next door, a fresh survey is the safer move.
Pick the Right Type of Survey
Ordering the wrong type wastes money. Ordering one that’s too limited can leave you exposed. Three types cover most homeowner situations.
Boundary Survey
This is the full-scope survey most people picture. A crew works in the field and office, physically marks property corners with monuments, and determines boundary lines through calculation rather than reading the legal description at face value. Boundary surveys carry very little margin of error and are what you need for building a fence, installing a pool, putting up a shed, or resolving any dispute where the exact line matters. They are also the type required for most building permits.
Mortgage Location Survey
Sometimes called a location drawing, this is a lighter product that shows property lines per the legal description and locates existing improvements relative to those lines. It satisfies many lenders and title companies at closing. The accuracy is significantly lower than a boundary survey because much of the work happens in-office rather than through on-site measurement. If you need to know exactly where to place a new structure, this isn’t enough.
ALTA/NSPS Land Title Survey
This is the most comprehensive and expensive option, jointly developed by the American Land Title Association and the National Society of Professional Surveyors. It’s designed to let title insurance companies remove the general survey exception from a policy, which lenders on commercial transactions almost always demand. The 2026 ALTA/NSPS standards took effect on February 23, 2026, and any survey contracted on or after that date must follow them.1National Society of Professional Surveyors. 2026 ALTA/NSPS Standards
If you’re ordering one, the contract must specifically state that a “2026 ALTA/NSPS Land Title Survey” is required and list any optional Table A items. The client, the party paying, and the surveyor should all be clearly identified in the written agreement, since the entity ordering the survey (often a lender or title company) is frequently not the one writing the check.1National Society of Professional Surveyors. 2026 ALTA/NSPS Standards
Gather Your Documents
Pulling a few key documents together before you contact surveyors saves time and often money, since most surveyors bill for research hours. Have your current deed on hand, which contains the legal description. Include any prior survey you can locate. Recorded easements, rights-of-way, and known encroachments are worth having ready too. These help the surveyor understand what limitations or access rights affect the parcel before setting foot on the property.
If you’re planning construction, bring your site plan or architectural drawings to the first conversation. A surveyor who knows you need setback verification or an elevation certificate can scope the work accurately from the start rather than billing for a second visit later.
Hire a Licensed Land Surveyor
Every state requires land surveyors to hold a professional license. The path runs through two national exams administered by the National Council of Examiners for Engineering and Surveying: the Fundamentals of Surveying exam and the Principles and Practice of Surveying exam.2NCEES. PS Exam States add their own education and experience requirements, so a surveyor licensed in your state has met both national and state qualifications. You can verify a license through your state’s board of professional engineers and land surveyors, which most states make searchable online.
Get proposals from at least two or three licensed surveyors. Each proposal should spell out the type of survey, the deliverables you’ll receive, the estimated timeline, and the total fee. Ask whether the quote is flat-rate or hourly, and whether research time and monument setting are included or billed separately. A surveyor who has worked on nearby properties or similar lots will already know the local deed records, which can speed things up. Confirm that the surveyor carries professional liability insurance before signing anything.
What It Costs
A standard residential boundary survey typically costs between $800 and $5,500. The range is wide because so many variables move the price. Properties under an acre on flat, clear ground with good existing records can come in under $1,500. Larger, wooded, or hilly parcels with complicated deed histories push toward the higher end.
Field crews typically bill $220 to $450 per hour, and office research runs $85 to $160 per hour. Some surveyors quote flat fees for straightforward residential lots. Rush jobs carry a premium, and scheduling during winter in cold climates or peak construction season anywhere can affect both price and availability.
The biggest cost drivers:
- Lot size: More acreage means more measurement, more travel across the site, and more data to reconcile.
- Terrain and vegetation: Dense tree cover, steep slopes, wetlands, or heavy brush slow fieldwork and may require specialized equipment.
- Type of legal description: Platted subdivision lots have clear recorded boundary data. Metes-and-bounds descriptions, common on older or rural properties, require the surveyor to trace bearings, distances, and historical references, which takes more time.
- Availability of prior records: Previous surveys, clear deed chains, and intact monuments shorten research. Missing or conflicting records add hours.
- Number of improvements: Every structure, fence, driveway, and retaining wall on the lot needs to be located and documented.
- Location: Surveys in metropolitan areas tend to cost more than rural ones, partly because of higher labor rates and partly because urban lots more often have complex easement and improvement situations.
What the Surveyor Actually Does
The work splits into two phases. Research comes first. The surveyor pulls deeds, subdivision plats, historical survey maps, and any other recorded documents from the county recorder’s office and other public sources. This builds the legal framework for where your boundaries should be based on the chain of title.
During the field visit, the crew uses GPS receivers, total stations, and other precision instruments to locate existing property markers, monuments, and physical features on the ground. They measure distances and angles to determine where property corners fall, then reconcile what they find physically with what the legal records say. Where old monuments are missing or disturbed, the surveyor sets new ones, typically iron rebar or pipe driven into the ground and capped with a plastic identifier showing the surveyor’s license number.
Fieldwork might take a few hours on a simple residential lot or several days on a large or complicated parcel. After the field crew finishes, the surveyor processes the data, drafts the plat map, and prepares the final document in the office.
Reviewing the Finished Survey
The certified survey document typically includes a plat map and a written legal description. The plat is a scaled drawing showing your property’s boundaries, dimensions, corner locations, and the position of any structures, fences, driveways, or other improvements. It also notes easements, rights-of-way, setback lines, and any encroachments the surveyor discovered.
Read it carefully. Look for improvements that cross boundary lines in either direction, whether yours or a neighbor’s. Check that easements match what you expected from your deed. If the surveyor noted discrepancies between the legal description and what they found on the ground, ask for an explanation in plain terms. The surveyor’s seal and signature certify the document’s accuracy and give it legal standing.
If you need to record the survey, check with your local recorder for filing requirements and fees. Recording is typically required when subdividing land or when the survey will support a property transfer. Filing fees vary by jurisdiction but are generally modest.
If the Survey Reveals an Encroachment
Surveys sometimes turn up surprises: a neighbor’s fence sitting two feet onto your property, your garage partially over the setback line, or a shed straddling the boundary. These don’t resolve themselves.
Start with a direct conversation with the neighbor. Many encroachments are accidental, and a good-faith discussion can lead to practical solutions. If both parties agree to leave the encroachment in place, putting the arrangement in writing as a license or easement agreement protects everyone and prevents future claims. Another option is selling the encroached strip to the neighbor, which requires a new deed and possibly a new survey to reflect the adjusted boundary. Contact your mortgage lender before agreeing to sell any portion of your lot.
If a conversation doesn’t work, the legal options include a quiet title action to establish ownership or an ejectment action to compel removal of the encroaching structure. These are court proceedings that require an attorney and aren’t cheap, so most people treat them as a last resort.
Timing matters because of adverse possession. In every state, a neighbor who openly, exclusively, and continuously occupies part of your land without your permission for a statutory period can eventually claim legal ownership of that strip. The required period varies widely by state, from as few as five years to twenty or more, but the clock runs whether you’re paying attention or not. Encroachments left alone long enough can also harden into prescriptive easements, where a court grants the encroaching party a permanent right to use part of your property even though they don’t own it. A survey that catches the problem early gives you the room to fix it before someone else’s use of your land ripens into a legal claim.
