General information, not legal advice

Do You Need a Property Survey When Buying a Home in Tennessee?

Buyers around Manchester and Coffee County often ask me whether they need a survey. The listing shows a lot size, the county map shows lines and the seller points out where the yard ends, so it can feel like the question is already answered. It usually is not. None of those is a survey, and the difference matters most on rural lots, acreage and older homes where fences and driveways have been in place for years.

This guide explains what a Tennessee property survey is, what the state's survey rules require, how lenders and title insurance treat surveys, and what to look for on the plat. It is general information from the Tennessee Code, the rules of the Tennessee Board of Examiners for Land Surveyors, the Tennessee Comptroller, Fannie Mae, the Consumer Financial Protection Bureau (CFPB) and the Coffee County Register of Deeds. It is not legal advice, and I do not recommend surveyors.

What a property survey is

A boundary survey is a measured map of the land you are buying, prepared by a land surveyor after research and field work. Tennessee law defines the practice of land surveying in TCA 62 18 102 to include measuring and locating lines, angles, elevations and natural and man made features, monumenting property boundaries, platting lands and subdivisions, and preparing the maps, plats, field notes and property descriptions that represent those surveys.

Only a registered surveyor can do this work. Under TCA 62 18 101, it is unlawful to practice or offer to practice land surveying in Tennessee, or to advertise as a land surveyor, unless the person is registered or exempt.

Why the listing acreage and the county map are not a survey

The county parcel map. The Tennessee Comptroller's property viewer says its parcel lines are for property tax assessment purposes only and do not represent legal boundaries. They are a best fit picture built by the county assessor from deed descriptions and surveys, and they are not conclusive evidence of ownership in court. The Comptroller's land use data page says the same thing in plain words: these maps cannot be construed as legal boundaries.

The MLS lot size. The acreage you see on a listing comes from the listing agent, and the MLS records where that number came from. Here is what the Realtracs MLS lot size source field shows for the 862 Coffee County residential sales that closed from October 2025 through September 2026 (same scope and window as my Coffee County housing market report):

• Calculated from plat: 411 sales, 47.7 percent
• Tax record: 278 sales, 32.3 percent
• No source entered: 128 sales, 14.8 percent
• Survey: 34 sales, 3.9 percent
• Owner provided: 8 sales
• Agent calculated: 3 sales

On land the pattern shifts. Of the 202 sales on 1 acre or more, 136, or 67.3 percent, took the acreage from the tax record, 34 (16.8 percent) from a plat and 20 (9.9 percent) from a survey. So on most acreage sales here, the lot size in the listing traces back to the same tax map the state says is not a legal boundary. If the exact acreage matters to you, a survey is how you confirm it. My homes with acreage report shows prices and sales by lot size.

What Tennessee requires on a survey plat

The Board of Examiners for Land Surveyors sets minimum standards in its rules, chapter 0820 03, last amended effective May 7, 2025. For a general property survey, Rule 0820 03 .07 requires the plat to be dated, stamped or sealed and signed by the registered surveyor responsible for it, and to show, among other things:

• A title and a location, with a corner tied by bearing and distance to a subdivision corner, the parent tract, a permanent corner or reference point, or the nearest road intersection
• The county and state, the name of the grantor, grantee or person who ordered the survey, the date and a graphic and numeric scale
• The surveyor's name, registration number, company, address, email and phone
• A certification of the survey category and that it meets or exceeds the accuracy rules
• Easements and rights of way within the property that are obvious and apparent, with the survey completed using the recorded deeds
• Whether each corner monument was found or set, with its material and size

Rule 0820 03 .06 adds that easements shown in recorded documents given to the surveyor must be shown, observable evidence of easements such as roads, drains, water courses and utilities must be located and noted, and the area of a closed survey must be shown in acres or square feet. Lines that were not actually surveyed must be marked that way, and a plat compiled from older surveys must say it does not represent a current survey. Under Rule 0820 03 .06(5), a CAD file, PDF or similar digital copy without the surveyor's digital signature and seal is considered a preliminary or draft document.

Survey categories and accuracy

Rule 0820 03 .05 sets minimum accuracy by category, and the surveyor certifies which category applies:

• Category I, urban and subdivision surveys: closure of at least 1 foot per 10,000 feet of perimeter
• Category II, suburban and subdivision surveys: at least 1 foot per 7,500 feet
• Category III, other property surveys: at least 1 foot per 5,000 feet
• Category IV covers surveys that use satellite positioning (GNSS) equipment, which must meet the same precision standards

For parcels of 1 acre or less, the rule says the allowable error must not exceed one tenth of a foot at any corner. A surveyor can always agree to more accuracy than the minimum.

Corners, pins and marking the lines

Under Rule 0820 03 .07, new metal monuments must be at least one half inch across and concrete monuments at least four inches, both at least 18 inches long unless rock is hit, and new monuments must carry a cap or mark with the surveyor's registration number or company name. If an existing monument is found undisturbed and adequate, the surveyor should not set a new one.

Rule 0820 03 .08 says marking the lines between corners is not a requirement of a general property survey. If you want the lines flagged between the pins, for a fence or just to walk them, ask for it when you order the survey.

Does your lender require a survey?

It depends on the loan and the title company. Fannie Mae's Selling Guide, at B7 2 05, says it will not buy a loan on a property with an unacceptable title impediment, particularly unpaid real estate taxes and survey exceptions. Where surveys are not commonly required, the lender must provide an ALTA 9 endorsement on the title policy, and where neither is customary, the title policy must not have a survey exception.

The same section lists minor impediments Fannie Mae accepts, including:

• Encroachments onto a neighbor's land of one foot or less by eaves, overhangs or driveways, as long as there is at least ten feet between the buildings and that property line
• Encroachments onto a neighbor's land that are only hedges or removable fences
• Differences between the appraisal and the records of possession on the length of property lines of up to 2 percent on the front line and 5 percent on other lines, if they do not interfere with the use of the home
• Minor discrepancies in the description of the area, as long as the lender provides a survey and affirmative title coverage against loss from them

Ask your lender early whether it will require a survey, a survey affidavit or an endorsement, and who orders it. My conventional loans guide covers the rest of the Fannie Mae rules that come up most.

Surveys and your title insurance

A title search looks at the public record. A survey looks at the ground. Problems like a fence in the wrong place, a shed over the line or a driveway that crosses a neighbor's lot may not show up in the records at all. Ask your title agent whether your owner's policy will list an exception for matters a current survey would disclose, and whether a survey would let them remove or narrow it. My title insurance guide explains owner and lender policies and the Tennessee owner policy notice.

Where to find an existing survey or plat

Start with the records that may already exist:

• The seller. Ask for any survey, plat or mortgage inspection from when they bought. My prepare to sell checklist asks sellers to gather it.
• The Coffee County Register of Deeds. The office records subdivision plats and boundary surveys and says it can provide a survey in most cases if one has been recorded. Plats of subdivisions, and plats that divide land into lots of less than 5 acres, must be approved by planning and zoning, and every plat needs the surveyor's original seal and signature to be recorded. Copies of plats are $5.00 per page at the office, and documents recorded since January 17, 1990 can be viewed on TitleSearcher by subscription. The office is at 1341 McArthur Street, Suite 2, in Manchester, (931) 723 5130.
• The deed. Your deed's legal description may refer to a recorded plat by book and page.

An old survey is still useful, but it shows the property as it was on that date. A new fence, addition or driveway since then will not be on it, and only a current survey shows today's conditions.

When a new survey is worth it

Every purchase is different, but buyers I work with often order a survey when:

• The home sits on acreage, or the price depends on the land
• The deed describes the land by metes and bounds instead of a lot in a recorded subdivision
• A fence, shed, driveway or garden sits close to a line, or the neighbor's does
• The seller is dividing a larger tract, which may also need planning and zoning approval
• Access to the home is by a shared drive or easement
• You plan to add a fence, pool, garage or barn
• The property borders a creek, the Duck River or a lake, or part of it may be in a flood zone

For lake and river homes, see my Normandy Lake, Tims Ford Lake and Duck River guides. If you need flood insurance, FEMA says a licensed land surveyor, engineer or architect can complete an Elevation Certificate when none exists; my flood zones guide explains how it can affect your premium.

Ordering a survey and checking the surveyor

• Check the license. Use the Tennessee Department of Commerce and Insurance Verify search and choose the land surveyor board. Tennessee requires a professional land surveyor to pass the national Principles and Practice of Surveying exam and a Tennessee specific exam, and it does not register surveyors by reciprocity.
• Say what you need. Tell the surveyor about the loan, the title company, any fence or building plans and whether you want the lines marked between corners.
• Compare prices and timing. The CFPB says you can shop for the services listed in section C of your Loan Estimate, which can include a survey fee, and your lender must give you a written list of providers. You may be able to use one not on the list if the lender agrees.
• Plan around your deadlines. Order early enough that the survey is back before your inspection or due diligence period ends, so you can still act on what it shows. My contract contingencies guide explains those deadlines.

What to look for when the survey comes back

• Does the acreage match what you were told, and what the listing says?
• Are all corners found or set, and does the plat say which?
• Do the house, garage, outbuildings, fences and driveway sit inside the lines?
• Does anything from a neighbor cross onto the land you are buying?
• Are easements, rights of way and utility lines shown, and do any run under a building?
• Is there a note about lines not surveyed, or a statement that the plat was compiled from other sources?
• Is the flood zone line shown, if the property is near water?

If the survey shows a problem, talk with your title company or a Tennessee real estate attorney before your deadline. Options can include asking the seller to fix it, renegotiating or, if your contract allows, ending the contract.

For sellers

A recent survey can answer a buyer's boundary questions before they come up, especially on land. If you have one, include it with your records when you list. My selling land guide covers plats and dividing a tract.

How I help

I do not do surveys and I cannot tell you where a line legally runs. What I do is ask the seller for any existing survey, point out where the listing acreage came from, help you decide whether a new survey makes sense, build time for it into your offer and keep your lender, title company and surveyor working toward the same closing date.
