What Todd Surveys Are and Why Property Owners Need Them

A Todd survey shows the exact boundaries of your property and what structures sit on it

A Todd survey is a legal document that maps the precise boundaries of a piece of land and identifies all buildings, fences, driveways, and other structures within those boundaries. The surveyor uses specialized equipment to measure distances and angles, then produces a drawing to scale that shows where your property line actually sits—not where you think it sits or where a neighbor believes it is.

In South Carolina, a Todd survey serves as the official record of what belongs to your property and what does not. It becomes essential when you are buying or selling land, building a fence or addition, resolving a boundary dispute with a neighbor, or refinancing a mortgage. Lenders often require one before they will fund a loan, because the survey protects them by confirming the property they are lending against actually exists as described.

The name comes from the legal principle that a survey must show all improvements "to the Todd line"—meaning everything that sits on or crosses the property boundary gets documented. This prevents disputes later when a neighbor claims a fence was always theirs, or when a building inspector questions whether an addition was built on the correct lot.

Key Takeaways

• A Todd survey maps your exact property boundaries and shows every structure on the land, creating a legal record of what belongs to your property.
• South Carolina lenders typically require a Todd survey before approving a mortgage or refinance, and title companies often will not close without one.
• The survey costs between several hundred and several thousand dollars depending on property size, terrain, and how old the previous survey is.
• A licensed South Carolina surveyor must perform the work; the state requires specific credentials and insurance to practice land surveying.
• The process usually takes one to three weeks from the time you hire the surveyor until you receive the finished document.

When you need a Todd survey in South Carolina

Real estate transactions are the most common reason. If you are buying property, your lender will almost certainly require a current survey before closing. If you are selling, providing a recent survey to buyers speeds up their financing process and reduces the chance a deal falls apart over boundary questions. South Carolina title companies typically will not issue a title insurance policy without a survey on file, especially for properties that have not been surveyed in many years.

Construction and property improvements trigger the need as well. Before you build a fence, deck, pool, or addition, a survey confirms you are not building on your neighbor's land or violating setback requirements that local zoning codes impose. If a code enforcement officer questions whether your structure is legally placed, a survey becomes your proof. The same applies if you are subdividing land to sell off a portion—the surveyor must create a new legal description for each piece.

Boundary disputes with neighbors are another driver. If a neighbor's fence, driveway, or building appears to cross into your property, a Todd survey provides the legal documentation needed to resolve it. Some disputes settle once both parties see the actual boundary on paper; others require the survey as evidence in a property line lawsuit.

What a Todd survey includes and how it is created

The finished survey document shows your property as a scaled drawing with the boundary lines clearly marked, distances labeled in feet, and the location of every structure noted—house, garage, shed, fence, driveway, pool, or anything else that sits on the land. The surveyor also marks easements (rights others have to use part of your property, like utility lines) and any encroachments (structures that cross the boundary). The document includes the property's legal description, the surveyor's license number and seal, and the date of the survey.

To create it, the surveyor begins by researching the property's deed and any previous surveys on file at the county register of deeds. They then visit the site with equipment that measures distances and angles with precision—traditionally a transit and measuring tape, though many modern surveyors use GPS and laser technology. They locate the original property corners (often marked by iron pins or stones set decades ago) and measure from there to establish where the boundary actually runs. They photograph structures, note their distance from the boundary, and record any visible encroachments.

Back in the office, the surveyor draws the survey to scale using the measurements collected in the field. They cross-check their work against the legal description in the deed to make sure everything matches. Once complete, they sign and seal the document with their professional stamp—that seal is what makes it a legal record that courts and lenders will accept.

Cost and timeline for a Todd survey in South Carolina

Price varies widely based on property size, terrain difficulty, and how recent the previous survey is. A straightforward residential lot in a developed area might cost $400 to $800. A larger property, land with difficult terrain, or a property that has not been surveyed in decades can run $1,500 to $3,000 or more. Some surveyors charge by the hour; others quote a flat fee for the job. Always get a written estimate before work begins.

The timeline typically runs one to three weeks from the date you hire the surveyor until you receive the finished document. The surveyor needs time to research records at the county register of deeds, schedule a site visit, conduct the fieldwork, and then draft and review the final drawing. If the property is remote, weather delays fieldwork, or the surveyor is backlogged, it may take longer. If you are on a tight closing deadline, tell the surveyor upfront so they can prioritize your job.

Finding a licensed surveyor in South Carolina

South Carolina requires land surveyors to hold a Professional Land Surveyor (PLS) license issued by the South Carolina Board of Registration for Professional Engineers and Surveyors. You can verify a surveyor's license on the board's website before hiring them. The license confirms they have met education and experience requirements and carry the liability insurance needed to protect you if their work is wrong.

Your real estate agent, lender, or title company can recommend surveyors they work with regularly. Local county assessor offices and the South Carolina Society of Professional Surveyors also maintain lists of licensed practitioners. Get quotes from at least two surveyors before deciding; price and timeline can differ significantly, and a cheaper quote is not always the best value if it means a longer wait or less thorough work.

How a Todd survey protects you in a real estate transaction

When you buy property, the survey confirms that the land you are paying for actually matches the legal description in the deed. It shows whether the house, garage, or other structures sit entirely on your property or whether any part crosses the line into a neighbor's land. If an encroachment exists, you know about it before closing and can negotiate with the seller or decide not to buy.

For lenders, the survey is proof that the collateral they are lending against is real and sits where the deed says it does. Title insurance companies use the survey to identify risks—an encroachment, an easement, or a structure that violates zoning—that they need to note in the policy or exclude from coverage. Without a survey, a lender might discover after closing that the property is smaller than expected or that a neighbor's building sits partially on it, creating a legal mess that is expensive to untangle.

Common issues a Todd survey can reveal

Encroachments are the most frequent discovery. A neighbor's fence, deck, or shed may sit partly on your property, or your structure may cross into theirs. The survey documents this in writing, which gives you options: you can ask the neighbor to move it, negotiate a boundary line agreement, or accept it as is if it has been there for a long time and both parties agree.

Easements often surprise property owners. Utility companies have the right to access underground lines or maintain above-ground poles on your land, even though you own the property. The survey shows where these easements run, which matters if you plan to build something in that area. Drainage easements, access easements for neighboring properties, and public utility easements all show up on a Todd survey.

Setback violations occur when a structure sits closer to the property line than local zoning code allows. A survey reveals this before you buy, so you know whether the house or garage is legally placed. If it is not, you may face a code enforcement order to move or remove the structure, or you may need to seek a variance from the local zoning board.

Frequently Asked Questions

How long does a Todd survey stay valid?

There is no expiration date on a survey itself, but lenders and title companies often want one no older than a few years. If your property has not changed—no new structures, no boundary disputes—a 10-year-old survey may still be acceptable. If you have made improvements or if the lender requires a current one, you will need a new survey. Ask your lender or title company what they will accept.

Can I use an old survey from when I bought the property?

Sometimes, if it is recent enough and the property has not changed. However, if you are refinancing or selling, the new lender or buyer's lender will likely require a current survey. Boundary markers can shift, structures can be added, and lenders want current documentation. Check with your lender before assuming an old survey will work.

What if the survey shows my neighbor's fence is on my property?

You have several options. You can ask your neighbor to move it; many neighbors will cooperate once they see the survey. You can negotiate a boundary line agreement, which is a legal document both parties sign acknowledging the fence location and agreeing to leave it as is. You can also pursue legal action, though that is expensive and usually a last resort. Some encroachments that have existed for many years may be protected by adverse possession law, so consult a real estate attorney about your specific situation.

Do I need a Todd survey if I am just refinancing my house?

Your lender will tell you. Many lenders require a current survey for a refinance, especially if the property has not been surveyed recently or if you have added structures since the last survey. Some lenders will accept an old survey if nothing has changed. Ask your lender upfront what they require so you can budget for it and plan your timeline.

What is the difference between a Todd survey and a boundary survey?

In South Carolina, the terms are often used interchangeably. A Todd survey is a specific type of boundary survey that shows all improvements to the property line. A boundary survey focuses on the property lines themselves. For most purposes—buying, selling, or building—you want a Todd survey because it shows both the boundary and everything on the property.
