Plat Maps vs. Property Surveys: What’s the difference?While plat maps and property surveys are very similar, they aren’t exactly the same thing. Plat maps show the legal property lines that belong to the owner, but they offer more of a big-picture view of an entire neighborhood or subdivision, whereas a survey is a more in-depth look of a single property. Typically, the title company will order a survey of the property at the request of the buyer.Plat maps can indicate a need for a survey if there is any question about a structure or feature of a neighboring property extending past its boundaries, known as an encroachment.“If we notice any encroachments — fence is off the line, shed’s off the line — we can approach the seller before settlement and have any issues resolved,” says Sue Smith a real estate agent in Northern Virginia who completes 84% more sales than the average agent in her market.“I don’t like surprises, and I don’t like my clients to be surprised. I believe the settlement is a time to be happy as opposed to a time when you negotiate your contract. It’s a time to sign your papers and get your keys,” says Smith. Reviewing the plat map and ordering a survey in advance of closing will ensure that smooth and joyful experience.Easements shown on a plat map could also signal the need for a survey to get a closer look at an individual property.According to the National Association of Home Builders, the definition of an easement is the “right-of-way granted to a person or company authorizing access to the owner’s land; for example, a utility company may be granted an easement to install pipes or wires. An owner may voluntarily grant an easement, or in some cases, be compelled to grant one by a local jurisdiction.” Glenda Baker,a real estate agent in Smyrna, Georgia with 29 years’ experience specializing in single-family homes, illustrates just how much easements can affect property regulations.A previous client of Baker’s was under contract for a home that had a sewer easement by the storm drain runoff on the right and back sides of the house, which is “very common.”Because of her knowledge and familiarity with the local market, she knew because of a terrible flood that occurred in the area in 2009, her client would need a survey, “because these setback lines on these drains change if there’s been a flood,” and sure enough, the flood map had changed...By a lot.She pressed her client, who did not want to spend $650 on the survey, and it was a good thing she did, because the survey revealed that the buffer on the storm drain had extended from 7 feet to 25 feet. This decreased the building area on the lot. That meant in a worst-case scenario, if something irreparable happened to the house (like it burned to the ground), they could not rebuild a house of the same size that would be anywhere close to the same value.There are all kinds of easements that can run through a property and prevent the owner from building any kind of addition, like a pool, fence, or shed.
