Land Surveying questions, answered by experts

Land surveys don’t technically expire. They do serve as a point of reference and a snapshot of your property, though, so as soon as you make changes to your property (and even if your neighbor makes certain changes to theirs), your existing land survey becomes inaccurate, and a new one must be done. Even if you don’t make any changes to your property, many states only guarantee the accuracy of a land survey for five to ten years.

You should always calculate real estate development costs on a case-by-case basis, so there’s no specific formula to estimate your total. You should speak with a local construction manager to see what you’ll need to do in terms of clearing and leveling the land, connecting utilities, and pulling permits for construction. A professional will be able to get you an accurate estimate for land development.

It is almost always necessary to hire a land surveyor near you to ensure your fence sits on the right side of the property line. Mistaking the shape of your property can lead to fines and costly changes if you have to move or adjust the privacy fence—not to mention some surly looks from your neighbor. We recommend jumpstarting your fence planning in the spring to ensure there is plenty of time to map out your plan before construction season.

To hire a land surveyor, you need to start by searching online for reputable professionals in your area. Here are a few steps to take when making a shortlist:

  • Browse land surveyor service website

  • Check credentials

  • Read customer reviews

  • Find their contact information

  • Call or email to inquire about more information

  • Ask how far they travel, if you’re some distance away

  • Find out how they charge for their services

  • Ask about schedule and turnaround times

  • Repeat these steps for one to two other services and compare pricing

If a buyer pays for a survey, the surveyor they hired will only provide results to them. It’s up to the buyer whether they share the survey results with the seller or not, even if they ultimately walk away from the deal. It’s considered good faith to share the results with the seller, though, especially if you back out of the deal, as the seller can then provide that survey to future interested parties.
