Land Surveying questions, answered by experts

Permit requirements to clear land vary by municipality, so whether or not you need permits depends on where you live and what you’re removing from the land. Some building departments will require permits for any underground work or excavation, meaning grinding down tree stumps on your property would require permits. Others mandate individual permits for each tree you remove. You can contact your local building department or a land-clearing specialist near you to see if permits are necessary for your job.

Several government-backed lending programs can help first-time home buyers purchase a home with little money down. FHA, USDA, and VA loans are options for qualifying borrowers, though many conventional mortgage lenders will lower down payment rates to as low as 3 percent.

Land surveying can help give clear guidance on your property boundaries for numerous situations. And in some cases, having your land surveyed is a requirement. Some common reasons to have your land surveyed include:

  • Planning for construction projects, like building a fence

  • Locating utilities, such as plumbing fixtures

  • Settling property line disputes 

  • Creating subdivisions 

  • Meeting mortgage requirements

  • Selling your property

Soil testers and licensed excavators are often the professionals you hire if you need a perc test. In some cases, structural engineers will also be able to conduct the test for you. In many municipalities, you’ll need your professional on-site to dig and fill the holes with water, as well as a representative from your local building department or health department. That representative is the individual who will determine whether your test passes or fails.

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.
