Land Surveying questions, answered by experts

Surveys completed by licensed surveyors can be recorded with a local surveying records office, and in most cases, they will be. Filing survey reports categorize them as legal documents, and they can be used whenever legal documentation of your property’s boundaries is needed. While you’re not required to file survey documents, it’s a good idea to do so. 

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.

Costs vary, but you can expect to spend between $1,000 and $4,000 to prepare land for a mobile home or before you build a house. You’ll need to clear enough land for the foundation, which may require leveling or grading, as well as removing trees, stumps, and plants. Don’t forget to plan for permits and fees and the installation of a gas line, water line, and sewer main.

Before property transactions or major improvements to ensure accuracy.
