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.

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

Measure from zero on a measuring tape by placing the metal hook right up against the edge of what you need to measure. You can also latch the hook onto an open edge—of, say, a table—to accurately measure as well. If you begin at the 1-inch mark, you'll need to subtract an inch from your total.

A few different types of land surveys can help determine certain features and boundaries of your property. These include:

• Boundary surveys describe the actual borders of a property. These are generally required when trying to get construction permits issued. 

• Location surveys provide much of the same information as a boundary survey but also include in-depth information about any improvements made to your property. 

• Mortgage location surveys are usually required by lenders and title companies before financing or offering an insurance policy. 

• Site-planning surveys are done before applying for building permits and can be issued before any major home improvements. 

• Topographic surveys provide a formal map of land elevations. It can also describe the location and size of natural features and any land improvements.
