How a Perk Test Works When You Buy Land to Build in Livingston, TN

I'm Bridget Salazar, OC Homegirl. I'm a REALTOR® with The Realty Firm and a Certified Residential Appraiser, and Livingston is my home base.

Somebody calls me about a piece of land in Livingston and asks one question before anything else. Can I build on it?

Most of the time the answer runs through a perk test. People also call it a soil test or a soil evaluation. It is the step that decides whether the ground will take a septic system.

No septic approval, no permit for a house. That is why I bring it up before anybody talks about price.

This is a general explanation and not legal advice. Your contract sets the terms, and the permitting offices set the rules for the property.

A septic system does not make anything disappear. It treats waste and then lets the ground absorb what is left. So the whole question is whether this dirt, in this spot, will take water at a usable rate.

Somebody qualified digs into the soil and reads it. What they are checking:

• How deep the usable soil goes before it hits rock.
• What the soil is made of and how water moves through it.
• Signs that the ground stays wet or holds a high water table.
• Slope, and how the site drains.
• Whether there is room for a drain field plus a reserve area.

Around Livingston and the rest of Overton County you run into shallow soil over rock, and wet bottoms along the creeks. Two tracts that look identical from the road can read completely differently once somebody digs.

This is not something you do yourself with a posthole digger and a bucket of water, whatever the internet tells you.

In Tennessee, septic permitting runs through the state Department of Environment and Conservation. There is a local environmental field office that covers our area, and that office is the first call. Ask them what they need for your parcel and who is approved to do the soil work.

Sellers sometimes already have a test. Ask for the paperwork, not the summary. You want to see what was approved, where on the tract, and when.

Then confirm it still stands. Rules change, and ground changes after logging or grading. An older approval may need another look before you count on it.

This is the part buyers misread most often.

A pass is not a blanket yes for the whole property. It approves a system of a certain type and size, in a specific area of the tract.

The size is tied to the house you intend to build, and it is usually counted in bedrooms. Decide later that you want a bigger house and you may be back at the field office.

A pass also ties up part of your land. The drain field and the reserve area have to stay clear. You cannot put a shop, a driveway or a pond on top of them.

So place the septic area on the map before you settle on a building site. I have watched people pick the view first and then find out the only approved ground is right where they wanted the house.

A failed result does not always mean the land is unbuildable. It means that spot will not take a standard system.

From there the options usually look like this:

• Test a different part of the tract.
• Look at another kind of system, which costs more to put in and more to keep up.
• Use the land for something other than a house.

All three change what the land is worth, and that matters whether you are buying or selling land. A tract with approved soil work does not sell like a tract with a question mark on it.

I price both against real closed land sales, the way I was trained to as an appraiser. When I am your listing agent, that number is a pricing opinion built with appraisal methods and not a formal appraisal.

Do not treat this as a detail to sort out after closing.

What I do with a buyer:

• Ask the listing agent in writing whether soil work exists.
• Call the field office about the parcel before we write anything.
• Build the offer so the purchase depends on an approved result, with a deadline we can actually hit.
• Get the soil work ordered the day we go under contract.

Scheduling takes as long as it takes, and weather affects it. Starting late is how a deadline gets missed. The order of the whole purchase is on how I help buyers, and the land version is on buying land and buying land in Livingston.

The rest of my list for acreage is in questions to ask before you offer on land in Overton County.

Send me the address or the parcel number before you write anything. I will find out what soil work exists and what land like it has been selling for.

Moving here from out of state? Start with relocating to the Upper Cumberland, and then Livingston for the town itself.

Questions about permits go to the environmental field office. Questions about financing land go to your lender. The contract sets the terms.
