Buying land in Southside can feel simple at first. You find a few acres, picture the home or shop you want, and start doing the math. But with land, the real question is not just what the property costs. It is whether the tract can legally and practically support your plan. If you are thinking about buying land or small acreage in Southside, this guide will help you focus on the checks that matter most before you close. Let’s dive in.
Why due diligence matters first
In the Southside area of Montgomery County, rural land is often tied to low-density residential use, farmland preservation, forestry, wildlife management, and recreation in county growth-plan materials. That means many properties may look flexible on the surface, but your intended use still needs to fit the parcel’s rules and conditions.
This is where many buyers can save time, money, and stress. A tract that looks perfect online may have limits tied to zoning, frontage, septic feasibility, floodplain status, or utility access. The best land purchase is usually the one that works on paper before you fall in love with the view.
Check zoning before anything else
Zoning is one of the first things you should verify for any Southside-area parcel. Montgomery County planning and zoning are handled through the Clarksville-Montgomery County Regional Planning Commission, and county GIS tools can help you review parcel details, zoning, and FEMA flood-zone layers.
Montgomery County’s zoning resolution says parcels without a zoning designation default to the AG Agricultural District. In AG, permitted uses include agricultural uses and single-family dwellings, but the site standards are especially important for small-acreage buyers.
AG standards that affect small acreage
For dwellings and accessory buildings in AG, the county requires:
- At least 1.5 acres
- At least 50 feet of frontage on a public road
- At least 150 feet of lot width at the front building line
These standards can make or break a plan. A parcel might have enough total acreage, but still fall short on frontage or width where it matters.
What this means for barndominiums and hobby farms
If you are planning a barndominium, hobby farm, or a home with a large shop or barn, do not assume there is a special shortcut. In practice, a barndominium is usually evaluated as a residence plus any accessory shop or barn components, using the existing zoning and site rules.
The county also says that if a use is not specifically listed, the planning commission may determine the proper zone classification if the use is similar and compatible with listed uses. That is another reason to verify your concept early instead of relying on assumptions.
Verify water, sewer, and septic options
Utilities are one of the biggest variables with rural land. County growth-plan materials say new water lines or upgrades needed for new development are paid by the requesting property owner. They also note that public wastewater service should be verified parcel by parcel rather than assumed.
In plain terms, just because a tract is on the market does not mean it has a simple path to public water or sewer. Before you buy, you want to know exactly what serves the property now and what you may need to pay for later.
If there is no public sewer
You do not necessarily need public sewer to build. But you do need a septic path that can actually be permitted.
TDEC says a conventional septic permit is required before starting dirt work or building the pad. That applies not only to residences, but also to accessory buildings like a garage, shop, or barn when septic service is needed.
If soil or site conditions are poor, TDEC says an alternative septic permit may be required. That process can also require an extra-high-intensity soils map prepared by a Tennessee-licensed soils consultant.
Why septic should be checked before closing
A tract can look ideal and still fail to support the septic solution you need. That is why septic feasibility should be part of your due diligence, not something you push off until after closing.
If the property already has a septic system, you should still ask for documentation. TDEC offers septic inspection letters that are commonly requested in real estate transactions.
Understand tract splits before you buy
If your plan includes dividing land later, pause and check the rules first. TDEC says a subdivision evaluation is required when dividing land into two or more lots, sites, or other divisions for future development where septic will be used.
That review requires a survey and soils map. There is an important exception, though. Dividing a tract into parcels that are all 5 acres or larger is not considered a subdivision for this septic-review purpose.
This matters if you are buying land for a future family split, investment plan, or resale strategy. A property that works for one homesite today may involve a very different process if you want multiple buildable parcels later.
Do not overlook well due diligence
If the land does not have public water, a private well may be part of the plan. Tennessee health guidance makes one thing clear: private well water should not be assumed safe just because a well exists.
The state says private wells should be tested on an ongoing basis, and buyers should ask for the driller’s registration number and the well log. If there is an existing well on the property, request as much documentation as possible during your due diligence period.
When well testing matters most
Well testing is especially important if:
- The property already relies on a private well
- You do not have records for the existing well
- The area has had flooding or other events that could affect water quality
- You are comparing the cost of public water access versus private well installation
TDEC also offers water samples for total coliform testing that are routinely requested for real estate transactions.
Confirm road frontage and access
Access is easy to overlook until it becomes a closing problem. Montgomery County’s permit checklist says that if the lot is on a state road, a TDOT letter may be needed instead of a county road-damage bond.
That means road frontage is not just about convenience. It can affect permitting and development steps. Before you close, make sure you understand whether the property fronts a public road, whether access is clear, and whether any added documentation may be required.
Review floodplain status early
Floodplain questions should come up long before you finalize building plans. Montgomery County requires a floodplain development permit before development begins if the parcel is in a Special Flood Hazard Area.
The county’s floodplain form asks whether the site is in a FEMA flood zone or floodway and whether a no-rise certification is attached where needed. This is one more reason the county GIS mapping tools are so helpful early in the process.
A beautiful tract near water or low-lying ground may come with added review, design limits, or permitting needs. It is much better to know that up front.
Know what a building permit does not cover
One of the most important land-buying lessons is that a building permit does not solve everything. Montgomery County building-code materials say a residential building permit is not zoning approval, floodplain compliance, a septic or sewer permit, or plumbing and electrical permits.
That distinction matters because buyers sometimes assume that once a permit is in motion, all major issues are cleared. In reality, each approval path may have its own requirements and timeline.
Common permit items to expect
County permit materials may require:
- Final plat or recorded minor plat when applicable
- A site plan showing lot lines and setbacks
- Septic permit
- Square footage and estimated construction cost
- Contractor license and insurance documents
- Road-access documentation when required
This is why land purchases tend to go more smoothly when you build your team early and follow the right order.
Bring in the right professionals at the right time
A practical order for Southside acreage is to verify the parcel and zoning first, then confirm water, sewer, and access, then test septic and soil feasibility, then check floodplain status, and after that line up the surveyor, builder, and permits.
That sequence can help you avoid spending money too early on plans for a tract that may not support your goals.
Professionals who can help
Depending on the property, your team may include:
- Surveyor if boundaries, frontage, access, or future splits are unclear
- Soils consultant if the tract is unimproved, has drainage concerns, or may need an alternative septic system
- Septic designer or installer after soil screening and before dirt work
- Well driller if there is no public water and a private well is part of the plan
- Licensed contractor after zoning, utility, septic, and floodplain questions are answered
Tennessee says a contractor’s license is required before bidding or negotiating any project costing $25,000 or more. The state also says that if you are hiring a contractor, that contractor should obtain the building permit rather than having the homeowner pull it on the contractor’s behalf.
A simple checklist for Southside land buyers
Before you move forward on land or small acreage in Southside, make sure you can answer these questions:
- What is the parcel’s current zoning?
- Does the tract meet AG standards for acreage, frontage, and width if AG applies?
- Is your intended use clearly allowed?
- Is there public water, public sewer, both, or neither?
- If sewer is not available, is there a workable septic path?
- If there is an existing septic system, what documentation is available?
- If there is a well, do you have records, a well log, and current testing information?
- Is access direct, legal, and adequate for permitting?
- Is any part of the tract in a flood zone or floodway?
- Will you want to split the tract later?
If you can answer those questions clearly, you are already in a much stronger position than many land buyers.
