When you're planning a new garage or shop building in Waverly, Humphreys County, or the surrounding Middle Tennessee area, one of the first decisions you'll face is whether to build post-frame (pole barn) or stud-frame (stick-built). Both construction methods work well here, but they differ in foundation requirements, cost, and the types of projects where each makes the most sense.
What's the difference between post-frame and stud-frame construction?
Post-frame buildings—commonly called pole barns—are supported by heavy vertical wooden beams spaced approximately eight feet apart. These treated sawn wood beams are buried four to six feet into the ground, which means the building doesn't need a continuous concrete foundation. Because the posts are set eight feet apart and the roof is supported by clear-span trusses, there are no interior load-bearing walls required, which gives you wide-open space inside.
Stud-frame structures, on the other hand, are built much like a house. Vertical studs are typically spaced 16 inches apart, and the entire building sits on a continuous concrete foundation support system—either a crawlspace or a slab. This method is what most residential contractors use, and it's a good fit for smaller buildings or when you want a garage that matches the look and feel of your home.
| Feature | Post-Frame (Pole Barn) | Stud-Frame (Stick-Built) |
|---|---|---|
| Foundation | Posts buried 4–6 feet into the ground | Continuous concrete perimeter or slab |
| Vertical support spacing | Approximately 8 feet apart | 16 inches apart |
| Interior load-bearing walls | Not required | May be required for larger spans |
| Best for | Large, open workshops and ag buildings | Smaller garages and residential-style buildings |
Which costs less—post-frame or stud-frame?
Post-frame garages usually cost less than stick-built garages, often by 20–25%, because they require less concrete and a simpler foundation. That difference becomes even more noticeable as building size increases. A continuous concrete perimeter foundation can account for 10–15% of a stick-built project's total budget, and when you're talking about a larger shop or agricultural building, that adds up quickly.
Industry-wide, pole barns can cost 30–50% less than a comparable stick-built structure, though actual savings depend on size, finish level, and site conditions. For anything smaller than roughly 30 feet by 30 feet by 12 feet tall, the economics can shift, and stick-frame may make more sense. If you need a heavily partitioned layout with multiple interior rooms, stick-frame construction may also be a better fit.
The cost of either type of building depends on far more than just square footage. A bare shell costs far less than a finished, insulated workshop with utilities, overhead doors, windows, and siding upgrades. Roof style, door size and number, site preparation, and your choice of materials all play a role. That's why we always recommend getting a real quote based on your specific needs and property.

What building codes and permits apply in Humphreys County and Middle Tennessee?
Building permit requirements and engineered-plan rules vary significantly across Middle Tennessee, so it's important to confirm what applies to your specific property. The State of Tennessee has a list of building codes, but local governments adopt, withdraw from, or become exempt from those state codes. Rural counties vary significantly in permitting requirements, and some unincorporated areas have no building code enforcement at all.
In unincorporated Humphreys County, a building permit is not required. The cities of Waverly, New Johnsonville, and McEwen have their own requirements, so it's important to confirm with the municipality where your building will be sited. Other counties and cities in our Middle Tennessee service area each administer codes locally, and the rules can differ even between neighboring counties. Tennessee agricultural buildings used for farming purposes may be exempt from state building code requirements in some rural counties, but this varies by jurisdiction.
Whether engineered or PE-stamped plans are required also depends entirely on the local codes department for your county or city. Many rural Middle Tennessee counties do not require engineered or stamped plans, while some municipalities do. PAC Building Pro provides building drawings engineered for the local snow and wind loads used in Middle Tennessee (10 psf ground snow load and 90 mph wind speed for most of this area), and we can provide PE-stamped plans on request when a county requires them, though that adds cost and lead time.
How do I choose between post-frame and stud-frame for my property?
The right choice depends on your building's size, use, and what you want the finished building to look and feel like. Post-frame construction shines for larger buildings where you need wide-open interior space—workshops, equipment storage, hay barns, and commercial shops. Because there are no interior load-bearing walls required, you can design the interior layout however you like without worrying about structural support.
Stud-frame construction is often the better choice for smaller garages, especially if you want the building to match the architectural style of your home or if you're building in a subdivision or residential neighborhood. It's also a good fit if you plan to partition the interior into multiple rooms or if your local codes or homeowners' association require a specific type of construction.
Both methods can be insulated, finished with a variety of siding and roofing materials, and customized with windows, doors, and utilities. The structural difference is mostly hidden once the building is complete, so your decision will come down to cost, building size, and what works best on your site.
Common sizes and uses
For post-frame garages and shops, common sizes in Middle Tennessee range from 24×30 or 30×40 for a basic two- or three-car garage up to 40×60 or larger for farm equipment storage or a commercial workshop. A basic shell typically costs far less than a finished, insulated building, and the final cost depends on roof style, door size and number, siding choice, and whether you're adding utilities or interior finish work.
For stud-frame garages, anything smaller than roughly 30 feet by 30 feet is usually the better fit economically. A 24×24 or 24×30 stick-built garage is a popular choice for residential properties in Waverly, Erin, Dickson, and other nearby towns where the building needs to blend in with the surrounding homes.
Does PAC Building Pro serve my area?
Yes, if you're in Humphreys County or the surrounding Middle Tennessee counties. PAC is based in Waverly, the county seat of Humphreys County, and we build custom post-frame and stud-frame garages and shops on your property throughout a roughly 70-mile radius. That includes Humphreys County (Waverly, New Johnsonville, McEwen, Hurricane Mills), Houston County (Erin, Tennessee Ridge), Benton County (Camden, Big Sandy), Perry County (Linden, Lobelville), Hickman County (Centerville), Dickson County (Dickson, White Bluff, Burns, Charlotte), Henry County (Paris), and many other nearby counties.
We also build and deliver to the larger metros in our reach—including Clarksville, Nashville, Columbia, Jackson, and Franklin—where we compete on custom work, delivery capability, and price. For nearby western Kentucky locations like Murray, Cadiz, and Hopkinsville, we deliver prefab packages such as portable buildings and steel carports, but we do not perform on-site pole barn or stud-frame construction across the state line.
Financing and payment options
Custom post-frame and stud-frame garages and shops built on your property are available with financing and cash payment options. These are not rent-to-own buildings—they're permanent structures built on your land. We also offer delivered prefab metal garages, which are available with rent-to-own (no credit check), cash, and free delivery within 30 miles of Waverly. The terms differ depending on the type of building, so give us a call to discuss what works best for your project.
Frequently Asked Questions
Do I need engineered plans for a pole barn in Humphreys County?
In the unincorporated areas of Humphreys County, engineered or PE-stamped plans are typically not required, though city limits (Waverly, New Johnsonville, McEwen) may have different rules. Other counties and municipalities across Middle Tennessee vary in their requirements, so it's important to confirm with your local codes office before you start your project.
Can I finance a custom pole barn garage in Middle Tennessee?
Yes, PAC Building Pro offers financing for custom post-frame and stud-frame garages and shops built on your property. These buildings are not available on a rent-to-own basis, but we do offer delivered prefab metal garages with rent-to-own and no credit check options.
Which is better for a 30×40 shop—post-frame or stud-frame?
For a 30×40 shop, post-frame construction is usually the more cost-effective choice and gives you wide-open interior space without load-bearing walls. Stud-frame can work as well, but it typically costs more due to the continuous concrete foundation and closer stud spacing.
