If you're shopping for a portable building in Middle Tennessee, the first big question is usually "what size do I actually need?" It's easy to either overbuy—spending more than necessary—or end up with a building that's cramped from day one.
The good news? Sizing a shed, barn, utility building, or cabin isn't rocket science. It just takes a little planning and honest thinking about what you'll store or do inside. Let's walk through how to pick the right size for your property and your life here in Tennessee.
Start With What You're Storing or Using It For
The simplest way to size a portable building is to list what's going in it—or what you'll be doing inside. Be specific. "Yard stuff" is vague; "riding mower, push mower, two trimmers, hand tools, and a small workbench" is something you can measure and plan around.
Here are some common uses and the sizes that typically work:
- Lawn and garden storage (mower, tools, bags of soil): 8×10 or 10×12 is usually plenty.
- Workshop or hobby space: 10×16 to 12×20 gives you room to move and add a bench or two.
- ATV, UTV, or small tractor storage: 12×20 or 12×24 handles most machines with space to walk around.
- Multi-use (storage + workspace): 12×24 or 12×32 lets you zone the interior.
- Small cabin or office: 12×32 or 14×40 offers real living or workspace, especially with a loft option.
If you're not sure, it's often smarter to go one size up than to regret being cramped later. Storage has a way of expanding over time.
Common Portable Building Sizes and What Fits
Here's a quick reference for some of the most popular sizes and what they can realistically hold:
| Size | Square Feet | Good For |
|---|---|---|
| 8×10 | 80 | Push mower, basic tools, seasonal items |
| 10×12 | 120 | Riding mower, garden tools, small workbench |
| 10×16 | 160 | Mower + tools + workspace or shelving |
| 12×20 | 240 | ATV, UTV, lawn equipment, or shop space |
| 12×24 | 288 | Two ATVs, tractor, multi-zone storage |
| 12×32 | 384 | Workshop, small cabin, or mixed storage/workspace |
| 14×40 | 560 | Cabin, home office, large shop, or equipment barn |
Keep in mind that usable space shrinks once you add shelves, benches, or equipment. A 10×12 building sounds roomy on paper, but a riding mower alone takes up a big chunk of that footprint.

Measure Your Gear (and Your Property)
Before you settle on a size, grab a tape measure and check the dimensions of anything big you plan to store. Riding mowers, ATVs, tractors, and motorcycles all have specific footprints—and you'll want at least a couple feet of clearance on all sides so you can actually get in and out.
Also think about your property:
- Do you have a flat spot big enough for the building you want?
- Are there setback rules from your property line? (Most Tennessee counties require a few feet.)
- Will the building fit through any gates or past trees during delivery?
Portable buildings are delivered fully built, so access matters. PAC can help you think through placement when you call for a quote.
Don't Forget About Height and Doors
Size isn't just length and width. Ceiling height and door size make a huge difference, especially if you're storing tall equipment or want to add a loft later.
Most standard portable buildings come with a single door, but if you're storing a UTV, ATV, or riding mower, a double door (or even a roll-up door on some models) makes life much easier. And if you're thinking workshop or cabin, consider windows for light and ventilation.
Think a Few Years Ahead
One of the most common regrets we hear is "I wish I'd gone bigger." If your budget allows, consider your needs a few years out. Will you buy another piece of equipment? Take up a new hobby? Need space for seasonal decorations as your family grows?
Portable buildings hold their value well, especially in Middle Tennessee where weather and rural living mean people always need good storage. A slightly larger building now can save you from needing a second one later.
Rent-to-Own Makes Sizing Easier
If you're torn between two sizes and worried about upfront cost, rent-to-own can take the pressure off. PAC Building Pro offers rent-to-own with no credit check on all portable buildings—sheds, barns, cabins, and utility buildings. You can get the size that actually fits your needs without waiting or compromising.
And because delivery is free within 30 miles of Waverly, you're not paying extra to get a larger building to your property.
Local Considerations for Middle Tennessee
Here in Middle Tennessee, a few things are worth keeping in mind:
- Weather: Our humid summers and wet springs mean ventilation matters. Make sure your building has airflow, especially if you're storing anything that can rust or mildew.
- Terrain: Many properties around Waverly, Dickson, and surrounding areas have slopes or uneven ground. Talk to PAC about site prep and leveling if your spot isn't naturally flat.
- Critters: Mice, snakes, and other wildlife love dark, cluttered sheds. A larger building that lets you organize and keep things off the floor helps a lot.
Frequently Asked Questions
What's the most popular portable building size in Tennessee?
The 10×16 and 12×20 sizes are extremely popular because they're versatile—big enough for real storage or a workspace, but not so large they overwhelm a typical yard. That said, the "right" size depends entirely on what you're using it for.
Can I add on to a portable building later if I need more space?
Portable buildings are delivered as complete units, so expanding one later isn't practical. That's why it's usually smarter to go a size up now if you're on the fence. You can always leave extra space empty at first.
Do I need a permit for a portable building in Middle Tennessee?
It depends on your county and the size of the building. Some counties require permits for buildings over a certain square footage, and some have setback rules from property lines. PAC can point you in the right direction, but it's always smart to check with your local building department before delivery.
How does rent-to-own work on portable buildings?
Rent-to-own lets you take delivery of your building and make manageable monthly payments over time. PAC Building Pro offers rent-to-own with no credit check, so approval is simple and fast. You own the building outright once the term is complete, and there's no penalty for paying it off early.
