Pole Barn Cost by Size: 24×24, 30×40, 40×60, 50×100, and More
Pole barn cost by size is usually the first thing buyers want to know, and it is the right question to start with. The footprint of your building is the single biggest driver of your total project cost, and getting a realistic number for your specific size early in the planning process saves a lot of headaches later. This guide breaks down what common pole barn sizes actually cost based on real completed projects from Steel Structures America across Idaho, Washington, Oregon, Colorado, and Montana.
These are not manufacturer estimates or national averages. They are determined from real recent project data, which means you are seeing what buyers in this region actually spent on buildings of each size.
How to Read These Numbers
Each size below shows three numbers: the low end, the median, and the high end from our recently completed project records. Here is what those mean in practice:
- Low end: Reflects a basic, leanly finished build, often gravel floor, minimal doors, no insulation, or a simpler site situation.
- Median: The midpoint across all projects of that size. This is the most useful planning number for a functional, complete build with a concrete slab and standard features.
- High end: Reflects fully finished projects with premium upgrades, complex sites, specialty features, or commercial-grade specifications.
For more detailed explanation of these costs look at our article answering how much does a pole barn cost.

*These high-end figures include outlier commercial projects that are not representative of typical shop or garage builds. Use the median as your primary planning reference.
24×24 Pole Barn Cost
A 24×24 pole barn gives you 576 square feet, which is right-sized for a basic two-car garage, a small hobby shop, or a storage building for equipment and recreational gear. At 41 recently completed projects in our data, this is one of our well-documented sizes.
| Finish Level | Typical Cost |
| Basic shell, gravel floor, minimal doors | $24,000 to $30,000 |
| Functional build with concrete slab and one overhead door | $34,000 to $45,000 |
| Finished with insulation, electrical, and upgraded doors | $55,000 to $80,000+ |
The 24×24 is the smallest footprint most buyers find genuinely useful. If you are storing two vehicles and need room to move around them, 24×24 works. If you want a workspace beyond just parking, consider stepping up to a 24×30 or 30×40.
Wall height matters at this size too. A standard 10-foot wall works fine for a basic garage. If you want a loft, RV clearance, or room for a car lift, you will need at least 12 to 14 feet, which adds to the cost.
30×40 Pole Barn Cost
The 30×40 is the most popular pole barn size we build, with 178 recently completed projects in our data. At 1,200 square feet, it handles a three-car garage, a solid hobby shop, a small contractor storage building, or a combination of all three.
| Finish Level | Typical Cost |
| Basic shell, gravel floor, one standard door | $30,000 to $45,000 |
| Functional build with concrete slab, one or two overhead doors, basic electric | $60,000 to $80,000 |
| Well-finished with insulation, full electrical, upgraded doors | $90,000 to $130,000+ |
Our project median for 30×40 builds is $70,000, which is the most honest starting point for a complete, functional building. If you see quotes significantly below that, ask what is not included. Concrete alone on a 30×40 runs $8,000 to $16,000, and that is before you add doors, electrical, or any finishing work.
30×40 Cost by Wall Height
Wall height is one of the more impactful variables within the same footprint. Here is how it plays out across our 30×40 project data:
| Wall Height | Low End | Median | High End | Projects |
| 12-foot walls | $44,000 | $70,000 | $209,000 | 38 projects |
| 14-foot walls | $35,000 | $68,000 | $215,000 | 54 projects |
| 16-foot walls | $46,000 | $72,000 | $149,000 | 66 projects |
| 20-foot walls | $79,000 | $92,000 | $252,000 | 5 projects |
The medians across wall heights are relatively close because wall height is just one of many variables at play in each project. The bigger spread comes from what is included in the finish, not just how tall the walls are.
40×60 Pole Barn Cost
The 40×60 is the workhorse size. At 2,400 square feet, it is the go-to footprint for serious contractor shops, farm equipment storage, large garages, and commercial-adjacent builds. We have 140 recently completed projects at this size, making it one of our strongest data sets.
| Finish Level | Typical Cost |
| Basic functional build with concrete and standard doors | $60,000 to $80,000 |
| Well-equipped shop with insulation and full electrical | $100,000 to $140,000 |
| Premium finish with HVAC, spray foam, upgraded doors and lighting | $160,000 to $200,000+ |
Our project median for 40×60 builds is $120,000. This is where we see the biggest gap between what buyers expect based on kit pricing they research online and what a complete, finished building actually costs. A steel kit for a 40×60 might run $20,000 to $35,000. Once you add a concrete slab, erection labor, overhead doors, electrical, and basic insulation, you are in a very different price territory.
40×60 Cost by Wall Height
| Wall Height | Low End | Median | High End | Projects |
| 14-foot walls | $74,000 | $118,000 | $179,000 | 12 projects |
| 16-foot walls | $60,000 | $117,000 | $249,000 | 105 projects |
| 18-foot walls | $89,000 | $156,000 | $261,000 | 13 projects |
The jump from 16-foot to 18-foot walls reflects the additional steel, taller overhead door requirements, and sometimes more complex engineering that comes with extra height. For most shop uses, 16-foot walls are the sweet spot between cost and function.
40×40 Pole Barn Cost
The 40×40 sits between the popular 30×40 and 40×60 footprints. At 1,600 square feet, it gives you more depth than a 30×40 without committing to the full 2,400-square-foot footprint of a 40×60. We have 46 recently completed projects at this size.
| Finish Level | Typical Cost |
| Basic functional build | $58,000 to $80,000 |
| Well-equipped shop | $90,000 to $120,000 |
| Premium or commercial finish | $140,000 to $200,000+ |
The median for 40×40 builds in our data is $94,000. This footprint is a good fit for buyers who need more square footage than a 30×40 provides but find the 40×60 larger than they need or can budget for.
40×80 Pole Barn Cost
A 40×80 gives you 3,200 square feet of usable space. This is the size range where you start to see larger contractor operations, serious RV and boat storage setups, multi-bay shops, and larger agricultural buildings. We have 28 recently completed projects at this footprint.
| Finish Level | Typical Cost |
| Functional build, basic finish | $71,000 to $110,000 |
| Well-outfitted shop with full electrical and insulation | $140,000 to $200,000 |
| Premium or commercial finish | $250,000 to $450,000+ |
Our project median for 40×80 builds is $174,000. The high-end figure in our data ($1.25 million) is an outlier commercial project that is not relevant to most buyers. If you are planning a personal or agricultural 40×80, the $140,000 to $200,000 range is a realistic planning target for a well-finished build.
50×100 Pole Barn Cost
The 50×100 is commercial and agricultural territory. At 5,000 square feet, this footprint serves large farm shops, full contractor operations, equipment storage for multiple pieces of large machinery, and small commercial uses. We have 10 recently completed projects at this size.
| Finish Level | Typical Cost |
| Functional build, basic finish | $126,000 to $175,000 |
| Well-outfitted farm or contractor shop | $200,000 to $280,000 |
| Commercial-grade or premium finish | $350,000 to $506,000+ |
The median for 50×100 builds is $235,000. At this scale, concrete alone is a major line item, and electrical and insulation scale up proportionally. The per-square-foot cost starts to work in your favor versus smaller buildings, but the absolute dollar commitment is significant. Budget carefully and get detailed bids before committing to a site.
60×80 Pole Barn Cost
The 60×80 footprint gives you 4,800 square feet and starts to move into genuinely commercial-scale territory. Buildings this size are used for large equipment storage, farm operations, light commercial warehousing, and large multi-vehicle shops. We have 7 recently completed projects at this size.
| Finish Level | Typical Cost |
| Functional build | $196,000 to $220,000 |
| Well-equipped commercial or farm shop | $240,000 to $350,000 |
| Premium commercial finish | $400,000 to $508,000+ |
The median for 60×80 builds in our data is $241,000. With fewer projects in this size range, the data has less depth than our most common sizes, so treat these figures as directional planning numbers and rely more heavily on a detailed contractor quote for your specific site and spec.
What These Numbers Do Not Include
The figures above reflect turnkey construction costs, but there are project components that may or may not be included depending on how a contractor structures their quote. Before you use any of these numbers to set a budget, confirm the following are accounted for:
- Permits and local fees: Vary by jurisdiction and building size. Budget $1,000 to $5,000.
- Site grading and clearing: Not included if your site needs significant work. Can add $3,000 to $20,000+.
- Utility connections: Running power to a remote building location can add $5,000 to $20,000+ depending on distance.
- HVAC: Mini-splits, unit heaters, and in-floor radiant systems are separate from the base build.
- Plumbing: A bathroom or utility sink adds $5,000 to $15,000+ depending on your setup.
We also have a separate article on the factors that affect pole barn prices.
Getting an Accurate Quote for Your Size
Use these numbers to calibrate your expectations before you talk to contractors. Here is how to get a real quote you can build a budget around:
- Lock in your footprint before calling. Contractors need a specific size to quote accurately.
- Decide on your wall height. It affects material cost, door sizing, and sometimes engineering requirements.
- Know your concrete plan. Slab thickness, reinforcement type, and any special finishes need to be specified.
- List your doors. Number, size, and whether you need insulated doors or specialty clearances.
- Ask for a fully itemized quote. Material, labor, site work, and clear exclusions listed separately.
