12×20 Sheds — Prices, Styles & What Fits
At 240 square feet the 12×20 is the crossover point: it is offered as a shed, as a single-car garage, and as a two-story. This is the first size where you should assume a building permit is required and plan for it rather than hope around it.

What actually fits in 12×20
Fits comfortably
- A single car or truck in the garage version, with storage still left at the back
- A full workshop with a table saw, benches on two walls, and a materials rack
- A tractor with a mid-mount deck plus attachments
- Two-story models get a genuinely usable second floor at this footprint
Where 12×20 gets tight
- Over 200 sq ft means a building permit in most townships — budget the time, not just the money
- A 20-foot building needs real delivery clearance; a tight gate or a sharp turn may force an on-site build
Still not sure? Our shed size calculator works backwards from what you need to store.
12×20 is 240 sq ft — what that means for your permit
240 sq ft — over the 200 sq ft threshold most local townships use, so plan on a building permit. Pennsylvania’s state UCC exemption runs to 1,000 sq ft, but the local number is the one that governs you and it is almost always far lower. On the upside, a permitted structure at this size is inspected and documented, which matters at resale. Our $25 permit review finds your township’s exact requirement and prepares the paperwork, including your site plan and impervious coverage worksheet.
Pennsylvania’s statewide code generally exempts detached accessory structures under 1,000 sq ft from a state building permit — but almost every municipality sets its own, lower threshold. Two hundred square feet is the most common trigger; some townships use 100. Harrisburg requires a building permit at 200 sq ft and up, Erie at 100, Philadelphia treats 120 sq ft as the line, and Pittsburgh wants a zoning certificate at any size. A zoning permit is close to universal even for small sheds, and electric, plumbing, or heat are separate trade permits no matter how big the building is.

Getting a 12×20 to your property
A 12×20 is delivered fully assembled and set in place. Delivery is $5 per mile from Parkesburg, PA — most deliveries in our area run $200 to $600. We serve customers within 50 miles of Parkesburg, PA.
If the truck can’t reach the spot — narrow gate, back yard, steep grade — we build the same 12×20 on site instead. That adds 30% for a standard shed or garage, 20% for two-story and modular buildings.
A 12×20 needs a level pad. A gravel pad starts at $945; poured concrete starts at $4,230. We supply and install the wedge anchors that tie the building down, with length and spacing set by your township’s code. Gravel vs. concrete →
12×20 questions we get asked
How much does a 12x20 shed cost?
Our 12×20 buildings start at $5,200 in LP SmartSide siding, delivered fully assembled within 50 miles of Parkesburg, PA. Price depends on the style you choose and the siding — vinyl runs roughly 10–25% higher than LP SmartSide. Every 12×20 model and its starting price is listed on this page.
How many square feet is a 12x20 shed?
A 12×20 building is 240 square feet. That number matters because most townships set their permit threshold by square footage, not by what you call the building.
Do I need a permit for a 12x20 shed?
240 sq ft — over the 200 sq ft threshold most local townships use, so plan on a building permit. Pennsylvania’s state UCC exemption runs to 1,000 sq ft, but the local number is the one that governs you and it is almost always far lower. On the upside, a permitted structure at this size is inspected and documented, which matters at resale. Our $25 permit review finds your township’s exact requirement and prepares the paperwork, including your site plan and impervious coverage worksheet.
Is a 12x20 building delivered assembled?
Yes. A 12×20 is delivered fully built on our truck and set on your prepared pad — usually in under an hour once we are on site. Delivery is $5 per mile from Parkesburg, PA. If your site cannot be reached by truck, we can build the same building on site instead.
Do you have a 12x20 shed in stock?
Yes — we currently have 7 12×20 buildings on the lot ready for delivery. In-stock buildings are shown on this page with real photos of the actual unit, not a catalog rendering.
