foundation for storage shed
The foundation of a storage shed is the first and most important part of installation process!

Building the right foundation for a storage shed is extremely important. The photo on the left shows a great example of what a poor foundation and time can do to a shed. Regardless of how strong the building construction is, if the shed foundation is poor it will not stand the test of time.

Consult your Local Building Inspector

 

Before beginning to build any foundation for your shed, consult your local building inspector to determine what type of foundation you will need. The decision will be based on the height and size of your storage shed. Regardless of the size of your shed, a building inspector needs to make sure that the storage building is up to code for your local area.

Click here to learn more about the process of obtaining a building permit for your storage building.

Does my Shed Need a Foundation?

 

Generally, smaller sheds of up to 8×6 do not need a foundation. Small sheds can be rested on crushed stone with either treated wood foundations or concrete foundation blocks. Large sheds will need to have strong foundations. Considering Backyard Buildings smallest shed size is 8×8, all of our sheds will need a foundation setup prior to the arrival of one of our installers.

*Backyard Buildings Minimum Foundation Requirements:

*Prior to the arrival of the installer, your site must be level within 6″h. * Additional charges may apply if this requirement is not met. *

Tools/ Materials Needed:

Types of Foundations Used for Sheds

  1. Concrete slab foundations
  2. Wood foundations

Concrete Slab foundations:

concrete foundation for sheds
Concrete foundation shown here

We recommend our customers to use a concrete slab for their shed foundations. In preparation for the arrival of our professional installers, the build site must be properly leveled and should have natural drainage and no standing water. This will insure that your shed will remain strong and stable for many years to come.

Guidelines to Follow when Building Concrete Slabs (Not required, these are our recommendations)

  1. Your concrete slab should be the same width as the storage shed.
  2. The slab can be no greater than 1/4″ out of “square”.
  3. In certain markets that experience frequent hurricanes, 1/2″ x 8″ “J” type anchor bolts should be set in the concrete around the entire perimeter of the slab (except for the doorway) projecting approximately 2 1/2″ above the slab grade and approximately 1 1/2″ in from the edge.
  4. The finished slab surface needs to be at a minimum of 4″ above grade.

Wood Foundations:

Wood Foundation for shed installs

Wood foundations are typically built using solid concrete leveling blocks which are 8” x 16” and no more than 2” high. Each block is arranged in evenly spaced rows by placing one in each corner and at each break. These concrete leveling blocks will support the floor. If you choose not to use concrete leveling blocks, we recommend using pressure treated lumber to support the wooden floor frame.

 

 


Backyard Buildings suggested block count by sizes:

6X6 — 8

8X8 — 8

8X6 — 8

8X10 — 10

8X12 — 12

10X10 — 14

10X12 — 16

10X16 — 20

12X12 — 16

12X16 – 22

12X20 — 26

12X24 — 30

16X20 — 50 — *Piers or foundation may be required by state.

16X24 — 55 — *Piers or foundation may be required by state.

Don’t Forget the Frost Line…

 

Lastly, it’s important to consider the frost line of your region. If frost lines are not considered, your shed may move due to seasonal freeze and thaw changes. This means that the foundation will need to be built to the frost line. Once again, you will need to contact your local building inspector to determine the frost line for your area.

What Shed Foundation is Right for Me?

 

While there are other methods to building shed foundations, these are the two types we suggest to use. Choosing the right foundation for your storage building will make the entire process of installing a shed much easier and will allow your shed to stand up strong to the test of time! Once you build the foundation, we can do the rest!

If you have any general questions regarding foundations, please contact Backyard Buildings at 855-853-8558.

Posted on October 6, 2013 at 10:58 am

Posted by bdeitsch

Hi Paul,

I think it might depend on which type of deck blocks you’re talking about. If you’re referencing the deck blocks that you might find at Home Depot, they have one that can be used for 4×4’s. 4×4 fits in the plate. Some of the deck blocks are suited to 2x4s, not the 4×4’s our installers use for the foundations of our sheds. I hope that helps. Have a great day!

I am going to put a 7 x 7 or 8 x 8′ vinyl shed. The ground is out of level, and I have a TON of extra dirt (dug out a pool)
Instead of digging to level the ground, can I build up the low spot with the extra dirt I have. (I am trying to get rid of it)

Posted on October 21, 2013 at 10:52 am

Posted by bdeitsch

Hi Ken. Yes, that is fine. Besides the obvious, having a level shed foundation is important to prevent an abundant amount of sitting water. For example, if you have large holes underneath your building, puddles of water will form causing many different problems. Go ahead and use up as much dirt as needed… Have a great day!

I live in Florida and have sandy soil. Can I just level the ground for a 4×6 vinyl/resin shed and put the shed directly on the ground, or will I need to put down a bed of crushed shell, gravel, etc.?

It would be best to put gravel underneath the shed. If you place your shed directly on the ground, it may not allow excess moisture to evaporate. Please give us a call at 855.853.8558 if you have any further questions. Have a great day!

I’m planning to build a 12X20 shed and want to just use AB3 gravel for the floor inside the shed. The frost line here is 36″ and I don’t want to have to pour a concrete foundation. The area is fairly level. I was thinking about doing this:
1. Set 4 CCA corner posts in concrete down to the frost line.
2. Dig about an 8-10 inch trench around the perimeter, between the posts.
3. Put about 6″ of leveled and tamped down AB3 gravel in the trench.
4. Lay out 6X6 CCA timbers (2 high, between the posts) and drill through with rebar for stability.
5. Backfill around the timbers with AB3, inside and out.
6. Build the shed walls on top of the timbers and attach to the corner posts.
Would this work?

I am considering purchasing a 16×24 Everest Tall Barn and using it as a workshop/additional living space to include a full bathroom. For this reason, I am planning to run utilities to the building including natural gas, water, sewer, etc. Since there is no way of knowing where the floor joists will be, there is no way to know where to locate the sewer line for proper flow (connection location) through a concrete slab. Therefore, I was hoping to have a standard footer with craw space installed and attached the Everest on top of it (just like a house). This way I could access the utilities by removing sections of the floor so I could run the sewer line (and other utilities) to exact areas of the building. Is it possible to have the building constructed/attached on top of this type of footer system?

so, i used crushed stone as a base for my foundation. and although i had it tamped down and leveled, i am still having an incredibly hard time getting my 4×4 PT ties level. there is always a few rocks jutting up and making things difficult. and that is just one. next i’ll have to level the others with the first. any suggestions?

also, for a 12×12 shed, lying on PT 2x4s (which will be on top of the PT railroad ties) how many 4×4’s would you suggest.

Posted on September 22, 2014 at 12:57 pm

Posted by bdeitsch

Hi Matt,
Thanks for visiting our blog. You could get away with two 4×4’s, but we would suggest three. One for each side plus one support down the center.

Our best suggestion for the leveling would be to use shims to help level it out. I added a link to our shed leveling document that shows this procedure. Hopefully this helps.

Have a great day!

Thank you for visiting our blog. When we install we put them on 4×4 treated runners. You can put pavers under the runners if you choose.

Good Afternoon,
I’m planning to build a 10′ deep,12′ wide, and 14′ high barn style shed. about 5′ of the width is a porch. I’m concerned about underground power and gas lines, so concrete anchors are worrying me. Would 4×4 runners on dek-blocks be sufficient as a foundation?

Posted on February 5, 2015 at 5:08 pm

Posted by bdeitsch

Good Morning Garrett,

This could work. This could be accomplished by using 4 rows (on the 12’ side) of 3 (on the 10’ side). You would want to make sure that one of the rows is where the shed turns into the porch (almost treating them as separate entities/structures) for proper support. Forgive the crude drawing.

Thank you for visiting our blog. We always recommend finding some way to allow air to flow under the shed. Especially if you live in an area that is humid and receives a lot of rainfall.

Good Morning Shelly,

There is no reason a foundation cannot be larger than a shed. Treated sill plates are required when installed on concrete. This keeps the siding above concrete which is required to avoid contacting concrete and degrading siding.

I am purchasing a 12×16 building, I understand that a concrete slab is recommended, my question is there is a small slab of concrete there already can this be used and add to it? And how thick should it be.

Posted on April 4, 2016 at 4:24 pm

Posted by bdeitsch

A concrete slab is one option to a foundation for your 12×16 shed. But this shed can also be built on a 2×4 treated floor frame (or larger floor frame) and OSB, plywood or other floor deck material. Constructing 16” on-center for joist spacing is the minimum recommended. Build at 12” on-center joists if for heavier use.

You could add a concrete slab next to an existing slab if you choose. A slab used for general use such as storage should be 4” thick. If for some reason you use the shed for a garage 4” thick should also be the minimum. But if a heavier vehicle like a truck the slab would be required to be thicker.

For concrete slab requirements always best to ask your local supplier for recommendations based on your intended use and any local code requirements.

Thank you for visiting our blog. Please let us know if you have any other questions!

Have a great day!

I really like the 16 x 16 Aspen and I’m currently installing my foundation and slab with a tentative purchase intent with your company. Our code here is, maximum of 256 sq. ft. shed without a permit. I’ve excavated -2′ around the perimeter and – 6″ for the pad. Right now I’m at that point of decision of concrete footer or not. I can fill my footer area with compacted 30D stone, then level the pad to grade or I could form and pour these footers which will cost a lot more bennies. I plan to frame the 16 x 16 pad for 6″ of concrete and call it a day. A few questions please; Will compacted stone under a concrete pad be sufficient for your shed? Can the shed be built without the floor in the quote if I have the concrete pad? What exact dims should that concrete pad be for your 16×16 Aspen? Thanks for your help, now back to work!

Good Afternoon Rg,

Thank you for visiting our blog. Yes, the 16×16 Aspen is a great choice as it offers lots of storage space and overall value. We would recommend footers that are slightly smaller than your typical one car garage. Considering ground movement, you definitely want that slab on a solid foundation to keep from cracking. Yes, the concrete pad can act as a floor with no wood floor needed, the bottom plate has to be a treated material. You’ll want anchor bolts placed in the concrete to place the treated plate to hold the shed to the concrete floor. THe shed is a true 16’x16′, so 192”x192″ are the dimensions. Great questions. Feel free to give us a call at 855.853.8558 if you have any other questions!

Have a great day!

Hi,
Looking at a 8×10 shed. Struggling with the foundation. Price is not important to me. One person told me crushed gravel would be fine, the other told me gravel would likely over time cause the doors to not close properly due to sinking.

Is concrete the only way to go? Or can crushed gravel be AS GOOD as concrete over time? Are there any reason to not go with concrete, other than price? Thank you!

Cheers,
Roger

Hi Roger,

Thank you for visiting our blog. Concrete isn’t the only method to give positive results over time for a foundation and doors working properly. Using gravel can have positive results over time compared to concrete. Make sure the gravel is packed down. And we recommend using solid masonry blocks on top of gravel with no more than 48” spacing between blocks. I hope that helps your project!

Hi, I’m building a 12×10 foundation for
A dog kennel. I wanted to know if using crushed asphalt would be a good ideal as a fill?

Posted on August 4, 2016 at 10:05 pm

Posted by bdeitsch

Good Morning Len,

Thank you for visiting our blog. Asphalt has no values worthy of anchoring a structure to since upheave on it can occur easily. I understand you are not anchoring to it but asphalt can get soft in extreme heat. Asphalt may compress unlike gravel, which once leveled, should remain solid for a shed foundation. Suggest you stay with proven fill under foundations such as a gravel intended for this use. Your local gravel supplier can recommend the size. I hope this helps answer your questions. Feel free to give us a call at 855.853.8558 if you have any other questions. Have a great day!

I’ve been looking at building a tiny house out of (2) 12×16 barn sheds I want to have the sheds install on top of a 2′ concrete foundation wall to allow a second story loft. I’m not sure if I need footings they will be at right angles to each other separated at the corners by 3 to 4 feet I could send you a floor plan of my design and see what you think

We recently removed our 12 x 10 shed due to opossums living underneath and mice making visits. We are looking at a 6 x 5 resin shed and we want it to be stable and eliminate any unwanted guests! Our plan is to have a concrete pad poured and we heard the pad should be the same size as the shed to keep water from gathering around the shed. Are we on the right track or do you have other ideas? Thanks!

Good Morning Herman,

Thank you for visiting our blog. Yes, you are on the right track for sure. A concrete pad would be perfect for a solid shed foundation and will keep the rodents we all love so much from getting in. Good luck!

Hi,

I found your blog and wanted to ask you for your opinion. I had a 10*12 shed installed. I was concerned about drainage so I had them build me a deck, using a 12 post with treated wood cemented into the ground, about 12 inches off the ground, and then a 10×12 shed on top of it. Have u heard anyone doing that ?

Posted on October 21, 2016 at 5:51 pm

Hi Anna,

Thank you for visiting our blog. The method of leveling above a wet area is a very good option in this case. Other than a deck, you have your shed on this is a typical method used when raising a shed foundation off the ground.

We even have some applications where we do exactly this type of post and concrete then attach the floor frame to the post.

As long as the deck is solid, supports your shed, no concerns here. It should a very reliable foundation method. Feel free to give us a call if you have any other questions. Have a great day!

I’m going to install a shed on an existing concrete patio which is quite old and uneven. The idea is to use concrete pavers bedded in mortar to level them. Does this make good sense? Thanks,
Neil

Good Morning Neil,

Concrete is a bit out of our area of expertise. Typically we recommend consumers get suggested concrete thickness or foundation specs from a local source (frost line, soil conditions, etc.).

Similar to my concerns are in these websites.

I just built a resin shed that will need a foundation 551/4″ x 271/2″.
With this smaller footprint, should I build a foundation with pea rock and concrete pavers?

What depth of rock?
Which type of concrete blocks? (What dimensions of concrete?)
Would 16″ square concrete pavestones (step stones) work?
Thanks

Going to build a 8×20 lean to shed will 4×4 skids under it on top of gravel be good for foundation?

Posted on December 22, 2016 at 9:27 pm

Posted by bdeitsch

Good Morning Scott,

The method you describe is perfect and one of our recommended methods for a shed foundation. Gravel allows leveling and water drainage. 4×4’s directly on the gravel are exactly what we’d specify for attaching your floor frame to. So, you are on the right track! Good luck!

I have a 20 x 30 Garage on skids. The main skids are running North to South. There is a 2 foot over hang on the East and West side which my walls are beginning to fall a little. I tried to place blocks underneath the garage on each corner and after 6 to 9 months the block is beginning to sink into the ground. I did not add gravel the first time. I want to do it right so I dont have to do it again. My plan is to take a small tiller and under each rafter that is running East to West to dig a hole about 8 to 10 inches wide and 12 inches deep 18 inches long and fill with gravel about 6 inches then use mason blocks or pour concrete 6 inches deep and then place 1/2 inch re-bar in an ” X ” position so that when the pressure is pushing down hopefully the re bar will help in keeping it from going downward along with the gravel helping too. I assume to do this about every 4 feet or so. Problem is I have to get the tiller close to the edge of my garage then dig til it get under the wood foundation then I can go under toward the skids. Please give me advice to learn the right way to build a foundation on a heavy Garage.

I have saved a 8’x 6′ shed from rotting any further. I managed to jack it up and move it with 4″ pvc pipe to a new location.
I jacked it up and sistered new 2×4 floor joist to the old badly rotted one and reframed them with new 2×6 around the exterior parimeter of the floor.
My next task is how to foundation this thing. It’s currently rested (unleveled) on 4×4 post which are on a fines mix (think clay sand) over about 3-4″ of recycled rushed/rolled concrete 1-1.5″ rock, which is pretty solid. My ideas are:
A. Adding two skids to rest it on the ground.
B. Jacking it up, resting the exterior joist on a row of leveled cinder blocks.
C. Resting the floor joist in 8 locations (4-corners, 2 in middle floor and 2 on center of longest exterior joist) on adjustable pier style blocks. This would allow me to adjust it level?

Thoughts?
Thank you for this amazing site! 🙂

Good Morning Griz,
You’re on the right track. The foundation option you described are similar to ours. Just be sure to level at each location for whatever method you choose. Download our shed foundation guide. Have a great day!

I am building a 20 a 20 foot floor for a workshop in a space under my house so the area is always dry. There is already a crushed stone floor. Can I dig a trench, fill it with stone and lay 4×4’s or 2×4’s on top of it for a foundation? If so, would they have to be pressure treated? Do I even need crushed stone if use pressure treated wood on top of dirt Would concrete blocks or pavers with 2×6 headers be a better idea? Which is the least expensive way to go?

Thank you very much,
Daniel

I am putting a small shed on artificial turf grass that was just installed. The grade is at a slight slope. I can’t dig through the new grass for piers or gravel. Any ideas on how i can level the shed foundation without penetrating the turf?

I am installing a 8×8 wood shed on an already existing concrete foundation (4 inches thick). So my foundation is bigger than the shed and it only is about an inch above ground, so I am going to cut it down to the 8×8 size. Is that want I should do?

Also what size anchors should I use and how long? My sill plate is going to be PT 2x4s.

Thanks for the advice.

Good Morning Jennifer,

Thank you for visiting our blog. You actually do not need to cut your concrete pad. The concrete pad can be larger than your shed.

Hi there I was wondering if you could help me and tell me how to insulate underneath a 9 by 16 shed that is sitting on cinder blocks on a concrete platform? It’s been there fore 16 years with no problems but now my shed floor on the inside is growing damp looking mold and everything in the shed smells musty. Thank you!

Great blog. I am installing a 16×12 shed on an existing 4 inch concrete slab. Is 4 inches considered thick enough? Since the slab is preexisting I was going to use the anchors that are epoxyed into holes drilled into the concrete. Good idea?

Hi there,
1. I am planning on getting a resin shed with an overall width of 7’3″ and an overall depth of 7’3″. How big does the concrete slab need to be?
2. When I dig I to the ground do I need to lay down some type of material first, then rocks, then the concrete or is this not right?
3. The weight of the shed is 351 pounds. Do I still need to have bolts installed in the concrete slab (not sure if I’m using the right words) around the perimeter to secure the shed that will be placed on top? If so how many and how far away from the edge of the slab
Thank you!
Rebecca

Good Afternoon Rebecca,

Thank you for visiting our blog. Hopefully this will help.

1. The concrete needs to be poured to at least the dimensions of your shed floor – 7’3” x 7’3”. The manufacturer would have specifics in their instruction for foundation size.
2. For under the concrete, only pea gravel is required. Concrete over the pea gravel.
3. Yes, it’s a good idea to use wedge anchors to secure the shed to the concrete slab. Even if 350+ lbs. the anchors assist for high winds. Please refer to the chart below for number of shed anchors and placement.

Hi, Much appreciate this website and all the info you have shared. I am putting in a Lifetime 8 ft. x 10 ft. Outdoor Storage Shed. I was thinking to build a wood base 9 x 10. Is it better to make teh base exact size or bit bigger or no difference.

I have removed teh grass, put rocks on teh base and going to use two 10 ft and nine 9 feet treated wood to make the base.

Thanks,
Irf
