Costco sells a wide range of outdoor storage sheds in resin, wood, and other weather-resistant materials. Current listings include compact sheds for patios and decks, medium models for lawn equipment, and large structures that can provide substantial storage or flexible backyard space. Costco groups its sheds into small models under 36 sq. ft., medium models from 37–100 sq. ft., and large models over 100 sq. ft.
Prices vary widely by size, material, brand, installation option, and promotion. The current selection includes models from Suncast, Lifetime, Keter, Yardline, Gorilla, and other brands.
What Costco Sheds Are Available?
Costco’s outdoor shed selection covers several sizes and uses. Smaller resin sheds are suited to tools, lawn equipment, bicycles, and other household items, while larger wood and resin structures offer much more floor space.
Some examples from the current listings include:
| Shed | Size | Material | Listed Price* |
|---|---|---|---|
| Suncast Modern Shed | 6′ x 5′ | Resin | $649.99 |

*Prices can change by promotion, availability, and location. The Costco listings supplied for this article show these prices at the time of review.
Costco also separates products into DIY assembly and installed options, so the advertised price does not always represent the same type of purchase.
Costco Storage Sheds Clearance and Current Deals
Costco regularly uses instant savings and Costco Direct promotions on selected sheds. These offers can change quickly, so a clearance or sale price should not be treated as a permanent price.
For example, the Suncast 6′ x 5′ Modern Shed currently has a listed price of $649.99 after $150 off in the supplied Costco selection. Costco also shows a Costco Direct promotion where buying multiple qualifying Costco Direct items can provide an additional $100–$400 savings. The specific promotion on the product page is dated and subject to availability.
Some larger sheds also show substantial reductions. The supplied listings include a Yardline Berkdale 14′ x 8′ model at $2,499.99 after $800 off. Costco’s product information identifies it as a large wood shed with 918 cubic feet of storage capacity.
Because Costco changes inventory and promotions, the best way to find a current clearance deal is to check the product page rather than relying on an older advertised price.
Costco Shed Prices: $399, $699, and $999
Costco sheds can fall into several price ranges depending on their size and construction.
A lower-priced shed may be a vertical or compact model designed for basic storage. For example, the supplied selection includes a Lifetime Vertical Storage Shed for $369.99, while a Keter Cortina Alto vertical shed is listed at $359.99.
Around the $699 range, shoppers can find larger compact sheds. The Suncast 6′ x 5′ Modern Shed is listed at $649.99 in the supplied selection.
For shoppers searching for a $999 Costco shed, the Keter DecoCoat 7′ x 7′ Premium Modern Outdoor Storage Shed is listed at $999.99.
These price points are useful for comparison, but they should not be considered fixed Costco price tiers. The exact model, promotion, delivery method, and availability matter more than the advertised price range.
When Do Costco Sheds Go on Sale?
Costco does not use one fixed annual date for shed sales. Discounts can appear as Instant Savings, Costco Direct Savings, or product-specific promotions.
The current Suncast 6′ x 5′ listing, for example, shows Costco Direct Savings with different discounts based on the number of qualifying Costco Direct items purchased. The offer shown on the Costco product page is valid through August 30, 2026, while supplies last.
For this reason, shoppers should check Costco’s shed category and individual product pages when planning a purchase. A product that is full price one week can later receive an instant discount, but there is no guarantee that a particular model will be marked down.
Costco Sheds 8 x 12 and Other Large Sizes
An 8′ x 12′ shed provides substantially more floor area than a small garden shed. Costco’s current selection includes the Lifetime Resin Outdoor 8′ x 12.5′ Storage Shed, listed at $1,599.99 in the supplied product information.
Larger models can be useful for:
- Lawn tractors and larger equipment
- Bikes and recreational equipment
- Seasonal household storage
- Gardening tools
- Work areas and hobbies
Costco classifies sheds greater than 100 square feet as large.
The Yardline Berkdale 14′ x 8′ is another example. Costco lists 918 cubic feet of storage, two doors, two shelves, four windows, a storage loft, and a floor kit.
Costco Sheds 10×20 and Larger Storage Options
A 10×20 shed provides about 200 square feet of floor area, making it considerably larger than the typical backyard storage shed.
Costco’s inventory can include large wood structures and installed shed options, but exact dimensions and availability change. The current catalog includes larger models such as the Yardline Upton 12′ x 20′ and 12′ x 24′ wood sheds, along with other large storage buildings.
For a shed of this size, buyers should check more than the listed price. Consider the foundation, site access, assembly or installation, local building requirements, drainage, and the space needed around the structure.
Costco Sheds vs. Home Depot Sheds
Costco and Home Depot both sell outdoor storage sheds, but the right choice depends on the individual model rather than the retailer alone.
Costco’s current selection includes resin and wood sheds, DIY kits, and some installed structures. Its shed category also includes small, medium, and large models.
When comparing a Costco shed with one from Home Depot, compare:
- Exterior and interior dimensions
- Storage capacity
- Material
- Roof design and load rating
- Door opening
- Windows and ventilation
- Floor system
- Assembly requirements
- Installation availability
- Delivery terms
- Warranty
- Current sale price
A lower purchase price does not necessarily mean a lower total cost if one option requires additional foundation work, assembly, or installation.
Do Costco Sheds Require a Foundation or Permit?
Some Costco sheds may require a suitable foundation, and local building rules can determine whether a permit is necessary.
Costco specifically warns purchasers of the Suncast 6′ x 5′ Modern Shed to check local city, municipal, and HOA requirements because the structure may require a permit.
Requirements vary by location and can depend on factors such as shed size, placement, zoning rules, property setbacks, and local building codes. Check with the appropriate local authority before ordering a large structure.
Are Costco Sheds Good Quality?
Costco offers sheds from established manufacturers such as Suncast, Lifetime, Keter, and Yardline, with different construction methods and materials. Quality therefore varies by model.
Resin sheds generally emphasize low maintenance and weather resistance. The Suncast 6′ x 5′ model, for example, uses multi-wall resin panels and all-weather construction.
Wood sheds can offer more traditional appearance and larger layouts, but they may require more site preparation and ongoing maintenance.
The best choice depends on how you plan to use the shed, how much space you have, and whether you want a DIY project or professional installation.
Costco Sheds FAQs
Are Costco sheds good quality?
They can be a good option, but quality depends on the specific brand, material, size, and construction. Costco carries resin and wood models from several manufacturers, so compare specifications rather than judging every shed the same way.
How much does a Costco shed cost?
Prices vary from compact models costing a few hundred dollars to large wood or installed structures costing several thousand dollars. Current listings supplied for this article range from about $360 to more than $9,000 depending on the model and installation option.
Is it cheaper to buy a shed or build one?
Buying a ready-to-assemble shed can reduce design and construction work, while building one yourself may offer more control over dimensions and materials. Compare the complete cost, including foundation materials, tools, labor, permits, and finishing.
Do Costco sheds require a foundation?
The requirements depend on the shed and local rules. Check the manufacturer’s installation instructions and your local building or zoning requirements before installation.
Conclusion
Costco sheds range from compact resin storage units to large wood buildings and installed backyard structures. The current selection includes small, medium, and large models, with prices and promotions changing by product and availability.
Before buying, compare the shed’s dimensions, material, storage capacity, delivery, assembly, foundation requirements, and local permit rules. Checking the current Costco product page is also important because sale prices and inventory can change.
