A small tool shed is a good backyard storage solution. It solves a specific problem: too many tools and not enough yard space. Unlike larger structures, small tool sheds are typically suited for compact lots; they usually don’t require a permit in most cities, yet can accommodate the items needed in an average backyard. It is precisely these advantages that make them the top choice for homeowners with limited space or budgets.
This guide focuses on small sheds, typically ranging in size from 20 to 100 square feet. It covers actual size specifications, practical uses beyond storage, the debate between DIY and prefabricated sheds, and a complete step-by-step building process for small sheds.
What Size Is a Small Shed?
Small sheds typically range in size from 20 to 100 square feet. The most common sizes are 6x4 feet, 6x8 feet, 8x8 feet, and 8x10 feet.
- For very small backyards, a 6x4-foot (24 square feet) or 6x8-foot (48 square feet) shed is usually a practical choice.
- Homeowners with slightly more space typically opt for sheds ranging from 60 to 100 square feet.
The connection between size and permits is much closer than most people realize. Section R105.2 of the International Residential Code establishes a uniform national standard, stipulating that single-story, freestanding outbuildings with a floor area not exceeding 200 square feet do not require a building permit. Cities and counties typically establish stricter standards based on this.
- Los Angeles County stipulates in its building code that single-story sheds with a floor area of less than 120 square feet, a height not exceeding 12 feet, and an eave overhang of no more than 24 inches do not require a permit.
- Chicago allows shed-style structures of up to 150 square feet to be built without a permit, provided they are no taller than 15 feet and contain no plumbing.
- Toronto stipulates that single-story shed-style structures used solely for storage are limited to 15 square meters (approximately 161 square feet).
- Seattle’s regulations are stricter, with an exemption limit of 120 square feet.
Since most small sheds are significantly smaller than these four standards, it is common to build them without a permit. However, building setback and zoning regulations still apply, so it is still necessary to call your local building department before construction begins.
What People Actually Use a Small Shed For?
Storage remains the primary reason people build sheds. A small shed can typically hold gardening tools, a push mower, bicycles, hoses, and seasonal items without taking up space in the yard.
A second use has gained popularity rapidly in recent years: flexible living space. According to Extra Space Storage and the “Backyard Living” column in Homes & Gardens, homeowners are transforming small sheds into home offices, art studios, yoga rooms, reading nooks, and even guest rooms.
Who a Small Shed Actually Fits?
For urban and suburban homeowners with limited yard space, small sheds are the preferred choice, as a 4-by-6- or 6-by-8-foot shed fits where a 12x16 structure simply will not.
First-time homebuyers and renters on a tight budget also benefit greatly, as material and labor costs are proportional to the size of the shed.
Residents living in Homeowners’ Association (HOA) communities or cities with strict approval processes also tend to opt for small homes, as in Los Angeles, Seattle, and most other major cities, homes under 100 to 120 square feet qualify for exemptions.
Finally, enthusiasts who need a space for a specific purpose - such as gardening or bicycle storage - rarely require additional unused space.
DIY a shed or Prefab a shed?
Compared to personal preferences, cost and time more clearly distinguish these two approaches.
Cost.
The total cost of a small storage shed typically ranges from $800 to $2,300, with prefabricated plastic or metal kits usually costing around $500 to $750 before shipping.
In theory, the cost of DIY materials for a small storage shed falls within the same range, but if you purchase lumber, hardware, and the foundation as separate items, the cost can quickly add up. TERKKIN's full line of small kits ranges in price from roughly $510 to $2,200.
Time.
According to installation guides from several shed retailers, a small prefabricated kit can typically be assembled by two people in 4 to 8 hours.
Building a shed of the same size from lumber generally takes 12 to 40 hours; factoring in tasks such as cutting, planing, and surface treatment, the project often takes more than one weekend. For first-time builders, this time difference widens further, as varying levels of experience affect the time required for each step of the framing process.
- Who is DIY suitable for? DIY is suitable for people who already have basic woodworking tools, have a free weekend or two, and enjoy selecting each material themselves. It’s also suitable for those who need to build non-standard sizes or shapes (not included in kits).
- Advantages of DIY: You have complete control over the grade, layout, and dimensions of the lumber; you don’t have to rely on a single manufacturer’s parts list; and the cost per square foot is typically lower for larger projects.
- Disadvantages of DIY: If the design lacks engineering expertise, errors can easily occur during framing; the project takes several days and is subject to weather conditions; the total time required is several times that of using a prefabricated kit.
- Who is a prefabricated shed suitable for? Prefabricated sheds are suitable for those who are pressed for time, have limited construction experience, or have already decided on one of the standard sizes covered in this guide. They are also suitable for buyers who want to lock in a fixed price upfront rather than face uncertainty regarding material costs.
- Advantages of prefabricated sheds: Components arrive pre-cut and labeled, so assembly can typically be completed in a single day; the engineering design is handled by the manufacturer rather than being done on-site through trial and error.
- Disadvantages of prefabricated sheds: Material quality varies by brand, and some homeowners have reported missing parts or incomplete frames upon delivery; customization is limited to what is included in the kit.
How to Build a Small Shed, Step by Step
Plan the Shed First
Every construction project should begin with site selection, not with the lumber. Choose a location with good drainage, a sufficient distance from property lines, and enough space for the door to open.
Before beginning any excavation work, check the permit requirements, as specific limits vary by city. According to information on the above.
Regardless of size, setback and lot coverage regulations still apply. Drawing a sketch in advance that includes the door location and shelf layout can help avoid rework once you’ve started framing.
Build the Foundation
For a shed of this size, the foundation typically starts with corner support blocks rather than pouring concrete directly. According to a detailed guide from Home Depot, the standard procedure is to dig 5 to 6 inches deep at each corner, lay down crushed stone and tamp it down, and then place a concrete block on top and level it.
Mid-span supports, corner supports, and leveling with the ground are equally important.
Frame the Structure
The framing process follows a set sequence: first, install the floor joists; next, the wall studs; and finally, the roof trusses. Each component must be adjusted to ensure it is square before being permanently secured.
At this stage, precision is more important than speed. If a component is cut to the wrong length, it must be redone. A problem arose when a construction worker cut two identical support pieces to the wrong length; this minor measurement error forced the project to be redone.
A simple habit worth adopting is to mark each cutting line with a knife before sawing; this results in neater, more precise cuts than simply drawing lines with a pencil.
Add Doors and Windows
The door width should match the dimensions of the items that will actually be passed through it. For example, lawn mowers or wheelbarrows typically require a door width between 32 and 48 inches.
Weatherproofing the joints around doors and windows can prevent the most common complaint in tool shed reviews: water leaks.
Finish the Exterior
Exterior siding, roofing, and painting are the final stages of construction.
Finally, apply a coat of exterior wall paint or wood stain (which can be color-matched to coordinate with the home’s color scheme) to complete the overall look.
Organize the Interior
The interior layout should be designed based on the shed’s actual purpose. When used as a storage shed, it’s more practical to install vertical shelves and hanging rails along one wall, which frees up floor space for storing a lawn mower or bicycle.
When converting the shed into an office or workshop, however, it’s better to install a fixed workbench and enclosed storage cabinets.
Common Mistakes Real Builders Warn About
- A site inspection was omitted before beginning to erect the framework.
- Mid-span floor slab supports were omitted, which will cause the floor slab to sag over time.
- It was mistakenly believed that prefabricated kits were exempt from permit requirements—city and county building departments apply the same size restrictions to both prefabricated sheds and on-site-built sheds.
- The constructed area was smaller than what was actually needed.
A Closer Look at TERKKIN's Small Shed Kits
TERKKIN manufactures prefabricated storage sheds, with sizes specifically tailored to the small storage shed series covered in this guide, ranging from 6x4 feet to 8x10 feet; the larger single-slope roof models have maximum dimensions of approximately 12x7 feet. The panels are made of molded resin with a textured, wood-grain finish, rather than bare plastic siding, giving them a more attractive appearance.
The following four points make this product line ideal for buyers of small storage sheds as described in this guide.
- The size range is consistent with what was described earlier. The 6x4 and 6x6 kits range in size from 20 to 50 square feet; as previously noted, this range is best suited for the smallest backyards. The 8x6 and 8x10 gable-style models cover the 60- to 100-square-foot range, which most homeowners choose when they have a bit more space.
- The assembly process relies entirely on labeled parts. The kits come with illustrated instructions, pre-cut panels, and assembly hardware, making installation easy even for beginners. The product page also recommends that two people work together to complete the installation.
- Weather resistance is ensured by the materials themselves. Some reviewers have noted that the storage sheds have shown no signs of leaks even after withstanding several storms.
- Windows on the sides allow plenty of natural light to enter.
Final Thoughts
A small shed can solve a specific problem: too many belongings and not enough space to organize and store them. Its size, purpose, and whether to “build it yourself” or “buy a prefabricated unit” ultimately depend on several key factors mentioned in this article available space, budget, and the level of construction experience you feel confident in.
For readers who want to enjoy these benefits without having to build every frame from scratch, TERKKIN’s small shed kits offer a practical starting point.
