Shed Permit Requirements: Do You Need a Permit?
Sheds are one of the most common unpermitted structures in American backyards — and one of the most common sources of code enforcement complaints. Whether you need a permit depends on the shed's size, height, foundation type, and your city's specific rules.
Size Thresholds That Trigger Permit Requirements
Most cities establish a size threshold below which a shed doesn't require a building permit. Common thresholds are 100, 120, 144, or 200 square feet of floor area. A 10×10 shed (100 sq ft) is exempt in many cities; a 12×16 shed (192 sq ft) usually requires a permit in those same cities.
Some cities use a simpler rule: any permanent structure requires a permit, regardless of size. Others base it on height rather than floor area. Always check your local rules before buying or placing a shed.
Setback Requirements for Sheds
Sheds are classified as accessory structures and typically have smaller setback requirements than your primary home. Rear setbacks of 3–5 feet are common. Side setbacks of 3–5 feet are typical. Some cities allow zero-setback for very small sheds (under 100 sq ft) placed in the rear yard.
Sheds generally cannot be placed in front yards or between the house and the street. They must also typically maintain at least 10 feet from the primary dwelling for fire separation.
Foundation and Permanence
Whether a shed is considered "permanent" often determines whether it needs a permit. Sheds on concrete foundations are always considered permanent. Sheds on piers, skids, or gravel pads may or may not be considered permanent depending on local interpretation.
If your shed is on a portable foundation (skids) and under the size threshold, it's exempt in most jurisdictions. However, even if a permit isn't required, setback requirements still apply.
Frequently Asked Questions
Do I need a permit for a prefab shed from Home Depot?
It depends on the size and your city's rules. Most prefab sheds are in the 100–200 sq ft range. If your city's threshold is 120 sq ft and the shed is 192 sq ft, you need a permit even though it's prefab. Check your city's accessory structure regulations.
How close to my fence can I put a shed?
Sheds typically need to be 3–5 feet from the property line (where the fence usually sits). Check your city's accessory structure setbacks. Note that the distance is from the property line, not the fence itself.
Can I put a shed in my front yard?
In most cities, no. Sheds and other accessory structures are typically prohibited in front yards. They must usually be placed behind the front building line or only in rear and side yards.
What if I already have an unpermitted shed?
You may be able to get a retroactive permit ("after-the-fact" permit) if the shed meets current codes. If it doesn't meet codes (wrong setback, too large), you may need to move or remove it. This situation most commonly surfaces during property sales.
