What Shed Size Needs a Permit?

Having a shed on your property is great for extra storage or taking your DIY hobby out of the house. Depending on size, you may need a permit to build a shed.

U.S. laws and regulations dictate what can be built on a property, including sheds. In most cases, these regulations vary at the state level. If you are considering building a shed, keep reading to discover when you need a permit.

Why are Permits Necessary for Sheds?

Permits form part of zoning and building codes set out by local governments. These zones and codes regulate construction and land use. They are necessary because they ensure buildings are safe and follow legal guidelines. This also ensures that buildings do not create hazards.

If you need a permit for your shed, the rules state that it must be stable and not too close to other structures or property lines. You must comply with these rules, as does everyone else, to ensure your shed does not cause any nuisance.

When Do You Need a Permit for a Shed?

Generally speaking, a permit is required based on size, purpose, and location. Each area has its own rules, but there are some overall guidelines that apply to several areas in the U.S.

• Sheds smaller than 100 square feet: A shed under 100 square feet does not require a permit in many areas. This is because smaller sheds are considered minor structures with low risk.

However, even if no permit is required for your smaller-than-100-square-foot shed, you may still have to adhere to zoning rules. This means you will be restricted on where you can place the shed on your property. You must also keep it within the appropriate distance from property lines.

• Sheds between 100 and 200 square feet: This range often requires a permit but varies by location. Some municipalities consider sheds over 100 square feet as major structures. This is especially true if they include electricity, plumbing, or permanent foundations.

  In this case, a building permit may be needed to ensure the shed complies with safety codes and zoning laws.

• Sheds larger than 200 square feet: Large sheds are usually more than 200 square feet and typically require a permit. This is because large sheds are often permanent and have a bigger impact on surrounding structures and safety.

If you want to build a large shed on your property, you will likely need to include a foundation, which mandates a permit. Additional work like electrical wiring, plumbing, and insulation increases the need for inspection and permits.

Other Factors That Impact Permit Requirements

Shed size is a primary factor in determining whether you need a permit. But other factors also come into play. For instance, if you need a shed for storage only, you may not need a permit.

If you want to use the shed for function, such as an office or studio, you may need a permit.

As mentioned above, adding electricity or plumbing to a shed almost guarantees that you need a permit. Any building with water or a bathroom needs extensive permits because it is an inhabitable space.

The foundation you use for your shed will also impact whether you need a permit. Sheds built on concrete slabs or other permanent foundations need permits because they form part of the overall property.

If you build your shed on a compacted base or gravel, you may not need a permit. However, you must double-check this with your local municipality, as some areas view any foundation as a permanent addition.

Lastly, if your municipality has setback requirements, you must include the minimum distance between your shed and the property line. You may get a fine if you build too close to the line or another building. You will also have to move the shed.

Finding Permit Requirements In Your Area

Permit requirements vary widely across America, so you must check the location regulations before building your shed.

You can contact your local building or planning department for information. Or visit their website to get the information you need for your area.

This way, you can also avoid fines, penalties, and the forced removal of your shed.
