1. Do I need a permit?

A: In most local townships and municipalities, if a shed is less than 100sqft, you do not need a permit. For sheds more than 100sqft, it’s always best to go to your local town office and inquire about a building permit. 

2. How much it would cost me to build?

A: According to most building cost estimator programs, the average cost for materials to build a shed is about $22.85 per square foot. For example, an 8’x10’ shed equals 80sqft x $22.85 = $1,828.00.  

3. How much time will I need to build it?

A: The size of the shed plays a role in how long it will take to build it. An average 8’x10’ shed can be built in 3 to 4 days from start to finish.  

4. Do I need expensive tools or large equipment?

A: You do not need expensive tools, a typical miter and table saw will work just fine. You will also need basic hand tools, corded drill or cordless screw gun, standard 7 1/4’ skill saw, and a variety of garden tools for the foundation. 

5. Can I move my shed to another location?

A: You can move your shed to another location; however, a new foundation will need to be installed. Additionally, interior bracing, heavy-duty straps, and a small crane or front-end loader may be required to safely lift the structure to put it on a trailer or move it to another location on the property.
