12×18 Portable Buildings: FAQs
Do I need a Permit for a 12×18 Shed?
In most areas, you will need a permit to install a 12×18 shed since a 12×18 shed exceeds 120 square feet. However, it’s crucial to verify any specific regulations or requirements with your local permit office before buying a shed of any size.

How Much gravel do I need for a 12×18 Shed Foundation?
Establishing a foundation for 12×18 sheds typically means you’ll need around 3.5 cubic yards of gravel. We recommend extending the foundation’s dimensions by a foot on all sides compared to the shed’s size. Thus, you’ll need a pad measuring 14×20. We advise a depth of at least 4″.
Please note that these calculations will only work if your site is level. If you are installing your shed on a slope, more gravel will be required. For more site prep information, check out our site prep page.
How many square feet is a 12×18 shed?
The overall footprint of 12×18 sheds is 216 square feet. However, bear in mind that the usable interior space will be slightly less due to wall thickness.
To calculate the usable floor space, subtract roughly 5″ from each side of the interior dimensions. This accounts for wall studs (3.5″) and exterior sheathing and siding (up to 1.5″).
Hence, for the calculation, multiply 11 feet 7 inches by 17 feet 7 inches, yielding an estimated interior space of approximately 187.5 square feet.
