For example, barn shed footings would likely be required if the building contains a loft area or a second story. Additionally, the local government may require both a zoning and construction permit for accessory buildings of this size. Sheds over 10’ in height (or 12’ in some municipalities) often require footings of some type. If the shed includes a built-in floor, some municipalities allow them to be placed directly on a gravel pad. Sheds with walls under 10’ (or 12’ in some locales) may not require footings of any kind (although this is usually tied to a square footage requirement as well). Sheds are often divided by height as follows: Less than 10’ high Note that for these purposes, shed heights are typically measured at the wall (or “eave”) height rather than the height at the roof peak. Height is another significant factor as it helps to determine how much weight the shed footers will be supporting per square foot. Some locales make an exception to the footer depth requirement if the building is placed on a concrete slab. Larger sheds like these typically require “frost protection”, aka shed footings that extend below the local frost line. For example, 12×16 shed foundation footers may not be required, but some type of gravel shed foundation would likely be advisable. Sheds in this range often do not require “frost-proof” foundations but may be required to have a stone pad or shallow footers at 12” deep. (A shed foundation can still increase the longevity of a small shed you can read more about whether your shed needs a foundation here. Even if they do, any harm caused is likely to be insignificant. Very small sheds like these have a low risk of sinking or buckling. Sheds under 100 sq ft (or 200 sq ft in some locations) often require no footers whatsoever. Many local governments in our region divide sheds into the following size categories: Less than 100 square feet This may be the single most important shed footing factor.
In general, the consensus seems to be that “shed footing” is the proper term. Does a cement slab need footings for a shed?īefore we go further, what exactly do you call the frost-proof structures under a shed: “shed footings” or “shed footers”? This has been a topic of debate for years, and you may be more familiar with one of the terms depending on what area of the country you live in.How many footings do I need for a shed?.“Floating” Concrete Pad w/Shallow Footings
