Frequently asked questions
What size foundation does the Aoxun 12x20x9.3FT Metal Storage Shed Outdoor Large Garage Shed need?
A 12 x 20 ft shed sits best on a pad 1 ft larger on every side: 14 x 22 ft. At 4 in of compacted crushed stone that is about 5.9 tons; a 4 in concrete slab under the footprint takes 147 bags of 80 lb mix. Whatever base you choose, it must be flat and level, because resin and steel kits rack out of square on uneven ground and the doors stop closing.
Does the Aoxun 12x20x9.3FT Metal Storage Shed Outdoor Large Garage Shed need a permit?
At 240 sq ft it is over every common exemption, so plan on a permit. The IRC exempts one-story storage sheds up to 200 sq ft, but many towns lower that to 120 or 100 sq ft, and setbacks, HOA rules and electrical work apply regardless. Check your local code before ordering.
Is $1,399.99 a good price for this shed?
It works out to $5.83 per sq ft. Across the 69 steel kits we track, the middle 80 percent run $3.08 to $13.17 per sq ft with a median of $5.25, so this listing is above the $5.25 median. Amazon prices move often, and the same model in another color can list for a different price, so compare the variants below.
