Mark the four corners of the garden shed with wood stakes to give you an idea of where the shed will sit.
Do some research to find out if there are easements, setbacks, neighborhood restrictions or building permits that you need to deal with.
Contact the utilities and have your property flagged.
If the shed can be where you staked it out proceed to step 5. If not, relocate in an area that will work with property restrictions.
Remove the sod where the garden shed will sit and an additional 12 inches around the perimeter.
Level the pad with a carpenters level and a 2x4 piece of straight lumber.
Install four shed anchors at the four corners at a slight angle away from the shed.
Add 4 inches of gravel over landscape fabric and level.
