What Size Shed Needs a Permit in Denver
Whether you need a building permit for a shed in Denver usually comes down to size. In Denver, the cutoff is clear: detached sheds of 200 square feet or less don’t need a building permit, while anything larger does. A popular 10x12 shed (120 sq ft) comes in under the limit, so it typically doesn’t need a building permit. Larger sheds, and any shed with electrical, plumbing, or a permanent foundation, almost always need a permit regardless of footprint.
Building a Shed Without a Permit in Denver
Even when a shed is small enough to skip a building permit in Denver, “no permit” doesn’t mean “no rules.” A permit-exempt shed generally must stay at or under the 200-square-foot limit, sit on a non-permanent base (sheds on skids or a gravel pad are treated more leniently than those on a poured foundation), and have no electrical or plumbing run to it. Crucially, zoning setbacks still apply — your shed usually has to sit a minimum distance from property lines and other structures, and that holds even for a permit-free shed. Confirm both the size exemption and the setback distance with the Denver Community Planning and Development before you build.
