What's Required in Houston

What Size Shed Needs a Permit in Houston

Whether you need a building permit for a shed in Houston usually comes down to size. In Houston, the cutoff is clear: detached sheds of 120 square feet or less don’t need a building permit, while anything larger does. A popular 10x12 shed (120 sq ft) lands exactly on the limit — at that size it’s still exempt, but going any bigger triggers a 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 Houston

Even when a shed is small enough to skip a building permit in Houston, “no permit” doesn’t mean “no rules.” A permit-exempt shed generally must stay at or under the 120-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 Houston Permitting Center before you build.

Frequently Asked Questions

Yes, 120 sq ft is the maximum exempt size; any shed larger than that needs a permit.
The 2026 minimum building permit fee is $91.06 plus a $33.56 admin fee.
Yes, but if the slab is permanent, the structure is more likely to need a permit for foundation integrity.
In Houston, sheds of 120 square feet or less can be built without a building permit; anything larger needs one. The exemption usually also requires no permanent foundation and no electrical or plumbing, and zoning setbacks from property lines still apply even without a permit.
Often not, if it’s also within Houston’s 120 sq ft limit and has no utilities — many jurisdictions treat a shed on skids or a gravel pad as movable rather than a permanent building. A poured foundation or any electrical/plumbing typically triggers a permit. Confirm with the Houston Permitting Center; zoning setbacks apply either way.
