MDK Permitting › Permit guides
Do sheds and fences need a permit?
Small ones usually don't. Bigger sheds and taller fences usually do.
When does a shed need a permit?
A detached shed or shop over 200 sq ft usually needs a building permit. Smaller ones are usually exempt but still have to meet zoning setbacks, and electrical or plumbing in any shed needs its own permit.
When does a fence need a permit?
Fences up to 7 feet tall are usually exempt from a building permit. Taller fences usually need one. Some cities also have height limits near streets and corners.
What do you need from me?
Size or height, where it goes on the lot, and your address.
