Do I need a permit for shed or accessory structure in Unincorporated Delta County?
Unincorporated Delta County does not issue residential building permits.

Electrical and plumbing permits are issued by the State DORA Division of Professions and Occupations; electrical is under State Electrical Board inspection.
The requirements below come from Colorado rules and describe the standard the work must still meet. They are not a statement that Unincorporated Delta County will issue you a permit.
It depends. Whether shed or accessory structure needs a permit in Unincorporated Delta County comes down to the details of your project.
Colorado sets shed rules locally rather than through one statewide threshold, so the 200 square foot figure from the model International Residential Code does not govern here. Every Colorado jurisdiction we have checked uses 120 square feet instead: Aurora exempts a one-story detached shed or playhouse of 120 square feet or less, Arvada requires a permit above 120, and Wheat Ridge requires one above 120. In parts of Colorado a single regional building department serves a county and several cities at once, so confirm which office covers your address before you rely on any threshold. A building-permit exemption does not waive zoning setbacks or HOA rules, and running power to the shed still requires an electrical permit.
