Do I need a permit for shed or accessory structure in Arvada?
It depends. Whether shed or accessory structure needs a permit in Arvada comes down to the details of your project.
Arvada generally requires a building permit for a detached accessory storage shed larger than 120 square feet, while a smaller shed usually does not need a building permit, so confirm the current size threshold with Arvada Building Services before you build. A building-permit exemption does not remove zoning: even a small shed must meet Arvada's setback and height standards, and detached accessory structures may sit as close as 5 feet to side and rear property lines in common residential zones, so check placement first. Adding electrical, heating, or plumbing to a shed requires the matching trade permits, applied for through the Arvada Permits (eTRAKiT) portal at arvadapermits.org. A shed that will have electricity, plumbing, or a permanent foundation falls outside the usual small accessory building exemption, which generally covers simple unpowered structures only. Electrical and plumbing work each normally require their own permit and inspection even when the structure itself would have been exempt, and many jurisdictions require a licensed electrician or plumber to pull them. Zoning setbacks, height limits, and lot coverage are reviewed separately from the building permit, so confirm placement with your local department before the shed is delivered or poured. 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.
