Permit takeaway

Aurora's accessory structure application covers decks, porches, front stairs, gazebos, ramps, sheds, and patio coverings or pergolas, and the application itself does not authorize construction until the permit is approved.

Zoning and placement

Accessory structure applications collect square footage, peak height, deck height above grade, attachment to the primary structure, and whether the structure has conditioned space, exterior insulated walls, permanent windows or doors, electrical, heat, AC, or plumbing.

Building and trade review

Aurora notes that sheds are limited to 160 square feet under the accessory structure form, larger sheds need a different permit type, and residential accessory structures over 768 square feet require full frost-depth footings and foundation.

Call before applying when

Call before applying if the project is attached, has electric, plumbing, heat, AC, insulated walls, permanent windows or doors, is a shed over 160 square feet, or exceeds 768 square feet.
