What is an accessory building?

Any single story accessory structure which is 200 square feet or less, that does not contain electrical, plumbing or mechanical service does not require a building permit. Please note that even if your accessory structure does not require a building permit, it must still meet all applicable zoning standards (see height, size, and setback restrictions). Any electrical, plumbing, or mechanical work installed in an accessory structure requires a permit, regardless of size. 

Accessory structures may not be constructed unless there is a principle building (i.e. a house) being constructed or already established on the same parcel.

Accessory building classifications are as follows:

PERMANENT (buildings that have footings and a foundation, and are to be composed of steel, wood, vinyl, aluminum or cement fiber siding or other durable building materials as deemed appropriate by the building department official and the community development director. Any materials such as cloth, canvas and/or plastic shall not be permitted for permanent buildings).

SEMI-PERMANENT (buildings that are moveable (no footings or foundation) yet are composed of durable materials such as wood, steel, vinyl, aluminum or cement fiber siding. These buildings may be allowed indefinitely, however, shall require an accessory building permit with each new location on the lot or parcel).

To build an accessory building, you must submit a completed  permit application, including the subdivision, lot #, tax serial #. This information can be located at the Utah County website  (make sure to search the address numbers and city ONLY). Also make sure to include all contractors information and the project valuation. You will also need to include an accessory building checklist, a site plan, building plans and any additional required documents.
