Peoria, AZ Accessory Structures: Shed & Carport Rules (2026)

Section 21-315 of the Zoning Ordinance grades accessory building standards by size instead of applying one flat rule. A detached shed or accessory building under eight feet tall with a floor or projected roof area of 200 square feet or less can sit directly on the side or rear property line, as long as it has no utility service and stays screened from public view. Step up to eight or nine feet tall, or past 200 square feet, and the structure has to pull back a minimum of three feet from the side or rear line, still screened from view.

Past nine feet in height or 300 square feet in area, the shed loses those reduced setbacks entirely and has to meet the same setback the underlying zoning district requires of the house itself; a structure that size also has to conform to the City's Design Review Manual. Height is capped at twenty feet across most districts, rising to twenty-five feet only on lots zoned R1-18 or R1-35, or any district with an 18,000-square-foot minimum lot size. No accessory building can go in the front yard, and none can be built before the main house exists on the lot.

1, but it still has to meet the current building code and this Section's standards, and it can never be sold or conveyed separately from the primary dwelling.
