Please note that there is a typo in the current Guidelines. Section 4.10.3 should have said, “Accessory structures may not exceed 120 square feet; no one side dimension may be greater than 12 feet in width and 9 feet in height.” We apologize for any confusion. This will be corrected in a future update.
