Full Breakdown
63(E) of the zoning chapter sets the size and placement rules for detached accessory structures on single-family lots. 63(E)(13); only one portable shed is allowed per property. A fixed shed or similar structure, including gazebos, greenhouses, and workshops, is capped at 200 square feet or 40 percent of the rear yard, whichever is less, but a fixed shed placed in a side yard instead is limited to 100 square feet and a maximum height of 9 feet. Detached garages get their own cap: 600 square feet or 40 percent of the rear yard, whichever is less, with a minimum width of 10 feet and a maximum depth of 25 feet, plus landscaping required around any exposed foundation of 30 inches or more.
No property may have more than one detached garage, and a property with a detached garage is limited to just one of a fixed shed, workshop, or greenhouse; without a garage, up to two of those three are allowed. Every detached accessory structure must sit at least 5 feet from an interior side lot line and a rear lot line, and at least 2 feet from the principal structure or any other accessory building, and none can exceed 15 feet in height or the height of the principal structure, whichever is lower. Fixed and portable sheds are barred from the required side yard and can't sit closer to the front lot line than the house itself.
Violations & Fines
An oversized or misplaced shed or accessory structure is a zoning violation enforced under § 10.99, the Code's general penalty, which carries a fine of $100 to $50,000 with each day the violation continues counted as a separate offense. Because portable sheds over 25 square feet and any fixed shed or detached garage require a building permit, erecting one without a permit can also trigger a stop-work order and removal requirement from the community development department.
