Full Breakdown
Under the Unified Development Code, sheds and other accessory buildings can't be permitted until a principal building already stands on the lot. Small sheds get a break on placement: any accessory building under 200 square feet may sit right on the side or rear property line with a 0-foot setback, while larger ones owe the standard setback. No more than two accessory buildings are allowed per lot, their combined footprint can't exceed 15% of the property or be larger than the house's own footprint, and none may encroach on a recorded easement. Bigger or additional structures need a conditional use approval.
Violations & Fines
Building a shed before the house exists, exceeding two accessory buildings, blowing past the 15% lot-coverage cap, or building over an easement can draw a stop-work order and require removal, relocation, or a conditional use application before Planning approves it.
