Full Breakdown
2-218(1) in the zoning ordinance sets separate accessory-structure standards for each residential district. In the low-density Neighborhood Residential (NR) district, a shed, detached garage, or other accessory building cannot exceed 5 percent of the lot's total area, must sit behind the front façade of the principal house, and must keep at least a 10-foot side and rear yard setback (7 feet in General Residential, 5 feet in Urban Residential and Urban Residential-Mixed). Corner side yard setbacks for accessory structures range from 3 to 10 feet depending on the district and use type.
5 percent of lot size (whichever is greater) in UR and UR-M. Historic district lots follow a different rule: under Sec. 2-218 figures. New construction is reviewed for compliance through the same process as any Site Plan (Sec. 2-540) or Zoning Permit (Sec. 2-530) application. 00 fee, per the zoning fee schedule in Appendix A. Sheds proposed within a required front, side, or rear setback line, other than the narrow encroachments listed in Sec. 2-218(A)(5), are not permitted without that relief.
Violations & Fines
Building an oversized or misplaced shed without approval is a zoning violation enforced by the Zoning Administrator, who can require removal or relocation to bring the structure within the Table 40.2-218(1) limits. Owners who exceed the accessory-structure size cap or build inside a required setback must either modify the structure or obtain a $150.00 Board of Zoning Appeals variance before the structure can remain in place.
