Spotsylvania County, VA Accessory Structures: Shed & Carport Rules (2026)

Sec. 2(2) limits every structure accessory to a single-family detached dwelling, including permitted extensions such as decks, to covering no more than thirty percent of the area within the minimum required rear yard for the lot's zoning district. Location is governed separately by Sec. 3. An accessory building attached to the house by a wall or roof is treated as part of the principal structure and must meet the full setback and height rules that apply to the house itself, not the more relaxed accessory rules.

For genuinely detached sheds, garages and similar structures, Sec. 3(7)(A) bars placement in any required front yard, and bars placement anywhere in the front yard at all unless the lot is at least two acres, or at least one acre in the residential resort (RR) or resort agricultural (RA) districts; only a statue, basketball standard or flagpole is exempt from that front-yard rule, and even those must stay at least fifteen feet from the front lot line and twelve feet from the side lot line.

In the rear and side yards, Sec. 3(7)(B) requires a residential accessory structure to stay at least ten feet from the rear and side lot lines, dropping to five feet in cluster subdivisions. Commercial and industrial accessory buildings instead follow the underlying district's principal-building setbacks, except that a commercial or industrial accessory structure of 250 square feet or less only needs a ten-foot rear yard. Anyone planning a shed larger than the county's building-permit threshold should also check with the Department of Code Compliance before starting a foundation or slab.
