York County, VA Building Setbacks & Zoning: Structure Height Limits (2026)

Sec. 24.1-230 applies each district's general height regulations to every principal and accessory structure unless another section of the zoning ordinance overrides it; the Airport Safety Management Overlay District's height cap under Sec. 24.1-371 can never be exceeded regardless of other exemptions. Sec. 24.1-231 lets the zoning administrator grant limited administrative bumps, such as up to 25 percent extra height (or 100 feet if free-standing) for spires, water towers, or antennas, and up to 8 feet for parapet walls, while the Board of Supervisors can authorize larger exemptions after a public hearing.

Sec. 24.1-233 sets separate standards once a single-family detached home's ridgeline or highest roof point exceeds 35 feet above average finished grade: exterior access to the roof and top occupied story must stay at or below 30 feet, and the building and site must be designed and maintained so ground or aerial ladder devices can reach the uppermost story or roof. Pushing the ridgeline past 40 feet is not an administrative matter at all; it requires the Board of Supervisors to approve a special exception through the same public hearing process used for special use permits, on top of continued compliance with the 30-foot access standard and a monitored fire detection and alarm system.

Sec. 24.1-232 layers on additional requirements for any building over 50 feet: accessible fire lanes around the entire structure and at least 40 feet of separation between any two buildings that tall. Sec. 24.1-233.1 allows a one-foot height bonus for every foot a home in the 100-year flood zone is elevated above base flood level, capped at 45 feet, with setbacks increased to match the added height.
