Full Breakdown
Roanoke County's zoning ordinance fixes yard setbacks district by district inside each zone's Site Development Regulations, Sec. 30-41-3. In the R-1 Low Density Residential District, subsection (B) sets the front yard at 30 feet for principal structures, with accessory structures required to sit behind the front building line rather than meeting a fixed distance. Side yards run 10 feet for principal structures; accessory structures must sit either 10 feet behind the front building line or 3 feet behind the rear building line. The rear yard is 25 feet for principal structures and just 3 feet for accessory structures such as sheds and detached garages.
Corner lots and other parcels fronting more than one street do not get a break: § 30-41-3(B)(4) applies the front setback to every street frontage, not just one. These figures are specific to R-1; the county's other residential districts, R-2, R-3, R-4, the Planned Residential Development district and the agricultural AG-3, AG-1 and AR districts, each carry their own numbered (B) subsection in their Site Development Regulations with different front, side and rear figures, so a lot's actual zoning classification controls which numbers apply. The Zoning Administrator, part of Roanoke County Community Development, confirms setback compliance when issuing a zoning permit under Sec.
30-9 and again at building permit review, and a survey or plot plan showing the proposed structure's distance from each lot line is standard practice before submitting. A homeowner who cannot meet a setback, for example building a garage closer than the accessory-structure minimum, must apply to the Board of Zoning Appeals under Sec. 30-24 for a variance rather than build first and ask later.
Violations & Fines
Building within a required setback without a variance is a zoning violation the Zoning Administrator enforces under Sec. 30-21, and it can require the structure be relocated, altered or removed at the owner's expense. The county's general zoning penalty in Sec. 30-22 applies to continued noncompliance. A variance from the Board of Zoning Appeals under Sec. 30-24 is the only way to build closer to a lot line than these minimums allow.
