In the RA Low Density Residential Zone, Knox County caps combined main and accessory building coverage at 30 percent of the lot area. Minimum lot area is 10,000 square feet on sewer or 20,000 square feet without sewer.
The Knox County Zoning Ordinance sets an explicit lot-coverage cap in the RA Low Density Residential Zone: Section 5.11.10 states main and accessory buildings shall cover not more than 30 percent of the lot area. Section 5.11.09 sets minimum lot areas of 10,000 square feet for a house served by sanitary sewer, 12,000 square feet where two dwelling units or a garage apartment share a sewered lot, and 20,000 square feet where not served by sewer, with greater area possible on health-department recommendation. Minimum lot width is 75 feet on sewer and 100 feet without. Coverage caps and minimum areas differ in other zoning districts, so confirm your zone.
Exceeding the coverage or minimum-area standard violates the Zoning Ordinance and carries a $10-$500 civil penalty under Section 6.20.02, with each day a separate offense.
