In the Rural Residential (RR) district, Ada County caps lot coverage at 10 percent for the base category and 20 percent for a rural residence. Building coverage is the total allowable percentage of a lot that may be covered by buildings.
Ada County Code Table 8-2-6-1 (Rural Residential, RR) sets a maximum lot coverage of ten percent (10%) for the base category and twenty percent (20%) for the rural-residence category. Title 8's Chapter 10 defines Building Coverage as 'the total allowable percentage of a lot that may be covered by a building or buildings.' Each base district (RP, RUT, R1, R2, and higher-density zones) lists its own maximum lot coverage in its Chapter 2 dimensional-standards table, generally increasing with allowed density. These coverage limits govern unincorporated Ada County land only.
Covering more of a lot than the district's maximum is a zoning violation; Development Services can deny permits or require removal of excess coverage.
