In Marion County residential zones, all accessory structures combined may cover no more than 25 percent of the rear yard area, with fences in RS-zone uses excluded from that calculation (MCC 17.117.020).
Marion County limits how much of a rear yard can be filled with accessory buildings. MCC 17.117.020 states that lot coverage by all accessory structures, except fences in connection with uses in RS zones, shall not be more than 25 percent of the rear yard area. This keeps sheds, garages, and other outbuildings from overwhelming a residential lot. The regulation applies to all residential zones and to structures in other zones used in conjunction with residences, but not to properties in farm and forest zones (MCC 17.117.010). Minimum lot sizes are set separately by zone, for example two acres in the AR zone (MCC 17.128.070). Check your zone for its dimensional standards.
Adding accessory structures beyond the 25 percent rear-yard coverage cap is a zoning violation and can block permit approval until the excess is removed.
