Full Breakdown
Lane Code 16.290(7)(a) sets the RR property development standards. Structures other than a fence or sign must be located at least 20 feet from the right-of-way of a state road, county road or local access public road, and at least 10 feet from all other property lines. A structure under 120 square feet that is more than 10 feet from other structures may sit within the 10-foot setback. Lots under 1 acre created before March 30, 1984 use a reduced 5-foot side/rear setback. Along Class I streams, a 50-foot riparian setback applies. Farm (EFU) and Forest zones have their own, often larger, siting standards.
Violations & Fines
Structures built inside required setbacks without approval are code violations subject to Lane County Land Management enforcement and may require relocation or removal.
