Summary
In unincorporated Whatcom County, Title 20 zoning sets minimum yards from property lines. Rural Residential lots hold between 20 and 45 feet off the road depending on its classification, plus 5-foot side and rear yards. Bellingham, Lynden, and Ferndale write their own.
All structures, including accessory structures, shall be placed on their lots in compliance with the requirements of the setback table (subsection (5)(b) of this section), except as may otherwise be provided in this title.
Full Breakdown
For land outside a city, WCC 20.80.210 fixes setbacks off a table keyed to how the fronting road is classified. In the Rural Residential (RR) district a structure sits 45 feet back from a state highway or urban arterial, 35 feet from a collector, 25 feet from a local access street, and 20 feet from a minor access street, with 5-foot side and rear yards. Parcels inside the Lake Whatcom Watershed Overlay or Water Resources Protection Overlay tighten the front yard to 30 feet. A separate 10-foot open-space vista is required along the Canadian border, and waterfront lots follow the county Shoreline Management Program. Bellingham and the other cities apply their own Municipal Code standards.
Violations & Fines
Whatcom County Planning and Development Services enforces setbacks. Building into a required yard draws a correction order or stop-work notice; the cure is compliance or a variance through the hearing examiner.
