Good news for sellers: neither unincorporated Whatcom County nor the City of Bellingham requires a permit or registration for an occasional residential garage or yard sale. The rules you actually meet are about signage and not letting the sales turn your home into an ongoing store.
Washington cities and counties generally do not license household garage sales, and Whatcom County and Bellingham follow that pattern — no permit, no fee for an occasional sale of your own used goods. The activity is treated as accessory to normal residential use. Selling merchandise bought for resale, or holding sales continuously, can cross into an unpermitted home occupation or retail use that does trigger zoning review. Temporary signs are the common friction point: in Bellingham they fall under the sign code (BMC 20.12) and cannot be posted in the public right-of-way.
There is no penalty for lacking a permit, because none is required. Running sales at commercial scale can bring home-business or zoning enforcement, and signs placed in the right-of-way are removed.
