Summary

Whatcom County zones private, noncommercial boat docks by shoreline type: on a manmade canal built for boat traffic they are a flat-out permitted use in the Urban Residential district, but on natural shoreline they need either accessory-use status or, for lots abutting the open shoreline, a hearing-examiner conditional use permit under WCC § 20.20.150.

City-specific rules exist: Bellingham has its own boat dock permits rules that differ from Whatcom County's county-level regulations. If you live in Bellingham, check the city-specific page instead.

Private, noncommercial boat docks, launches, ramps, floats, moorages and boathouses pursuant to the Whatcom County Shoreline Management Program for owners of legal lots of record abutting the shoreline. The conditional use permit shall be approved if the hearing examiner finds that the proposal will not be hazardous or disturbing to neighbors and all applicable zoning requirements are satisfied. The criteria of WCC § 22.05.026 shall not apply.

Full Breakdown

Whatcom County's zoning code, not a standalone dock ordinance, controls whether a private dock gets built along the county's shoreline from Point Roberts to Lake Whatcom. 20 WCC, the Urban Residential district covering most shoreline subdivisions, splits boat docks into three tracks. 055) permits a private, noncommercial dock outright, no discretionary review, only when it sits on a manmade canal engineered for boat traffic under the Shoreline Management Program. 102) treats docks, launches, ramps, floats, moorages and boathouses as an accessory use where a residence already exists.

161) requires a conditional use permit for any private, noncommercial dock on natural shoreline, available only to owners of legal lots of record abutting the shoreline. 026, so a dock applicant skips that broader test. 32) district chapters, so the analysis does not change between a canal lot near Blaine and a Birch Bay or Lake Whatcom shoreline parcel. 16 WCC critical areas buffer.

Violations & Fines

A dock built without following the applicable track, canal-permitted, accessory, or hearing-examiner conditional use, is an unpermitted structure under Title 20 WCC and subject to code enforcement by Whatcom County Planning & Development Services, which can order removal or require an after-the-fact permit application. Because the hearing examiner's shoreline finding turns on disturbance to neighbors, a denied or contested permit may be appealed under the review procedures of Chapter 22.05 WCC.

Frequently Asked Questions

Do I need a permit for a boat dock on a manmade canal in Whatcom County?
No separate discretionary permit is required for zoning purposes: WCC § 20.20.050(.055) lists a private, noncommercial boat dock as a permitted use outright when it sits on a manmade canal designed for boat traffic under the Shoreline Management Program, though standard building and shoreline permits still apply before construction begins.
Who can get a conditional use permit for a dock on Whatcom County's natural shoreline?
Only owners of legal lots of record that abut the shoreline qualify under WCC § 20.20.150(.161). The hearing examiner must find the dock will not be hazardous or disturbing to neighbors and that it satisfies all applicable zoning requirements before approving the conditional use permit.
Does the county's general conditional use test apply to boat dock permits?
No. WCC § 20.20.150(.161) states that the criteria of WCC § 22.05.026, the county's standard conditional-use permit findings, do not apply to boat dock applications; the hearing examiner instead applies only the narrower hazard-and-disturbance standard written into that provision.
Can I add a dock to an existing waterfront home without extra permitting in Whatcom County?
Possibly. WCC § 20.20.100(.102) classifies private noncommercial boat docks, launches, ramps, floats, moorages and boathouses as an accessory use tied to the Shoreline Management Program, so an existing residential parcel may add one without the shoreline conditional use process required for vacant lots.
