Floating Residences
See also: Shoreline Master Program Code
Seattle's shoreline regulations limit residential uses on the water. In addition to liveaboards on conventional recreational vessels, the City recognizes four types of floating residences. These are:
- Floating homes
- Floating on-water residences (FOWRs)
- House barges
- Vessels containing dwelling units (VDUs)
City regulations specify how floating residences can be used and where they can be located. Many of Seattle's floating residences are uniquely constructed, and it may not be clear which of the above categories applies to a particular residence on the water. For questions regarding a specific floating residence or liveaboard craft, please contact SDCI. Have the verification or registration number ready so we can assist you.
As part of the Shoreline Master Program updates in 2015, owners of existing floating residences completed a one-time verification or registration process and were assigned a 3-digit number. Owners must keep their verification records current, which includes updating the City about any changes in ownership or location. Liveaboards on conventional recreational vessels (CRVs) as defined in the Shoreline Master Program are exempt from these requirements.
