Houseboats in Seattle

Floating homes on Lake Union were occupied by fishermen, boatmakers, and others in the 1920s. In the 1930s, houseboats were cheap places to live for those living through the Depression. Slowly, the houseboat population changed to a more bohemian texture.

In the 1950s, over-the-water apartment buildings began to replace houseboats and their number dwindled. The City completed a Lake Union Sewer Line in 1965 and houseboat owners constructed sewer hookups and worked to extend docks. Architects took an interest in houseboats in the late 1960s, building them on a platform of cement and Styrofoam, not log rafts. Moorage rate hikes and evictions threatened houseboaters in the 1970s. Floating home owners worked to purchase their moorages in response.

Two strategies for dealing with this problem began to emerge: a campaign by houseboaters to buy their own docks and legislation to provide some curbs on the moorage owners' power. Seattle City Council passed an "Equity Ordinance" in 1977, providing strict controls on evictions and an attempt to hold moorage increases in check.

Moorage owners took the law to court and by 1983 the courts had sided with them, giving owners the right to change the use of their property. A new Equity Ordinance was passed in 1984, reducing the power of moorage owners to use their power of eviction. In 2010, the State asked the City to review the Shoreline Master Program, threatening the number of new houseboats that would be allowed.

This public hearing on July 6, 1977 took place during discussion of the revised equity ordinance and provides some understanding of life on a floating home.
