Seattle Houseboat Buying Guide (Updated for spring 2024)

by Matt Goyer

Welcome to our 2024 Seattle houseboat buying guide! Written by Matt Goyer a houseboat agent and the owner and managing broker of the real estate brokerage Urban Living, this guide is based on his 10 years living on a floating home and his years helping many first-time houseboat buyers. We wrote it to give you an overview of what it takes to buy a houseboat on Lake Union. It will also give you a good sense of what it is like to work with us. Do you still have questions? Reach us at hello@lake-life-seattle.com.

What is a houseboat? What is a floating on water residence (FOWR)?

A houseboat is a floating structure used as a dwelling unit and moored in a rented or owned slip at a marina in the City of Seattle. Their technical term is a floating on water residence (FOWR). There are 215 FOWRs on Lake Union. Houseboats differ from floating homes in that houseboats are relatively easy to move between marinas and are not permanently connected to their docks with easily disconnected utilities. We also consider house barges to be houseboats.

What is a house barge?

A house barge is designed and used for navigation but lacks a means of self-propulsion and steering equipment or capability. There are 27 house barges on Lake Union.

Houseboat vs Floating home

What’s the difference between a houseboat and a floating home? See our helpful guide to the two types of on-water residences on Lake Union.

How big is a houseboat?

Most houseboats range in size from 150 to 1,000 square feet. However, there is an exception, the Aurora which is 4,800 square feet!

How much does a houseboat cost?

Houseboats can be as cheap as a $100k for a small fixer upper to $1m to a brand new 1,000 square foot one. However, there is an exception, the Aurora, which sold for $3.6m in 2022 but keep in mind, it is 4,800 square feet.

Can I get a mortgage for a houseboat purchase?

Yes! Though there’s really only one option for financing a houseboat purchase, Sound Community Bank.

Can I Airbnb or VRBO my houseboat?

No. Short term rentals (fewer than 30 consecutive nights) are not allowed for on-water residences of any type.

Can I move my houseboat?

Yes. Though finding a spot to move it to will not be easy and it may take years to find a suitable spot. Few things to keep in mind:

  • make sure the new location is compliant with City regulations for marinas with floating residences
  • notify SDCI
  • update your insurance and your lender
