Middle Housing Update

City Council:

Council held a Public Hearing on middle housing amendments on July 11, 2023. Discussions with City Council regarding these updates will resume fall 2023.

On December 5, 2023, City Council adopted Ordinance 2407 which amends the text of the 2015 Imagine Bothell Comprehensive Plan to allow middle housing in all residential zones. These text amendments lay the foundation for future changes in the Bothell Municipal Code (BMC) to allow middle housing. The ordinance went into effect on December 13, 2023, and can be accessed here.

What is Middle Housing?

"Missing Middle Housing is a range of house-scale buildings with multiple units--compatible in scale and form with detached single-family homes--located in a walkable neighborhood." - Opticos Design

In this diagram from Opticos, you can see that there are many different types of Middle Housing options both in size and building type. The City of Bothell is specifically discussing duplexes, triplexes, fourplexes, cottage housing, and accessory dwelling units. Middle housing can be provided in a transitional zone between Single Family and Multi-family zones, or scattered throughout many traditional residential areas.

Housing-type definitions:

What do we mean when we say "house sized building" in neighborhoods with single family homes? Structures that have the same height and setback regulations as single-family homes.

What is an ADU? Accessory dwelling units, sometimes referred to as “granny flats” or “mother-in-law apartments,” are relatively small dwelling units that are accessory to a primary allowed use, like a single family home. Currently, ADUs are only allowed with single-family homes except in the Downtown Subarea, where they could also be accessory to a multifamily unit, like a townhome. Detached accessory dwelling units (DADUs) are sometimes referred to as “backyard cottages.”

What is a duplex? Structure with 2 independent dwelling units. These could be side by side, stacked, or front to back attached units.

What is a triplex? Structure with 3 independent dwelling units. These could be side by side, stacked, or front to back attached units. 

What is a fourplex? Structure with 4 independent dwelling units.  These could be side by side, stacked, or front to back attached units. 

What is cottage housing? These tend to be smaller scale, detached single family units, built around a shared common courtyard or outdoor space.

What are townhomes? Side by side attached units that often have multiple stories and individual entrances.
