Defining Middle Housing

Middle Housing offers diverse housing solutions beyond single-family homes, including duplexes, triplexes, fourplexes, townhouses, stacked flats, courtyard apartments, and cottage housing. These types aim to increase density while maintaining compatibility with the existing neighborhood character.

Why is it Considered 'Missing'?

The "missing middle" highlights a significant gap in housing availability, specifically the lack of options between traditional single-family houses and large apartment complexes. Historically, zoning regulations have often favored single-family home development, making it challenging or impossible to build other types of housing. This has resulted in a shortage of medium-density housing, contributing to rising housing costs and limiting the variety of housing choices available to people.

Common Types of Middle Housing 

Early Adopters of the 2020 Kirkland Zoning Code Changes

In 2020, major amendments occurred to Kirkland's Chapter 113 zoning code, affording higher density allowances with cottage homes, carriage homes, ADUs (accessory dwelling units), and Two/Three unit homes. Understanding the need for more housing options, we launched our Urban Series comprised of cottage designs and DADUs (Detached Accessory Dwelling Units), featuring our signature Northwest Contemporary architecture. Our proven track record of over 30 completed Middle Housing projects, focused on enhancing density and housing diversity, makes Merit Homes a key resource for understanding HB 1110.

Staying Ahead of the Curve

Our Housing Crunch

Washington state is at the forefront of the "missing middle" housing conversation due to significant legislative actions aimed at addressing the state's housing crisis. Washington, like many other states, faces a severe housing shortage and rising housing costs. We need to build over 1 million new homes by 2044 to meet the growing population demand. 

Steps Washington State is Taking

Washington's House Bill 1110 (adopted in 2023) is a key driver. This legislation mandates that many cities in the state allow for a wider range of housing types in areas traditionally zoned for single-family homes. This law aims to increase housing density and affordability by promoting the development of "missing middle" housing, such as duplexes, triplexes, and townhouses. The "missing middle" approach is seen as a way to create more diverse and attainable housing options. 

Amendments Due by June 2025

The legislation effectively requires changes to local zoning ordinances, which have historically favored single-family detached homes. This shift in zoning policy is a significant step towards increasing housing supply. These local regulation adjustments must be implemented by June 30, 2025 (for select cities, including Bellevue, Redmond, and Kirkland).

Key Flexibilities to Watch For

State law establishes minimum unit allowances per lot, but local municipalities maintain discretionary control over development regulations to encourage Middle Housing growth. These areas of flexibility may include requirements for:
