Missing Middle Housing: Seattle’s Path to a More Inclusive Future

As both an architect specializing in multigenerational housing and a housing advocate, I’ve seen firsthand how housing diversity can transform communities. Today, I want to talk about something close to my heart: missing middle housing in Seattle.

What is Missing Middle Housing?

Missing middle housing refers to those wonderful in-between housing types that bridge the gap between single-family homes and large apartment buildings. Think duplexes, triplexes, townhomes, cottage courts, and small apartment buildings that fit beautifully into neighborhood settings while housing more people.

Why Seattle Needs Missing Middle Housing

Seattle is at a critical moment in its housing journey.

1. Affordability Crisis: Many teachers, nurses, service workers, and other essential community members can’t afford to live in the neighborhoods they serve.
2. Limited Housing Options: Families, young professionals, and seniors have few choices between single-family homes and large apartment complexes.
3. Environmental Benefits: Compact housing near transit reduces car dependence and supports Seattle’s climate goals.
4. Community Vitality: More neighbors within walking distance helps support local businesses and create vibrant neighborhoods.

Recent Developments in Seattle

Seattle is currently considering important changes that would expand housing options. The City Council is reviewing adjustments to zoning as part of implementing House Bill 1110 and implementing the One Seattle Comprehensive Plan, which requires cities to allow more housing types in areas previously limited to single-family homes and ADUs.

In this proposed zoning, there are several key considerations, including:

• Allowing stacked flats (multiplexes) near transit without lot size minimums
• Increasing floor area ratios for multiplexes, especially stacked flats
• Eliminating parking mandates near transit
• Expanding affordable housing bonuses
• Retaining and expanding neighborhood centers

How You Can Make Your Voice Heard

If you believe, as I do, that Seattle needs more diverse housing options, here’s how you can engage with the City Council:

1. Attend Public Hearings: The next public hearing on this topic is scheduled for May 19, 2025. This is your chance to speak directly to council members.
2. Submit Written Comments: Can’t make the hearing? You can submit written comments to the City Council at council@seattle.gov. Make sure to reference CB 120969 in your email.
3. Contact Your Councilmember: Find your district and councilmember at seattle.gov/council and reach out directly.
4. Join Local Advocacy Groups: Organizations like the Complete Communities Coalition are doing great work to advocate for housing choices.

What to Say When You Reach Out

When contacting council members, consider sharing:

• Your personal housing story
• Why diverse housing options matter to you and your family
• Support for specific policy changes like allowing stacked flats throughout Seattle near transit without lot size minimums
• Your vision for vibrant, inclusive neighborhoods that welcome people of all income levels

The Future We Can Build Together

As someone who designs multigenerational housing, I’ve seen how different housing types can bring families and communities together. Imagine a Seattle with housing choices that allow seniors to age in place near family, young families can put down roots, and that provide affordable options for essential workers.

This isn’t just about buildings—it’s about creating a city where everyone belongs. Let’s make our voices heard and support a Seattle with room for all.
