Event part of MBAKS’ ongoing engagement on HB 1110 & HB 1337 implementation

MBAKS recently hosted a Middle Housing Forum focusing on state law changes now being implemented that could transform the housing landscape in our region and state.

The March 25 learn-at-lunch style event drew nearly 100 attendees. It was designed to help MBAKS members navigate the coming changes related to middle housing and accessory dwelling units (ADUs) following the adoption of HB 1110 and HB 1337 in 2023.

Panelists included Lilith Vespier, Infill Housing Manager with the Department of Commerce; Adam Weinstein, Director of Planning & Building for the City of Kirkland; and Ryan Gillis, Founder and CEO of Gillis Real Estate. 

In case you missed it, members can find a copy of the presenters’ PowerPoint slides on our Middle Housing & ADU Resources page, which is part of the Resource Library on MBAKS Connect.

Following panel presentations, attendees also heard brief updates from a handful of other city representatives in attendance from Bellevue, Bothell, Kent, and Lynnwood. Many cities in our two counties are in the process of updating local codes to comply with the new middle housing and ADU state laws. Local jurisdictions have until June 30, 2025 to update their codes.

The forum ended with audience Q&A time. During this open discussion, some members reiterated a point Ryan Gillis made during his presentation--the importance of flexibility in local codes so that builders can better respond to market demand. Another member stressed the importance of ensuring floor area ratios and building heights are properly set so that more project types are feasible to build. 

Members also expressed concerns about affordable housing fees that some jurisdictions are adopting alongside middle housing codes, as they will create unnecessary barriers to adding more housing choices.

MBAKS Executive Director Jerry Hall closed by sharing MBAKS’ overarching suggestion for cities implementing middle housing and ADU changes – “keep it simple.” The easier and more cost-effective it is to build middle housing, the more likely it is to be built, and the more attainable it will be for those looking for a place to call home.

Thanks to all who attended the Middle Housing Forum! To keep up with our advocacy work and changes related to middle housing and ADUs, MBAKS members are encouraged to engage with our Builders Councils.

The 2026 Washington State legislative session kicks off January 12, and it will be fast, fiscal, and highly consequential for housing. As a 60-day supplemental budget session, lawmakers enter Olympia facing mounting housing affordability pressures, limited time, and a constrained budget.

Governor Ferguson’s proposed 2026 supplemental budget aims to address an estimated $2.3 billion shortfall in the 2025-27 biennium. The proposal relies on spending reductions, tapping the state’s rainy-day reserve, and reallocating existing funds, rather than new taxes in the supplemental.

The shortfall reflects slower revenue growth, driven by weaker real estate activity and employment, alongside rising costs to maintain existing services. As a result, budget negotiations are expected to focus on fiscal prioritization and cost containment, with renewed discussion of potential revenue options. This includes proposals such as a payroll expense tax on large employers, changes to property tax growth limits, and renewed discussion of a high-income or “millionaire” tax as lawmakers weigh options to address the budget gap.

Despite these constraints, housing remains a top priority. Lawmakers broadly agree that we cannot address affordability without building more homes—but debate continues over how to do that.

Given budget realities, the most viable housing policies will be those that speed delivery, reduce risk, and avoid adding new costs. That is exactly where Master Builders Association of King and Snohomish Counties (MBAKS) is focused.

MBAKS 2026 Legislative Priorities: A Practical Path to More Homes

In 2026, MBAKS is advancing a focused, solutions-oriented agenda aimed at reducing delays, lowering costs, and expanding housing opportunities across Washington. Our priorities reflect what builders experience every day—and what moves the needle on affordability.

Subdivision Reform & Streamlining

Washington’s subdivision laws are outdated and unnecessarily complex. MBAKS supports modernizing subdivision statutes by clarifying pre-application requirements, requiring administrative approval of plats within urban growth areas, and encouraging concurrent review of plats and construction plans. These changes will shorten timelines, reduce risk, free up local staff capacity, and expand infill housing opportunities (HB 1818; SB 5633).

Clear & Objective Development Standards

Subjective regulations create uncertainty, delays, and higher costs. MBAKS supports legislation to ensure local development regulations are clear, objective, and predictable, leading to faster and more reliable permit approvals (SB 5613).

Self-Certification & Review Cycles

Redundant reviews drive up costs without improving outcomes. MBAKS supports allowing licensed professionals to self-certify code compliance and limiting projects to three review cycles when standards are met, preventing endless delays (SB 5729).

Building Code Pause

Constant code changes add cost and uncertainty. MBAKS supports rebalancing the Building Code Council’s membership and pausing frequent code updates to stabilize construction costs and improve affordability.

Rural Accessory Dwelling Units (ADUs)

Rural communities also need housing solutions. Streamlining Accessory Dwelling Units (ADU) permitting in rural areas can support multigenerational living, expand housing choices, and strengthen rural communities (HB 1010).

Oppose Increases to Fees, Taxes, & Housing Costs

At a time of record affordability challenges, Washington cannot tax or fee its way to more housing. MBAKS will oppose policies that increase housing costs through higher fees or taxes and continue advocating for solutions that make homeownership more attainable.

The Bottom Line

The 2026 session will test whether Washington is serious about addressing housing affordability. With limited time and tight budgets, success will hinge on cutting red tape, restoring predictability, and resisting policies that drive costs higher. MBAKS will remain at the table throughout session, advancing practical reforms that help builders deliver the homes Washington urgently needs.

Each election cycle, our Affordable Housing Council (AHC) interviews candidates at the city, county, and state levels to determine their degree of support for housing.

The following candidates have received the AHC endorsement for the 2024 General Election.
