AI Analysis
This bill expands a tax incentive program to encourage developers to convert underutilized commercial buildings or build new multifamily housing with at least 10% affordable units. Cities can offer a sales and use tax deferral, which is forgiven if the affordable housing is preserved for 10 years — otherwise, the taxes become due with interest. The program includes strict reporting, oversight, and a built-in review to determine if it’s working.
- Allows cities to offer a sales and use tax deferral for projects that convert underutilized commercial buildings or build new multifamily housing with at least 10% affordable units.
- Requires cities to hold a public hearing and adopt a resolution before launching the tax deferral program, and to outline application, approval, and appeal processes.
- Sets strict application requirements: applicants must prove the project would not happen without the tax incentive, commit to completing work within 3 years (extendable up to 24 months), and verify affordability commitments under oath.
- Mandates that projects be in areas zoned for residential or mixed use, not acquired by condemnation, and meet local planning rules — plus, for new construction, obtain a separate property tax exemption under RCW 84.14.021 and 84.14.020.
- If the affordable housing is maintained for at least 10 years, the deferred taxes are forgiven; otherwise, they become due with interest (but no penalties).
- Requires the Joint Legislative Audit and Review Committee (JLARC) to evaluate the program’s effectiveness by December 31, 2032, and mandates repeal if affordable housing units do not increase.
Who is affected
- Real estate developers and property owners — Developers or property owners who want to convert underutilized commercial buildings or build new multifamily housing projects may apply for a sales and use tax deferral, reducing upfront costs if they include affordable units.
- Low- and moderate-income households — Low- and moderate-income households benefit from increased availability of affordable rental or ownership units in urban areas where housing is scarce or expensive.
- Local city governments — Cities gain a tool to meet state housing goals and revitalize underused commercial zones, but must establish local processes to review and approve projects.
- Washington State Department of Revenue — The Washington State Department of Revenue must verify project eligibility, calculate deferred tax amounts, and collect deferred taxes if requirements are not met.
Pro/Con Analysis
Stronger case for benefits
Potential Benefits (5)
The program directly targets underutilized commercial zones and areas with insufficient housing to create new affordable units — a rare policy that leverages existing infrastructure and city planning goals to expand housing supply where demand is highest, especially for low-income households.
HousingPeopleRef: Sec. 1(1)-(2); Sec. 4(1)(a); Sec. 6(3)By requiring local zoning compatibility and linking to the existing property tax exemption program (RCW 84.14), the bill encourages mixed-use development and streamlines incentives for developers — potentially accelerating project approvals and reducing regulatory friction for affordable housing.
Business & EmploymentPeopleRef: Sec. 4(1)(a); Sec. 4(2); Sec. 4(5); Sec. 6(3)Cities gain flexible, locally administered tools to meet state housing goals — including the ability to set additional affordability conditions, extend timelines for good-faith delays, and establish appeal processes — empowering municipal planning autonomy without imposing top-down mandates.
Local GovernmentPeopleRef: Sec. 2(2)-(3); Sec. 4; Sec. 5(1)(e)-(f)The 10-year affordability lock-in and mandatory legislative review (by JLARC in 2032) with a built-in sunset clause creates accountability — if the program fails to increase affordable units, it automatically expires, preventing permanent revenue loss without measurable benefit.
FinancialPeopleRef: Sec. 6(4)(a)-(b); Sec. 6(5); Sec. 1(3)The requirement to verify affordability under oath and submit post-construction documentation creates a paper trail for enforcement — and the ability to deny deferral or require repayment if units aren’t delivered helps protect public investment from fraud or misrepresentation.

Potential Concerns (5)
The 10% affordable unit requirement is low and may not meaningfully increase *net* affordable housing — developers may simply reclassify market-rate units as affordable or include units that would have been built anyway, especially given the “but for” certification requirement that is difficult to verify rigorously. This risks inflating reported affordable units without increasing supply for low-income households.
HousingPeopleRef: Sec. 1(3); Sec. 5(1)(c); Sec. 5(3)(a)-(d)Cities bear significant administrative and oversight burdens — establishing public hearings, application review processes, and monitoring long-term affordability compliance — without guaranteed state funding to support these responsibilities, potentially diverting staff and resources from other housing or infrastructure priorities.
Local GovernmentPeopleRef: Sec. 5(3)(a)-(d); Sec. 5(6); Sec. 1(3)The 3-year construction deadline (extendable to 5 years) may incentivize rushed or substandard construction to meet timelines, especially if developers face pressure to lock in tax benefits — and while the bill mandates compliance with local codes, enforcement capacity may be limited in smaller municipalities.
Public SafetyLean peopleRef: Sec. 5(1)(c); Sec. 5(3)(c); Sec. 5(6)The tax deferral is only available to projects that prove they “would not have been built but for” the incentive — a high bar that may exclude many feasible developments, especially by smaller developers without deep capital reserves, thereby favoring well-resourced firms that can absorb tax costs and still proceed.
Business & EmploymentLean peopleRef: Sec. 5(6); Sec. 1(3); Sec. 6(4)(a)The deferred tax revenue is substantial — up to 10 years of sales/use taxes on construction materials and equipment — and while repayments are due if affordability isn’t maintained, the lack of penalties (only interest) and the non-dischargeable debt clause may reduce accountability for noncompliance, especially if developers go bankrupt or sell before the 10-year mark.

Who Is Most Affected
Developers with access to capital and existing commercial properties in eligible zones stand to benefit most — especially larger firms that can absorb upfront costs and navigate complex applications. Smaller developers may struggle with the 'but for' certification and 3-year deadline.
Low- and moderate-income households are the intended beneficiaries, but success depends on whether developers actually deliver units at or below 60% AMI — and whether units remain affordable for the full 10 years. Without rent stabilization or long-term enforcement, units may become market-rate after the lock-in period.
Cities gain a new tool to meet housing targets and revitalize commercial corridors, but must invest staff time and legal resources to administer the program — with no guarantee of state reimbursement. Smaller cities may lack capacity to launch programs.
The Department of Revenue gains new verification and collection responsibilities, but the fiscal impact is projected to be minimal due to limited project volume. The agency must balance oversight with administrative efficiency.
Existing property tax exemption programs (RCW 84.14) may see increased applications, but the叠加 affordability requirements could raise barriers for developers already struggling to qualify under the existing program — especially in high-cost areas where AMI thresholds are harder to meet.
