Regional Affordable Housing Dashboard

Regional Affordable Housing Dashboard

An effort of the King County Affordable Housing Committee

Accessible metrics and performance measures are key tools for understanding King County’s housing affordability crisis and demonstrating the impact of solutions to address it.


Established by the King County Affordable Housing Committee, this website brings together multiple data sources for the first time to demonstrate the extent of the crisis, establish a baseline towards measuring progress to eliminate housing cost burden among King County’s low-income households by 2040, and provide downloadable resources for policymakers, planners, and researchers.

2023 Updates: : All sections of the Dashboard now use the most recent data available from the US Census, the Department of Housing and Urban Development, the King County Income-Restricted Housing Unit Database, and Puget Sound Regional Council’s Housing Incentives and Tools Survey. In some cases, data could not be updated, due to a lack of reliable or recent sources. For details on updates and data used, see the Data Notes, Glossary, and Methodology.

Key Housing Affordability Indicators

King County is in the midst of a sustained housing crisis.

In 2018, the Regional Affordable Housing Task Force (RAHTF) adopted a Five Year Action Plan to spur action to ensure all low-income households in King County have a safe and healthy home that costs less than 30% of their income by 2040. When households spend more than 30% of their income on housing, they are cost burdened and struggle to afford other necessities. Households are severely cost burdened when they pay more than 50% of their income on housing. Cost burden is only one measure for understanding affordability in King County. Explore the data below for a more complete picture of who is most affected and the remaining gap to meet the affordable housing need.

In 2021, 76% of low-income households in King County spent more than 30% of their income on housing.

Note: Area median income (AMI) is the household income for the median, or middle, household in a certain area. A household is a family or any group of people occupying a home.  The HUD area median family income (HAMFI) for King and Snohomish Counties in 2019 was $108,600 for a family of four. Housing and Urban Development (HUD) then takes this number and further segments incomes for different household sizes and uses these income limits to determine suitability for key housing programs. These benchmarks are then also used by other public housing programs. 

Regional Progress to Implement the Action Plan

To spur the County and cities into collective action to eliminate housing cost burden among low-income households by 2040, the Regional Affordable Housing Task Force adopted a Five Year Action Plan in December 2018. The plan calls for all levels of government and sectors to come together, scale up efforts, and implement new strategies to equitably address the crisis. The plan includes seven goals, with strategies to achieve the goals, and actions to implement the strategies. Explore this section to learn more about promising solutions and progress made to implement the Action Plan.

Measuring Impact

This dashboard can be used to assess the degree to which the collective actions taken to implement the Regional Affordable Housing Task Force’s 2018 recommendations are having their intended impact. Where year-over-year data is unavailable, baseline data is offered. In future years, progress will be measured against these baseline indicators and new indicators to more effectively measure the scale of impact and assess who is leading the way. This includes data to measure progress to increase regional collaboration (Goal 1) and better engage more stakeholders in addressing the need for more affordable housing solutions (Goal 7). 

Jurisdictional Housing Affordability Snapshots

Housing affordability conditions vary across jurisdictions in King County and so does progress to implement housing affordability solutions. Please note that the housing policy section does not show the extent to which a policy is implemented within a jurisdiction or how effective it is. It simply reports whether or not the policy is in effect somewhere within the jurisdiction. Explore these snapshots to learn more.
