Offsite Housing Action Plan

The Washington State Multi-Family Offsite Housing Action Plan provides a strategic framework for coordinating the production of homes in Washington to more fully realize the potential of offsite construction to lower construction costs and expand the housing supply.

In offsite construction, single-family or multifamily homes are fabricated in a factory and then completed onsite. When utilized effectively, offsite construction can achieve lower production costs through economies of scale and faster and more efficient home production. But this requires conditions that are not consistently available in Washington. This plan seeks to remedy this problem to more effectively achieve the cost savings and supply expansion of offsite construction.

To achieve this goal, the Plan identifies four connected priorities:

1. Build the evidence base and operating infrastructure needed to make offsite production understandable, measurable, and repeatable.
2. Align policy, regulation, and public capital to create predictable demand and remove barriers to industrialized housing.
3. Build manufacturing capacity, workforce capability, and an ecosystem of practice around the needs of offsite housing production.
4. Use coordinated pilot projects as a learning system that converts individual projects into a repeatable production pipeline.

These priorities are connected by design. Washington will not reach scale by solving permitting without financing, financing without demand, or manufacturing without projects. The work must operate as a system.
