As affordability pressures persist across the region, Bellevue is exploring a plan to fast-track “middle housing” development by introducing a library of pre-approved home designs for detached accessory dwelling units (DADUs) and small homes.
Rather than hiring an architect and waiting months for design review, the proposal would allow builders to purchase a pre-approved design, submit it with a permit application, and receive approval significantly faster. The city is aiming to offer 10 different pre-approved designs, with a mix of “cottage” homes and DADUs up to 1,500 square feet.
The program builds on ordinances Bellevue adopted to expand the quantity and type of residential housing citywide. By increasing density and offering more housing types, the city can help long-term residents remain in their communities while creating more options for first-time buyers and downsizers.
Bellevue’s pre-approved library is intended to lower the cost and complexity of bringing smaller projects to market. City officials hope that faster permitting and reduced upfront expenses would encourage more builders to pursue these projects, potentially increasing the overall supply of homes and easing affordability concerns over time.
The approach has drawn recognition from the broader housing community. The Housing Development Consortium, a nonprofit focused on creating and preserving affordable housing, recently recognized Bellevue for its efforts to balance growth and affordability.
