Bellevue City Council approves middle housing and ADU ordinances to meet state requirements

The Bellevue City Council convened on June 24, 2025, to discuss significant amendments to the land use code aimed at facilitating middle housing and accessory dwelling units (ADUs) in response to new state requirements. The meeting began with the city manager introducing the topic, emphasizing the importance of these changes to meet community housing needs and comply with state mandates.

The council had previously reviewed the proposed amendments on June 10, where they provided direction to staff on specific options to include in the final ordinance. The city manager noted that the proposed changes reflect a balance of community interests, acknowledging ongoing questions about implementation and monitoring.

Development Services Director Rebecca Horner presented the background of the project, which is part of a comprehensive plan update initiated by the council in February 2022. This update aims to address housing needs over a 20-year horizon, extending to 2044. The council's early actions included focusing on middle housing and ADUs, which became more urgent following the passage of state bills 1110 and 1337 in July 2023, mandating cities to accommodate these housing types.

Horner outlined the key components of the proposed ordinances, which include provisions for up to four units citywide by right, and six units near major transit stops or if two units are affordable. The amendments also introduce reduced parking requirements and establish guidelines for ADUs, allowing two units on all lots with specific size and height regulations.

The council discussed the implications of these changes, with members expressing their goals to increase housing affordability and accessibility while retaining neighborhood character. Some council members highlighted the need for larger cottage sizes and the potential for preapproved designs to streamline the process.

The meeting concluded with a call for action to adopt the final ordinances before the state deadline of June 30. The council's decision will shape Bellevue's housing landscape, aiming to create a more sustainable and equitable community while addressing the pressing demand for diverse housing options.
