Sunnyvale City Council adopts new ADU regulations under updated zoning code

In the heart of Sunnyvale's city hall, a pivotal moment unfolded as the City Council convened on March 25, 2025, to address a pressing issue: the development of accessory dwelling units (ADUs). With the housing crisis looming large, council members gathered to discuss amendments to the municipal code aimed at simplifying the process for residents looking to build these units.

As the meeting progressed, Vice Mayor Selle took the lead, proposing a motion to introduce an ordinance that would amend Title 19 of the Sunnyvale Municipal Code concerning ADUs. This initiative, he argued, would not only streamline the community's understanding of ADUs but also align with the city’s broader housing goals. "Building an ADU is more accessible to our community members," he stated, highlighting the benefits of multi-generational living and rental opportunities.

Council Member Mellinger echoed this sentiment, emphasizing the importance of compliance with state law and the potential of ADUs to provide essential housing options. "ADUs are a great potential source for important missing middle housing," he remarked, appreciating the city's proactive approach to addressing the housing crisis.

The discussion also touched on the need for data to better understand the impact of ADUs once constructed. Council Member Cisneros expressed eagerness to explore findings from a recent Santa Clara County survey on ADU affordability and usage, indicating that this information could guide future policy decisions.

As the council members rallied behind the motion, the atmosphere was one of collaboration and determination. The ordinance was ultimately passed unanimously, with all seven members voting in favor. This decisive action marks a significant step forward in Sunnyvale's efforts to enhance housing accessibility and meet the needs of its growing population.

With the council's commitment to facilitating ADU development, residents can look forward to more housing options that not only address immediate needs but also foster community growth. As the meeting adjourned for a brief recess, the sense of accomplishment lingered in the air, signaling a hopeful future for Sunnyvale's housing landscape.
