Saggio Hills Breaks Ground in Sonoma County

Date Posted: 06.26.2025

Mithun joined with developers Freebird Development and Jamboree Housing, project team members and the community to celebrate the groundbreaking of the first phase of Saggio Hills, a 118-unit affordable housing community in Healdsburg, California.

The first phase of construction will deliver 48 affordable apartments, a 3,000-square-foot community center and new multiuse trails throughout the property that will improve access to adjacent open space. Residents and the broader neighborhood will also benefit from a range of concurrent transportation investments—including an expanded city bus route, a new zero emission bus, sidewalk improvements and new bus shelters along Healdsburg Avenue, and a multiuse trail extension that connects the site to Healdsburg Ave.

“This project is a key part of Healdsburg’s overall housing strategy for sustainable growth, aimed at providing affordable housing options for our local workers and neighbors and we’re excited to see it move forward,” said Mayor David Hagele.

The Saggio Hills housing community was designed to offer a variety of residential options: an elevator-served building provides a large number of accessible apartments; smaller walk-up buildings blend into the landscape and create smaller “neighborhoods” within the development; and ten affordable home-ownership duplexes that mimic the scale of adjacent single-family homes.

The project is a unique opportunity to create much-needed affordable housing in Sonoma County within a beautiful natural landscape. The design team brought an intentional approach to minimizing site disturbance, sensitively integrating the project into this oak meadow environment. Connection to nature and health promotion drove the integration of existing trails and connections to the adjacent Healdsburg Open Space Preserve. Stormwater management builds off historic drainage patterns and includes the restoration of Foss Creek’s riparian environment.

The project is targeting several sustainable metrics including EnergyStar Program and GreenPoint Rated Gold, and includes an innovative laundry-to-landscape greywater reuse system, extensive solar photovoltaics and EV charging stations.

Mithun’s Anne Torney, Lisa Jacks, Hilary Noll and Mohammad Momin join in celebrations.

The State of California’s Affordable Housing and Sustainable Communities (AHSC) program awarded the project $24 million in funding.
