Across the United States, 500,000 individuals with autism are aging into adulthood. Today, children have a 1 in 36 chance of being diagnosed with autism. Sonoma is providing leadership in addressing the housing needs of this underserved population through its welcoming support of Sweetwater Spectrum, a model community for adults with autism and other related developmental disabilities.

A question universally on the minds of parents of children with autism is, “How will my child be cared for when I am no longer able?” Sweetwater Spectrum is working hard to provide a solution.

Sweetwater Spectrum is a nonprofit organization dedicated to exploring, building and evaluating an innovative housing model for adults with autism. It has developed and now manages a housing option in the Sonoma community utilizing supportive living services.  This model includes an enrichment program intended to foster both individual choice and community engagement to provide a “life with purpose”. We embrace residents on a wide range on the spectrum of autism and other developmental disabilities and support all financial capabilities.

Sonoma - Our First Campus

Sweetwater Spectrum’s pilot project is located in the city of Sonoma and opened in 2013.  The site is 2.79 acres and is located 4 blocks west of the city’s downtown plaza, encouraging local community integration.  The campus includes:

  • Four 4-bedroom homes for sixteen participants, with the ability for future expansion. In 2023 we finished our construction on a new home and increased our capacity to 20 residents. /li>
  • A community center – a single-level 2,300 square foot, common house – integrates a community space, kitchen, exercise studio, media room, and a library.
  • Our 1 acre organic farm has an energy-efficient greenhouse and provides opportunities for physical skill development and healthy eating. The greenhouse grows and distributes microgreens to  local and bay area restaurants year-round.  The farm also sells produce through on-site and local farmers markets.
  • An outdoor pool and 2 hot tubs.
  • Enrichment programs and opportunities are provided on site, and coordinated off-site. They are tailored to our residents’ individual needs, encouraging choice and community. Through personal choice, we foster a life with purpose for our residents.

Supported Living Model

The supported living model of Sweetwater Spectrum is based on co-housing, and offers choice to its residents with individual, customized and flexible programs, supporting life skills training, continuing education, gardening, art/music, exercise and healthy lifestyles.  The Sweetwater Spectrum site was designed to meet the specific needs of those with autism. The site was built to LEED gold specifications and is environmentally sustainable wherever possible. This includes solar panels, an energy efficient HVAC system and storm water management with bio swales.

Admission to Sweetwater

Since opening in 2013, Sweetwater was designed as a long-term home for our residents. While some turnover still occurs, in general openings are infrequent.

We do maintain and accept applications — when a spot becomes available, we look for the best fit for a new resident to join their existing roommates.

If your family has interest in applying, we suggest you start by viewing our virtual tour video and reviewing the information on our website.

Creating Housing

<!–Nationwide, there are few housing choices available for adults with autism or similar intellectual/developmental disabilities. Our model, with its first campus in Sonoma, uniquely encompasses a "life with purpose" for its residents and can provide a lifelong home.
