COTS’ Shelter and Housing Programs

Housing Solutions for a Range of Needs

COTS understands the homelessness is a complex issue and that each person’s journey from homelessness to permanent housing is unique.  This is why COTS offers a wide variety of services to meet the needs of our clients.

Mary Isaak Center Shelter

Mary Isaak Center (Emergency shelter and central offices)
900 Hopper, Petaluma

The Mary Isaak Center Emergency Shelter is an 80-bed dorm-style shelter for individuals aged 18 and over. Dorm is sectioned by gender, with a special section dedicated to those who are maintaining sobriety. Case management, Client Enrichment, and Social Supports services are available onsite, as well as access to the Petaluma Health Center annex. The Emergency Shelter is run using a Harm Reduction model; substance use is tolerated but is not allowed on campus.

Recuperative Care

COTS six-bed Recuperative Care unit is a medical respite shelter program that offers a safe, clean environment to hospital patients who are ready to exit from the hospital but who do not have a home in which to heal. Services include healthcare coordination (i.e., scheduling doctor appointments, home health visits, and medical transport) and intensive case management to help clients become independent and “housing ready”. Clients must be age 18+ and have an acute medical condition from which they are recovering. Individuals are referred to Recuperative Care by the hospitals directly and can stay in the program for up to 90 days, at which time they generally transition to the main shelter to continue their journey to good health and housing.

Kids First Family Shelter (KFFS)

Kids First Family Shelter
1500 Petaluma Blvd S, Petaluma

Our Kids First Family Shelter offers shelter to families with minors. Case management and other supportive services are offered onsite.

Permanent Supportive Housing (PSH)

COTS has a number of permanent supportive housing options in the greater Sonoma County area including Petaluma, Rohnert Park, and Santa Rosa, CA. Our primary focus is for chronically homeless individuals, and unsheltered individuals with a high number of avoidable emergency room visits.

Clients work with experienced Care Managers to maintain housing, increase self-sufficiency, and improve well-being. We offer wraparound services including healthcare navigation services, job training and placement services, intensive case management, and behavioral health treatment options.

COTS employs a Property Manager to conduct quarterly housing inspections to ensure all clients maintain a safe and healthy environment, and to provide assistance with maintenance issues and requests to improve accessibility.

Integrity Housing

COTS’ Integrity Housing program master leases (or owns) multibedroom units throughout Sonoma County and subleases individual rooms to adults and families experiencing homelessness. The cost of renting a room in Integrity Housing is significantly lower than renting a market-rate unit, thus making housing more affordable to our clients. Case management, Social Supports, and other supportive services are offered to all clients. Some of our Integrity Housing units are specifically offered to those who are dedicated to maintaining sobriety. COTS’ Property Manager conducts quarterly housing inspections to ensure safe and healthy living environments for our clients.

Rapid Rehousing (RRH)

Rapid Rehousing assists individuals and families who are experiencing homelessness in obtaining and maintaining permanent housing by providing short-to-medium term financial assistance, case management, and other supportive services. Financial assistance is determined on a case-by-case basis dependent on client need. COTS does not own or manage the units that are rented by Rapid Rehousing clients, but we do enter into a financial agreement with property owners to pay security deposit and graduated rental assistance. We can also support clients with moving costs and utility assistance.

If you are homeless and seeking this type of assistance, please contact:

Rapid Rehousing Case Manager, Carmen Razo-Clark at 707.765.6530 x205 or [email protected].

If you are a property owner or manager and would like more information about partnering with COTS to offer housing to our clients, please contact:

Raija Freeman, Housing Services Manager, at [email protected] or 765-6530 x 201.
