Current Service Model 

Marin County’s Office of Emergency Management (OEM) is the lead agency monitoring life-threatening events, including extreme temperatures. OEM and the Public Health Officer monitor weather indicators using data from the National Weather Service and determine if activation criteria is met.  

A decision on whether or not to activate the shelter will be made by 12:00 p.m. for activation the following day.  In addition to sending an email to an extensive stakeholder list, we will post activation plans to this website and will also provide a recorded message at:  415-473-6100.  

Referrals for a placement at the severe weather emergency shelter will be made by Marin County homeless service provider partners:  

  • Homeward Bound
  • Downtown Streets Team  
  • Ritter Center 
  • St. Vincent de Paul Society of Marin 
  • Community Action Marin: CARE Teams  
  • Law enforcement and other first responders should coordinate with the above referral partners regarding bed availability daily. 

Transportation will be supported through bus vouchers and outreach staff.

This is a low-barrier shelter, meaning that anyone will be welcome to stay as long as they agree to be respectful of other shelter residents and staff and follow a behavioral code of conduct (e.g. one person per room, no illegal activity, etc.).

While many factors affect a person’s ability to remain stably housed—employment, physical health, substance use—these factors are all more effectively addressed when a person has a home. Learn more about Housing First in Marin County at
