Severe Weather Emergency Shelter (SWES)

Current Service Model 

Given the need to protect against the spread of COVID, it is not feasible to offer severe weather emergency shelter per our usual congregate model. Marin County will offer motel vouchers, services and meals at a single motel.As in previous years, activation will be triggered by weat her criteria identified by the Marin County Department of Health and Human Services (below).

Marin County’s Office of Emergency Services (OES) is the lead agency monitoring life-threatening events, including extreme temperatures. OES, the Public Health Officer, and the Medical Health Operational Area Coordinator (MHOAC) 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 3:00 p.m. for activation the following day.  In addition to sending an email to an extensive stakeholder list, we will also post activation plans to this website and will also provide a recorded message at:  415-473-6100.  The Homeless Outreach Coordinator will also send a group text message to the county’s outreach teams.

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
