Warming Centers

En español »

Warming centers are heated public facilities where you and your family can go for relief during periods of extreme cold. Sonoma County works closely with local homeless providers to ensure needs are being met and helps augment with additional resources as needed during freeze alerts. Where noted, these facilities and spaces are in addition to year-round shelters. The additional beds and spaces help protect people from the year’s harshest weather. Spaces may be available on a first-come, first-served basis, and may offer wraparound services as well.
