I'll try to collect and share theater info about their return to business as it becomes available. I've noted each of the theaters and will note their planned opening date and links to any additional information they provide.
Theaters are able to be open in all the counties I cover. 23 theaters are open - several are open weekends-only - many have reduced hours on weekdays.
One of the theaters that closed has been rescued. The former Sonoma Cinemas has become Prime Cinemas Sonoma. The new operators opened the theater on May 28.
For reference here's the State's Guidance (is guidance a requirement?) for Movie Theaters.
Industry Guidance: Movie Theaters and Family Entertainment Centers
The National Association of Theatre Owners and 310 companies representing over 30,000 screens nationwide have come together to commit to implementing expert-backed industry-specific health and safety protocols. Many of the North Bay theaters are included in that group. Click here to see the protocols and theater commitments
Some of the theaters have added reserved seating to ensure social distancing. You'd be wise to buy tickets in advance to ensure you're able to be seated if your local theater is open. Remember, while the State's guidance doesn't restrict seating in auditoriums, any county may be more restrictive.
