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.
All the counties I cover are in the "Orange Tier" now. Movie theaters can reopen to 25% capacity once again, and Marin has removed the restriction on concession sales - reverting to the State's guidance. 13 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 is becoming Prime Cinemas Sonoma this summer. The new operators are working on getting the theater ready for reopening.
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
Don't even think about attending a theater if you aren't wearing a mask.
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, the State's guidance allows only 25% of the seats (up to 100) in any auditorium, and a county may be even more restrictive.
