Coronavirus (COVID-19) Affects the Ballet World in COVID-19: Ballet and the Arts Posted October 1, 2020 I mentioned living in a densely populated county because it means there are a lot of ballet studios in my area. California has very strict reopening guidelines right now. Yesterday the Bay Area moved into the next tier, which means ballet classes can have 25% capacity now. (Room capacity, not 25% of normal class size). Unfortunately where I live the county refers complaints to the cities and the cities turn a blind eye or suggest contacting OSHA.
