[Tenant US-CA] My studio (artist) keeps flooding. Is the LL required to do anything?

I'm in Los Angeles in a 1 story building that has ~12 artists' studios. Our building has repeatedly flooded during the rainy season this year and the last year and the LL refuses to do anything about it. I've had 1-4 inches of water in my whole studio space multiple times.

I understand what the protections would be if this was a residential space, but I'm not sure what I can do here. Is the LL required to make repairs to prevent the flooding, or pay for any services if the building is flooding (not just my studio, about half of the studios in the building and the common space are affected)? We are on month-to-month leases and I worry about retaliation if I attempt to push the LL on this
