State Specific Question About: CALIFORNIA (CA)

What rights do tenants have to record audio or video of their landlord or repair crews, in the home?

Do they have to notify about recording?

Deeper question-If the tenant is in their unit, along with an outside repair crew (hired by landlord), and the crew manager calls the landlord over speaker phone to include the tenant; AND the tenant just happens to have something recording the repair effort, which obviously then records that 3 way conversation; can the tenant then use that recording in a legal proceeding?

Lease terms give Landlord the right to record in all common areas of the building.

It also states common areas include living rooms and kitchens.

I agree this clears the landlord of any legal repercussions. But do these lease terms apply in a reverse manner?

Meaning because the landlord created a recorded space aspect and duly informed the tenants of the possibility of being recorded even in their kitchen or living room; can the tenant claim that means all parties have been fully informed and bypass privacy rights?
