question about owner move in eviction in California

[Gin Zhuang]

Hi everyone,

I have a quick question about how to the current sentence in CA rent control.

“NO-FAULT” JUST CAUSES

1. Intent by the owner or owner-relative to occupy the unit. This includes the owner’s spouse, domestic partner, children, grandchildren, parents, or grandparents only. For leases entered into on or after July 1 2020, the owner would only be permitted to occupy the unit, if the renter agrees in writing to the lease termination or the lease includes a provision providing for lease termination based on owner or owner-relative occupancy;

I am under contract with a duplex. I want to move into a unit. It is currently occupied by a family who has been living there since 2007. Their lease does not have a provision for lease termination. Could I remove them based on the above no fault just cause? What does the highlighted sentence mean?  Their old lease was signed in 2007. If I take over the property, does it mean that our lease is entered in 2021? Based on the bold sentence, I can not move them out unless they agree? Or even though I am the new owner, since the original lease started in 2007, I can still remove them based on owner move in? Any insight would be greatly appreciated!
