month to month lease renewal?

[Banu Sho]

I have two units Prop subject to RSO in LA County. The second unit occupied by family just became vacant due to death. The tenant of 1st unit wanted to rent the 2nd unit, filled out the application but I found a better tenant than him, so rented the 2nd unit to the other family.

The 1st unit tenant is very upset because he did not get the 2nd unit for rent. The 1st unit tenant is on a month-to-month tenancy but pays rent regularly. I would like to make a new lease with him so things are clear between both the tenants as they will be sharing the utilities 50% due to one meter only on the property.

His original lease is back from 2014 and then no lease contact thereafter. What is the notice time I need to give to the 1st tenant to make a new lease?

The 2014 lease had very little security deposit. Can I collect an additional security deposit to match with the current market, and for that what is the notice period?

When can I raise rent and how much can I raise? How much notice period to raise his rent?
