Just purchased multi-family w/ tenant & want to move into one unit and eventually remodel...

[Brian L.]

The plan is to turn the present 4 small residential units into 2 larger ones. The 4 units are currently tenant occupied. Most of the tenants are month-to-month but the place is rent controlled. One of the tenant's is apparently in violation of his lease b/c 3 other people who aren't on the lease are living in the unit. What's the best procedure to get the ball rolling with my intended plans? Do I give notice to one of the tenants since I'm entitled to live in one of the units as owner-occupier? Thanks in advance for your help.
