Is an owner-occupied duplex rent stabilized?

[Elma Van der Ryst]

The owner (me) moved in after the tenant, if that makes any difference.

I don't necessarily want them out, but according to the lease I've inherited when I bought the duplex, they have a parking spot where I want to build a garage and an ADU. They can have a spot in the garage afterwards which will beat the snot out of parking in mother nature, but it'll take a few months to build during which they will have to park on the street. I'd like to know what I can and can't do. I know I can negotiate and I will, but I want to know what I can legally do in case that fails. Can I raise the rent with 50% because I live there, or can I improve my property as long as they get their amenity back when I'm done, perhaps?

Thanks in advance for any help.
