Ask tenant to move out for owner occupancy?

[Wenai Ji]

Hi all! 
I’m interested in buying a triplex to house hacking in Los Angeles. I have a question about tenant situation.

The triplex is consisted of 3/3, 4/2, 2/1. Currently 4/2 and 2/1 are tenant occupied. I plan to move in after purchase and live there as my primary residence.

My question is, is it a valid reason for me to ask the tenant in 2/1 to move out on the ground of owner needs to occupy the property? I live by myself, so it doesn’t make sense for me to live in the vacant unit in front that’s 3/3.

This tenant is currently on month to month, i believe she’s living there for more than one year. That’s all I could gather before my offer is accepted. 
Any guidance & advise is appreciated :)

Generally, if you intend to occupy the unit yourself, you may have grounds to ask the tenant in the 2/1 unit to vacate, especially if you plan to use it as your primary residence. However, specific regulations may apply, and it's advisable to consult with a legal expert or housing authority to ensure compliance and handle the situation appropriately.
