Towing tenant’s vehicles?

[Kyle M.]

I have a 3 unit property that was being rehabbed and is ready to be stabilized (filled to full occupancy). I have one current set of tenants (whom I inherited from prior landlord- what a gift) that parks more cars in the parking lot than they are allowed per their lease. They also are illegally subletting or have just moved in a random person (over 18) whom is not listed on the lease. Am I allowed to tow the unlisted person’s car because they are not on the lease? Additionally can I tow them anyways because they are parking more than their allotted cars in the lot? This is an issue because as I move in the new tenants they will need those spots and I don’t want the good tenants I have screened to have to deal with these people.

This tenant has occupied the property for over 1 year so I sent them a notice to quit or vacate (within 30 days) for their violations- parking too many vehicles and subletting/unauthorized persons on October 31. I also sent them a 30 day notice of termination of their month to month lease that came over from the old landlord. Do I need to post towing signs on the property or can I just tow for the reasons stated above? Any advice or insight would be appreciated.
