Hassling Landlord!!!?

My landlord (actually his son-in-law, who now has “power of attorney”) is renovating the parking lot to better serve the business of the nail salon tenants downstairs and is telling me that I have too many vehicles out there. Right now, they are spread out at work and at my mothers, but cannot stay there much longer.

Does he have the right to do this? There is far more than enough room!

I was never told anything about any limitations or restrictions. In fact, there is NO lease or agreement… nothing signed.

What is the best possible action that I could take?
