On October 1, 2019, I rented the back half of a rental in Phoenix, AZ. On first look, the unit was basically an Arizona room with one end walled off and then that split for a bedroom and future bath. What I thought was the owner, was the renter wanting to sub ease to help make his rent (this I found out after a couple of months) the bath was to be completed which it wasn’t. After a couple of weeks of nothing happening, I asked if he needed help. (I’m a retired general contractor in AZ). He agreed, he would buy the material, I would provide tools and labor to build the bath. I do a little demo work and ask about the material and he states he is a little tight on money, if I could pick it up this month, we would settle at next rent. So I buy lumber, plumbing parts, etc. Come the end of the month, he’ still broke, it carries over to next month and next. Finally, I confronted him on January 1 and he evicts me. Do I have any lien rights?
