Im a landlord in Mich & we own over 20 middle class houses & several High end rentals along with 2 self storage facilities, no landlord in his right mind is gonna bitch about a tenant doing improvements to a property , unless its building something like a wall , electrical & plumbing or landscape improvements are allways welcomed with us & i dont know any other landlords that are dicks when tenants do improvements.
I was also in construction 35 yrs , a contractor can file a lien against a property but its a meaningless peice of paper once the property owner shows he didnt consent or authorize any work , then it becomes a civil matter between the tenants & the contractor again where contractors have to sue tenants.
I never bothered putting liens on property because of how i arranged payment , 25% when materials are dropped on site , another 25% to 50% the day i start work , if its a 1 day job its 50% , then the remaining 25% when work is signed off on , i wouldnt pound a single nail for a property owner without atleast half the project in my pocket 1st , its a good way to get beat outta cash .
Your making it seem as if contractors are corrupt when most times its the property owner who stiffs the contractor after the work is done , there are unscrupulous property owners who know once a contractor attaches something to a bldg it cant be removed by the contractor for non payment so they have tons of repairs done , then screw the contractors knowing the lien only becomes active if they sell the property .
Puff n stuff aint out to fuk nobody over & he is operating within the law , btw i love the " Sleestacks " ssssssssss & they only come out at night .
