In addition to the post office, check your local property tax office or Clerk of Court or public works/planning/building permit office. 

., no doubt @Richard Dunlop knows how to navigate the Detroit Courts better than I but one of the difficulties with getting judgments in Detroit is that the judges will not usually permit a landlord to get a money judgment at the same time as a possession judgment.

However, what I don't want is to recreate the same "problems" I have today. 

For the most part they are willing to work with you if you are proactive and file permits to correct the liens in a certain amount of time.What exactly is the lien for?

(Just a wild guess, but you're talking about 4400 sq. ft. of new construction here along with the land, permits, fees, and everything else that goes along with it).  

Again, with drought and watering restrictions in place, the tenant could be complying with the lease (to the extent permitted by law) and still the grass dies. 

Sam Leon my lease reads like this, paragraph 33, vehicle policy, "the tenant agrees never to park or store a motor home, camper, or any sort of recreational vehicle on the premesis and to park only "x" automobiles, license plate number "xxx-xxx" make of automobile, __________ only on the paved area provided in the designated and labeled parking spots.
