The penalty for not doing so is at least $484 per day for each dwelling unit in violation.

Looking this up, I found that this zoning is indicative of single family dwelling.

Just like I think the majority of the human race are good people, most of my tenants are normal, reasonable, good people.In general, I don't think society thinks poorly of landlords and other REIs. 

I was about to start incurring $500 a month addiontal for a vacant dwelling policy.

The lawyer for our HOA had a different interpretation of a similar clause.Renting a property out for short term for somebody to sleep in and use as a temporary dwelling "probably" conforms to the usage of a property for residential purposes. 

I cannot assume what is in the mind of another human, but whatever his reasons are, he is doing a disservice to his client and therefore is not fulfilling his duties.

The MU-2 zoning requires one spot per dwelling unit. 

Some out of pure desperation, some out of lack of honor and human decency. 

So today I was doing maintenance at one of my rentals, I opened the closet to access the central AC handler unit to change the filter and after I opened the closet door,  I had to rearrange a few things to clear the space to the left so I can have a clear path to the filter slot.As I moved some clothes to the right my hand touched what appeared to be a human head on the rack.I quickly jumped back and in my mind was a scene in Silence of the Lambs...I tripped on myself and fell on my butt.I was so scared LOL.Glad the tenant wasn't there.

From experience with human beings, we always scout at least three other alternatives who can jump in and take over at any given time.
