These things happen, the world is imperfect and the world if full of us things called human. 

I think behind tenant screenings and leases there is a quality of a landlord that's also as a person that is the respect for a good person and the intelligence of making fair affairs.For me for ten years in the past I had a house of 650sqft (two rooms and cozy kitchen) where I always have been giving away one of the room for others who were asking for help for themselves and I didn't had any earnings for me by that, and that has been during for many and many years, meanwhile I was surely needing more space for me, for my business in a studio and for my own personal life I eventually could have been having.Nonetheless this, on last years I had no more an house and I needed a room for rent, but even before any screening the landlords were being unrespectful and very unreasonably severe to me, they often had making me lose so much time by no taking or going away to the point I had no other choices in the end, and they set me in the wrong places for me, dangerous ones, too small, too big and very expensive, unhealthy ones or not providing anything at all when it was obvious they needed to.To me this kind of behaviour is very wrong, mostly because usually they are the same people who pretend respects and acts as they are very careful and attentive to housing situations in general, but with me, they have been lying above anything and just disrespected the person at a human level. 

I may have to get a variance for the existing dwelling unit's parking requirement, but I believe I meet all the SB-9 requirements.

(Note: I'm not a lawyer, but this is my understanding based on my experience)  A human being will need to sign on behalf of the LLC and that human will need to have the authority to sign. 

It counteracts human nature, which is laziness, greediness, self-centeredness.

Once you go through the whole process, you'll know exactly how it works in your area for the future.If the sweet nature of the dogs is what's bothering you, and how unfair it is that pit bulls as a rule are treated with what could be seen as deliberate malice by the media, give some money to the Humane Society to do more to advocate for the Cause.

From the fact sheet it's not clear to me if I would be able to evict both tenants or just one of them because it says you can take possession of only one dwelling unit and I am not sure if each of the studio rooms counts as a separate dwelling unit?

Unfortunately - there are a couple of issues here that likely make this hard to finance:-"Cabin style" dwellings typically are difficult to finance as the secondary capital markets treats these differently than standard single family homes as the buyer pool for a "cabin" dwelling is less than that of a standard home.- Yurts: Lenders typically have difficulty financing Yurts as they are moveable collateral.

for me I would have been better off donating that 75k to habitat for humans would have got more out of it than a tax write off !!

I wouldn't do pets with carpet but then again I don't do humans with carpet either.
