The obvious question is what harm was done by putting it in the street?

If the building has 4 units or less and the landlord lives in one of the units.If the property is a SFH and the owner owns less than 3 SFH's.If the animal brings an undue financial hardship to the landlord.If the animal causes damages or harm to others in the building.

In California, the eviction process focuses heavily on the substance of the eviction paperwork.

Real risk of harm to others, not just defaulted rent and property damage.  

Pitbulls and other dangerous breeds will require risk insurance at a higher premium and will open you up to legal problems if the harms someone. 

There would be up to 7 women in the house as part of this program at any one time.The pros are 2 yr guaranteed rent from the company, not the individuals living there, a maintenance crew that works for the company and not out of my pocket, supporting a good cause.The cons as I see them, excessive wear and tear, possible issues with the neighbors, someone relapsing on my property and causing harm to the property and/or others.My question is first of all, does anyone have experience renting SFRs as group homes?

People like that also talk to neighbors and do harm in other ways.    

There is always greed, which is great in moderation, but again if you are happy with the tenant and the rent and you don't see any additional risk to your assets, whats the harm in having additional occupants.

I don't see any harm in using a laminate floor in all rooms.

Besides any attorney will tell you that talking to any law enforcement before you are required to with an attorney present can only do harm, it NEVER helps.Adam
