Also, the building and permit department for the City is difficult to deal with.   

Based on the meeting we had this morning, I doubt if my department will exist much longer.

Call the state department of environmental quality (or who ever regulates commercial septic systems in your state) and see what they say.

its the act of marketing a home you do not own that violates state real estate laws.. at least in our state.so that is why in my response I told the guy you may want to check with your state real estate department..

Each bank has an REO  (Real Estate Owned) department.

@Michael Guzik - Talk to the police department especially if you are concerned with crime.

I can PM you my contact down at the housing department who will tell you everything you need to know from advertising your unit to completing the rent assistance inspection.   

Actually, if you are starting out and on a tight budget, it would not be unusual for you to handle the construction administration and project management during the construction phase and employ architect for plans, building department filings and design only.  

I'm currently looking at a property that would work if it had 2 units, and found this on the California Department of Housing's website "ADUs within existing structures must be allowed in all single family residential zones" This has really peaked my interest and I would love to hear what others might know.Thanks!

I deal with the Phoenix building department quite often, so feel free to PM me with any specifics.
