I do not worry much about "hurried or sloppy work" because it is also in my contract that all work must pass inspection, which may include the city / county (for permitted projects), lender and myself.

Most who get tripped up are those buying the smaller multi-families that don't possess the correct use permit/historical rental license activity. 

Insurance- coverage for new engineering, permitting, etc8.  

Also if this property is on septic that also can throw a wrench into the ability to call a space "a bedroom" as septic systems are sized and permitted based on the bedrooms.

we ran into this in FLA  a few years back when I had 4 starts and I exited that market.. permits  sub base all pretty tough for someone who is not there and already knows the systems hands down and has a devoted loyal sub base.. thats the key in my mind.

I am currently working on phase 2; building 2 ADUs.The permits are already in the works but the biggest question is what is the best approach when funding these 2 ADUs BEFORE I have the equity from my home?

Thank you  The good GCs charge 20% but this does not equate to your savings because the GC will have better contacts, have namer experience coordinating contractors, be more familiar with permit process and expectations of the inspectors.  

Specifically; rules, regulations and permitting procedure.

I'm attending local meetups too when my work schedule permits, but I want to do even more. 

I was just on their website looking at the permit process:CityofSac-STR PermitLooks like 90 days max until you get a conditional use permit but still reading as it seems a little unclear:A short-term vacation rental may operate from a location that is not the operator's primary residence for a total of 90 days in a calendar year.
