We had an engineer come out, and according to his opinion, the lots are not buildable.

I think I have the spot picked out, I am currently working with engineers, contractors and the county to get a better understand of the numbers it will take to make it happen. 

Depending on the lot if it is in the county's critical slope designation the foundation is required to be engineered.

They can do pretty much any type of inspection and have engineers on staff.

After that one meeting the engineered plan was recorded at the courthouse and we could sell individual units. 

Honestly, I still feel broke, My previous job 4-5 years back was 200kplus/yr (Subsea Engineer Offshore).

We will be looking into zoning, etc and consult engineers and architetcs to ensure it's a viable project in those other areas. 

An additional benefit of a detailed engineering-based Cost Segregation Study is that it can increase potential insurance premium savings as well as provides support for the property tax appeals process.

In speaking with the building department's engineer, they informed me that in the event that the ADU has a separate address, it requires separate meters from PG&E. 

I'm definitely new and I don't have all the logistics planned out this is just the vision now I'm trying to backwards engineer and figure out my steps I thought my first step would be to househack a 4-Plex on an FHA loan and then graduate to six or 12 units and then move on to bigger properties most likely outside of Chicago to your point. right now I am very confused this is the second time someone has said that four unit is not like a six or 12 but I'm not really sure in what ways is it the underwriting is it the management is it literally every aspect of it.
