Here is a list of why adding a single ADU in single family zoned areas in my CA market is typically a poor RE investment:1) The value added by the ADU addition is often significantly less than the cost of adding the ADU.

Account ClosedAdding your property manager as "additional insured" is standard practice and beneficial for you.

Duplex have different zoning that may permit additional units.

My goal is to leverage that equity for additional income.

Additionally, I would like to attempt to do the process Owner/Builder with subcontracting work out as well as doing some of the work I'm comfortable with (I have some experience with bathroom & kitchen remodeling an am not new to the construction industry).

Ok it might not be 1:1 but it will add additional revenue.

Also know that building a home seldom goes as expected - I have relatives that just built a nicer house… they thought it would take 9 months… it literally took 18-24 months between delays in permitting and the builder just not being able to get it done in a timely manner - often due to sub-contractor issues.  

The landlord should be named on the tenant's insurance policy for additional protection and to assist with tracking compliance.

People seldom look at actual crime numbers.  

I am considering building up on my fourplex. 2 additional units.
