Here is the REAL SOLUTION of affordable housing:

The State must create a database of ALL existing residential units that ACTUALLY EXIST! THIS IS MANDATORY TO ALL PROPERTIES!

Then they must create a database of all OWNED residential units that ACTUALLY EXIST! THIS IS MANDATORY TO ALL PROPERTIES!

Then they must create a database that accounts for all USED residential units that ACTUALLY EXIST! THIS IS MANDATORY TO ALL PROPERTIES!

Then they must create a database consisting of all UNUSED residential units that ACTUALLY EXIST! THIS IS MANDATORY TO ALL PROPERTIES!

OF COURSE the Housing industry will oppose this. Why?

This will provide the public the ACTUAL manipulated SHORTAGE of HOUSING in California.

Also there can be taxation designed so that for those properties NOT USED to be levied to fund public housing projects. This will be because the housing crisis allows for this extreme action as long as these units are not listed or used because it is against the state anti-trust and price manipulation laws.

It can be avoided if the properties are made available to the market.

But I will not be surprised that there is as much as an additional 10-15% of units just being withheld from USE because it makes other properties more valuable. And given Proposition 13, they pay pitiful property taxes on units that just sit and decompose due to intentional neglect. No upkeep means that the taxes are the only cost.
