The above image is from Santa Cruz's 2002 application to the CDBG for $1M in federal funding to support implementation of their ADU Program. Passing the law is only the first step. Their plan included helping homeowners determine who is eligible, obtaining financing to build the ADU, matching homeowners with construction industry apprentices, assistance being new landlords (ie. what licenses to get, how to do a credit check), and also monitoring effectiveness of the program.
