Cal. Health & Safety Code § 50650.4

(a) To be eligible to receive a grant or loan, local public agencies or nonprofit corporations shall demonstrate sufficient organizational stability and capacity to carry out the activity for which they are requesting funds, including, where applicable, the capacity to manage a portfolio of individual loans over an extended time period. Capacity may be demonstrated by substantial successful experience performing similar activities, or through other means acceptable to the department. In administering the CalHome program, the department may permit local agencies and nonprofit corporations to apply their own underwriting guidelines when evaluating CalHome rehabilitation loan applications, following prior review and approval of those guidelines by the department. The local agency or nonprofit corporation shall not subsequently alter its underwriting guidelines with respect to the use of CalHome funds without review and approval by the department, including how the local agencies and nonprofit corporations will ensure participation by low-income households if making loans in response to a disaster as described in paragraph (1) of subdivision (g) of Section 50650.3. In allocating funds, the department shall utilize a competitive application process, using weighted evaluation criteria, including, but not limited to, the extent that the program or project utilizes volunteer or self-help labor, trains youth and young adults in construction skills, creates balanced communities, involves community participation, or whether the program or project contributes toward community revitalization. To the extent feasible, the application process shall ensure a reasonable geographic distribution of funds.
(b) In administering department funds received pursuant to subdivision (a), local public agencies and nonprofit corporations shall not deny the funding application of, or apply different underwriting guidelines to, a housing program or project solely on the basis of either of the following:
1. (1) The home is a manufactured home or mobilehome, as defined in Sections 18007 and 18008.
2. (2) The home is located in a mobilehome park or in a manufactured housing community, as defined in Sections 18210.7 and 18214.
