Cal. Code Regs. tit. 25, § 11103 – Nonhousing Facilities.

(a) Housing developments may include such streets, sewers, utilities, site preparation, open space, and landscaping as the agency determines are necessary or appropriate in connection with the housing development.
(b) Housing developments may include other nonhousing facilities such as administrative, community, health, recreational, educational, commercial, dining, and childcare facilities. The agency shall exercise reasonable judgment in encouraging and approving applications for financing assistance for housing developments containing such nonhousing facilities, taking into account the following factors:
1. (1) Whether said facilities will directly benefit the occupants of the development,
2. (2) Whether said facilities will be compatible with a suitable living environment for the occupants,
3. (3) The nature of the intended occupants of the development, whether families with children, the elderly, the handicapped, or others,
4. (4) The views of local organizations and groups as to the needs of occupants and whether such facilities are or will be otherwise provided within the community for occupants of the housing development.
5. (5) The prior availability of such facilities in the community,
6. (6) The economic feasibility of including such facilities,
7. (7) The availability of and feasibility of using other sources of financing for such facilities,
8. (8) The availability of federal subsidies for housing developments containing such facilities.
(c) In reviewing the factors enumerated in (b) above, for the inclusion of nonhousing facilities within any request for a construction or mortgage loan commitment the agency shall be guided by the policies of:
1. (1) Encouraging common areas, play areas and childcare facilities in family housing developments, and congregate dining facilities in housing projects primarily for elderly persons;
2. (2) Requiring all such commercial facilities financed with a below-market-interest rate, to the extent of any benefit from such rate, to contribute to the support of the residential units in the housing development, and
3. (3) Avoiding duplication of services or functions existing within the community in areas convenient to the housing development which are provided at reasonable cost to the occupants of housing development.
