Cal. Health & Safety Code § 50738

The department may make payments pursuant to Article 2 (commencing with Section 50745), 3 (commencing with Section 50755), or 4 (commencing with Section 50765) or contract to make annuity fund payments, or both, only if such payments or trust fund assistance result in affordable rents in assisted units for eligible households. The payments may be provided as loans to be repaid and payments of principal or interest may be deferred or made payable over a period of time. The payments may also be provided to acquire rights of occupancy or leaseholds, or to write down the development costs of a rental housing development. In addition to making payments to provide assisted units for eligible households, the department may provide funds if necessary to ensure the economic feasibility of, and to enable the construction of, rental housing developments assisted under this chapter, but no more than 10 percent of the moneys appropriated to the Rental Housing Construction Fund may be used for this purpose.
