(c)
The department’s regulation shall permit alternative percentages of income for agency-assisted rental and cooperative housing developments pursuant to regulations adopted under subdivision (f) of Section 50462. The department shall, by regulation, adopt criteria defining and providing for determination of gross income, adjustments for family size appropriate to the unit, and rent for purposes of this section. These regulations may provide alternative criteria, where necessary, to be consistent with pertinent federal statutes and regulations governing federally assisted rental and cooperative housing. The agency may, by regulation, adopt alternative criteria, and pursuant to subdivision (f) of Section 50462, alternative percentages of income may be adopted for agency-assisted housing developments.
For purposes of this section, “area median income,” “adjustments for family size appropriate to the unit,” and “moderate-income household” shall have the same meaning as provided in Section 50052.5.
