Ten (10) percent of the total units of a housing development for transitional foster youth as defined in Section 66025.9 of the Education Code, disabled veterans, as defined in Section 18541 of the Government Code, or homeless persons, as defined in the federal McKinney-Vento Homeless Assistance Act (42 U.S.C. Sec. 11301 et seq.). The units described in this subparagraph shall be subject to a recorded affordability restriction of fifty-five (55) years and shall be provided at the same affordability level as very low-income units; or

(i)
All units in the student housing development will be used exclusively for undergraduate, graduate, or professional students enrolled full-time at an institution of higher education accredited by the Western Association of Schools and Colleges or the Accrediting Commission for Community and Junior Colleges. In order to be eligible under this subclause, the developer shall, as a condition of receiving a certificate of occupancy, provide evidence to the City that the developer has entered into an operating agreement or master lease with one (1) or more institutions of higher education for the institution or institutions to occupy all units of the student housing development with students from that institution or institutions. An operating agreement or master lease entered into pursuant to this subclause is not violated or breached if, in any subsequent year, there are not sufficient students enrolled in an institution of higher education to fill all units in the student housing development.
(ii)
The applicable twenty (20) percent units will be used for lower-income students.
(iii)
The rent provided in the applicable units of the development for lower income students shall be calculated at thirty (30) percent of sixty-five (65) percent of the area median income for a single-room occupancy unit type.

The development will provide priority for the applicable affordable units for lower income students experiencing homelessness. A homeless service provider, as defined in paragraph (3) of subdivision (e) of Section 103577 of the Health and Safety Code, or institution of higher education that has knowledge of a person's homeless status may verify a person's status as homeless for purposes of this subparagraph.

(7)
One hundred (100) percent of all units in the development, including total units and density bonus units, but exclusive of a manager's unit or units, are for lower-income households, as defined by Section 50079.5 of the Health and Safety Code, except that up to twenty (20) percent of the units in the development, including total units and density bonus units, may be for moderate-income households. For purposes of this subsection, "development" includes a shared housing building development.

This increase shall be in addition to any increase in density mandated by Section 9121(a), up to a maximum combined mandated density increase of thirty-five (35) percent if an applicant seeks both the increase required pursuant to this subsection and Section 9121(a). All density calculations resulting in fractional units shall be rounded up to the next whole number.
