California Code, Government Code - GOV § 7262.5

(a) The project is a “qualified affordable housing preservation project,” which means any complex of two or more units whose owners enter into a recorded regulatory agreement, having a term for the useful life of the project, with any entity for the provision of project rehabilitation financing.  For this purpose, the regulatory agreement shall require of the owner and all successors and assigns of the owner, as long as the regulatory agreement is in effect, that at least 49 percent of the tenants in the project have, at the time of the recordation of the regulatory agreement, incomes not in excess of 60 percent of the area median income, adjusted by household size, as determined by the appropriate agency of the state.  In addition, a project is a qualified affordable housing preservation project only if the beneficiary of the regulatory agreement elects this designation by so indicating on the regulatory agreement.

(b) The resident is offered the right to return to his or her original unit, or a comparable unit in the same complex if his or her original unit is not otherwise available due to the rehabilitation, with rent for the first 12 months subsequent to that return being the lower of the following:  up to 5 percent higher than the rent at the time of displacement;  or up to 30 percent of household income.

(c) The estimated time of displacement is reasonable, and the temporary unit is not unreasonably impacted by the effects of the construction, taking into consideration the ages and physical conditions of the members of the displaced household.

(d) All other financial benefits and services otherwise required under this chapter are provided to the residents temporarily displaced from their units, including relocation to a comparable replacement unit.  Residents shall be temporarily relocated to a unit within the same complex, or to a unit located reasonably near the complex if that unit is in a location generally not less desirable than the location of the displaced person's dwelling with respect to public utilities, services, and the displaced person's place of employment.
