Cal. Health & Safety Code § 50710.1
(c) A migrant farm labor center governed by this chapter may be operated for an extended period prior to or beyond the standard 180-day period, as further provided in paragraph (8) below, after approval by the department, provided that all of the following conditions are satisfied:
(3) In no event shall the rent during the extended occupancy period exceed the average daily operating cost of the center, less any subsidy funds available pursuant to paragraph (1) or (2). With respect to an extended occupancy beyond the standard 180-day period, households representing at least 25 percent of the units in the center shall have indicated their desire and intention to remain in residency by signing a petition to the local entity to keep the center open for an extended period at rents that are the same or higher than rents during the regular period of occupancy. Each household shall receive a clear bilingual notice describing the extended occupancy options attached to the lease.
The Legislature finds and declares that because the number of residents may be substantially reduced during the extended occupancy period, a rent increase may be necessary to cover operating costs. It is the intent of the Legislature that the public sector, private sector, and farmworkers should each play an important role in ensuring the financial viability of this important source of needed housing.
(5) Before approving or denying an early opening or an extension and establishing the rents for the extended occupancy period, both of which shall be within the sole discretion of the department, the department shall take into consideration all of the following factors:
(d) The Legislature finds and declares that variable annual climates and changing agricultural techniques create an inability to accurately predict the end of a harvest season for the purposes of housing migrant farmworkers and their families. Because of these factors, in any part of this state, and in any specific year, one or more migrant farmworker housing centers governed by this chapter need to open early or remain open up to a total of 275 days to allow the residents to provide critical assistance to growers in harvesting crops while also fulfilling work expectations that encouraged them to migrate to the areas of the centers. In addition, if the centers close prematurely or open late, the migrant farmworkers often must remain or reside in the areas to work. During this time they will not be able to obtain decent, safe, and affordable housing and the health and safety of their families and the surrounding community will be threatened.
The Legislature therefore finds and declares that, for the purposes of any public or private right, obligation, or authorization related to the use of property and improvements thereon as a 180-day migrant center, an extended use of any housing center governed by this chapter pursuant to this section is deemed to be the same as the 180-day use generally authorized by this chapter.
