(n) This section shall not apply to a local agency until July 1, 2026, unless the local agency adopts an ordinance or local transit-oriented development alternative plan deemed compliant by the department before July 1, 2026. It shall not apply within an unincorporated area of a county until the 7th regional housing needs allocation cycle.
This act is an urgency statute necessary for the immediate preservation of the public peace, health, or safety within the meaning of Article IV of the California Constitution and shall go into immediate effect. The facts constituting the necessity are:
(a) Mobilehome and recreational vehicle parks are widely considered to be naturally occurring affordable housing, and are home to 1.6 million Californians who are often older and lower-income individuals.
(b) To maintain California’s progress on slowing down the increase in homelessness, we must keep people housed and preserve all varieties of affordable housing.
(c) There are 5,230 active mobilehome and recreational vehicle parks in the State of California with a total of 453,755 lots and spaces.
(d) The average park size is 86 lots or spaces, however the ten largest parks in the state each have over 500 spaces and the largest mobilehome park in California has 923 spaces.
(e) Half of the ten largest mobilehome parks in California are within Senate District 10; three of those are in Sunnyvale and are impacted by Senate Bill 79 (Chapter 512 of the Statutes of 2025). As public transit expands and bus rapid transit systems become more popular, the impacts of Senate Bill 79 on mobilehome and recreational vehicle parks will become more widespread.
(f) For the immediate preservation of the public peace, health, and safety, the Legislature must protect mobilehome, recreational vehicle, and special occupancy parks just as deed-restricted and subsidized affordable housing is protected.
