Unreported / Non-Citable
Background
The Ninth Circuit upheld Santa Barbara’s mobilehome vacancy-control ordinance against a constitutional takings challenge, allowing the city’s 10% cap on rent increases when a mobilehome changes owners to remain in force. The ruling is unpublished and therefore generally nonprecedential, but it applies established takings principles to a recurring California housing issue.
1210 Cacique Street, LLC owns the Flamingo Mobilehome Park, where residents own their homes but lease the underlying spaces. The company alleged that Santa Barbara’s reenacted vacancy-control rule reduced the park’s value by 92.5%. A federal district court dismissed the claim with prejudice, meaning the owner could not amend it, and the owner appealed.
The claim arose under the Penn Central framework for regulatory takings—government restrictions that do not physically seize property but may be so burdensome that the Constitution requires compensation. That framework weighs economic impact, interference with reasonable investment-backed expectations, and the character of the government action.
The Court’s Holding
The panel affirmed dismissal even while assuming, without deciding, that the alleged 92.5% loss in value was plausible and could favor the owner. Economic loss alone was not enough. The other two factors weighed decisively for the city.
On investment-backed expectations, the court reasoned that mobilehome parks have long operated in a heavily regulated environment. Santa Barbara had maintained rent stabilization for decades, had previously used an identical vacancy-control provision, and had repealed it only because intervening law required that result. When Cacique bought the park, federal decisions had repeatedly rejected similar challenges. The owner therefore could not reasonably expect the regulatory scheme to remain permanently unchanged.
The court also characterized vacancy control as an economic regulation that adjusts the benefits and burdens of housing policy, not as the functional equivalent of a physical occupation. Alleged market distortions—such as higher mobilehome sale prices—did not change that character. Judge Miller dissented, concluding that the detailed allegation of a 92.5% loss and the asserted difference between ordinary rent control and vacancy control deserved factual development rather than dismissal at the pleading stage.
Key Takeaways
- A large alleged decline in property value does not, standing alone, establish a regulatory taking under the Penn Central test.
- Purchasers of property in a long-regulated market face difficulty claiming a reasonable expectation that existing controls will never be strengthened or reenacted.
- A city’s earlier use of the same restriction can make later reenactment foreseeable, even after a long period without that restriction.
- California mobilehome rent controls are generally treated as broad economic regulation rather than a physical appropriation of property.
- The dissent highlights a continuing pleading-stage dispute: when an owner alleges an extreme value loss, some judges may favor allowing discovery before deciding the full takings balance.
Why It Matters
For California mobilehome park owners and local governments, the decision shows how difficult an as-applied takings claim can be when the property was acquired against a longstanding regulatory backdrop. Owners evaluating acquisitions should document not only current restrictions, but also a jurisdiction’s regulatory history and stated housing-policy goals; those facts may shape whether future regulatory changes were reasonably foreseeable.
For cities, the ruling supports carefully framed vacancy controls that operate as part of an established rent-stabilization program. Because this is an unpublished memorandum and includes a dissent, practitioners should treat it as a useful application of existing law rather than a new binding rule.
