Petaluma Park Drama: Rent Rules, Lawsuits and the Future of Mobile Homes

Petaluma’s Little Woods mobile‑home park sits at the heart of a legal battle that may set precedent for towns across California. The owners, led by Nick Ubaldi, plan to shut down the 78‑unit park on Lakeville Highway—an action that would force almost 100 residents to relocate.

The Conflict

• Owner’s Objective: Close the park, citing rent‑control rules and relocation costs as burdens.
• Residents’ Position: Protect their homes, which are low‑income tenants of the land beneath their mobile homes.
• Legal Context: California tightened laws in 2021, requiring a costly relocation study and city‑council vote before a park can close.

Key Developments

• June 2024: Owners announce intent to shut down the park.
• May 2025: Owners pay ~$200,000 for a relocation assessment; they later sue the city over the cost.
• City’s Response: Assistant attorney states the report is nearly finished; city aims to prevent “unwarranted displacement.”
• National Involvement: A Windsor resident is fighting an emergency ban on closing his family’s park, with a national legal group backing him.

Stakeholders

• Nick Ubaldi: Owner of Little Woods and at least six other parks in Sonoma and Napa counties; also works for Harmony Communities, a major park operator.
• Harmony Communities: Manages ~80 parks (as of 2025); residents report harsh enforcement, eviction threats, and cost pass‑throughs.
• Representative Mike Thompson: Calls for investigations into unfair practices by large park investors and anti‑competitive behavior.
• Christopher Brown: Long‑time resident, fears losing his home; cites high stress levels and a proposed rent increase to $660/month.

The Stakes

• For Residents: Potential loss of home, high relocation costs, and a struggle against owners with deep pockets.
• For Owners: Claims that rent limits “strangle” their business; argues the park’s value is declining with inflation.
• For California: The outcome could shape how mobile‑home park closures and rent regulations are handled statewide.

What’s at Play

• Legal Process: Relocation study, city council vote, and compliance with 2021 state law.
• Economic Factors: Rent increases tied to inflation, owners’ investment returns, and residents’ affordability.
• Social Impact: Stability of low‑income communities tied to mobile‑home parks.

The case remains unresolved, with the city balancing owner rights against protecting vulnerable residents. Its outcome may set a benchmark for similar disputes across California.
