Understanding HUD Standards for Manufactured Homes in California

If you rent a mobile or manufactured home in California, it's essential to understand how federal HUD standards and state rules protect your safety, housing quality, and tenant rights. Knowing the basics of these requirements can help you address maintenance, repair, or compliance concerns quickly and confidently.

What Are HUD Standards and How Do They Affect Manufactured Housing?

The U.S. Department of Housing and Urban Development (HUD) sets and enforces nationwide health and safety construction standards for manufactured homes (sometimes called mobile homes). In California, these rules ensure that manufactured homes are built and maintained to exacting safety codes. Any manufactured home built after June 15, 1976 must meet the HUD Manufactured Home Construction and Safety Standards.

  • Durability and Weather Protection: Homes must withstand local weather with sturdy roofs, walls, and anchoring.
  • Fire and Electrical Safety: Strict rules for smoke alarms, fire exits, wiring, and utilities apply.
  • Sanitation: Plumbing, bathrooms, and kitchens must be in good working condition.

California’s Department of Housing and Community Development (HCD) enforces these standards, as well as state-specific codes for setup, park maintenance, and occupancy.

California’s Additional Protections for Renters in Mobile Home Parks

Beyond HUD’s requirements, California law provides extra protection for those renting or leasing in mobile home parks under the Mobilehome Residency Law (California Civil Code §§ 798–799.79). This law covers eviction, rent increases, notice of rule changes, and maintenance obligations for landlords and park owners.

  • Landlords must keep shared park areas in safe condition and maintain utilities.
  • Renters must receive at least 90 days' written notice for rent increases.
  • Eviction rules specify reasons and require legal process.

Your Rights to Repairs and Maintenance

If you experience problems with the structure, basic utilities, or safety hazards, both HUD standards and California law require your landlord to fix them in a reasonable time. If they fail to do so, you may have specific rights to request repairs or report violations.

How to Request Repairs

Tip: Keep photos and documentation of the problem and all communications with your landlord or park manager.

Key Forms for Mobile Home Renters

  • Mobilehome Complaint Form (HCD MP 500): For reporting park conditions, code violations, or unresolved safety issues.
    Access the official form here.
    Example: If you report broken water lines and receive no action, use this form to file a formal complaint with HCD.
  • Notice of Rent Increase: Landlords must provide this written notice at least 90 days in advance (no official state form; a clear, dated written letter is required under Civil Code § 798.30).
  • Notice of Termination/Eviction: Must be in writing and cite a reason from the Mobilehome Residency Law. Usually 60 days’ notice applies, but may vary.
    For official guidelines, visit the California Department of Consumer Affairs Mobilehome Residency Law Handbook.

California does not require renters to use a specific state "tenancy application" form. Always request receipts for rent or deposits.

Which Tribunal Handles Mobile Home Disputes?

The main authority for complaints about manufactured housing conditions or park management is the California Department of Housing and Community Development (HCD). For disputes over eviction or rent, cases may go to the civil division of your local California Superior Court. Renters can also seek mediation help from California’s Office of the Attorney General.

For immediate issues about unsafe conditions, use the HCD Mobilehome Complaint Form. For rent disputes or eviction, contact your local court or a legal aid office.
