Park management must develop an Emergency Preparedness Plan (EPP) to inform residents about what to do in preparation for and in the event of an emergency.

Park owners / operators that have experienced financial hardship as a result of the 2022/2023 winter storms, or other declared state of emergency may be eligible for a permit to operate (PTO) penalty fee waiver. Only PTO penalty fees are eligible, not annual permit to operate fees.

How to Apply

Mobilehome and special occupancy park owners and operators can apply for a PTO penalty fee waiver by submitting a letter or application to the enforcement agency with documentation supporting their inability to pay PTO penalty fees due to an economic hardship caused by the qualifying state or federal emergency.

Visit the Office of the Governor’s Newsroom to determine if there is a qualifying state emergency in your area.

Visit Federal Emergency Management Agency (FEMA) Current Disasters to determine if there is a qualifying federal emergency in your area.

Supporting documentation and letter or application must be submitted within one year of the qualifying state or federal emergency and include:

• Applicant’s name, address, phone number, and email (if applicable).
• A statement explaining how the qualifying state or federal emergency has caused an economic hardship that prevents the applicant from paying the annual PTO fees on time.
• Documentation supporting and confirming the applicant’s statement of economic hardship.
• Supporting documentation may include, but is not limited to:
  • Tenant rent logs
  • Accounting records of rent not collected during the State of Emergency
