Park Operation

Information Bulletins provide additional helpful information about park operation. Check for new bulletins periodically.

Permit to Operate

A park must secure a permit to operate prior to operating a mobilehome park. The park owner is subject to penalties for failure to submit a permit application, form HCD MP 500 (PDF) more than 60 days after the due date.

Permit to Operate related fees (PTO fees, penalties, change of operator, etc.) can be paid online using HCD’s online fee-payment system. You must have a DTN and a park zip code to make a payment online. This information can be found on your billing summary or by contacting a program representative. Please contact the Permit to Operate desk at or (800) 952-8356 for more details.

Fire Hydrant Certification

Annual submission of the Private Fire Hydrant Test and Certification Report, form HCD MP 532 (PDF) is required to obtain a permit to operate. All parks must submit this form annually, even parks without fire hydrants or water methods. The public may contact the Permit to Operate desk at or (800) 952-8356 to obtain additional information concerning fire hydrant certification.

Emergency Preparedness Plan

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. The booklet, Emergency Plans for Mobilehome Parks (PDF) is a guide for preparation of a plan. The EPP is required in order to receive a permit to operate.
