There are multiple steps involved when constructing a new or altering an existing mobilehome or special occupancy park. There are both state and local government requirements to meet and approvals to obtain. Alterations to an existing utility system, facility, or permanent building within a park require a Permit to Construct from the enforcement agency.
Below you will find information needed to help you navigate the park construction and alteration processes.
