You need a building permit to install a manufactured home

To install a manufactured home or mobile home, a building permit is required.

There are three different permit types for manufactured dwellings:

  1. Manufactured Dwellings on an Individual Lot (MI)
  2. Manufactured Dwellings in Parks (MP)
  3. Residential (RS) for accessory structures (these structures must be constructed per the International One and Two Family Dwelling Code)

Manufactured homes include modular homes, factory-built homes, and permanent mobile homes (mobile homes without wheels, on a foundation).

Depending on the scope of work, your project may also need electrical, plumbing, or mechanical permits ↗.

Who can do the work?

Contractors must have a license to work in Oregon. The Oregon Construction Contractors Board (CCB) ↗ issues licenses to contractors. The permit application and the company materials must list the license number. Need help finding a contractor? The CCB website has good tips on how to search for one. Plumbing and Electrical contractors have additional license requirements.  

If you are a homeowner doing the work yourself, then you can sign the trade permit applications ↗. You cannot do the electrical work yourself. You must hire a licensed electrical contractor to do the electrical work. The State of Oregon has some helpful information for homeowners:
