decks Industry grew out of the Mobile Home

business

Preemptive Code This means that no local or state

government can increase or decrease the code requirements for the construction of a manufactured home.

The preemption applies to the “box” Wisconsin’s one- and two-family building

code applies only to the foundation, additions, steps and deck – not the home itself

Home Inspections

The HUD Code calls for inspections in the plant for the home

If there are unusual aspects of the home that cannot be inspected in the plant, then a field inspection is done for the home.

Wisconsin law requires all manufactured home installations to be inspected

What’s What Mobile Home – built prior to July 1976 Manufactured Home – built to HUD Code

after July 1976 Modular Home – built to state building code

(UDC in Wisconsin) Using the term “modular home” is only

proper if it relates to a home built to the state code. A HUD Code home is never a modular home.
