Introduction to Manufactured Housing
1
The Home, the Site and You
To be a professional manufactured
home installer you need to
understand HUD Code homes, how to
deal with site conditions and what
you need to do to maintain your
license.
2
So Just What is a Manufactured
Home?
 Built to a federal building code
 A nationally preemptive code
 Code is based on performance
 3rd party inspection system
 Built in sections
 Delivered to the site
 Some site constructed elements such as
decks
 Industry grew out of the Mobile Home
business
3
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
4
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
5
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.
6
 Today’s manufactured housing
delivers outstanding quality and
performance due to the systems
approach to its construction
 Manufactured homes benefit from
economies of scale
 A wide range of styles and exterior
finishes are available
7
 Flexibility in the production process still
permits customization to meet your
lifestyle and needs
 Smart buyers are also looking for the
Energy Star label

 Multi-section homes create special
issues for installers. Be alert to:
 Marriage line pier locations
 Electrical, HVAC and Plumbing crossovers
 Proper connection of the halves

Home Placement
 On land owned by homeowner
 Located in MH Community

 Placements in MH communities result in
special considerations. Be alert to:
 Permission to work on land not owned by the
homeowner
 Buried electrical wires and plumbing that may
not be located on site drawings

What does a Manufactured
Home look like?
Could be a single
section home
with vinyl skirting.
Proper foundations
to avoid
buckling of
skirting is
important for
these homes

HUD Code in the Plant
 Home is designed and then approved by a
3rd party Design Approval Primary
Inspection Agency (DAPIA)
 Home is constructed and then inspected
by 3rd party In-plant Approval Primary
Inspection Agency (IAPIA)
 Home must be habitable when leaving the
plant – all systems must be in working
order when the home leaves the plant.
(electrical, HVAC, plumbing)

Characteristics of the HUD Code
Home
 Permanent chassis which cannot be
removed
 Red seal on each section
 Dataplate details all of the system

Data Plate
 Inside the home located near
the electrical service is the
Data Plate
 The 8.5 by 11 inch document

wind zone, thermal zone and
mechanical system details.
24
Data Plate also includes
 Manufacturer’s Name
