glossary of industry terms
home built in a controlled, factory environment on a permanent chassis that is
designed to be used with or without a permanent foundation when connected to the
required utilities. manufactured homes are built to the federal manufactured
home construction safety standards enforced by the department of housing and
urban development (hud) in washington, d.c. manufactured homes are single story
and are delivered to the home site in one, two, or occasionally, three sections;
they may be placed on private property or in a manufactured home community.
the department of housing and urban development's
code that regulates the home's design and construction, strength and durability,
transportability, fire resistance, energy efficiency and quality control. it
also sets stringent performance standards for the heating, plumbing,
air-conditioning, thermal and electrical systems. the hud code specifically
pre-empts local building codes as they relate to construction codes for
manufactured homes. these homes usually have a steel frame that supports the
weight of the floor system and walls. the steel frame acts as the chassis to
which axles, wheels and brakes are attached for transit to its final resting
site. it should be noted for most of the 1990's, the energy efficiency of
hud-code homes exceeded the efficiency standards of state of michigan
pre-manufactured (or so-called state coded modular homes) and conventional
site-built homes. today, the state has upgraded its efficiency standards to meet
or exceed hud, but that will change once the manufactured housing improvement
act of 2002 is implemented in 2005.
state pre-manufactured or
factory-built homes that begin as components and are
designed, engineered and assembled in a controlled factory environment. these
homes are built to the state of michigan residential building code. this is the
same code that is used to construct any conventional site-built home. components
come together at the building site and the home is completed by a licensed
builder under standards enforced by state and local agencies. modular homes may
be one- or two-story dwellings and are placed primarily on private property;
some may be placed in land-leased communities.
or "frame on modular"
a home built to the state of michigan residential
building code that incorporates a steel i-beam frame. these were built in the
late 1970's and 1980's and are seeing resurgence in popularity. the advantages
are that the steel frame gives more structural integrity to the floor system and
does not warp. a familiar inspector or appraiser will often confuse these homes,
"state pre-manufactured," with a hud-code "manufactured" home. the difference
between these homes is the code under which they are constructed. a steel frame
has nothing to do with the code or tags that are on the home.
in michigan, state pre-manufactured (modular) homes are designed,
built and regulated to adhere to the state of michigan residential building
code. state pre-manufactured homes are often referred to as boca code homes, but
this is an outdated term. since july 2001, michigan has mandated one state-wide
building code that is, for the major part, the same as the international code,
and properly called the state of michigan residential building code. building
officials and code administrators international, inc. is the oldest of three
"model" codes used in the united states. site-built and modular homes previously
fell under this code, which is still used by states in the midwestern and
eastern parts of the country. modular homes may be one- or two-story dwellings
and are placed only on private property.
private land developed as home sites for manufactured homes.
in michigan, most sites are leased to the homeowner for a monthly fee. sometimes
referred to as a land-lease community.
manufactured home delivered to the home site in one, intact section; the average
square footage is 1,120 square feet.
manufactured home delivered to the home site in two or three sections. the
average square footage is 1,715 square feet, but may be as large as 2,400. may
have a (site-built) garage attached after the home is installed.
licensed, professional seller of manufactured homes.
assists in arrangement for financing, and has home installed on home site and
prepared for move-in.
at the home site, exposed to the elements, but may consist of modules of
pre-assembled parts like trusses, doors, windows and pre-cast basement wall
