Analysis by the Legislative Reference Bureau
This bill makes numerous changes to laws governing mobile homes,
manufactured homes, and the mobile and manufactured housing industry. The
changes primarily include the following:
Definitions of "mobile home" and "manufactured home"
Under current law, there are several different definitions of the term "mobile
home" and of the term "manufactured home." Also, under current law, "mobile home"
is often used as a general term that includes "manufactured home." Because of
changes in the mid-1970s in federal laws that define and regulate mobile and
manufactured homes, only manufactured homes as defined under current federal
law are being constructed today. This bill creates a single definition for "mobile
home" and a single definition for "manufactured home" that apply more generally
throughout the statutes by doing the following:
1. The bill establishes the definition of "mobile home" that is used in the
subchapter of the statutes regulating the mobile and manufactured housing
industry as the general definition of "mobile home" in the statutes. Thus, under the
bill, a mobile home generally means a vehicle manufactured or assembled before
June 15, 1976, that has an overall length of more than 45 feet, that is designed to be
towed as a single unit or in sections on a highway by a motor vehicle, that has walls
of rigid noncollapsible construction, and that is equipped and used, or intended to be
used, primarily for human habitation. Under the bill, "mobile home" includes the
mobile home structure, its plumbing, heating, air conditioning, and electrical
systems, and all appliances and all other equipment carrying a manufacturer's
warranty.
2. The bill establishes the definition of "manufactured home" that is used in the
subchapter of the statutes regulating the mobile and manufactured housing
industry as the general definition of "manufactured home" in the statutes. Thus,
under the bill, a manufactured home generally means either a mobile home or a
structure designed to be used as a dwelling, either with or without a permanent
foundation, that complies with the federal standards established for manufactured
homes.
In addition, the bill makes the use of these terms more consistent with their
definitions by doing the following:
1. The bill inserts references to "manufactured home" in certain places in
current law that refer only to "mobile home" if the use of mobile home under current
law is general and meant to include manufactured homes. The bill also inserts
references to "manufactured home" in the statutes governing the treatment, for
property and other tax purposes, of mobile and manufactured homes as either
improvements to real property or as personal property.

2. The bill changes references to "mobile home" to be references to
"manufactured home" in certain statutes that pertain only to structures that are
newly constructed, since under federal law only manufactured homes are now being
constructed.
3. The bill changes references to "manufactured buildings" to be references to
"modular homes." Under current law, such buildings are those that are intended for
use as a dwelling, are of closed construction, and are fabricated or assembled in
manufacturing facilities for installation at the building site or they are of open
construction and are made or assembled in manufacturing facilities away from the
building site for installation on the building site for which certification is sought by
the manufacturer.
Monthly fees
Current law requires each city, town, or village (municipality) in which a mobile
home park is located to collect from each mobile home occupying space in the park
a monthly parking permit fee. The fee is calculated based on the value of the home
multiplied by the general property gross tax rate, less certain credits. The total is
divided by 12 to represent the monthly mobile home parking permit fee. Current law
provides that the municipality may require the mobile home park operator to collect
the fee from the mobile home owner.
The bill also replaces the term "parking" wherever it appears in the phrase
"monthly parking permit fee" in the statutes with the term "municipal," so that the
fee is called a "monthly municipal permit fee."
Regulation of recreational vehicles
The bill makes minor modifications to the definition of "recreational vehicle,"
and generally clarifies the applicability of certain vehicle regulations to recreational
vehicles. The bill also uses the term "recreational vehicle" in place of "mobile home"
where "mobile home" is used to refer to temporary living quarters.
Regulation of manufactured home communities
Under current law manufactured home communities and mobile home parks
are regulated by the Department of Commerce (commerce) and by the municipality
in which the community or park is located. Generally, under current law, the terms
"manufactured home community" and "mobile home park" are used in the statutes
to describe similar places.
For purposes of regulation by Commerce, current law provides that a
manufactured home community is any plot of ground upon which three or more
manufactured homes that are occupied for dwelling or sleeping purposes are located.
For purposes of regulation by the local municipality, current law provides that a
mobile home park means any plot of ground upon which two or more units, occupied
for dwelling or sleeping purposes are located. Consistent with regulation by
Commerce, this bill increases from two to three the number of mobile or
manufactured homes that must be located on a plot of ground before the ground is
subject to regulation by the municipality in which the ground is located.
This bill also replaces the term "park" with "community" throughout the
statutes where the term is used in reference to mobile home or manufactured home
parks.

Sewer and water service to manufactured housing communities
This bill prohibits any public utility that provides metered water service to a
manufactured home community as a whole via a single master meter from charging
a fee for water lost in distribution between the master meter and the unit meters,
except to the extent that the loss exceeds the public utility's system-wide rate of loss.
