3.1 Helena. The City of Helena is in the process of revising their zoning regulations. Current zoning regulations do not define manufactured homes separately from mobile homes. As such, manufactured are restricted in R-1 and R-2 districts without a conditional use permit. The Helena ordinance does not conform to the language in the current state codes.

3.2 Billings. The Billings ordinance defines three classes of manufactured homes. All must meet the HUD standards, be composed of one or more components, each of which was substantially assembled in a manufacturing plant and designed to be transported to the home site on its own chassis, and exceeds 40 feet in length and 8 feet in width. 

Manufactured home, Class A. A manufactured home constructed after July 1, 1976, that meets or exceeds the construction standards promulgated by the U.S. Department of Housing and Urban Development that were in effect at the time of construction and that satisfies each of the following additional criteria:

a. The home has a length not exceeding four (4) times its width;

b. The pitch of the home‚s roof has a minimum vertical rise of three (3) inches for each twelve (12) inches of horizontal run (3:12), and the roof is finished with a type of shingle that is commonly used in standard residential construction;

c. The exterior siding consists of wood, hardboard, aluminum or vinyl siding comparable in composition, appearance, and durability to the exterior siding commonly used in standard residential construction;

d. A continuous, permanent perimeter foundation, which complies with the Uniform Building Code, is installed under the home; and

e. The tongue, axles, transporting lights, and removable towing apparatus are removed after placement on the lot and before occupancy.

Manufactured home, Class B: A manufactured home constructed after July 1, 1976. That meets or exceeds the construction standards promulgated by the U. S. Department of Housing and Urban Development that were in effect at the time of construction but that does not satisfy the criteria necessary to qualify the house as a Class A Manufactured Home.

Manufactured home, Class C: A manufactured home that does not meet the definitional criteria of a Class A or Class B manufactured home.

The Billings ordinance also provides a definition for a modular home:

Modular home: a dwelling unit constructed in accordance with the standards set forth in the Uniform Building Code and bearing the insignia of the State of Montana, applicable to site-built homes, and composed of components substantially assembled in a manufacturing plant and transported to the building site for final assembly on a permanent foundation. Among other possibilities, a modular home may consist of two sections transported to the site in a manner similar to a manufactured home (except that the modular home meets the Uniform Building Code Standards applicable to site-built homes), or a series of panels or room sections transported on a truck and erected or joined together on the site.

     The Billings codes limit placement of manufactured homes to a Residential Manufactured Home District within the city and to county districts.

3.3 Great Falls. The Great Falls ordinance permits manufactured houses in Suburban, B residential, Residential and O/R transition districts. Manufactured housing is defined as:
