Modular Vs Manufactured
You May have heard of each, But do you know the difference between HUD code and Modular or UBC, IBC, IRC code homes. Let us give you a brief explanation. HUD Code -- (Manufactured Homes) A national “performance” code preempts all local, county and state codes. After initial and final inspections at the factory, no additional inspections need to be made to the home itself, only the foundation and construction need final inspection for occupancy. IRC. Code – (Modular Homes) designed to meet the exact building codes as site built homes for the specific state and local jurisdiction in which the home will be placed. We refer to these homes as I-Code and defines them as the following: -2003 International Residential Building Code [IRC] -2003 International Building Code [IBC] -1997 Uniform Building Code [UBC] Modular. The codes that govern the construction of modular homes are the exact same codes that govern the construction of any site constructed home. In the United States, all modular homes are constructed according the International Residential Code (IRC), UBC, IBC, BOCA or the code that has been adopted by the local jurisdiction. The materials are the same as site constructed homes. Wood frame floors, walls and roof is the most typical. Some modular even include brick or stone exteriors, granite counters and steeply pitched roofs. All modular homes are designed to sit on a perimeter foundation or basement. Most companies have standard plans. However, all modular buildings can be custom built to a clients specifications. Today's designs include multi-story units, multi-family units and entire apartment complexes. Because the public is not as familiar with the terminology of a modular home and often associate them with "mobile" or "manufactured" homes which are governed under completely different constructions guidelines that are not the same as site built homes many companies are now referring to the development of a modular home as Off-Site Construction. Modular home designs can be customized for local zoning codes. For example, homes built for final assembly in a hurricane prone area can have additional bracing built-in to meet local building codes. Many home buyers are having their modular homes built with earthquake bracing in consideration of earthquake protection. Modular homes are generally assembled with a permanent foundation. Additionally, in the US, the Uniform Standards of Professional Appraisal Practice allow site-built homes to be used as comparators to modular homes in real estate appraisal. Building strength Modular homes are generally designed to be initially stronger than traditional homes by, for example, replacing nails with screws and adding glue to joints. This is supposed to help the modules maintain their structural integrity as they are transported on trucks to the construction site. When FEMA studied the destruction wrought by Hurricane Andrew in Dade County Florida, they concluded that modular and masonry homes fared best compared to other construction. Typically, a modular home contains about 10% to 20% more lumber compared to traditional stick-built homes.The height that a modular structure can be built to depends on jurisdiction. Exterior wall surfaces can be finalized in the plant production process or in the case of brick/stone veneers field applications may be the builders choice. Manufactured Homes: Modular and manufactured homes are similar in the fact that both are built "off-site" and then transported to their permanent site. The biggest differences come in the governing standards, foundational options and how they are transported. In the United States, the term manufactured housing specifically refers to a house built entirely in a protected environment under a federal code set by the US Department of Housing and Urban Development (HUD). The term mobile home describes factory-built homes produced prior to the 1976 HUD Code enactment. Both types of homes - manufactured and modular - are commonly referred to as factory built housing, but they are not identical. Modular homes are transported on chassis. The house is usually in two pieces and is hauled by two separate trucks. Each frame has five or more axles, depending on the size of the house. Once the house has reached its location, the axles and the tongue of the frame are then removed, and the house is set on a concrete foundation. Most modern modular homes, once fully assembled, are indistinguishable from site-built homes.
