What is Your Manufactured Housing IQ?
Take this short test to see where you stand!
Pick the answer that BEST completes the question.
1) According to the code requirements for new Manufactured Homes, which statement below is true?
Wood burning fireplaces are prohibited in bedrooms.
The heat tape receptacle is GFCI protected.
Tamper proof receptacles are not required.
Carbon monoxide alarms could be required by local code.
2) What is a difference between a Manufactured and a Modular Home?
There is little difference, the terms are very interchangeable.
Modular homes are built to a state building code, manufactured homes are built to a federal building code.
Only modular homes may be placed on a permanent foundation.
Only manufactured homes have a permanent chassis.
4) A Manufactured Home is designed to remain transportable for how long?
Until a secondary sale or it is relocated.
5) A Manufactured Home, intended to be installed in Ithaca NY, approximately 75 miles south of the New York State Thruway, would need to be designed for which roof snow load?
8) What is the typical load on a frame support pier, if the piers are spaced 8’ apart under a 14’ wide home in the south roof load zone?
Required only on single section homes less than 56’ long.
Required in certain circumstances, by some manufacturers, but not all manufacturers.
Not required on any homes.
Report the information to the manufacturer.
Nothing, for home is older than 5 years.
Provide the manufacturer’s service department contact information.
Wood burning fireplaces are prohibited in bedrooms at §3280.709(g)(iv) of the Manufactured Home Construction and Safety Standards (HUD Code). The exclusion for GFCI protection at the heat tape receptacle was removed with a code change on December 2013, see §3280.806(b). The HUD Code adopts the 2005 National Electric Code (NEC) by reference. Tamper proof receptacles were not required until the 2014 NEC, so they are not required. §3280.801. Since the HUD Code is silent regarding carbon monoxide alarms, they could be required by local code.
The correct answer is 5–All of the above are true.
The first difference between a Manufactured and a Modular Home (in some states called an Industrialized Home) is really the governing body that establishes the building code. Modular Homes are designed and constructed to the state or local building code, while Manufactured Homes are designed and constructed to meet the federal code as established by US Dept. of Housing & Urban Development (HUD). While it is true that there are other differences of both construction code and program requirements, it all starts with the body that oversees the program.
Multiple floor joists under certain end walls or partition walls in a Manufactured Home is one indicator that the wall is a shear wall and it transfers horizontal (wind) loads through the floor, to the chassis and down to the anchoring system. The side walls and marriage walls transfer all vertical (snow loads).
A Manufactured Home is designed to remain transportable for its intended life. See §3280.903 of the HUD Code.
The correct answer is 3. For its intended life.
The majority of the country is in the South Roof Snow Load Zone (20 PSF of snow). In the northeast, the Middle Roof Snow Load Zone starts approximately at the New York State Throughway. See the map below which is also found at §3280.305(c)(3) of the HUD Code. Ithaca NY is south of the Middle Roof Load Zone. FYI….there is no Mid-Atlantic Roof Load Zone ( I made it up).
The minimum requirement for a state to “partner” with HUD as a State Administrative Agency (SAA) is that they must “Handle Consumer Complaints” (a little more complicated than that, but you get the idea). See 3282.302(b) of the Manufactured Home Procedural and Enforcement Regulations. While many states have elected to take on additional responsibilities such as overseeing installation, etc…they are not required. I know that a lot of state budgets are being pinched and as a result many of these partnerships are in jeopardy. Don’t be surprised to see less state involvement and more HUD take over unless the current situation changes.
The correct answer is 2. Handle consumer complaints.
In general, a single concrete block pier (8” x 16”) up to 36” high has an 8,000 lbs. capacity! A few manufactures (Clayton for one) might be slightly more conservative, but in general, 8,000 is acceptable.
The correct answer is 3. 8,000 lbs.
The average pier load in the south roof load zone, with an 8’ spacing, average 14’ wide home is between 5,000 lbs. and 5,600 lbs. (Chart below is 5,130 lbs.). But keep in mind, some manufacturers may be different (Ritz Craft for example). Double check the instructions for every home.
The correct answer is 1. 5,000 lbs.
In Wind Zone 1, end wall frame anchoring is a real mixed bag. Certain manufacturers require them in all cases. Most require them only for very short homes (under 56’ in length). A few (three that I know of) don’t require them at all in Wind Zone 1. (Generally, the “strong arm” anchoring systems are adaptable for end wall anchoring, you should check them out).
The correct answer is 3. Required in certain circumstances, by some manufacturers, but not all manufacturers.
If a consumer reports a problem to the dealer who sold the home after 6 years of occupancy, the dealer is obligated to report the information to the manufacturer. Don’t over think it, there is no warranty or time limits on this requirement. All information that may indicate problem is to be forwarded to the manufacturer. Just pass it along! See §3282.256(b) of the Manufactured Home Procedural and Enforcement Regulations for more on this issue.
The correct answer is 1. Report the information to the manufacturer.
Installers are required to keep records of Manufactured Homes that they install for a minimum of three years! See § 3286.413(b) of the Manufactured Home Installation Program. I believe that most installers are not in this habit and equally important, don’t know which records to keep! I will have to write on this topic in the very near future. Remember, records are your best defense in any dispute!
The correct answer is C. Three years!
0-2 wrong? You are a manufactured housing master!
3-4 wrong? You are a manufactured home rookie!
5 or more wrong? You need to attend my next training class!!!
