What is the allowable load in psf (pounds per square foot) for mounting solar panels or other equipment on the roof of a mobile/manufactured home?
Friday, August 31, 2018
The live load in psf is noted on the HUD data plate of each mobile home manufactured since 1976. There are three zones: North, Middle, and South. All of Florida is in the South zone, as shown in the roof load map of a Florida mobile home data plate from 2002.
The "Structural Design Requirements” section of the HUD code, Section 24 CFR 3280.305 (b)(2), states the following:
The 20 psf of the South Zone roof load rating is for the temporary weight of someone walking on the roof, and the higher ratings for the Middle and North zones are specifically a snow load allowance. HUD standards do not appear to allow any additional loads for mounting of equipment on a roof, although the local AHJ (Authority Having Jurisdiction) may have a different interpretation of these live load ratings.
