The uniform design live load in unoccupied landscaped areas on roofs shall be 20 psf 0 958 kn m2.
The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures.
Where uniform roof live loads are reduced to less than 20 psf 0 96 kn m 2 in accordance with section 1607 12 2 1 and are applied to the design of structural members arranged so as to create continuity the reduced roof live load shall be applied to adjacent spans or to alternate spans whichever produces the most unfavorable load effect.
These loads are not considered to be per manent because of their inherent degree of variability with respect to time see the definition of loads in ibc 202.
An nahb proposal amended the 2015 ibc to restore the traditional 20psf roof live load requirement for porches patios or canopies on one and two family dwellings but the issue remains for multifamily buildings.
