NOTES
(1) The IRC requires a minimum live load - See R301.6.
(2) This table is informational only in that actual site
elevations may vary. Table is only valid if site elevation
is within 100 feet of the listed elevation.
(13) Section R301.6 is deleted and replaced with the following:
R301.6 Utah Snow Loads. The ground snow load, Pg, to be used in the determination of design snow loads for buildings and other structures shall be determined by using the following formula: Pg = (Po2 + S2(A-Ao)2)0.5 for A greater than Ao, and Pg = Po for A less than or equal to Ao.
WHERE
Pg = Ground snow load at a given elevation (psf)
Po = Base ground snow load (psf) from Table No. R301.2(5a)
S = Change in ground snow load with elevation (psf/100 ft.) From Table No. R301.2(5a)
A = Elevation above sea level at the site (ft./1000)
Ao = Base ground snow elevation from Table R301.2(5a) (ft./1000)
The building official may round the roof snow load to the nearest 5 psf. The ground snow load, Pg, may be adjusted by the building official when a licensed engineer or architect submits data substantiating the adjustments. A record of such action together with the substantiating data shall be provided to the division for a permanent record.
The building official may also directly adopt roof snow loads in accordance with Table R301.2(5b), provided the site is no more than 100 ft. higher than the listed elevation.
Where the minimum roof live load in accordance with Table R301.6 is greater than the design roof snow load, such roof live load shall be used for design, however, it shall not be reduced to a load lower than the design roof snow load. Drifting need not be considered for roof snow loads less than 20 psf.

Winder treads shall have a minimum tread depth of 10 inches (254 mm) measured as above at a point 12 inches (305 mm) from the side where the treads are narrower. Winder treads shall have a minimum tread depth of 6 inches (152 mm) at any point. Within any flight of stairs, the greatest winder tread depth at the 12 inch (305 mm) walk line shall not exceed the smallest by more than 3/8 inch (9.5 mm).
R311.5.3.3 Profile. The radius of curvature at the leading edge of the tread shall be no greater than 9/16 inch (14.3 mm). A nosing not less than 3/4 inch (19 mm) but not more than 1 1/4 inches (32 mm) shall be provided on stairways with solid risers.
