Framing

TOP PLATES
A double top plate is required, for exceptions see International Residential Code, Chapter R602.3.2.

ROOF AND CEILING FRAMING
Rafter ceiling joist sizes are determined by a 30 psf live load and a 10 psf dead load in combination with span lengths and spacing. Because there are many combinations of span and floor area, this pamphlet will not attempt to address all of these. The reader is referred to the International Residential Code. The minimum sizes will be verified by the Building Inspection office upon review of your project. Engineered trusses may also be used. Truss engineering drawings must be submitted for review and approval at time of framing inspection.

UTILITIES
Electric meter height must remain at 5'6" above grade including finished floor of deck. Proper height of overhead service drop must be maintained at a minimum of 10' above grade and above roofs dependent upon the roof slope and amount of overhang. The meter may need to be moved in some instances, such as if the accessory building is built under an overhead electrical service drop. The meter may not be located in an enclosed room.
