b. ‘Attics without storage’ are those where
any one of the following conditions apply:
(i) the maximum clear height between joist and rafter is
less than 42 inches, or where there are not two or more adjacent trusses with

(ii) there is no attic access greater than the minimum
access opening required by Section R807; or,
(iii) the ceiling joist or truss bottom chord pitch is

For ‘attics without storage,’ this live load
need not be assumed to act concurrently with any other live load requirements.
g. For ‘attics with limited storage’ and
