1. Page 1.1., Simplified wind load method can't be used because of the
irregularity shape of this building plan per IBC section 1609.6.1.1. #5.
2. Page 4.2, Please recheck the shear wall aspect ratio for the shear wall line
1 that is only 1.75 ft long (from calculation page 4.2), and reduce the
shear wall capacity accordingly per IBC table 2503.3.3.
3. The plan is with re-entrant corner irregularity (L shape) per IBC table
1616.5.1.1. Please provide diaphragm design to make sure the
maximum diaphragm dimension ratio is within code limit per IBC table
2305.2.3. Provide design, detail and calculation for each diaphragm
chord, collector, blocking, strap, please indicates the assumed
diaphragms in plans. An increase of 25% is required in the calculated
design forces for connections of diaphragms to collectors and vertical

6. Sheet # 6, HDR -9 Garage header 5 118 X 16'/ and FB -4 are supporting
discontinuous shear wall from above. In the event of an earthquake,

the shear walls. Please recheck the adequacy of these beams with
combined seismic and gravity load per IBC 1620.2.9.
7. Sheet # 9, Section shows bottom of footing below the undisturbed ground
surface is less than 12 °, which is in conflict with IBC section 1805.2.
