Per your calculation,it shows one-story (R=6.5) building analysis only. Assuming the new interior framing should have its own independent lateral support system, including 2nd floor ceiling. No shear transfer into and supported by the existing building. In fact, plan shows interior floor diaphragm is anchored to the existing exterior walls. Part of the lateral force are supported by the existing building. However, no design and justification. This is conflict with the calculation as well. In addition, the partitions between 2nd level and roof does not have any top support design and details showing this is 1-story addition and not supported by existing roof diaphragm.

Provide drift calculation to justify (ASCE 7-16 12.12.3)Provide a complete and consistent grid system with grid lines for each lateral line of resistance on structural framing plans. Lack of grid lines makes the review process difficult and may delay the plan review and permit process.Provide calculation to check roof diaphragm design at the exterior1-story addition building (e.g. electrical, water room, garage). Using lower R value of the two building system for design force. (ASCE 7 Section 12.2.3.3)In the common wall between the new addition and existing building, justify the existing wall to support newly added lateral force from the tributary area of the new roof addition. Using lower R value of the two building system for design force from the tributary area. (ASCE 7 Section 12.2.3.3)Provide lateral support for the full height partitions on the between 2nd floor and roof. Demonstrate they are not supported by the existing roof. Per your design, new interior addition is design as an independent structure. Revise plans and provide connection details.Diaphragm discontinuities, openings and reentrant corners(ASCE 7 Section 12.10.1): At diaphragm discontinuities, such as openings and reentrant corners, the design should show that the dissipation or transfer of edge (chord) forces combined with other forces in the diaphragm is within shear and tension capacity of the diaphragm. (E.g. hallway openings, 2-story openings by garage, stairway opening…)PC2: The response is not clear.The new parapet shall be 30” minimum high above adjacent roof.
