I've reviewed it, and it appears to be correct. Although you don't need the frontage increase for Part-3, why did you consider that there is no frontage? The ends on Devonshire and Evandale are obviously open. What is the fire separation distance from the building to the property line to the north (at least I assume that is north)?
You say the building is sprinklered, you should indicate that the sprinkler is in accordance with Section 903.3.1.1 (NFPA 13). R occupancies are required to be sprinklered by any of the systems in Section 903.3, but only the NFPA 13 can be used for the sprinkler increase.
Also, you don't state that the S-2 is a parking garage. Only an S-2 parking garage can be used used according to 509.2.
Hopefully somewhere else on the sheet you indicate occupancies and construction type.
Finally, I'm looking at some alternatives to avoid fire walls; Can the buildings A, B/C, and D be treated as separate buildings? Do they have adequate fire separation distance? What are the opening areas per floor at these ends, or do they even have openings?
