Building Code (IBC Ch. 5)

Construction Type: Type IV-C; mass timber · ~$138/sf base
Stories to Realize FAR: ~7; No height cap — FAR ÷ coverage
Net Realizable Units: 59; 80% net-to-gross vs. 59 gross

Realizing this zoning envelope needs about 7 stories — above the 4-story wood-frame limit — so it requires Type IV-C (noncombustible or mass timber). Zoning permits the density; the building code raises the hard cost to reach it.

Model a specific massing to see the construction type it requires (zoning capacity above is unchanged):
