- Classifies large assembly buildings (2,500+ occupants) as Risk Category III
- Aligns snow load maps and rain load rules with ASCE 7-16
- Requires special inspection of mass timber anchorage and connections
- Adds inspection requirements for fire-resistant systems in large Group R areas
- Introduces frost protection for egress doors at foundation level
- References ACI 117 and ITG 7 for concrete construction tolerances
