Important Notes

Arizona spans from hot Sonoran Desert (Phoenix 115°F+) to cold mountain forests (Flagstaff 7,000 ft elevation). This extreme diversity means building requirements vary dramatically by location. Key hazards: WILDFIRE — WUI zones cover much of the state, requiring fire-rated materials. MONSOON — summer storms bring high winds (60+ mph microbursts), dust storms (haboobs), and flash flooding. EXTREME HEAT — cooling load is the primary energy concern in southern AZ. HAIL — periodic hailstorms in monsoon season. Snow loads in northern mountains can reach 100 psf. Seismic risk is moderate (Category B/C). The state has 5 IECC climate zones (2B, 3B, 4B, 5A, 5B) — more diversity than most states.
