Wildfires and smoke

Risk profile

Arizona wildfire risk comes from desert grass, ponderosa pine, dry lightning, monsoon outflows, and homes built where canyons or washes meet subdivisions.

Home prep before the event

Before red-flag weather, clear the 0-to-5-foot zone next to the house, clean gutters, screen vents, move firewood and patio cushions away, label the gas shutoff, and keep defensible access for engines. Schedule roof, deck, siding, and ember-vent repairs before smoke season.

During-event safety

During evacuation alerts, leave early if instructed, close windows, move combustible items from decks, and do not block roads for fire crews. If smoke is heavy, run filtered air indoors and avoid outdoor cleanup until air quality improves.

Post-event recovery

After a wildfire, wait for official reentry, document structures and contents before ash cleanup, wear respiratory protection, and follow local hazardous-debris instructions. Ask the insurer about smoke, additional living expense, and code-upgrade coverage before signing rebuild contracts. Use FEMA's AZ page at https://www.fema.gov/locations/arizona if a federal disaster is declared, and monitor Arizona Department of Emergency and Military Affairs at https://dema.az.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.

Code references

Code reference: wildfire construction rules are usually local or state WUI adoptions, fire-code amendments, defensible-space ordinances, and ignition-resistant material requirements. Ask the building department and fire district before changing vents, decks, siding, glazing, or access roads.

Flooding

Risk profile

Arizona flood risk is usually fast: monsoon downpours, dry washes, burn scars, and undersized neighborhood drainage can flood homes with little warning.

Home prep before the event

Before heavy rain, check the FEMA flood map, photograph contents, lift stored items, test sump pumps, add battery backup where practical, clean drains, extend downspouts, and ask whether the sewer line needs a backwater valve. Keep flood insurance documents separate from standard homeowners coverage.

During-event safety

During flooding, move up, not out through water. Do not drive across covered roads, enter a flooded basement with energized circuits, or run pumps if the discharge adds water against the foundation. Follow local evacuation and boil-water notices.

Post-event recovery

After floodwater recedes, do not start demolition until photos, high-water marks, and insurer instructions are recorded. Standard homeowners policies usually exclude flood; use NFIP or private flood coverage if you have it. Substantial-damage letters can trigger elevation or repair limits. Use FEMA's AZ page at https://www.fema.gov/locations/arizona if a federal disaster is declared, and monitor Arizona Department of Emergency and Military Affairs at https://dema.az.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.

Code references

Code reference: mapped flood work depends on FEMA Flood Insurance Rate Maps at https://msc.fema.gov/portal/home, local floodplain ordinances, NFIP substantial-damage rules, IRC R322/IBC 1612 where adopted, and ASCE 24 guidance at https://www.fema.gov/node/american-society-civil-engineers-flood-resistant-design-and-construction.

Extreme heat / heat domes

Risk profile

Arizona heat domes can keep overnight temperatures dangerously high, stressing AC equipment, attic ducts, roof surfaces, and medically vulnerable residents.

Home prep before the event

Before peak heat, service AC equipment, replace filters, clear condenser airflow, seal major attic leaks, shade west-facing glass where practical, and plan a cooling location for outages. Confirm generator and transfer equipment are permitted and never run portable generators indoors or in garages.

During-event safety

During extreme heat, treat indoor temperature as a safety condition. Move vulnerable residents to cooling centers if the home will not cool, drink water, avoid oven use, and call 911 for confusion, fainting, or suspected heat stroke.

Post-event recovery

After a heat event, document AC failure, electrical damage, spoiled medicine, and any emergency lodging or cooling costs. Check utility, LIHEAP, weatherization, and local repair-assistance programs before replacing equipment, and keep medical or outage notices with the claim file. Use FEMA's AZ page at https://www.fema.gov/locations/arizona if a federal disaster is declared, and monitor Arizona Department of Emergency and Military Affairs at https://dema.az.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.

Code references

Code reference: heat resilience upgrades are typically governed by local mechanical, electrical, and energy codes, including adopted IECC or ASHRAE 90.1 provisions. Generator interlocks, transfer switches, and new circuits require NEC-compliant permitted work.

Plan the repair before the next warning

Use this guide to prioritize inspections, then compare licensed local contractors before the emergency queue fills after the next storm, freeze, heat wave, flood, or fire.
