Insurance Market Context
These scores are county-level composites derived from FEMA National Risk Index. Individual parcels may differ significantly. This is not a property appraisal.
Insurance market data for Arizona is band-only in the free snapshot. The full report includes admitted-carrier share, YoY exit rate, and the FAIR Plan / Citizens last-resort premium range.

Premium Strain Index
Band: elevated· specific % in $19 report
Premium-to-income ratio. Based on state Department of Insurance filings, average annual premiums in this area range from $1,500 to $3,200. Not an insurance quote. The First Street 12th National Risk Assessment characterizes any ZIP above 5% as financially unsustainable.
Maricopa County Hazard Breakdown

Editorial Analysis
Phoenix's heat score of 96 sits at the 99th national percentile—the highest heat ranking in this entire dataset—and the 2023 record-breaking summer produced 31 consecutive days above 110°F, extending cooling-system dependence and grid-reliability risk into a duration that previous planning models had not assumed. Phoenix is the clearest US example of a market where climate cost is primarily expressed through utility bills, cooling infrastructure investment, and long-term habitability assumptions rather than through insurance premium shock. The 2014 monsoon flash flooding demonstrated the secondary hazard: Valley washes and drainage channels fill rapidly under intense monsoon rainfall despite the desert setting. What we noticed: heat-island intensity peaks in Downtown Phoenix's 85003 zip code, where asphalt density and limited tree canopy produce overnight temperatures materially higher than the metro average. North Phoenix's 85054 carries both wildland-edge exposure and water-constraint considerations that the urban core does not share. Premium Arcadia and Biltmore fringe housing in 85018 faces the same extreme heat exposure as every other Phoenix neighborhood; lot price does not modify ambient temperature. Annual premiums range from $1,500 to $3,200—moderate—because the dominant Phoenix climate cost is operational rather than insurance-driven. Cooling costs and outage resilience are the real variables: summer electricity bills during a 2023-style heat season can exceed monthly mortgage payments in older, less-efficient homes. Wildland-edge neighborhoods see added underwriting scrutiny. Flood at the 47th national percentile is low but not zero—wash-adjacent parcels deserve review. Phoenix demands a heat-resilience framework. The traditional insurance-premium metric dramatically underprices the actual risk burden in this market.
