Illinois Home Insurance

Illinois home insurance rates, Chicago vs downstate pricing, and the realities of severe weather and aging housing stock.

  • State: Illinois (IL)
  • Avg annual rate: $1,410

Illinois has homeowners insurance premiums close to the national average at about $1,410/year. Tornado and severe thunderstorm activity in central and southern Illinois drive premiums up; northern Illinois and the Chicago metro have lower but still meaningful storm exposure.

Average rates

By region:

  • Chicago metro: $1,500-$2,200/year
  • Suburbs (Naperville, Schaumburg): $1,300-$1,800/year
  • Central Illinois (Springfield, Peoria): $1,100-$1,500/year
  • Southern Illinois (tornado alley extension): $1,300-$1,900/year
  • Rural northern: $900-$1,300/year

Key risks

Tornadoes: Illinois averages 50+ tornadoes per year, with the highest frequency in central and southern counties. Wind damage from severe thunderstorms is the most frequent claim category statewide.

Flooding: Both river flooding (Mississippi, Illinois, Rock rivers) and urban flash flooding in Chicago. Standard policies exclude flood — get separate NFIP or private flood coverage if you’re in a flood plain or below grade.

Sewer backup: Chicago’s combined sewer system makes water-in-basement claims one of the most frequent in the city. Sewer/water backup endorsement is essential here ($50-$150/year, often required by lenders).

Aging housing: Chicago has substantial pre-1940 housing stock. Knob-and-tube wiring, old plumbing, and asbestos siding can affect underwriting.
