Franklin County homes, by the numbers
The typical home in Franklin County was built in 1979. Ohio's median is 1970. 25.4% went up before 1960. Newer homes usually have some insulation, but ENERGY STAR says 9 out of 10 U.S. homes are under-insulated [2], and crawl space insulation is often the first thing to fall.
When was your house built? The Franklin County Auditor's property search [3] lists the year built for most homes. Look up your address and tell us when you call; the age of the house tells us a lot about what is in the walls and attic.

Climate zone and the attic target
Under Ohio's residential code, Franklin County is in climate zone 5A [5]. The 2021 and 2024 model energy codes moved it to zone 4A [6], but Ohio has not adopted them. Either way, the attic advice is the same: ENERGY STAR recommends R-60 in an uninsulated attic and adding R-49 where there are already 3 to 4 inches, for zones 4 and 5 alike [7]. What that means for your attic.
