What Michigan does to a house
A state is a big place — these are the ranges, not averages. The county pages pin the numbers down.
- Climate
- Zones 4a–6b. Freezing days run from ~124 to ~195 a year depending on the county.
- First freeze
- Usually lands anywhere from September 25 to October 25 depending on the county.
- The air
- Runs from temperate to humid, county by county.
- The load
- Heating season rules the calendar in most of the state.
- Termites
- Low pressure as a state band.
- Radon
- EPA Zone 2 — the middle band — statewide. A one-time test settles it either way.
- Labor
- Labor sits near one level statewide — every price band on this site adjusts to the county anyway.
