About 78% of Coweta homes are owner-occupied (Census), well above the metro average. Owners who plan to stay are the ones who benefit most from a sealed attic and crawl space.
Newnan and Senoia are dominated by subdivisions from the 2000s; the rest of the county has farms, barns and metal shops where closed-cell spray foam is the usual answer.
The whole county is zone 3A: R-38 ceilings (R-30 at full depth over the plates), R-13 walls and R-13 or R-5 continuous on unvented crawl space walls.
Newnan permits work inside city limits through its Building Department. Other addresses go through their own city or Coweta County, and we confirm the right office for yours.
