What goes wrong under Kennesaw houses

- City versus unincorporated Cobb jurisdiction confusion
The Kennesaw pattern
Kennesaw's crawl spaces are young by metro standards, which changes what we find. Structural failure is rare here. What we do find is a 6-mil polyethylene sheet that was correct in 1998 and has since been torn open by twenty years of HVAC technicians, plumbers and pest control operators crawling across it. A barrier with a dozen unsealed tears is not a vapor retarder, and that single condition explains most Kennesaw humidity complaints.

Kennesaw housing stock and foundations
Large-scale subdivisions from the 1990s and 2000s Cobb growth wave, on poured and block stem-wall crawl spaces with generous clearance, standard fiberglass batting, and 6-mil polyethylene on the soil.
Newer stem-wall construction with good access, which makes Kennesaw among the fastest cities in the metro to encapsulate and among the least likely to need structural repair.
Soil: Cecil and Madison clay loam on the Kennesaw Mountain and Noonday Creek drainage divides.
Permits in Kennesaw
Structural crawl space work in Kennesaw, meaning joists, girders, sill plates and piers, requires a residential building permit and a framing inspection. Encapsulation, vapor barrier, insulation and cleanout work does not, though a dedicated dehumidifier or sump pump circuit needs an electrical permit.
Kennesaw city limits are irregular, and many 30144 and 30152 addresses are unincorporated Cobb County permitting through Cobb Community Development. Verify by parcel, not by mailing address, before filing a structural crawl space permit.

Noonday Creek and Proctor Creek in Cobb. Subdivision detention built to 1990s standards is the recurring issue where downhill homes sit below an outfall. Northwest Cobb runs cooler at night than the urban core, extending the spring and fall condensation window in vented crawl spaces.
