All Home Additions·All Services in Kennesaw

Kennesaw homeowners who love their established neighborhoods — particularly the quieter streets around Kennesaw Mountain National Battlefield and the Stilesboro Road area — are choosing additions over relocating to newer construction farther out. The 1980s and 1990s framing on these homes is solid and ties in well, but the older roof and exterior materials often need to be addressed as part of the addition scope.

Cobb County permitting covers Kennesaw, and we're experienced with the county's review process and inspection sequence for addition projects — which helps prevent the delays that can extend timelines on structural work.

Frequently Asked Questions

How long does a addition project take in Kennesaw?

Home additions typically take 4–6 months from permit approval to final inspection. Permit and plan review in Cobb and Cherokee counties adds 6–10 weeks before construction begins — we factor this into the overall timeline from day one.

Kennesaw homes from the 1980s and 1990s are common in our neighborhood — what conditions do contractors typically find behind the walls?

The 1980s and 1990s construction in Kennesaw was solid, but at 30–40 years old, you're likely to find original plumbing (occasionally polybutylene), aluminum branch wiring in some homes, and HVAC systems that have been repaired but not replaced. We assess all of these during our initial walkthrough and flag anything that should be addressed alongside your renovation scope.

Yes — we handle all permitting for projects in Cobb County. We prepare the documentation, submit the application, schedule all required inspections, and keep you informed at each stage. You don't need to manage the permit process — that's part of what you're hiring us to do.
