Market guide ranges, October 2026 — published Atlanta/Marietta sources and Remodeling Magazine Cost vs. Value 2025 (Atlanta), reconciled in our research. These are planning ranges, not a quote for your home; your written scope sets your price.
Published Atlanta and Marietta prices for the same job differ by 2–3× depending on who publishes them. We reconcile the three anchors in the open — Remodeling Magazine's Cost vs. Value 2025 (Atlanta), local contractor ranges, and lead-gen averages — and date every figure. Midrange kitchen: $50,000–$65,000 (metro Atlanta guide) to $79,591 (Cost vs. Value). Midrange bath: $25,304. Basement finishing: $30–$95 per square foot.

City or County? The Marietta permit trap
A Marietta mailing address is not a permit jurisdiction. Inside city limits, permits run through SagesGov; most of East and West Cobb is unincorporated county. Historic addresses can add a Certificate of Appropriateness — Kennesaw Avenue's COA is decided within 45 days and no permit issues without it. Start with the permit navigator and the Kennesaw Avenue COA guide.
Built for Cobb County's housing stock
Cobb's median home was built in 1989. The 1970s–1990s stock now needs kitchens, primary baths and systems together — including polybutylene supply piping in 1978–1995 homes. We surface systems in the estimate, in the order set out on the whole-home renovation page, so demo day holds fewer surprises.
