General Contractor
in Marietta, GA
Marietta is the Cobb County seat — a city of 64,000 anchored by Lockheed Martin's F-35 and C-130J plant, WellStar Kennestone Hospital (busiest ER in Georgia), Dobbins Air Reserve Base, and the historic Marietta Square. Home prices span $300K in West Marietta to $550K+ in East Cobb, with dual permit jurisdictions — City of Marietta inside city limits, Cobb County elsewhere. BCG navigates both every week.
Construction Market in Marietta
Marietta's construction market splits cleanly into three zones that each demand a different approach. The Marietta Square and surrounding Historic District bring design review requirements, preservation overlays, and pre-1940 structures that need careful renovation. East Cobb — Walton, Wheeler, and Lassiter school zones — is where $500K+ custom homes and whole-home remodels cluster on larger lots. The Kennestone Hospital corridor along Church Street and Cobb Parkway drives the medical office and healthcare TI pipeline. BCG pulls permits through both the City of Marietta and Cobb County Community Development, and we know which jurisdiction applies to which address.
Kennestone Corridor — Medical Office & Healthcare TI
WellStar Kennestone is a 633-bed Level II trauma center with the busiest ER in Georgia, and WellStar's system HQ is in Marietta. That generates consistent demand for medical office build-outs, specialty clinics, and healthcare TI along Church Street, Cobb Parkway, and the Tower Road corridor. BCG handles negative pressure, medical gas, and lead-lined construction for these scopes.
Medical TI — $300–$600+/SFEast Cobb — $500K+ Custom Homes & Renovations
East Cobb zip codes 30062, 30066, and 30068 anchor the city's premium residential market. Walton, Wheeler, and Lassiter high schools drive family demand. Homes routinely comp at $550K–$850K. Whole-home renovations, master suite additions, and custom rebuilds on teardown lots are the dominant scopes — and buyers expect premium finish levels calibrated to the neighborhood.
East Cobb — $550K–$850K compsThe Square & Historic District — Design Review
Projects within Marietta's Historic District and around the Square trigger Historic Preservation Commission review. Material selection, window proportions, and setback conformance matter. BCG has built through this process — restaurant build-outs, boutique retail TI, and historic home renovations along Church, Cherokee, and Whitlock.
HPC review — pre-1940 structuresLockheed & Dobbins — Defense Adjacency & Sound Contours
Lockheed Martin's Marietta plant employs 8,000+ on F-35 and C-130J production. Dobbins Air Reserve Base shares the runway. Residential and commercial construction inside the airport noise contour (AICUZ zones) faces sound attenuation requirements and HVAC isolation specs. BCG factors these into pre-design for any project in South Marietta or along Cobb Parkway near the base.

It depends on the address. Properties inside the Marietta city limits are permitted by the City of Marietta Building Department. Properties in unincorporated Cobb County (but with a Marietta mailing address) are permitted by Cobb County Community Development. BCG confirms jurisdiction at the start of every project and submits to the correct office.
Construction, exterior modification, and significant renovation within Marietta's Historic District triggers Historic Preservation Commission review in addition to the standard building permit. The HPC evaluates material selection, window proportions, porch details, and setback conformance. BCG has walked projects through this review — including Certificate of Appropriateness submittals — on restaurant, retail, and residential work around the Square.
Costs vary by project type and zone. Custom homes in East Cobb run $200–$400+ per square foot depending on finish level. Whole-home renovations are typically $150–$350 per square foot. Medical office TI near Kennestone runs $300–$600+ per square foot with the specialty MEP requirements (medical gas, negative pressure, lead shielding). We provide detailed line-item estimates within 48 hours.
Yes. Projects within the Dobbins AICUZ noise contour zones face sound attenuation and HVAC isolation requirements above baseline Cobb County code. BCG addresses these specifications at pre-design, not as a correction cycle, and we coordinate with Cobb County on any AICUZ-impacted plan reviews.
