The median sale price for homes in Marietta over the last 12 months is $485,000, up 2% year-over-year — a signal of steady appreciation and sustained demand that shows no signs of softening. This guide walks you through everything you need to know about building new in Marietta, from choosing a community to picking up your keys.

Why Marietta, GA Is a Smart Place to Build New

Location, Lifestyle, and Community

Marietta sits in the heart of Cobb County, roughly 15 miles northwest of Atlanta — an ideal base for buyers who want suburban quality of life without sacrificing city proximity. The distances speak for themselves:

• 10 minutes to the trails at Kennesaw Mountain National Battlefield Park
• 15 minutes to The Battery Atlanta and Truist Park
• 30 minutes to downtown Atlanta
• 40 minutes to Hartsfield-Jackson for frequent travelers

Day-to-day life centers around the historic Marietta Square, where residents gather at Glover Park for the free Glover Park Concert Series and browse Georgia-grown goods at the Saturday Marietta Square Farmers Market. The Marietta Square Market Food Hall draws locals for lunch with its 19-plus eatery options inside a revitalized warehouse. And the Earl and Rachel Smith Strand Theatre — a beautifully restored 1935 Art Deco venue — hosts more than 200 events annually, from live performances to classic films.

Schools and Education

Marietta's school options are a genuine draw for families relocating to the area. The City of Marietta operates its own independent Marietta City Schools district, one of Georgia's first Charter Systems and an International Baccalaureate World School district. Families in surrounding unincorporated areas are served by the Cobb County School District — the second-largest in Georgia.

105,738 students across 112 schools are served by the Cobb County School District, and its high schools score 4.7 points above the Georgia state average.

In 2024, U.S. News ranked Walton High School fourth in Georgia among public high schools, with Lassiter at No. 12 and Pope at No. 25. Private options are also strong — The Walker School on Cobb Parkway has been named Best Private K-12 in Cobb County by Niche.

Why New Construction Makes Sense Here

The case for building new in Marietta goes well beyond wanting something shiny. New homes come with 10-year structural warranties and modern building codes, meaning buyers avoid the first-year surprises that older resale homes often carry — think HVAC replacements or outdated plumbing. In Georgia's humid climate, modern moisture barriers and high-efficiency insulation aren't nice extras; they're essential for long-term home health and lower energy bills.

948 homes are currently for sale in Marietta, up 16.3% from last year — with 267 new listings in the last 30 days alone, an 11.3% year-over-year increase.

Homes here sell in an average of 40 days, compared to the national average of 58 — a clear signal that buyer demand remains strong.  Meanwhile, Cobb County led all large Georgia counties in employment growth from September 2024 to September 2025, posting job gains of 0.9% — the strongest of any large county in the state.

Choosing the Right Community and Builder in Marietta

Active New Construction Communities to Know

Marietta's new construction landscape spans townhomes, single-family homes, gated communities, and large planned developments — giving buyers at different budgets real range to explore. Here's a snapshot of key communities actively building now:

• Bluffs at Bells Ferry — Built by Traton Homes near Cobb Parkway and I-75, featuring stylish two-story townhomes including the award-winning Brooks floor plan, with convenient access to major shopping and dining corridors.
• Ellis Marietta — A large planned community with homes from several top Cobb County builders, positioned close to Kennesaw Mountain National Battlefield Park and downtown Marietta.
• Village at Sandy Plains — East Cobb's newest gated community, showcasing contemporary style and functionality for buyers drawn to that corridor.
• Hampton Trace — 80 townhomes with three-story contemporary residences and open-concept layouts built for modern living.
• Kirkview and Millwood Farms — Both by Paran Homes, offering three-to-six bedroom floor plans from the mid $500s with easy access to I-75.

Top Builders Operating in Marietta

The Marietta market is served by a diverse roster of builders, each with distinct strengths. Active builders include D.R. Horton, Toll Brothers, Traton Homes, David Weekley Homes, Bercher Homes, Davidson Homes, and Paran Homes. Production builders like D.R. Horton offer faster timelines and streamlined packages; semi-custom builders like David Weekley and Toll Brothers allow more personalization at a higher price point.

Most new homes in Marietta start around $400,000, with luxury options extending well above $1 million depending on the community, builder, and finishes selected. Before committing to a builder, tour model homes, compare warranty structures, review upgrade packages, and understand HOA fee structures — these details meaningfully affect total cost of ownership.

Questions to Ask Your Builder Before Signing

Going into a builder conversation prepared makes a real difference. Raise these questions before you sign anything:

• What is the estimated construction timeline from contract to close?
• What does the structural warranty cover and for how long?
• Are there preferred lender requirements, and what incentives come with using them?
• When is the upgrade cut-off date after which no design changes are permitted?
• What HOA fees apply, and what do they cover?

Getting clear answers upfront prevents costly misunderstandings later in the process, when options narrow considerably.

Understanding Permits and Approvals in Marietta and Cobb County

City of Marietta vs. Cobb County Jurisdiction

One of the most important details buyers and builders must nail down early: jurisdiction. The permitting authority that governs a new construction project depends entirely on where the property sits. Homes inside Marietta city limits fall under the City of Marietta's Building Permits and Inspections office. Homes outside city limits — in unincorporated Cobb County — fall under Cobb County Community Development. These are two entirely separate systems with different processes, fee schedules, and inspection workflows.

Verify your lot's jurisdiction before signing any paperwork. Builders operating in both jurisdictions are typically familiar with both sets of requirements, but buyers who understand the distinction ask sharper questions and avoid surprises.

💡 Pro Tip: Ask your builder to confirm in writing which jurisdiction governs your specific lot. This single step can prevent weeks of confusion during the permitting phase.

What Permits Are Required for New Construction

In both jurisdictions, a permit is required whenever an owner or contractor intends to construct a new building, enlarge, alter, repair, move, or demolish a structure, or install or alter any electrical, gas, mechanical, or plumbing system. Site development and utility construction also require permits. That means a new home build will involve multiple permit applications and separate inspections at each trade stage.

Cobb County's Community Development Agency coordinates permitting across several departments: Development and Inspections reviews plans and conducts stage-by-stage inspections; the Planning Division ensures projects comply with zoning laws; the Zoning Division handles zoning permits and variances; and the Business License Division issues licenses for contractors.

Permit Costs and Timelines

Effective July 1, 2024, Cobb County updated its residential permit fee structure in alignment with House Bill 461. New construction permit fees are now calculated at $6.00 per $1,000 of estimated construction cost, based on the International Code Council Building Valuation Data — a shift from earlier job-cost-based calculations toward a square footage and fixed-rate formula.

Inspection turnaround is generally efficient. Requests submitted by 4:00 PM are typically scheduled for the next business day. Your builder will manage the permitting process on your behalf, but understanding these timelines helps set realistic expectations for how long each construction phase takes to clear before work can continue.

The New Home Construction Process — Phase by Phase

Phase 1 — Pre-Construction and Design

The process begins with lot selection, floor plan choice, and a design center appointment. This is where buyers select finishes, cabinetry, countertops, flooring, fixtures, and appliances — and where "upgrade creep" becomes a real budget risk. It's easy to add $50,000 or more in selections without fully tracking the cumulative cost. Set a firm design center budget before you walk in.

After the design center, the construction contract is reviewed and signed. Buyers should carefully review builder draw schedules, financing requirements, and any clauses around price adjustments due to material costs before executing the agreement.

💡 Pro Tip: Bring a detailed spreadsheet to your design center appointment with every category itemized and a max spend per line. Builders' design centers are built to inspire — a budget guardrail keeps you grounded.

Phase 2 — Foundation and Framing

Once permits are in hand, site work begins: land clearing, grading, and the foundation pour. Framing follows, along with roofing and exterior sheathing — this is the stage where the home goes from a flat lot to a recognizable structure. Many builders offer a framing walk-through with their project manager at this point. Take advantage of it every time.

Phase 3 — Mechanical Rough-In and Inspections

With framing complete, electrical, plumbing, and HVAC systems are roughed in — each requiring separate permits and inspections in both City of Marietta and Cobb County jurisdictions. The Development and Inspections division reviews each stage before walls are closed, ensuring code compliance before insulation and drywall are installed.

This stage is critical. Once the walls close, access to these systems becomes significantly more difficult and expensive to address.

Phase 4 — Interior Finishes and Final Inspections

This is the stage most buyers look forward to. Flooring goes down, cabinetry and countertops are installed, fixtures are hung, and paint is applied. Final inspections culminate in the issuance of a Certificate of Occupancy — the legal authorization to move in. Before closing, buyers conduct a pre-closing "blue tape" walkthrough with the builder to document punch-list items that need correction.

Phase 5 — Closing and Move-In

Even with new construction, hire an independent home inspector for the pre-closing walkthrough. A builder's internal inspection is not a substitute for an objective, third-party review. Final loan approval and closing follow, with the builder handing over keys and full warranty documentation. Depending on the builder, floor plan complexity, and permitting timelines, construction in the Marietta market generally runs 6 to 14 months from contract to close.

Financing a New Construction Home in Marietta

Builder Financing vs. Independent Lenders

Most Marietta builders have a preferred lender, and they often incentivize buyers to use them through closing cost credits or rate buy-down programs — which can be genuinely valuable. That said, compare builder-preferred lender terms against independent financing options before committing. The incentive doesn't always translate to the best overall loan structure for every buyer's situation.

Managing Upgrade Costs and Appraisals

New construction appraisals can sometimes come in below the contract price when comparable sales in a new community are limited. Buyers should understand how this affects their financing — specifically, whether their loan requires the appraisal to meet the contract price, and what options exist if there's a gap. Planning for this scenario early prevents a stressful surprise in the weeks before closing.

Rate Lock Strategy on a Long Build

A 6-to-14-month build timeline means interest rates can shift significantly between contract execution and the closing table. Discuss rate lock options with your lender early — extended rate lock programs exist but often carry a cost that should be factored into the overall financing comparison.

Life After Move-In — What Marietta New Homeowners Should Know

Warranty Coverage Essentials

Standard new construction warranties in the Marietta market follow a tiered structure:

• 1 year covering workmanship
• 2 years covering major systems including HVAC, plumbing, and electrical
• 10 years covering structural components

Document every issue you notice during the first year of occupancy and submit warranty claims well before the one-year mark. In Georgia's humid climate, early documentation of any moisture-related concerns is especially important — don't wait.

HOA Life in Marietta's New Communities

Most new construction communities in Marietta include homeowners associations that govern exterior maintenance standards, common areas, and amenity access. Many offer swimming pools, walking paths, playgrounds, and clubhouses — amenities that add real lifestyle value but also translate to monthly HOA dues. Request and carefully review the CC&Rs, bylaws, and HOA financial disclosures before closing. These documents govern life in your community long after move-in day.

Getting to Know Your New Neighborhood

Marietta rewards residents who get involved. Glover Park hosts free outdoor concerts throughout the summer and fall, and the Marietta Square Farmers Market runs Saturdays and Sundays year-round for fresh Georgia produce and local artisan goods. Families should initiate school registration with either Marietta City Schools or the Cobb County School District as early as possible, since enrollment timelines vary by grade level and school. For shopping, Town Center at Cobb off I-75 and I-575 serves the broader Marietta and Kennesaw area with major retail and dining options.

Frequently Asked Questions About Building a New Home in Marietta, GA

How long does it take to build a new home in Marietta?

Typical timelines range from 6 to 14 months depending on the builder, floor plan complexity, and how quickly permits move through the City of Marietta or Cobb County. Production builders like D.R. Horton tend to operate on the shorter end of that range, while semi-custom or custom builders take longer. Ask any builder you're considering for their recent average completion times on comparable projects.

Do I need my own real estate agent when buying new construction?

Yes — and it matters more than many buyers realize. The builder's on-site sales agent represents the builder, not you. An independent buyer's agent can help negotiate upgrades, review the construction contract, coordinate independent inspections, and advocate for your interests throughout the process. This typically costs you nothing, since builder-paid commissions are standard.

What is the difference between building inside Marietta city limits and in unincorporated Cobb County?

The permitting authority, inspection process, and some code requirements differ between the two jurisdictions. Marietta's permitting rules apply inside city limits only; properties outside fall under Cobb County Community Development. Verifying your lot's jurisdiction before signing anything ensures you understand whose rules govern your build and what to expect from the approval process.

Can I make changes to my home after signing a contract?

Most production builders allow a limited structural change window shortly after contract execution — often 30 days or less. Design center selections, such as finishes and fixtures, are typically made within 30 to 60 days of signing. Once framing begins, major changes are rarely permitted, and those that are approved often carry significant cost premiums. Finalize decisions early.

What schools will my children attend if I build in Marietta?

School assignment depends on your specific address. Homes inside Marietta city limits are served by the independent Marietta City Schools district — an International Baccalaureate Charter System. Homes in unincorporated Cobb County fall within the Cobb County School District, which serves over 105,000 students and includes nationally ranked schools like Walton and Lassiter high schools. Always confirm school assignments directly with the relevant district using your lot address.

Is new construction in Marietta a good investment?

The fundamentals support it. The median property value in Marietta reached $448,500 in 2024, up 11.8% from $401,100 the prior year — and sits 1.35 times above the national median. Combined with Cobb County's employment growth leadership among Georgia's large counties, top-ranked school systems, and the long-term cost advantages of energy-efficient new construction, Marietta presents a compelling case for buyers ready to put down roots.

The Bottom Line

Building a new home in Marietta means entering one of metro Atlanta's most dynamic and livable communities, with a range of builders, neighborhoods, and price points that genuinely serve a wide spectrum of buyers. The process has real moving parts — navigating city versus county permitting, managing design center decisions, aligning financing timelines, and preparing for your final walkthrough.
