Do You Need a Permit to Build or Replace a Deck in Marietta, GA?

What the City of Marietta Says About Deck Permits

The City of Marietta’s Building Permits page lists decks—“new, repair, or replace”—as examples of work that requires a permit. The city also explains that permits apply when an owner or contractor constructs, enlarges, alters, repairs, moves, or demolishes a building or structure.

That makes it important to ask before assuming a small repair is exempt. Replacing a few surface boards may be treated differently from altering framing, stairs, guards, footings, or the house connection, but the permitting authority—not the homeowner or contractor—makes that determination.

First Confirm Which Jurisdiction Controls the Property

“Marietta” can describe a postal address, a city, or a broader local area. Some Marietta-address properties are inside city limits, while others are in unincorporated Cobb County. Nearby municipalities have separate building departments.

Cobb County’s residential permitting page directs property owners to determine jurisdiction before beginning the county process. This matters because the application portal, fee schedule, adopted amendments, inspection scheduling, and required forms may differ.

1. Confirm whether the parcel is inside an incorporated city.
2. Use the building department serving that jurisdiction.
3. Describe the complete scope, including demolition, repair, replacement, roof work, and electrical features.
4. Ask which permit type, drawings, and inspections apply.

Deck Projects That Commonly Need Review

New decks and complete replacements are the clearest examples. Other work may require review when it changes a structural or safety component.

• Changing posts, beams, joists, footings, or the ledger
• Building or significantly altering stairs and landings
• Replacing or changing guardrail systems
• Expanding the footprint or changing the deck height
• Adding a roof, covered porch, pergola, or enclosure
• Adding electrical circuits, receptacles, fans, or permanent lighting
• Adding heavy features or changing how the structure is loaded

Even when the final surface looks similar, altering the supporting structure can trigger plan and inspection requirements.

What Documents May Be Needed

The City of Marietta currently explains that residential construction plans should show a detailed scope and scaled, dimensioned drawings. For exterior work involving land disturbance, a site plan may also be required. Contractor license and business information may be part of the application.

A deck submittal may need to communicate:

• Property lines, existing structures, and proposed deck location
• Deck dimensions, height, stairs, and distance from lot lines
• Footings, posts, beams, joists, ledger or freestanding design
• Guardrails, handrails, landings, and connections
• Material specifications and manufacturer details where relevant
• Roof loads, electrical scope, or engineered details for non-prescriptive designs

Projects that add loads to an existing structure or use engineered designs may require a design professional. Ask the permitting office what applies before finalizing plans.

Why Required Deck Inspections Matter

Inspections allow critical work to be reviewed at stages when it is visible. Depending on the project, that can include footings before concrete is covered, framing and connections before decking conceals them, and a final inspection of guards, stairs, handrails, and the completed structure.

A permit is not simply paperwork added at the end. Beginning without required approval can lead to delays, opened-up work, corrections, difficulties during a sale, or questions from an insurer or future buyer.

The American Wood Council’s prescriptive deck guide repeatedly notes that local requirements and the authority having jurisdiction control. A national guide is useful background, but it does not replace the locally adopted code and approved plans.

HOA Approval and Contractor Responsibility

Homeowners association approval and a building permit are different. An HOA may regulate appearance, placement, color, or submittal procedures, while the building department addresses zoning, construction, and inspections. Receiving one approval does not automatically provide the other.

Before hiring a deck contractor, ask who will prepare drawings, submit the application, pay permit fees, respond to corrections, schedule inspections, and retain final documentation. These responsibilities should be clear in the written scope.
