How bathroom remodel permits work in Marietta
Any bathroom remodel involving plumbing relocation, new electrical circuits, or structural wall changes requires a permit from Marietta Building and Zoning. Purely cosmetic work (paint, vanity swap without plumbing move, toilet-seat replacement) is exempt. The permit itself is typically called the Residential Building Permit (with sub-permits for Electrical and Plumbing as applicable).
Most bathroom remodel projects in Marietta pull multiple trade permits — typically building, electrical, and plumbing. Each is reviewed and inspected separately, which means more checkpoints, more fees, and more coordination between the trades on the job.
Why bathroom remodel permits look the way they do in Marietta
Marietta's Historic Preservation Commission requires a Certificate of Appropriateness for any exterior work in the Marietta Square historic district, adding review time beyond standard permits. Cobb County red clay soils require engineered footings and soil reports on many new construction and addition permits. The city operates its own water/sewer utility (Marietta Water) independent of Cobb County Water, affecting tap fees and connection permit routing.
Natural hazard overlays in this jurisdiction include tornado, FEMA flood zones, expansive soil, and radon. If your address falls within any of these overlay zones, the bathroom remodel permit application picks up an extra review step that can add days to the timeline and specific design requirements to the plans.
Marietta has a designated Historic District centered on the Marietta Square (downtown); the Historic Preservation Commission reviews exterior changes, demolitions, and new construction within the district. The Root House and surrounding antebellum streetscape are especially regulated.
What a bathroom remodel permit costs in Marietta
Permit fees for bathroom remodel work in Marietta typically run $150 to $600. Valuation-based; typically a percentage of declared project value plus separate flat fees for each trade sub-permit (electrical, plumbing)
A state mandated Georgia DCA fee surcharge (typically 8% of permit fee) is added to all permits; plan review fee may be charged separately if drawings are required.
The fee schedule isn't usually what makes bathroom remodel permits expensive in Marietta. The real cost variables are situational. Galvanized supply line and cast-iron stack replacement in 1950s–1970s homes frequently discovered mid-demo, adding $4,000–$9,000 in unplanned replumb costs. Georgia's split trade-licensing system requires separately hired and insured plumbing and electrical subs, each with their own permit — increasing soft costs vs markets with licensed GCs covering all trades. EPA RRP lead-paint compliance in pre-1978 homes (common near Marietta Square) adds certified renovator fees and proper disposal costs. Red clay expansive soil in Marietta can cause slab movement, meaning relocated first-floor bathroom drains may require concrete cutting and re-sloping at significant additional cost.
How long bathroom remodel permit review takes in Marietta
3-7 business days for standard review; simple scope may be over-the-counter same day. There is no formal express path for bathroom remodel projects in Marietta — every application gets full plan review.
What lengthens bathroom remodel reviews most often in Marietta isn't department slowness — it's resubmissions. Each correction round generally puts the application back in the queue, so first-pass completeness matters more than first-pass speed.
The best time of year to file a bathroom remodel permit in Marietta
CZ3A Marietta is workable year-round for interior bathroom remodels; spring (March–May) and fall (September–October) are peak contractor seasons with 2–4 week longer lead times for licensed subs, so scheduling in January–February typically yields faster sub availability and potentially quicker inspection turnaround.
Documents you submit with the application
A complete bathroom remodel permit submission in Marietta requires the items listed below. Counter staff perform a completeness check at intake; missing anything means the package is not accepted and the timeline does not start.
- Completed permit application with declared project value and scope description
- Floor plan or sketch showing existing and proposed fixture locations (dimensioned)
- Electrical plan showing new circuits, GFCI/AFCI locations, and panel schedule if circuit added
- Contractor license numbers and insurance certificates for each licensed trade sub (plumber, electrician)
Who is allowed to pull the permit
Homeowner on owner-occupied primary residence may pull the building permit; licensed state-board subs must pull their own trade permits (electrical sub pulls electrical permit, plumber pulls plumbing permit)
Georgia State Licensing Board for Residential and General Contractors (plumbing): state plumber's license required. Georgia State Electrical Contractors Board: state electrical contractor license required. Both must hold a City of Marietta local business license and show proof of liability and workers' comp insurance.
What inspectors actually check on a bathroom remodel job
For bathroom remodel work in Marietta, expect 4 distinct inspection stages. The table below shows what each inspector evaluates. Failed inspections add typically 5-10 days to the total project timeline plus the re-inspection fee.
| Inspection stage | What the inspector checks |
|---|---|
| Rough Plumbing | Drain, waste, and vent (DWV) pipe sizing and slope; trap arm lengths; vent stack connectivity; pressure test on supply lines; new fixture rough-in heights |
| Rough Electrical | New circuit wiring, box fill, GFCI/AFCI device placement, panel connection and labeling, exhaust fan circuit |
| Framing / Waterproofing | Any structural wall changes, shower pan liner or pre-slope, waterproofing membrane height (72" above drain), backer board installation before tile |
| Final | All fixture installations, vent fan operation and exterior termination, GFCI/AFCI devices functional, toilet flange at finished floor, pressure-balance valve installed, permit card posted |
A failed inspection in Marietta is documented on a correction notice that lists each item that needs to be fixed. The work cannot continue past that stage until the re-inspection passes, and on bathroom remodel jobs that often means leaving framing or rough-in work exposed for days while you wait.
The most common reasons applications get rejected here
The Marietta permit office sees the same patterns over and over. These specific issues account for most first-pass rejections, and most of them are entirely preventable with a few minutes of double-checking before submission.
- GFCI receptacles missing or improperly placed per 2020 NEC 210.8(A) — all bathroom receptacles require GFCI regardless of distance from water
- Vent fan undersized or terminating into attic rather than exterior (IRC R303.3 and M1505.4 require exterior exhaust)
- Shower waterproofing membrane not extending to 72" above drain or shower pan liner not properly sloped to drain flange (IRC R307.2)
- Pressure-balance or thermostatic mixing valve missing at shower/tub per IRC P2708.4
- Toilet flange set too low — must be flush to or up to 1/4" above finished tile floor
Mistakes homeowners commonly make on bathroom remodel permits in Marietta
Each of these is a real, recurring mistake on bathroom remodel projects in Marietta. They share a common root: applying generic permit advice or out-of-state experience to a city with its own specific rules.
- Assuming a homeowner permit covers all trade work — in Marietta, the licensed plumber and electrician must each pull their own separate trade permits, and homeowners cannot substitute their own labor for licensed trade rough-ins
- Starting demolition in pre-1978 homes without EPA RRP lead testing, which is required by federal law and can result in stop-work orders and fines
- Scheduling all inspections under one permit card, not realizing that plumbing and electrical rough-ins are inspected under separate trade permits on separate inspection queues
- Closing walls before all three rough-in inspections (plumbing, electrical, framing/waterproofing) are signed off — the most common cause of costly rework in Marietta bathroom projects
The specific codes that govern this work
If the inspector cites a code section, this is the list they'll most likely be referencing. These are the live code references that Marietta permits and inspections are evaluated against.

Georgia adopts the IRC with state amendments via the Georgia Department of Community Affairs (DCA); Marietta enforces the 2018 IRC and 2020 NEC. No major bathroom-specific local amendment confirmed beyond state DCA modifications, but verify current Georgia DCA amendments at time of permit application.
