Bathroom Remodel Permit in Carrollton, GA (2026)

Research by DoINeedAPermit Research Team · Updated May 2026

The Short Answer

A full bathroom remodel in Carrollton requires a permit if you relocate plumbing fixtures, add new electrical circuits, install a new exhaust fan, convert a tub to shower, or move any walls. Surface-only work (tile, vanity swap in place, faucet replacement) does not.

Carrollton Building Department enforces Georgia State Code and the current International Residential Code (2015 IRC or later adopted version) with no unusually strict local amendments — meaning your code obligations are similar to the surrounding Carroll County unincorporated area, but Carrollton's online permit portal and intake process differ significantly from county process. Carrollton's Building Department operates its own permitting system with separate fee schedules and plan-review timelines; you cannot pull a county permit for work inside city limits. The city typically accepts digital submissions through its online portal (verify current URL with the department) and processes standard bathroom remodels in 10–15 business days for plan review if electrical, plumbing, and framing scope are clearly documented. Georgia's state law (§ 43-4-6) allows owner-builders to pull permits for their own residence, but Carrollton requires standard plan packages (site plan, floor plan, electrical one-line, plumbing isometric, detail sheets for shower waterproofing) — contractor or owner, no shortcuts. The warm-humid climate (3A) and local Piedmont/Coastal Plain soil don't directly affect interior bathroom permits, but they do inform your HVAC duct termination and ensure proper exhaust fan sizing (IRC M1505 minimum 50 CFM for bathrooms ≤150 sq ft, plus 20 CFM per 150 sq ft additional).

What happens if you skip the permit (and you needed one)

Stop-work order and $500–$1,500 fine from Carrollton Building Department; unpermitted work must be removed or brought into compliance before certificate of occupancy.
Double permit fees ($600–$1,400 total) if you're caught mid-project and forced to retroactively pull the permit — plus reinspection costs.
Home sale disclosure requirement: Georgia law (O.C.G.A. § 44-3-2) requires seller to disclose unpermitted work on the Property Disclosure Statement; buyer can sue for damages or void the sale.
Insurance denial: Many homeowners' insurers deny claims if bathroom damage (e.g., mold from improper exhaust ducting) occurred in unpermitted work; some will drop coverage entirely.

Carrollton full bathroom remodel permits — the key details

Carrollton requires a permit for any bathroom remodel that includes fixture relocation (toilet, sink, tub/shower), new electrical circuits, new exhaust fan installation, or structural changes (walls, framing). The trigger is ANY of these, not all of them together. If you're replacing a toilet in its existing location with a new tank and bowl, no permit required — but if you're moving it 2 feet to a new drain location, permit required. The same logic applies to vanities: in-place cosmetic swap (remove old vanity, install new one on same wall, no plumbing changes) is exempt; but if you're moving the sink to the opposite wall or adding a second sink, you need a permit. The city's threshold aligns with Georgia State Code § 43-4-1 (residential construction), which defers to the International Residential Code for specific exemptions. Carrollton staff will ask you to identify the scope on the intake form: if you check 'moving fixtures' or 'new exhaust fan,' you're locked into the permit path — don't understate scope to avoid it, because inspectors will flag unpermitted work during final inspection or when a neighbor complains.

Electrical scope in a bathroom remodel is heavily regulated because bathrooms are wet locations. The National Electrical Code (NEC 210.52(D)) and IRC E3902 require all 120V receptacles within 6 feet of a sink, tub, or shower to be on a GFCI (ground-fault circuit interrupter) — either dedicated GFCI breakers or GFCI outlets. If your remodel adds new circuits (new exhaust fan motor, heated towel rail, additional lighting), those circuits must be shown on an electrical one-line diagram submitted with your permit application. Carrollton's plan-review staff will check that your electrical plan specifies GFCI protection, proper wire gauge for the circuit load, and conduit routing (exposed in unfinished spaces, concealed in walls). If you're adding a heated floor mat or radiant panel, that requires a dedicated circuit and specific NEC 424.44 labeling. Many homeowners hire a licensed electrician to design and install, then pull the permit on the work they've already specified — Carrollton allows this and actually expects it, because unlicensed DIY electrical work in a bathroom is high-risk. Budget $150–$400 for the electrical portion of your permit plan package (engineer or contractor-drafted); the permit fee itself is typically $75–$150 for electrical-only scope, but will be bundled with plumbing and structural fees if multiple trades are involved.

Plumbing changes in a bathroom remodel trigger IRC P2706 (drainage and venting) and IRC P2902 (water supply) requirements. If you're relocating a toilet, the drain line (called a trap arm) has code limits on horizontal run and must slope 1/4 inch per foot toward the main vent stack — Carrollton inspectors will verify this on rough plumbing inspection using a level and tape measure, and they will reject work if the slope is insufficient or the trap arm exceeds 6 feet (shorter if the vent is far away, per IRC P3101.1 calculation). If you're converting a tub to a walk-in shower or vice versa, the new assembly must be fully waterproofed per IRC R702.4.2 — specifically, a vapor barrier (cement board or equivalent) with a waterproof membrane (liquid or sheet) installed behind all tile and on the shower floor pan. Many Carrollton plan reviews fail on first submission because the applicant didn't specify the waterproofing system (e.g., 'Schluter-Kerdi system' or 'cement board + RedGard liquid membrane') — don't just say 'waterproof tiles'; specify the actual product and assembly. If you're adding a second sink or vessel sink, you'll need a new supply line (hot and cold, 1/2-inch minimum per IRC P2903.2) and a drain line (1-1/4 inch for a single sink, per IRC P3201.7). Exhaust fan ducting must be 4 inches diameter minimum (IRC M1505.2) and must terminate to the outdoors (not into the attic, not into a soffit) — this is a common code violation in existing homes, and Carrollton will inspect the duct routing during rough plumbing or framing inspection. If you can't terminate the duct to a roof or exterior wall without major structural work, say so upfront in your plans; inspectors appreciate honesty and will work with you on alternatives (e.g., a condensing ductless ERV, which requires a separate electrical plan).

Carrollton's permit application process typically starts with an online portal or in-person intake at City Hall. You'll submit a completed application form, proof of property ownership or authorization, a floor plan showing the bathroom layout (existing and proposed, with dimensions), an electrical plan if circuits are being added, a plumbing isometric if fixtures are relocating, and detail drawings for the shower waterproofing assembly if you're doing a tub-to-shower conversion. The application fee is typically $50–$75 (administrative); the permit valuation is estimated based on the cost of materials and labor (you'll declare this on the form), and the permit fee is usually 1.5–2% of the valuation, capped at $300–$700 for a typical full bathroom remodel (expect to estimate $10,000–$20,000 in project cost, which yields $150–$400 in permit fees). Plan review takes 10–15 business days; if there are comments (missing vent-stack details, GFCI not specified, waterproofing system unclear), the city will issue a Submittal Comment letter and you'll have 10 days to resubmit or request an extension. Once approved, you'll receive your permit card and can schedule inspections.

Inspections for a full bathroom remodel in Carrollton typically occur at three key stages: rough plumbing (before drywall, verifying drain/vent layout and trap-arm slope), rough electrical (verifying GFCI circuits, wire routing, and breaker specifications), and final (after all finishes, verifying that the work matches the approved plan and that no code violations are visible). If you're also moving walls or doing structural framing, you may have a framing inspection before plumbing/electrical. Plan 1–2 weeks between each inspection phase; most inspectors will call or email to schedule, so provide a working phone number on the permit. Inspection fees are often bundled into the permit fee, but verify with Carrollton (some jurisdictions charge $50–$100 per inspection). If you're not the licensed contractor performing the work, the contractor must be present for rough inspections to explain the installation details. Once final inspection passes, you'll receive a Certificate of Compliance, which you should keep with your home records and provide to your real-estate agent if you sell — it proves that the bathroom was permitted and inspected. Total timeline from application to final inspection: 4–8 weeks for a straightforward remodel, assuming no major re-submissions and responsive scheduling.

Three Carrollton bathroom remodel (full) scenarios

Scenario A

New exhaust fan and GFCI outlets, vanity in place — Carrollton bungalow, no plumbing moves

Your 1950s Carrollton cottage has no exhaust fan (bathroom gets moldy), and the outlets near the sink have no GFCI protection. You decide to cut a new duct through the roof, install a 50-CFM exhaust fan with a damper and timer, and replace the existing outlets with GFCI outlets. The vanity stays in place; you're not relocating the toilet or sink. This DOES require a permit because you're adding a new electrical circuit (the fan motor) and a new duct that must be inspected for proper termination and slope. You'll submit an electrical plan showing the new circuit (likely a 120V, 15-amp dedicated circuit per NEC 210.21), GFCI outlet specifications, and the duct routing (4-inch diameter, insulated to prevent condensation, terminating through the roof with a hood damper). Plan-review turnaround is typically 8–10 days because the scope is straightforward — no plumbing, no structural changes. Inspection happens after the duct is roughed in (before drywall closure) and after the electrical is roughed (before outlet cover plates). The permit fee is likely $150–$250 because the valuation is modest (exhaust fan kit ~$300, outlet upgrade ~$100, roof penetration and trim ~$400). Total project cost is roughly $1,200–$2,000 if you hire a licensed HVAC tech and electrician; timeline is 3–4 weeks from permit issuance to final inspection. If you skip the permit and the exhaust fan duct terminates into the attic (a common DIY mistake), Carrollton inspectors will catch it during a complaint inspection or if a realtor notices during a home inspection, and you'll face a stop-work order plus a $500–$1,500 fine before you can fix it.

Scenario B

Tub-to-shower conversion, new location, full waterproofing — mid-town Carrollton, frost-depth considerations

You're gutting a main-floor bathroom in a 1970s ranch on Carrollton's east side and converting an old alcove tub to a spacious 5x8 walk-in shower with a bench. The new shower is in a different wall location (requiring a new 2-inch drain line and new hot/cold supply lines routed through the floor — note: Carrollton's frost depth is 12 inches, so pipes under the slab must be below that depth, which is not typically a concern for interior work, but if the slab is shallow or if you're routing pipes near a rim joist, the inspector may flag it). This is a full permit job because you're relocating the drain (trap-arm length and slope must be verified), adding a new venting connection, and installing a waterproofing assembly that differs from the old tub installation. You'll submit a floor plan with new plumbing layout (showing the trap-arm length and vent connection), an isometric plumbing diagram, an electrical plan for any new lighting or heated floor mat, and a detail drawing of the shower waterproofing assembly (e.g., 'Schluter-Kerdi board + RedGard membrane + TileRedi pan' or equivalent — don't just say 'waterproof tiles'). The plan-review timeline is 12–15 days because the plumbing venting and waterproofing details require careful scrutiny. Inspections include rough plumbing (trap arm slope, vent connection, supply-line routing) and framing (to verify the shower enclosure framing meets IRC R602 for wood studs in wet locations). Once drywall is up, you'll have a pre-tile inspection where the waterproofing membrane is inspected for continuity and tears before tile is installed. Permit fee is $300–$500 because the valuation is higher ($8,000–$15,000 for labor and materials). Total project timeline: 5–8 weeks. If you install the shower without a permit and skip the waterproofing membrane (a cost-cutting temptation), you risk mold behind the tile within 2–3 years; worse, when you sell the home, Georgia's Property Disclosure Statement will flag unpermitted work, and the buyer can demand remediation or walk away. Carrollton's inspectors are particularly attentive to shower waterproofing because moisture problems are common in warm-humid climates like Georgia's 3A zone.

Scenario C

Owner-builder, tile and vanity swap in place, no moves — exempt path

You're a Carrollton homeowner and want to refresh your upstairs bathroom by removing old 1980s wall tile and replacing it with new subway tile, removing the old vanity and installing a new one in the same spot (same plumbing connections, no relocating sink), and replacing the toilet with a new low-flow model in the same location. Georgia law (§ 43-41) allows owner-builders to perform work on their own residence without a licensed contractor license, and Carrollton respects this if the work is non-hazardous and doesn't trigger the permit thresholds. Your project is entirely exempt because you're not relocating any fixtures, adding new circuits, installing a new exhaust fan, or moving walls. You do not need a permit for this work. You can pull the vanity, tile, and toilet yourself (or hire a handyperson), run to your local tile supplier and big-box store, and install the new finishes without any city involvement. However, note: if the existing plumbing was unpermitted (e.g., the sink drain line was never inspected), you should still disclose that on a future Property Disclosure Statement — the absence of a permit for YOUR refresh doesn't cure an earlier unpermitted installation. Also, if your home was built before 1978, lead-paint rules (EPA RRP Rule 40 CFR 745) apply to any renovation that disturbs painted surfaces — you'll need to use lead-safe practices (enclosure, HEPA containment, disposal) or hire a certified lead-safe renovator, even though no city permit is required. Plan 1–2 weeks for vanity and tile work if you're handy; total DIY cost is $2,000–$4,000 (tile, vanity, new fittings, grout, sealant). If you hire a handyperson or tile installer, they'll quote $3,000–$6,000 for labor plus materials. No permits, no inspections, no fees — this is the simplest path.

No permit required | Surface-only work (tile and fixture swap in place) | Owner-builder allowed under Georgia § 43-41 | Pre-1978 homes: Lead-safe practices required (federal EPA RRP Rule) | Total DIY $2,000–$4,000 or hired labor $3,000–$6,000 | Timeline 1–2 weeks

Carrollton's exhaust fan and moisture-control code — why Georgia's humid climate tightens the rules

Carrollton sits in Georgia's 3A warm-humid climate zone, meaning your bathroom is exposed to high outdoor humidity (60–90%) year-round. The International Residential Code (IRC M1505) requires exhaust fans in all bathrooms (even guest powder rooms) with a minimum capacity of 50 CFM for bathrooms up to 150 square feet, plus 20 CFM for each additional 150 square feet. In Georgia's climate, undersizing the exhaust fan or improper duct termination (e.g., ducting into the attic instead of to the outdoors) causes mold and moisture damage within months. Carrollton's Building Department is strict about this because too many older homes in the area have attic mold from prior DIY exhaust fan installations that lacked outdoor termination.

When you submit your permit, the city requires the exhaust fan duct to terminate to the outdoors (roof, gable wall, or soffit penetration) via a 4-inch minimum diameter flexible or rigid duct with an insulated jacket to prevent condensation. The duct must slope slightly downward toward the termination point (per IRC M1602.4), and it must have a damper that closes when the fan is off (to prevent backflow and outdoor air infiltration). Many homeowners ask 'Can I use a condensing ERV instead of a traditional duct?' The answer is yes, but it requires a separate electrical circuit and a different plan review. A simple traditional exhaust fan with outdoor duct is faster to approve.

Rough plumbing and rough electrical inspections will include a visual check of the duct routing — if the inspector sees ductwork disappearing into the attic cavity without terminating to the outdoors, that's a fail, and you'll be ordered to reroute it. The cost of rerouting after drywall is up is 3–5x the cost of getting it right the first time, so this is worth $300–$500 in plan consultation upfront to confirm the duct path before you buy materials.

Shower waterproofing assemblies in Carrollton — why 'waterproof tiles' isn't a code-compliant spec

IRC R702.4.2 requires that all wall surfaces of a shower or tub enclosure be lined with a moisture barrier before tile or finishes are applied. This is non-negotiable in Carrollton's plan review — inspectors will ask for a detail drawing or specification sheet showing the waterproofing system, and they will not approve a plan that just says 'waterproof tiles' or 'premium tile.' The code recognizes specific assemblies: cement board (minimum 1/2 inch) with a liquid waterproof membrane (RedGard, Hydroban, Aqua Defense, or equivalent), or a continuous sheet waterproofing system (Schluter-Kerdi, Wedi, or equivalent), or a mortar bed with a tar or bituminous sheet (old-school but code-compliant).

Cement board is the most common and affordable option: 1/2-inch DensShield, Durock, or Hardiebacker behind the tile, sealed with a liquid membrane applied to all joints and penetrations, costs roughly $3–$8 per square foot installed (for a typical 5x8 shower, that's $500–$1,000 in materials and labor). Schluter-Kerdi is more expensive ($10–$15 per sq ft) but faster to install and less mess. Carrollton inspectors prefer to see a recognizable brand with a spec sheet, so when you submit your plan, reference the product by name and include the manufacturer's installation guide in your plan set.

The shower floor pan must also be waterproofed — either a pre-formed pan (like TileRedi) or a traditional mortar bed with a CPE or PVC sheet liner. Many DIYers make the mistake of using a 'waterproof' foam pan kit without a secondary membrane; this is not code-compliant and will eventually leak. Carrollton plan reviews will flag this during the pre-tile inspection (before you grout), so invest in the right pan upfront. For a full bathroom remodel that includes a tub-to-shower conversion, budget $1,500–$3,000 for the shower enclosure waterproofing and floor assembly; it's not glamorous, but it's the difference between a 20-year-old shower and a 2-year-old disaster.

Common questions

Does a full bathroom remodel always require a permit in Carrollton?

No. Only if you're relocating plumbing fixtures, adding new electrical circuits, installing a new exhaust fan, converting a tub to a shower (or vice versa), or moving any walls. If you're just replacing tile, vanity, and fixtures in their existing locations with no electrical or plumbing changes, no permit is required. The calculator on this page will help you identify whether your specific scope crosses the permit threshold.

Can I pull a bathroom remodel permit myself (owner-builder) in Carrollton?

Yes. Georgia state law (§ 43-41) allows owner-builders to pull permits for work on their own residence. Carrollton will accept your application without a licensed contractor license, but you must submit a complete plan package (floor plan, electrical diagram, plumbing isometric, detail drawings for waterproofing) just as a contractor would. Many owner-builders hire a designer or contractor to prepare the plans, then pull the permit and hire subcontractors for individual phases — this is allowed.

What happens if the bathroom plumbing inspection fails in Carrollton?

The inspector will note the specific violations on the inspection report (e.g., 'trap arm slope insufficient,' 'vent connection missing,' 'duct not terminating outdoors'). You'll have 10–15 days to correct the issue, and you'll request a re-inspection. Most issues are fixable (re-slope the drain line, extend the vent, reroute the duct), but if you've already closed up walls or poured concrete, the cost of correction can spike dramatically. This is why rough inspections matter — get the plumbing and duct right before you drywall over it.

Do I need GFCI protection for every outlet in the bathroom, or just ones near the sink?

NEC 210.52(D) requires GFCI protection for all 120V receptacles within 6 feet of the sink, tub, or shower. For a typical bathroom, this usually includes the outlet near the sink and, often, outlets on the opposite wall if the room is small. Carrollton inspectors will measure the distance during rough electrical inspection. A GFCI can be a dedicated breaker at the panel (protecting all outlets on that circuit) or individual GFCI outlets (allowing non-GFCI outlets elsewhere on the circuit). Specify which approach you're taking on your electrical plan.

What's the typical permit fee for a full bathroom remodel in Carrollton?

Carrollton calculates the permit fee as a percentage of the estimated project valuation (typically 1.5–2%). For a full bathroom remodel with plumbing, electrical, and structural changes, estimate $10,000–$20,000 in project cost, which yields $150–$400 in permit fees (plus a $50–$75 application fee). A simple exhaust-fan-and-GFCI upgrade might be $1,200–$2,000, yielding $75–$150 in permit fees. Contact the Building Department for their current fee schedule or ask for an estimate when you submit your application.

How long does plan review take in Carrollton for a bathroom remodel permit?

Standard turnaround is 10–15 business days for a complete, well-prepared application. If the city issues a Submittal Comment letter flagging incomplete details (e.g., missing waterproofing specification, no vent-stack diagram), you'll have 10 days to resubmit. Straightforward projects (exhaust fan only) might be approved in 5–7 days; complex projects (full gut with wall relocation and new plumbing) may take 15–20 days. Submit your application as early as possible to avoid delays during your project timeline.

Do I need a permit to replace a toilet or faucet in the same location?

No. Fixture replacement in place (same supply and drain connections, no relocation) is exempt from permitting in Carrollton. You can DIY or hire a handyperson, no permit needed. If you're also replacing the shutoff valves or supply lines, that's still in-place work and doesn't require a permit — just ensure the new shutoff valves are accessible and functional.

What waterproofing system does Carrollton prefer for shower tile?

Carrollton doesn't mandate a specific brand, but the assembly must be code-compliant per IRC R702.4.2. Most common: 1/2-inch cement board (DensShield or Durock) with a liquid membrane (RedGard or Hydroban) applied to all joints and seams, or a sheet system (Schluter-Kerdi or Wedi). When you submit your plan, specify the product by name and include the manufacturer's spec sheet. The inspector will verify during the pre-tile inspection that the membrane is continuous, fully adhered, and free of tears before you apply tile.

Can I install an exhaust fan duct into the attic in Carrollton?

No. IRC M1505.2 and Carrollton's enforcement require the duct to terminate outdoors (roof, gable wall, or soffit). Ducting into the attic causes condensation and mold, which inspectors will cite on rough inspection. The duct must have an insulated jacket, a damper to prevent backflow, and a hood at the outdoor termination. Budget for the cost of roof penetration and trim if that's not already in your project.

Do pre-1978 homes in Carrollton need lead-safe practices for bathroom remodels?

Yes, if the remodel disturbs painted surfaces (wall demolition, tile removal, etc.). Federal EPA RRP Rule 40 CFR 745 requires lead-safe work practices (HEPA enclosure, containment, certified disposal) or a certified lead-safe renovator on the job. This is separate from the city permit but mandatory for homes built before 1978. Many Carrollton handypeople and contractors are EPA-certified; if yours isn't, you can hire a certified lead consultant to supervise or use certified contractor labor. Budget an extra $500–$1,500 for lead-safe precautions if your home was built before 1978.
