The Short Answer
A full bathroom remodel requires a permit if you're relocating plumbing fixtures, adding electrical circuits, installing a new exhaust fan, converting tub to shower, or moving walls. Surface-only work (tile, vanity swap in place, faucet replacement) does not.
Bartlett, Illinois enforces the 2021 Illinois Energy Conservation Code (which adopts the 2021 International Building Code with state amendments). The City of Bartlett Building Department reviews bathroom remodels under the same IBC framework as its neighboring municipalities, but Bartlett's permit portal and fee schedule are distinct: a full bath remodel (estimated value $8,000–$15,000) typically costs $300–$600 in permit fees, calculated at 1.5-2% of project valuation plus base review fees. Bartlett requires separate rough and final inspections for plumbing and electrical work, which adds 2-5 weeks to plan review. The city also enforces stricter documentation on shower waterproofing assemblies (cement board + membrane systems must be specified by manufacturer) and bathroom GFCI/AFCI protection per NEC 210.12, a common rejection point in plan review. Owner-builders are permitted for owner-occupied single-family homes, but must pull the permit in their own name and be present for all inspections.

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

Bartlett bathroom remodel permits — the key details

Illinois adopted the 2021 IBC (effective January 1, 2023), which Bartlett enforces directly. For bathroom remodels, the pivotal code sections are IRC P2706 (drainage and vent sizing for fixture relocation), IRC M1505 (exhaust fan ventilation — minimum 50 CFM for bathrooms, 80 CFM if moist), IRC E3902 (GFCI protection on all outlet circuits within 6 feet of the sink, tub, or shower), and IRC R702.4.2 (waterproofing assembly for tub and shower enclosures). If you are moving a toilet, sink, or tub, Bartlett requires you to submit a plumbing plan showing trap arm length (maximum 3 feet for 1.5-inch drains, per IRC P3005.2), vent-stack sizing, and new penetrations through the slab or rim joist. If you are adding a new exhaust fan duct (or relocating an existing one), the plan must show termination location (outside the building envelope, not into the attic, per IRC M1505.2). If you are converting a bathtub to a shower, the entire shower enclosure must be waterproofed per the manufacturer's system — this is a frequent rejection point because Bartlett inspectors require a specific waterproofing specification (for example, 'Schluter Kerdi membrane on drywall substrate' or 'cement board with RedGard or equivalent liquid membrane'), not a generic 'waterproofed' note. GFCI and AFCI protection must be shown on the electrical plan; many homeowners assume their existing breaker is sufficient, but NEC 210.12(A) requires either GFCI outlets or a GFCI breaker protecting all bathroom outlets, and NEC 210.12(B) extends this to hallways and other areas where people might escape in case of fire.

Bartlett's Building Department accepts permit applications via its online portal (accessible through the city's website) or in-person at City Hall. The online filing is faster — typically 2-3 weeks to plan review — whereas in-person submission can experience longer backlogs, especially in spring. You will need to submit: (1) a completed permit application, (2) a site plan showing the house footprint and bathroom location, (3) floor plan of the bathroom showing old and new fixture locations (dimensions, distances from walls, and sink-to-toilet clearance of 15 inches minimum per IRC R603.2), (4) plumbing plan (if fixtures are moved), (5) electrical plan showing GFCI/AFCI circuits, (6) exhaust fan specification and duct routing (if new or relocated), and (7) shower/tub waterproofing specification sheet. If you are hiring a licensed plumber and electrician, they often prepare plans as part of their bid; if you are doing work yourself (as an owner-builder), you or a designer must prepare them. Bartlett does not allow owner-builders to pull electrical permits unless they are a licensed electrician, so plan to hire a licensed electrician for any circuit additions or GFCI installations. Plumbing, however, is owner-buildable if you are the homeowner and have the permit in your name.

Bathroom remodels in Bartlett are subject to the Illinois Lead Paint Disclosure Act if the house was built before 1978. Before you disturb any existing paint (which includes removing old tile or vanities), you must provide the homeowner with an EPA-approved lead-paint hazard disclosure, and you must use lead-safe work practices (HEPA vacuums, wet wiping, plastic sheeting) or hire a certified lead abatement contractor. If you fail to disclose, fines are $16,000–$32,500 per violation. This is often overlooked in bathroom remodels because homeowners assume only exterior work triggers it, but interior renovation (including bathroom tile removal) counts. Bartlett inspectors will ask whether the house is pre-1978 and will cite you if you've disturbed paint without proper documentation. Additionally, if you are adding a new bathroom (rather than remodeling an existing one), you must ensure the new bathroom has adequate ventilation, lighting (minimum 50 foot-candles per IBC 803), and exhaust ducting per IRC M1505. A full remodel of an existing bathroom does not change ventilation code minimums if you are keeping the existing duct, but if you are relocating the exhaust duct or replacing it, it must be sized to the current fixture load (typically 50 CFM for a single bathroom, 80 CFM if the bathroom is also the laundry room or primary exhaust for the home).

Inspection sequence for a permitted bathroom remodel typically follows this timeline: (1) Rough Plumbing Inspection (after new drains and supply lines are run but before walls are closed), (2) Rough Electrical Inspection (after new circuits and GFCI outlets are installed but before drywall), (3) Framing/Drywall Inspection (if walls are moved; often combined with plumbing/electrical), and (4) Final Inspection (after all fixtures are installed, tile is complete, and bathroom is functional). Each inspection requires 48-72 hours' notice to the Building Department. If you skip inspections or close walls before rough inspections, Bartlett will order you to open them up, adding weeks and cost. Final inspection is where Bartlett verifies GFCI operation (using a test button), proper vent duct termination (inspectors sometimes do a visual check from outside the building), trap arm length (measured with a tape), and waterproofing spec compliance (inspectors will ask to see the manufacturer's installation documentation). Plan for 4-8 weeks total timeline from permit issuance to final approval, assuming no plan rejections.

Permit fees in Bartlett are based on estimated project valuation. A full bathroom remodel (including fixtures, tile, plumbing, electrical, and labor) typically estimates $8,000–$15,000, which yields permit fees of $300–$600. Bartlett's fee structure is approximately 1.5% of valuation for a standard remodel, with a $100 minimum base fee. If your estimate is high (e.g., $25,000 for a luxury master bath), fees climb to $700–$800. Plan review takes 2-5 weeks; re-submissions (if there are rejections) add another 1-2 weeks per round. Expedited plan review is not typically offered for bathroom permits in Bartlett, so budget for standard timeline. You can request a preliminary meeting with the Building Department (often free or low-cost) to discuss your project scope before submitting the full permit application — this often prevents rejections and is highly recommended if this is your first remodel or if you are uncertain about fixture-relocation code compliance.

Three Bartlett bathroom remodel (full) scenarios

Scenario A
Tile and vanity swap in place — Bartlett ranch, existing plumbing
You are replacing the wall and floor tile, removing the old vanity and toilet (in the same location), and installing new ones. The existing plumbing rough-in (under the slab or within the walls) stays unchanged; you are not moving the sink drain, toilet trap, or supply lines. You are not adding a new exhaust fan — the existing duct remains in place. You are not modifying electrical circuits — the existing outlets stay where they are. This is surface-only work and does NOT require a permit in Bartlett or any Illinois municipality. You can hire a tile contractor and plumber, remove the old fixtures, and install new ones in the same footprint. No permit, no inspections, no fees. However, if the house was built before 1978, you must follow lead-safe work practices when removing old tile and paint. Budget for tiles at $8–$15/sq ft installed, vanity at $300–$800, and labor at $2,000–$4,000. If you are removing the tile and exposing the substrate (drywall or cement board) and notice water damage or mold, stop work and address the root cause (usually a leak from the tub or sink) before reinstalling tile — this is not a permit requirement but a building-science one. Total project cost: $3,000–$6,000 with no permit fees.
No permit required (surface work only) | Lead-safe practices if pre-1978 | Existing plumbing rough-in unchanged | Total cost $3,000–$6,000 | No permit fees
Scenario B
Relocate toilet and sink, new exhaust duct — Bartlett colonial, owner-builder plumbing
You are moving the toilet to the opposite wall and relocating the sink to a corner. Both require new drain lines and supply lines run through the slab (in a basement) or through the rim joist and walls. The existing exhaust fan stays, but you are running a new duct to a different exterior wall (the old duct is capped). You are also not adding electrical circuits — existing outlets are repositioned or remain unused. This requires a PLUMBING PERMIT and a separate EXHAUST FAN PLAN. You, as the homeowner, can pull the plumbing permit and do the work yourself (owner-builder), but you cannot pull an electrical permit for outlet relocation. You must submit: (1) a floor plan showing old fixture locations and new ones, (2) plumbing isometric or plan drawing showing trap arm length for the new toilet (measured from the trap weir to the vent stack, max 3 feet for a 1.5-inch drain per IRC P3005.2), (3) sink drain vent sizing (typically 1.5 inches), and (4) exhaust duct routing and termination location (must exit the building envelope, not the attic). The rough plumbing inspection happens before drywall; inspector measures trap arm length with a tape, checks vent termination and sizing, and verifies supply line pressure (typically 40-80 psi). If trap arm exceeds 3 feet, the plan is rejected and you must relocate the vent stack or add a separate vent — a common and expensive rejection. Permit fee: $350–$500 (based on $10,000–$12,000 estimated project valuation). Timeline: 3-5 weeks plan review, plus 2-3 weeks for rough inspection and any corrections. Total project cost: $6,000–$10,000 including materials and labor, plus $350–$500 permit fees. If you hire a licensed plumber, they typically include the permit in their bid and handle inspections.
Plumbing permit required | Trap arm must be ≤3 ft | Vent stack sizing per IRC P3005 | New exhaust duct termination exterior | Owner-builder plumbing allowed | $350–$500 permit fees | Total $6,000–$10,000
Scenario C
Tub-to-shower conversion, new GFCI circuit, waterproofing system — Bartlett mid-century modern
You are removing a bathtub and installing a shower enclosure in the same footprint (so existing drain and plumbing rough-in stay unchanged), but you are converting the tub valve to a pressure-balanced shower valve and installing a completely new waterproofing system (cement board and liquid membrane per IRC R702.4.2). You are also adding a new GFCI-protected circuit to power an exhaust fan with a humidity sensor (new duct to roof). This requires both a PLUMBING PERMIT (for the valve change and waterproofing specification) and an ELECTRICAL PERMIT (for the new circuit and GFCI breaker). You CANNOT pull the electrical permit yourself as an owner-builder — you must hire a licensed electrician. You can pull the plumbing permit. You must submit: (1) waterproofing specification sheet (e.g., 'Schluter Kerdi membrane system on 1/2-inch drywall substrate, including Kerdi band at corners' or equivalent), (2) shower valve spec showing pressure-balanced feature (required by IRC P2707 for all shower or tub/shower valves to prevent scald), (3) electrical single-line diagram showing the new circuit breaker (GFCI-type or GFCI outlet per NEC 210.12(A)), and (4) exhaust fan schedule with CFM rating and duct termination. The rough plumbing and electrical inspections happen before drywall. Inspector verifies waterproofing substrate is installed correctly (not just specified), measures shower dimensions for code compliance (minimum 30 inches wide by 30 inches deep per IRC P2707.1), and checks valve type. Electrical inspector verifies GFCI protection and duct routing. Plan rejections are common here: if you specify a generic 'waterproofed drywall' without a membrane manufacturer's system, Bartlett will reject it and require you to specify a brand (Schluter, RedGard, Kerdi, etc.). Permit fees: $450–$600 for plumbing (based on $12,000–$15,000 valuation) plus $200–$300 for electrical (new circuit). Timeline: 4-6 weeks plan review (two separate reviews — plumbing and electrical) plus 3 weeks for rough inspections. Total project cost: $8,000–$14,000 including custom shower surround, valve, waterproofing labor, electrical, and exhaust fan. Permits: $650–$900. This is the most code-intensive bathroom scenario and the highest rejection risk if plans are incomplete.
Plumbing permit required | Electrical permit required (licensed electrician) | Waterproofing system must be specified by brand | Pressure-balanced valve required | GFCI circuit or breaker required | New exhaust fan duct to exterior | $650–$900 total permits | 4-6 week plan review | Total $8,000–$14,000

Waterproofing assemblies: the Bartlett rejection point

IRC R702.4.2 mandates that all wet areas of a shower or tub enclosure be waterproofed with a membrane system. Bartlett Building Department interprets this strictly: you cannot simply specify 'waterproof drywall' or 'cement board' and assume compliance. You must provide a specific manufacturer's system — Schluter Kerdi, Wedi, Red Guard, Aqua Defense, or equivalent — with the installation guide attached to the permit. Bartlett inspectors will ask to see the product data sheet and will perform a rough inspection to verify the membrane was installed per manufacturer's instructions (seams lapped, corners taped with mesh, etc.) before drywall and tile go on top.

The most common mistake is specifying just 'cement board with latex waterproofing' — cement board is not inherently waterproof; it is moisture-resistant. If water penetrates the tile grout and gets behind cement board, it will rot the framing. The code-compliant approach is cement board PLUS a liquid membrane (applied between cement board and tile) or a sheet membrane (like Kerdi, applied over drywall). Bartlett's plan-review staff will reject a waterproofing specification that is not specific to a product, forcing a re-submission. Budget an extra 1-2 weeks and a plan re-submission if your first plans do not include a waterproofing product spec.

For new showers or tub enclosures, ensure grout and caulk are also specified correctly. Unsanded grout is required for joints less than 1/8 inch; this detail matters to Bartlett inspectors if they spot check the final tile work. Use epoxy or urethane caulk (not silicone) at the corners and edges where the membrane meets substrate — this is not a code requirement but a best practice that Bartlett's more detail-oriented inspectors will note. The waterproofing specification adds $200–$400 to labor costs but prevents $5,000+ water-damage repairs down the line.

GFCI and AFCI protection — electrical pitfalls in Bartlett bathroom remodels

NEC 210.12(A) requires GFCI protection for all outlets in bathrooms (defined as an area with a toilet, sink, or tub). This includes the vanity outlet, the outlet above the toilet (if present), and any outlet within 6 feet horizontally of the sink, tub, or shower. Many homeowners believe an old home's existing circuit is sufficient — it is not. If you are adding a new outlet or replacing an existing one, it must be GFCI-protected, either by installing a GFCI outlet (which protects itself and outlets downstream on the same circuit) or by installing a GFCI breaker in the electrical panel (which protects the entire circuit). Bartlett's electrical inspector will test the GFCI operation using the test button during rough and final inspections. If the GFCI outlet fails the test, the inspection fails.

A secondary requirement applies to bathrooms in Bartlett homes built after 2008: NEC 210.12(B) requires AFCI protection (Arc Fault Circuit Interrupter) for circuits in bathrooms. AFCI breakers protect against electrical fires from arc faults in the wiring. If you are adding a new circuit to the bathroom, it must be either a combination GFCI/AFCI breaker (if the panel supports it) or separate GFCI and AFCI protection. Older electrical panels may not have combination breaker slots, so upgrade may be necessary — a $500–$1,500 panel upgrade if the panel is full or lacks compatible breaker space.

The permit application's electrical plan must clearly label which outlets have GFCI protection and which breaker (GFCI or GFCI/AFCI combination) controls them. Bartlett inspectors will compare the plan to the actual installation during rough inspection. If the plan shows GFCI outlet at the vanity but the finished installation has a standard outlet, the inspection fails. This detail is often overlooked by owner-builders and leads to inspection rejections and costly rewiring.

Common questions

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

No. Replacing a toilet in the same location (same rough-in, same trap) does not require a permit in Bartlett. You can hire a plumber or do it yourself. If you are moving the toilet to a new location, you do need a plumbing permit because a new drain line and vent are required. If the house was built before 1978, lead-safe practices apply when disturbing any paint, even around the toilet flange.

What is the time frame for a bathroom remodel permit in Bartlett?

Permit issuance: 3–5 business days (if plans are complete and approvable). Plan review: 2–5 weeks (depending on complexity and rejection rounds). Rough inspections: 1–2 weeks after permit issuance (scheduled at your request). Final inspection: 1–2 weeks after rough sign-off. Total timeline: 6–10 weeks from permit submission to final approval, assuming no major rejections. Expedited review is not typically available for bathroom permits in Bartlett.

Can I pull a bathroom remodel permit myself as the homeowner?

Yes, you can pull the permit yourself in Bartlett if you are the owner-occupant. However, you cannot perform or permit electrical work unless you are a licensed electrician — you must hire one for any circuit additions, GFCI installations, or exhaust fan wiring. Plumbing and carpentry work (fixture relocation, wall removal, drywall) can be owner-built. If you hire licensed contractors (plumber, electrician), they often pull and manage the permits as part of their service.

What happens if I remove a wall in my bathroom without a permit?

Removing a load-bearing wall requires a structural permit and engineer design — this is not a bathroom permit but a separate structural permit in Bartlett. If you remove a non-load-bearing wall (partition), it typically requires a remodeling permit because it affects the bathroom layout, plumbing access, and egress. Bartlett inspectors can require you to identify whether the wall is load-bearing via engineer evaluation, which adds $300–$800 to your project cost. Removing a wall without a permit and having it discovered at resale can trigger mandatory disclosure and remediation demands.

Do I need a permit for a tub-to-shower conversion?

Yes. A tub-to-shower conversion requires a plumbing permit because you are changing the fixture type and the waterproofing assembly (per IRC R702.4.2). You must specify the waterproofing system (e.g., cement board + liquid membrane, or Schluter Kerdi) on the permit plan. The valve must also be a pressure-balanced or thermostatic mixing valve (per IRC P2707). The existing drain and supply rough-in can often stay in place if the drain location is compatible with the new shower pan, but the vent and valve must be verified for code compliance.

What is a 'trap arm' and why does it matter for a relocated toilet?

A trap arm is the horizontal section of drainpipe between the toilet trap outlet and the vent stack. IRC P3005.2 limits trap arm length to 3 feet for a 1.5-inch toilet drain. If your new toilet location is more than 3 feet away from the nearest vent stack, you must either (1) relocate the vent stack, (2) add a separate vent for the toilet, or (3) use a low-loop or island vent system. Exceeding 3 feet results in siphoning of the trap seal and foul odors. Bartlett inspectors measure trap arm length during rough inspection; if it exceeds the limit, the inspection fails and you must remedy it — a costly and time-consuming correction.

Is a GFCI outlet the same as a GFCI breaker?

They serve the same protective function but differ in scope. A GFCI outlet protects itself and any downstream outlets on the same circuit (if it is installed first in the line). A GFCI breaker (in the electrical panel) protects the entire circuit. For bathrooms, either is acceptable per NEC 210.12(A). A GFCI outlet costs $15–$25, while a GFCI breaker costs $40–$60. If you have multiple outlets in the bathroom, a GFCI breaker is more cost-effective and cleaner. Bartlett inspectors will verify GFCI operation using the test button during inspection.

What do I need to submit with a bathroom remodel permit application in Bartlett?

Typical requirements: (1) completed permit application, (2) site plan (house footprint and bathroom location), (3) floor plan showing old and new fixture locations with dimensions, (4) plumbing isometric or plan (if fixtures are moved), (5) electrical single-line diagram showing GFCI/AFCI circuits (if new circuits are added), (6) exhaust fan specification and duct routing (if relocated or new), and (7) waterproofing specification sheet (if shower/tub is converted or rebuilt). Plans can be hand-drawn (legible) or computer-generated. If you work with a contractor or designer, they usually prepare these. Bartlett's online permit portal has a checklist; review it before submitting to avoid delays.

Will unpermitted bathroom work affect my home sale?

Yes, significantly. Illinois Residential Real Property Disclosure Act requires disclosure of any unpermitted improvements. If a bathroom remodel was completed without a permit, you must disclose it on the TDS (Transfer Disclosure Statement). Buyers and their inspectors will likely demand that unpermitted work be brought to code (via retroactive permit, inspection, and remediation), which can cost $2,000–$10,000 and delay closing. Some buyers will not proceed with the purchase unless work is legalized. Lenders may also refuse to refinance a home with undisclosed unpermitted work. A $400 permit up-front is far cheaper than these consequences.

What is the cost of a bathroom remodel permit in Bartlett?

Bartlett's permit fee is based on estimated project valuation. A typical full bathroom remodel (fixtures, tile, plumbing, electrical, labor) estimates $8,000–$15,000, yielding permit fees of $300–$600 (approximately 1.5–2% of valuation plus a base fee). A high-end remodel ($20,000+) can incur $700–$900 in permits. Ask the Building Department for a fee estimate before submitting; they will calculate it based on your stated project scope. Plan review (included in the permit fee) typically takes 2–5 weeks. Expedited review is not usually available.
