The Short Answer
A full bathroom remodel in Melrose Park requires a permit if you're relocating plumbing fixtures, adding new electrical circuits, installing a new exhaust fan duct, converting a tub to shower, or moving walls. Surface-only work—replacing a toilet, vanity, or faucet in place—does not require a permit.
Melrose Park, a Cook County municipality adjacent to Chicago, enforces the 2015 International Building Code with local amendments and operates a hybrid permit-review process: small projects (≤$10,000 valuation) often qualify for over-the-counter approval same-day if electrical and plumbing drawings are complete and GFCI/exhaust-duct termination details are shown; larger remodels go through full plan review, typically 2–3 weeks. The city's building department requires a separate electrical permit from the City of Melrose Park (not the village of Proviso, which covers some adjacent areas—confirm your address on the city website). Melrose Park is in Cook County's 42-inch frost zone, which affects new drain-stub depth and sump-pump requirements if you're digging. The city applies lead-paint rules (RRP disclosure, EPA cert) to any pre-1978 home, which increases project cost by $200–$400 for testing and containment. Unlike some North Shore suburbs that allow unlimited owner-builder work, Melrose Park limits owner-builder permits to single-family owner-occupied homes only—if the home is investment property or a multi-unit, you must use a licensed contractor.

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

Melrose Park full bathroom remodel permits — the key details

The primary rule: IRC P2706 (drain and vent fitting requirements) and IRC M1505 (bathroom exhaust ventilation) require a permit anytime you relocate a drain line, add a new vent stack, or install a new exhaust fan duct. Melrose Park's building code also requires that any new or relocated toilet have a trap arm no longer than 3 feet 6 inches (IRC P3005.2) and minimum 1.5-inch drain line slope of 1/4 inch per foot—violations show up immediately in rough plumbing inspection and force rework. The exhaust fan must terminate at least 10 feet from any operable window or door (IRC M1505.2); if you're ducting to the attic (a common error), the city will reject that at framing inspection. GFCI protection for all bathroom receptacles within 6 feet of the tub/shower is mandatory (NEC 210.8), and Melrose Park's electrical inspector verifies this on the rough-electrical inspection—if your electrician didn't pull a permit and didn't label the GFCI circuit on the panel, the final inspection fails and the home can't be used legally. A full bathroom remodel that includes a tub-to-shower conversion or new shower enclosure triggers IRC R702.4.2 (shower/tub waterproofing): you must specify the waterproofing assembly on your permit drawings—cement board plus liquid membrane, schluter pan system, or equivalent—because building-science failure here leads to framing rot within 3–5 years, and the city's final inspector will demand photographic proof of installation before sign-off.

Melrose Park has a unique local rule: if the remodel touches the main toilet drain line or includes a new secondary drain (e.g., a bidet or new shower), you must have Cook County's public-works department confirm that your sump-pump discharge (if present) does not conflict with the city's sanitary or storm sewer lateral. This is not a formal permit but a courtesy call; it costs nothing but can add 1–2 weeks if the city's GIS system flags your address as a potential sump-discharge issue. For homes built before 1978, Melrose Park requires an RRP (Renovation, Repair, and Painting) disclosure per EPA rules; if the permit includes drywall removal or floor scraping, you must hire an EPA-certified lead-paint contractor ($200–$400 for testing and containment alone). The city's building permit portal (melroseparkillinois.org or check the city hall front desk) allows online application submission for electrical and plumbing permits, but the department prefers a completed B1 form (Illinois-standard general construction permit) printed and hand-delivered to City Hall with one set of plans and a check—online submission often takes 3–5 days longer for review initiation because staff prioritizes walk-in submittals.

Exemptions are narrow but real. Replacing a toilet, vanity, faucet, or shower head in the same location and with the same rough-in dimensions does not require a permit. Removing a wall-mounted towel rack or soap dispenser doesn't require a permit. Retiling an existing tub surround or shower enclosure (without changing the underlying waterproofing assembly or moving fixtures) is permit-exempt in Melrose Park as long as you're not opening the wall framing—if you discover mold or water damage during demo and must replace sheathing or studs, you then need a permit for that structural repair. However, if you're removing a tub and installing a new one in the same rough-in, the city's electrical inspector will ask to see the old GFCI setup: if the existing receptacle is not GFCI-protected, the new installation must add it, which triggers an electrical permit. Owner-builders in Melrose Park are allowed for single-family owner-occupied homes but must pull a separate owner-builder affidavit (available from City Hall) and are liable for all inspection defects; contractors (even unlicensed ones) cannot file owner-builder permits.

The permit-valuation formula in Melrose Park is roughly 1.5–2% of estimated project cost, capped at $800 for remodels under $50,000. A typical full bathroom remodel (new fixtures, tile, plumbing relocation, exhaust fan, GFCI) costs $8,000–$15,000 and triggers a permit fee of $250–$400. If you're adding a secondary bathroom (rather than remodeling an existing one), the fee is higher because the city classifies it as new occupancy, not alteration. Plan-review time is 2–3 weeks for a simple fixture-relocation remodel with complete drawings; if the city's electrical or plumbing inspector has questions about GFCI layout, trap-arm configuration, or exhaust-duct termination, review extends to 4–5 weeks. Inspection sequence is typically: rough plumbing (before drywall), rough electrical (before drywall), framing (if walls are moved), drywall or tile prep (optional inspection), and final (after all work is complete). If you're working with a general contractor, they often handle permit filing; if you're owner-builder, you can file online or at City Hall, and the department will assign one inspector for all trades (making follow-up faster).

Cook County's 42-inch frost depth (Melrose Park is in the deeper-frost zone north of the Chicago River) means any new drain stub in a basement or crawlspace must slope below frost line if it exits to a yard catch basin—a common miss that triggers a frost-depth inspection failure. If your remodel includes a new or relocated toilet in a basement bathroom, the city will verify that the trap and slope meet the 42-inch frost requirement; if you're connecting to an existing line that's already legal, no additional work is needed. Lead-paint rules are strict: any pre-1978 home that has drywall cutting or demolition as part of the remodel must have an EPA-RRP cert on the job; if an inspector finds RRP violations (no plastic sheeting, no HEPA vacuum), the job is shut down and you face a $5,000–$10,000 EPA fine. Finally, Melrose Park's final inspection is pass-or-fail; there is no 'substantial completion' approval for missing trim or touch-ups—the city will not sign off the permit until all work (including caulking, grout, paint, and fixture installation) is visually complete, so budget an extra 3–5 days at the end for punch-list cleanup.

Three Melrose Park bathroom remodel (full) scenarios

Scenario A
Vanity swap and retiling in a 1990s ranch, same drain location, new GFCI, existing exhaust fan stays
You're replacing a 24-inch vanity with a new 36-inch one in the same rough-in, retiling the surrounding wall (opening up drywall), and installing a new GFCI-protected receptacle above the vanity. Because the new vanity has the same p-trap location and you're not relocating the drain line, many homeowners assume no permit is needed—but Melrose Park requires a permit if the electrical outlet is being replaced or upgraded (even in-place). If the old outlet was not GFCI-protected, the new one must be, and that requires an electrical permit. The plumbing inspector will sign off on the vanity swap at rough plumbing inspection (about 3 days after you submit); the electrical inspector needs to verify GFCI on the new circuit before drywall goes up. The permit fee is $200–$300 for a combined plumbing and electrical permit (not separate fees in Melrose Park for small remodels under $5,000). Timeline is 2–3 weeks from submission to final inspection. The retiling work itself (opening drywall, installing cement board, tiling) is permit-exempt, but if you discover water damage or mold during demo, that repair (sheathing or framing replacement) must be added to the permit as a structural alteration. The home is 1990s (post-1978), so no lead-paint RRP is required. Total project cost $3,000–$5,000 including tile, vanity, plumbing rough-in labor, and electrical; permit fees $200–$300; timeline start-to-finish is 3–4 weeks.
Electrical permit required (GFCI upgrade) | Plumbing permit required (vanity relocation considered fixture move) | No lead paint testing (post-1978) | $200–$300 permit fees | $3,000–$5,000 total project cost | Rough plumbing + electrical inspections | Final inspection after all finishes complete
Scenario B
Full gut remodel with tub-to-shower conversion, new 2x6 wall framing, relocated second drain for bidet, pre-1978 colonial in Melrose Park
You're gutting the bathroom down to framing, moving one wall to expand the shower, converting a tub to a walk-in shower with a new drain line (for a bidet toilet), and installing a new exhaust fan duct to the exterior. This triggers multiple permit requirements: plumbing (new shower drain, bidet line, exhaust vent), electrical (new GFCI circuits, exhaust fan switch), framing (wall relocation), and structural. The tub-to-shower conversion is a code flashpoint: you must specify the shower waterproofing assembly on the permit drawings (e.g., Schluter-KERDI or cement board + RedGard liquid membrane); the city's inspector will do a pre-drywall waterproofing inspection to verify the membrane or pan system is installed correctly before drywall is hung. The home is pre-1978 (colonial era, likely 1950s–1960s), so you must hire an EPA-certified RRP contractor for all drywall demolition, paint scraping, and dust control; Melrose Park requires proof of RRP certification on the permit (a copy of the cert must be submitted with the permit application). The new wall framing is subject to framing inspection (the inspector checks for proper header size, blocking, and plumb); the new drain line for the bidet must have a trap arm no longer than 3 feet 6 inches and slope of 1/4 inch per foot—if the line runs more than 8 feet horizontally, you may need a secondary vent, which the plumbing inspector will flag. The exhaust fan must discharge to the exterior (not the attic), at least 10 feet from any window—the rough framing inspection includes a duct-termination verification. The permit fee is $500–$800 because the valuation is $15,000–$20,000; plan-review time is 3–4 weeks because the city's plan reviewer will scrutinize the waterproofing detail, GFCI layout, and framing design. Lead-paint abatement (RRP cert, containment, HEPA vacuum) adds $400–$600 to the project. Inspection sequence: rough plumbing (before drywall), rough electrical (before drywall), framing (if not already framed), waterproofing/shower-pan pre-drywall, drywall, rough final (tile/fixture readiness), final (all finishes). Total timeline: 5–7 weeks from permit submission to final sign-off. Total project cost: $18,000–$25,000 including labor, fixtures, tile, and waterproofing; permit fees $500–$800; RRP services $400–$600.
Permit required (multiple trades: plumbing, electrical, framing, structural) | Tub-to-shower waterproofing assembly must be specified on plans | Bidet drain requires trap-arm verification and secondary vent | Exhaust duct must terminate to exterior, 10+ feet from windows | RRP contractor required (pre-1978 home) | GFCI on all bathroom circuits | Lead-paint disclosure and testing | $500–$800 permit fees | $18,000–$25,000 total project cost | 5-7 week timeline
Scenario C
Second-story powder room addition (new bathroom) in owner-occupied, new plumbing stack, electrical roughed by licensed electrician, no wall changes
You're adding a new half-bath (toilet and pedestal sink) on the second floor of an owner-occupied home; this is NOT a remodel of an existing bathroom but a new bathroom addition. Melrose Park treats new bathrooms as additions with different code triggers: you need a plumbing permit (new toilet and sink rough-in, new vent stack through the roof), an electrical permit (new circuit for lights and receptacle), a framing inspection (if you're opening ceiling framing to run the vent stack), and a structural review if the new plumbing stack requires lateral bracing. The vent stack must be 4-inch minimum diameter (IRC P3101.1) and must extend at least 12 inches above the roof line; the city's roof inspector will verify vent termination. The new toilet's trap arm is subject to the same 3 feet 6 inch maximum rule (IRC P3005.2), and the p-trap must be within 6 feet of the stack (IRC P3004). If you're owner-builder, you can pull the permit yourself (file an owner-builder affidavit), but if you hire a licensed electrician, they will pull the electrical permit separately; Melrose Park requires electrical permits to be filed by the electrician or the homeowner (not the GC). The plumbing portion is usually filed by a licensed plumber. Permit fees are typically $300–$500 for the plumbing permit and $150–$250 for the electrical permit (combined $450–$750); plan-review time is 2–3 weeks. Inspection sequence: framing (if opening ceiling), rough plumbing (toilet/sink rough-in and vent stack), rough electrical (circuit and outlet placement), and final (after fixtures installed). The home is owner-occupied, so you qualify for owner-builder filing; if the home is investment property, you must use licensed contractors (both plumbing and electrical). Timeline is 4–5 weeks from permit submission to final. Total project cost (fixtures, plumbing rough-in, electrical, tile, drywall patch): $4,000–$6,000; permit fees $450–$750; no lead-paint issue (assuming post-1978 construction or no demolition).
Permit required (new bathroom addition, not remodel) | Plumbing permit required (new vent stack, trap arm, p-trap) | Electrical permit required (new circuit and fixture) | Vent stack must be 4-inch, extend 12+ inches above roof | Owner-builder eligible (single-family owner-occupied) | Separate permits: electrical (electrician files) and plumbing (plumber or homeowner) | $450–$750 total permit fees | $4,000–$6,000 project cost | 4-5 week timeline

GFCI and AFCI protection in Melrose Park bathrooms: what the code requires and what inspectors check

NEC 210.8(A) requires GFCI protection for all 15- and 20-ampere receptacles within 6 feet of the edge of a tub or shower (measured horizontally). Melrose Park's electrical inspector interprets '6 feet' strictly: if your vanity is 7 feet from the tub edge, a standard receptacle is legal there, but any outlet within 6 feet—including the vanity outlet, a wall sconce, and exhaust-fan switch outlet—must be either GFCI-protected at the outlet itself or on a GFCI circuit breaker. Many older bathroom circuits were not GFCI-protected, so during a remodel, the new outlet must be upgraded. The inspector will examine the electrical rough-in plan and mark any receptacles that appear to be in the GFCI zone on the as-built.

Melrose Park's building code also requires AFCI (Arc Fault Circuit Interrupter) protection on all branch circuits serving bathrooms per NEC 210.12(B)—not just outlets within 6 feet of the tub, but the entire bathroom circuit. If you're adding a new bathroom or remodeling and pulling a new electrical permit, the city's inspector will require either an AFCI breaker or individual AFCI outlets for all bathroom circuits. This is a frequent rejection point: contractors often forget to specify an AFCI breaker on the permit plan, and the city's plan reviewer will write a deficiency (RFI—Request for Information) asking for clarification. Your electrician must respond in writing confirming AFCI protection; if they submit a plan showing standard breakers, the permit is delayed 1–2 weeks while the city re-reviews.

A practical tip: on your permit application, explicitly note 'All bathroom receptacles protected by GFCI (outlet or breaker); all bathroom circuits protected by AFCI breaker per NEC 210.8 and 210.12' in the electrical narrative section. This preempts plan-review delays. During rough electrical inspection, the inspector will test the GFCI outlets with a GFCI tester and will visually verify that AFCI breakers are installed in the main panel. If a breaker is missing or mislabeled, the rough fails and you must correct it before drywall is hung.

Shower waterproofing assemblies and Melrose Park's pre-drywall inspection protocol

IRC R702.4.2 specifies that shower and tub surrounds must be waterproofed with a continuous water-resistive membrane under tile or other wall finish. The two most common systems are cement board + liquid membrane (e.g., RedGard, Aqua Defense) and pre-fabricated waterproof pans (Schluter, Wedi, Hydro Ban). Melrose Park's building inspector will demand visual proof of the waterproofing assembly before drywall is hung over it—this is called the pre-drywall or waterproofing inspection. You must schedule this inspection after framing and membrane installation but before drywall mudding or tile is applied.

The city's pre-drywall inspection checklist includes: (1) membrane is continuous from the pan up the walls at least 6 inches above the rim of the tub/shower (IRC P2703); (2) all seams and penetrations (drain, valve, etc.) are sealed with appropriate joint compound or foam; (3) the pan (if used) is properly sloped to the drain (minimum 1/4 inch per foot); (4) there are no gaps, tears, or incomplete coverage. If the inspector finds waterproofing defects—e.g., the membrane is only 3 inches high instead of 6, or a seam is not sealed—they will write a deficiency and require you to correct it before proceeding. This is not a fail-the-project-stop, but it delays drywall by 3–5 days. The inspection fee is included in the permit fee (no separate charge).

A common error is using drywall (even moisture-resistant drywall like green board) instead of cement board in the shower enclosure. Melrose Park's inspector will reject this: the code explicitly requires cement board or equivalent water-resistant sheathing under the membrane. If you've already installed drywall and the inspector discovers it, you must tear out the drywall and install cement board—a costly rework. Budget $60–$80 per sheet for cement board plus labor ($200–$400 total for a typical 5x8 shower surround); if you discover this mistake during framing, it's cheap; if after drywall is mudded and taped, it's expensive.

Common questions

Do I need a permit if I'm just replacing my toilet or vanity in place?

No permit is required for a toilet or vanity swap if the rough-in dimensions (drain location, water supply line) remain the same and the existing outlet is already GFCI-protected. If the old outlet is not GFCI-protected, you must upgrade it, which triggers an electrical permit. Check with Melrose Park's building department or your electrician before assuming it's permit-exempt; when in doubt, call City Hall at (708) 343-4000.

What's the cost and timeline for a full bathroom remodel permit in Melrose Park?

Permit fees typically range from $250–$800, depending on project valuation (1.5–2% of estimated cost). Plan-review time is 2–4 weeks; if the city requests clarification on GFCI layout, exhaust-duct termination, or waterproofing details, review extends to 5 weeks. Inspection sequence (rough plumbing, rough electrical, waterproofing, final) takes another 2–3 weeks, so total timeline is 4–8 weeks from submission to final sign-off.

Do I need a separate electrical permit for a bathroom remodel, or is it included in the plumbing permit?

Electrical and plumbing permits are separate in Melrose Park. The electrician or homeowner must file the electrical permit; the plumber or homeowner files the plumbing permit. On small remodels under $5,000, the city sometimes issues a single 'combination' permit for both, but each trade is inspected separately. If you're using a GC, they can coordinate both permits; if you're owner-builder, you file both yourself (or have each contractor file theirs).

My bathroom is in a pre-1978 home. Do I need special permits or testing?

Yes. Any remodel involving drywall removal, paint scraping, or demolition in a pre-1978 home must comply with EPA's RRP (Renovation, Repair, and Painting) rule. You must hire an EPA-certified RRP contractor; Melrose Park requires proof of RRP certification submitted with the permit. Lead-paint testing and containment costs $200–$600; if lead is found, the contractor must use HEPA vacuums and plastic containment. Failure to follow RRP rules results in EPA fines up to $10,000.

Can I do the work myself (owner-builder) for a bathroom remodel in Melrose Park?

Yes, owner-builder permits are allowed for single-family owner-occupied homes. You must file an owner-builder affidavit available from City Hall and are personally liable for all code compliance and inspections. If the home is rental property or a multi-unit building, you must use a licensed contractor. Owner-builder permits have the same fee and timeline as contractor permits.

My contractor wants to duct the exhaust fan to the attic instead of through the roof. Is that legal in Melrose Park?

No. IRC M1505.2 requires exhaust fans to terminate to the exterior (roof or wall), not the attic. Melrose Park's building inspector will flag this at the framing or rough-plumbing inspection and require ducting to the outside. If the ducting already goes to the attic and is covered by drywall, you must cut it out and re-route to the exterior—a costly repair. Plan for roof termination from the start.

What happens if I convert a tub to a shower? Does that require a special permit?

Yes. Tub-to-shower conversion is a plumbing and waterproofing change that requires a permit. You must specify the shower waterproofing assembly (cement board + liquid membrane, Schluter pan, or equivalent) on the permit plans, and the city will do a pre-drywall waterproofing inspection to verify the membrane is properly sealed and covers at least 6 inches above the shower rim. If waterproofing is defective, the inspection fails and you must correct it before drywall is installed.

My new shower drain is 10 feet from the main stack. Is that allowed?

Drain trap-arm length is limited to 3 feet 6 inches from the trap to the vent stack per IRC P3005.2. If your drain is more than 6 feet away horizontally, you likely need a secondary vent line (a 1.5-inch line running up and through the roof or tying into an existing vent stack above the highest fixture). The city's plumbing inspector will review your rough-in plan and flag if a secondary vent is required. This adds $300–$500 to plumbing costs and may require an additional roof penetration.

How much does a full bathroom remodel cost in Melrose Park including permit fees?

A full bathroom remodel (new fixtures, tile, plumbing relocation, exhaust fan, GFCI electrical) typically costs $10,000–$18,000 in materials and labor, plus $300–$800 in permit fees. If the home is pre-1978, add $200–$600 for lead-paint RRP services. If you're converting a tub to shower or adding a secondary vent, add $500–$1,000. If you're owner-builder and doing some work yourself, you can reduce labor costs by 30–50%, but the permit fee and inspector timeline remain the same.

Do I need to notify the City of Melrose Park about the permit before I start work, or can I start and apply for a permit later?

You must apply for and receive the permit BEFORE starting any work. Starting work without a permit is illegal and subject to stop-work orders and fines ($150–$300 per day). If you've already started unpermitted work and want to legalize it, the city may require a retroactive inspection and fee ($400–$800) and can impose penalties. Always pull the permit first, even if it delays your start date by a week or two.
