Glendale Heights full kitchen remodel permits — the key details

Glendale Heights requires a building permit for any kitchen remodel that involves wall movement, load-bearing wall removal, plumbing fixture relocation, new electrical circuits, gas line modification, or exterior range-hood venting. This is not a gray area: the 2021 Illinois Building Code Section R101.1 mandates permits for alterations that affect structure, plumbing, electrical, gas, or HVAC systems. The only true exemptions are cosmetic-only work — cabinet and countertop replacement in the same location, flooring, paint, and appliance swap on existing receptacles (e.g., replacing a gas range with an electric range on an existing circuit). Everything else needs a permit. Glendale Heights has NO owner-builder threshold that carves out 'small' kitchen work; if you're touching one of the regulated systems (plumbing, electrical, structural), you need a permit, period. The city does allow owner-builders to pull permits for owner-occupied homes, which can save money on contractor licensing fees, but the owner must be present for final sign-off on all inspections.

Three separate permits are almost always required: building (structural, ventilation, general), plumbing (sink, dishwasher, drain relocation, venting), and electrical (circuits, receptacles, GFCI). The plumbing permit is often the bottleneck because Glendale Heights enforces ICC Chapter 25 (P2722 — kitchen drains must have proper trap arm and venting). If you're relocating the sink more than 5 feet from its current location, the vent stack routing changes, which requires a plumbing drawing showing the trap arm slope (1/4 inch per foot), vent size, and connection to the main vent stack. A mechanical (HVAC) permit is triggered if you're adding or modifying a range hood with exterior ducting — the duct cannot simply exit the wall; it must terminate with a damper and cap, and the duct routing must be shown on the mechanical plan. Lead-based paint is another gotcha: if your home was built before 1978, you must attach a Lead-Based Paint Disclosure Affidavit (available from the EPA or Glendale Heights Building Department) to your building permit application. The city will reject your permit application if this form is missing. Failure to disclose is a federal violation and can carry fines of $16,000+.

Plan submission in Glendale Heights is 100% digital through the city's permit portal — there is no in-person or mail option. Your building plan must include site plan (showing property lines and house footprint), floor plan (showing wall locations and fixture positions), electrical plan (showing all new circuits, switch locations, GFCI receptacles, and the required two 20-amp small-appliance branch circuits per IRC E3702.1), plumbing plan (showing drain routing, trap arms, and vent connections), and if applicable, mechanical plan (range-hood duct routing and termination detail). The electrical plan is often rejected on first submission because homeowners or contractors forget to show the two dedicated 20-amp circuits for countertop receptacles — one on each side of the sink. If you're moving the refrigerator, that's a separate 20-amp circuit (IRC E3702.3). Every receptacle within 6 feet of the sink must be GFCI-protected, and the plan must detail this. If you're adding a gas cooktop or replacing gas plumbing, you need a gas line drawing showing the new run, shutoff valve, and connection to the meter — this requires a licensed gas fitter in Illinois (not an owner-builder exception), so coordinate with a plumber or gas contractor before filing. Plan review in Glendale Heights typically takes 2-4 weeks; if there are rejections (which are common), add another 1-2 weeks per resubmission.

Inspection sequencing is rigid: rough plumbing first (vent and trap routing visible), rough electrical second (circuits roughed in, but not covered), framing/structural third (if walls are moved or load-bearing walls modified), insulation/drywall fourth, and final last (all fixtures roughed, finishes on, plumbing and electrical ready for operation). Each trade gets its own inspection appointment; you cannot combine them. If you're removing a load-bearing wall, the city will require an engineering letter or beam-sizing calculation stamped by a structural engineer licensed in Illinois. This is non-negotiable and adds 1-2 weeks to the plan-review timeline. Inspections in Glendale Heights are booked online or by phone (verify current scheduling method with the Building Department) and typically have a 3-5 day window; if you miss an inspection, you forfeit the appointment and must rebook, which delays the project. Final inspection is the closest to a walk-through — the inspector verifies that all rough work matches the approved plan, all fixtures are operational, and all code citations are addressed. Do not finish drywall, paint, or install cabinets until final is signed off; the inspector needs to see the rough work.

Permit fees in Glendale Heights are calculated as a percentage of the project valuation, typically 1.5-2% for a kitchen remodel. A $30,000 remodel pays $450–$600 in building permit fees; add $200–$400 for plumbing and $150–$350 for electrical. If you're removing a load-bearing wall, expect an additional structural-engineering review fee of $200–$500. Total permit cost is usually $800–$1,500 for a full kitchen remodel. These fees are non-refundable, even if you cancel the project mid-stream. Payment is due when you file the application, and the city accepts credit card, check, or electronic transfer through the portal. Plan to allow 4-6 weeks from the day you file to the day you get final sign-off, assuming no rejections and no inspector no-shows. Rushing the process (same-day or next-day plan review) is not available in Glendale Heights; the standard review is what you get.

Three Glendale Heights kitchen remodel (full) scenarios

Glendale Heights electrical code quirks: two appliance circuits and GFCI confusion

IRC E3702.1 (adopted by Illinois and enforced by Glendale Heights) requires at least two 20-amp small-appliance branch circuits in a kitchen, and they must serve only kitchen countertop receptacles, the refrigerator, and the dishwasher (no other rooms). The two circuits must be separate and independent — you cannot run both from the same breaker or panel location, and you cannot combine them into a larger 40-amp circuit. This is a constant rejection point in Glendale Heights: contractors or homeowners show one circuit serving the countertop and assume the appliance circuit (for fridge and dishwasher) is the second — but the city's plan reviewer will flag this and ask for confirmation that both are 20-amp, separate circuits.

GFCI protection adds another layer. Every receptacle within 6 feet of the sink must be GFCI-protected (IRC E3801.4). This includes countertop receptacles, island receptacles, and any other kitchen receptacle in the splash zone. The plan must show GFCI outlets at the receptacle locations, not just a notation that GFCI is 'provided via breaker.' Individual GFCI receptacles (with outlets) are preferred in Glendale Heights because they are more testable and visible during inspection. If you use a GFCI breaker in the panel to protect multiple outlets, you must still show the circuit clearly on the plan and note the breaker location.

If you're adding a dishwasher or garbage disposal, each gets its own 20-amp circuit per the appliance manual and NEC 422.4 (now E3805 in the 2021 IBC). A garbage disposal cannot share a circuit with the dishwasher, even if the loads are low. These details are easy to miss during plan design, so confirm with your electrician (or contractor) before submitting to the city. Glendale Heights will not approve a plan that violates this rule, and resubmission costs time (2+ weeks) and frustration.

Plumbing vent routing in Glendale Heights: trap arm, slope, and the vertical rise myth

When you relocate a kitchen sink more than a few feet from its current location, the vent routing changes, and this is where many remodels hit a snag. IRC P2722 (adopted by Illinois) specifies that the trap arm (the horizontal pipe from the trap to the vent) must slope downward toward the trap at a rate of at least 1/4 inch per foot. If the vent is 10 feet away horizontally, the vent must be at least 2.5 inches higher than the trap outlet. This is not a decorative detail; it prevents trap seal loss and siphoning. Glendale Heights requires a plumbing plan that shows this slope, and if your plan shows a trap arm that's level or slopes upward, it will be rejected. Many homeowners assume they can just run the vent up the wall above the island, but if the island is 8+ feet from the main wall vent, the trap arm must slope that entire distance.

The vertical rise from the trap to the vent stack is also critical. If the vent stack is right next to the trap (less than 2 feet away), the vertical rise can be minimal. But if the vent is on the opposite wall, the arm must slope for distance, then rise vertically to the main stack. The vent pipe diameter depends on the drainage load: a 1.5-inch trap (standard kitchen sink) typically uses a 1.5-inch vent, but if you're venting both the sink and dishwasher on the same vent, you may need a 2-inch vent. The plumbing plan must show all of this. Many DIY remodelers or inexperienced contractors assume they can 'just run a pipe up the wall,' but Glendale Heights inspectors will request a corrected drawing if the slope and sizing are wrong. This is the #1 plumbing-plan rejection in the city.

If the new sink location requires a new main vent stack through the roof, you're adding a second roof penetration. Glendale Heights will flag this and ask for roof flashing detail and proof that the vent is sized for the load (per the drainage load tables in ICC Chapter 25). If the kitchen is on the second floor of a colonial or bi-level, the vent must rise above the roof line and be at least 6-12 inches above the high side of the roof (if the slope is shallow), or 2 feet higher than any roof opening within 10 feet (per P3103.2). Plan for the roofer to coordinate with the plumber on flashing installation; this is an inspection point.
