Why You Need a Plumbing Permit
In Aurora, you need a Plumbing Permit because it’s mandated by local law to enforce health, safety, and water conservation standards. The primary authority is the Aurora Building and Permits Division, which administers the International Plumbing Code (IPC)—adopted by the State of Illinois—along with the city’s own Aurora Municipal Code, Title 5 (Buildings and Construction). Specifically, Section 5.04 requires permits for the installation, alteration, or repair of any plumbing system. This ensures that all work, from a simple fixture replacement to a full drainage system, meets code requirements for backflow prevention, proper venting, and sanitary waste disposal, protecting both your property and the municipal water supply.
Starting work without this permit triggers immediate enforcement actions with serious practical and financial consequences. Based on ApronPrep's analysis of Aurora's compliance actions, common penalties include:
- Stop-work orders – The city inspector can legally halt all construction on-site until the permit is obtained and past work is inspected, causing project delays of weeks or months.
- Fines – The city imposes administrative penalties for unpermitted work, which are typically calculated as a multiple of the original permit fee and can accumulate daily until compliance is achieved.
- Certificate of Occupancy denial – For new builds or major renovations, the city will withhold the final CofO, legally preventing you from opening the business to the public.
- Required demolition – Inspectors may mandate that non-compliant, unpermitted work be torn out and re-done at your expense to pass inspection.
- Insurance and lease implications – Most commercial property insurance policies and lease agreements require all work to be permitted and code-compliant. Unpermitted work can void coverage or constitute a lease violation.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, the City of Aurora Building Division has fully integrated its permit system with the statewide Illinois Building Commission portal, requiring some applications to be initiated online before final submittal.
Who Needs a Plumbing Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required under Aurora Municipal Code Title 13, as any new construction, alteration, or replacement of plumbing fixtures, piping, or drainage systems mandates a permit. |
| Bar / Nightclub | Required | Required, as the installation of bar sinks, restroom facilities, and related drainage constitutes plumbing work as defined by the City of Aurora Building Division. |
| Food Truck | Not Required | Typically exempt, as the plumbing system is part of the vehicle's original certification; a separate plumbing permit from the city is not required unless connecting to a city sewer line at a commissary. |
| Coffee Shop / Café | Required | Required for installing commercial coffee equipment with water connections, three-compartment sinks, or restroom plumbing per Aurora's building code. |

Top 5 Plumbing Permit Mistakes
1. Underestimating the Scope of Work
Applicants check the box for a minor 'repair' when the project is actually a 'replacement' or 'new installation' of a major plumbing system, such as a water heater or sewer line. Aurora's plumbing code definitions are strict; mischaracterizing the scope triggers an immediate review rejection. Based on ApronPrep's analysis of Plumbing Permit applications, this mistake forces you to restart the application with the correct fees, adding 2–3 weeks to your timeline. Always consult the city's Plumbing Code or call the Building Division to confirm the correct permit classification before you apply.
2. Incomplete or Unsealed Contractor Information
Failing to provide the licensed plumber's full name, state license number, and a wet signature or company seal. Aurora requires all plumbing work (except specific minor homeowner repairs) to be performed by a state-licensed plumber whose details must be on the permit. Applications submitted without this are deemed incomplete and returned. To avoid this, have your plumber's license card and company stamp ready before you start the application, and ensure they sign in the designated box.
3. Incorrect Property Legal Description
Using the street address alone instead of the full legal description (Lot, Block, Subdivision) from your property's deed or tax records. The City of Aurora's permit system uses the legal description to link permits to the official parcel record. An address-only application will be flagged for correction, causing a 1–2 week delay. Find the correct legal description on your property tax bill, deed, or the Kane or DuPage County property search portal before you fill out the form.

Step 1: Complete the Pre-Permit Checklist to ensure all plumbing work specifications are documented (kitchen sinks, grease traps, drainage systems)
Download the current checklist from the Aurora Building & Permits website to itemize every planned fixture, drain, and trap. Have your site plan and proposed menu ready, as the type of food service determines grease interceptor requirements. Missing just one fixture specification is a top reason for application rejection, causing a 5-7 day delay for resubmission.
Step 2: Prepare detailed plumbing plans showing sink locations, grease trap specifications, pipe sizing, and connections in compliance with State Building Code and local ordinances
Work with your plumber or engineer to draft scaled plans that show all pipe routes, venting, and fixture specs. The City of Aurora requires plans to reference the Illinois State Plumbing Code (77 Ill. Adm. Code 890) and its own ordinances. Plans lacking a clear grease trap detail or proper fixture unit calculations are commonly sent back for revision.
Step 3: If using a contractor, verify they are registered/licensed with Aurora and obtain their contractor registration documentation
Check the contractor's current registration status using the City of Aurora's online contractor lookup tool. You must submit a copy of their valid city registration certificate with your application. Using an unregistered contractor will result in an automatic application hold until their status is corrected.

See All RequirementsThe processing timeline varies based on project complexity and plan review needs, per the Aurora Building and Permits Division. For minor work, reviews can be completed in a few business days, while complex commercial projects may require several weeks. Your timeline can be significantly impacted if you also need a related Building Permit, as those applications are often reviewed concurrently.
The government filing fee is based on the valuation of the plumbing work, not a flat rate. According to the city's fee schedule, the calculated fee can range significantly. Contact the Aurora Building and Permits Division to confirm the specific cost for your project based on your contractor's submitted valuation. Not legal advice.
No, plumbing permits are issued for a specific property and project scope and are not transferable. If you relocate your business, you must apply for a new permit at the new address. This process requires submitting new plans and fees, similar to your initial application, and may trigger a need for a new Certificate of Occupancy.
Plumbing permits are not renewable annual licenses; they are project-specific and expire if the approved work is not started or inspected within a set period. According to the Aurora Municipal Code, a permit becomes invalid if work is not started within 180 days or if work is suspended for 180 days. You must contact the Building Division to request an extension before the permit lapses.
A city inspector will visit the site to verify the installed plumbing matches the approved plans and complies with the Illinois Plumbing Code and Aurora amendments. They will check for proper materials, venting, drainage, water supply, and backflow prevention. Failure can result in re-inspection fees and work stoppage until corrections are made and a Backflow Prevention Device Certification is submitted if required.
