Plumbing Permit in Chicago, Illinois (2026)
Without a Plumbing Permit from the Chicago Department of Public Health, your restaurant cannot legally install, modify, or repair any plumbing system—and inspectors can issue violations or halt construction. The Plumbing Permit (also called a plumbing installation permit or water/sewer work permit) is required by the City of Chicago for any plumbing work within your establishment. Key facts:

Why You Need a Plumbing Permit
Chicago requires a Plumbing Permit for any new plumbing installation, alteration, or repair that affects the building's drainage, water supply, or venting systems. The requirement is grounded in the Chicago Plumbing Code (Title 18-29 of the Municipal Code of Chicago), which adopts and locally amends the Illinois Plumbing Code as administered by the City of Chicago Department of Buildings. Work performed without a permit is considered an unlawful building violation under Title 13-12 of the Municipal Code. The permit process ensures that a licensed plumber of record pulls the permit, plans are reviewed for code compliance, and a city inspector signs off on the finished work — steps that protect your Certificate of Occupancy and your ability to open for business.
Operating without a required plumbing permit exposes your restaurant to serious legal and financial consequences that can delay or permanently halt your opening. The Department of Buildings has broad authority to act immediately upon discovering unpermitted work. Documented consequences include:
- Stop-work orders — all construction activity must cease until the violation is resolved, potentially freezing your entire buildout timeline
- Fines and administrative penalties — the Department of Buildings can issue daily fines for continued violations; contact the Department of Buildings directly to confirm current fine schedules, as amounts are set administratively and subject to change
- Certificate of Occupancy denial — the city will not issue a CO for a space with open plumbing violations, meaning you legally cannot open to the public
- Mandatory demolition of non-compliant work — inspectors can require unpermitted plumbing to be exposed, inspected, and potentially torn out and rebuilt to code at your expense
- Insurance and lease implications — most commercial property insurance policies exclude coverage for damage caused by unpermitted work; your landlord's lease addendum may also treat unpermitted construction as a default event
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2025, the Chicago Department of Buildings expanded its online permit portal to accept electronic plan submissions for a broader category of plumbing projects — reducing the need for in-person filing for many standard restaurant buildout scopes; contact the Department of Buildings to confirm whether your specific project qualifies for the expedited e-permit pathway.
Who Needs a Plumbing Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Any new construction, renovation, or modification to plumbing fixtures — including sinks, grease traps, dishwashers, and floor drains — requires a Plumbing Permit from the City of Chicago Department of Buildings under Chicago Building Code Title 18-29 (Chicago Plumbing Code). |
| Bar / Nightclub | Required | Bars and nightclubs that install or modify plumbing for bar sinks, ice machines, or glass washers must obtain a Plumbing Permit under Chicago Building Code Title 18-29, as any new or altered plumbing connection to the public water or sewer system requires city review. |
| Food Truck | Not Required | Food trucks are mobile units regulated under the Chicago Department of Business Affairs & Consumer Protection mobile food dispenser license framework — fixed plumbing permits from the Department of Buildings are not required because food trucks do not connect to the city's permanent water or sewer infrastructure. |
| Coffee Shop / Café | Required | Installing espresso machines, commercial dishwashers, or additional hand-wash sinks triggers a Plumbing Permit requirement under Chicago Building Code Title 18-29, as each new fixture connection to supply or drain lines requires a licensed plumber to pull a permit. |

12 of 14 auto-filledLegal Business Name
textEnter the exact legal name of your business as it appears on your Illinois Secretary of State registration or your DBA filing — no abbreviations, trade names, or nicknames.
COMMON MISTAKE: Entering a trade name (e.g., 'Joe's Diner') instead of the registered legal entity name (e.g., 'Josephine Restaurant Group LLC') causes a mismatch with city business records and triggers manual review.
Federal EIN
textEnter your 9-digit Employer Identification Number issued by the IRS in the format XX-XXXXXXX — this is used by the Chicago Department of Buildings to verify your business entity.
COMMON MISTAKE: Entering a Social Security Number instead of a Federal EIN, or omitting the hyphen (e.g., '123456789' instead of '12-3456789'), will cause a data validation failure.
Business Owner Name
textEnter the full legal name (first, middle initial if applicable, last) of the individual owner or the authorized officer of the business entity listed on the permit application.
COMMON MISTAKE: Using a nickname or an abbreviated first name instead of the full legal name as it appears on a government-issued ID can cause a discrepancy during identity verification.
Owner Phone Number
textEnter a direct, reachable U.S. phone number for the business owner in the format (XXX) XXX-XXXX — the Chicago Department of Buildings may use this number to schedule inspections or request missing documents.
COMMON MISTAKE: Entering an extension-only number or a number that belongs to a contractor rather than the owner can delay inspection scheduling and add days to your timeline.
Owner Email Address
textEnter a valid, actively monitored email address for the owner — the city's online permit portal (Chicago PERMITS) sends status updates, deficiency notices, and approval confirmations to this address.
COMMON MISTAKE: Using a shared or infrequently checked email address (e.g., a general 'info@' inbox) means critical deficiency notices can go unread, causing your application to expire before you respond.
Property Address
textEnter the full Chicago street address of the property where plumbing work will occur, including street number, street name, unit or suite number if applicable, city (Chicago), state (IL), and ZIP code — this must match the Cook County Assessor's property record exactly.
COMMON MISTAKE: Entering a mailing address, a P.O. Box, or the owner's home address instead of the physical restaurant address is one of the most frequent causes of outright rejection on Chicago plumbing permits.
Type of Food Service Establishment
textEnter the specific category of food service establishment (e.g., 'full-service restaurant,' 'limited food preparation facility,' 'shared kitchen,' or 'food truck commissary') as defined under Chicago Municipal Code Title 4-8 — this classification determines which plumbing fixture counts and grease interceptor requirements apply.
COMMON MISTAKE: Selecting a generic category like 'restaurant' when the operation qualifies as a 'shared kitchen' or 'catering facility' can trigger a code-compliance mismatch, requiring amended plans and adding 2–4 weeks to approval.
Food Preparation Activities Description
textProvide a specific, plain-language description of all food preparation activities conducted on-site (e.g., 'raw meat butchering, hot food cooking, cold food assembly, dishwashing'), as this determines grease interceptor sizing and three-compartment sink requirements under Chicago Plumbing Code § 18-29.
COMMON MISTAKE: Writing a vague description like 'standard restaurant operations' instead of itemizing specific activities gives plan reviewers insufficient information to verify fixture compliance, commonly triggering a Request for Information (RFI) that pauses your application.
Food Service Manager Name
textEnter the full legal name of the designated Food Service Manager — this person must hold a valid Illinois Food Service Sanitation Manager Certification and their name must match exactly what appears on that certificate.
COMMON MISTAKE: Listing a manager who has not yet completed their Illinois FSSMC certification, or whose name is spelled differently than on their certificate, will cause a cross-reference failure during document review.
Food Safety Certification Details
textEnter the full certification details for the Food Service Manager's Illinois Food Service Sanitation Manager Certification (FSSMC), including the certifying body (e.g., ServSafe, Prometric), certificate number, and expiration date in MM/DD/YYYY format.
COMMON MISTAKE: Entering an expired certification date or omitting the certificate number forces a manual verification step with the Illinois Department of Public Health, which typically adds 1–2 weeks to processing time.

Top 5 Plumbing Permit Mistakes
1. Submitting Without a Licensed Illinois Plumber's License Number
Chicago requires all plumbing work to be performed and permitted by a licensed plumber holding a valid Illinois plumber's license — entering an unlicensed contractor's information or leaving the license field blank triggers an automatic rejection. For example, entering a general contractor's license number instead of a State of Illinois licensed plumber's number will void the application entirely. Verify the plumber's license status on the Illinois Department of Public Health license lookup tool before submitting, and confirm the license is current for 2026 — expired licenses cause the same rejection as no license.
2. Using an Incorrect or Incomplete Property Index Number (PIN)
The Cook County Property Index Number (PIN) must match exactly what is on file with the Cook County Assessor — a transposed digit or missing segment causes the Department of Buildings to reject the application as unverifiable. For example, entering '14-21-300-001' instead of the correct '14-21-300-001-0000' (the full 14-digit format Chicago requires) is a common formatting error that adds 2–3 weeks to your timeline. Look up the full 14-digit PIN at the Cook County Assessor's website (cookcountyassessor.com) before you fill out the form.
3. Misclassifying the Scope of Work
Chicago's Department of Buildings distinguishes between permit categories — such as new installation, repair, replacement, and sewer work — and selecting the wrong category routes your application to the wrong review queue, delaying approval by 3–6 weeks. A common example: describing a full sewer line replacement as a 'repair' to avoid a higher fee tier, which reviewers flag during plan review and return for reclassification. Read the scope definitions in the Chicago Building Code (Title 14E) carefully, or contact the Department of Buildings permit help desk at 312-744-5000 to confirm the correct category before submitting.

Contact Chicago Department of Public Health's Food Protection Division
Call the Food Protection Division at (312) 747-9884 or visit their office at 121 N. LaSalle St., Room 500 to confirm current processing times and ask which application portal (online or paper) they're accepting. Processing timelines vary by season — expect 4–8 weeks during peak periods (spring/summer) and 2–4 weeks during slower months. Have your restaurant's address and intended opening date ready.
Complete Retail Food Establishment License application
Fill out the Chicago Department of Public Health Retail Food Establishment License application (Form [verify form number with department]) with your restaurant's legal name, address, ownership structure, menu category (limited food service, full-service, etc.), and proposed hours of operation. The form requires 34 fields total — ApronPrep auto-fills 28 from your business profile. Most applicants complete this section in 10–15 minutes.
Submit required documentation to Department of Public Health
Gather and submit the application packet: completed license form, floor plan (to scale, showing food prep areas, restrooms, and handwashing stations), current ServSafe or Food Handler Certificate for the permit holder, proof of liability insurance, and a copy of your lease or proof of occupancy. Submit via the department's online portal if available, or deliver in person to 121 N. LaSalle St., Room 500 with a stamped receipt as proof. The missing floor plan is the #1 cause of rejection — ensure it clearly labels all prep, cooking, and storage zones.

See All RequirementsContact the Chicago Department of Buildings for an estimated processing time, as review timelines vary based on project complexity and current application volume. Most standard plumbing permits for restaurant installations are processed within 2–4 weeks once submitted with complete documentation, though expedited review may be available for an additional fee. Processing time does not include the time required for inspections after permit approval.
The Chicago Department of Buildings does not charge a separate filing fee for plumbing permits — however, you may incur costs for required inspections, plan review services, or expedited processing. Verify current fee schedules and any inspection-related charges directly with the Department of Buildings, as costs may vary by project scope. Not legal advice — confirm all applicable fees with the Chicago Department of Buildings before submitting your application.
No, plumbing permits are location-specific and cannot be transferred to a different address or property. If you relocate your restaurant or expand to a new location, you must apply for a new Building Permit and a new plumbing permit with the Chicago Department of Buildings. Contact the Department of Buildings to confirm transfer policies for specific project scenarios.
Plumbing permits do not require renewal — they are issued once for a specific project and remain valid upon permit completion and final inspection approval. However, if you make significant modifications to your plumbing system after initial approval, you may need to file an amendment or new permit. Contact the Chicago Department of Buildings to determine whether your planned modifications require a permit amendment or new application.
A Chicago Department of Buildings inspector will verify that all plumbing work complies with the Chicago Plumbing Code, including proper installation of water supply lines, drainage systems, and backflow prevention devices. The inspector will check for code violations and may require corrective work before issuing final approval. If your restaurant requires a Backflow Prevention Device Certification, the inspector will verify that device installation meets municipal requirements.
Most routine repairs (replacing a faucet, fixing a leak) do not require a permit, but significant modifications to water supply, drainage, or sewer connections do. Per the Chicago Department of Buildings guidelines, any work affecting your restaurant's main water line, grease trap, or sewage system requires a plumbing permit. Contact the Department of Buildings or your licensed plumber to confirm whether your specific work scope requires a permit.
