Why You Need a Grease Trap/Interceptor Permit
You are legally required to obtain a Grease Trap/Interceptor Permit from the City of Grand Rapids Water System before operating any restaurant or food service establishment. This requirement is mandated by the City’s Sewer Use Ordinance (Chapter 147, Article V) and is enforced by the Public Works Department. The ordinance establishes strict limits on fats, oils, and grease (FOG) discharge into the municipal sewer system. Installing and maintaining a permitted grease interceptor is a condition of your water service connection, and you cannot receive final approval for your plumbing or occupancy inspections without this permit on file.
Operating without an approved grease trap or failing to maintain it can trigger immediate enforcement actions. Based on the city’s enforcement protocols, consequences include:
- Substantial Fines: Daily penalties for non-compliance, with amounts escalating for repeat violations.
- Service Disconnection: The city can shut off your water and sewer service until the violation is corrected, forcing a closure.
- Mandatory Remediation: You will be billed for the city’s costs to clean the sewer line blockage caused by your establishment, plus required cleaning and inspection of your interceptor.
- Permit & Inspection Holds: Your other city permits (like your Certificate of Occupancy) can be suspended or revoked, halting your ability to operate legally.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, Grand Rapids Public Works has integrated its grease trap permitting and inspection tracking into a centralized online portal, requiring all new applications and renewals to be submitted digitally.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | This type of establishment, defined as a "food service establishment" under Grand Rapids City Code §9.145, is required to have and maintain a properly sized and permitted grease trap/interceptor per the Michigan Department of Environment, Great Lakes, and Energy (EGLE) Rule 925. |
| Bar / Nightclub | Required | Required if the bar/nightclub has a kitchen that prepares and serves food, which then classifies it as a "food service establishment" under local code and triggers the EGLE Rule 925 requirement for a grease trap. |
| Food Truck | Required | A food truck operating in Grand Rapids is considered a mobile food service establishment and is required by city code to dispose of wastewater and grease through an approved method, which typically requires a connection to a commissary's permitted grease trap or holding tank. |
| Coffee Shop / Café | Not Required | Often exempt if operations are limited to brewing beverages and serving pre-packaged foods; a grease trap is not typically required as the primary wastewater does not contain fats, oils, and grease (FOG) from food preparation. |

24 of 29 auto-filledBusiness Name
textEnter the exact legal name of your restaurant or business as registered with the Michigan Secretary of State; this must match your articles of incorporation or DBA filing.
COMMON MISTAKE: Entering a trade name or 'doing business as' name that differs from the official registration, which will cause the city to flag the application for verification and delay issuance.
Business Phone
textEnter the primary, publicly listed phone number for the business location where the grease trap will be installed, formatted as (XXX) XXX-XXXX.
COMMON MISTAKE: Using a personal cell phone number instead of a dedicated business line, which complicates official communications and inspection scheduling from the city.
Street Address
textEnter the complete physical street address of the restaurant or food service facility where the grease trap will be installed, including suite or unit number if applicable.
COMMON MISTAKE: Entering a P.O. Box or mailing address instead of the physical location, which invalidates the permit because inspections are conducted on-site.
City
textThis field will be automatically populated as 'Grand Rapids' for all applications submitted to this jurisdiction.
COMMON MISTAKE: Manually entering a different city name, which confuses the routing of your application within the Public Works Department's review queue.
State
textThis field will be automatically populated as 'MI' or 'Michigan' to correspond with the Grand Rapids Public Works Department's jurisdiction.
COMMON MISTAKE: Manually entering an incorrect state abbreviation, which can cause application processing errors or misrouting.
Zip Code
textEnter the 5-digit ZIP Code for the restaurant's physical location; verify it using the USPS ZIP Code Lookup tool to ensure it matches the city's service area.
COMMON MISTAKE: Entering a ZIP+4 code or an incorrect ZIP code, which can trigger a geographic review to confirm the property is within Grand Rapids city limits.
Jobsite Contact Name
textEnter the full name of the person who will be physically present at the restaurant site during the grease trap installation for inspector access and questions.
COMMON MISTAKE: Listing a project manager or owner who will not be on-site, which causes failed inspections if the inspector cannot gain entry or speak to the responsible party.
Jobsite Contact Phone
textEnter the direct, reachable mobile phone number for the jobsite contact person to coordinate inspection visits, formatted as (XXX) XXX-XXXX.
COMMON MISTAKE: Providing an office main line that goes to voicemail, resulting in missed inspection calls, rescheduling fees, and project delays of 1-2 weeks.
Installer Type
textSpecify if the installer is a 'Licensed Plumber,' 'Registered Contractor,' or 'Property Owner' as defined by Grand Rapids Public Works, as each has different insurance and bonding requirements.
COMMON MISTAKE: Entering 'General Contractor' when a specific plumbing license is required, which halts the permit review until certified proof of licensure is submitted.
Contractor Name
textEnter the exact, registered business name of the plumbing or contracting company performing the installation, which must match their license or registration with the State of Michigan.
COMMON MISTAKE: Using a shorthand or nickname for the contractor that doesn't match their official license, triggering a mandatory verification request and adding 5-10 business days to the review.

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Submitting an Incorrect Drainage Plan Diagram
Applicants often hand-draw a simple sketch or submit a generic site plan, which the Grand Rapids Environmental Services Department rejects for lacking engineering details. This mistake adds 3-5 business days to your timeline, as you must engage a licensed professional to redraw it. Submit a scaled plumbing plan showing the exact location, pipe diameters, flow direction, and connection points to the municipal sewer line.
2. Miscalculating Grease Interceptor Capacity
Using the square footage of your kitchen or a rule-of-thumb estimate frequently leads to undersized interceptor calculations, a violation of the Michigan Plumbing Code § 1003.2. An undersized unit will fail inspection and force a costly replacement. Calculate capacity precisely using the total fixture unit (DFU) rating of all connected sinks, dishwashers, and floor drains as specified in the code.
3. Incomplete Maintenance Contractor Information
Leaving the 'licensed hauler' section blank or listing a company not pre-approved by the City of Grand Rapids causes immediate rejection. The city verifies the contractor's Wastewater Hauler License. Provide the company's full legal name, state license number, and a recent service contract. You can find the list of approved haulers on the Environmental Services website.

Complete plumbing permit application form with all required jobsite and installer information
Fill out the City of Grand Rapids Plumbing Permit Application, providing the restaurant's legal address, owner contact info, and the licensed plumbing contractor's state license number. Have your contractor's MI license and the property's parcel number ready. The most common error is using a contractor without a current Michigan license, which causes an immediate rejection.
Provide detailed description of grease trap/interceptor work in section III
In Section III (Description of Work), specify the grease trap manufacturer, model, capacity (in gallons), and the type of connection (new, replacement, or retrofit). Include the pipe material (e.g., PVC, cast iron) and diameter. Vague descriptions like "install grease trap" are the #2 cause of requests for clarification, adding 1-2 weeks to the review.
Determine scope of work and select applicable category
On the application, check the box for 'Grease Trap/Interceptor' under 'Scope of Work.' If replacing an existing unit, select 'Alteration'; for a new install in a building with existing plumbing, select 'New Construction.' Selecting the wrong category triggers a fee miscalculation and review delay.

See All RequirementsProcessing times vary significantly based on the complexity of your plumbing installation and the plan review queue at the Grand Rapids Building Safety Department. For a standard application tied to a Building Permit, review can take 2–4 weeks. Contact the Building Safety Department directly to confirm current wait times for your specific project.
The government filing fee ranges from $0 to $52, as posted on the Grand Rapids Building Safety Department fee schedule. The final cost depends on the valuation of the plumbing work; a separate plumbing permit fee is typically required. Not legal advice — verify exact costs with the Building Safety Department before submitting.
No, grease trap/interceptor permits are not transferable between locations. The permit is issued for a specific installation at a specific address. If you move or open a new location, you must apply for a new permit, which also requires a new site plan review and potentially a new Certificate of Occupancy.
The installation permit itself does not require renewal, but the system must be maintained in compliance. You are responsible for regular pumping and maintenance, and you must keep service records on-site for inspection. Annual inspections by the Building Safety Department may be required to verify ongoing compliance.
A city inspector will verify the grease interceptor is installed according to the approved plans, is the correct size and type for your facility, and is properly connected to the sanitary sewer. They will also check for required access points and labeling. Passing this final inspection is mandatory before the system can be put into service.
