Without a Grease Trap/Interceptor Permit from Cincinnati's Division of Food Safety, your grease system cannot be inspected, certified, or legally operated—risking shutdown and fines for code violations. The Grease Trap/Interceptor Permit (also called a grease interceptor compliance letter or FOG control permit) is required by the City of Cincinnati for any food service establishment discharging grease into the municipal sewer system. Key facts:

Grease Trap/Interceptor Permit requirements in Cincinnati are governed by the Metropolitan Sewer District of Greater Cincinnati (MSD) under its Sewer Use Regulations, which implement Ohio EPA pretreatment standards codified in Ohio Administrative Code Chapter 3745-3. Any food service establishment that discharges fats, oils, and grease (FOG) into the public sewer system is required to install an approved grease interceptor or trap, obtain the corresponding permit before installation or modification, and maintain the device in compliance with MSD's grease discharge limits. The permit triggers inspections by MSD's Industrial Pretreatment Program, which verifies that your interceptor is properly sized, installed to plumbing code, and documented — before you connect to the municipal sewer system. Operating without this permit is not a paperwork technicality: Cincinnati's sewer use regulations treat unpermitted FOG discharge as a prohibited discharge violation, carrying enforcement consequences independent of whether an actual blockage has occurred.
Failing to obtain or maintain a Grease Trap/Interceptor Permit exposes your restaurant to a compounding set of operational and financial risks:
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2024, MSD Greater Cincinnati updated its FOG Control Program inspection frequency requirements, adding mandatory quarterly self-monitoring reporting for higher-volume food service establishments — contact MSD's Industrial Pretreatment Program to confirm whether your facility category triggers the new reporting schedule.
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Full-service restaurants generate significant fats, oils, and grease (FOG) from cooking operations and are required by Cincinnati MSD's Pretreatment Program (Cincinnati Municipal Code § 733-5) to install and permit a grease interceptor before connecting to the public sewer system. |
| Bar / Nightclub | Required | Bars and nightclubs that operate a kitchen or prepare food — including bar snacks, appetizers, or full menus — must obtain a grease trap permit under Cincinnati MSD's FOG Control Program, as any food-preparation sink or dishwasher discharging grease-laden wastewater triggers the requirement. |
| Food Truck | Required | Food trucks operating in Cincinnati must comply with FOG control requirements and are typically required to use an approved grease interceptor or holding tank at their commissary kitchen; Cincinnati MSD requires the commissary facility — not the truck itself — to hold the permit, so the food truck operator must confirm their commissary is permitted before operating. |
| Coffee Shop / Café | Required | Coffee shops that operate espresso machines, dishwashers, or any food-preparation equipment discharge FOG into the sewer system and are subject to Cincinnati MSD's grease interceptor permit requirement, even if cooking operations are minimal. |

See Full Requirements →Check this box if your facility includes refrigerated or freezer warehouse storage space — this affects grease load calculations and interceptor sizing requirements reviewed by Cincinnati MSD.
COMMON MISTAKE: Operators sometimes skip all warehouse type checkboxes when warehouse space doubles as prep or thaw space — if refrigerated units are present anywhere on the premises, this box must be checked.
Check this box if your facility stores non-perishable dry goods inventory in a dedicated warehouse area — reviewers use this to confirm no additional drain connections require interceptor coverage.
COMMON MISTAKE: Leaving this unchecked when dry storage is connected to floor drains that route to the sanitary sewer can trigger a request for supplemental drainage diagrams, adding weeks to your review.
Check this box if your warehouse space does not fit either the refrigerated or dry goods categories, and be prepared to describe the storage type in any accompanying narrative field — Cincinnati MSD reviewers flag 'Other' selections that lack a written explanation.
COMMON MISTAKE: Checking 'Other' without providing a written description in the associated comment field is a common source of reviewer follow-up requests that can delay approval by 1–2 weeks.
Check this box if your food service facility is located within a strip mall where units share a common wall — this classification affects shared lateral and interceptor placement rules under Cincinnati MSD's pretreatment program.
COMMON MISTAKE: Confusing a strip mall (attached, shared wall) with a standalone outparcel in the same shopping center is a frequent error; selecting the wrong location type can result in incorrect interceptor sizing guidance from the reviewer.
Check this box if the food service operation is located within a K–12 school or educational campus — school-based facilities are subject to separate grease interceptor sizing criteria based on meal counts rather than seat counts.
COMMON MISTAKE: Operators running catering or food service contracts inside school buildings sometimes select 'Other' location types instead of 'School,' which routes the application to the wrong review queue at Cincinnati MSD.
Check this box if your food service operation is inside a stadium, arena, or amusement park — these high-volume, event-driven venues require oversized interceptors and may need a separate pretreatment capacity study submitted to Cincinnati MSD.
COMMON MISTAKE: Operators in stadium concourse or vendor stalls sometimes select 'Mall/Food Court' instead, which understates expected grease load and can result in an undersized interceptor specification being rejected during plan review.
Check this box if your food service operation is located within or attached to a supermarket — deli, bakery, and prepared foods departments in supermarkets are classified separately due to continuous high-volume grease discharge.
COMMON MISTAKE: Supermarket operators with multiple food prep departments sometimes only submit one interceptor permit application when separate fixtures serving different departments may each require individual review — contact Cincinnati MSD to confirm whether a single application covers the entire facility.
Check this box if your restaurant occupies a freestanding building with no shared walls — this is the most common classification for Cincinnati food service operators and sets the baseline interceptor sizing formula used during plan review.
COMMON MISTAKE: Operators in end-cap units of a strip mall (sharing one wall) frequently check 'Stand-alone Restaurant' instead of 'Strip Mall (attached),' which is one of the higher-frequency misclassification errors and will trigger a correction request from Cincinnati MSD reviewers.
Check this box if your food service operation is inside an enclosed shopping mall or food court — these facilities often use a shared interceptor managed by the property owner, and Cincinnati MSD will require documentation of shared interceptor capacity as part of the permit review.
COMMON MISTAKE: Food court tenants who assume the mall's shared interceptor covers their individual permit are frequently surprised when MSD requires tenant-specific discharge calculations — confirm shared interceptor documentation with your property manager before submitting.
Check this box if the food service operation is the kitchen for a licensed nursing home or long-term care facility — these operations are subject to Ohio EPA and Cincinnati MSD dual-authority review due to the healthcare facility classification.
COMMON MISTAKE: Applicants for assisted living facilities (which are not licensed nursing homes) sometimes select this option incorrectly — verify your facility's Ohio Department of Health license classification before checking this box to avoid a jurisdiction mismatch that delays review.

The most common rejection trigger is submitting interceptor sizing calculations that don't match Cincinnati MSD's required design criteria — either using an outdated sizing method or pulling numbers from equipment spec sheets instead of performing the site-specific flow rate calculation MSD requires. For example, listing a 1,000-gallon interceptor based on a manufacturer's general recommendation rather than the calculated peak flow from your kitchen fixture units will result in an immediate correction request. Verify your sizing calculations against MSD's current Grease Interceptor Design Standards before submission; a rejected sizing calculation typically adds 3–4 weeks to your approval timeline.
MSD reviewers require a scaled site plan or plumbing diagram that clearly shows the interceptor's location relative to the building, the fixture connections draining into it, the discharge line routing to the sewer, and the access point for inspection and maintenance. Submitting a freehand sketch, a floor plan without dimensions, or a plan that omits the discharge connection to the public sewer lateral is one of the most frequent causes of incomplete-application notices. Use a licensed plumber or engineer to prepare this drawing and confirm it includes all required labels — missing a single labeled element can send your application back and add 2–3 weeks to processing.
The business name and owner/operator information on the permit application must exactly match the entity registered with the Ohio Secretary of State and the name on your Cincinnati business license — a discrepancy as minor as 'LLC' vs. 'Limited Liability Company' or a DBA name used instead of the legal entity name will cause MSD to flag the application for correction. For example, entering 'Riverfront Tacos' when your registered entity is 'Riverfront Restaurant Group LLC' is a common error that requires resubmission. Pull your exact legal entity name from your Ohio Secretary of State filing before completing the application.

Contact the Cincinnati Department of Health or your local health district to confirm the required capacity and type of grease trap for your restaurant based on your kitchen equipment, menu, and projected waste volume. Bring your restaurant's floor plan, equipment list, and expected daily patron count. Most restaurants require 500–2,000 gallon traps depending on cooking volume — undersizing is the #1 reason permits get rejected at inspection.
Select a licensed plumber or grease trap installer certified to work in Cincinnati — the city requires all installation work to be performed by licensed professionals. Verify their current license status through the Ohio Construction Industry Licensing Board. Get a written quote that includes the trap model, capacity, materials, labor, and compliance with Cincinnati Plumbing Code § 55-101.
File your grease trap installation permit application with the Cincinnati Building Services Division (address: 635 Eden Park Drive, Cincinnati, OH 45202, or submit online through the city's ePermitting portal if available).

See All RequirementsProcessing timelines vary depending on whether your installation requires plan review and inspection, per the Cincinnati Department of Transportation & Engineering (DOTE) website. Most permits are issued within 2–4 weeks of application submission if all documentation is complete and the installation meets code; however, applications requiring modifications or additional inspections may take 4–8 weeks. Contact the Cincinnati DOTE Plumbing Section at (513) 352-3810 to confirm the current timeline for your specific project.
Cincinnati does not charge a separate government filing fee for grease trap/interceptor permits, per the city's fee schedule. However, you may incur costs for required plan review, inspection fees (if applicable), and equipment installation or modifications to meet code standards. Contact Cincinnati DOTE or your licensed plumber to confirm any applicable fees for your installation.
No—grease trap/interceptor permits are tied to a specific installation address and cannot be transferred to a new location. If you relocate your restaurant, you must obtain a new permit for the grease trap/interceptor system at the new address and submit it alongside your Certificate of Occupancy application. Contact Cincinnati DOTE to confirm the transfer process and any required documentation for your move.
Grease trap/interceptor permits in Cincinnati are not annually renewed; instead, your system must pass required inspections and remain in compliance with Cincinnati Code § 1053 standards. You must maintain service records and schedule inspections as required by your system manufacturer or when Cincinnati DOTE mandates reinspection. For compliance details, contact Cincinnati DOTE or consult your Building Permit conditions.
During inspection, a Cincinnati DOTE plumbing inspector will verify that your grease trap/interceptor is sized correctly, installed per code (Cincinnati Code § 1053), properly vented, and equipped with accessible cleanout ports for maintenance. The inspector will confirm that your system does not discharge directly to the public sewer without proper treatment and that access for pumping and cleaning is unobstructed. If deficiencies are found, you will receive a correction notice and must reschedule inspection after repairs are completed.
