Health inspections in California are not something you prepare for the night before. The restaurants that consistently pass with high scores are the ones where compliance is built into daily operations, not scrambled together when the inspector walks through the door.
Grease management is one of the most commonly cited areas during inspections, and it covers more than just the grease trap. Inspectors look at your documentation, your kitchen practices, your exhaust system, and your waste oil storage. This guide covers every grease-related item they check so you can be ready at all times.
The Complete Grease Inspection Checklist
Health inspectors follow a structured checklist during every visit. Here is what they look at, organized by area.
Grease Trap / Interceptor
- Maintenance log is current. The inspector will ask to see your log showing the date, hauler name, and amount of waste removed for each pumping. Gaps in the log raise red flags.
- Trap is not at or near capacity. If the grease layer is visibly thick or nearing the one-quarter threshold, it will be noted.
- No overflow or signs of recent overflow. Grease stains around the trap access, on the floor, or on adjacent walls indicate past overflows that were not properly addressed.
- Access point is clear and accessible. The trap lid must be accessible. Inspectors cannot verify maintenance if the trap is blocked by equipment, storage, or debris.
- Proper sealing. The trap lid should sit flush and be properly sealed to prevent odors and vermin access.
Kitchen Hood and Exhaust System
- Current hood cleaning certificate. This is a document from a certified hood cleaning company showing the date of the last professional cleaning. It should match the NFPA 96 schedule for your cooking type.
- Filters are clean. Baffle filters in the hood should be free of heavy grease buildup. Most restaurants run these through the dishwasher weekly or have a set rotation.
- No grease dripping. Visible grease drips from the hood, the duct openings, or the rooftop fan housing are a violation and a fire hazard.
- Grease cups or troughs are emptied. The collection cups at the bottom of the hood filters should be emptied daily or as needed.
Waste Oil Storage
- Containers are labeled. Your used cooking oil collection containers should be clearly labeled as waste oil or UCO.
- Containers are sealed. Lids must be securely closed when not actively being filled to prevent spills, pests, and odors.
- No overfilling. Containers should not be filled to the brim. Leave at least two inches of headspace.
- Secondary containment. If your containers are stored outdoors, they should be in an area with secondary containment (a lip, berm, or tray) to catch spills.
- Area is clean. The ground around the containers should be free of spilled oil, food debris, and standing water.
Kitchen Floor and Drain Areas
- Floor drains are clear. No standing grease or water around floor drains. Drain covers should be in place and not caked with grease.
- Behind equipment is clean. Inspectors will look behind the fryer, flattop, and other grease-producing equipment for accumulation.
- Mats and walking surfaces. Anti-slip mats near fryers and cooking stations should be clean, not saturated with grease.
Documentation
- Grease trap pumping manifests. These are the official CDFA documents showing each waste load was transported by a licensed hauler to an approved facility.
- Hood cleaning certificate. Current and from a certified provider.
- Grease trap maintenance log. A running record of all service dates and details.
- Staff training records. Some jurisdictions check whether employees have been trained on proper grease disposal. Even if not required, having this documented shows diligence.
Violations: What Gets Cited and How Severe
Not all grease-related violations carry the same weight. Understanding the difference helps you prioritize what matters most.
Critical Violations (Immediate Correction Required)
- Active grease trap overflow
- Grease discharge to the storm drain system
- No grease trap installed when required by code
- Extreme grease buildup creating a fire hazard on exhaust systems
Major Violations (Correction Within Set Timeframe)
- Grease trap at or above the one-quarter capacity threshold
- Missing or expired hood cleaning certificate
- No maintenance log or significant gaps in records
- Waste oil containers without lids or secondary containment
Minor Violations (Noted, Correction Expected)
- Grease accumulation on floor behind equipment
- Dirty hood filters between professional cleanings
- Missing labels on waste oil containers
- Grease cups on hood not recently emptied
Monthly Self-Inspection Protocol
The easiest way to guarantee you pass every inspection is to inspect yourself monthly. Walk through the same checklist the inspector uses. Here is a simplified monthly routine:
Week 1: Documentation audit. Pull your grease trap maintenance log and verify all entries are current. Check that you have manifests for every pumping. Verify your hood cleaning certificate is not expired.
Week 2: Trap area inspection. Open the trap access and visually check the grease level. Inspect the area around the trap for any signs of leakage or overflow. Verify the access point is not obstructed.
Week 3: Kitchen walkthrough. Check behind fryers and cooking equipment. Inspect floor drains. Look at hood filters and grease cups. Walk the waste oil storage area.
Week 4: Staff check-in. Briefly review grease disposal procedures with kitchen staff during a pre-shift meeting. Reinforce dry-wiping, plate scraping, and proper oil disposal.
This four-week rotation takes about 15 minutes per week and eliminates the anxiety of unannounced inspections entirely.
What to Do When the Inspector Arrives
When a health inspector arrives at your restaurant, the best response is calm professionalism. Here is how to handle the grease-related portions:
Be ready with your binder. Keep your maintenance log, manifests, and hood cleaning certificate in a single binder near the manager station. Hand it to the inspector immediately when they ask for records.
Walk with the inspector. Accompany them through the kitchen. If they find an issue, acknowledge it and explain what corrective action you will take and by when.
Do not argue about the findings. If something is cited, note it and fix it. Arguing rarely changes the outcome and can negatively affect the inspector's overall impression.
Ask questions. If you are unclear about a requirement or a citation, ask the inspector to explain it. Most are happy to educate rather than just penalize.
The Bottom Line
Passing the grease-related portions of a health inspection is not about last-minute preparation. It is about maintaining a clean, well-documented operation every day. The checklist in this guide mirrors what inspectors look at, so if you review it monthly and address issues as they appear, the actual inspection becomes a formality rather than a source of stress.
