Start with the correct local authority
Start by confirming both the jurisdiction and the public sewer system receiving the discharge. Los Angeles Municipal Code section 64.30 applies within the City and also to a person outside City limits who discharges into the City's publicly owned treatment works. A Los Angeles postal address can otherwise be in another incorporated city or an unincorporated area with a different sewer and FOG authority. Do not treat a City rule as a countywide rule for all 88 cities.
What the City of Los Angeles requires
City food service establishments must implement the City's FOG best management practices. A food service establishment required to hold an industrial-wastewater permit must install, operate, and maintain an approved, adequately sized, accessible gravity grease interceptor unless the Director grants a waiver.
New food service establishments and existing establishments with planned building modifications valued at $100,000 or more are subject to the City's gravity-interceptor requirement. The code includes waiver, variance, and alternative-device pathways, so confirm the project with the City before selecting or changing equipment.
Build maintenance around the approved device
Do not use a generic Los Angeles County cleaning interval. Follow the facility's permit conditions, approved equipment, manufacturer instructions, observed accumulation, and written direction from the responsible wastewater authority. Arrange service early enough to keep the device operating as approved and to prevent grease from reaching the sewer.
Keep service invoices and any maintenance, hauling, discharge, or disposal records required by the permit. Ask the local authority how long site-specific records must be retained rather than relying on a generic national period.
Compare written service quotes
The City does not publish a contractor price list. Compare written scopes that identify the device, access conditions, complete cleaning work, condition notes, scheduling, after-hours terms, handling of removed material, documentation, exclusions, and total price. Ask the contractor to identify the licenses, permits, insurance, and disposal documentation that apply to the specific job.
Keep fryer-oil collection separate from grease-interceptor service. A used-cooking-oil pickup arrangement does not establish the rules, price, or disposal route for interceptor waste.
A practical facility checklist
- Confirm the address, the sewer authority, and whether the discharge enters the City of Los Angeles treatment system.
- Keep the current industrial-wastewater permit and written device approval, if required.
- Follow the approved maintenance conditions and manufacturer instructions for the actual device.
- Request an itemized service record and the hauling or disposal documentation required for the job.
- Confirm City review before new construction, a qualifying major remodel, or an equipment change.
Frequently asked questions
Which FOG authority applies to my Los Angeles restaurant?
Confirm the address and the sewer system receiving the discharge. City rules apply within Los Angeles and can also apply outside City limits when a facility discharges to the City's publicly owned treatment works. Other systems may use a different authority.
Does a new or remodeled City of Los Angeles food business need a grease interceptor?
City rules subject new food service establishments and existing establishments with planned building modifications valued at $100,000 or more to gravity-interceptor requirements, with stated waiver, variance, and alternative-device processes. Confirm the plans with the City before construction.
How often should the device be cleaned?
Do not use a generic county schedule. Follow the facility's permit conditions, manufacturer instructions, observed accumulation, and current direction from the responsible wastewater authority.
What should a service company document?
Ask for an itemized receipt and the maintenance, hauling, and disposal documentation required by the facility's permit and local authority.
