The Uniform Plumbing Code (UPC) does not permit a grease interceptor to serve as a fixture trap and also prohibits the installation of a vent between the air intake on the flow control and the grease interceptor. Like HGIs, they can be recessed in the floor, located on the floor below, or sit on the floor next to a single fixture.

GREASE INTERCEPTORS - Zurn Where large central grease interceptors are entirely impractical, such as my old stomping ground of New York City, localized interceptors become the most practical solution. Most inspectors would say yes because the unit itself is trapped and a trap needs a vent, but if you ask the inspectors in Los Angeles City, they would say no, due to the fact that each fixture upstream of the trap is individually vented.
