Interested in hearing how other inspectors would report this trap configuration.

If that's a "T" with a baffle, then it shouldn't be a problem.

I put a few inches of water in both sinks, pull the plugs and then turn on the disposal. If the disposal pushes water into the adjacent sink bowl (most of the time), then I mention it in my report and advise corrections by a licensed and qualified plumbing contractor.

Really sage advice Gunnar. Cuts through codes & red tape - - - it works or it don't.

it looks acceptable codewise.

That combintion requires minimum 1-1/2" drain/waste plumbing. Using 1-1/4 is never allowed for other than a lavatory.

DFU for DW, GD & double sink.

The lateral from the double sink on the right is not correct (downhill and extended slip). Slip joints for other than the trap on lateral (horizontal still requires minimum slope) are not allowed. That is not Sch. 40 or better - those are Sch. 10 or 20 DIY kit pieces. You may not reduce the trap size. Incorrect fittings (size, type, configuration) incorrect application, not approved for purpose. Sadly it is not illegal to sell this material, only to employ (install, use) it.

The drywall opening has not been closed, neither around the plumbing nor the electrical box (presumed behind the wall plate). This is both a pest/health, general property maintenance/fire resistant construction, and electrical code issue.

The cord is not an approved, length-etc. set, and has been coiled around the waste/drain plumbing.

The spray hose has been run so as to catch on the trap arm and electrical cord/plug set.

It is not right for CA building, plumbing, electrical, or property maintenance codes.
