First problem is zero lot line, but the gubbermint seems to believe I need a 1500 gallon grease trap/interceptor. It's impossible to put one of these in the ground. I'm used to seeing the smaller grease traps that fit under the sink, but they're wanting something 4'x8'. Any ideas? Second, is hanging a vent hood (the hood, not the hole-cutting in the roof and all that jazz) difficult? As anyone who's ever been through it can attest, build-out is horribly expensive and I'd love to save costs wherever possible.
