I'm planning an outdoor BBQ island with a simple sink with cold water for handwashing. My city defers most code to California's code but in both cases I'm having trouble finding the relevant section. One reference says "drains must be tied to the house's drainage system and must be covered [roof] to avoid rainwater using the house's drainage" (words to that effect). It seems excessive for a BBQ island though, especially as I didn't plan a roof (which does require a permit, an added hassle both for the permit and the roof itself).
The simplest solution is a buried bucket with holes in the bottom and filled with small stones, or a French drain, but those doesn't seem to be allowed... or are they? Or maybe an outdoor sink with a cover?
The problem is, the BBQ island is lower than the ground floor in the house, and a drain line would have to dive under existing concrete pads (even lower). The septic tank is on the opposite side of the house. The road outside does not have drains either - runoff just flows onto our property and our neighbors'.
Any ideas where I can find this in CA code - or an exemption to it? From there I might be able to locate it in my city's code. The city were not responsive to an unrelated previous question. Thanks.
