What are those two regulations? The California Electrical Code 2010 has that no point on the wall space behind a countertop can be more than 600mm (24in) away from an outlet, which actually means an outlet every 4 feet (2 feet space are allowed either side) (Article 210.52). I don't see 18 in in there. There's a good diagram of the regulations here: http://buildingincalifornia.com/wp-content/uploads/2014/01/ResKitchenReceptacles.pdf http://buildingincalifornia.com/wp-content/uploads/2014/01/R... ... but there's similar drawings explaining this in the code itself. I'm not doubting that there's weird inconsistencies in the rules, but the 18in thing struck me as weird from my own experience of remodelling my house recently, so I looked up the CA code. Apparently SF are still fighting Carl Malamud to stop him putting their building code online. https://archive.org/stream/gov.ca.sf.electrical/ca_sf_electrical_djvu.txt https://archive.org/stream/gov.ca.sf.electrical/ca_sf_electr... (edited to fix 300mm to 600mm. I know 600mm isn't quite 24in but that's what the code says)
