Reasonable accommodation goes both ways. Even though National Electrical Code (NEC) 90.4 brings to mind alternative methods and how they ought to be documented, 90.4 is not just about authorities having jurisdiction (AHJs) accepting work-arounds. Consider the following installation. An old customer moved away from my normal working area and wanted me to take care of a few things in his new home. He was still within a reasonable drive, so I renewed my license in the jurisdiction. The major task was wiring a hot tub he had bought for his rear ground-floor deck, which was an existing concrete slab. The tub hadn't been delivered yet, but he thought it would be set about 5 feet from his house. This got me thinking. Inside the single-family residence, I could use any Chapter 3 wiring method for the tub. The same was true for wiring the required convenience receptacle. (There was no outdoor receptacle on that side of the house.) Outside the house, though, the tub wiring was more restricted. I had to run a suitable raceway from the house to the tub.
