No it is not a violation. High rise condos are usually constructed of poured in place concrete and full of conduit (usually smurf tube) in the walls and decks. The deck heights in condo?s and hotels are very low not leaving much room for conduits in the ceilings.

Re: Conduit in concrete

watch for low-voltage & communications cables in core line [cast-in-place] installations also. it is important in high-rises and other slab-floor installations to verify that the concrete you are about to core or hammer-drill through does not contain cable. unfortunately once a communications cable is severed in a core line it is often necessary to abandon the cable run and install a new cable, or to enlarge the hole significantly to install a functional splice point. unlike conduit, core line is notoriously difficult to pull through a second time, since it often contains more bends than a similar conduit path. we have had 200-pair telco cable, fiber-optic cable, and other wiring damaged by other trades thusly. never assume that a piece of concrete slab is unencumbered by hidden wiring.
