Is there any code requirements determining how close a ceiling fan can be to a pendant light?
Roundabout &quot;code&quot; reference.
Several fan makers specify 39 inches (remarkably/suspiciously close to 1 meter) as minimum clearance from fan-blade-tip to pendant-light-chain.
Code requires that you follow the maker's instructions.
So, if the maker of your fan has language like that, which may or may not have the same measurement, you should follow the instructions of the maker of your fan.
If not, you're back to what common sense will insist on teaching you.
