My home has a half-hot outlet connected to a dimmer switch. I have two questions about it.
First, is this a code violation?
Second, What would be better in the long term:
- Change to a standard switch
- Replace the outlet with a normal duplex outlet
- Other

Some things have a dim view of being dimmed
Things other than lamps, such as motors and some electronic loads, often take a rather dim view of being connected to a dimmed receptacle. This may range from merely "not working" to "overheating and catching on fire", something you (and the NFPA) would rather not have happen. So, the 2014 NEC prohibits your current configuration in 406.15:
This leaves you with two options -- either you can swap the culprit dimmer out for a switch, or you can use a special receptacle and plug to prevent non-lamps from being plugged in to the dimmed outlet.
Going Dimmerless
Swapping a dimmer for a switch is a relatively easy task, at least as far as single pole configurations are concerned:
Keeping pesky non-lamps at bay
Lutron makes a plug and receptacle combination for this job -- the receptacle you need is a Lutron HDTR, and you'll have to put the matching plug on whatever lamp you plug into the dimmed receptacle, as well.
This is the costlier and slightly trickier option of the two, but may be needed if the dimmer serves other lights as well as the half-dimmed receptacle or otherwise can't be removed.
