TIL the local code in Springfield allows aluminum wiring in new residential builds

I rewired a 1950s house there last month and found the original aluminum branch circuits. Everyone at the supply house said to rip it all out, but after checking the 2023 NEC and the city's amendments, it's still listed as acceptable for new 15 and 20 amp circuits with the proper connectors. I kept the existing runs where they were in good shape and just updated the devices. Has anyone else worked under a jurisdiction that still permits this?

You're right that the code still allows it, but that doesn't mean it's a good idea. I've seen too many melted outlets and scorched wires in old aluminum jobs. Even with the right connectors, the metal expands and contracts differently than copper. If you're keeping the old runs, you better be damn sure every single device is rated for aluminum and you used the antioxidant paste. One loose connection is all it takes.

Honestly, nobody's talking about how aluminum's price swings could make it the only option for affordable housing soon.
