#12 and #14 in same conduit?

Im running a 20A circuit for laundry. 2x12
I like to use the same 1/2" emt to run 2x14 for a 15A lighting circuit.

Is it bad practice to mix the gauges in the same conduit?

Is the laundry in the same structure as the panel supplying it?

You can mix conductor sizes in the same conduit. An EGC, if run, needs to be sized for the largest circuit.

Yes laundry is in basement and lighting circuit is also in basement both supplied from same panel.

Is mixing the two atypical? Would this be considered sloppy work or wouldn't pass the inspection?

No code issues as long a conduit fill rules are observed.

Mixing wire sizes is done all the time. You should group the wires of each circuit (hot/neutral, hot/hot, ect.) together with tape at each junction box.
