how do i do this to meet electrical code?

Answers:    You want to attach some 12 AWG line to an existing 15 amp 14 AWG wire circuit? That is no problem as long as you move the overcurrent protection at 15 amps. And that is of late fine with the electric code.

Want to attach some 14 AWG chain to an existing 20 amp 12 AWG wire circuit? Nope. Use 12 or modification the overcurrent protection devise to 15 amps. Per the same electric code.

Yes, 14AGW is sufficent to transport 15 Amps of current.
