The building will still convert from finished foundation to finished building, even while paused. After it has converted, cancel all the light jobs, then unpause the game again and you won't be charged.
Oh hrm, I always wait for the foundation to fill in; I was too scared to do the cancel while it's still a solid block of green. I'll give it a shot tonight
TBH I never minded having the lights in storage since they'll be used eventually, but now I'm curious.
