Tips

Don't skip the permit application just because the fee is waived — a permit is still legally required to finish a basement in Gillette.
Budget for the electrical permit fee even though building/plumbing/mechanical fees are typically free for a basement finish — electrical is explicitly carved out and charged at the standard rate.
If your basement finish requires opening the floor for new drain lines, or adding a water heater or furnace, expect the normally-waived plumbing/mechanical fees to apply.
