Tips

Fee is based on total building square footage under a simple tiered table — not a percentage-of-valuation model like many other cities.
Plan review is free for one- and two-family dwellings in Gillette — unlike commercial projects, which pay $100/$200/$1,125/$1,500 for the 1st/2nd/3rd/4th+ review.
Call the Inspection Line before 7:00 a.m. to get a same-day inspection; field inspectors are generally in the office 8–9 a.m. and 1–2 p.m.
A Foundation Location Certificate from a licensed Wyoming surveyor is required before any inspection beyond the foundation stage can proceed.
