How permits work in Missouri
Missouri has no statewide building code, no statewide energy code, and no state permit office. Adoption is purely local, and the official state data portal shows what that produces: dozens of counties with no residential code at all, next to counties running codes a decade apart in vintage (Boone County on the 2015 IRC while Cass County still cites 2006 editions). Identical projects can be permit-free on one side of a county line and fully inspected on the other.
All four Missouri jurisdictions we track run real programs, and the spread between them is the widest in-state ratio in our index. A bathroom remodel permit costs $114.29 in Kansas City, the cheapest in our 29 cities, against $380 in the City of St. Louis, $421 in Springfield, and $431 in St. Louis County. Nearly a 4x difference inside one state.
Lawmakers keep proposing a statewide code (a Missouri Building Codes bill appeared in the 2024 House session and again in the 2025 Senate), but as of mid-2026 nothing has passed. Until that changes, the only question that matters is hyper-local: what has YOUR city or county adopted, and in what year? The state's energy office keeps the official jurisdiction-by-jurisdiction list.
