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, Kansas City, the City of St. Louis, Springfield and St. Louis County, run full permit programs, and each sets its own fees.
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.
