Missouri has no statewide residential building code; whether a permit is required depends entirely on the city or county code that covers the address. Many rural Missouri counties have not adopted a county building code, and a county code applies only outside city limits; inside a city, the city's own code governs. Energy code requirements for insulating basement walls come only from a code the city or county has adopted; the Department of Natural Resources lists adopted codes by jurisdiction and says to confirm with the local jurisdiction. In cities of 15,000 or more, RSMo 341.060 directs the city to require a permit for plumbing work, so adding or moving fixtures will usually need one there. This basement project adds a bedroom, a bathroom or wet bar, or new electrical circuits, or moves the furnace or water heater. Finishing work of this kind normally needs a building permit and the matching trade permits. A basement bedroom needs an emergency escape and rescue opening, such as an egress window or door, which is one of the most common reasons basement work fails inspection. Plan for framing, electrical and plumbing rough-in inspections before insulation and drywall go up.
