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 the converted space 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. Turning a garage into a bedroom, living room, office or apartment changes it to habitable space, which must meet the code for living areas, such as insulation, heating, ceiling height, light, and an emergency escape opening in any sleeping room. A conversion normally needs a building permit, and often electrical, mechanical and plumbing permits too. Zoning may also require you to keep off-street parking or limit a second unit, so check zoning before you design.
