Do I need a permit for kitchen remodel in Chesterfield?
It depends. Whether kitchen remodel needs a permit in Chesterfield comes down to the details of your project.
Missouri has no statewide residential building code; whether a permit is required depends entirely on the city or county code that covers the address. Do not assume the model IRC R105.2 list of work exempt from permit applies; the state has not adopted it, so each local code sets its own exemptions. 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. Under RSMo 67.309, a city or county may not bar connection of a utility service such as natural gas, propane, or electricity based on the type of energy. This remodel moves walls, plumbing or gas lines, or adds electrical circuits. Replacing cabinets, counters and appliances in place is the part of a kitchen remodel most often exempt; layout and trade work are not. Each trade normally needs its own permit and rough-in inspection before walls are closed, and removing a load bearing wall usually needs a beam detail or engineering. Gas line changes are work many places restrict to licensed gas fitters or plumbers, and a pressure test is commonly part of the inspection.
