In Lake Charles, the city's Permit Center issues building permits and reviews plans for new construction and changes to existing buildings, and you can call them at 337-491-1294 with permit questions about your property. Whether your floor needs a permit depends on the job, so we check with the city or parish office that covers your address before we start, and when one's needed, we handle the paperwork or walk you through it. Before the city issues a building permit, the plans have to include a foundation plan showing the footings, vapor barrier, fill and slab steel. For an enclosed home or business, or a substantial improvement to one, the city also sets a minimum floor height of one foot above the highest of four flood measurements, and that can decide how much fill goes under your floor. Calcasieu Parish strongly recommends soil testing by a geotechnical engineer and a foundation designed by a structural engineer or architect, because of how south Louisiana soils settle.
We're based in Lake Charles and pour floors across Southwest Louisiana, out to Moss Bluff and Sulphur and over the line into Orange, TX, and if your city isn't listed on the site, ask us. A lot of the ground we dig into around here is soft and holds water, so it's common to find more digging and fill under a floor than the homeowner expected.
