If your home is below the base flood elevation, you will only be allowed to do renovations that are worth up to 50% of its depreciated value. And every municipality has its own rules on how long you must wait before doing additional improvements. If you plan to use construction tools to install a new roof, replace your flooring, as well to redo your kitchen and bathroom (which is all worth 49% of your home’s value), some areas will make you wait 1-5 years before you can do any more upgrades. If you plan to build a home that’s located below the BFE, you will have to make sure it’s raised above the floodplain. It’s important to work with an engineer and contractor who understand all the FEMA guidelines and building codes, so they can use drafting supplies to make sure your home is built according to their standards.
