In most cases, you will not need a permit to construct a patio in Maryland. This includes any patios made from brick, block, pavers, stone, or concrete. Because patios are most often built at grade, or ground level, permits are not required. However, if you are planning to install a large patio that spans 500 square feet or more, you may need a permit due to the size of the project. Our team can help you through this process should you need one.
