About ADUs & Guest Houses in Flagler Beach
Flagler Beach ADUs face unique coastal construction challenges — flood zone compliance, salt-resistant materials, and wind engineering. Wilson & Co builds coastal ADUs designed to perform in Flagler Beach's demanding environment while meeting all FEMA and local code requirements. The result is a durable, comfortable living space that adds rental potential or family flexibility to your coastal property.
Many Flagler Beach properties in flood zones require elevated construction for new structures. An elevated ADU can actually be an advantage — providing covered parking or storage underneath while living space sits above BFE (Base Flood Elevation). We design for these requirements from the start.
