Before You Build - Development Requirements

All development in the Seabrook floodplain requires a permit per Chapter 38 of the Seabrook Code of Ordinances (revised November 18, 2016). Development includes, but is not limited to, all new construction, filling, grading, and paving. Substantially damaged or improved structures, where the cost of repair (regardless of the cause of damage) or improvements to a structure equals or exceeds 50% of the building’s (Improvement only not land value) market value, also require building permits and elevation certificates and are held to the same standards as new construction. | Visit the Development Requirements Page
