You can sometimes build on or next to wetlands. You cannot legally fill a jurisdictional wetland just because you hold the deed. The Clean Water Act Section 404 program, state 401, and often a state coastal or environmental resource permit sit on top of ownership.
The first question is not “can I fill.” It is “is this a wetland, and is it jurisdictional?” That is a delineation, not a glance at Google.
Florida, Alabama, Mississippi
Florida’s ERP / state wetland path is its own project even when the Corps is involved. Alabama and Mississippi still run 401 and coastal consistency. Local floodplain and setback rules stack on all three. This page is not a substitute for a site opinion.
When it is possible
Avoidance and a smaller pad. An NWP if you fit. An individual permit plus mitigation if you do not. Pile-supported structures sometimes avoid fill they would have needed as a pad — sometimes.
Cypress Environment & Infrastructure delineates first, then tells you the honest permit path.
