Do I need a permit to repair a seawall in Gulf Stream?

Yescommission approval + building permit

Yes. Gulf Stream's Town Commission approves all construction plans for seawalls, and every applicable regulatory agency must approve in writing first. Building permits are issued by Highland Beach under an interlocal agreement, after Gulf Stream's zoning sign-off, and the code requires Intracoastal-fronting owners to keep their seawalls structurally maintained.
