What are the permits and timeline for building on a vacant Keys lot?

Steve Conley | August 24, 2026

Short Answer

Building on a vacant Keys lot requires a ROGO allocation (2 to 10+ year wait depending on tier), environmental permits from multiple agencies, building permits from Monroe County, and compliance with FEMA elevation requirements. From securing an allocation to receiving a Certificate of Occupancy, the total timeline is typically 3 to 5 years.

With my contractor's license, I can tell you that building in the Keys is a long game. Even after you secure a ROGO allocation -- which can take years on its own -- you still need environmental permits from the DEP and Army Corps, plus a building permit from the county. I tell buyers to plan for 3 to 5 years from lot purchase to move-in. That timeline surprises most people, but it is the reality of building in a place with strict environmental protections and limited building allocations.
