Zoning and the Rate of Growth Ordinance (ROGO) in Monroe County, Florida

Why the Keys have a permit-allocation system at all

The Florida Keys are a narrow chain of islands connected to the mainland by a single highway, US 1, which creates a hard physical ceiling on how quickly the resident and visitor population can evacuate ahead of an approaching hurricane. Florida designated the Keys an Area of Critical State Concern in the 1970s largely because of this evacuation constraint combined with the islands' environmental sensitivity, and by the early 1990s Monroe County had adopted the Rate of Growth Ordinance (ROGO) specifically to keep residential growth within the limits that hurricane evacuation modeling suggests the islands can safely handle. This isn't an ordinary zoning density limit -- it's a growth-management tool built around a life-safety constraint, and it operates on top of, not instead of, the county's underlying zoning code.

Practically, this means Monroe County issues only a limited number of new residential building permits in the unincorporated Keys each year, allocated through a competitive scoring process rather than granted automatically to every property owner who applies. The system has been the subject of legal challenges and periodic adjustment over the decades since its adoption, reflecting ongoing tension between private property rights and the county's hurricane-safety and environmental rationale for limiting growth -- worth keeping in mind as context, even though this page doesn't attempt to characterize the current status of any specific dispute.

How the allocation and scoring process generally works

Under ROGO, property owners seeking to build a new residential unit in the unincorporated Keys generally submit an application that is scored against a set of criteria set out in the county's land development regulations -- factors that have historically included the environmental sensitivity of the site (proximity to wetlands or sensitive habitat scores unfavorably), whether the lot is a legally platted lot versus one created more recently, and other land-use considerations tied to the comprehensive plan. Applications are then ranked, and permits are awarded from the year's limited allocation pool in score order until the pool is exhausted, with unsuccessful applicants generally able to reapply in a subsequent allocation period.

A meaningful number of vacant, legally platted lots across the unincorporated Keys predate ROGO and current environmental standards, and some may face a long wait -- or persistent difficulty -- competing successfully for a permit allocation given how they score under current criteria. This is the single most important due-diligence question for vacant Keys land: not simply "is this lot zoned for a house," but "how does this specific lot's environmental and locational profile score under the county's current ROGO criteria, and what does that suggest about realistic timing."

1. Before buying vacant Keys land with development plans, ask Monroe County's Planning & Environmental Resources Department directly for a current ROGO scoring assessment or guidance specific to the parcel.
2. Confirm whether the lot is a legally established, buildable lot of record, since older platted lots can face specific eligibility questions under current standards.
3. Ask about the size and competitiveness of the current year's allocation pool relative to pending applications in the parcel's area, to get a realistic sense of timing.
4. Understand that ROGO operates in addition to, not instead of, ordinary zoning compliance -- a parcel can be zoned appropriately and still not receive a permit allocation in a given cycle.
