Short Answer
ROGO (Rate of Growth Ordinance) is a Monroe County regulation that limits new residential development to control population growth, maintain safe hurricane evacuation clearance times under the 24-hour evacuation model, and protect local natural resources. It operates through a competitive points-based allocation system, with a small number of permits issued quarterly. If you are buying land, the most critical question is whether the lot has an existing building right (is ROGO-exempt) or will require competing in the allocation queue, where wait times can stretch for years depending on the tier classification.
What is ROGO and Why Does It Exist?
ROGO stands for the Rate of Growth Ordinance, a Monroe County regulation enacted to limit new real estate development and population growth in the Florida Keys. The ordinance was created to keep safe hurricane evacuation clearance times based on a 24-hour evacuation model, and to protect local natural resources including the fragile marine ecosystem, wetlands, and endangered species habitat that make the Keys unique.
How the ROGO Allocation Process Works
Monroe County issues a small number of new residential building permits each quarter based on competitive point totals. Applicants earn points across several categories, and permits are awarded to the highest-scoring applications. The system is designed to ensure that development happens in the most appropriate locations with the least environmental impact.
The Tier System
Land in Monroe County is classified into tiers that determine how viable it is for development:
- Tier I - Environmentally sensitive areas, endangered species habitat, and native vegetation corridors. These are very difficult or impossible to develop and earn zero ROGO points.
- Tier II / IIIA - Transition or special protection areas with added building restrictions. Development is possible but requires mitigation and additional permitting.
- Tier III - Disturbed or infill areas with existing infrastructure. This is the most viable category for building. Lots here typically need a baseline point score to qualify for an allocation.
Key Factors Every Buyer Must Understand
Not All Land Is Buildable. Many lots you will see listed are unbuildable conservation parcels, mangrove wetlands, or habitat buffers. A low asking price often reflects this reality, not a hidden bargain.
ROGO-Exempt vs. Active Allocations. A ROGO-exempt lot - often a property where a legal structure was previously destroyed by a storm or natural disaster - retains a permanent right to rebuild without entering the competitive queue. This is extremely valuable. For lots without this exemption, you must either compete for a scarce allocation or purchase a transferable building right from another property owner.
The Waiting List and Points Game. The standard allocation queue can take years. Passive perseverance points accumulate the longer you wait, and owners can boost their scores through land donation or environmental contributions. Savvy buyers factor this timeline into their plans from day one.
Strict Environmental Rules. Clearing native vegetation, disturbing mangroves, or building in velocity flood zones without proper permits results in severe fines from multiple agencies. The Florida Department of Environmental Protection, the Army Corps of Engineers, and Monroe County all have jurisdiction, and none of them are lenient.
Real-World Tips from the Keys
Do not rely on online listings or tax records alone to tell you whether a lot is buildable. Order a full parcel research report from Monroe County and have a local contractor or engineer walk the site. The difference between a $200,000 lot that is truly buildable and a $200,000 lot that is a conservation mangrove buffer is the difference between a home site and a very expensive nature preserve.
Steve's Advice

After 30-plus years in the Keys - with a contractor's license and home inspector license in my pocket - I can tell you the single biggest ROGO mistake I watch buyers make is assuming every vacant lot is buildable. I have walked people onto lots that looked perfect: beautiful trees, water views, quiet street. Then we pulled the Monroe County parcel record and discovered the lot was a conservation easement with zero ROGO points - effectively unbuildable. My advice is simple: before you write an offer on any piece of raw land, call Monroe County's building department with the parcel ID and ask three questions - what tier is it classified as, does it have any existing or transferable building rights, and is any portion of it mapped as conservation or native habitat. That three-minute phone call has saved my clients years of heartache and tens of thousands in due diligence. With my contractor background, I also look at the ground itself: mangroves, wetland flags, and vegetation lines that signal permitting problems. If the lot has invasive Brazilian pepper you can clear it. If it has native mangroves, those roots are off limits. Read the dirt before you buy the dirt.
