Tier 3 ROGO Lots Skip the Permit Wait

Tier 3 ROGO-exempt lots are the rare workaround that let owners skip the wait entirely. Here’s the quick guide:

1. What is ROGO + Tier 3?

• ROGO = Rate of Growth Ordinance. Monroe County limits how many new residential building permits are issued each year to control growth and protect the Keys environment. Most vacant land sits in a queue for years waiting for allocation points.

• Tier System: The county ranks land 1-3. Tier 3 is the least environmentally sensitive, so it’s the most likely to be developable — but you still need ROGO points unless you’re exempt.

2. What makes a lot “ROGO-exempt”?

A lot gets a ROGO exemption letter when it’s already entitled to build without pulling from the annual allocation. Common ways this happens:

• Grandfathered rights: Lot had a home previously, or was legally buildable before ROGO in 1992. If there was a structure — even a trailer — the right often carries over.

• Merged parcels with exemption: Two adjacent parcels combined under one folio can secure an exemption that applies to the new larger lot.

• Existing ROGO allocation: The lot was already awarded points in a past ROGO year and they haven’t expired.

• County letter in hand: True exempt lots come with documentation from Monroe County saying “you can pull a building permit now.” Realtors call this “ROGO-exempt letter in hand.” 

3. How they bypass the permit queue

Normal process: Buy land → Apply for ROGO → Wait for points to be issued, which can take years → Then apply for building permit.
Exempt process: Buy land → Skip ROGO wait because exemption letter = you already have the right → Submit plans straight to building department for review. You still need standard permits like FEMA, elevation, septic, and zoning, but you don’t sit in the ROGO line. 

4. Why Lower Keys Tier 3 canal-front sites matter

• Canal access + Tier 3: Many Tier 3 lots in Big Pine Key, Cudjoe, Ramrod have 60-70ft seawalls, boat lifts, and direct ocean access.

• Inventory is tiny: ROGO-exempt canal parcels are “one of the hardest combinations to find”. When they hit the market, agents push “build now, not someday”.

• Existing structures help: Lots with a mobile home, cottage, or even demo permit already started often clear ROGO faster because the use was established. 

5. What to check before you buy

1. Get the exemption letter - Don’t take the listing’s word. Have your attorney or title company verify the ROGO-exempt status with Monroe County Growth Management.

2. Confirm buildable SF + setbacks - Exempt doesn’t mean unlimited. 6,000 SF lots are common, but FEMA + setbacks shrink what you can build.

3. Utilities + elevation - Canal lots still need to meet base flood elevation. Check if sewer is available vs septic.

4. Dock rights - Many exempt listings highlight “private dock” or “10,000 lb lift”. Verify riparian rights transfer.

5. Demo permits - If there’s a teardown structure, an approved demo permit adds value and keeps ROGO rights intact.

6. The catch

• Price premium: Exempt lots list higher because you’re buying time. Recent Key Largo 18,100 SF exempt double lot was $795k.

• Still need other permits: You skip ROGO, not building code. Army Corps for seawall, DEP, HARC if historic, etc. still apply.

• Exemption can be lost: If you re-subdivide or let rights lapse, you’re back in the queue.
