Monroe County
Structural engineering in Islamorada.
Islamorada, the Village of Islands, runs through the Upper Keys across Plantation, Windley, and the Matecumbe Keys. As part of Monroe County it is outside the High-Velocity Hurricane Zone, though wind speeds are very high and nearly every parcel is in a special flood hazard area.
On these narrow islands, oceanfront and bayfront lots make flood elevation, V-zone construction, and enclosure limits central to the design. We prepare the sealed engineering an Islamorada permit calls for, with the flood basis read from each parcel's FIRM and survey and the wind design from the ASCE 7 hazard tool.

What we typically engineer here.
- Ground-up elevated homes and additions on narrow coastal lots
- Below-base-flood enclosure, deck, and dock engineering
- Wind design and opening protection per the wind region
- Foundation and tie-down engineering for coastal conditions
- Milestone (recertification) inspections for qualifying buildings
Not HVHZ, but very high wind
Islamorada follows the Florida Product Approval (FL#) regime rather than the Miami-Dade NOA regime, with wind-borne-debris opening protection still required for the wind region. The parcel's design wind speed comes from the ASCE 7 hazard tool per project.
Flood governs the design
Nearly all Islamorada parcels are in special flood hazard areas, with VE common oceanside and AE on the bay side. Elevated construction, below-base-flood enclosure limits, and V-zone requirements frequently drive the structure. Zone, BFE, and datum are confirmed from the parcel's FIRM and survey.
Permit timing (ROGO)
The Keys' Rate of Growth Ordinance (ROGO) can affect permit timing for new units. It is a permitting-schedule matter rather than an engineering one, but worth planning around early.
Recertification
Florida's statewide milestone inspection (FS 553.899), called a recertification inspection locally, applies to condominium and cooperative buildings three or more stories, first at 25 years, then every 10. We handle the structural inspection and sealed report.
Code & design basis
What governs work in Islamorada.
Jurisdiction-level facts below are confirmed against primary sources. Parcel-specific values such as exact wind speed, flood zone, and zoning are confirmed per project for your address.
- HVHZ
- No, Monroe is not in the HVHZ
- Product approvals
- Florida Product Approval (FL#) regime; opening protection per wind region
- Wind design
- Very high wind region (180+ mph class); the parcel value is confirmed from the ASCE 7 hazard tool per project.
- Flood
- Most parcels are in special flood hazard areas (A/AE/VE); zone, BFE, and datum confirmed per project.
- Permit timing
- ROGO allocations can affect scheduling, a permitting matter, not engineering.
- Recertification
- The statewide milestone inspection (FS 553.899) applies, called a recertification inspection locally: 25 years for coastal condo/co-op, then every 10.
- Code
- Florida Building Code 2023 (8th Edition); ASCE 7-22 wind provisions.

Common questions
Islamorada, FAQ
Is Islamorada in the HVHZ?
No. Monroe County, including the Village of Islamorada, is outside the High-Velocity Hurricane Zone. Opening protection is still required for the wind-borne-debris region under ASCE 7, using Florida Product Approval products rather than the Miami-Dade NOA regime.
Why is flood such a big part of an Islamorada permit?
The islands are narrow and low, so nearly all parcels are in AE or VE flood zones. Base flood elevation, V-zone construction, and limits on enclosures below the flood elevation frequently govern the foundation and structure, read from your FIRM and survey.
Do I still need opening protection if it is not HVHZ?
Yes. Wind-borne-debris opening protection is still required for the region under ASCE 7, using Florida Product Approval (FL#) products rather than the Miami-Dade NOA regime. We confirm what applies to your parcel.
