Canal Homes Along the Bayside and Oceanside of US-1
Key Largo's housing stock is dominated by canal front single family homes on both the bayside and oceanside of US-1, many built up on pilings or elevated slab to meet Monroe County flood requirements. Roof area is generally generous and unshaded, which makes sizing straightforward once we account for canal setback and dock equipment that sometimes competes for panel space near the water.

Permitting and construction
What Monroe County Permitting Means for Key Largo Solar
Upper Keys Monroe County Review
Key Largo permits route through Monroe County's Upper Keys office, with review timelines and product approval requirements consistent across the Keys.
Flood Zone and Elevation Requirements
Nearly every Key Largo parcel carries flood zone documentation requirements, and we mount inverters and battery equipment above base flood elevation as standard practice.
Corrosion Protection
Key Largo sits between the Atlantic and Florida Bay, so every mount uses stainless hardware and marine grade sealant as a standard, not an upgrade.
Shipping logistics
Why We Batch Key Largo and Upper Keys Projects Together
The Overseas Highway is a single road in and out, and that shapes how we stage a project.
| Logistics factor | Mainland Miami-Dade job | Key Largo job |
|---|---|---|
| Material staging | Staged at the job site day-of | Consolidated in Miami, trucked down US-1 in one run |
| Missed part or reorder | Same-day resupply | Multi-hour round trip, so we over-order slightly on hardware |
| Crew scheduling | Split across nearby jobs same week | Multiple Key Largo and Islamorada jobs scheduled in the same trip |
