    • Post-Maria reconstruction at scale

      Puerto Rico is still rebuilding from Hurricane Maria, and much of the affected stock was informally built without permits or inspection, leaving no baseline to rebuild against.

    • Aging pre-code housing stock

      A large share of Puerto Rico's homes predate modern code enforcement, with unreinforced additions and roof connections that concrete-block construction alone does not solve.

    • Continuous tropical humidity

      With no dry season to speak of, Puerto Rico interiors hold moisture year-round, and mold returns quickly after any storm-related wetting.

    What Climate Zone 1A Means for Puerto Rico Homes

    Puerto Rico is a Zone 1A tropical archipelago of roughly 3.2 million residents, the largest housing market in the US territories. Hurricane Maria exposed how much of that stock was built informally, before or outside code enforcement, and reconstruction is still shaping how homes are built. Add active seismic faulting off the southwest coast and a grid that fails under load, and resilience is a household-level question here.

    • Puerto Rico Building Code (IBC/IRC based with hurricane and seismic provisions)

      The territory's code carries elevated wind-speed requirements and seismic design provisions reflecting the Puerto Rico Trench fault system.
