What building in St. Augustine actually involves
- The ground
- Coquina, shell and centuries of fill — archaeological review can be triggered by excavation before a footing is ever poured.
- The water
- Matanzas Bay tidal flooding reaches downtown streets on king tides, which sets the floor elevation conversation for any renovation.
- The building stock
- Some of the oldest building stock in the country alongside 1920s frame houses, all of it visually regulated.
- The rules
- Permits run through City of St. Augustine, with Historic Architectural Review Board approval, and the Historic Architectural Review Board reviews exterior materials, windows, roofing and massing — approval comes before permitting, not after.
