Limited regulatory reach, one threshold to watch
Cladding replacement falls mostly outside floodplain and stormwater administration. The exception is scale: on a property inside a mapped flood zone, work extensive enough relative to the structure's value can engage improvement requirements. Otherwise the consequential factors are physical — what the water-resistive barrier behind the cladding is doing, and how wind-driven rain reaches exposed elevations.
Official sources
Confirm the parcel, then confirm what is behind the cladding
Citywide records cannot tell you your parcel's flood status, the condition of the barrier behind your siding, or whether sheathing beneath it is sound. Check the first with LFUCG if the project is substantial, and the rest at tear-off.
