Little regulatory reach, one exception

Window replacement sits largely 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 thresholds. Otherwise the consequential local factors are physical — hillside elevations take wind-driven rain, and installation detailing matters more than the glazing package specified.

Confirm the parcel, then confirm the openings

Citywide records cannot tell you your parcel's flood status, whether your openings are standard sizes, or the condition of framing behind them. Check the first with the city if the project is substantial, and the rest with whoever measures.
