Oregon law on a lot: Accessory dwellings (ORS 197.312).
An Oregon lot sheet on ParcelSheet shows the FEMA flood zone, wetlands, wildfire hazard, faults, septic soil rating, slope and 3 ft sea level rise for any address, each with its public source, and points to the zoning office. Lot lines show where the county shares a public parcel map; elsewhere a spot opens every card. Free to start.
