2771 Monument Rd Jacksonville, FL gets marked as RESIDENTIAL but as soon as I add a suite number it
2771 Monument Rd Suite 19 Jacksonville, FL it gets marked as COMMERCIAL? How can the same location be marked as BOTH?
This is due to the way the USPS has the addresses indexed. It looks like the building default address is listed as residential but each specific unit is determined individually. Note that the response comes back saying it is missing secondary and "default" address, so that is an indicator for you.
Consider a high-rise building that has businesses on multiple floors but also has residents living there. The addresses for all of them will be the same but with different suite/apt numbers. So, the default address (or the base address) might be marked as RESIDENTIAL, while there are certainly commercial businesses within the building.
Seems kind of funny to list the whole thing as residential. I would think that mixed occupancy would be classified as commercial but it's their classification system. It doesn't have to make a lot of sense.
