- There is no owner name in the file. You need another source for that.
- One inspection can have many violation rows, so the same address can repeat.
- Choose VIOLATION STATUS, not VIOLATION STATUS DATE. They sit next to each other in the list.
- The city says this data is historical and should not be relied on for closings.
