Vintage N.Y. Tenement House Dept. (BADGE)

Here is a Vintage New York City Badge, I think from around the 20's or 30's, but not sure. The badge reads TENEMENT HOUSE DEPT. N.Y. with the #230 at the bottom. The back of the badge still has the screw and shows nice age. 2-1/2" x 1-3/4".
If anyone knows about this type badge please let me know.
