/nyc-landmarks

What it does

Provide an address, BBL, or BIN and find out if the property is individually landmarked, in a historic district, or not designated. The skill resolves the property through PLUTO and queries LPC landmark data and designation reports for designation details — including designation status, name, date, and links to the original reports. If the property is designated, it notes that exterior alterations require an LPC Certificate of Appropriateness before a DOB permit can be filed.
