NYC Landmarks
A Claude Code skill that checks if a NYC building is individually landmarked or within a historic district using the LPC Individual Landmark & Historic District Building Database and PLUTO data.
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 queries PLUTO for address resolution and the LPC Building Database for designation details — including LP number, architect, style, and designation date. If the property is designated, it notes that exterior alterations require an LPC Certificate of Appropriateness before a DOB permit can be filed.
