Zillow Building Details API - Apartments and Amenities

Use building_key for either a documented alphanumeric Zillow building key or a latitude,longitude pair in the same path field. A building key identifies a multi-unit building and is not a property zpid. The documented response covers building name, address, amenities, attributes, scores and available units. Optional include accepts comma-separated photos, schools, comps, floor_plans, nearby, market or reviews. This route has no saved live response; its exact unit schema, optional attachments and availability were not verified. Do not treat a returned available-unit set as a complete building rent roll or assume that every unit can be leased. Keep building-level records separate from any individual property IDs.

API Features

Building-key resource identity Keep multi-unit building keys distinct from the numeric zpids used by individual-property endpoints.

Coordinate-form building input The documented path input also accepts a latitude,longitude pair instead of adding separate query fields.

Available-unit building context Research documented available units alongside building-level name, address, amenities and attributes.

Building-specific extension names Select optional floor_plans, comps, nearby, market and other documented building attachments rather than property-only include values.

Frequently asked questions

Is a building key the same as a zpid?

No. A building key identifies a building resource, while zpid identifies a property. Do not pass a property ID as a building key merely because it is available.

How are coordinates supplied to this route?

The documented building_key path value may be a latitude,longitude pair, such as 40.665474,-73.844894. This input form was documented but not live-verified.

Does the available-unit list represent the whole building?

No complete rent roll or leasing guarantee was verified. The route is documented to return available units, which can change and may not include every unit or attachment.
