About this data · Data quality: Strongest of the four

Sources

Taipei City Construction Management Office and New Taipei City Public Works Department: registers of building management organisations, and occupancy permit records with unit counts, floors and completion dates. Open Government Data License 1.0 (compatible with CC BY 4.0).
Taipei City and New Taipei City doorplate registers (3.1 million door and floor entries): locations and unit estimates.
OpenStreetMap (ODbL): building outlines, district boundaries and the basemap.

Quality

Names, addresses and registration come from the cities' own registers, which are authoritative.
About half the buildings have an exact unit count from their occupancy permit. Most of the rest are counts of registered doors and floors, which is accurate for small and mid-size buildings. It undercounts big complexes (300+ units), often by half, and counts shops with their own door.
96% are on the map, placed from the cities' own address points rather than a geocoder.
Almost no English building names exist. Districts and cities are in English and Chinese.

How complete is the data?

Complete for what it covers, but it covers only buildings that registered a management organisation. Taipei reports about 73% of eligible buildings had registered by March 2025; New Taipei publishes no rate. Missing are older walk-up buildings that never formed a committee, which are also the least likely to buy community software. Permit unit counts start in 2001–02, so older buildings rely on estimates.
