What to check before buying property in Taiwan (self-check list)

Before buying, check at least six public datasets: (1) active faults, (2) soil liquefaction, (3) flood potential, (4) nearby nuisance facilities, (5) actual transaction prices and building age, (6) urban-renewal scope. All are Taiwan government open data.

Geology & hazards (most important)

Active faults, soil liquefaction and flood potential drive earthquake and flood risk. AI DD Map’s property map overlays the official active-fault layer; liquefaction/flood link to official systems.

Nearby nuisance facilities

Gas stations, temples, funeral facilities, substations and telecom masts affect livability and resale. The map scans within 500 m of your pinned point in real time.

Price & title

Check the actual-price registry for transaction prices and building age, and urban-renewal scope for redevelopment potential or risk.

FAQ

Does it flag “haunted houses” (deaths on site)?

No — that is sensitive personal/reputational data; this site builds no address-level database.

Does typing an address auto-locate it?

Free geocoding of Taiwan street addresses is often imprecise, so you pin the exact spot on the map.
