Can an HDB shophouse be sold separately as commercial and residential units

HDB classifies shophouses with attached residential quarters as commercial properties overall, but the living quarters are treated as residential for taxes like ABSD (only on the apportioned residential value) and property tax, while the shop portion is commercial. Purchases must be for the whole property by sole buyers (individuals over 21 or private companies), with no subdivision implied in standard transactions. For shophouses in general (including HDB types), they can only be sold separately if the titles are already divided; a single title means the entire unit must be sold together. Check the specific property's title status and zoning via HDB or URA records, or consult EdgeProp Singapore for transaction details on such properties.
