Bishan is treated as a Singapore micro-area anchored to the URA Bishan planning area or subzone and the D20 postal district. For CASABROVA it functions as a residential investment comparison unit rather than a separate municipality: liquidity, tenure mix, public-transport access and HDB/private housing depth should be assessed inside the wider Rest of Central Region bucket. The seed keeps STR flagged as banned because normal residential accommodation cannot be let for tourist-style short stays.
