We monitor HDB, URA, MOM, ICA, BCA and IRAS daily. Every confirmed change to a rule this site relies on is listed here with a link to the official source. Rules in the tracker also show their own last-verified date.
Every statutory figure on this site was re-verified against official HDB, URA, MOM, ICA and IRAS sources. An automated watcher now monitors these bodies daily; confirmed changes appear here with their official source.
Official source: hdb.gov.sgThis changelog is generated from verified official sources only. It is guidance, not legal advice — always confirm with the relevant authority before acting.
