Singapore HDB at a Glance

Numbers that frame the scale of public housing in Singapore and why renovation rules matter.

80%+
of Singaporeans live in HDB flats

The Housing & Development Board manages over one million residential units across the island, making its renovation guidelines among the most widely applicable in the country.

5 yrs
Minimum Occupation Period for new BTO flats

BTO flat buyers must fulfil a 5-year MOP before selling or subletting. Renovation work during this period is subject to additional checks by HDB officers.

3 months
Typical permit processing window

Most renovation permit applications take between 1 and 3 months to process. Structural works involving RC walls or beams may require longer review cycles and PE-stamped drawings.

$5,000
Maximum fine for unauthorised works

Carrying out renovation without a valid permit from HDB can result in fines and a mandatory reinstatement order — meaning walls or fittings must be returned to their original condition at the owner's cost.
