The EIP/SPR restriction applies block-by-block and neighborhood-by- neighborhood , not to one universal block. A specific HDB block is “under restriction” only when its ethnic or SPR quota for the relevant buyer category has been reached, so you have to check the live eligibility for that exact block.

What that means

  • EIP caps how many flats in a block or neighborhood can be occupied by each ethnic group.
  • SPR quota also applies to resale eligibility for Singapore Permanent Residents, with limits checked at the block and neighborhood level.
  • If a quota is full, buyers in that category cannot buy in that block even if the price is acceptable.

How to verify it

The official way is to use HDB’s eligibility checker for the specific block you’re looking at.

TL;DR: there isn’t one single “currently restricted block”; it depends on the exact block and the buyer’s ethnicity or SPR status, and the live HDB check is the authoritative source.
