Understanding HDB
Renewal Programmes
The Neighbourhood Renewal Programme and the Home Improvement Programme have reshaped thousands of HDB blocks across Singapore since the early 1990s. This archive covers what each scheme entails, how decisions are reached, and what residents typically encounter along the way.
Key Programmes
Two distinct upgrading tracks
NRP and HIP address different scales of improvement — one focuses on shared estate spaces, the other on changes within individual flats.
Neighbourhood Renewal Programme
Covers communal and precinct-level enhancements: sheltered linkways, fitness corners, landscaping upgrades, and barrier-free access routes across multi-block precincts.
Read full overview →Home Improvement Programme
Addresses ageing infrastructure inside individual flats — spalling concrete repairs, pipe replacements, toilet upgrading, and optional add-on works funded partly by residents.
Read full overview →Balloting and Application Process
Neither NRP nor HIP follows a conventional application form. Instead, HDB selects eligible blocks and conducts precinct ballots. This piece explains how the selection and voting process works in practice.

Why upgrading matters in ageing HDB estates
Singapore's oldest HDB blocks were built in the 1960s and 1970s. Decades of heavy usage leave visible marks: concrete spalling, narrow corridors, lift-free blocks, and dated plumbing. The NRP and HIP were introduced to address these systematically, without displacing residents.
- Works are coordinated at the precinct level to minimise disruption across the neighbourhood
- Essential repairs under HIP are fully funded by the government for eligible flat types
- Residents retain a vote in the decision — blocks where fewer than 75% endorse HIP do not proceed
- NRP improvements remain after completion and are maintained by Town Councils
- Both schemes apply exclusively to HDB-administered public housing stock

Who is eligible?
HIP applies to flats in blocks built up to 1986 that have not previously undergone a Main Upgrading Programme. NRP eligibility is determined by HDB on a town-by-town basis, typically in consultation with the relevant Member of Parliament.
Flat owners receive written notification from HDB when their block is scheduled for selection.

How the Ballot and Selection Process Works for HDB Upgrading
Residents do not apply directly — HDB initiates the process. Here is how block selection, resident consultation, and balloting unfolds.
