BTO Waiting Times: How Long Every Recent Project Takes, and How to Track Construction

• Recent completions: "In 2025, HDB completed about 19,600 flats across 28 housing projects, with a median wait time of about four years" (HDB, 8 January 2026).
• Recent launches: HDB's estimates for the project launches from October 2025 to June 2026 run from 23 to 59 months. Counting each launch once, the median is 42 months; counting each flat once, it is 47, because the slower Prime launches were bigger on average (see the next two sections).
• What the clock measures: HDB's estimate "is computed from the median month of flat selection exercise of this sales launch to the median of the projected completion month of the blocks within this project" (HDB, Annex A). MND describes it as the time "successful applicants per project have to wait between flat selection and key collection, which is largely dependent on construction duration" (MND, January 2023).

The clock starts at flat selection, not at your application. In HDB's October 2025 exercise, applications closed on 22 October 2025 and booking was due to begin in March 2026 (HDB, Annex C), so add several months to the published figure.

Count from the day you apply, not the day you book: the real wait is the published one plus the queue.

Source: HDB's estimated waiting times in the Annex A price list of each launch (October 2025, February 2026, June 2026). HDB prints two figures for Berlayar Rise, 49/54; we count it at 49. Redhill Peaks was launched in two parts, in October 2025 and February 2026, so it appears twice.

HDB publishes each project's estimate on launch day, in the launch's Annex A, so the waits for the November 2026 projects will be known then: see our BTO launch schedule.

Within a single launch, the estimates differed by up to 32 months (February 2026): check the project, not the exercise.

• What MND says: factors include "site conditions and the height of the buildings", and projects "with difficult site conditions or with very high storey-heights will require more construction time" (MND, July 2022).
• A worked case: Redhill Peaks has 2,073 flats on two land parcels. The second "required more time for site preparation", so HDB launched it separately, in February 2026, "to avoid extending the waiting times for flat buyers" (HDB, 4 February 2026). The two parts were estimated at 53 and 55 months.
• The label is not the cause: Teban Heights, a Standard project, was estimated at 48 months, a month longer than Prime Bishan Terraces at 47.
• How HDB shortens waits: it works "in early planning to identify and prioritise project sites available earlier", so that "construction can commence even before the project is launched for sale"; by the time buyers book, "construction would be well underway" (HDB, 7 June 2026).

If you need a flat soon, read the estimate, not the label: every recent Prime launch was estimated at almost four years or more, and most Standard launches at under three.

Source: HDB's releases for each launch (15 October 2025, 31 January 2026, 17 June 2026); the shares are PropKaki's arithmetic. HDB's counts equal the flats in projects with an Annex A estimate under 36 months.

• Definition: "Shorter Waiting Time (SWT) flats with wait times of less than three years" (HDB, 8 January 2026), offered "since SWT flats were introduced in 2018" (HDB, 31 January 2026).
• 2026 target: "more than 4,000 flats (about one-fifth of the 2026 flat supply)" (HDB, 8 January 2026).
• Near misses: HDB also points buyers to projects just over the line: Kim Keat Crest in February 2026 and Kebun Baru Ridge in June 2026, each at 3 years and 1 month. HDB's June pre-launch count of "2,520 Build-To-Order (BTO) flats with wait times of around three years or less" includes Kebun Baru Ridge (HDB, 7 June 2026).

To see how many people applied in each town, including the towns with SWT projects, see our guide to BTO application rates.

SWT flats come in under three years, against a median of 42 months for recent launches, but only where HDB can start building early.

The rows are not strictly comparable: two are actual waits, two are HDB's estimates at launch, and HDB does not say how its 2025 figure is measured.

• Before the pandemic: "the actual waiting time for BTO projects was about 3 to 4 years" (MND, July 2022).
• The delays cleared: "HDB has completed all 92 pandemic-delayed housing projects, delivering over 75,800 new flats", and in January 2025 "there are currently no delayed projects among the projects under construction" (HDB, 20 January 2025).
• Scale in January 2026: "there are 127 HDB housing projects under construction, an increase from 110 a year ago" (HDB, 8 January 2026).

For recent launches the typical estimate is three and a half to four years from booking (42 months by project, 47 by flat), and under three for Shorter Waiting Time projects.

• HDB's tracker is MyHDB Page: "Check the building progress of your flat via MyHDB Page" (HDB, key collection). Log in to MyHDB Page with Singpass; your booked flat is under My Flat > Application Status > New Flat, which is also where you check or change your key collection appointment.
• Completion date: "You may view your flat's latest Probable Completion Date (PCD) on MyHDB Page." HDB: "The PCD is the estimated completion date of your flat. The actual completion date may vary depending on the construction progress."
• Blocks finish at different times: HDB completes the blocks in a project progressively, and a block that looks ready from outside may still have works in progress, such as doors, sanitary fittings, electrical installations and cleaning (HDB).
• Before booking: your application sits on My Flat Dashboard in the HDB Flat Portal, where HDB posts the ballot results within 2 months after the application period closes (HDB, application).

After booking, watch the Probable Completion Date on MyHDB Page rather than the launch estimate.

• The invitation: "You will be invited to collect the keys to your booked flat when the keys are ready", by email and SMS within 2 weeks before the appointment (HDB, key collection).
• The deadline: "you must take possession of the flat within 1 month from the date of HDB's notice"; deferring longer means you "will need to pay daily interest on the balance purchase price of the flat".
• What you pay: the balance of the price, the stamp and legal fees and any resale levy, which HDB requires "in full before key collection"; an HDB housing loan "will be issued on the key collection appointment".
• Moving in: "After key collection, you will become the flat owner" (HDB). Everyone listed "must physically reside in the flat within 6 months after key collection", and "any period of non-occupation during the 6 months will be excluded from the MOP computation" (HDB, Sign Agreement for Lease).
• Not collecting: "your flat application will be cancelled": you "forfeit the option fee and 5% of the purchase price" and must return any CPF housing grants paid out, "with accrued interest" (HDB, key collection).

Waiting for keys? Families with a booked flat may qualify for HDB's temporary rental flats: see our guide to the Parenthood Provisional Housing Scheme. For the payments at each stage, see how to apply for a BTO flat.

Collecting the keys makes you the owner, and any of the first 6 months you don't live there doesn't count toward your MOP.

Official figures. Estimated waiting times are HDB's, from the Annex A price lists of the October 2025, February 2026 and June 2026 launches; Shorter Waiting Time counts from HDB's releases of 15 October 2025, 31 January 2026 and 17 June 2026; the October 2025 timetable from that exercise's Annex C; the Redhill Peaks split from HDB's release of 4 February 2026; completions, projects under construction and the 2026 target from HDB's release of 8 January 2026; historical waits from MND's written answers of July 2022 and January 2023; pandemic delays from HDB's release of 20 January 2025; key collection from HDB's key collection page (updated 21 August 2026), the occupation rule from its Sign Agreement for Lease page (updated 18 August 2026) and ballot results from its application page (updated 17 August 2026). All read on 19 September 2026.

Our analysis. The medians, ranges and shares, and the grouping by classification, are PropKaki's arithmetic on HDB's figures. Each project launch counts once, so Redhill Peaks, launched in two parts, counts twice, and Berlayar Rise counts at its first figure, 49 months; counting each flat once instead gives a median of 47 months. How we work: PropKaki methodology.

What we have not claimed: when any flat will actually be completed, which HDB sets and updates in each buyer's Probable Completion Date; that the historical figures are like for like, since they mix actual and estimated waits; or that no current project is delayed, which HDB last stated in January 2025.
