BTO renovation budget planner (2026)

KeyKaki does not publish an average BTO renovation cost. 0 of 190 renovation firms on our list show own-site prices (vendor dataset, checked 21 Oct 2026), and a consented quote index is not started. Use written quotes from firms you shortlist — not scraped averages from other sites.

How much does BTO renovation cost on KeyKaki’s data?

There is no KeyKaki average, median, or dollar-per-square-foot figure to show:

  1. 0 of 190 renovation firms have a non-empty own-site prices field (vendor dataset, checked 21 Oct 2026).
  2. A renovation cost index from consented anonymised quotes is not available yet.
  3. We will not invent package prices to fill that gap.

HDB permit and admin fees. HDB’s Application for a Renovation Permit page (checked 4 Nov 2026) does not state a renovation permit fee amount. It notes an administrative fee if unauthorised work is later allowed to be retained (amount not stated), and buying a copy of the floor plan at $5.

How to compare quotes without a fake average

Compare your own written quotes side by side — kitchen, bathrooms, carpentry, hacking or demolition, electrical, and other line items. Check each firm against public registries before you pay a deposit:

Those are facts from the registries, not a KeyKaki score. See CaseTrust and HDB Directory of Renovation Contractors and CaseTrust protections explained.

How long does BTO renovation take?

KeyKaki has no measured renovation-duration dataset yet. Timeline drivers you can plan without inventing averages:

  1. Your key-collection date
  2. The defect-report window (Defect check after keys)
  3. Permit and wet-area rules (HDB renovation permits and rules)
  4. Contractor lead time
  5. Progressive payment milestones (CaseTrust protections explained if accredited)
  6. Post-renovation clean and movers (Move-in sequence)

Questions

Why won’t you show an average cost or dollars per square foot?

KeyKaki has no sourced cost corpus. 0 of 190 renovation firms show own-site prices, and a consented cost index is not started. Other sites’ averages are not our data.

How should I compare quotes then?

Line up written quotes item by item, then check each firm’s ACRA, HDB Directory of Renovation Contractors, and CaseTrust status on the official lists. KeyKaki lists 186 firms with an HDB directory reference and 146 CaseTrust matches (vendor dataset, checked 21 Oct 2026; CaseTrust list valid 21 Oct 2026).

Do HDB fees appear here?

HDB’s application page does not state a renovation permit fee amount (checked 4 Nov 2026). An administrative fee (amount not stated) may apply if unauthorised work is later retained; a floor-plan copy is listed at $5.

Will KeyKaki averages appear later?

Only from consented anonymised quotes once that index is running — not before.
