A complete 2026 reference covering renovation cost ranges by property type and size — HDB BTO from S$25k, resale HDB from S$40k, new condo from S$35k, resale condo from S$55k — with trade-by-trade breakdowns, permit rules, loan options, and a practical budgeting checklist (as of 2026-06).
Signing the keys is the easy part. The harder question — one that shapes your cash flow for the next three to five years — is how much it will actually cost to make the unit liveable, and how to keep that number from climbing 30% above your first quote. Singapore renovation costs in 2026 are running high: labour is tight, material costs have not fully retreated from post-pandemic peaks, and the queue for good contractors stretches months. Yet the spread between a thoughtfully scoped job and an open-ended one can easily be S$50,000 or more on the same flat. This guide cuts through the noise with real indicative ranges segmented by property type, flat size, and finish tier, so you can build a credible budget before you ever call a contractor.
Why property type and condition change everything
No single renovation cost number makes sense without knowing two things: what type of property you own, and whether it is brand-new or resale. A new BTO or a new-launch condo arrives as a near-blank slate — basic carpentry, feature lighting, and minor flooring are often all that is needed in the first year. A resale unit built before 2005 almost always requires hacking, full rewiring, waterproofing in wet areas, and potentially window replacement on top of the cosmetic work. The gap between the two scenarios can exceed S$30,000 on a similarly sized unit.
The Singapore regulatory backdrop
Every renovation in Singapore operates within a framework of rules that affect cost and timeline. For HDB flats, the HDB renovation framework requires that all renovation works be carried out by an HDB-registered contractor. Structural walls, floor slabs, and certain wet-area configurations cannot be altered without specific permits. Works involving hacking, plumbing, or electrical changes require prior approval through the HDB renovation permit system, and noisy works are restricted to weekdays and Saturdays between 9 am and 5 pm. For condos, the Management Corporation Strata Title (MCST) governs what can be done: owners must submit renovation plans to the building management for approval before work begins, respect by-law restrictions on hacking hours (typically 9 am to 5 pm on weekdays only), and comply with building-specific rules on material types and floor coverings. For both property types, the CaseTrust accreditation scheme run by the Consumers Association of Singapore (CASE) and the Singapore Furniture Industries Council (SFIC) offers deposit protection and a dispute resolution framework — using a CaseTrust-accredited firm caps upfront deposits and gives you recourse if the contractor defaults.
2026 cost pressures
Several factors are pushing renovation costs higher in 2026. Skilled labour — particularly carpenters, tilers, and electricians — remains scarce, with many firms operating at near-full capacity. Timber and engineered wood costs have stabilised from their 2022–2023 highs but have not returned to pre-pandemic levels. Cement, tiles, and sanitary ware remain elevated. The practical effect: quotes issued in early 2025 may no longer be valid. Always get fresh quotes, and build a 10% contingency into your budget from day one.
Singapore renovation costs in 2026 typically range S$40,000–S$120,000 for HDB resale (4-room), S$60,000–S$180,000 for condo (3-bedroom), and S$200,000–S$500,000 for landed (3-bedroom terrace). Costs split roughly: 35% carpentry/built-ins, 25% wet works (kitchen + bathroom), 15% electrical + lighting, 10% flooring, 15% paint/finishes/contingency. New launch (BTO/condo) renovations average 30-40% lower as no demolition needed.

Cost breakdown by trade
Understanding where your budget actually goes is the key to controlling it. Across most renovation projects in Singapore, costs break down roughly as follows:
- Carpentry (35–45% of total budget): Kitchen cabinets, wardrobes, TV feature walls, vanity units, and display shelving are almost always the single largest cost driver. Custom full-height wardrobes in a 4-room HDB can run S$8,000–18,000 alone depending on material and internal fittings. Laminate-wrapped boards (Melamine or Compact Laminate) are standard; lacquer finishes add 20–40%.
- Masonry and flooring (15–25%): Tiling wet areas (bathrooms, kitchen) and hacking existing floor tiles adds up quickly, especially in resale units where old adhesive beds need full removal. Porcelain tiles at 60x60 cm or 80x80 cm formats are the mid-market standard. Marble and natural stone carry a 40–80% premium per sqm. For living and bedroom areas, engineered timber or vinyl plank flooring is common at S$8–18 per sqm supply-and-install for mid-range products.
- Plumbing and electrical (10–18%): New BTO and new-launch condos arrive with modern wiring; resale units — especially those more than 20 years old — often require partial or full rewiring. Expect S$3,500–8,000 for a full rewire of a 4-room HDB. Plumbing in wet areas costs S$2,000–5,000 for standard point changes; full bathroom plumbing replacement is S$3,500–7,000 per bathroom.
- Ceiling, lighting, and painting (8–12%): False ceilings (gypsum board) with cove lighting run S$18–30 per sqm installed. A full interior paint job for a 4-room HDB ranges from S$1,800–3,500 depending on number of coats and ceiling inclusion. Premium emulsion or texture finishes add 30–50%.
- Hacking and demolition (5–10% in resale only): Removing old floor tiles, demolishing non-structural partitions, or stripping out dated carpentry is a cost centre unique to resale renovations. Hacking typically costs S$3–6 per sqm for floor tiles; partition removal starts around S$400–800 per wall segment.
- Glasswork, windows, and doors (3–8%): Sliding glass panels, frameless shower screens, tempered glass partitions, and aluminium window replacement are common upgrades. A full aluminium window replacement for a 4-room HDB starts around S$4,000–7,000.
- Contingency (minimum 10%): Experienced homeowners budget 10–15% above their contractor quote for variations discovered during hacking (concealed water damage, incorrect wiring, structural surprises), design changes, and material delivery delays.
Renovation financing in 2026
A renovation loan is a separate product from your housing loan and should be evaluated independently. Most major Singapore banks (DBS, OCBC, UOB, Maybank, Standard Chartered) offer renovation loans up to S$30,000 or six times your monthly income, whichever is lower, at tenures of one to five years. Interest rates as of mid-2026 typically range from 3.88% to 6.88% per annum (EIR). The MAS consumer finance guidelines apply to all renovation loan products — compare the Effective Interest Rate (EIR), not the advertised flat rate. CPF Ordinary Account funds cannot be used for renovation; the CPF Board FAQ confirms renovation is an out-of-pocket expense. If your renovation budget is large, consider how it interacts with your overall property purchase costs using our total cost of ownership calculator before committing. For a targeted renovation cost projection, our renovation cost calculator lets you model scope, tier, and contingency in one view.
District and neighbourhood context
Renovation costs are largely determined by your contractor and project scope, not your postal district — materials and labour rates are market-wide in Singapore. However, the profile of properties available in different districts affects what a typical renovation looks like. Older resale-heavy districts (for example District 14 — Eunos/Geylang/Paya Lebar or District 19 — Serangoon/Hougang) skew toward higher-condition renovation budgets given the age of the housing stock, while newer new-launch clusters (District 18, District 23) see more BTO-style budgets.
Step by step
- Establish your budget ceiling before meeting contractors. Work backwards from how much cash you have available above your down payment and stamp duty. Factor in renovation loan limits (typically S$30,000 or 6x monthly income). Use the total cost of ownership calculator to model the full purchase picture including renovation. Decide your tier — basic, mid, or premium — before your first ID meeting so you are not upsold in real time.
- Get at least three quotes from licensed or accredited firms. For HDB: verify the contractor holds an HDB Renovation Contractor (RC) licence. For condos: check that the firm is familiar with your development's MCST requirements. Prioritise firms holding CaseTrust accreditation — it caps your upfront deposit at 10% before works commence and 20% upon commencement (for members with the Joint Mediation Scheme), providing meaningful protection if the contractor closes down mid-project.
- Scope the work in writing before signing anything. A Bill of Quantities (BQ) should itemise every item — unit price, quantity, and total — not just a lump-sum figure. Ambiguous scopes are the primary driver of variation charges. Common scope gaps: waste disposal, touch-up paint after final handover, provision for appliances, and feature light fittings.
- Apply for required permits early. HDB renovation permits are applied for by the contractor on your behalf via the HDB e-Services portal, but the timeline is your problem if approval is delayed. Allow two to four weeks for permit approval before scheduling hacking and wet works. For condos, submit your renovation plans to the MCST management office and confirm the approved working hours (typically Monday–Friday 9 am–5 pm, Saturday 9 am–1 pm; no noisy works on Sundays or public holidays).
- Add a 10% contingency line to your signed BQ. Do this before you sign, not after you discover a problem behind a wall. Common discoveries in resale units: concealed water damage at bathroom wall junctions, sub-standard original wiring that requires upgrading to comply with current SS 638 standards, and adhesive beds too thick to tile over (requiring full hacking). A pre-committed contingency prevents scope-creep anxiety mid-project.
- Sequence the trades correctly. The typical sequence is: hacking and demolition → structural/waterproofing works → plumbing and electrical rough-in → masonry and tiling → carpentry and millwork → false ceiling → painting → flooring (where soft flooring goes last) → lighting and accessories → cleaning and handover. Any deviation from this sequence risks rework charges. Confirm the schedule in writing before works begin.
- Conduct staged inspections, not just a final walkthrough. Inspect wet areas before wall tiles go up (so you can verify waterproofing was applied). Inspect carpentry before laminate skins are fitted (so you can check board quality and internal fittings). Final handover should include a detailed punch-list, and any defects must be documented in writing to the contractor before the final progress payment.
- Structure payment milestones, not lump-sum upfront. A typical payment structure: 10–20% upon contract signing, 30–40% upon commencement, 30–40% upon substantial completion, and 5–10% upon final handover and defect rectification. Never pay more than 20% before any work starts, even under pressure. CaseTrust accredited firms are contractually bound to these caps.
- Plan for temporary housing costs. Most full renovations in Singapore take six to twelve weeks. Factor in short-term rental costs (typically S$2,000–5,000 per month for a furnished room or small unit) into your total renovation budget — these are real cash outflows that are frequently overlooked in renovation planning.
- Review your renovation budget against your total cost of ownership. Use the renovation cost calculator and cross-check the total outlay with your overall property financials using our total cost of ownership calculator. A premium renovation on a unit with a modest price-to-income ratio can create meaningful liquidity pressure — model it before you commit.
Frequently asked questions
What is the average renovation cost for a 4-room HDB resale flat in 2026?
For a 4-room HDB resale flat (approximately 90–105 sqm), indicative total renovation costs in 2026 range from S$55,000–80,000 at a basic tier, S$80,000–115,000 at a mid tier, and S$115,000–160,000 at a premium tier (as of 2026-06). Resale units command higher budgets than BTO because they almost always require hacking of old tiles, rewiring of dated electrical systems, and waterproofing of wet areas that may be 20 or more years old. Always obtain a site inspection and detailed Bill of Quantities from at least three contractors before finalising your budget.
Do I need a permit to renovate my HDB flat, and how do I get one?
Yes — most structural and wet-area renovation works in HDB flats require a renovation permit issued by HDB. Your contractor, who must hold an HDB Renovation Contractor (RC) licence, is responsible for applying for the permit on your behalf via the HDB e-Services portal before work commences. Permit-required works include hacking of walls and floors, plumbing modifications, electrical rewiring, and installation of new windows. Cosmetic works such as painting, installation of furniture, and minor wall-mounted fixtures typically do not require a permit, but you should confirm with your contractor. Permits generally take two to four weeks to approve, so plan your renovation start date accordingly. Carrying out permit-required works without approval can result in reinstatement orders and fines under the HDB renovation rules.
Can I use CPF savings to pay for renovation, and what loans are available?
CPF Ordinary Account savings cannot be used to pay for home renovation — the CPF Board confirms renovation is not an approved use of CPF housing withdrawals. Renovation must be funded from cash savings or a dedicated renovation loan. Most major Singapore banks offer renovation loans up to S$30,000 or six times your monthly income (whichever is lower), at tenures of one to five years and Effective Interest Rates (EIR) typically between 3.88% and 6.88% per annum as of mid-2026. Always compare the EIR — not the advertised flat rate — across lenders, as the difference can be significant over a three-year tenure. The MAS consumer finance guidelines govern all renovation loan products in Singapore.
What does CaseTrust accreditation mean and should I only use CaseTrust-accredited firms?
CaseTrust accreditation is a quality and financial safeguard scheme administered jointly by the Consumers Association of Singapore (CASE) and the Singapore Furniture Industries Council (SFIC) under the umbrella of the BCA. Firms that hold CaseTrust accreditation are contractually bound to cap upfront deposits — typically 10% before commencement and 20% upon commencement for firms under the Joint Mediation Scheme — and must provide a contract with standard clauses protecting consumers. If a CaseTrust firm defaults mid-project, a Fidelity Insurance scheme covers a portion of your deposits. For renovation projects above S$20,000, engaging a CaseTrust-accredited firm is strongly advisable. Note that CaseTrust accreditation is separate from the HDB Renovation Contractor licence — a contractor can hold one or both, and for HDB flats you need both: the firm must be HDB-registered AND ideally CaseTrust-accredited.
How long does a full renovation typically take in Singapore, and what are the key variables?
A full renovation of a 4-room HDB or 2-bedroom condo in Singapore typically takes six to twelve weeks from first day of works to handover (as of 2026-06). Key variables that stretch the timeline include: permit approval wait times (two to four weeks before hacking can begin), material lead times (custom carpentry is typically four to six weeks from order to installation), contractor availability (top firms are often booked two to three months in advance), and defect rectification rounds at handover. For resale units with extensive hacking, add one to two weeks for the demolition and cleaning phase. Complex premium renovations with bespoke millwork, imported tiles, or smart-home integration regularly run twelve to sixteen weeks. Plan for temporary accommodation costs covering the full expected duration plus a two-week buffer.
