Updated 26 Sep 2026. A home can fit your purchase budget and still leave you short of cash before you move in. The useful renovation number is the amount you can spend after completing the purchase, protecting your household reserve and paying for everything needed to live in the home.
This guide helps you build that number from your own scope and quotations. It does not present a national renovation price list: two homes with the same floor area can require very different work.
Start with cash that will actually be available
Prepare two separate budgets. The first covers the purchase and its completion payments. The second begins with the cash left afterwards and covers renovation, furnishing and the move. Do not put an expected bonus, an uncompleted sale or a refundable deposit in the second budget as though the money is already available.
CPF Board expressly states that CPF savings cannot pay for renovation, improvement or repair work. A healthy Ordinary Account balance therefore does not fill a renovation cash shortfall. Check your proposed funding against the CPF renovation restriction before signing a works contract.
Choose a household reserve that reflects your actual essential bills, dependants and income reliability. Keep it separate from the amount available for the project. If you are buying as a couple, agree which account pays each bill and who can authorise extra work.
A worked move-in budget
The following is a hypothetical household plan, not a contractor quotation, market average or recommended minimum. Assume S$90,000 of cash remains after all purchase commitments have been paid or separately reserved. The household chooses to protect S$25,000, leaving S$65,000 for the move-in project. All assumed expenses below include any applicable GST.
| Item | Assumed cash |
|---|---|
| Contracted renovation works | S$40,000 |
| Furniture and appliances | S$10,000 |
| Moving and temporary accommodation | S$5,000 |
| Contingency for unconfirmed work | S$8,000 |
| Total project allocation | S$63,000 |
| Unallocated cash within the S$65,000 project budget | S$2,000 |
The S$8,000 contingency is part of the S$63,000 allocation, not an extra fund to add again. It is also separate from the protected S$25,000 household reserve. If a subsequent quote adds S$6,000 of necessary work, the household must identify which allowance absorbs it or reduce the scope. Calling the extra work an upgrade does not create more cash.
The reserve and contingency here are choices for this example. An older home with uncertain concealed services may need a different allowance from a home where the work is limited to loose furniture and painting.
Compare the same work before comparing the price
Give each contractor the same room-by-room brief. List what stays, what is removed, what must function on move-in day and what can wait. Ask the quotation to identify quantities, materials, fittings, finishes and exclusions. An attractive total is difficult to assess if one quotation includes electrical work, disposal and protection while another leaves them open.
- Kitchen: confirm cabinet measurements, worktop scope, appliances, sink, plumbing connections and who supplies each item.
- Bathrooms: distinguish cosmetic replacement from hacking, waterproofing and pipe work. Ask what inspection or testing is included and what happens if an existing defect is discovered.
- Electrical and air-conditioning: list points, equipment, trunking and any work retained from the existing installation. Clarify who checks suitability.
- Completion: include debris removal, cleaning, touch-ups and a written defects process. Establish who is responsible when a separately purchased appliance does not fit.
For uncertain items, ask for the basis of the allowance and how the final price will be measured. Record agreed variations, their prices and their effect on completion before authorising them. Keep the original scope so you can see whether a variation is genuinely new work.
Check the actual approval route
For HDB flats, HDB says to engage a contractor listed in its Directory of Renovation Contractors. Some work needs a renovation permit and some does not; work without a permit requirement must still comply with HDB’s guidelines. Ask the contractor to identify the proposed items requiring permission and show the relevant approval before work starts. See HDB’s current renovation requirements.
For a condo, obtain the estate’s current renovation application, by-laws and requirements from management before agreeing a start date. Ask about access, working arrangements, deposits and protection of shared areas. Approval from one party should not be assumed to cover every structural, statutory or estate requirement. For significant alterations, including landed-home work, ask the relevant qualified professional to identify the approvals needed for that particular scope.
Do not schedule a moving truck around an assumed universal approval period. Put approval, site access, material delivery and inspection dependencies on the programme and identify who will confirm each one.
The payment dates matter as much as the total
Put the contractor’s proposed payment stages on a calendar beside furniture deposits, appliance balances and accommodation bills. Define each milestone in writing: “carpentry delivered” and “carpentry installed and checked” are different events. Read the cancellation, delay, variation and defects clauses before accepting the schedule.
Ask what evidence you can inspect before each payment falls due. Photograph completed stages and retain receipts. A final payment or retention arrangement should be negotiated and written into the contract; this guide does not assume a mandatory retention percentage or warranty period.
If financing is proposed, request the effective interest rate, fees, total repayment and payment dates for your actual offer. Then add the new monthly commitment to the mortgage and ordinary household bills. A loan changes when you pay; it does not reduce the price of the works.
Make the home usable before making it complete
Walk through a normal weekday. Can everyone shower, cook, sleep and work while the remaining jobs are unfinished? Will an elderly parent have a clear route to the bathroom? Where will children study if installation is delayed? Decide which work must happen before occupation and which furniture or decorative features can wait.
For a rental property, assess durable, maintainable finishes and the time needed to make the unit usable. Do not budget on an assumed rental premium for expensive fittings. For your own home, avoid deleting practical storage or necessary repairs just to retain a decorative feature.
Before committing, you should have an affordable written scope, an approval route, a payment calendar and a plan for a delayed move. If the project only works by spending the emergency reserve, reduce or phase the scope before signing.
