A successful condo renovation in Singapore starts with the current renovation pack from your estate’s Management Corporation Strata Title, or MCST. Check the estate rules before freezing the design or accepting a quotation. The pack can affect working hours, contractor access, lift booking, protection works, deposits, insurance and the documents needed before work begins.
For early planning, allow roughly 6 to 10 weeks on site for a new or lightly renovated condo and 8 to 14 weeks or more for a resale or full-scope condo. Published cost estimates are much wider: Qanvast’s current planning ranges, summarised in our cost guide, are about $40,000 to $52,000 for a new condo and $80,000 to $105,000 for a resale condo. These are benchmarks, not quotations. Your existing finishes, floor area, demolition, wet works, carpentry, specifications and estate requirements determine the real scope.
Condo Renovation At A Glance
| Decision | What to confirm before signing |
|---|---|
| Estate rules | Current MCST application form, by-laws, work hours, access, protection and disposal rules |
| Design | What stays, what goes, what changes, and whether any wall or external feature is affected |
| Approvals | MCST consent plus any Qualified Person, BCA, URA or other authority requirement for the actual work |
| Budget | Itemised work, quantities, materials, estate charges, exclusions, GST treatment and contingency |
| Programme | Application lead time, material lead time, work sequence, inspections, defect rectification and move-in buffer |
| Contractor | Condo experience, clear responsibility for submissions, insurance, supervision and written variations |
The key principle is simple: do not treat MCST approval as the only approval. It is the estate-level control. Structural, planning, fire-safety or other requirements may still apply depending on what you want to change.
What Makes A Condo Renovation Different From HDB?
HDB publishes a central renovation framework for public flats. A condominium is private strata property, so the renovation process also depends on the by-laws and operating rules of that particular estate.
The Building and Construction Authority explains that a condo owner is a subsidiary proprietor and must comply with the MCST’s by-laws. BCA also advises owners to check the developer, MCST and Sale and Purchase Agreement for renovation restrictions before work starts. Read BCA’s current condo-owner guidance before assuming that a proposal is internal and therefore unrestricted.
Two neighbouring condos can have different application forms, deposits, contractor access windows and protection requirements. That is why a contractor’s experience in another estate cannot replace the current pack for yours.
What Is An MCST?
The Management Corporation Strata Title manages the common property and estate rules in a strata development. As an owner, you own your strata lot and share responsibility for the common property. Renovation work can affect lifts, corridors, external walls, waterproofing, structure, noise and neighbouring units, so the MCST or managing agent normally controls site access and estate-level conditions.
Ask the managing agent for the latest renovation application material before the quotation is finalised. Do not rely on a seller’s old copy or a contractor’s form from a different development.
Get These Documents Before You Freeze The Design
Request the current estate requirements and confirm which items apply to your unit. Common examples include:
- Renovation application form and submission checklist
- Permitted work and noisy-work hours
- Contractor registration, insurance or indemnity requirements
- Refundable renovation deposit and any non-refundable charges
- Lift booking, loading-bay and delivery arrangements
- Common-area, lift and floor protection standards
- Debris removal, cleaning and daily access rules
- Drawings, method statements or professional endorsements required
- Inspection, damage reporting and deposit-refund process
- Rules for external windows, grilles, awnings, air-conditioning equipment and visible finishes
The list varies by estate. Record each requirement in the quotation so you can see whether the contractor includes it, coordinates it, or expects you to pay the managing agent directly.
Which Condo Works Need More Than MCST Approval?
Some internal work may be straightforward. Other proposals need professional assessment or authority approval. The deciding factor is the actual work, not the room name.
Structural Elements
BCA states that structural elements such as slabs, beams, columns and walls cannot be altered without proper assessment by a Professional Engineer. Approval from the Commissioner of Building Control is also required for structural alteration work. If any wall, slab opening, staircase or structural element is involved, obtain written professional advice before demolition is priced or scheduled.
BCA’s current guide to building works and exemptions also advises private-property owners to consult a Qualified Person about the clearances required for the intended works. An exemption from BCA plan submission does not remove the need to follow MCST by-laws, safety duties or another agency’s requirements.
Planning Permission And Gross Floor Area
URA states that internal works within a non-conservation strata-titled residential unit generally do not require planning permission when they do not increase gross floor area and the home remains a single self-sufficient residential unit. Works that increase gross floor area follow a different process. URA requires an MC authorisation supported by a 90 per cent resolution as part of that planning application.
Check URA’s current strata-titled residential renovation guidance before enclosing, covering or adding usable floor area. Conservation properties and unusual proposals can have additional requirements.
External Features And Common Property
Windows, external walls, facade elements, common pipes and other shared or visible features may be common property or controlled by the estate. BCA notes that alterations to features fixed to the external building require MCST approval and any relevant government approvals. Do not order windows, grilles, awnings or external equipment until the ownership and approval path are confirmed.
How Much Does A Condo Renovation Cost In Singapore?
Use published ranges only to set an early planning zone. Our HDB versus condo renovation cost guide summarises Qanvast’s current broad estimates:
| Condo condition | Published planning range | Why the scope changes |
|---|---|---|
| New condo | About $40,000 to $52,000 | Developer flooring, kitchen, wardrobes or sanitary fittings may be retained |
| Resale condo | About $80,000 to $105,000 | Removal, repairs, rewiring, plumbing, waterproofing and replacement work can expand the scope |
Your quotation can sit below or above these figures. A compact new unit that retains most finishes is a different job from an older condo with two bathrooms, full hacking, rewiring and custom carpentry.
Budget For Estate Requirements Separately
Ask the managing agent to identify which payments are refundable and which are not. Depending on the development, you may encounter:
- A refundable renovation deposit
- Administrative or application charges
- Lift, access or common-area protection requirements
- Professional endorsement or drawing costs
- Additional cleaning or damage charges when rules are not followed
Do not describe a refundable deposit as part of the renovation cost, but make sure your cash-flow plan can carry it. Put non-refundable charges and required professional services into the project budget.
Keep A Contingency For The Actual Unit
A resale condo can reveal uneven substrates, failed waterproofing, concealed leaks, old wiring or damaged services after removal. Our renovation budget planning guide explains how to separate essential works, optional upgrades and contingency before comparing quotes.
How Long Does A Condo Renovation Take?
Use these ranges as planning estimates after the design, approvals and major materials are settled:
| Scope | On-site planning estimate | Common time risks |
|---|---|---|
| Focused room refresh | 2 to 6 weeks | Custom carpentry, wet works, access and material lead times |
| New or lightly renovated condo | 6 to 10 weeks | MCST approval, retained finishes, protection, deliveries and carpentry |
| Resale or full-scope condo | 8 to 14 weeks or more | Hacking, repairs, waterproofing, rewiring, plumbing, custom finishes and inspections |
The application period sits before on-site work. Do not promise an approval duration until the managing agent has checked a complete submission. Estate rules, professional endorsements and revisions can change the start date.

A Practical Condo Renovation Sequence
1. Inspect What You Already Have
Record what can be retained, repaired or removed. In a new condo, inspect developer finishes and report defects before renovation work obscures them. In a resale condo, check signs of water damage, old electrical work, plumbing condition and uneven floors.
2. Get The Current MCST Pack
Read the application requirements before finalising layout changes, deliveries or the contractor’s programme. Highlight every item that affects drawings, price, access or timing.
3. Confirm The Approval Path
Mark the proposed work on the plan. Ask which items need only estate consent, which need a Professional Engineer or Qualified Person, and which need BCA, URA, SCDF or another authority. Keep written evidence of the answer.
4. Build One Measurable Scope
List retained and removed items, rooms, dimensions, quantities, materials, electrical points, plumbing work, protection and exclusions. A shared scope makes different quotations comparable.
5. Submit Before Ordering Around A Fixed Start Date
Do not promise movers, furniture deliveries or handover dates until the application and key materials are sufficiently certain. A provisional construction window is safer than pretending an unapproved start is fixed.
6. Protect, Build And Inspect In Sequence
Confirm common-area protection before deliveries. Complete approved demolition and concealed services before closing walls or laying finishes. Test waterproofing and services at the appropriate stages. Record defects at handover and agree the rectification schedule in writing.
Room-By-Room Priorities For Condo Owners
Kitchen
Decide whether developer cabinets, flooring and appliances can be retained. Confirm whether an open-kitchen proposal affects walls, services, fire-safety provisions or estate rules. Price cabinetry by measured length and specification, not by a generic package label.
Bathrooms
Treat waterproofing, floor falls, pipe condition and ventilation as higher priorities than decorative fittings. Water seepage can affect the unit below, so record the contractor’s waterproofing scope, testing method and warranty.
Living And Dining Areas
Check floor condition, power points, lighting, air-conditioning routes and built-in storage before styling decisions. Large-format finishes, concealed details and feature carpentry can increase cost even when the room looks simple.
Bedrooms And Storage
Plan circulation around wardrobes and beds. Confirm air-conditioning access, power points and future maintenance clearances before fixing full-height carpentry.
For dependencies across the whole home, use the room-by-room renovation guide alongside your floor plan.
How To Compare Condo Renovation Quotes
Each quotation should state:
- The same rooms, retained items and demolition scope
- Measured quantities for flooring, worktops, cabinets and electrical points
- Material brand, model, size, thickness, finish or allowance
- MCST application responsibility and document preparation
- Protection, lift booking, access and disposal assumptions
- Professional fees, authority fees and estate charges included or excluded
- GST treatment and final amount payable
- Written variation process and unit rates where practical
- Payment stages tied to completed work
- Start assumptions, work sequence and handover buffer
- Warranty, defect reporting and rectification responsibility
Our renovation quote comparison guide gives a fuller like-for-like framework. The cheapest total is not meaningful until the scope and exclusions match.
How To Choose A Condo Renovation Contractor
Ask for evidence that the contractor can manage your actual scope and estate conditions. Useful questions include:
- Who will obtain and prepare the MCST submission?
- Which proposed works need professional assessment or authority approval?
- What estate costs, protection and access work are included?
- Who supervises waterproofing, electrical and plumbing work?
- How are existing defects and concealed conditions recorded?
- How are variations approved and priced?
- What happens if the application or a material delivery delays the start?
A contractor should be willing to separate confirmed facts from assumptions. Be cautious when anyone promises a fixed approval time before reading the current estate requirements.
Frequently Asked Questions
What approvals do I need before renovating a condo in Singapore?
Start with the current MCST renovation pack and obtain estate consent where required. The actual work may also need professional assessment or approvals from BCA, URA, SCDF or another authority. Structural elements cannot be altered without the proper professional and building-control process.
How long does MCST renovation approval take?
There is no single Singapore-wide approval period because each estate controls its own submission process. Ask the managing agent for the current checklist and processing expectation, then allow time for missing documents, professional endorsements and revisions.
Can I hack a wall inside my condo?
Do not assume an internal wall is non-structural. BCA states that slabs, beams, columns and walls cannot be altered without proper assessment by a Professional Engineer, and structural alteration work requires the relevant building-control approval. Check the proposal before pricing or scheduling demolition.
How much should I budget for a condo renovation?
Published Qanvast ranges are about $40,000 to $52,000 for a new condo and $80,000 to $105,000 for a resale condo. Treat them as broad planning benchmarks. Your floor area, existing finishes, demolition, wet works, carpentry, specifications and estate requirements determine the quotation.
How long does a full condo renovation take?
A new or lightly renovated condo may need about 6 to 10 weeks on site. A resale or full-scope condo may need 8 to 14 weeks or more. Add design, application, procurement, inspection and move-in buffer time before and after construction.
Can I live in the condo during renovation?
It may be possible for a small, isolated scope, but full-home hacking, wet works, electrical work, dust and restricted access usually make occupation impractical. Ask the contractor to explain safety, water, power, ventilation and daily cleaning arrangements before deciding.
Are condo renovation packages different from HDB packages?
They can be. Condo scopes must account for existing developer finishes or resale conditions as well as estate-specific application, protection, access and deposit requirements. Compare the measured work and exclusions rather than relying on the package name.
Plan The Estate Rules And The Home Together
A condo renovation is not just an interior-design exercise. The best plan connects the unit’s condition, the estate rules, the approval path, the measured scope and the move-in date before work begins.
