Condominium renovation in Singapore looks similar to HDB renovation on the surface — same trades, same materials, often the same contractors — but the rules, approvals and hidden costs are meaningfully different. Homeowners moving from an HDB into a private condo are often surprised that what cost S$60,000 in their previous flat now costs S$90,000 in their new condo, with no obvious upgrade in finishes.
The reasons are mostly structural: condos are governed by MCST (Management Corporation Strata Title) rules instead of HDB rules, the building approvals work differently, and access logistics — lifts, loading bays, hours, security — add cost that doesn’t exist in an HDB block. This guide explains what to expect, what to budget for, and what’s genuinely different. Written by the team at RS Carpentry, an HDB and BCA-registered contractor delivering condo renovations across Singapore.
MCST Rules vs HDB Rules: The Key Differences
HDB rules are standardised across all blocks. MCST rules are set by each individual condominium’s management council, which means every condo has its own renovation regulations. Common differences from HDB:
- Tighter working hours. Many condos restrict noisy works to 9am–5pm weekdays only, with no Saturday work.
- Renovation deposits. Most condos require a refundable deposit of S$1,000–S$5,000 to cover potential damage to common areas.
- Lift booking and protection. Renovation access uses dedicated cargo lifts in many condos; both must be booked in advance.
- Hours-of-work restrictions during festive periods. CNY, Christmas and Hari Raya may impose extra restrictions.
- Approval of contractor. Some condos require contractors to register with the MCST and submit insurance documentation.
- Restrictions on external works. Window replacement, balcony grilles and AC installation may need additional architectural board approval.
Always request the condo’s renovation guidelines from your management office before signing any contractor quote. Different rules can affect both timeline and cost.
Approvals Beyond MCST: When BCA Gets Involved
For most cosmetic renovations — kitchen, bathrooms, carpentry, paint, lighting — MCST approval is sufficient. But for any work involving structural changes, the Building & Construction Authority (BCA) may also need to approve.
Examples of work requiring BCA submission:
- Hacking of any non-structural wall taller than 1.2m
- Any change to the external facade (windows, balcony enclosure, AC ledge alterations)
- Wet-area conversions (turning a dry area into a bathroom)
- Kitchen relocations involving plumbing risers
- Loading changes — large stone slabs, heavy bathtubs
BCA submissions add 2–6 weeks to the timeline and require a Qualified Person (Professional Engineer or Architect) to certify drawings. A reputable contractor will tell you upfront whether your scope needs BCA — and an unscrupulous one will quietly skip it, leaving you exposed to legal and resale issues later.
Why Condo Renovations Cost More Than HDB
Five factors typically push condo renovation costs 15–30% above an HDB renovation of equivalent floor area:
- Higher ceiling heights. Many condos sit at 2.7m–3.0m versus 2.4m–2.6m in HDB. More wall paint, taller carpentry, more material per linear foot.
- Premium expectations. Most condo owners specify higher-grade tiles, sintered stone instead of quartz, full sintered-stone vanities, and imported sanitary ware.
- Access logistics. Cargo lift booking fees, longer haul distances from loading bay to unit, multiple trips per day.
- Strict noise restrictions. Spread the same work over more days at lower hourly intensity, increasing labour cost.
- External works complexity. Window replacement, AC installation and balcony works often require gondola access — significant cost.
Realistic Condo Renovation Cost in Singapore (2026)
Condo renovation pricing varies more than HDB because unit sizes, finishes and scope vary far more. Realistic 2026 ranges for a complete renovation including light hacking, full carpentry and quality finishes:
- 1-bedroom (500–650 sqft): S$45,000–S$80,000
- 2-bedroom (700–900 sqft): S$70,000–S$120,000
- 3-bedroom (1,000–1,200 sqft): S$90,000–S$170,000
- 4-bedroom / penthouse (1,400+ sqft): S$130,000–S$280,000+
Carpentry typically represents 35–45% of the total spend in condo renovations — wardrobes, kitchen cabinets, full-wall TV joinery and bathroom vanities.

Hidden Condo Renovation Costs to Budget For
- Refundable MCST renovation deposit: S$1,000–S$5,000 (cash flow consideration even though it’s refundable)
- Cargo lift booking fees: S$30–S$80 per session, sometimes daily
- Common-area cleaning levy: S$300–S$1,200 charged by some MCSTs
- BCA submission fees: S$1,500–S$5,000+ if structural changes are involved
- Qualified Person fees: for BCA-required engineering certification
- Gondola hire for window or external facade works
- After-hours surcharge if any work runs past condo-approved hours

Condo Renovation Timeline: What’s Realistic
Condo renovations consistently run 2 to 6 weeks longer than equivalent HDB scopes. The drivers:
- Restricted working hours: Stretches the same labour over more calendar days
- BCA approvals if applicable: Adds 2–6 weeks for structural changes
- Cargo lift contention: When multiple units in the same condo are renovating
- External works dependent on weather: Window replacement, gondola work paused in heavy rain
A realistic schedule for a typical 3-bedroom condo (1,000 sqft, full renovation, light hacking) is 12 to 16 weeks of site work, plus 3 to 5 weeks of pre-site approvals and design.

Choosing a Contractor That Understands Condo Work
Not every HDB renovation contractor is set up for condo work. Things to ask before signing:
- BCA registration in addition to HDB registration
- Experience with the specific condo, or comparable buildings
- Familiarity with MCST submission processes
- Public liability and contractors all-risk insurance
- References from condo projects, not just HDB
- CaseTrust accreditation for consumer protection
RS Carpentry is HDB-registered (HB-05-5960D), BCA-registered and CaseTrust-accredited — and we handle MCST submissions, deposit coordination and lift booking as part of our standard scope on condo projects. You can read genuine homeowner feedback across HDB and condo projects on our reviews page.
