Condo Renovation Timeline in Singapore: What's Realistic (2026)

A condo renovation in Singapore takes 8 to 12 weeks of site work for a typical three-bedroom unit — plus 1 to 3 weeks of MCST approval and 4 to 6 weeks of design before that. End to end, from first design meeting to move-in, a realistic plan is 4 to 6 months. Light scopes without hacking finish in 6–8 weeks on site; full overhauls of older resale units run 10–14.

Condos carry scheduling constraints that HDB flats don't — approval queues, lift bookings, tighter noise windows — and they're the reason two identical scopes can finish a month apart. Here's the realistic schedule, phase by phase.

How long does a condo renovation take?

Plan for 8–12 weeks on site for a standard scope. By scope:

• Light refresh (carpentry, painting, no wet works): 6–8 weeks
• Standard renovation (full carpentry, some hacking, one bathroom): 8–12 weeks
• Full overhaul (older resale unit, rewiring, re-plumbing, all wet areas): 10–14 weeks

New-launch units sit at the light end — the developer's finishes are new, so work is mostly additive. Do the defects inspection before works begin, while the developer still owes you the fixes. Resale units carry a demolition and make-good phase that new units skip entirely; our new launch vs resale renovation guide covers that gap in detail.

What does the phase-by-phase schedule look like?

For a standard three-bedroom scope with some hacking and one bathroom redone:

Why do condo renovations take longer than HDB ones?

Three structural reasons: shorter noisy-work windows, lift and access logistics, and the MCST approval gate. Most condos restrict noisy works to roughly 9am–5pm weekdays with a lunchtime quiet break — several working hours fewer per week than an HDB site gets. Materials queue for a padded lift instead of a corridor, and nothing starts until the approval letter lands. Together they add 10–20% to the schedule for the same scope. (Renovating a BTO instead? The equivalent schedule is in our BTO renovation timeline guide.)

What delays a condo renovation most often?

Mid-project design changes remain the number one cause of delay, followed by imported material lead times and approval amendments.

• Design changes after fabrication starts: 1–3 weeks lost each time
• Imported tiles, sintered stone, specialty fittings: 4–8 week lead times — order at design stage
• Scope amendments with the MCST: adding hacking or wet works mid-project means a fresh review
• Lift booking contention: in newer developments with several concurrent renovations, delivery slots become the bottleneck
• Chinese New Year: crews and suppliers close 1–2 weeks

How do you plan a condo renovation schedule properly?

Lock the design, secure the approval, then start — never the other way around. In order:

1. Start design 3–4 months before your target move-in
2. Collect your condo's renovation guidelines early; every MCST differs
3. Submit the MCST application the moment scope is final
4. Order long-lead materials the same week
5. Ask for a written weekly schedule with photo updates — it's how we run every project in our condo interior design service

If you want a schedule mapped to your actual unit and scope, request a free design proposal — timeline planning is part of it, not an extra.

The bottom line

Eight to twelve weeks on site, one to three for approval, four to six for design: count backwards from your move-in date and the right time to start is about four months out. The schedule killers are late decisions, late orders and late applications — all three are avoidable, and none of them are construction.
