A typical renovation timeline in Singapore runs 6 to 12 weeks for an HDB flat, and 10 to 16 weeks for a condo or landed home, depending on scope. Permit approvals, hacking, and custom carpentry add the most time. Cosmetic touch-ups finish faster, while full renovations with structural changes take longer to complete.This guide is for informational purposes. Prices and regulations may change — always verify with HDB, BCA, or your interior designer.<h3>What Determines Your Renovation Timeline in Singapore</h3>Your renovation timeline depends mainly on scope, property type, and how quickly approvals come through. A cosmetic refresh — new paint, flooring, and fittings — moves faster than a full renovation involving hacking and rewiring. Meanwhile, custom carpentry like built-in wardrobes or kitchen cabinets often becomes the longest lead-time item in the whole project. If you're just starting your search, a <a href="https://www.renonation.sg/">Singapore renovation portal</a> makes it easy to compare timelines and contractor reviews before you commit.<figure class="image"><img style="aspect-ratio:1562/1172;" src="https://d213h1b7vxzzl3.cloudfront.net/editor/57e7a888-233d-4554-a92e-687358e40cf3-blob" width="1562" height="1172"></figure>Design: <a href="https://www.renonation.sg/professionals/blend-by-imc">BlendbyImC</a>Your contractor's workload also affects your start date, since popular firms may book out 4 to 8 weeks in advance. As a result, confirming your contractor early — ideally right after you collect your keys — helps you lock in a realistic schedule. Use Renonation.sg to <a href="https://www.renonation.sg/professionals">compare renovation contractors</a> and check each firm's current booking lead time before signing.Renovation scope generally falls into three categories: cosmetic, semi-full, and full renovation with hacking. A cosmetic refresh — repainting, new light fixtures, and minor touch-ups — can wrap up in 2 to 3 weeks. A semi-full renovation, covering new flooring and some carpentry without hacking, typically takes 4 to 6 weeks. A full renovation with hacking, rewiring, and custom carpentry across multiple rooms usually needs 8 to 12 weeks from start to handover.<h3>HDB Renovation Timeline: Week-by-Week Breakdown</h3>Below is a general week-by-week timeline for a standard 4-room HDB renovation involving hacking, new flooring, and carpentry.<figure class="image"><img style="aspect-ratio:1824/1216;" src="https://d213h1b7vxzzl3.cloudfront.net/editor/4253c142-e7b4-4b6a-8847-856f0798a9f2-blob" width="1824" height="1216"></figure>Design: <a href="https://www.renonation.sg/professionals/the-real-design">The Real Design</a>&nbsp;<figure class="table"><table><tbody><tr><td>Phase</td><td>Typical Duration</td><td>What Happens</td></tr><tr><td>Permit Application &amp; Design</td><td>1–2 weeks</td><td>HDB permit, design confirmation, material selection</td></tr><tr><td>Hacking &amp; Demolition</td><td>3–5 days</td><td>Wall removal, old tile removal</td></tr><tr><td>Electrical &amp; Plumbing</td><td>1 week</td><td>Rewiring, pipe rerouting</td></tr><tr><td>Carpentry (Built-in)</td><td>3–5 weeks</td><td>Custom wardrobes, kitchen cabinets, fabrication offsite</td></tr><tr><td>Flooring &amp; Tiling</td><td>1 week</td><td>Laying tiles or vinyl flooring</td></tr><tr><td>Painting &amp; Finishing</td><td>3–5 days</td><td>Wall painting, touch-ups</td></tr><tr><td>Final Handover &amp; DLP Start</td><td>1–2 days</td><td>Walkthrough, defects checklist</td></tr></tbody></table></figure>Source: Renonation.sg contractor project timelines, 2026Carpentry usually runs in parallel with other phases since cabinets are fabricated offsite while hacking and electrical work happen on-site. Consequently, a well-coordinated contractor can compress the total timeline to around 6 to 8 weeks for a standard 4-room flat. However, BTO flats often take longer than resale units because everything is built from scratch.<h3>Condo and Landed Renovation Timelines: What's Different</h3>Condo renovations usually add 1 to 3 weeks compared to HDB flats because of MCST approval requirements and stricter renovation hours. Most condo management corporations restrict hacking and noisy work to weekdays, which slows down projects that need weekend flexibility. Landed properties take the longest, especially when structural additions or extensions require URA planning permission.

This is a completely different timeline from a standard interior renovation, so clarify your scope with your architect early.<h3>Permit and Approval Timelines (HDB, BCA, MCST, URA)</h3>HDB renovation permits typically take 3 to 5 working days to process once you submit your application with your contractor's details. BCA (Building and Construction Authority) — the agency overseeing building safety — gets involved when your renovation affects structural elements, which can add another 1 to 2 weeks for review. MCST approval for condos usually takes 1 to 2 weeks, though this varies by management corporation.

Because these timelines run before any physical work begins, submit your applications as early as possible. Overlapping the approval wait with your design and material selection phase saves you weeks overall.<h3>How to Avoid Common Delays</h3>Material shortages remain one of the most frequent causes of delay, especially for imported tiles or specific hardware finishes. Ordering materials as soon as your design is confirmed, rather than waiting until hacking finishes, protects your schedule. Similarly, confirm lead times with your contractor in writing before signing the contract.Scope creep — adding extra work mid-renovation — also pushes back your handover date significantly. Therefore, finalise your design and material choices before work begins, and treat mid-project changes as the exception rather than the norm. Building in a 1 to 2 week buffer in your personal planning, such as moving day or lease end date, protects you from last-minute scrambling.Poor communication with your contractor also causes hidden delays, especially when site visits or approvals depend on your timely responses. Set a fixed weekly check-in, either in person or over WhatsApp, so small issues get flagged before they snowball. Additionally, avoid scheduling your renovation start date too close to a public holiday period, since many contractors and suppliers slow down during festive seasons like Chinese New Year.<h3>Frequently Asked Questions About Renovation Timelines in Singapore</h3>How long does a renovation take in Singapore? Most HDB renovations take 6 to 12 weeks, while condo and landed renovations take 10 to 16 weeks or longer. The exact renovation timeline in Singapore depends on your scope, carpentry lead time, and permit approvals. Full renovations with hacking take longer than cosmetic refreshes.How long does an HDB renovation permit take to approve? HDB renovation permits typically process within 3 to 5 working days once submitted correctly. Delays usually happen when the application is missing contractor details or renovation plans. Submit your permit as early as possible to avoid pushing back your start date.Why do condo renovations take longer than HDB renovations? Condo renovations often need MCST approval and must follow restricted renovation hours set by the management corporation. These rules limit hacking and noisy work to specific weekday windows, which slows progress. Larger units may also involve more extensive finishes.What's the longest part of a typical renovation? Custom carpentry, such as built-in wardrobes and kitchen cabinets, is usually the longest lead-time item. Fabrication can take 3 to 5 weeks depending on your contractor's workload and design complexity. Ordering carpentry early, right after your design is confirmed, helps prevent bottlenecks.Can I speed up my renovation timeline? Yes — confirming your contractor early, ordering materials in advance, and finalising your design before work starts all help. Avoiding scope creep during the renovation also keeps your project on schedule. A well-coordinated contractor can run carpentry and site work in parallel to save time.How long does URA approval take for landed property additions? URA approval for Addition and Alteration (A&amp;A) works typically takes 2 to 6 months, depending on complexity. This is separate from your actual construction timeline, so factor it in when planning a landed renovation. Engaging an architect early can help streamline the submission process. &nbsp;<blockquote>Ready to Start Your Renovation?Ready to start? <a href="https://www.renonation.sg/get-free-quote">Compare renovation quotations</a> from HDB-licensed and MCST-approved professionals matched to your timeline and budget.
