Introduction
HDB flats are the most common type of housing in Singapore. If you’re planning to carry out major renovations—like wall demolition or floor hacking—getting an HDB hacking permit is not just recommended, it’s required by law. Unauthorized hacking can lead to serious penalties and may compromise your home’s structural integrity.
In this blog, we’ll walk you through everything you need to know about applying for an HDB hacking permit: the process, rules, timeframe, and tips for a smooth renovation.
What is an HDB Hacking Permit?
An HDB hacking permit is official approval from the Housing & Development Board (HDB) that allows homeowners to perform hacking works such as:
- Removing walls (partial or full)
- Hacking floor or wall tiles
- Dismantling structures like built-in cabinets that affect wall integrity
Without a permit, you cannot proceed with these works legally, even if you’ve hired a contractor.
Why Do You Need an HDB Hacking Permit?
Here are key reasons why the permit is essential:
- Safety: HDB buildings have load-bearing walls. Unauthorized hacking can damage structural components.
- Compliance: It’s a legal requirement enforced by HDB.
- Avoid Penalties: Hacking without approval can result in fines, renovation stoppage, or being ordered to restore the flat.
- Insurance & Resale: Illegal renovations may affect insurance claims and HDB resale approval.
Types of Hacking Works That Require a Permit
You need a hacking permit if your renovation includes:
- Removing non-load bearing walls
- Hacking floor tiles or wall tiles
- Dismantling fixtures attached to structural walls
- Enlarging doorways or modifying toilet/kitchen layouts
🔍 Note: You cannot hack load-bearing walls or reinforced concrete slabs—even with a permit.
Step-by-Step: How to Get an HDB Hacking Permit
Here’s a simple breakdown:
Step 1: Engage an HDB-Registered Renovation Contractor
Only HDB-licensed renovation contractors are allowed to apply for a hacking permit. Ensure your contractor is on the official HDB Directory of Renovation Contractors.
✅ If you’re working with AL Interior Renovation, you’re in good hands—we’re HDB-approved!
Step 2: Submit the Renovation Application
Your contractor will submit the renovation application via the HDB e-Service portal.
Details required:
- Your HDB flat address
- Type of hacking work planned
- Floor plan with hacking areas highlighted
- Estimated start and end dates
Step 3: HDB Review & Site Inspection (if needed)
Once submitted:
- HDB will review the proposal.
- In some cases, an officer may conduct a site inspection to evaluate structural risks.
Timeframe:
📅 Typically takes 1 to 3 working days for approval.
Step 4: Receive Hacking Permit
Once approved, HDB will issue a Renovation Permit with:
- Approval dates
- Scope of approved work
- Do’s and Don’ts during renovation
📌 Keep a printed copy of this permit on-site for inspection during renovation.
Step 5: Notify Your Neighbors
As part of HDB rules:
- You must inform your neighbors at least 3 days before hacking work begins.
- A notice should be posted on your lift lobby and outside your flat.
Step 6: Follow HDB Renovation Rules
Make sure your contractor follows HDB’s renovation guidelines:
- Work hours: Mon–Sat, 9 AM to 5 PM only
- No works on Sundays and Public Holidays
- Noise control measures must be taken
What Happens If You Don’t Get a Permit?
Doing hacking work without a permit can lead to:
- Stop-work orders
- Fines and penalties

- Potential disqualification from selling or renting your HDB flat
