In Singapore, home renovation often begins with hacking works—demolishing old tiles, dismantling partitions, or removing fixtures to pave the way for new designs. While hacking is a common part of remodeling, it is not as simple as picking up a hammer and getting to work. Due to the safety risks and potential structural impact, hacking works are tightly regulated. If you’re planning a renovation, it’s essential to understand whether a license is required and what the rules are. This guide explains everything you need to know about the hacking license requirements in Singapore.
What Are Hacking Works?
Hacking works refer to the demolition or removal of existing interior elements in a home. These may include:
- Removal of floor and wall tiles
- Dismantling of built-in cabinets or fixtures
- Knocking down partition walls
- Stripping old cement screed or waterproofing layers
- Demolition of bathrooms or kitchens for reconfiguration
Because these activities may affect the structure, safety, and livability of a property, the government and building authorities regulate how, when, and by whom they can be carried out.
Is a License Required for Hacking Works in Singapore?
Yes, a license or permit is required for hacking works in certain property types, particularly HDB flats, to ensure safety and compliance with building codes.
For HDB Flats
Hacking works in HDB flats are governed by strict rules set by the Housing & Development Board (HDB):
- Only HDB-licensed renovation contractors are permitted to carry out hacking works.
- A Renovation Permit must be obtained from HDB before any hacking begins.
- Structural walls cannot be hacked under any circumstance unless explicitly approved by HDB.
- Hacking works can only be carried out during approved hours—typically weekdays between 9 AM to 5 PM.
- Contractors must submit layout plans and hacking proposals to get permission.
Performing unauthorized hacking in an HDB unit can result in:
- Hefty fines
- Forced reinstatement of the hacked area
- Blacklisting of contractors
- Possible structural damage and safety hazards
Homeowners are responsible for ensuring all necessary approvals are obtained, even if the work is outsourced.
For Condominiums
While HDB has a centralized system for renovation control, condominiums operate under Management Corporation Strata Title (MCST) rules. Although no hacking license is issued by a government body for private properties, approval is still required:
- Submit renovation plans to the condo management office for review.
- Include detailed hacking plans, especially if knocking down walls.
- Contractors must follow MCST-specific guidelines, such as protection of common areas and noise control.
- Some MCSTs may require the contractor to be BCA-registered or submit a refundable renovation deposit.
Failing to comply may lead to penalties or delays in renovation.
For Landed Properties
For landed homes, the rules are slightly more flexible, but hacking works still require oversight:
- A Building and Construction Authority (BCA) permit may be required for structural changes.
- If hacking affects load-bearing walls or external structures, a Professional Engineer (PE) endorsement may be needed.
- Renovation works should follow URA and BCA building control regulations, especially for older or conserved buildings.
While there is no specific “hacking license” for landed properties, engaging licensed professionals is still highly advisable to avoid safety issues and legal liabilities.
Who Can Perform Hacking Works Legally?
In Singapore, not all renovation contractors are allowed to perform hacking works. You must engage:
- An HDB-licensed renovation contractor (for public housing)
- A BCA-registered contractor or professionally qualified firm (for structural works in private or landed properties)
These contractors understand the compliance process and are trained to carry out hacking safely and efficiently.
To verify if a contractor is licensed by HDB:
- Visit the HDB Directory of Renovation Contractors
- Search for the contractor’s name or license number
- Check their licensing status and approved scope of work
How to Apply for Hacking Approval (HDB)
Here is a simplified process for getting hacking approval in an HDB flat:
- Hire an HDB-licensed contractor
- Submit renovation permit application through the contractor
- Include proposed layout changes and hacking details
- Wait for HDB approval (usually 3–5 working days)
- Begin work only after written approval is granted
Contractors must also display the approved permit on-site throughout the renovation period.
Risks of Unauthorized Hacking
Unauthorized hacking works can have serious consequences:
- Structural Damage: Removing a load-bearing wall may weaken the building and pose safety risks.
- Fines and Penalties: HDB or MCST can impose financial penalties or order reinstatement of the original structure.
- Loss of Insurance: Home insurance may be voided if damage is caused by unapproved work.
- Renovation Delays: Authorities can halt ongoing renovations if work is found to be non-compliant.
To avoid such issues, always consult your contractor and confirm that proper licenses and permits are in place.
Tips for Homeowners
- Plan Early: Allow enough time to secure permits before scheduling your renovation.
- Get Detailed Quotations: Ensure your contractor includes permit application and compliance in their pricing.
- Communicate with Neighbors: Inform them in advance about noisy works to reduce complaints.
- Request Updates: Follow up with your contractor to ensure all approvals are secured.
- Keep Records: Retain copies of all approved plans and permits for future reference or resale.
Conclusion
Yes, a license or permit is definitely required for hacking works in Singapore, especially for HDB flats and certain private properties. While the term “hacking license” is more commonly used informally, what’s legally required is a renovation permit and adherence to the regulations set by HDB, MCST, or BCA.
Whether you’re planning to remove tiles, reconfigure layouts, or dismantle fittings, always engage a qualified professional who understands the compliance process. Doing so ensures that your renovation proceeds safely, legally, and without costly setbacks.
