Introduction
Planning to renovate your HDB flat in Singapore? Before you start knocking down walls or replacing floors, you'll need to understand the crucial first step: getting an HDB renovation permit.
This official approval from the Housing & Development Board isn't just paperwork – it's your legal authorisation to make specific changes to your flat. Without it, you risk hefty fines and might even have to undo your renovations at your own expense.
Singapore's strict regulations are in place for good reasons. They protect the structural integrity of buildings, ensure resident safety, and maintain the quality of living in public housing estates. Moreover, since HDB flats are interconnected structures in high-density environments, improper renovations can affect your neighbours and potentially the entire building.
Therefore, understanding HDB renovation permits is not optional – it is essential for anyone planning to modify their flat. This comprehensive guide walks you through everything you need to know about HDB renovation permits in 2025, from application processes to costs and regulations.
What Is an HDB Renovation Permit?
An HDB renovation permit is an official document issued by Singapore's Housing & Development Board that legally authorises homeowners to carry out specific renovation works in their HDB flats.
Think of it as your golden ticket to start renovation works. The permit essentially confirms that your planned renovations comply with HDB's guidelines and regulations. Furthermore, it ensures that your proposed changes won't compromise the building's structure or safety systems.
Types of Works Requiring HDB Permits
Not all renovation works require a permit. However, many common renovations do need official approval, including:
- Structural alterations: Demolishing or altering walls, especially load-bearing ones
- Floor works: Replacing existing floor finishes (tiles, marble, parquet)
- Wall finishes: Replacing internal wall finishes up to ceiling height
- Doors and windows: Replacing main entrance doors on fire escape routes or repositioning internal doors
- Wet areas: Enlarging bathrooms or toilets (only allowed after the 3-year restriction period)
- Electrical works: Installing new 15a power points or 20a isolators
- Gas works: Relocating gas meters or installing certain gas appliances
Works That Don't Need Permits
On the other hand, some minor renovations can proceed without a permit, such as:
- Interior painting
- Laying floor finishes over existing ones using only adhesive
- Installing built-in furniture without structural alterations
- Minor electrical works, like installing light fixtures
- Simple plumbing works, like replacing sinks or taps
However, even these works must still follow HDB's technical guidelines. Additionally, many require licensed professionals, such as electricians or plumbers.
Why You Need a Permit (Legal & Safety)
Getting an HDB renovation permit isn't just about following rules – it's about ensuring safety and preventing costly mistakes. Moreover, there are serious consequences for non-compliance.
Legal Requirements and Compliance
The HDB renovation permit system is a fundamental part of Singapore's public housing governance. Consequently, it is not optional – it is required by law for applicable renovations.
Permits serve as an essential checkpoint to ensure your renovations meet Singapore's strict building codes. Furthermore, they verify that you are using approved methods and registered personnel for potentially hazardous modifications.
Serious Consequences of Non-Compliance
Skipping the permit process can result in severe penalties:
- Fines of up to S$5,000 upon conviction
- Mandatory removal of unauthorised renovations at your expense
- Suspension of any permits that may have been granted
- Potential difficulties in future dealings with HDB
Additionally, contractors involved may face demerit points, fines, or suspension from the Directory of Renovation Contractors.
Safety Concerns
Beyond legal compliance, permits protect everyone's safety. Unauthorized renovations might:
- Compromise the building's structural integrity
- Create fire hazards through improper electrical work
- Cause water leakage affecting neighbors
- Introduce safety hazards for residents
Therefore, the permit system isn't bureaucratic red tape – it's a critical safeguard for all residents.

How much will your HDB renovation permit cost? While official HDB sources don't publish a fixed fee schedule, we can provide guidance based on industry knowledge.

Remember that these fees represent only the direct administrative costs for permit processing. The total cost of ensuring a compliant renovation includes additional expenses.

How to Apply for HDB Renovation Permit Online
Applying for an HDB renovation permit is primarily done online through HDB's electronic services. Here's how the process works:
The HDB renovation permit application process follows several key steps. First, engage an HDB Registered Renovation Contractor from the Directory of Renovation Contractors (DRC). Then, prepare all necessary documentation, including scaled floor plans showing proposed changes. Your contractor will then submit the application through the HDB portal using their business account.
Step-by-Step Application Process
- Engage a contractor: Select and hire a contractor from HDB's Directory of Renovation Contractors (DRC)
- Prepare documentation: Work with your contractor to prepare floor plans and other required documents
- Contractor login: Your contractor logs into their business account on the HDB portal
- Application initiation: The contractor starts the "Application for Renovation Permit via Electronic Transaction" (APEX)
- Form completion: The contractor fills in details about your flat, your information, and proposed works
- Document upload: Required documents are uploaded, including signed Acknowledgement Forms and floor plans
- Fee payment: Any applicable fees are paid through the portal
- Submission: The completed application is submitted to HDB for review
For certain electrical works, a Licensed Electrical Worker (LEW) may need to submit a separate application.
Required Documentation
Your application must include:
- Scaled floor plans: At least two copies showing existing layout and proposed changes
- Acknowledgement Form: Signed by all registered flat owners
- Renovation proposal: Detailed list of specific renovations
- Contractor details: Information confirming your engagement of an HDB Registered Renovation Contractor

Additionally, plans should use specific color coding: RED for elements to be demolished, BLUE for new elements, and YELLOW for areas where a wall is demolished and rebuilt in the same location.
Approval Timeframes
How long will you wait for approval? Typically, HDB takes up to three weeks to process renovation permit applications. However, this timeframe varies based on:
- Complexity of works: Simple renovations may be approved in 3-7 days
- Completeness of application: Missing information will delay approval
- HDB workload: Processing times may increase during peak periods
For planning purposes, factor in at least 3-4 weeks from application to starting work.

Financing Your Renovation: HDB Renovation Loan & Alternatives
Wondering how to fund your renovation? Several financing options exist, each with different terms and benefits.
The HDB renovation loan is a government-supported option specifically for HDB flat renovations. It typically offers a maximum of S$30,000 or 6 times your average monthly income (whichever is lower) at competitive interest rates. Repayment terms usually range from 1-5 years, and eligibility requires Singapore citizenship or permanent residency.

Tips & Best Practices
Successful HDB renovations depend on careful planning and smart decision-making. Here are key tips to ensure a smooth process:
Selecting a Reliable Contractor
The right contractor makes all the difference in your renovation experience. Therefore:
- Verify DRC listing: Confirm the contractor is currently listed on HDB's Directory of Renovation Contractors
- Check experience: Review their portfolio, especially HDB projects similar to yours
- Get multiple quotes: Obtain detailed written quotations from at least three different contractors
- Review contracts thoroughly: Ensure the contract clearly states scope, materials, timelines, payment schedules, and warranties
- Verify insurance: Ask for proof of the contractor's insurance coverage
- Assess communication style: Choose someone responsive who understands your requirements
Remember that even with registered contractors, disputes can arise. Always attempt to resolve issues amicably first, then seek assistance from CASE or Small Claims Tribunals if needed.
Planning and Budgeting Effectively
Proper planning prevents poor performance:
- Define clear objectives: Identify your renovation goals and prioritize must-haves versus nice-to-haves
- Develop detailed scope: Create a comprehensive list of required works
- Budget realistically: Research typical costs and include a 10-20% contingency fund
- Secure financing early: Determine and arrange your funding source before proceeding
- Consider professional help: Decide if you need an interior designer or if a contractor alone suffices
- Create a realistic timeline: Understand all phases of the renovation process
Sample Renovation Timeline
A typical HDB renovation follows these phases:
- Pre-renovation planning (4-5 weeks): Defining scope, selecting contractors, signing contracts
- Permit application (3 weeks): Submission and approval process

- Demolition and hacking (1-2 weeks)
