Renovating an HDB flat in Singapore is an exciting but highly regulated process. While many homeowners want to refresh their living space with modern designs and personalized touches, there are strict rules in place to ensure safety, maintain structural integrity, and minimize disturbances to neighbors. If you’re planning a home makeover, understanding these guidelines can save you from unnecessary delays, fines, or even having to undo completed work.
One of the most important requirements is hiring an HDB registered contractor in Singapore. These professionals are approved to carry out renovations in public housing and are familiar with the dos and don’ts of the process. But beyond choosing the right contractor, there are several key regulations every homeowner should know before starting their renovation journey.
1. Getting Approval for Your HDB Renovation
Not all renovations require approval, but many do. If you plan on making major changes, such as hacking walls or changing your flooring, you must first seek approval from HDB. Unauthorized work can result in penalties and costly rectifications.
Renovations That Require Approval
- Hacking and demolishing walls – Structural integrity is a key concern, and only certain walls can be removed.
- Replacing floor finishes – Different flooring materials have specific requirements to prevent water leakage or noise issues.
- Rewiring electrical systems – All electrical work must comply with the Energy Market Authority (EMA) regulations.
- Plumbing modifications – Any changes to water pipes and sanitary systems must be approved.
- Window replacements – There are specific rules for the types of windows and grilles allowed.
For minor renovations like painting or installing built-in carpentry, approval is generally not required. However, it’s always best to check with HDB if you’re unsure.
2. Understanding the HDB Renovation Timing Rules
To minimize inconvenience to neighbors, HDB enforces strict renovation hours.
- Renovation work is only allowed Monday to Saturday, from 9:00 AM to 6:00 PM.
- No noisy work, such as drilling and hacking, is allowed before 9:00 AM and after 5:00 PM.
- No renovation work is permitted on Sundays and public holidays.
- If you are carrying out noisy works like demolition or drilling, it should be completed within three days.
Failing to comply with these timing rules can result in complaints from neighbors and even enforcement actions from HDB.
3. Wall Hacking and Structural Modifications
One of the most common renovation requests is hacking walls to create an open-concept layout. However, HDB has strict regulations regarding this, as improper modifications can compromise the building’s structural integrity.
- You cannot remove load-bearing walls or structural columns.
- Only non-structural walls can be hacked, and approval is needed before starting work.
- If you want to combine two rooms or expand your living space, you must get approval from HDB before proceeding.
4. Flooring and Waterproofing Guidelines
When changing flooring, there are specific guidelines to follow to prevent issues like water leakage and excessive noise transmission.
- All wet areas like kitchens and bathrooms must have waterproofing membranes to prevent leakage.
- New flooring must be at least two weeks old before waterproofing tests can be conducted.
- Hacking of existing floor tiles is only allowed for flats that are at least three years old.
- Vinyl and laminate flooring must have adequate soundproofing to minimize disturbances to lower-floor neighbors.
5. Electrical and Plumbing Regulations
Electrical and plumbing work are two critical aspects of an HDB renovation that require professional handling.
- Only licensed electricians can carry out electrical work to prevent fire hazards.
- Plumbing work must be done by HDB-approved plumbers to ensure compliance with safety standards.
- Gas pipes cannot be tampered with or repositioned without approval from City Energy.
- Concealing water pipes inside walls or floors is not allowed.
6. Window and Gate Replacement Rules
Changing windows may seem like a minor upgrade, but there are guidelines to follow.
- The new windows must not protrude beyond the building’s façade.
- Only HDB-approved window designs can be installed.
- For safety reasons, casement windows on high floors must have restrictors to prevent them from opening too widely.
- If your flat is under a window safety recall, you may be required to upgrade to compliant designs.
For main gates, ensure that the new design does not exceed the allowed width and height specifications set by HDB.
7. Permissible Built-In Features
While homeowners love customizing their interiors, there are restrictions on built-in furniture and fixtures.
- Built-in wardrobes, cabinets, and feature walls must be made of non-combustible materials.
- False ceilings and partition walls should not obstruct fire sprinkler systems.
- Air-conditioning units must be installed following HDB’s air-con installation guidelines.
8. Debris Removal and Clean-Up
Renovation debris must be disposed of properly, and contractors are required to clear all construction waste daily.
- No debris should be placed in common corridors, lifts, or staircases.
- Some towns require homeowners to arrange for bulk waste collection with town councils.
- Failing to dispose of renovation waste properly can result in fines.
9. Engaging the Right Professionals for Your Renovation
To avoid potential issues, it’s essential to hire professionals familiar with HDB regulations.
- An HDB-approved contractor ensures that all work follows guidelines and gets necessary approvals.
- Licensed electricians and plumbers help ensure your renovation meets safety standards.
- Interior designers who specialize in HDB flats can guide you through compliant design choices.
