Renovation Permit in Singapore: When You Need One

What Is a Renovation Permit

A renovation permit is an official approval required before certain types of renovation work can be carried out in your home. In Singapore, the permit system exists to ensure that renovations do not compromise building safety, structural integrity, or the living conditions of neighbouring residents.

The permit requirements differ depending on whether you live in an HDB flat, a condominium, or a landed property. Each property type is governed by different authorities and regulations. This guide explains when a permit is needed, who issues it, and how the application process works for each property type.

Understanding permit requirements early in the planning process prevents delays, avoids enforcement action, and ensures your renovation proceeds smoothly from start to finish.

HDB Renovation Permits

For HDB flat owners, renovation permits are managed through the HDB Infoweb and are applied for by your appointed renovation contractor. Not all works require a permit — the requirement depends on the nature and scope of the renovation.

Works that require an HDB renovation permit:

• Hacking of wall tiles, floor tiles, or screeding
• Demolition of any wall, including non-load-bearing partitions
• Erection of new walls or partitions
• Relocation of plumbing or sanitary fixtures
• Changes to the main entrance door or gate

Works that do not require a permit (but must use a registered contractor):

• Painting or repainting of interior surfaces
• Installation of flooring as an overlay (without hacking existing tiles)
• Application of wallpaper or wall coverings
• Installation of built-in carpentry
• Replacement of sanitary fittings in the same position
• Electrical works (power points, lighting, switches)
• Installation of curtain tracks and window treatments

The permit application is submitted online by your HDB-registered renovation contractor. Processing typically takes three to five working days. No work on permit-required items should begin until the permit is issued.

Important: even works that do not need a permit must be carried out by a contractor listed in HDB’s Directory of Renovation Contractors. Using an unregistered contractor is a violation of HDB’s terms.

Condominium Renovation Approvals

Condominium owners must obtain approval from the Management Corporation Strata Title (MCST) before starting any renovation. This is a separate process from any government permits and is specific to each development.

The MCST approval process typically requires:

• A completed renovation application form
• A scope of works describing each proposed activity
• Layout plans if walls are being moved or spaces reconfigured
• Contractor details, including insurance coverage
• A renovation deposit, usually refundable upon satisfactory completion

The MCST reviews the application against the development’s bylaws and may request modifications before granting approval. The timeline varies but typically takes one to two weeks.

In addition to MCST approval, certain works in condominiums also require BCA permits — specifically, any works that affect the structural elements of the building. If your renovation involves removing walls, creating new openings, or adding significant loads, a Professional Engineer must be engaged to submit plans to BCA.

Landed Property Permits

Owners of landed properties — including terrace houses, semi-detached homes, bungalows, and shophouses — face a different regulatory landscape. The primary authority is the Urban Redevelopment Authority (URA), with the Building and Construction Authority (BCA) overseeing structural and building safety matters.

Works requiring planning permission from URA:

• Additions and alterations that change the building footprint or gross floor area
• Changes to the building facade or external appearance
• Construction of new structures (car porches, extensions, swimming pools)
• Works to conservation shophouses (subject to URA’s conservation guidelines)

Works requiring a building permit from BCA:

• Structural alterations to the building
• Additions that constitute new building works
• Any works that affect fire safety provisions

Works that generally do not require permits:

• Interior repainting and redecorating
• Replacing flooring materials within the existing structure
• Installing wallcoverings, curtains, and soft furnishings
• Kitchen and bathroom refurbishment (without structural changes)
• Built-in carpentry and cabinetry

For landed properties, the permit process can be more complex and time-consuming than for flats or condos, particularly if planning permission is required. Engage an architect early in the process to navigate URA’s requirements efficiently.

When to Use a Professional Engineer

A Professional Engineer (PE) is required whenever your renovation involves structural works, regardless of property type. The PE’s role is to assess the structural implications of the proposed changes and certify that they can be carried out safely.

Common situations that require a PE:

• Removing or modifying walls to determine whether they are load-bearing
• Creating new openings in walls (such as pass-through windows between kitchen and dining)
• Installing heavy finishes or features that add significant load to the floor slab
• Any works that require BCA approval

The PE will produce engineering drawings and calculations that form part of the permit application. Their fees vary depending on the complexity of the work but are a necessary investment in safety and compliance.

The Permit Application Process Step by Step

While the exact process varies by property type, the general workflow for obtaining a renovation permit in Singapore follows a consistent pattern.

Step 1: Engage a registered contractor. For HDB flats, the contractor must be listed on HDB’s Directory of Renovation Contractors. For condos, the MCST may have its own list of approved contractors, or it may accept any licensed firm with adequate insurance.

Step 2: Finalise your renovation scope. Work with your contractor and, if applicable, your interior designer to finalise all proposed works. Be as specific as possible — vague descriptions can delay approval.

Step 3: Engage professionals where required. If structural works are involved, appoint a Professional Engineer. If the project involves planning permission for a landed property, engage a qualified architect.

Step 4: Submit the application. Your contractor submits the renovation application to the relevant authority — HDB for public housing, the MCST for condominiums, or URA and BCA for landed properties. Include all required documents, drawings, and deposits.

Step 5: Await approval. Processing times vary from a few working days for straightforward HDB applications to several weeks for complex landed property submissions. Do not commence any permit-required works during this period.

Step 6: Begin works. Once approval is received, renovation can proceed according to the approved scope, permitted hours, and conditions specified in the permit.

Keeping detailed records of your permit application, approval documents, and any correspondence with authorities is advisable. These records may be needed if queries arise during or after the renovation.

Renovation Works That Avoid Permit Requirements

Many impactful renovation activities do not require permits, making them faster, simpler, and more affordable to execute. These works can dramatically transform the look and feel of your home without the administrative overhead of the permit process.

Renovation Activity	Permit Needed	Typical Timeline
Vinyl flooring overlay	No	1 to 3 days
Wallpaper installation	No	1 to 2 days
Built-in carpentry	No	3 to 7 days
Painting	No	2 to 4 days
Curtain and blind installation	No	1 day
Tile hacking and replacement	Yes (HDB)	5 to 10 days
Wall demolition	Yes (HDB, BCA)	Varies

For homeowners who want to refresh their living space with minimal disruption, focusing on permit-free activities is a smart approach. Installing new wallcoverings, overlaying existing floors with luxury vinyl, and updating window treatments can achieve a dramatic transformation in just a few days.
