Renovating your new HDB flat is an exciting milestone, but it’s also one that comes with a unique set of rules.

For first-time homeowners in Singapore, understanding HDB renovation guidelines is crucial to avoid unnecessary delays, costly mistakes, or even penalties.

From what you can and cannot hack, to when noisy works are allowed, these regulations are designed to maintain safety, harmony, and structural integrity in public housing.

At Visionary Interior, we simplify this process by guiding our clients through approvals, timelines, and compliance every step of the way.

Thus, this guide will walk you through the essentials of what’s permitted, what’s not, and how to renovate with peace of mind.

Can I Renovate My HDB Flat?

Yes, but with limitations. The Housing & Development Board (HDB) permits a wide range of renovation works, but certain alterations are strictly prohibited.

A common myth is that you can knock down any wall in your flat, but structural walls are off-limits. Any works affecting the building’s structural integrity or shared facilities require prior approval or are outright disallowed.

Permitted renovations typically include:

• Repainting walls

• Installing new flooring (with approval)

• Replacing doors and non-structural partitions

• Custom carpentry

Prohibited works include:

• Hacking structural walls or columns

• Changing the external façade

• Shifting toilets or sewage systems

To stay on the safe side, always refer to the official HDB renovation guidelines for the latest updates and full list of dos and don’ts.

How Long Does a HDB Renovation Take?

One of the most frequently asked questions is: How long does a HDB renovation take?

For newly completed flats, HDB allows a maximum of three months from the date of the renovation permit to complete all works. For resale flats, this window is shortened to one month.

Here’s a rough breakdown of typical renovation timelines:

• Kitchen renovation: 2 to 4 weeks

• Bathroom upgrades: 1 to 2 weeks

• Tiling/flooring: 1 to 2 weeks

• Carpentry and installation: 3 to 5 weeks

Keep in mind that delays can occur due to permit approvals or unexpected site conditions. Hiring a renovation firm that is well-versed in HDB renovation guidelines can keep your project on track and within compliance.

Working Hours and Noise: What You Need to Know

Renovating in an HDB flat means being considerate of your neighbours. HDB has strict rules regarding working hours and renovation noise to minimise disturbance in residential areas.

HDB renovation guidelines working hours:

• General works: Mondays to Saturdays, 9am – 6pm

• No renovation work is allowed on Sundays and Public Holidays

HDB renovation noise rules:

• No noisy work (e.g. hacking, drilling) after 5pm

• No noisy work on Saturdays, Sundays, or Public Holidays

• All noisy work must be completed within three consecutive days

These rules are strictly enforced, and violations may lead to penalties or complaints. You can read more on the HDB renovation noise guidelines.

HDB Renovation Permit Fees and Approvals

Not all renovation works require a permit, but many do, especially those that affect the structure or plumbing systems. Understanding what needs approval (and what doesn’t) will help you plan better and avoid delays.

Works that typically require a permit:

• Hacking or removing walls

• Tiling works

• Repositioning sinks or toilets

• Replacing windows or grilles

Works that typically do not require a permit:

• Painting

• Installing built-in cabinets

• Furniture works

As for HDB renovation permit fees, there is no direct charge for submitting a renovation permit, but homeowners will need to pay a refundable renovation deposit to HDB. This ensures that all works are done in compliance, and the common property is not damaged.
