What Is A HDB Renovation Permit?

The Housing and Development Board (HDB) is a public housing authority in Singapore formed to provide affordable housing to the people of Singapore. The HDB is responsible for planning, designing, constructing, and managing public housing in Singapore. The HDB offers several services to help you renovate your flat or house.

If you live in a Housing and Development Board (HDB) flat, you must obtain a permit before carrying out any renovation or alteration works. The HDB Renovation Permit is required for all tasks related to hacking, electrical, plumbing, and gas, as well as for any structural changes to the flat.

Remember that you’ll need to adhere to HDB’s guidelines for renovations, which include ensuring that the work does not pose a fire hazard, cause structural damage, or disturb the peace of your neighbours.

However, this time frame can vary depending on several factors, such as the complexity of the project and the number of permit applications HDB is currently processing. If you’re planning a major renovation project, submitting your application as early as possible is always best to avoid any delays.

If the works are approved, HDB will issue a permit valid for 3 months.

However, the deadline depends on your needs, and if you need to resale the BTO flat, the permit will be valid for one month only. Always observe the time validity to avoid penalties.

What Renovation Works Require A HDB Renovation Permit?


Hacking of Walls

If you are hacking the wall of your house, it will be considered a major renovation and therefore requires you to get a renovation permit. This is because there might be some structural changes that need to be made by an expert, which would impact your house’s safety.

For safety, HDB suggests you start demolishing the walls from the ceiling to avoid damage.

Building An Extension On Your Balcony

You can use the space on your balcony to extend your home. But if you wish to build an extension on the balcony, you will need an HDB Permit. The total floor area of the extension should not exceed 60% of the total floor area of the original unit.

Replacing Your Flooring/Tiling

If you are replacing your flooring or tiling, you must apply for any permits from the HDB. These changes affect the structure of your building. Your flat is part of the structure of the flat and must be replaced professionally.

Replacing Doors or Windows

You need to ensure that whatever you’re replacing matches the rest of the building’s design. You should also ensure that your new door or window is energy efficient to not cost you more money in electricity bills. The windows should be 50 cm by 50 or 70 by 120 and match the other BTO flat windows.

The guidelines are strict to avoid any injuries. Imagine if a window or a door breaks and ends up hurting someone.

Bathroom Works

You may want to change your bathrooms by including a toilet bowl, shower, and basin. For the first 3 years of owning your BTO flat, no replacement should be done in the bathroom to avoid water leakage since the waterproofing could be new.

If you wish to replace your old toilet with one that has different specifications from the original one, you will need an alteration permit from us before starting the project.

Plumbing Works

The most common type of Renovation undertaken by HDB owners is plumbing works. No permit is required when changing the sinks, tubs, and other fixtures, only when piping underneath the flooring.

When you have an HDB Permit, you can get certain plumbing works done yourself; however, all heavy water and sanitary tasks are done by Public Utilities Board (PUB) Licensed Plumber.

Changing Stairs

If you reside in an HDB flat, you may be able to change the staircase. The first thing you need to do is to check with the HDB if they allow such a change. It will depend on the structural stability of the staircase and whether any structural changes are required or recommended.

The design of your staircase should be drawn up by an architect or a registered building designer (RBD). You can find a list of RBDs on the Building & Construction Authority’s website.

Electrical Work

When you get an HDB permit for electrical work, you need to make sure that you know the limits of what you can do on your own and what needs to be contracted out.

Very minimal electrical activity is allowed, but we found one that is air conditioner installation, and we found only a BCA-trained installer can do the task.



How long do the renovations take as per the permit?

> Renovations might take 3 months and below. All this depends on the type of Renovation you requested.

What happens when I do renovations without a permit?

> You will be requested to cease the renovations until you attain a renovation permit. Further charges might occur since you might be prosecuted.

Why was my HDB renovation denied?

> HDB might deny your HDB renovation permit if they affect the safety of others, pose a fire hazard, or are a nuisance to the public.

Apply For Your HDB Renovation Permit Early

It’s best to plan early with your interior designer and apply for the HDB renovation permit early.
