What is HDB Renovation Permit?

There are renovation works that require written approval from HDB. You’ll need these permits before any renovation work can take place.

If you don’t get a permit before starting the renovation works, HDB will treat it as unauthorised and ask you to reinstate your flat to how it was originally. Certain precincts that have unique designs and special features have additional guidelines that you need to comply with.

For works that don’t require permits, you’ll still need to comply with the guidelines governing them or HDB will ask you to remove them and restore your flat to its original condition.


What Are the Works That Require HDB Renovation Permit

Floor finishes

Any work that requires tearing up the existing floor or raising it will require a permit. For example, if you intend to replace all the tiles in your kitchen, doing so would require removing the old flooring.

Apart from the need to obtain a permit, there are also guidelines to follow. One of these is that the new floor finish must not exceed 5cm. If you are raising it, the height between the floor and window must not be less than 1m.

Halls Renovations

Before you hack down any walls in your flat, be warned – the HDB requires that a permit is obtained before demolition works may commence. Similar requirements also apply to construction of arches and rounded corners to existing openings; they too require approval from the authorities. Changing internal wall finishes? You’ll need a permit for this as well so make sure not to compromise on structural integrity!


Relocations of Doors

If you’re thinking about moving a door to another part of your house, keep in mind that the doors are not compatible with concrete walls. So if hacking is involved, it will also need reinforcement from columns and other load-bearing structures.


Renovate Bathrooms/ Toilets

After 3 years, if you decide to change the flooring or wall finishes of your bathrooms and toilets, or extend your bathroom/ toilet. You will need a permit from HDB which may take up to 6 months depending on how complex it is for them to evaluate this plan.


Changing of Staircases

If you’re looking to customize your home with a custom staircase, it will take time and patience. Firstly, you must get permission from both the HDB (Housing Development Board) and BCA (Building Construction Authority). After that, hire an engineer who can create different designs for approval by BCA; then wait until they approve before handing in the design to HDB for their renovation permit. This is just one of many ways to personalize your own space!


Windows Works

HDB has strict guidelines for window replacements, which need to be approved by HDB and follow a set of guidelines. Windows that are casement windows must not exceed 50 cm wide or 70cm long. Sliding windows cannot go past 120cm in width but can reach up to 50 cm high as well as the length you want them at (as long as it does not surpass 150% of your original). When installing new grille designs for service yards and balconies, they have two options: rectangular grids with no more than 1-inch gaps between bars on each side;

rectangular grid spacing should range from 5 inches apart down to 2 ½ inch gap depending on how flat dwellers intend their balcony use!

Window safety is of paramount importance for HDB, as they want to make sure that no-one ever gets hurt in case a window falls.


Bathroom Renovation Works

You’re not allowed to replace or alter your bathroom walls and floors for the first three years of ownership unless you have a renovation permit. This is because waterproofing membranes are installed by HDB that need time to stabilize, so water leakage doesn’t occur in there. After 3+ years, if you want more tiles on the floor or another kind of material like drywall on wall surfaces then it’s possible!

Larger bathroom fixtures such as a shower screen, long bath, and spa pool require certain conditions to be met prior installation. Public Utilities Board licensed plumbers can advise you on what is possible or not.
