HDB gate replacement rules
Before you replace your HDB main gate, know two things: you do not need a permit, but the new gate must keep the original size and layout. HDB's renovation guidelines for building works say the gate width, the number of panels and the swing must be the same as originally provided by HDB. The gate swing must also not obstruct public escape.
In practice, you can still choose a new material, finish, pattern and lock. A two-panel gate stays a two-panel gate, with the same width and the same swing.
HDB also sets clearances for when the gate is open, based on where your flat sits:
| Unit position | Clearance to keep |
|---|---|
| Along the common corridor, gate opening perpendicular to the parapet | At least 0.6m from the gate to the corridor parapet wall |
| Next to a staircase | Equal to the staircase width, measured from the gate edge at all opening angles to the staircase railing |
Fire door and corridor safety
Your gate and your main door do different jobs. HDB's gate and door guide describes the gate as a safety barrier and the main entrance door as a fire safety barrier, and asks you to inspect both regularly. All fire-rated entrance doors have a door closer, a self-closing safety device that must not be removed. If the door also needs changing, see the fire-rated main door comparison.
The common corridor outside your flat is a shared escape route. The Singapore Civil Defence Force (SCDF) says that where shoe racks, foldable clothing racks or potted plants are allowed along the common corridor, a minimum clear escape passage of 1.2m must be maintained (SCDF fire safety guidelines for residential estates). Town Councils and Management Corporations are empowered to enact by-laws to control and manage the use of common areas, so ask your Town Council what you may keep outside your gate.
Locks and repairs instead of replacing
A gate that sticks or will not lock may only need a repair. HDB's gate and door guide says gate bolts that cannot slot or retract properly come from wear of the bolt or rubbish in the bolt hole. The fix it gives is to repair or replace the flush bolt, clear the hole, lubricate the bolt and remove dirt.
If the lock itself is the problem, start with the gate lock replacement guide. For the main door, compare companies that list door lock replacement.

Published door and lock rates
For the most common unit (per job), the lowest published door and lock rates from 4 companies run from S$50 to S$120 per job (middle rate S$60), for one door or lock. The middle figure is a real published rate, not an average. Each figure is one company's own advertised rate with its conditions, not a quote.

In this table, 5 companies publish a door and lock line, each rate shown as printed. Of these, 4 price it per job: their published rates run from S$50 to S$120 per job, and the two middle rates are both S$60 per job. The fifth lists digital lock and locksmith services from S$80, printed without a unit. The rates are printed for one door or lock, so check what each price covers. One line, "Gate and door installation", starts from S$120 per job; ask that company what the job includes.
Choosing a gate
Within those limits, the choice is about how the gate looks, locks and works day to day. Check these points with each supplier:
- Material and finish. Ask what the gate is made of and how to care for the finish.
- Lock type. Choose a key or digital lock, and ask whether it comes with the gate or is priced separately.
- Mail slot. If post comes to your door, ask for a slot or letter box that does not stick out into the corridor.
- Mesh for privacy. Ask whether mesh or a backing panel can be added, and how it changes light and airflow.
- Lead time. Ask how long making and fitting take.
- Removal of the old gate. Ask whether taking down and disposing of the old gate is in the quote.
- Fit to the rules. Ask the supplier to confirm in writing that the width, number of panels and swing match the original.
Ask for these items on each quote so you can compare them line by line.

If you only want the gate to look fresh, painting may be enough. HDB's building works guidelines say painting the external side of the main door or metal grille gate needs no permit. Replacing a main entrance door that opens onto a passageway is different: it needs a permit, and the door and frame must be half-hour fire-rated, with a self-closing device and an accreditor's label.
If you plan a new gate and door, treat them as two jobs with different rules. The HDB renovation permit guide explains how permits work, and the windows and doors questions page covers other door queries.
Questions
Can I change my HDB gate to a different design?
Yes, as long as the size and layout stay the same. HDB says the width, number of panels and swing must be the same as originally provided. Within those limits you can choose a different design, material, finish and lock. Ask the supplier to confirm all three points before you order.
Can my new gate open outwards into the corridor?
Only if your original gate already opened outwards. HDB says the swing must be the same as originally provided and must not obstruct public escape, so you cannot change it to free up space inside. Corridor units also keep at least 0.6m from the gate to the parapet wall when it opens perpendicular to the parapet.
Will the old gate be taken away?
Only if removal is part of your quote. Ask each supplier whether taking down and disposing of the old gate are included, and get the answer in writing. If not, ask who will remove it and when, so it does not sit in the corridor.
How long does it take to make and fit a new gate?
Your supplier sets the timing, so ask for the lead time before you order. Ask how long making the gate takes, how long fitting takes on the day and whether the old gate stays up until the new one is ready. Plan for someone to be at home to let the installer in.
Should the gate and door be replaced together?
No, you do not have to replace them together. Under HDB's rules, replacing the metal gate needs no permit, while replacing a main entrance door that opens onto a passageway does. Doing both at once can make matching finishes simpler and mean one visit instead of two, so ask whether the supplier handles both.
What should I check when the new gate is fitted?
Check that the gate swings smoothly, the lock lines up and nothing sticks out into the corridor. Open and close it fully a few times and test any flush bolts. Confirm the swing matches your original gate, as HDB requires, and that the clearance to the parapet wall or staircase railing is kept.
