How to check flood risk before buying a home in Malaysia
There is no public government portal in Malaysia where you can type an address and get its flood risk. So we built the check into the listings themselves. We have assessed 19,855 properties across 171 areas, and 39% of them sit in a moderate or high flood-risk zone.
This page explains how to check any Malaysian address yourself, what our data shows, and exactly where the numbers come from.
The short answer: how to check a specific address
- Open the listing or area page on MyRumahBaru. Flood risk sits next to the price, with the recorded flood history for that location.
- Check the terrain yourself: how close is the nearest river or monsoon drain, and does the unit sit low relative to the road?
- Search the neighbourhood name together with "banjir" to find past monsoon reports.
- Ask the building management or neighbours directly whether it has flooded, and when.
- For high-rise, ask specifically about the basement car park and lift lobby — the unit can be dry while the car park floods.
Flood risk across 19,855 assessed Malaysian properties
We hold flood assessments for 19,855 of the 19,986 properties currently listed on MyRumahBaru. Of those, 12,187 sit in a low flood-risk zone, 6,881 in a moderate zone and 787 in a high zone. That puts 39% in a moderate or high flood-risk zone.
These are shares of properties listed on MyRumahBaru, not of all homes in Malaysia. They describe our inventory, which skews towards urban and suburban developments.
The table below covers the 11 states where we hold enough assessments to report a reliable figure. State rows will not add up to the national total: states with too few assessed listings are left out, and a small number of listings sit in areas our gazetteer cannot resolve to a state.
| State | Listings assessed | Low | Moderate | High | Moderate or high |
|---|---|---|---|---|---|
| Selangor | 7,165 | 4,380 | 2,450 | 335 | 39% |
| Kuala Lumpur | 5,304 | 3,576 | 1,493 | 235 | 33% |
| Johor | 2,873 | 1,924 | 924 | 25 | 33% |
| Pulau Pinang | 2,106 | 894 | 1,135 | 77 | 58% |
| Sarawak | 342 | 173 | 123 | 46 | 49% |
| Melaka | 191 | 75 | 113 | 3 | 61% |
| Perak | 142 | 86 | 53 | 3 | 39% |
| Negeri Sembilan | 123 | 105 | 16 | 2 | 15% |
| Sabah | 122 | 71 | 50 | 1 | 42% |
| Terengganu | 104 | 55 | 49 | 0 | 47% |
| Pahang | 88 | 42 | 45 | 1 | 52% |
Malaysian areas with the highest share of elevated flood risk
Ranked by the share of assessed listings sitting in a moderate or high flood-risk zone. A high share does not mean every home in that area floods — it means the terrain and river proximity put a large portion of them in an elevated-risk band.
| Area | State | Listings assessed | In a moderate or high flood-risk zone |
|---|---|---|---|
| Bandar Gamuda Cove | Selangor | 85 | 85 (100%) |
| Sibu | Sarawak | 66 | 66 (100%) |
| Bandar Bayan Baru | Pulau Pinang | 34 | 34 (100%) |
| Taman Danau Desa | Kuala Lumpur | 30 | 30 (100%) |
| Taman Sri Bayan | Pulau Pinang | 28 | 28 (100%) |
| Eco Sanctuary | Selangor | 27 | 27 (100%) |
| Taman United | Kuala Lumpur | 30 | 29 (97%) |
| Taman Len Seng | Kuala Lumpur | 28 | 27 (96%) |
| Bukit Rimau | Selangor | 26 | 25 (96%) |
| SS16 | Selangor | 27 | 24 (89%) |
| I-City | Selangor | 25 | 22 (88%) |
| Bandar Bukit Raja | Selangor | 32 | 28 (88%) |
Ranked by the share of assessed MyRumahBaru listings in each area that sit in a moderate or high flood-risk zone. Areas with too few assessed listings to describe reliably are excluded.
Where this data comes from, and what it does not mean
Flood risk is modelled per property from Open-Meteo global flood river-discharge data combined with terrain elevation at the property’s exact coordinates. It reflects the recorded flood behaviour and topography around that location.
It is a risk indicator, not a prediction and not a guarantee. A low-risk rating does not mean a property cannot flood, and a high-risk rating does not mean it has flooded. Local drainage, the age of the development and recent mitigation works all matter and are not captured in the model.
Malaysia’s Department of Irrigation and Drainage (JPS) produces flood hazard maps for major river basins and runs real-time river-level monitoring. Those are built for planners and emergency response rather than for someone checking one address, and a portal letting buyers check flood-prone areas, announced in 2024, has not launched. That gap is why we publish this.
What to look for when you view
- Visit on a rainy day if you can. Heavy rain shows you how the roads, drains and car park cope. Standing water that does not clear is a bad sign.
- For landed homes, ask whether the floor has been raised, and look for water marks on perimeter walls or the ground floor.
- Check where the electrical points and the distribution board sit. Raised wiring is a sign the area has a history.
- Look at the neighbours’ ground floors too, not just the unit you are viewing.
Questions to ask the agent or seller
- Has this unit or this block ever flooded? When was the last time?
- Is the area marked as a flood-prone zone by JPS or the local council?
- Does the house insurance cover flood, and is there an extra premium for it?
- What did the management or owner do after the last flood?
A note on insurance
Standard fire insurance in Malaysia usually does not cover flood on its own. You often need to add flood as an extra to a houseowner policy, and the premium can be higher in known flood areas. If a place has flooded before, factor that cost in.

How do I check if a specific address in Malaysia floods?
There is no public government portal for checking one address. On MyRumahBaru, flood risk is shown on the listing and area pages themselves, modelled from Open-Meteo flood river-discharge data and terrain elevation at the property’s coordinates. We have assessed 19,855 properties across 171 areas this way. Alongside that, search the neighbourhood name with "banjir" for past reports, and ask the building management directly.
What share of Malaysian properties are in a flood-risk zone?
Across the 19,855 properties MyRumahBaru has assessed, 39% sit in a moderate or high flood-risk zone: 6,881 moderate and 787 high, against 12,187 low. This describes properties listed on MyRumahBaru rather than all homes in Malaysia.
Which areas in Malaysia flood the most?
Flooding is most common on the east coast states like Kelantan, Terengganu and Pahang during the northeast monsoon, and in low-lying parts of the Klang Valley after heavy downpours. Risk depends a lot on the exact spot, so always check the specific neighbourhood rather than the whole state.
When is the flood season in Malaysia?
The northeast monsoon brings the heaviest rain to the east coast from around November to March. Other areas can flood during inter-monsoon periods or after a single intense storm, especially flash floods in built-up city areas.
Does flooding affect a property’s value?
Yes. A home with a flood history is harder to sell and usually fetches a lower price, because buyers worry about repeat damage and higher insurance. It can also mean ongoing repair and cleaning costs every monsoon.
Does home insurance in Malaysia cover flood?
Not by default. Standard fire insurance usually excludes flood. You typically need to add flood cover to a houseowner policy, and the premium can be higher in flood-prone areas. Always confirm the exact terms with your insurer.
Is there a government flood-risk portal in Malaysia?
Not one that lets a buyer check a single address. JPS publishes flood hazard maps for major river basins and runs real-time river-level monitoring, both aimed at planners and emergency response. A portal for buyers to check flood-prone areas was announced in 2024 but has not launched.
