Before buying or renting a home in Singapore, look up the surrounding streets in PUB’s published flood-prone area and hotspot lists. Check the exact road section or junction. Then compare it with the paths your household would use to reach the building, bus stop, school or car park.
The home’s floor level answers only part of the question. A high-floor unit can still depend on a low-lying driveway or basement access. For a ground-floor home, check the entrance and any outdoor area too. Ask the owner or estate manager about past incidents and the arrangements for residents during heavy rain. Find the current flood-prone area and hotspot lists on PUB’s website.
- Check the list dates and match the street segment or junction.
- Mark the entrance, car park ramp and regular walking routes on a map.
- Ask specific questions about previous incidents and estate arrangements.
- Use PUB’s alert channels for current conditions.

Check the address and the routes separately
Look up the street name, the nearest road junction and the driveway you would actually use. Some PUB entries refer to a stretch between two streets or to a particular slip road. Record the limits as shown. If one part of a road is listed, trace whether your own route uses that part.
| Place to check | Question for the household |
|---|---|
| Building entrance | Which access points would we use in heavy rain? |
| Basement car park or driveway | What has estate management arranged if access is affected? |
| Path to bus or MRT | Does the everyday route cross a listed junction or road segment? |
| School, childcare or eldercare route | Is there a practical way to reach the destination if part of the usual route is affected? |
| Ground-floor unit or private outdoor area | Has water previously reached any door, threshold or outdoor space? |
Use the lists as a starting point. If the street is absent, you can still ask about the building and the routes that matter to your household. If a nearby street is listed, establish which section it refers to before drawing conclusions about the unit.

Ask questions the owner or estate can answer
A broad question such as “Does it flood here?” can lead to an answer about a different entrance or an incident many years ago. Ask where water reached, when it happened and whether access was interrupted. Ask what changed afterwards and who informs residents if an entrance or car park is affected. For a condo, ask the managing agent which channels carry estate notices.
For example, imagine two homes near the same bus stop. One estate has a second pedestrian entrance, while the other household would normally use a driveway beside a listed junction. Compare the specific routes and ask whether the second entrance is available when residents need it. The same nearby location can have different effects on the two households’ routines.

Use current alerts for the day’s conditions
PUB’s published lists help with location research. Its Get Flood-Wise page links to real-time alert channels, including myENV for heavy rain and flood risk updates. Check current official advice when planning a journey in heavy rain. If an incident blocks your route, use an available safe route or wait for conditions to improve. See PUB’s flood alert channels and advice.

Frequently asked questions
Should I check the basement if the unit is on a high floor?
Yes, if you rely on a basement car park, drop-off area or entrance. Ask the estate manager about the specific route from the street to your block.
Can a dry-weather viewing help?
It can help you identify the paths and entrances you need to ask about. Use the estate’s records and current PUB information for questions about actual incidents and conditions.
What if planned works are mentioned?
Ask for the project name and responsible agency. Check its published information for the location and timing, and keep those details separate from what you observe at the property.
