Is this street flood-prone? Rain in many Nigerian cities is heavy, and drains do not always keep pace. A street that is fine in the dry season can be impassable after an hour of rain. You can learn which kind of street you are looking at in about five minutes, with three checks and one question.
The question for the neighbours
Do not ask the agent. Ask a shopkeeper, a gatekeeper or a neighbour:
- What happens on this street when it rains heavily?
- How deep does the water get, and how long does it stay?
- When did it last flood, and did it get into the houses?
People will tell you plainly, because they live with it. If different people give different answers, trust the worst of them.
Check one: the drainage
Look at the drains along the street. Are they open and clear, or blocked with waste and sand? Are they wide enough, and do they actually lead somewhere? A drain full of rubbish is a drain that will not work when you need it. Note any standing water on a dry day, which suggests poor flow.
Check two: levels
Compare the level of the road with the level of the compound and the building.
- Is the road higher than the compound? Then water tends to run in.
- Does the compound slope down to the gate, or away from it?
- Is the ground floor raised, and by how much?
- Is the street in a natural low point, or at the bottom of a slope?
A building that sits below its road is the one most at risk.
Check three: the building's own signs
A flat leaves a record of what has happened to it.
Stain lines
A horizontal mark on the wall or gate is often a past water level.
Damp and mould
Especially low on walls and in corners.
Peeling paint
Bubbling or flaking near the floor.
Warped wood
Door frames, skirting and cupboards that swell.
Fresh paint on the lowest floor
Ask why, and what it covers.
Raised thresholds and sandbags
Signs that residents expect water.
If you can, go after rain
A visit just after a heavy shower shows you the street as residents live it. Look at the road, the drains and the compound. Check whether you could get a vehicle in and out. Ask for photos from the last rainy season, from the landlord or neighbours.
Higher floors and other fixes
A higher floor protects your flat from water inside the building, but not access to the road, parked vehicles or power and services that rely on the ground floor. Check the pump, the meter and the generator, and where they sit. A flat with a dry floor but no way out is not much of an improvement.
What flooding does to the numbers
If you rent somewhere that floods, you may pay in repairs, lost belongings, damaged furniture, mould and travel. Compare areas with the real cost in mind. How to choose a Lagos neighbourhood includes flooding in its five tests, and the move-in cost calculator has a field for the extra costs of getting set up.
For buyers
If you are buying, ask about the property's flood history, the area's drainage plans and whether insurance is available and at what cost. A cheaper price may reflect a real risk. Read documents to check before you buy land in Lagos for the paperwork side.
Put it in your search
When you describe the home you want to Zedo, say so: "not in a flood-prone area". Then check each result yourself with the five minutes above, and ask the 12 questions before you pay rent.
A simple scorecard
After the three checks, give the street a score. This takes a minute and turns a feeling into a comparison.
| Check | Good sign | Warning sign |
|---|---|---|
| Drains | Open, clean, flowing and covered where needed | Blocked, full of waste or missing |
| Road level | Building sits above the road | Building sits below, with a ramp down |
| Marks | Clean walls and gate base | Water lines, peeling paint, mould smell |
| Neighbours | "It has never flooded here" | "It floods every year, we just wait" |
| Escape route | A dry way out on higher ground | One road that goes under water first |
Give one point for each good sign. Three or four points suggests a sound street. One or two suggests asking a lot more questions before you pay anything.
What to do if you must live in a flood-prone area
Sometimes a flood-prone area has the best commute or price. If you decide to take the risk, reduce it.
- 1Choose a higher floor, and not the ground floor.
- 2Raise your electrics, plugs and appliances off the floor.
- 3Keep important documents in sealed bags on a high shelf, with copies in the cloud.
- 4Know the way out and where you will go if the road floods.
- 5Ask the landlord who handles damage, and put the answer in the agreement.
Ask about contents insurance too, and read what it covers, because many policies exclude flood damage unless you add it.
Questions for the landlord
A landlord who knows the street will usually be honest if asked directly. Ask: has the compound flooded in the last five years? What was done afterwards? Is the drainage the landlord's responsibility or the community's? Do not accept "it was only once" without asking when, how high the water rose and what was damaged.
Put the answer in writing. If the flat floods after the landlord said it never had, a written statement helps you. It also supports a claim for your caution deposit if you have to move out early.
Use data where you can
Some cities publish flood risk maps or reports, and local news often covers the worst-hit areas after heavy rain. Search the street name together with the word "flood" and read what comes up. Local social media groups can add detail. Treat these as clues rather than facts, and confirm each with a neighbour.
Search for what you want
When you search on Zedo, say what matters. For example, "second-floor flat on a road that does not flood, with a borehole." A search that includes your real worries finds homes that fit, and saves viewings that go nowhere. Check the cost of each option with the move-in cost calculator.
A rainy-day routine
If you can, make one visit when it is raining or just after.
- 1Walk the street from the main road to the building.
- 2Watch where the water goes. Are the drains flowing, blocked or overflowing?
- 3Look at the gate and the compound. Is water standing or flowing in?
- 4Check the ground floor for damp, smell and marks.
- 5Take photos with the date, so you can compare with what the landlord says.
Ask the right people
Neighbours, shopkeepers, security guards and drivers who use the road know the history. Ask them: "When did it last flood, and how high did the water get?" Their answers are more honest than an advert. Ask the landlord for the same information, and compare.
What to do if you must rent there
If the home has many other strengths, you can reduce the risk: choose an upper floor, keep valuables and documents high, raise electrics and agree in writing who handles flood damage. Renting in Port Harcourt and Port Harcourt: GRA, Trans Amadi and choosing an area show how this plays out in a city of heavy rain.
