The 10-Minute Flood Check Every Lagos Home Buyer Should Do

The agent will show you the kitchen. Nobody will show you the gutter. Here is how to check a Lagos home for flood risk before your deposit leaves your account.

Every Lagos viewing follows the same script. The agent takes you in, walks you upstairs and points at the POP ceiling, telling you how luxurious the property is. He opens the kitchen cabinets. He taps the marble and says, “See the finishing.” You nod. You take pictures for your folks to help you decide.

Nobody walks you to the gutter.

And the gutter is where the real story of that house is written. Your flat can sit bone dry on the third floor while the junction outside turns into a small lagoon. Your car spends the night on the wrong side of the water. You paid for the house… but on that evening, the rain decided whether you could get home.

What happened on Saturday

On 7 November, Lagos State’s Commissioner for the Environment and Water Resources, Tokunbo Wahab, led inspections in Oregun, Surulere and Osborne Foreshore Estate in Ikoyi.

In Surulere, he said officials measured the distance between a development and a drainage channel after the ministry received a complaint. According to him, the works stayed clear of the channel’s right-of-way. In Ikoyi, he said a separate inspection found that the drainage structure under review did not encroach on the government’s drainage alignment.

Two clean results. Good news for those owners.

But look at how the Surulere check started. A complaint. Somebody on that street was watching the water closely enough to call the government. That is the kind of neighbour you want to talk to before you buy.

And the stakes are real. In the past two years, the same ministry has pulled down fences, shops and walls built on drainage setbacks in places like Lagos Island, Apapa and Alaba. Nobody budgets for that when they are paying for a house.

Wahab also said Lagos is working to improve flood control before the 2027 rains. That is the government’s job. Your job is smaller, and you can start it this week:

What happened on this street the last time it rained hard?

Step 1: Drive the road home

Do not just drive to the viewing. Drive the route you would actually use every day, from the main road to the gate.

Watch for three things:

Low points. Any dip in the road where water would naturally settle.
Drains that just… stop. A drain that ends in the middle of nowhere is sending its water somewhere. Usually onto the road.
The turn you cannot avoid. If there is only one way in and it floods, you are stuck. Simple.

If the estate has a second gate, ask whether residents can actually use it, and whether it opens onto a different road. A second gate that is always locked is a decoration.

Step 2: Ask the people who were there when it rained

The agent is paid when you sign. I am not saying he will lie to you. I am saying he was probably not standing at that junction at 9pm in July.

The security man was. So was the woman selling provisions outside the estate, and the neighbour who has lived on the street for six years.

Here is the trick. Do not ask, “Does this area flood?” You will hear, “No o, this place is fine.” Every time.

Ask questions that pull out a memory instead:

“The last time it rained heavily, could residents drive out that evening?”
“Did anybody have to move their car?”
“Which junction filled up first?”
“How long did it take for the water to go down?”

People remember specific evenings. They forget general opinions. You will get far more honest detail this way.

Step 3: Come back after the rain

If you can, return after a heavy downpour, once the roads are safe. Follow the exact route you took on your first visit. Same gate, same junction, same turns.

Take a video while you drive. Then compare.

Buying from abroad? This step matters even more for you. Send someone you trust, not the agent, after a proper downpour. Ask for one unedited video from the main road all the way to the gate, with the date visible on their phone. A two-minute video can save you years of regret.

Step 4: Go downstairs, even if you are buying upstairs

A fourth-floor flat still depends on what happens at ground level.

Walk to the entrance of the car park. Then ask the building manager three questions:

Where are the lift equipment, the water pumps and the generator or backup power?
Has water ever entered the car park, the lift pit or the ground-floor units?
If yes, what was repaired, and has it happened again since?

Think about it. If the generator house floods, your fourth-floor light goes with it. If the lift pit floods, you are climbing stairs with your shopping.

Inside a house or a ground-floor flat, look low:

Freshly painted patches near the skirting boards
Door frames that look swollen or will not close properly
Stains running along the bottom of the walls

These signs can come from several things, so do not panic and do not guess. If you see them, get an independent building inspector to trace the source and tell you what a repair would really involve. A fresh coat of paint in a resale flat can be innocent. You just want to know why that one patch is so new.

Step 5: Put the survey next to the building plans

This is the boring part. It is also the part that protects your money.

Ask the seller for:

The survey plan
The approved building drawings

Then hire a registered surveyor to check the boundaries on the ground and show you exactly where the plot sits in relation to any nearby drainage corridor.

Buying land to build on? Ask one extra question: once the required setbacks are accounted for, how much room is actually left for the house, the parking and the access road? Some plots look big on paper and shrink fast in real life.

One detail worth knowing: Lagos State’s planning table lists drainage clearance from the Office of Drainage Services for applications less than 10 metres from an existing drain or gorge. That tells you when the table calls for clearance. It does not tell you everything that applies to your specific plot. Your surveyor or planning professional should confirm that.

Finally, let your lawyer verify the seller’s title and the relevant approvals before you pay a kobo.
