If you’ve been on social media in the last few weeks, you’ve probably seen the videos: cars floating down the Lagos-Oshodi Expressway, families being ferried out of Agungi in canoes, and shopkeepers in Amukoko wading knee-deep through their own stores. Late June 2026 brought some of the heaviest rainfall Lagos has seen in years, and the flooding wasn’t limited to the “usual suspects” on the Island. Streets in Gbagada, Chevron, Agungi, Ajiran, Egbeda, Ikola, Shomolu, Oshodi, Surulere, Itire, Lawson and Ikorodu all turned into rivers as hours of rain overwhelmed the drainage system. What has really unsettled residents is that flooding is no longer confined to the traditionally vulnerable coastal parts of Lagos Island — mainland communities that rarely flooded in the past are now increasingly affected.
For anyone planning to buy, build, or rent property in Lagos this year, this isn’t just a news story — it’s due-diligence information. At Planwell Homes, we work with clients across the city, and we’ve put together this guide to help you avoid buying into a flood zone.
Why This Year Is Different
Federal agencies have flagged July through September as the period of greatest flood risk for Lagos in 2026, meaning the heavy rain seen in late June could just be an early warning of what’s coming during the peak of the season. Nigeria’s Meteorological Agency had already forecast above-normal rainfall for Lagos this year, with a delayed end to the rains. In plain terms: this is shaping up to be one of the wetter years on record, and property buyers need to factor that into their decisions now — not after signing an offer letter.
High-Risk Areas to Watch
Based on assessments from the Nigerian Hydrological Services Agency (NIHSA), NEMA and the Lagos State Ministry of Environment, a few patterns stand out:
- Lekki Phase 1 & 2 — rapid construction without matching drainage infrastructure means even a short downpour can turn streets into rivers.
- Ajah, especially around Addo Road — inner streets here have seen water enter living rooms during past rainy seasons.
- Victoria Island backstreets (around Ahmadu Bello Way) — prone to tidal surges, where high lagoon levels push water back into the streets.
- Agungi, Ajiran, and Ikota — the state government itself has acknowledged illegal structures blocking canals here and has ordered their removal.
- Ikorodu and Isheri — vulnerable to riverine flooding linked to water releases from the Oyan Dam.
- Older mainland hubs like Surulere, Mushin, Oshodi and Egbeda — flash floods here are usually tied to ageing or blocked drainage rather than the ocean.
- Badagry, Epe and Alimosho — flagged by NEMA as flash flood zones for the current season.
If a property you’re considering sits in or near any of these areas, that alone shouldn’t rule it out — but it should raise your level of scrutiny.
Practical Steps Before You Buy
1. Visit during or right after heavy rain. Photos taken on a dry, sunny day tell you nothing about drainage. If you can, inspect the property (or ask your agent to send you a video) during or immediately after a downpour. Standing water that takes hours to clear is a red flag.
2. Check for “watermarks” and structural staining. Look at the base of walls, fences and gates for discoloration or mold lines — a telltale sign of previous flooding, even if the seller doesn’t mention it.
3. Assess the drainage around the property, not just inside it. A well-built house can still flood if the surrounding canal or gutter is blocked or poorly maintained. Walk the street. Are the drains clear? Do neighbors have sandbags or raised entrances — a sign they’ve dealt with this before?
4. Ask about elevation relative to the road and nearby canals. Properties built at road level or below are far more exposed than those with a raised foundation. This matters even more in reclaimed land areas around Lekki and the Lagos-Calabar Coastal corridor, where rapid development hasn’t always been matched by proper drainage planning.
5. Talk to long-term residents, not just the agent or seller. Neighbors who’ve lived on the street for years will tell you honestly whether “that one time” was a one-off or an annual event.
6. Review government flood advisories before committing. NIHSA’s Annual Flood Outlook and Lagos State Ministry of Environment advisories are published every year and name specific high-risk streets and LCDAs. It takes ten minutes to check whether your target property falls within a flagged zone.
7. Factor in insurance and resale value. Properties in known flood zones often carry higher insurance premiums and can be harder to resell or lease at strong rates — something worth weighing even if the price looks attractive today.
A Word on “Distress” Deals
Flooding season sometimes brings a wave of urgent, below-market property listings — owners looking to offload quickly after damage or repeated disruption. These can be genuine opportunities, but they require extra diligence: get a proper structural assessment, confirm there’s no ongoing water damage to the foundation, and price in the cost of any flood-proofing work you’d need to do.
The Bottom Line
Lagos’s flooding challenges are real, and they’re not going away this rainy season. But with the right due diligence — checking government advisories, inspecting during rain, asking the right questions of neighbors — you can significantly reduce your risk of buying into a problem property. At Planwell Homes, we build this kind of scrutiny into every transaction we support, because a good location is worth just as much as a good structure.
