Flooding is one of the biggest hidden risks for homebuyers in Lagos. Every rainy season, tenants and landlords face damage, financial loss, and stressful relocations, all because crucial warning signs were ignored before purchase or rent. Understanding why flooding happens and how to detect it early can save you from years of regret.
Why Lagos Homes Flood
1. Poor Drainage Systems
Many Lagos neighborhoods lack proper drainage channels. Even when drains exist, they are often too narrow, blocked, or poorly maintained. As a result, rainwater has nowhere to go and flows straight into compounds, streets, and homes.
2. Building on Natural Water Channels
In high-demand areas, some developers cut corners by building on wetlands, canals, and natural drainage paths. These lands naturally retain water, so properties built on them flood easily,no matter the design.
3. Overdevelopment Without Proper Planning
Some estates cram too many buildings into small spaces, leaving no room for water flow, soakaways, or green areas. Concrete everywhere means rainwater gathers instead of being absorbed.
4. Low-Lying Terrain
Areas like Ajah, Lekki, and parts of Lagos Island sit below sea level. Heavy rainfall combines with rising tides, increasing the risk of severe flooding even in new or “luxury” developments.
How to Avoid Buying a Flood-Prone Home
1. Visit the Property After Rain
One of the simplest hacks: visit right after a rainfall or during the rainy season. If you see stagnant water in the compound, high tide marks on walls, or soggy soil, run.
2. Ask Neighbors (Not the Agent)
Agents sugarcoat. Neighbors tell the truth. Ask shop owners, security men, or residents how the area behaves during heavy rain.
3. Check the Drainage Network
Walk around the street. Are drains open? Blocked? Too shallow? Do they lead anywhere, or do they stop abruptly? A house is only as flood-safe as the street it sits on.
4. Inspect the Height of the Property
If the house sits below road level, it is highly prone to flooding. Homes should be slightly elevated compared to the surrounding street.
5. Research the Area Online
Search the area name with terms like “flooding,” “rain,” or “Lekki flood.” You’ll often find news reports or social media posts.
Final Thoughts
Flooding in Lagos isn’t always a matter of bad luck, most times, it is predictable. By checking the land quality, drainage, neighborhood history, and timing your inspection right, you can avoid costly mistakes. Before you sign anything, make sure the home you’re paying for won’t turn into a river once the rain starts.
