Houston's Official Flood Map

June 20, 2025

Houston is a city that receives heavy rainfall and occasionally faces severe storms. For that reason, flood risk is a topic that cannot be overlooked — especially for those thinking about buying a home or who have recently moved to the area. After intense rainfalls, some neighborhoods in the city can experience flooding. This can cause not only significant financial damage but also serious emotional hardship.

So what should you do?

Houston and Harris County offer an interactive map online, open to everyone, to inform and support the public on this issue. With this map, you can find out whether a home or neighborhood falls within a 100-year or 500-year flood risk zone. It also shows creek beds, flood corridors, and areas that have experienced flooding in the past in detail.

This map is an especially valuable resource for anyone in the process of buying a home. Because your decision can be directly affected not just by the price, location, and appearance of a home, but also by the natural risks you may face in the future.

What does buying a home in a high flood-risk area mean?

If you're planning to buy a home in Houston, we strongly recommend checking this map first.
Remember, taking precautions is far easier and more cost-effective than trying to recover from damage after the fact.
