Popular Bangkok Condos in High Flood-Risk Districts
· RealData warning list
Some Bangkok districts go knee-deep every monsoon. The northern and eastern outskirts where the 2011 great flood started, plus the southern coastal khet built on tidal flats. We compiled a 0–5 risk score per district from BMA Drainage Department reports, JICA flood-mitigation studies, and 2011 inundation records — see the Bangkok flood map for the full map.
And yet, condos in those Level 4-5 districts keep getting bought. Influencers and agents don't usually mention the flood part. We compiled the buildings with the most active listings inside high-risk districts, so you can verify before you buy.

Frequently asked questions
Which Bangkok areas have the worst flood risk for condo buyers?▾
The Bangkok Metropolitan Administration (BMA) flood map designates Level 4–5 (highest risk) in northern and eastern districts including Don Mueang, Bang Khen, Lat Phrao, Min Buri, and Nong Chok. During heavy monsoon seasons these areas experience 30–80cm of standing water. Active condo listings exist in all these zones, often without flood disclosure.
How does BMA rate flood risk in Bangkok?▾
BMA uses a 1–5 scale based on historical flood depth and drainage capacity: Level 1 = no significant flood history; Level 2 = minor puddles; Level 3 = 10–30cm; Level 4 = 30–80cm; Level 5 = over 80cm. The 2011 mega-flood affected vast parts of Bangkok at Level 4–5. RealData maps all condos against this BMA dataset.
Are condos in Bangkok flood zones cheaper?▾
Not significantly. RealData analysis shows flood Level 4–5 condos often list near market price, as flood risk is rarely disclosed in listings. Buyers focused on central-Bangkok alternatives can filter for Level 1–2 areas first, then compare prices within those safer zones.
