Official Brussels rent grid
Reference rent in Watermael-Boitsfort
The official Brussels rent grid prices every dwelling profile per statistical sector; Watermael-Boitsfort counts 29 of them. The table below shows the commune-level reference for six typical profiles: the median of the sector references, and the full band across the commune.
The grid is published by the Brussels-Capital Region (loyers.brussels). It is indicative, not a cap, but it carries legal weight: Brussels leases must state the reference rent, and a rent far above the grid can be challenged before the regional rental commission (Commission paritaire locative). A rent far below it is also a classic scam marker.
