The law in force at the federal level of Belgium in terms of residential leases is the law on rents. The last update of this federal law took place during its 14th edition in March 2013.
In recent years, each region has instituted its own regional regulations concerning residential leases. The Brussels-Capital Region has put in place a Housing Code which replaces the federal law on residential leases since January 1, 2018.
The housing code of the Brussels region largely incorporates the main lines and rules of ordinary 9-year leases from the old federal legislation.
