The parliament in the Brussels-Capital Region limited rent increases in the capital for one year in Belgium.
It said it separated houses into classes from A to G, according to energy efficiency.
Landlords can increase rents by the inflation rate for homes with high-energy efficiency that are coded A, B, C and D.
Rents in home in the E-class can be increased by 50% of the inflation rate.
Low-energy-efficiency houses, F and G, were exempted from rent increases.
Thirty percent of houses in Brussels are classified in G class, while 15% in E and 20% in D.
The inflation rate was at it highest since 1975 — at 11.27% in September.
Natural gas prices increased 134.9%, electricity prices were up 81.3% and heating oil prices rose 56.3% year-on-year last month.
