Can objects be freely hung on windows, railings, balconies?

In principle, a landlord or tenant can hang objects on the windows, railings or balconies of his apartment.

It is nevertheless necessary to ensure several points. It is necessary to:

• Check the clauses of the condominium rules. Certain clauses may, for example, prohibit or limit the spreading of linen on windows and balconies, the placing or hanging of various objects (planters, tables, lights, etc.) on balconies, terraces, railings or the affixing of banners or permanent decorations visible from the outside.
• Respect the destination of the building. Even without a specific clause, a large and visible size of the balcony or an installation that clearly degrades the aesthetics in a luxury building may be prohibited, as they harm the overall harmony of the building.
• Respect the rights of other occupants of the building and the safety of bystanders. The settled object must not be dangerous, impair the structure or solidity of the building or create an unsanitary situation.
• Respect the city planning rules. If the object or installation changes the exterior appearance (canopy, balcony closure, large facade fixture, etc.), a prior declaration may be required and the city planning authority will check compliance with local regulations (MORE etc.).

If these conditions are met, the occupant of the condominium can then freely hang an object from his window, balcony or railing.
