Changing the Intended Use of a Unit in an Italian Condominium

Changing the intended use of a unit within an Italian condominium is, in principle, something the owner may freely decide, as an expression of exclusive property rights, but in practice it often runs into significant limits arising from the condominium bylaws, the protection of the building's architectural decorum, and respect for coexistence with other owners. Understanding where an individual owner's freedom ends and where condominium constraints begin is essential for a property manager handling situations of this kind.

The general principle: freedom of intended use

In the absence of specific prohibitions, every owner can generally put their unit to whatever use they prefer, for example converting a dwelling into a professional office or a storage room into a shop, provided they comply with the urban planning and building regulations governing change of intended use, which often require a separate municipal permit unrelated to condominium rules. Condominium law and urban planning rules run on parallel tracks: a change of intended use may be perfectly lawful from the municipal administrative standpoint and yet prohibited by the condominium bylaws, or vice versa.

Prohibitions set out in contractual bylaws

The most common limit on changing intended use comes from contractual condominium bylaws, meaning those drafted by the developer and accepted by every buyer in their respective purchase deeds, or approved unanimously by the assembly. This type of bylaws can lawfully prohibit specific uses, such as opening noisy commercial activities, non-hotel accommodation businesses, or activities that bring in public traffic incompatible with the building's quiet. A clause of this kind is fully valid and binding on all owners, including subsequent buyers, if properly registered in the land registry.

What assembly bylaws cannot do

The situation is different for bylaws of an assembly nature, approved with the ordinary majorities set out in Article 1136 of the Civil Code: since they cannot affect the real property rights of individual owners, they cannot validly introduce prohibitions on intended use that limit the exercise of exclusive ownership. A resolution that banned a particular use of a private unit by majority vote would be voidable at the request of a dissenting owner, unless the prohibition already had a basis in a pre-existing contractual clause.

Protecting the building's architectural decorum

Even when the bylaws contain no explicit prohibition, a change of intended use may still run into the general limit of protecting the building's architectural decorum, particularly when it involves changes visible from the outside, such as new signage, storefronts, independent entrances, or exposed technical equipment. In these cases the same principles that govern innovations to common areas apply: the work must respect the building's aesthetic harmony and must not significantly alter its original appearance, on pain of other owners being able to demand its removal or restoration.

Short term rentals and non-hotel accommodation

A highly topical issue concerns converting apartments into short term rental units or bed and breakfasts, a use that does not in itself change the residential nature of the unit under general civil law, but which can be prohibited or restricted by specific clauses in the contractual bylaws, considered lawful by case law when worded with sufficient clarity. In the absence of such a contractual ban, the activity generally remains permitted, subject to compliance with the ordinary rules on noise and disturbance to other owners.

Safety, building systems and increased shared loads

A change of intended use can also affect the building's systems and common areas, for example when it significantly increases foot traffic, raises consumption of shared utilities, or requires upgrades to fire safety and security systems. In these cases the property manager should carefully assess, with the help of a technical expert if needed, whether the change requires work on common areas that in turn needs an assembly resolution, keeping this technical aspect distinct from the individual owner's freedom to choose the use of their own unit.

The property manager's role when a change of use is proposed

When an owner announces the intention to change the intended use of their unit, the property manager should promptly check the content of the bylaws currently in force, distinguishing between valid contractual restrictions and limitations with no real legal effect, inform the assembly if the change also affects common areas, and maintain a balanced position that protects both the individual owner's right and the collective interest, without substituting for a judge's assessment of the legitimacy of the initiative in case of dispute.

Properly documenting communications received from owners, the content of the bylaws, and any resolutions connected with these changes is a task that a well structured management software significantly simplifies. AmministraPro gives property managers dedicated tools for document and communication management within a condominium: the features page describes these capabilities in detail, and the pricing section outlines the plans available for every type of firm.
