Detaching a Building From a Super-Condominium

Detaching a building from a super-condominium is not a free, unilateral act: it depends on whether that building can be separated from the others while keeping its own autonomy and, above all, on the fate of the assets and services that remain common to everyone. The main legal reference is the dissolution of the condominium governed by Articles 61 and 62 of the implementing provisions of the Italian Civil Code, read together with Article 1117 bis, which extends condominium rules to complexes made up of several buildings.

What detachment from a super-condominium means

Detachment means separating one or more buildings from the unified management of the super-condominium, so that the building stops taking part in the shared organisation and sets up its own. A super-condominium arises in fact when several autonomous buildings share common parts or services under Article 1117; dissolving that link therefore affects precisely those common parts.

The key distinction is between assets that can actually be separated and those that, by nature or purpose, keep serving every building. Detachment is conceivable for the former, while for the latter co-ownership survives even after the formal separation of management.

Partial dissolution under Articles 61 and 62

Article 61 of the implementing provisions states that where a building or group of buildings owned floor by floor by different owners can be divided into parts having the features of autonomous buildings, the condominium may be dissolved and the co-owners of each part may form a separate condominium. Applied to the super-condominium, this is the basis for letting a genuinely autonomous building leave the rest of the complex.

Dissolution can be resolved by the owners' meeting with the majority required by Article 1136, second paragraph, or ordered by the judicial authority on the application of even a single owner. Unanimity is therefore not strictly necessary for the separation itself, provided the requirement of divisibility into autonomous buildings is met.

Assets that stay common after detachment

Article 62 sets a decisive limit: dissolution does not affect rights over things that, by structure or purpose, remain at the common service of several buildings. In those cases co-ownership persists and continues to be governed by condominium rules. This is the point often overlooked by anyone who thinks detachment frees them from every shared expense.

• A road or access driveway still serving all the buildings stays common.
• A water, sewage or heating system serving several buildings is not split by detachment.
• A shared electrical substation or water treatment plant keeps generating expenses shared among all.
• Spaces and structures that cannot be physically separated without harm remain common.

In practice a building can leave the unified management for whatever is genuinely separable, yet keep contributing to the costs of assets that still serve it. Detachment therefore produces different effects depending on the asset in question.

Effect on expenses and thousandths tables

After detachment the super-condominium's thousandths (millesimi) tables must be revised: the departing building's shares are removed for assets no longer shared, while they remain for those still common. This is delicate accounting work, because an outdated table keeps charging the departing building for expenses it no longer owes, or conversely exempts it from costs it still has to bear.

The general criterion stays that of Article 1123: expenses are shared in proportion to the value of the units, or according to use when the asset serves the buildings unequally. Clear accounting is the best defence against disputes arising after separation.

The procedure in short

1. Check that the building has the features of an autonomous structure and can really be separated.
2. Identify the assets and services that will remain common even after detachment.
3. Bring the matter to the super-condominium meeting for the dissolution resolution, or apply to the judicial authority.
4. Update the thousandths tables and accounts, separating detached assets from those still shared.
5. Formalise the departing building's new separate management, without neglecting the obligations that remain.

The most common mistakes

The typical mistake is treating detachment as a total release from shared expenses: anyone who leaves but keeps using the shared road or system must still contribute. A second mistake is proceeding without updating the tables, producing wrong allocations and challengeable resolutions. A third is confusing the super-condominium with a simple set of fully autonomous buildings, where there is nothing to dissolve because no common parts exist.

Managing separation with software

Management software that handles complex structures with several buildings and multiple tables makes separation far tidier, because it lets you recalculate shares only for the assets still common and produce distinct accounts for the departing building and the super-condominium. AmministraPro manages condominiums and super-condominiums with multiple tables and separate statements, so the manager can steer detachment without losing control of the expenses that remain.
