Software choice

Which software you need to manage supercondominiums

A supercondominium arises when several autonomous condominiums share common assets and services, such as an access driveway, a water system or a green area. Article 1117-bis of the Italian Civil Code, introduced by the 2012 reform, extends condominium rules to these situations. Managing it is not the same as managing a larger condominium: you need accounting that holds together both the supercondominium level and that of the individual buildings, two-tier allocations and the handling of representation, which Article 67 of the implementation provisions regulates in a particular way when participants are numerous. Suitable software must mirror this multi-level structure, avoiding the errors typical of those who treat a supercondominium like any other condominium. This guide sets out the essential features for correct management.

What software for supercondominiums must handle

  1. A two-level structure: the supercondominium and the individual condominiums that make it up
  2. Allocation of common expenses across buildings and then among individual owners
  3. Consolidated accounting that holds the different levels together without confusion
  4. Management of owner representation under Article 67 of the implementation provisions
  5. Distinct notices and minutes for the supercondominium assembly
  6. Reports compliant with Article 1130-bis for each management level
  7. Transparency toward owners on how quotas are formed in a cascade
  8. A document archive organized by level and by building

A supercondominium is a multi-level structure

The fundamental difference from an ordinary condominium is the multi-level structure. In a supercondominium there are assets and services common to all buildings, which generate expenses to be allocated first among the participating condominiums and then, within each, among the individual owners. Software that treats everything as a single flat condominium cannot correctly represent this articulation and leads to wrong allocations.

Article 1117-bis of the Italian Civil Code, added by Law 220 of 2012, clarified that condominium rules apply to the supercondominium insofar as compatible. This means the obligations of transparency and accounting apply, but on a more complex reality, where every euro of common expense must be traceable along its descent from the common assets down to the individual owner.

Two-tier allocation

Allocation of supercondominium expenses typically happens in two steps: expenses for assets common to all buildings are divided among the participating condominiums by their own criteria, then each condominium's share is allocated internally among its individual owners by the building's thousandths, in compliance with the criteria of Article 1123 of the Italian Civil Code.

This double tier is the main source of error in manual management or with unsuitable tools. Software that natively handles the cascade of quotas, from the supercondominium down to the individual owner, ensures consistency and lets you show each owner how their quota was formed, an essential element of transparency when common expenses are disputed.

  • First tier: allocation of common expenses among the participating buildings
  • Second tier: allocation of each building's share among its owners
  • Traceability of the cascaded quota, from the common asset to the individual owner

Consolidated yet distinct accounting

The supercondominium has its own accounting, with a report compliant with Article 1130-bis, distinct from that of the individual condominiums that belong to it. Software must keep the accounting levels separate but allow a consolidated view, so the manager can read both the overall picture and each building's situation, without mixing movements from different levels.

Accounting separation is also a protection for owners: supercondominium expenses must not be confused with a single building's internal ones, and each level must have its own verifiable report. Software that mixes the levels makes transparency impossible and opens the way to disputes that are hard to clarify.

Handling representation

When a supercondominium has many participants, an assembly of all owners of all buildings becomes unmanageable. Article 67 of the implementation provisions of the Italian Civil Code provides that, beyond a certain threshold of participants, each condominium designates its own representative to the supercondominium assembly for ordinary management of common areas and for appointing the manager. Software must be able to track these representatives and handle notices accordingly.

Correctly recording who represents each condominium, with the related powers, avoids errors in minute-taking and in the validity of decisions. Orderly management of representation is an integral part of correct supercondominium administration, not a marginal detail, because it touches the very validity of resolutions on common assets.

Transparency and documentation by level

For owners, the complexity of a supercondominium can breed distrust: understanding why one pays a certain quota for a common asset far from one's apartment is not immediate. Software that makes the formation of quotas transparent and organizes documentation by level and by building helps the manager explain expenses and prevent disputes.

Frequently asked questions

What is a supercondominium from a legal standpoint?

It is the situation where several autonomous condominiums share common assets and services, such as an access driveway, a water system or a green area. Article 1117-bis of the Italian Civil Code, introduced by Law 220 of 2012, extends condominium rules to these situations insofar as compatible. It is not a larger condominium but a multi-level structure where common expenses must be allocated first among buildings and then among individual owners.

Why is expense allocation more complex in a supercondominium?

Because it happens on two tiers. Expenses for assets common to all buildings are divided among the participating condominiums by their own criteria, then each building's share is allocated internally among its owners by thousandths, in compliance with Article 1123. This double step is the main source of error with unsuitable tools: you need software that natively handles the cascade of quotas from the supercondominium to the individual owner.

Is the supercondominium's accounting separate from that of the individual condominiums?

Yes. The supercondominium has its own accounting with a report compliant with Article 1130-bis, distinct from that of the individual condominiums that belong to it. Software must keep the accounting levels separate but also allow a consolidated view. Separation protects owners: supercondominium expenses must not be confused with a building's internal ones, and each level must have its own verifiable report.

How is representation handled in the supercondominium assembly?

Article 67 of the implementation provisions provides that, beyond a certain threshold of participants, each condominium designates its own representative to the supercondominium assembly for ordinary management of common areas and for appointing the manager. Software must track these representatives and handle notices accordingly, because correctly recording who represents each condominium affects the very validity of resolutions on common assets.

Is software for ordinary condominiums enough for a supercondominium?

Usually not. Software that treats everything as a single flat condominium cannot represent the multi-level structure and leads to wrong allocations and confused accounting. To manage a supercondominium well you need a tool that natively handles cascaded allocation, consolidated yet distinct accounting by level, compliant reports for each level and representation under Article 67, while maintaining transparency toward all owners.
