Practical regulations
Managing withdrawal from non-essential common services
Some building services, such as centralized heating or a shared television antenna, are not considered essential under Italian law, and an individual unit owner may withdraw from using them through formal disconnection. Article 1118 of the Italian Civil Code governs this possibility for centralized heating, on the condition that the disconnection does not cause significant operational imbalances or additional costs for the remaining owners. An owner who withdraws still remains obligated to contribute to the costs of preserving and maintaining the shared system. Managing this correctly requires a clear procedure: formal notice, technical assessment, an assembly resolution when needed, and adjustment of accounting and cost allocation. Here is how to proceed step by step.
Which services truly qualify as non-essential
Not every common service can be the object of unilateral withdrawal. The relevant distinction is between essential services, whose interruption by a single owner is not permitted because it would affect the building's safety or overall condition, and divisible or non-essential services, where individual consumption can be isolated without compromising the general operation of the system.
The case expressly regulated by Article 1118 of the Civil Code is centralized heating: an owner may disconnect from the shared system if they demonstrate, through a technical report, that no significant thermal or hydraulic imbalance and no meaningful additional cost for the remaining connected owners results from the disconnection. Other services often treated as non-essential in practice and case law include the centralized television antenna, now largely superseded by independent digital terrestrial reception, ancillary intercom or video intercom connections, and optional additional services approved by the assembly, such as evening concierge or supplementary surveillance.
The disconnection procedure: notice and technical report
An owner who intends to withdraw must give formal notice to the property manager, stating the intention to disconnect and attaching a technical report drafted by a qualified professional confirming that no imbalance will affect the shared system. Prior authorization from the assembly is not required for disconnection from centralized heating, since the law treats it as an individual right exercised through simple notice, but the technical report is a substantive condition: without it, the disconnection can be challenged and the manager has grounds to oppose it.
Upon receiving the notice, the property manager must verify that the documentation is complete and inform the assembly at the next available meeting, so that the effective date of disconnection and its impact on subsequent cost allocation are formally recorded. It is also advisable to check the status of meters or heat cost allocators, where present, to establish precisely the point from which the owner stops being counted among the active users of the service.
Residual costs that remain the withdrawing owner's responsibility
Disconnection does not release the owner from every contribution obligation. Article 1118 is explicit: an owner who disconnects remains required to contribute to the costs of preserving the heating system and keeping it operational, as well as to any extraordinary maintenance or regulatory upgrade costs for the centralized system, where applicable.
In practice, this means the property manager must continue to include the disconnected owner in the allocation for cost items unrelated to actual consumption, such as ordinary boiler maintenance, mandatory inspections, and replacement of shared components, while excluding them from the variable share tied to thermal consumption. For services other than heating, such as the antenna or optional services approved by majority vote, the allocation of residual costs follows the criteria set out in the resolution that established the service: if the service was activated by majority vote and a dissenting owner had already expressed opposition at the assembly, their contribution position may differ from that of owners who joined the service from the start.
Accounting implications and updated cost allocation tables
From an accounting standpoint, disconnection requires opening a new cost allocation table or updating the existing one, distinguishing the fixed share, owed by everyone including the disconnected owner, from the variable share, owed only by active users. This distinction must be applied starting from the budget following the disconnection notice and maintained in the final statements, with the two components shown separately.
Property management software such as AmministraPro allows managers to handle multiple allocation tables and automatically apply the fixed and variable shares to disconnected owners, avoiding manual allocation errors and keeping a record of resolutions and notices received. It is good practice to keep the technical report, the owner's notice, and the minutes acknowledging the disconnection in a digital archive, so the correctness of the applied allocation can be demonstrated at any time, even years later.
Frequently asked questions
Is assembly authorization required to disconnect from centralized heating?
No, Article 1118 of the Italian Civil Code establishes disconnection as an individual right of the owner, exercised through formal notice accompanied by a technical report confirming that no imbalance will affect the shared system. The assembly does not need to authorize the disconnection, but the property manager must be informed and must verify that the technical documentation is actually adequate, because without it the disconnection can be challenged by other owners or by the manager.
Does a disconnected owner still pay anything for heating?
Yes, they remain obligated to contribute to the costs of preserving the centralized system, meaning the ordinary and extraordinary maintenance needed to keep it functional for the other owners, plus any regulatory upgrade costs. They do not pay the variable share tied to actual thermal consumption, since they no longer use the service. This distinction must appear clearly in the financial statements.
What happens if the disconnection causes an imbalance in the shared system?
If the technical report does not reliably rule out significant operational imbalances or additional costs for the other owners, the disconnection is not legitimate and can be challenged at the assembly or, in case of persistent dispute, before a court. This is why the technical report prepared by a qualified professional is a substantive step in the procedure, not a mere formality.
Does withdrawal from services other than heating, such as the shared antenna, follow the same rules?
There is no specific rule equivalent to Article 1118 for other divisible services, so the framework often depends on the building regulations or the resolution that established the service. The prevailing criterion recognized in case law is generally that an owner may give up using non-essential ancillary services without affecting the others, but remains liable for the costs of preserving structural common parts, such as the wiring or the centralized system as a whole, when it cannot be separated.
How does a property manager track disconnected units over time?
Proper management requires an updated archive of disconnection notices, attached technical reports, and the resolutions acknowledging them, along with allocation tables that consistently distinguish the fixed and variable share for each affected service. Digital tools such as AmministraPro allow documents to be linked to each owner's file and automatically apply the correct allocation in subsequent statements, reducing the risk of errors as property managers change over time.
