Clauses in the Condominium Bylaws That Limit Ownership: Are They Valid?

Anyone buying an apartment in an Italian condominium rarely imagines that a document signed years earlier, perhaps by the original developer, could limit what they can do with their own property. Clauses in the condominium bylaws that limit ownership are one of the most delicate areas of Italian condominium law, because they touch a constitutionally protected right, private property, and intertwine it with the collective interest in peace and architectural dignity. Not every restrictive clause is valid, and understanding the difference matters both for the property manager tasked with enforcing them and for the owner who wants to challenge one.

The key distinction: assembly bylaws versus contractual bylaws

The starting point is the legal nature of the bylaws. Assembly bylaws, approved by the owners' meeting with ordinary majorities, can regulate the use of common areas and the allocation of expenses, but cannot restrict the rights the law grants each owner over their exclusive unit. Contractual bylaws, by contrast, arise from an agreement accepted by all owners, typically because they were drafted by the developer and referenced in each individual deed of purchase, or approved unanimously at a later stage. Only this second type of bylaw can contain clauses that limit the intended use or the powers of the owner over their own unit.

The emblematic case of the bed and breakfast ban

In recent years Italian courts have repeatedly dealt with clauses banning the use of apartments for short term tourist rentals or bed and breakfast activity. The Court of Cassation clarified that such restrictions are legitimate only when contained in a contractual bylaw and worded clearly and specifically enough to leave no doubt that the intention was precisely to ban that use. A generic clause prohibiting commercial or nuisance activities in general terms does not automatically block short term rentals, if the activity itself does not generate disturbances beyond normal cohabitation.

The need for registration to bind future buyers

An often overlooked point concerns whether the restrictive clause can be enforced against someone who buys the unit later. If the restriction originates from a contractual bylaw referenced in the original purchase deeds, it binds the first owners who signed or accepted it. For the restriction to also bind subsequent buyers who did not take part in its formation, it must be registered in the property registers, or explicitly referenced in their own purchase deed. Without these elements, a new owner can argue they are not bound by the restriction, while still remaining subject to the general rules on nuisance and architectural decorum.

Which limitations are generally considered legitimate

Beyond the bed and breakfast case, contractual bylaws can contain several types of restrictive clauses, provided they are clearly worded:

• A ban on using units as medical practices or offices that involve significant public access.
• A ban on specific commercial activities, such as bars, restaurants or noisy businesses.
• A ban on keeping certain animal species, subject to the limits discussed for pets.
• Aesthetic constraints on external modifications, such as windows, awnings or air conditioning units.

The limits that no clause can override

Even a contractual bylaw has boundaries. It cannot contradict mandatory statutory rules, cannot violate fundamental personal rights, and, according to the most recent case law, cannot ban keeping pets in privately owned spaces. Moreover, restrictive clauses must be interpreted narrowly: in case of doubt, the owner's freedom to use their property as they see fit prevails, and whoever invokes the restriction must prove its contractual origin and unambiguous wording.

The property manager's role in enforcing clauses

The property manager cannot create new restrictions, but is required to enforce those legitimately present in the contractual bylaws, flagging violations and, if necessary, bringing the matter before the assembly or taking legal action on the owners' mandate. Before formally challenging a violation, it is good practice to carefully verify the nature of the applicable bylaws and the exact wording of the clause invoked, because action based on an invalid or unenforceable clause exposes the condominium to the risk of losing the case.

Freedom to dispose of one's property is the rule; a restrictive clause, to be effective, must be the clearly intended exception.

A practical approach

Before taking any action, it is always worth retrieving the full text of the bylaws and verifying whether they are contractual or merely assembly based, checking the deeds of the units involved. A good digital management tool helps keep and quickly retrieve these documents, preventing the condominium's institutional memory from being lost as property managers change over time. AmministraPro is built with exactly this kind of need in mind, offering an always accessible digital archive: the features page shows the tools dedicated to document management, and the pricing section lists the plans available for property management firms of every size.
