Ban on Office or Studio Use in the Regulation: Valid?

A condominium regulation can ban using a flat as a studio, office or clinic only when the clause is contractual in nature and lists the prohibited uses clearly and specifically. A generic ban, such as an obligation to use the unit for residential purposes only, is construed restrictively by the courts and often is not enough to prevent a professional activity that does not alter the residential function of the premises.

The rule: use limits are construed narrowly

Clauses that compress an owner's powers are exceptions to the general principle of free enjoyment of the property. For this reason the Court of Cassation has repeatedly held that they must be read restrictively: in case of doubt, freedom of use prevails. Whoever relies on the ban must show that the clause bans precisely that use, with wording that leaves no room for ambiguity.

A contractual clause is required

A limit on the use purpose affects a real right over exclusive property. It therefore cannot be introduced by an assembly regulation approved by majority under Article 1138 of the Italian Civil Code. What is needed is a contractual regulation, that is, drafted by the builder and referenced in the deeds or approved unanimously by the owners. Only in this form does the clause bind all units and future purchasers.

• Valid ban: express list of prohibited uses, such as medical office, clinic, public-facing office, gym, school
• Doubtful ban: obligation to use the property as a residence, without further specification
• Ineffective ban: clause introduced or amended by the meeting by majority

The test of compatibility with residential use

Where the clause is generic, the judge assesses whether the professional activity is compatible with the residential purpose. A professional who receives a few clients by appointment, with no signs and no significant flow of people, as a rule does not breach the residential-use obligation. Different is the case of a busy multi-clinic with heavy footfall, noise, signs and occupation of common areas: here a change of use contrary even to more flexible clauses may arise.

Architectural decorum and use of common areas

Even without a valid use ban, the general limits remain: the owner may not alter the architectural decorum nor use common areas so as to prevent equal use by others, under Articles 1120, 1122 and 1102 of the Italian Civil Code. Unauthorised signs on the facade, notices in the entrance hall or permanent occupation of the courtyard can be challenged regardless of the use-purpose clause.

How to act when there is a dispute

A manager who receives a report must obtain the current regulation, check its contractual nature and enforceability, and read the exact text of the clause. Only after this analysis does a formal notice make sense. An action started on a generic or assembly-based clause risks dismissal and increased legal costs for the condominium, with possible liability for the manager who acted without proper authorisation.

Having the regulation, the tables and the history of each unit always available helps decisions be made with full knowledge. With AmministraPro the manager stores documents in an orderly way, prepares traceable communications and notices, and keeps the status of each matter under control: the features are shown on the /funzioni page and the available plans on /prezzi.
