General Contractor Liability in Building Bonuses: Trends Regarding the Nature of the Contract
7 min read · Updated November 2026 · Editorial oversight: Avv. Federico Papa
The rise and fall of building bonuses has triggered a season of intense civil litigation, shifting focus from tax aspects to strictly contractual ones. According to the specialized press and recent industry analyses between 2023 and 2024, the central issue concerns the legal qualification of the General Contractor (GC) and its degree of liability for defects in works performed by third-party firms. While many operators have tried to shield themselves behind the status of mere agents without representation, jurisprudence on the merits is starting to consolidate an approach that prioritizes the economic substance of the relationship. This article examines how the nature of the bond between the principal and the General Contractor determines the extent of warranties for non-conformities and defects, clearly distinguishing the issue from the criminal profiles of fraud previously discussed. Through the twin case of Gaio Sventura, we will see how coordination clauses almost never exempt the contractor from liability for the actions of their agents, defining the boundaries of business risk in condominium and private settings.

In brief
The article analyzes the private nature of the relationship between General Contractors and clients regarding building bonuses. It focuses on the distinction between a contract for works and mandate contracts, examining civil liability for construction defects and subcontractor default under Art. 1228 of the Civil Code. Prevailing jurisprudence has started to consolidate the qualification of the General Contractor as a lead contractor, making them directly liable for the technical failures of those employed to execute the works.
The facts
The case arises from the saturation of the subsidized renovation market, where many entities took on the role of General Contractor to manage turnkey packages including invoice discounts. According to reports from publications like NT+ Condominio and Ediltecnico, cases have multiplied where clients, faced with incomplete or clearly defective works, were met with the GC's objection of lack of passive legal standing.
The procedural stage of these disputes is currently at the first instance of judgment on the merits. Specifically, numerous courts are called upon to decide whether the GC should be liable for damages caused by subcontracting firms or if their function was limited to mere financial and administrative intermediation. The recurring defense thesis of General Contractors is that, acting as agents for credit management and coordination, liability for poor execution rests solely with the executing companies chosen by the client or specified in the contract.

The rules at play
The central provisions for resolving the conflict are contained in the Civil Code:
- Article 1655 c.c. (Contract for works): defines the contract whereby a party undertakes to perform a work with the organization of necessary means and management at their own risk, an element distinguishing the entrepreneur from a mere intermediary.
- Article 1703 c.c. (Mandate): regulates the obligation to perform legal acts on behalf of others, often invoked by GCs to limit their liability to administrative management only.
- Article 1228 c.c. (Liability for the acts of assistants): establishes that a debtor who uses third parties to fulfill an obligation is liable for their intentional or negligent acts.
- Article 1667 c.c.: governs the warranty for non-conformities and defects in the work, placing the burden of eliminating defects at their own expense on the contractor.
What jurisprudence says
Jurisprudence on the merits has begun to clarify, applying 2017 Supreme Court precedents by analogy, that the qualification of a contract as a contract for works or a mandate does not depend on the nomen iuris chosen by the parties, but on the actual substance of the relationship. If the General Contractor selects subcontractors, coordinates workers, and receives compensation linked to the total value of the work (and not just a commission), they must be considered a contractor in all respects.
The courts specified that the GC is directly liable to the client for construction defects under Art. 1228 c.c., as subcontractors act as their assistants in executing the agreed unified plan. Furthermore, it has been established that contractual clauses excluding the GC's liability for construction defects are void if they constitute an exemption for gross negligence, especially when the breach concerns essential supervision of safety and structural stability of buildings.

What it teaches professionals
- Contract drafting: avoid qualifying as mandate relationships that exhibit traits of a contract for works, to prevent creating liability exemption expectations that would be struck down in court.
- Policy verification: ensure that the General Contractor has specific coverage for contractual liability arising from subcontractors' actions (ten-year post-completion and RCT/O).
- Litigation management: in the presence of defects, act promptly against the GC to interrupt limitation and forfeiture periods, without being misled by referrals to executing firms.

Frequently asked questions
Can a General Contractor shift liability to subcontractors?
No. If the relationship is qualified as a contract for works, the General Contractor is directly liable to the client for the actions of third parties employed under Art. 1228 c.c.
What happens if the contract explicitly states the GC is not liable for defects?
Such clauses may be void or ineffective, especially if they constitute an exemption from liability for intentional misconduct or gross negligence in site supervision.
How do you distinguish a mandate from a contract for works in the Superbonus context?
One evaluates decision-making autonomy, the choice of suppliers, and the compensation structure: if the GC manages the site and subcontractors as their assistants, it constitutes a contract for works.
