Construction Contracts for Condominium Works: Useful Clauses

Every time a condominium commissions major maintenance work, from repainting the facade to replacing the elevator system, the building manager signs a condominium construction contract on behalf of the owners. A generic text copied from an online template exposes the building to delays, disputes over material quality and difficulty enforcing warranties. Clauses are not a bureaucratic detail: they are the tool through which the manager turns an assembly decision into verifiable obligations.

The manager's role as contracting party

When the assembly approves a job and authorizes its execution, the building manager acts as agent for the owners and signs the contract in that capacity, not personally. It is therefore essential that the assembly resolution clearly states the scope of the works, the maximum spending amount and, where applicable, the chosen contractor, so the contract faithfully reflects the mandate received. A contract that departs from the resolution, in amount or scope, exposes the manager to personal liability toward the owners.

Scope of works and technical specifications

The clause defining the scope of works should be as precise as possible, attaching a technical specification that describes materials, workmanship, quantities and expected quality standards. A generic reference such as facade restoration work leaves too much room for interpretation by the contractor and makes it difficult later to challenge execution choices that were never agreed upon. Attaching drawings, a bill of quantities and material data sheets significantly reduces the risk of disputes over the conformity of the finished work.

Execution timeline and late penalties

The contract must set a start date, a maximum duration and, where possible, a schedule with intermediate milestones. Alongside the timeline, a penalty clause should automatically quantify the damage caused by delay, for example a percentage of the contract amount for each day of delay beyond the agreed deadline, capped at a maximum. A well calibrated penalty spares the manager from having to prove in court the extent of the damage suffered, simplifying recovery of the amounts owed.

Progress payments and the state of works

Linking payments to the actual state of works, commonly tracked through progress reports, is one of the most effective protections for the building. Instead of paying installments on fixed dates regardless of the site's real progress, the contract should require that each interim payment be conditional on verification, by the works supervisor or the manager, of a percentage of work actually completed. It is also good practice to withhold a portion, often called a retention, to be released only after final testing and confirmation that there are no defects.

Labor compliance checks on the contractor

Before signing and periodically during the works, the manager should request the contractor's certificate of regularity regarding social security and insurance contributions, known in Italy as the DURC. The contract can expressly require the contractor to provide a valid DURC as a condition for payment, along with a commitment to traceable financial flows toward subcontractors and suppliers.

Guarantees, insurance policies and civil liability

A solid condominium construction contract requires the contractor to carry third party civil liability insurance, covering any damage to people or property during the works, including common areas and neighboring units. It is also advisable to include a warranty against defects in the work, in addition to the ten year statutory warranty for serious structural defects, with clear terms on how and when the owners can invoke these protections.

Subcontracting, safety and site coordination

The contract should regulate whether subcontracting is permitted, making it subject to written authorization and keeping the main contractor jointly liable for the work of any subcontractors. On the safety side, it should reference obligations regarding the safety and coordination plan where required by law, the appointment of a safety coordinator during execution if needed, and rules for resident access to the site.

• Scope of works with an attached technical specification and defined amount
• Schedule with start date, maximum duration and late penalties
• Payments linked to progress with retention held until final testing
• Valid labor compliance certificate as a condition for payment
• Civil liability insurance and warranties against defects
• Rules on subcontracting, safety and site access

Withdrawal, termination and handling disputes

Finally, the contract must specify the conditions under which the condominium can withdraw or terminate the relationship, for example in case of serious breach, abandonment of the site or substantial deviation from the specifications, indicating the financial consequences of each scenario. A clause regulating the timing and form of written complaints helps formally document any problems, a valuable element should the matter escalate into a dispute.

Drafting a complete condominium construction contract takes time and attention, but it protects both the owners and the building manager from future disputes.
