You will find practical examples on contract registration, written communications and how to document faults and repairs. The instructions are designed to help renters prevent problems and avoid penalties, with concrete guidance on what to ask the owner and when to contact a competent authority.

Who is responsible for detectors and systems

Generally Italian law assigns the landlord the duty to deliver the property in safe and habitable conditions; for specific provisions on residential leases refer to national legislation[1]. In practice it is advisable to check the written contract: some clauses may specify who pays for installation or ordinary maintenance of fire devices.

  • Installing devices incompatible with the existing system, causing malfunctions.
  • Not reporting faults or repeated alarms to the landlord immediately.
  • Removing or disabling detectors without documenting the reason and informing the landlord.
  • Failing to keep receipts or written communications about interventions and expenses.
Always meet your obligations within deadlines to avoid losing rights.

Practical tips for tenants

Before any intervention, check the contract and send written communications to the owner. If you agree on cost sharing, always request a receipt and keep photos of the condition before and after repair. If the problem involves immediate safety, report it in writing and request urgent action; if there is inaction, document contact attempts.

  • Always write a formal communication and keep a copy of the transmission.
  • Photograph faults, device serial numbers and timestamps of reports.
  • Request that any modification be made by qualified personnel and documented.
Keep all rent receipts and communications organized and stored safely.

FAQ

Who should install smoke detectors?
Normally the owner is responsible for the property's safety and installation of main systems, unless the contract states otherwise; always check the contract and applicable law.[1]
What to do if the owner does not repair?
Document repair requests, send written communications and keep evidence. If you receive no response you can contact a competent body or consider legal procedures proportionate to the risk.
Can I deduct expenses from the rent or act unilaterally?
Do not deduct amounts from the rent without a written agreement: seek an agreed solution or consider formal measures, including legal action, only after collecting evidence and following the correct procedure.

How to

  1. Check the contract and note clauses on maintenance and expenses.
  2. Report the problem to the owner in writing and keep a copy.
  3. Document the urgency with photos and timestamps and request qualified intervention.
  4. If you need to register or update the contract, follow the official instructions for the RLI Form for registration with the Revenue Agency[2].
