Home safety (fire, CO, gas) 3 min read · published September 11, 2025

As a tenant in Portugal, reporting changes of address, contact details or safety issues (fire, carbon monoxide, gas) requires attention to deadlines, evidence and notification methods. This article explains in plain language the most common mistakes that can harm your rights, how to prepare documentation, when to request repairs from the landlord and how to act in emergencies. It includes practical steps to record messages, file receipts and submit formal complaints. It also indicates where to find official forms and which legal rules apply to tenancy. The goal is to help you communicate safely, avoid unnecessary conflicts and protect your home safety.

Before Reporting

First check your lease and the landlord's obligations regarding safety (detectors, gas, ventilation). Gather evidence before sending any notice: photos, call logs and repair receipts. If the situation involves fire, gas or carbon monoxide risk, inform in writing immediately and request urgent intervention.

  • Failing to keep proof of communications with the landlord, such as emails or photos of faults.
  • Missing legal deadlines or failing to notify in writing within specified timeframes.
  • Using informal channels instead of delivering notices or officially accepted forms.
  • Underestimating safety risks (gas, smoke, carbon monoxide) and not requesting inspection immediately.
  • Failing to demand repairs when habitability is affected.
Keep records of all communications with your landlord.

How to Report Changes

When reporting changes (address, contacts or conditions affecting safety), prefer a written record that allows later proof: email with confirmation, registered letter with acknowledgment of receipt or an official form when applicable. State the problem clearly, the dates and request a deadline for resolution. If you refer to applicable legislation, mention the NRAU and complementary rules as needed [1].

Always respond to formal notices within the indicated deadlines to protect your rights.

Practical Points for Safety

If you face risks of fire, gas or carbon monoxide, note times, turn off safe sources if you know how and, in immediate danger, contact emergency services before informing the landlord. Record any professional intervention and keep invoices.

  • Contact emergency services if there is imminent danger.
  • Document technician interventions and keep invoices and reports.
  • Use official forms when the law or local procedure requires them.
