Starting from 2024–2025, Italian regulations (Legislative Decree 101/2020) impose important obligations on those building new homes, with the goal of preventing Radon gas infiltration.
Required Technical Measures
New constructions must include effective technical solutions, such as:
- Radon gas barriers in the foundations
- Ventilated crawl spaces or underfloor ventilation systems
- Specific materials and waterproofing systems that reduce gas entry
These measures must be included from the design phase to ensure a healthy and safe indoor environment.
Risk Zones and Regional Classification
Italian regions are required to identify areas with a high probability of Radon presence. In these zones, regulations are even stricter, and designers must comply with more rigorous standards.
Radon and Home Buying: What to Ask the Builder
If you’re considering purchasing a newly built home, it’s essential to ask about the anti-Radon measures taken.
Ask the builder:
- If the area is classified as a Radon risk zone
- What prevention techniques have been used
- Whether official tests and measurements have been conducted
This information is important to protect your health and ensure the long-term value of the property.
Conclusion: Living Safely Is Possible
In particular, it can be said that the average concentration of Radon gas in Liguria is lower than the national average.
The Radon regulations represent a significant step forward toward safer and healthier homes. If you’re building or buying a home today, make sure Radon gas isn’t a hidden threat.
