19.02.2026, Fresh air in the home is important for a healthy indoor climate - but installing fly screens often leads to conflicts with landlords. According to Swiss tenancy law (Art. 260a OR), structural changes to rental properties are generally only permitted with the landlord's consent. Drill holes in window frames, firmly screwed constructions or permanent adhesives can lead to claims for damages when moving out.
Costly Consequences for Tenants
Tenancy law experts warn: Even seemingly small intrusions like drill holes are legally considered structural changes. Even if tenants fill the holes again, visible traces often remain. Landlords can then demand professional repairs - with several windows, costs can quickly amount to several hundred Swiss francs.
Drill-Free Systems as a Solution
"Many face the dilemma: they want to be legally secure but do not want to forgo living comfort,” explains Jürg Wälchli, insect protection expert at inschutz ag from Konolfingen. “This is why we specifically develop fly screens that do not require drilling."
The Bernese company offers custom- made insect protection screens that can be removed without a trace when moving out - ranging from tension frames and pleats to sliding doors. "The most important thing is that no traces remain after moving out," says Wälchli. "Our customers appreciate that they are on the safe side legally."
Checklist for Tenants:
- No drill holes without written permission
- Prefer drill-free systems
- Inform landlords in advance
- Ensure complete removal when moving out
- Take photos of the original condition
Experts advise: Even with drill-free systems, it is useful to inform landlords. This creates transparency and avoids discussions.
