🦠 Mold or damp in my rental — who do I report to?

Direct answer

Damp, mold or leakage in rental: landlord must repair. (1) Write a letter demanding repair within 6 weeks (photos attached). (2) No response: city Building Supervision 14 020 can force landlord to repair. (3) Severe defects: Huurcommissie 088 1600 300 can temporarily reduce rent (20-60% depending severity). (4) Health complaints: inform GGD, see GP. (5) Don't withhold rent: keep paying, Huurcommissie handles reduction. Landlord liable for healthy + safe home.

Frequently asked questions

Do I repair myself?

No, mold + damp from structural defects = landlord maintenance. Own ventilation error is exception — needs proof.

Can I withhold rent?

Not without process — possible eviction ground. Request official Huurcommissie reduction, then you're protected.

Harmful for child's health?

Yes, children highly sensitive. GP + GGD advice, written statement strengthens case for relocation/social housing urgency.
