Condensation Fixes for Apartments and Renters

Renters can fix a lot of condensation without owning the building — and should document what they cannot.

What you can usually do yourself

• Run bathroom fans during and after showers; report broken fans in writing
• Use lids and a range hood when cooking
• Avoid indoor drying racks when possible; use building laundry vents as designed
• Turn down or relocate portable humidifiers
• Open or gap curtains and blinds overnight
• Move furniture that blocks heat under windows
• Wipe sills each morning and keep a short humidity log
• Use removable draft stoppers and temporary film only where the lease and safety rules allow

What usually belongs to the landlord or building

• Failed sealed-glass units (fog between panes)
• Broken or missing exhaust fans and dryer vents that do not reach outdoors
• Chronic basement or envelope leaks
• Building ventilation systems, HRV/ERV maintenance, and shared HVAC settings
• Rotten sills, failed caulk, and structural mold remediation

How to report so it gets attention

Write a short dated note or email: which rooms, inside vs between panes, photos of wet glass and any damage, what you already tried (fans, humidifiers off, coverings open), and outdoor temperature on a typical wet morning. Ask for a specific fix (fan repair, dryer vent check, sealed-unit replacement) rather than a vague “windows are bad.”

Keep copies. Personal orders and informal chats are easier to forget than a clear paper trail.

This is general information, not legal advice about your lease or local housing rules.
