You've planned the perfect vacation, booked a beautiful rental property, and arrived ready to relax. Then you notice it: a musty smell, dark spots in the bathroom, or visible mold in the bedroom. Suddenly your vacation is compromised. What are your rights? What should you do?
Short-term rentals can have moisture problems, especially when maintenance is missed or a property sits closed. A listing, smell, or visible spot does not establish the extent or health significance of a problem; use the steps below to document and respond.
Before You Book
Research the Property
- Read reviews carefully—look for mentions of musty smell, mold, moisture
- Check multiple review sites
- Look at photos carefully for water stains or discoloration
- Note property age and maintenance mentions
- Check location—coastal, humid areas have higher risk
Questions to Ask Host
- When was the property last professionally cleaned?
- Is there a history of moisture problems?
- How is the property maintained between guests?
- Is there air conditioning (helps control humidity)?
- What is the policy if guests find mold?
Understand the Platform's Policy
Platform terms change and may differ by region and booking type. Read the current policy before booking and again if a problem occurs:
- Airbnb: check the current Rebooking and refund policy for covered reservation issues and its reporting window
- Vrbo: check the current VrboCare terms for qualifying bookings and covered incidents
- Direct bookings: review the host agreement and applicable local law
- Save the version of the cancellation, refund, and dispute terms that applied to your reservation
Upon Arrival: Inspection
Quick Walk-Through
Before unpacking, do a quick inspection:
- Use your nose—musty smells are the first warning
- Check bathrooms: under sinks, around tub, ceiling
- Look at bedroom window sills and closets
- Check kitchen under sink
- Look behind furniture against walls
- Check basement or lower level if applicable
What to Look For
- Visible mold (dark spots, fuzzy growth)
- Water stains on ceilings or walls
- Peeling paint or wallpaper
- Warped or damaged materials
- Excessive humidity (condensation on windows)
If You Find Mold
Document Everything
Before contacting anyone:
- Take photos and video
- Note exact locations
- Photograph any symptoms or reactions
- Keep records of all communication
- Note time and date discovered
Contact the Host
- Report immediately in writing (not just verbal)
- Use platform messaging for paper trail
- Be factual and specific
- Request remediation or alternative accommodation
- Set reasonable deadline for response
If Host Is Unresponsive
- Contact booking platform customer service
- Submit photos and documentation
- Request refund or rebooking
- Follow platform dispute resolution process
Your Rights
General Principles
A short-term rental may be subject to a booking agreement, platform terms, and local health or housing rules. Do not assume that a visible condition automatically creates a refund or legal remedy:
- The property should match the booking agreement and applicable local requirements
- A documented condition may support a request under a platform policy or local law, depending on the facts
- A platform review is not a ruling on health risk or local legal liability
- Local rental laws may apply
Platform-Specific Protections
Airbnb:
- Review the current Rebooking and refund policy for homes
- Covered reservation issues may qualify for refund or rebooking assistance, subject to the policy
- The current policy states a reporting window; follow the version and region that apply to your booking
- Document the condition, contact the host when feasible, and submit the requested evidence
Vrbo:
- Review the current VrboCare terms for qualifying bookings
- The program is limited to defined incidents and eligibility conditions
- Follow the current notice and claim process; it is not a general safety or money-back guarantee
Making the Decision
When You Might Stay
- Very minor surface mold in bathroom
- Host responds quickly and remedies
- No mold-sensitive individuals in your group
- Property is otherwise satisfactory
When You Should Leave
- Extensive visible mold
- Strong musty odor throughout
- Anyone in group has mold sensitivity or asthma
- Host is unresponsive
- Mold in sleeping areas or HVAC
- Health symptoms develop
Protecting Yourself During Stay
If you decide to stay while issue is addressed:
- Keep away from the affected area
- Use building ventilation or air conditioning only as appropriate for the conditions
- Do not sleep in a room with visible mold or a strong unresolved odor
- Keep messages, photos, and receipts in one record
- Seek medical care for concerning symptoms rather than relying on a rental inspection
Preventing Future Problems
Better Booking
- Choose properties with recent, detailed reviews
- Look for "Superhost" or "Premier Host" status
- Consider newer properties or professionally managed
- Ask about cleaning and maintenance protocols
- Read cancellation policies carefully
During Future Stays
- Always inspect on arrival
- Run AC or dehumidifier
- Use bathroom exhaust fans
- Report any water issues immediately
- Don't ignore musty smells
The Bottom Line
Document the condition, contact the host and platform promptly, follow the terms that apply to the reservation, and leave if the condition is unsafe or unresolved. A refund, rebooking decision, or legal remedy depends on the evidence, policy, agreement, and local law.
