Smoking and vaping are prohibited inside most transient houses to protect the property from odor and fire hazards, though some hosts designate an outdoor area where guests may smoke. Alcohol consumption is generally permitted inside transient houses as part of normal social activity, but excessive drinking that leads to noise complaints, property damage, or disruptive behavior is grounds for termination of the booking. Review the house rules on Transienthome.com carefully for the property’s specific policies on smoking, vaping, and alcohol, and follow them strictly to avoid losing your security deposit or being asked to leave.
