Create a policy for entertaining guests. Discuss whether fellow tenants may have overnight guests and how long guests may stay. As a courtesy to housemates and neighbors, be sure to set rules for your guests - especially when alcohol will be consumed. Discuss appropriate behavior and acceptable noise levels with your housemates and their guests. Also, be aware that local ordinances prohibit high levels of noise, underage drinking and disorderly conduct.
Tenants can face hefty fines and even jail time for violations of such laws.
Consider the possibility of fellow tenants leaving. Even if you discussed your desires and expectations before you moved into your rental, housemates may still decide to move out. Everyone should talk about this possibility before moving in. Decide who will be responsible for finding a new tenant. Remaining housemates may feel they should have the right of filling the vacancy since they will be living with the new tenant.
