There are two sources that specify the right and responsibilities of landlords and tenants: the law and the lease. The local laws of every jurisdiction contain sections devoted to landlord-tenant relationships and rental arrangements that specify the rights and duties of each party.
Examples of areas covered by the law include the length of advance notice that must be given prior to eviction or under what circumstances the landlord is allowed to enter the tenant’s unit. The other source of duties and responsibilities is spelled out in the lease, which is the formal, binding contract agreed to by each party.
Aside from specifying the amount of rent and term of the rental, a lease can specify any conditions the parties agree to, provided they fall within the scope of the applicable law. Lease provisions that violate the law are unenforceable but do not invalidate the entire contract. Provisions that comply with the law remain in force. An example of a lease provision may specify when a tenant is allowed to move furniture or where trash is to be disposed.
