There are two main kinds of tenancy. The rights and responsibilities of both the landlord and the tenant depend partly on the type of tenancy that is created.

Tenancy Based on a Lease

One kind of tenancy is based on a written lease. When a tenant signs a lease with a landlord, the tenant agrees that the tenancy will last for a certain amount of time, usually one year. During that time, the monthly rent will stay the same and the landlord cannot end the tenancy (evict) unless the tenant fails to follow the conditions agreed upon in the lease. On the other hand, the tenant is committed to paying rent for the term of the lease. The tenant may only end the tenancy before the close of the lease term if the landlord agrees to early termination of the lease.

A lease is a good option for tenants and landlords seeking stability in a tenancy. Because it is a written agreement between the tenant and the landlord, it should contain all of the rules that will apply to the tenancy.

Tenancy-at-Will

The other kind of tenancy is called a tenancy-at-will, which means that the lease agreement lasts for as long as both parties want to do business with each other. Sometimes there is no written agreement at all in a tenancy-at-will, but often the tenant is asked to sign a form that says "Rental Agreement" or "Tenancy-at-Will" at the top. This form should include the amount of the monthly rent and basic rules.

A tenancy-at-will does not last for any set amount of time and does not end on a certain date, the way a lease does. In a tenancy-at-will the tenant pays the agreed-upon rent each month, for an indefinite period of time. Either the landlord or the tenant can decide to end the tenancy by giving the other party notice, either 30 days or one month before the due date of the next rent payment, whichever is longer. In this type of agreement, the rent can change according to the same terms (either 30 days or one month before the due date of the next rent payment, whichever is longer).

Obligations of the Landlord and of the Tenant

Whether a lease or a tenancy-at-will, the tenant must pay rent, follow the rules agreed upon with the landlord, and accept responsibility for any damage to the apartment that is more than just "normal wear and tear" (whether caused by the tenant or caused by a guest of the tenant). The landlord must provide an apartment that is safe and clean, in compliance with the rules set forth in the Massachusetts Sanitary Code, and must live up to any promises in the lease or rental agreement.

In either kind of tenancy, the tenant has a right to occupy the apartment and the landlord may only enter under certain circumstances. The landlord must arrange with the tenant in advance to enter the apartment to make repairs, to inspect the condition of the apartment, or to show the apartment to prospective tenants, buyers or real estate agents. However, the landlord may enter an apartment without a tenant's approval if it appears that the tenant has abandoned it.

Negotiations

Although it is not a part of any set of laws or regulations, it is important for both a landlord and a tenant to know that they can negotiate with each other over the terms of a lease. In general, the landlord should not rush a tenant to make a decision, and both parties should be very clear about the terms and conditions before either signs the lease. Any changes to which they agree should be written down into the lease in pen, making sure to cross out any sections that are changed by the terms of the negotiation.
