Adding a Roommate to Your Lease in Maryland: A Guide

If you’re renting in Maryland and want to bring in a roommate, it’s important to know how to properly add them to your lease. Doing so can protect both you and your new housemate, help avoid disputes with your landlord, and ensure everyone’s rights are respected under Maryland law.

Understanding Your Lease and Maryland Tenant Law

Before inviting a friend or family member to share your rental home, review your current lease agreement. Most leases in Maryland have clear terms regarding occupancy and the process for adding, removing, or substituting tenants. Maryland rental laws, including the Maryland Code, Real Property Title 8, govern the rights of tenants and landlords in these situations.[1]

Why Add a Roommate to Your Lease?

  • Ensures everyone is legally recognized and responsible for the unit
  • Protects your deposit and rights if disputes arise
  • Makes rent payment obligations clear for all parties

Failing to officially add a roommate could result in lease violations, risking eviction or other legal issues.

Landlord Approval and Common Lease Requirements

Most Maryland leases require written landlord approval before adding a new occupant. Always communicate early with your landlord or property manager. Typically, you may need to:

  • Submit a written request to your landlord
  • Provide information about the prospective roommate (such as name, contact, and ID)
  • Complete a rental application and undergo background or credit checks, as required by the landlord’s policy

Your landlord cannot unreasonably refuse consent, but they can set reasonable requirements (like income or background checks). Careful communication helps maintain a good relationship with your landlord.

Required Forms and Official Processes in Maryland

While Maryland does not have a single statewide government form for adding a roommate, most landlords use their own documents. However, here’s how it usually works:

  • Lease Addendum: Often called an "Addendum to Lease" or "Roommate Agreement Addendum," this document is prepared by the landlord or property manager. It officially lists your new roommate and updates rental responsibilities.
  • Rental Application: Your landlord may require your roommate to complete a new rental application. This is not a state form, but your landlord should provide it.

For example, if your roommate is joining your current lease in Baltimore, your landlord may ask them to fill out a rental application and then sign a lease addendum reflecting the update.

For matters of tenancy disputes or unresolved issues, the Maryland District Court (Landlord-Tenant Division) handles residential tenancies across the state.[2]
