Adding Someone onto a Tenancy Agreement: What You Need to Know

If you are a landlord, property manager or tenant, adding someone onto a tenancy agreement can be a daunting task. It is important to understand the responsibilities, rights and obligations of both parties involved before making any changes to a lease agreement. In this article, we will explore the process of adding someone onto a tenancy agreement and what you need to know.

Reasons for Adding Someone onto a Tenancy Agreement

There are various reasons why you may need to add someone onto a tenancy agreement. Some common reasons include:

– The tenant wants to add a roommate or partner to share the rent and living expenses

– A family member or friend wants to move in with the tenant and become a co-tenant

– The landlord wants to add a new tenant to replace a departing one

– The landlord wants to add a guarantor or co-signer to the lease agreement for financial security

Regardless of the reason, adding someone onto a tenancy agreement requires consent from all parties involved and an amendment to the existing lease agreement.

Process of Adding Someone onto a Tenancy Agreement

The process of adding someone onto a tenancy agreement depends on various factors, such as the type of lease agreement, the length of the tenancy, the number of occupants, and the rules and regulations of the local housing authority.

Here are the general steps you need to follow:

1. Check the lease agreement: The first thing you need to do is check the current lease agreement to see if it allows for additional tenants. If not, you may need to renegotiate the lease agreement with the landlord or property manager.

2. Get consent from all parties: Once you have established that you can add someone onto the tenancy agreement, you need to get consent from all parties involved. This includes the landlord, the tenant, and the new tenant.

3. Sign a new lease agreement: The next step is to sign a new lease agreement that includes the additional tenant. This document should outline the rights and responsibilities of all tenants, including rent payments, utilities, and maintenance.

4. Inform the local housing authority: If you live in subsidized housing or rent-controlled units, you may need to inform the local housing authority of the new tenant. Failure to do so may result in a violation of the housing rules and regulations.

5. Update the rent payments: Depending on the agreement between the tenants, the rent payments may need to be adjusted to accommodate the new tenant`s share.

6. Conduct a move-in inspection: Before the new tenant moves in, it is advisable to conduct a move-in inspection to document the condition of the property and ensure that everything is in working order.


Adding someone onto a tenancy agreement can be a complicated process, but it is achievable with proper planning and communication. As a landlord or tenant, it is important to be aware of your legal rights and responsibilities, and to consult legal or housing professionals if necessary. By following these steps, you can ensure a smooth transition for all parties involved.
