A lease is a contract between you and your landlord. This means that only the terms that are in your lease apply to your situation. Other tenants may have different terms in their leases with the landlord. A landlord generally does not have to treat all tenants the same. But a landlord cannot discriminate against a particular tenant on certain grounds related to human rights. You can change a lease if all of the parties who signed the original lease agree to the change. Consequently, you may want to try to negotiate with the landlord to see if they will lower the rent for you to match your neighbor’s. The landlord is not under any obligation to agree to such a change. Finally, make sure that any change in rent is in writing.
