Lessee shall not assign this Lease or sublet any portion of the Premises without prior written consent of the Lessor, which shall not be unreasonably withheld. Any such assignment or subletting without consent shall be void and, at the option of the Lessor, may terminate this Lease.
If you have a lease for a set term, like one year, you can sublet with or without your landlord's permission, unless they prohibit this in the written lease.
Subletting. In Texas, you are not allowed to rent your place to someone else without your landlord's permission. This law is in Section 91.005 of Texas Property Code. Some leases may allow it under certain conditions.
If your agreement doesn't say anything about subletting You don't need your landlord's permission but it's usually best to let them know. If they don't want you to sublet your home, your landlord can get a court order to end your tenancy, evict your subtenant and stop you from moving back in.
If you sublet your home when you're not allowed to, your landlord is likely to take action to evict you.
So first, in NYC a landlord cannot unreasonably deny a request to sublet. You must submit a written request at least 30 days in advance, and it must include things like who you'll be subletting to, why you're wanting to sublet, where you'll be during this period, etc...
Landlords restrict subletting because they want control of who's in their properties. You wanna sublet so you can get out of a lease, so your standards are somewhat reduced.

It must be written in strict adherence to property laws of the state where the property is located. Failing to do so can either render the lease invalid or unable to protect the landlord's property and interests from potential problem tenants.
Some states allow one person to sign the lease and then bring in unrelated roommates who do not sign the lease. Other states, like California and Texas, require all adult tenants to sign the lease. Those who do not are considered a guest of the lease signing tenant.
