Lessee shall not without prior written consent make any alterations, improvements, additions or utility installations in, on, or about the premises.

—The landlord is not responsible to the tenant under this section for conditions created or caused by the negligent or wrongful act or omission of the tenant, a member of the tenant’s family, or other person on the premises with the tenant’s consent.

They can't just cancel the contract on you without your consent. 

You would us it if adding, changing, or removing signatories, conditions, encompassed services or the description of premises (i.e. defining a garage or deck to be uniquely part of the premises covered by the lease).A letter of authorization / letter of consent is used to provide written proof of consent where the lease indicates an action is possible, but requires the landlords approval to occur.  

Matt, thanks for your response.My lease says this also: "Tenant shall not make any alterations or improvements to the Premises without Landlord's prior written consent."

This will generally require the notification (and perhaps consent) of your primary lender.  

This gives you the right to file claims directly to the contracotrs policy without the contractors consent.

If a landlord does seize a tenant's property, the tenant can sue the landlord.Also do you have any type of agreement that states you have the consent to automatically charge the rent to a credit card?

Without the consent of the current owner?

With an LLC I put in the operating agreements that ownership cannot be sold without unanimous consent to prevent bad surprises.
