All good ideas but another one would be to make her sign a lease addendum. As an example this is one I used for a tenant who didn't want a double keyed deadbolt on her back door and wanted a large "doggy door" installed.
"In addition to the lease previously signed on February ____, 2015, the Landlord and Tenants agree as follows:
Tenants acknowledge the Texas Property Code may require a keyed dead bolt on each exterior door of the dwelling. Landlord intends to install and/or replace a keyed deadbolt on each exterior door of the dwelling. However, Tenants specifically and expressly request Landlord not install a keyed dead bolt on the back door of the dwelling. Tenants make this request with full knowledge of the Texas Property Code requirement, that the back door of the dwelling has a window above the dead bolt and in lieu of Landlord’s recommendation to install a double keyed dead bolt on the back door of the dwelling.
Tenants also request they be allowed to install a “doggy door” in the back door of the dwelling.
In consideration of Landlord foregoing the installation of a keyed dead bolt device on the back door of the dwelling and for consenting to the Tenants installing a “doggy door” in the back door of the dwelling at the Tenant’s own cost, Tenants hereby waive any and all rights and remedies they may have against the landlord for violations of the Texas Property Code and for any and all damages which the Tenants may suffer as a result, or in any way relating to, a keyed deadbolt not being installed on the back door of the dwelling or as a result, or in any way relating to, the allowance of a “doggy door” to be installed in the back door of the dwelling. These causes of action and damages waived include, but are not limited to negligence, conversion, theft, trespass, assault, or any other cause of action under Texas statutory or case law. TENANTS ALSO WAIVE ANY AND ALL CLAIMS AGAINST LANDLORD, ITS AGENTS AND ASSIGNS FOR GROSS NEGLIGENCE. Tenants further waive any subrogation claim any of their insurers may have for collection of any losses paid to the Tenants.
Finally, in further consideration of Landlord foregoing the installation of a keyed dead bolt device on the back door of the dwelling and for consenting to the Tenants installing a “doggy door” in the back door of the dwelling at the Tenant’s own cost, Tenants hereby agree to indemnify Landlord, its successors, agents and assigns for any and all claims, causes of action and damages which could be or are brought against Landlord, its successors, agents or assigns which are in any way related to the keyed dead bolt device on the back door of the dwelling not being installed or the installation of “doggy door” in the back door of the dwelling.
Tenants shall provide Landlord proof of payment in full for the installation of the “doggy door” in the back door of the dwelling.
Add a signature line and date – remember the lease should be entered into with the LLC as the landlord.
