Short Term Lease Addendum Template for the United States

A Short Term Lease Addendum is a legal modification document that allows you to temporarily alter specific terms of an existing lease agreement without replacing the entire contract. This addendum becomes part of your original lease and must be agreed upon by all parties involved, including landlords, tenants, and property managers when applicable.

When do you need this document?

You need a Short Term Lease Addendum when circumstances require temporary changes to your lease arrangement. Common situations include accommodating a temporary roommate or guest for an extended period, adjusting rent due to temporary property modifications or repairs, extending the lease for a few months while searching for new housing or tenants, or temporarily modifying pet policies for service animals or short-term pet care. This document is also essential when you need to adjust utility responsibilities temporarily, modify parking arrangements, or change occupancy limits for a specific period.

Key legal considerations

Your Short Term Lease Addendum must clearly reference the original lease agreement and specify which terms are being modified and for how long. All parties from the original lease must sign the addendum for it to be legally binding. The document should include specific start and end dates for the temporary modifications, ensuring clarity about when original lease terms resume. You must ensure that any modifications comply with your original lease's change procedures and don't violate any non-negotiable clauses. Additionally, consider how temporary changes might affect security deposits, insurance coverage, or liability issues. The addendum should address what happens if either party wants to terminate the temporary arrangement early and whether the modifications can be extended.

Legal requirements in United States

Under United States law, your Short Term Lease Addendum must comply with federal regulations including the Fair Housing Act, which prohibits discrimination based on protected classes such as race, color, religion, sex, national origin, familial status, and disability. If your property was built before 1978, you must maintain compliance with federal lead-based paint disclosure requirements even with temporary modifications. The Americans with Disabilities Act may require reasonable accommodations in your addendum terms. State landlord-tenant laws vary significantly and may impose specific requirements on lease modifications, including notice periods, permissible changes, and documentation standards. Some states have particular regulations governing short-term rental arrangements that could affect your addendum. You must also ensure that temporary modifications don't violate local zoning laws, housing codes, or homeowners association rules that may apply to your property.
