The Residential Tranquility Amendment Act of 2025 amends the Residential Tranquility Act of 2010 to enhance protections against disturbances in residential areas. The bill prohibits the use of sound amplifying devices for demonstrations in residential zones between 7:00 p.m. and 9:00 a.m. It also makes it unlawful to leave unattended sound amplifying devices that emit sound while targeting a residence, and it establishes penalties for individuals who continue to target a residence after being instructed to cease by law enforcement. Additionally, the bill allows the Mayor and the Metropolitan Police Department to seize unattended sound amplifying devices used in violation of these provisions.

Furthermore, the bill introduces a new section that makes it illegal to knowingly throw or launch objects onto another person's residential property with the intent to cause fear, intimidation, or harassment. Violators of this provision may face fines or incarceration. The bill also amends the National Capital Revitalization and Self-Government Improvement Act of 1997 to specify that the term expiration date for a Council appointment to the Corrections Information Council shall be December 7th of the year in which the term expires.
