The bill amends Sections 11-106-3, 11-106-4, and 11-106-6 of the Code of Alabama 1975 to revise the definition of "military installation" and establish new requirements for constructing tall structures near these installations. Key changes include the requirement for individuals to obtain approval from local governments before commencing construction of any tall structure within two miles of a military installation. The bill also allows local governments to seek injunctive relief against any person who begins construction without the necessary approval. The definition of "military installation" is expanded to include any land area under the jurisdiction of the Department of Defense, and the term "tall structure" is defined as any building or structure exceeding 200 feet in height.

Additionally, the bill modifies the process for local governments to notify military installations of local impact issues and outlines the necessary documentation that must be provided by applicants for tall structures and wind energy facilities. This includes obtaining a "Determination of No Hazard to Air Navigation" from the Federal Aviation Administration or a written determination resolving any adverse impacts to military operations. The act is set to take effect on October 1, 2025.
