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 constructing any tall structure within two miles of a military installation. 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, with specific exclusions for certain types of structures.

Additionally, the bill allows local governments to seek injunctive relief against individuals who begin construction without the necessary approvals. It mandates that local governments notify military installations of any local impact issues and requires documentation from applicants regarding potential impacts on military operations before approving construction of tall structures or wind energy facilities. The act is set to take effect on October 1, 2025.
