Sec. 17a.
(1) A nonconforming sign may continue to exist as long as it is not a destroyed, abandoned, discontinued, or prohibited sign. A nonconforming sign that has not displayed an advertising message for more than 1 year shall be considered an abandoned sign.
(2) A sign owner may perform customary maintenance and repair of a nonconforming sign. The annual cost of the customary maintenance and repair shall not exceed 40% of the replacement cost of a new sign structure constructed using equivalent materials and equipment.
(3) A sign owner may perform customary maintenance and repair of a nonconforming sign that is damaged as a result of storm, fire, or casualty. Customary maintenance and repair of a nonconforming sign that is damaged as a result of storm, fire, or casualty shall not exceed 60% of the replacement cost of a new sign structure constructed using equivalent materials and equipment. The 60% limitation in this subsection does not apply if the damage to the nonconforming sign is caused by vandalism or a negligent act of a person other than the sign owner.
(4) A nonconforming sign owner may not take any action that places this state out of compliance with federal statutes, published rules, regulations, or the federal-state agreement on outdoor advertising.
