(a) Except as otherwise provided in subsection (c) of this Code section, a municipality or county shall have the right to acquire, by exercise of the power of eminent domain, any real property which it may deem necessary for its purposes under this chapter, after the adoption by it of a resolution declaring that the acquisition of the real property described therein is necessary for such purposes. A municipality or county may exercise the power of eminent domain in the manner provided in Title 22; or it may exercise the power of eminent domain in the manner provided by any other applicable statutory provisions for the exercise of the power of eminent domain. Property already devoted to a public use may be acquired, provided that no real property belonging to the municipality, the county, the state, or any political subdivision thereof may be acquired without its consent.

(b) Whenever condemnation proceedings are instituted and carried on by a municipality or county in accordance with subsection (a) of this Code section or through any other method of condemnation provided by law, upon the payment by the municipality or county seeking condemnation of the amount of the award and final judgment on appeal the municipality or county shall become vested with a fee simple indefeasible title to the property to which the condemnation proceedings relate. Such payment may be offset in whole or in part by the amount of any municipal or county tax liens on the condemned property and by any existing special assessments tax liens on the condemned property, including without limitation education or special district taxes collected by the municipality or county; provided, however, that any such setoff shall be subject to any existing tax liens having higher priority pursuant to Code Section 48-2-56 and to the interest in the condemned property of any known beneficiary of a year's support pursuant to Code Section 53-5-2 of the "Pre-1998 Probate Code," if applicable, or Code Sections 53-3-1, 53-3-2, 53-3-4, 53-3-5, and 53-3-7 of the "Revised Probate Code of 1998"; provided, further, that where the condemned property is subject to a valid deed to secure debt, such setoff shall only be allowed for tax liens which arose as a result of an assessment against such property. It is declared to be necessary, to enable such municipalities and counties to exercise their powers under this Code section, that upon the condemnation proceedings being had, the municipalities and counties shall become vested with fee simple indefeasible title to the property involved in the proceedings.

(c) Unless the property is to be acquired for the purpose of devoting it to a public use, a municipality or county may not acquire real property through the exercise of the power of eminent domain pursuant to subsection (a) of this Code section until the following conditions and requirements have been met:

(1) The municipality or county which adopted the urban redevelopment plan has approved a resolution authorizing the exercise of the power of eminent domain by the agency to acquire the property;

(2) The municipality or county shall, in writing, notify the owner of the real property proposed to be acquired of the planned rehabilitation of the property as set forth in the urban redevelopment plan for the urban redevelopment area wherein the property is located; (3) Within 30 days after being so notified, the owner of the property shall have the option of notifying the municipality or county, in writing, of his willingness and intention to rehabilitate and maintain the property in accordance with the urban redevelopment plan. In the event of multiple ownership of the property, unanimous agreement by the owners shall be required; and the failure of any one owner to notify the municipality or county, within the time limitation specified in this paragraph, of his willingness and intention to rehabilitate and maintain the property in accordance with the urban redevelopment plan shall be deemed to be a failure to exercise the option provided in this paragraph; and

(4) The owner of the property may execute an agreement with the municipality or county to rehabilitate the property in accordance with the urban redevelopment plan. Any such agreement shall be as the municipality or county deems necessary and appropriate as to form and content; in connection therewith, the municipality or county shall have the right to require sufficient performance, payment, and completion bonds. In the event that any such owner, at any time, fails to comply with or defaults in the performance of the provisions of the agreement, such property shall no longer be subject to the agreement, the option provided by paragraph (3) of this subsection shall no longer apply, and the property may be acquired by the municipality or county by purchase or through the exercise of the power of eminent domain. In the alternative, the municipality or county may either specifically enforce the agreement, exercise any rights under any bonds which may have been required, and obtain any other legal or equitable relief as may be available to the municipality or county or, if the owner fails to exercise the option to rehabilitate the property or defaults on the agreement to rehabilitate the property, the municipality or county may implement those portions of the urban development plan with respect to such property to the extent the municipality or county deems necessary and the costs of implementing such plan shall be a lien against the property enforceable in the same manner as tax liens.
