(a) In addition to any other remedies or enforcement mechanisms available, upon the adoption of an ordinance finding that dwelling, building, or structure conditions of the character described in Code Section 41-2-7 exist within a county or municipality, the governing body of such county or municipality is authorized to adopt ordinances relating to the dwellings, buildings, or structures within such county or municipality which are unfit for human habitation or commercial, industrial, or business uses and not in compliance with applicable codes, which are vacant and being used in connection with the commission of drug crimes, or which constitute an endangerment to the public health or safety as a result of unsanitary or unsafe conditions. Such ordinances shall include at least the following provisions: (1) That it is the duty of the owner of every dwelling, building, structure, or property within the jurisdiction to construct and maintain such dwelling, building, structure, or property in conformance with applicable codes in force within the jurisdiction, or such ordinances which regulate and prohibit activities on property and which declare it to be a public nuisance to construct or maintain any dwelling, building, structure, or property in violation of such codes or ordinances; (2) That a public officer be designated or appointed to exercise the powers prescribed by the ordinances; (3) That whenever a request is filed with the public officer by a public authority or by at least five residents of the municipality or by five residents of the unincorporated area of the county if the property in question is located in the unincorporated area of the county charging that any dwelling, building, structure, or property is unfit for human habitation or for commercial, industrial, or business use and not in compliance with applicable codes; is vacant and being used in connection with the commission of drug crimes; or constitutes an endangerment to the public health or safety as a result of unsanitary or unsafe conditions, the public officer shall make an investigation or inspection of the specific dwelling, building, structure, or property. If the officer's investigation or inspection identifies that any dwelling, building, structure, or property is unfit for human habitation or for commercial, industrial, or business use and not in compliance with applicable codes; is vacant and being used in connection with the commission of drug crimes; or constitutes an endangerment to the public health or safety as a result of unsanitary or unsafe conditions, the public officer may issue a complaint in rem against the lot, tract, or parcel of real property on which such dwelling, building, or structure is situated or where such public health hazard or general nuisance exists and shall cause summons and a copy of the complaint to be served on the interested parties for such dwelling, building, or structure. The complaint shall identify the subject real property by appropriate street address and official tax map reference; identify the interested parties; state with particularity the factual basis for the action; and contain a statement of the action sought by the public officer to abate the alleged nuisance. The summons shall notify the interested parties that a hearing will be held before a court of competent jurisdiction as determined by Code Section 41-2-5 , at a date and time certain and at a place within the county or municipality where the property is located. Such hearing shall be held not less than 15 days nor more than 45 days after the filing of said complaint in the proper court. The interested parties shall have the right to file an answer to the complaint and to appear in person or by attorney and offer testimony at the time and place fixed for hearing; (4) That if, after such notice and hearing, the court determines that the dwelling, building, or structure in question is unfit for human habitation or is unfit for its current commercial, industrial, or business use and not in compliance with applicable codes; is vacant and being used in connection with the commission of drug crimes; or constitutes an endangerment to the public health or safety as a result of unsanitary or unsafe conditions, the court shall state in writing findings of fact in support of such determination and shall issue and cause to be served upon the interested parties that have answered the complaint or appeared at the hearing an order: (A) If the repair, alteration, or improvement of the said dwelling, building, or structure can be made at a reasonable cost in relation to the present value of the dwelling, building, or structure, requiring the owner, within the time specified in the order, to repair, alter, or improve such dwelling, building, or structure so as to bring it into full compliance with the applicable codes relevant to the cited violation and, if applicable, to secure the structure so that it cannot be used in connection with the commission of drug crimes; or (B) If the repair, alteration, or improvement of the said dwelling, building, or structure in order to bring it into full compliance with applicable codes relevant to the cited violations cannot be made at a reasonable cost in relation to the present value of the dwelling, building, or structure, requiring the owner, within the time specified in the order, to demolish and remove such dwelling, building, or structure and all debris from the property. For purposes of this Code section, the court shall make its determination of "reasonable cost in relation to the present value of the dwelling, building, or structure" without consideration of the value of the land on which the structure is situated; provided, however, that costs of the preparation necessary to repair, alter, or improve a structure may be considered. Income and financial status of the owner shall not be factor in the court's determination. The present value of the structure and the costs of repair, alteration, or improvement may be established by affidavits of real estate appraisers with a Georgia appraiser classification as provided in Chapter 39A of Title 43, qualified building contractors, or qualified building inspectors without actual testimony presented. Costs of repair, alteration, or improvement of the structure shall be the cost necessary to bring the structure into compliance with the applicable codes relevant to the cited violations in force in the jurisdiction; (5) That, if the owner fails to comply with an order to repair or demolish the dwelling, building, or structure, the public officer may cause such dwelling, building, or structure to be repaired, altered, or improved or to be vacated and closed or demolished. Such abatement action shall commence within 270 days after the expiration of time specified in the order for abatement by the owner. Any time during which such action is prohibited by a court order issued pursuant to Code Section 41-2-13 or any other equitable relief granted by a court of competent jurisdiction shall not be counted toward the 270 days in which such abatement action must commence. The public officer shall cause to be posted on the main entrance of the building, dwelling, or structure a placard with the following words: "This building is unfit for human habitation or commercial, industrial, or business use and does not comply with the applicable codes or has been ordered secured to prevent its use in connection with drug crimes or constitutes an endangerment to public health or safety as a result of unsanitary or unsafe conditions. The use or occupation of this building is prohibited and unlawful."; (6) If the public officer has the structure demolished, reasonable effort shall be made to salvage reusable materials for credit against the cost of demolition. The proceeds of any moneys received from the sale of salvaged materials shall be used or applied against the cost of the demolition and removal of the structure, and proper records shall be kept showing application of sales proceeds. Any such sale of salvaged materials may be made without the necessity of public advertisement and bid. The public officer and governing authority are relieved of any and all liability resulting from or occasioned by the sale of any such salvaged materials, including, without limitation, defects in such salvaged materials; and (7) That the amount of the cost of demolition, including all court costs, appraisal fees, administrative costs incurred by the county tax commissioner or municipal tax collector or city revenue officer, and all other costs necessarily associated with the abatement action, including restoration to grade of the real property after demolition, shall be a lien against the real property upon which such cost was incurred. (b) (1) The lien provided for in paragraph (7) of subsection (a) of this Code section shall attach to the real property upon the filing of a certified copy of the order requiring repair, closure, or demolition in the office of the clerk of superior court in the county where the real property is located and shall relate back to the date of the filing of the lis pendens notice required under subsection (c) of Code Section 41-2-12 . The clerk of superior court shall record and index such certified copy of the order in the deed records of the county and enter the lien on the general execution docket. The lien shall be superior to all other liens on the property, except liens for taxes to which the lien shall be inferior, and shall continue in force until paid. (2) Upon final determination of costs, fees, and expenses incurred in accordance with this chapter, the public officer responsible for enforcement actions in accordance with this chapter shall transmit to the appropriate county tax commissioner or municipal tax collector or city revenue officer a statement of the total amount due and secured by said lien, together with copies of all notices provided to interested parties. The statement of the public officer shall be transmitted within 90 days of completion of the repairs, demolition, or closure. It shall be the duty of the appropriate county tax commissioner or municipal tax collector or city revenue officer, who is responsible or whose duties include the collection of municipal taxes, to collect the amount of the lien using all methods available for collecting real property ad valorem taxes, including specifically Chapter 4 of Title 48; provided, however, that the limitation of Code Section 48-4-78 which requires 12 months of delinquency before commencing a tax foreclosure shall not apply. A county tax commissioner shall collect and enforce municipal liens imposed pursuant to this chapter in accordance with Code Section 48-5-359.1 . The county tax commissioner or municipal tax collector or city revenue officer shall remit the amount collected to the governing authority of the county or municipality whose lien is being collected. (3) Enforcement of liens pursuant to this Code section may be initiated at any time following receipt by the county tax commissioner or municipal tax collector or city revenue officer of the final determination of costs in accordance with this chapter. The unpaid lien amount shall bear interest and penalties from and after the date of final determination of costs in the same amount as applicable to interest and penalties on unpaid real property ad valorem taxes. An enforcement proceeding pursuant to Code Section 48-4-78 for delinquent ad valorem taxes may include all amounts due under this chapter. (4) The redemption amount in any enforcement proceeding pursuant to this Code section shall be the full amount of the costs as finally determined in accordance with this Code section together with interest, penalties, and costs incurred by the governing authority, county tax commissioner, municipal tax collector, or city revenue officer in the enforcement of such lien. Redemption of property from the lien may be made in accordance with the provisions of Code Sections 48-4-80 and 48-4-81 . (c) The governing authority may waive and release any such lien imposed on property upon the owner of such property entering into a contract with the county or municipality agreeing to a timetable for rehabilitation of the real property or the dwelling, building, or structure on the property and demonstrating the financial means to accomplish such rehabilitation. (d) Where the abatement action does not commence in the superior court, review of a court order requiring the repair, alteration, improvement, or demolition of a dwelling, building, or structure shall be a de novo proceeding in the superior court under Code Sections 5-3-4 and 5-3-5 . (e) In addition to the procedures and remedies in this chapter, a governing authority may provide by ordinance that designated public officers may issue citations for violations of state minimum standard codes, optional building, fire, life safety, and other codes adopted by ordinance, and conditions creating a public health hazard or general nuisance, and seek to enforce such citations in a court of competent jurisdiction prior to issuing a complaint in rem as provided in this Code section. (f) Nothing in this Code section shall be construed to impair or limit in any way the power of the county or municipality to define and declare nuisances and to cause their removal or abatement by summary proceedings or otherwise.
