Subject to subsection (b) of this section, the Mayor and City Council of Baltimore City or the governing body of a county or of a municipal corporation may grant a tax credit under this section against the county or municipal corporation property tax imposed on real property if: the homeowner is otherwise eligible for the credit allowed under § 9-105 of this title; the dwelling is: damaged or destroyed due to a natural disaster; and subsequently repaired or reconstructed; the dwelling is revalued after the dwelling is repaired or reconstructed; and as a result of the revaluation, the assessment of the dwelling exceeds the last assessment of the dwelling; and the homeowner claiming the credit had a legal interest in the dwelling at the time the dwelling was damaged or destroyed as described under item (2) of this subsection. A homeowner may receive a tax credit under this section only if the homeowner qualified and received a tax credit under § 9-109 of this title and is no longer receiving a tax credit under § 9-109 of this title. The amount of the property tax credit allowed under this section shall equal 50% of the property tax attributable to an increase in the assessment of the dwelling on revaluation under § 8-104(c)(1)(iii) of this article, including improvements, over the last assessment of the dwelling before the natural disaster, less the amount of any assessment on which a property tax credit under § 9-105 of this title has been authorized. A credit under this section may not be granted for more than 3 years. The Mayor and City Council of Baltimore City or the governing body of a county or municipal corporation may: establish procedures or requirements for the application, review, and approval of tax credits under this section; establish additional eligibility criteria such as age, income level, or assessment value; and notify the Department of any credits that have been granted under this section.
