§ 12-1. Applicability of exemption.

An improvement to any real property used solely for residential purposes as a one-, two-, or three-family residence shall be exempt from taxation to the extent of any increase in value attributable to such improvement if the improvement is used for the purpose of facilitating and accommodating the use and accessibility of said real property by a resident owner of the real property who is physically disabled or a member of the resident owner's household who is physically disabled, if such member resides in the real property. Such exemption shall apply to improvements constructed prior to and subsequent to the effective date of this chapter.
