Such repairs and maintenance work as are required to keep it in sound condition may be made to a nonconforming building or structure, provided that no structural alterations shall be made except such as are required by law or ordinance. Except as otherwise provided elsewhere herein, the total structural repairs and alterations that may be made in a nonconforming building or structure shall not, during its life subsequent to the date of its becoming a nonconforming use, exceed 50% of its then appraised value for tax purposes at such time, unless such building or structure is changed to a conforming use.
