Which item below is not added to the original basis to arrive at the adjusted basis of a home?

To determine the adjusted basis of a home, certain costs and improvements are added to the original basis, while other expenses are not. Typically, items such as routine maintenance and repair costs are not added to the original basis. Instead, they are considered current expenses and do not enhance the value of the home or prolong its life. Thus, these costs would not contribute to the adjusted basis.
