Adjusted cost base is usually the cost of a property plus any expenses to acquire it, such as commissions and legal fees.
The cost of a capital property is its actual or deemed cost, depending on the type of property and how you acquired it. It also includes capital expenditures, such as the cost of additions and improvements to the property. You can’t add current expenses, such as maintenance and repair costs, to the cost base of a property.
A deemed cost, for example, would be if you acquired a property through gift or inheritance, and the cost would be the fair market value of the property at the time of acquisition.
