Ludwig owned some land and a workshop building on the land. He acquired the land and building in 2014 for $600,000, of which $400,000 was allocable to the land and $200,000 allocable to the building. In 2018, there was a storm that damaged (but did not destroy) the roof of the workshop building. Ludwig spent $700 repairing the roof. Ludwig also spent $600 each year from 2015 to 2019 to paint the workshop. In 2019, Ludwig added a room to the building at a cost of $40,000. Through the end of 2019, Ludwig took depreciation deductions totaling $24,000. What is the adjusted basis of the workshop building at the beginning of 2020?
