Key legal question
Whether energy-saving and environmental protection expenses for a neglected property are deductible during the first five years after acquisition.
Extracted holding
Yes. The Dumont practice does not apply to energy-saving measures; 50% of such costs are deductible in the first five years even if the property was neglected.
Extracted reasoning
Energy-saving investments are expressly treated by law as deductible and are placed in a separate regulatory section from ordinary maintenance. The statute and ordinance do not make their deductibility dependent on whether the property was neglected.
