It's property improvement that has to be capitalized and depreciated. Here's the IRS definition of a property improvement, translated to plain English so us common folks can comprehend it.
Property Improvement.
Property improvements
are expenses you incur that add value to the property. Expenses for this are
entered in the Assets/Depreciation section and depreciated over time. Property
improvements can be done at any time after your initial purchase of the
property. It does not matter if it was your residence or a rental at the time
of the improvement. It still adds value to the property.
To be classified as a
property improvement, two criteria must be met:
1) The improvement
must become "a material part of" the property. For example,
remodeling the bathroom, new cabinets or appliances in the kitchen. New carpet.
Replacing that old Central Air unit.
2) The improvement
must add "real" value to the property. In other words, when the property is appraised by a qualified,
certified, licensed property appraiser, he will appraise it at a higher value,
than he would have without the improvements.
