Replacements of all the gutters and soffit of your residential rental property:
- Are generally restorations to your building property because they're replacements of major components or substantial structural parts of the building structure. As a result, these replacements are capital improvements to the residential rental property.
- Are in the same class of property as the residential rental property to which they're attached.
- Are generally depreciated over a recovery period of 27.5 years using the straight line method of depreciation and a mid-month convention as residential rental property.
