Can I add the cost of fence, handicap ramp, new A/C and a new roof to the original cost of a gifted house?

[Coleen3 · Accepted solution]

Yes. You would add any improvement costs to the basis. Your basis for the gifted home is as follows:

If the FMV is equal to or greater than the donor's adjusted basis, your basis is the donor's adjusted basis at the time you received the gift. 

If the FMV of the property at the time of the gift is less than the donor's adjusted basis, your adjusted basis depends on whether you have a gain or loss when you dispose of the property.
