taxmap/pubs/p946-023.htm#en_us_publink1000107526If your home is a personal-use single family residence and you begin to use part of your home as an office, depreciate that part of your home as nonresidential real property over 39 years (31.5 years if you began using it for business before May 13, 1993). However, if your home is an apartment in an apartment building that you own and the building is residential rental property as defined earlier under Which Property Class Applies Under GDS, depreciate the part used as an office as residential rental property over 27.5 years. See Publication 587 for a discussion of the tests you must meet to claim expenses, including depreciation, for the business use of your home.
taxmap/pubs/p946-023.htm#en_us_publink1000107527If you begin to rent a home that was your personal home before 1987, you depreciate it as residential rental property over 27.5 years.

taxmap/pubs/p946-023.htm#en_us_publink1000107529Property eligible for the shorter recovery periods are 3-, 5-, 7-, 10-, 15-, and 20-year property and nonresidential real property. You must use this property predominantly in the active conduct of a trade or business within an Indian reservation. The rental of real property that is located on an Indian reservation is treated as the active conduct of a trade or business within an Indian reservation.
The following property is not qualified property.
- Property used or located outside an Indian reservation on a regular basis, other than qualified infrastructure property.
- Property acquired directly or indirectly from a related person.
- Property placed in service for purposes of conducting or housing class I, II, or III gaming activities. These activities are defined in section 4 of the Indian Regulatory Act (25 U.S.C. 2703).

taxmap/pubs/p946-023.htm#en_us_publink1000107530Item (1) above does not apply to qualified infrastructure property located outside the reservation that is used to connect with qualified infrastructure property within the reservation.

- It is qualified property, as defined earlier, except that it is outside the reservation.
- It benefits the tribal infrastructure.
- It is available to the general public.
- It is placed in service in connection with the active conduct of a trade or business within a reservation.

taxmap/pubs/p946-023.htm#en_us_publink1000107532The term Indian reservation means a reservation as defined in section 3(d) of the Indian Financing Act of 1974 (25 U.S.C. 1452(d)) or section 4(10) of the Indian Child Welfare Act of 1978 (25 U.S.C. 1903(10)). Section 3(d) of the Indian Financing Act of 1974 defines reservation to include former Indian reservations in Oklahoma. For a definition of the term "former Indian reservations in Oklahoma," see Notice 98-45 in Internal Revenue Bulletin 1998-35.

The ADS recovery periods for property not listed above can be found in the tables in Appendix B.

taxmap/pubs/p946-023.htm#en_us_publink1000107534The ADS recovery period for any property leased under a lease agreement to a tax-exempt organization, governmental unit, or foreign person or entity (other than a partnership) cannot be less than 125% of the lease term.
taxmap/pubs/p946-023.htm#en_us_publink1000107535An addition or improvement you make to depreciable property is treated as separate depreciable property. See
How Do You Treat Repairs and Improvements in chapter 1 for a definition of improvements. Its property class and recovery period are the same as those that would apply to the original property if you had placed it in service at the same time you placed the addition or improvement in service. The recovery period begins on the later of the following dates.
- The date you place the addition or improvement in service.
- The date you place in service the property to which you made the addition or improvement.
 | If the improvement you make is qualified leasehold improvement property or qualified restaurant property (defined earlier under Which Property Class Applies Under GDS), the GDS recovery period is 15 years (39 years under ADS). |
taxmap/pubs/p946-023.htm#en_us_publink1000107537You own a rental home that you have been renting out since 1981. If you put an addition on the home and place the addition in service this year, you would use MACRS to figure your depreciation deduction for the addition. Under GDS, the property class for the addition is residential rental property and its recovery period is 27.5 years because the home to which the addition is made would be residential rental property if you had placed it in service this year.
