It depends but in this instance, the residential rental property will be considered fully depreciated after 27.5 year. Therefore you will not have any additional depreciation expense (unless you have made capital improvements that are still eligible for depreciation (see below).
According to the IRS, You must stop depreciating property when the total of your yearly depreciation deductions equals your cost or other basis of your property. For this purpose, your yearly depreciation deductions include any depreciation that you were allowed to claim, even if you did not claim it. See Basis of Depreciable Property .
Capital Improvements - Treat additions or improvements you make to your depreciable rental property as separate property items for depreciation purposes. For example, You own a residential rental house that you have been renting since 1986 and depreciating under ACRS. You built an addition onto the house and placed it in service in 2016. You must use MACRS for the addition. Under GDS, the addition is depreciated as residential rental property over 27.5 years
