Residential Rental Property

The IRS published a comprehensive audit techniques guide used by examiners who evaluate cost segregation studies submitted by taxpayers. This guide helps taxpayers and study providers understand how to prepare audit-defensible studies.

Last updated by the IRS: February 2025.

H. Residential Rental Property

H.1. Planning and Examination Guidance

(1) Exhibit A is a matrix recommending the categorization and general depreciation system recovery period of various assets commonly associated with residential rental property. (For recovery periods under the § 168(g) alternative depreciation system, see § 168(g)(3) and Rev. Proc. 87-56, 1987-2 C.B. 674). If the taxpayer’s tax return position for these assets is consistent with the recommendations in Exhibit A, examiners should not make adjustments to categorization and recovery periods. If the taxpayer reports assets differently, then adjustments should be considered. See also the Cost Segregation Audit Techniques Guide. If you have any questions, please contact the Deductible and Capital Expenditures (DCE) Practice Network.

(2) This matrix, which is part of the Cost Segregation Audit Techniques Guide, is intended to provide direction to effectively utilize resources in the classification and examination of property used in the operation of residential rental property (RRP). RRP per § 168(e)(2)(A) is a building with 80% or more of the gross rental income from such building is rental income derived from dwelling units. A dwelling unit is defined as a house or apartment used to provide living accommodations in a building structure. General fact patterns specific to these properties have been considered in the classification of these assets and may not be applicable to other properties. Similarly, asset classification guidance issued for other industries is based on the general fact pattern for that industry and may not be applicable to RRP. For example, for asset classification of restaurant assets located within an apartment building, refer to the industry directive for restaurants. For examination techniques and historical background related to this issue, refer to the Cost Segregation Audit Techniques Guide. Per § 168(c), RRP is recovered over 27.5 years. A rental office/clubhouse building is non-residential real property (NRRP) (as defined in IRC § 168(e)(2)(B)), and is recovered over 39 years under § IRC 168(c). Asset Class 57.0 - Distributive Trades and Services applies to most of the § 1245 property used with RRP, which is recovered over 5 years. Property classified in the Asset Class 00.3 - Land Improvements are recovered over 15 years.
