What Building Components Get Reclassified in a Cost Segregation Study?
Understanding Asset Reclassification
The core of every cost segregation study is the reclassification of building components from their default depreciation category (27.5 years for residential, 39 years for commercial) into shorter-lived categories of 5, 7, or 15 years. This reclassification is not arbitrary. It follows IRS guidelines, court rulings, and engineering standards that define which components have shorter useful lives or serve specific functions rather than the building's overall structure.
Understanding what gets reclassified helps property owners appreciate the value of a cost segregation study and explains why the first-year deductions can be so significant.
5-Year Property (Personal Property)
Five-year property, classified under MACRS as personal property, includes items that are not permanently attached to the building or that serve a specific function rather than a structural one. Common examples in residential rentals include carpeting and area rugs, vinyl and laminate flooring, appliances (refrigerators, ranges, dishwashers, microwaves, washers, and dryers), window treatments (blinds, shades, curtains), decorative lighting fixtures, removable cabinetry, bathroom accessories, and specialty electrical outlets serving specific equipment.
In furnished rentals or vacation properties, 5-year property also includes all furniture, electronics, entertainment systems, and decorative items. This category often represents the largest portion of reclassified assets in a residential cost segregation study.
7-Year Property
Seven-year property is less common in residential studies but can apply in certain situations. Items in this category include office furniture and equipment (for properties with a home office or business use), security systems, and certain specialty items. In commercial properties, 7-year property is more prevalent and includes items like filing systems, certain machinery, and specialized trade fixtures.
For most residential rental investors, the 5-year and 15-year categories represent the bulk of the reclassification benefit. However, a thorough engineering analysis will identify any 7-year components that apply.
15-Year Property (Land Improvements)
Fifteen-year property consists of land improvements, items that are attached to the land but are not part of the building structure. This category frequently includes driveways and parking areas, sidewalks and walkways, patios, decks, and porches, fencing and gates, landscaping (trees, shrubs, sod, irrigation systems), retaining walls, exterior lighting (pathway lights, parking lot lights), swimming pools and hot tubs, outdoor kitchens and fire pits, and site drainage systems.
Land improvements are often a significant component of the reclassification, particularly for properties with extensive outdoor amenities. A vacation rental with a pool, landscaped grounds, and a paved driveway may have $50,000 or more in 15-year property alone.
Why Engineering-Based Studies Matter
Accurately identifying and classifying these components requires engineering expertise. The IRS expects cost segregation studies to be based on detailed, component-level analysis rather than broad percentage estimates. Stratum's engineering-based approach examines every element of your property against the applicable IRS classification criteria, ensuring that every eligible component is reclassified and every reclassification is defensible in the event of an audit.
