Cost Segregation by Property Type

What a study typically reclassifies for 24 building types, and a dedicated guide for each: asset breakdowns, worked examples, hypothetical case studies, and the strategies that pair with the deduction.

Quick answer

Cost segregation results vary enormously by building type: Engineered Tax Services reports typical depreciation acceleration from 18-30% on warehouses and research facilities up to 60-100% on mobile home parks, gas stations, and car washes. Pick your property type below for the component breakdown, worked example, and pairing strategies specific to it.

Ranges are Engineered Tax Services' published typical figures, shown as the share of depreciable basis moved to 5-, 7-, and 15-year lives. Your property's result depends on construction, land allocation, and the engineering takeoff.

How to Read the Ranges

Three patterns explain almost the whole table.

Site-dominant properties top the table. Mobile home parks, gas stations, car washes, and drive-up self-storage are mostly 15-year land improvements (paving, pads, utility infrastructure, fencing) with little long-life building, so 60% and up is normal. Gas stations add a statutory gift: a qualifying retail motor fuels outlet building is itself 15-year property.

Equipment-dense buildings fill the middle. Medical offices, restaurants, hotels, grocery stores, and banks carry heavy 5-year pools (clinical systems, kitchens, FF&E, refrigeration, security equipment) inside conventional structures, landing them in the 25-55% band.

Plain shells sit at the bottom, honestly. Warehouses and research facilities reclassify 20-30% because most of their cost is structure (or building-serving lab air). At industrial scale the absolute dollars still justify studies; the percentage just will not flatter anyone.

The number that matters is not on this table

Usability is. A deduction that suspends as a passive loss helps eventually; the same deduction timed into a year with REPS, a qualifying short-term rental, material participation, or a big gain helps now. Every guide below pairs the property analysis with the strategies that make the loss land, and the full mechanics live in our complete cost segregation guide.

Every guide covers the same ground for its building type: which components move to 5- and 15-year lives and why, a worked dollar example with 100% bonus depreciation, a hypothetical case study, the other tax strategies that fit that owner (entity structure, monthly accounting, QIP, energy deductions), and how the study gets done. The engineering runs through Engineered Tax Services, and Taxstra implements the results on the return, including Form 3115 look-back studies for property you already own.

Frequently Asked Questions

Site-heavy and equipment-dense properties lead the table: mobile home parks (60-100% typical acceleration per Engineered Tax Services), gas stations (50-100%), car washes (75-100%), and self-storage (18-90%) at the top, with medical offices (30-55%), theme parks (30-68%), and golf courses (28-60%) close behind. Plain warehouses and research facilities (20-30%) sit at the bottom, though large absolute basis can still make those studies worthwhile.
