Cost segregation for coworking & flex office
Coworking is office turned inside out: the whole value proposition is reconfigurable fit-out, dense connectivity, and hospitality touches, and that is exactly the property that carries a short life. Where a plain office reclass is modest, a flex space with modular walls, heavy AV, a pantry kitchen, and phone-booth pods pushes into a 15–32% modeled range because so much of the build is designed to be moved and re-moved.

1What reclassifies in a coworking & flex office
In a coworking / flex office, cost segregation typically reclassifies 15–32% of depreciable basis out of the 39-year building shell into 5-, 7- and 15-year property. The components that recur:
| Component | Recovery period | Authority carried (with caveat) |
|---|---|---|
| Demountable & modular partitions — reconfigurable glass and panel walls, movable meeting rooms | 5-year | Partitions engineered to be relocated may qualify as personal property depending on their attachment and demountability. |
| Dense data & AV / low-voltage — floor boxes, WAPs, conference AV, digital signage, sound masking | 5-year | Communications and AV systems serving members' business use may be §1245 depending on whether they are dedicated to occupants rather than the building. |
| Cafe & pantry kitchens — coffee bars, undercounter equipment, member kitchenettes | 5-year | Kitchen and beverage equipment may qualify depending on whether it is business equipment rather than a building plumbing fixture. |
| Decorative feature finishes & lighting — accent walls, biophilic installations, statement pendants | 5-year | Décor finishes and non-general lighting may qualify depending on function and whether base building illumination exists independently. |
| Movable FF&E — desks, lounge seating, lockers, freestanding storage | 5-year | Freestanding furniture and equipment is generally §1245 personal property depending on whether it is unattached and readily movable. |
| Phone-booth pods & modular focus rooms — freestanding acoustic units | 5-year | Self-contained, relocatable pods may qualify depending on whether they are furniture-like units rather than constructed rooms. |
2Typical results and what drives the spread
Across standardized coworking / flex office configurations, the engine models an accelerated share of roughly 15–32%. Placement within the 15–32% modeled range rises with how much of the space is modular and AV- and hospitality-heavy versus conventional fixed office build-out. These are modeled ranges, not a promise for any specific building — see by the numbers.

6Is it worth it — break-even
Because so much of a coworking build is short-life fit-out and FF&E, the benefit generally clears a study fee at a lower basis than a plain office would require, and bonus depreciation on the eligible basis accelerates that further.
7Frequently asked questions
Why does coworking usually reclassify higher than a normal office?
The concept depends on reconfigurable, member-facing build-out — modular walls, pods, dense AV, and hospitality touches — which is the property most likely to carry a short life. A conventional office locks more cost into fixed partitions and base systems that stay 39-year.
Are the phone-booth pods really personal property?
Freestanding acoustic pods may qualify where they function as relocatable units rather than constructed rooms. The classification depends on whether they are set in place and connected loosely versus built into the structure.
We lease the floor and built it out ourselves — what can we depreciate?
You depreciate your own improvement basis. For a coworking operator that is often overwhelmingly short-life — partitions, AV, FF&E, and pantry equipment — so a tenant-owned build-out is frequently a strong candidate for a study.
Does the furniture count, or only the construction?
Freestanding furniture is generally §1245 personal property on its own short life. A study captures both the construction-embedded short-life items and the movable FF&E, as long as each is supported by how it is installed and used.
How does bonus depreciation interact with a coworking build?
Because a coworking build-out is short-life-heavy, bonus lets a large share of the basis be deducted faster in the placed-in-service year. That makes the timing benefit unusually pronounced compared with a shell-dominated property.
