What Is a Shadow Vacancy?
In commercial real estate, a shadow vacancy is office space that is technically leased—but sits idle or underutilized. Think dimly lit floors, empty cubicles, or unused meeting rooms that still generate rent on paper but have no real occupants. These spaces don’t show up in standard vacancy reports, which means the market may appear tighter than it really is.
The problem? A property that’s “85% leased” may have only 60–65% actually in use. That hidden delta can distort rent trends, weaken renewal negotiations, and quietly erode property value.
How to Identify Shadow Vacancy
Since shadow space doesn’t show up in CoStar or quarterly leasing reports, savvy CRE brokers, landlords, and investors use the following cues to uncover it:
1. Tenant Utilization Trends
- Empty parking lots or dark office floors during business hours
- Reduced access logs or security badge swipes
- Wi-Fi activity or occupancy sensors (when available) showing under 50% usage
2. Sublease Listings
- A rise in partial sublease listings on LoopNet, Crexi, or CoStar
- Subtenants being offered large furnished spaces with little notice
3. Corporate Press & Downsizing News
- Headlines like “XYZ Corp announces remote-first policy” or “HQ moves to Texas”
- SEC filings hinting at downsizing or footprint consolidation
4. Broker & Ownership Intel
- Local brokers know which tenants are “ghosting” their leased space
- REITs and asset managers internally track shadow vacancy as part of NOI forecasting
The Hidden Cost of Shadow Vacancies
Shadow space quietly damages the foundation of CRE markets. Here’s how:
1. Inflated Occupancy Metrics
A building with a reported 15% vacancy might actually be closer to 25–30% when shadow space is factored in—limiting landlords’ leverage in lease negotiations.
2. Rent Erosion & Soft Renewals
Tenants nearing the end of their lease often:
- Downsize
- Exit entirely
- Push for big concessions (free rent, shorter terms, TI allowances)
3. Property Valuation Risk
Appraisers and lenders look at:
- Net Operating Income (NOI)
- Lease rollover schedules
- Stability metrics
If 30–40% of a building’s tenants aren’t actually occupying their space, it flags serious risk—leading to lower property values, tougher financing, and cap rate expansion.
