Vacancy Rate in Commercial Real Estate

The vacancy rate is the percentage of available square footage that is unleased in a commercial real estate market at any given time. A 10% office vacancy rate means 1 in 10 square feet of office space is vacant. Vacancy is a static snapshot—measured at a point in time—whereas absorption-rate-commercial is dynamic (net leasing per period). Together they tell whether a market is tightening or loosening, and they drive rent levels and tenant-improvement-allowance concessions.

Vacancy as a measure of landlord and tenant power

When a market has 3% office vacancy, landlords are in control. Every available space attracts multiple bidders; a landlord can raise rents aggressively, minimize tenant-improvement-allowance or concessions, and demand longer lease terms. A 3% vacant market typically shows annual rent growth of 3–8%.

At 8% vacancy, power is balanced. Tenants have some choice, but space still leases reasonably quickly. Rent growth slows to 1–2%, and landlords offer modest concessions ($20–30/sq ft TIA) to win deals.

At 15%+ vacancy, tenants control the deal. They can play landlords against each other, demand deep concessions ($50–100/sq ft TIA), negotiate flexible lease terms, and sometimes demand rent reductions. In such markets, rents stagnate or decline.

This threshold effect is why investors obsess over vacancy: it is the simplest predictor of rent direction. A market sliding from 5% to 8% vacancy over two quarters is sending a warning that rent growth will slow. A market dropping from 15% to 7% over a year signals rent acceleration ahead.

Historical vacancy benchmarks by sector

Office:

• Healthy range: 5–8% vacancy
• Tight: 3–5%
• Soft: 10–15%+
• Extreme: 20%+ (only in severe downturns or hollowed-out cities)

Pre-2020, major U.S. office markets averaged 6–8%. The 2008 financial crisis saw office vacancy spike to 15–17% in metros like Phoenix, Las Vegas, and Charlotte; recovery took 5–7 years. In 2020–2022, pandemic displacement pushed Manhattan office vacancy to 18%, San Francisco to 25%+, and suburban markets paradoxically to 6–8% as companies fled downtown.

Retail:

• Healthy: 5–6%
• Soft: 8–12%
• Severe: 15%+

Retail is structurally challenged: e-commerce has eroded demand for physical stores. Regional mall vacancies have climbed to 15–20%; enclosed shopping centres are, in many markets, economically obsolete. Neighbourhood retail and single-tenant locations remain healthier (6–10% vacancy) but rarely enjoy the tight 3–5% environments that office once did.

Industrial:

• Tight: 2–4%
• Healthy: 4–6%
• Soft: 8%+

Industrial is the star performer. E-commerce demand for logistics and distribution space has kept industrial vacancy tight—many prime markets have 2–4% vacancy, sometimes lower. Rents in logistics parks have risen 5–10% annually during the past decade.

Multifamily:

• Healthy: 5–7% (apartments)
• Tight: 2–3%
• Soft: 8–10%+

Apartment vacancy is typically measured by unit, not square footage. Healthy supply-demand keeps most growing metros at 5–6%, supporting 2–4% annual rent growth. Oversupplied Sunbelt metros (Austin, Phoenix, Nashville during 2022–2024) saw multifamily vacancy spike to 8–10% as developers flooded markets, pressuring rents.

Vacancy and the lease cycle

A vacant space doesn’t sit empty forever. When a lease expires, the landlord has days or weeks to re-lease before that space contributes to the vacancy count. For major office buildings or retail anchors, a 60–90 day lag between lease expiry and new tenant move-in is typical. During that gap, space is counted as vacant.

In a tight market with 4% overall vacancy but 2% “leased but not yet occupied,” the effective vacancy (space truly empty) is only 2%—and rents are accelerating. In a soft market with 12% vacancy and 4% “leased but not yet occupied,” the effective vacancy is 16% when accounting for pipeline, and rents are under pressure.

This is why market researchers distinguish between “available” space (vacant + being vacated soon but not yet empty) and truly vacant space. The gap between the two can matter to investment timing.

Relationship between vacancy and absorption-rate-commercial

Vacancy changes based on absorption (net leasing per period) and new construction:

Vacancy change = New supply built – Net absorption

If a market builds 5 million sq ft in a year but absorbs only 3 million, vacancy rises (by roughly 2 million sq ft). If absorption is 6 million and new supply is 3 million, vacancy falls sharply.

A market can have high vacancy but declining vacancy (positive absorption outpacing new supply), signalling an inflection point—rents are about to rise. Manhattan office in 2022 had 18% vacancy but improving absorption-rate-commercial quarter-to-quarter, suggesting tightening ahead. Conversely, a market with 8% vacancy but negative absorption-rate-commercial (more departures than new leases) is loosening and rents will soften—a cautionary signal.

Vacancy in commercial-mortgage-backed-securities underwriting

When a commercial-mortgage-backed-securities deal pools mortgages on shopping centres, office towers, and industrial parks, underwriters stress-test loan performance under different vacancy scenarios. A CMBS prospectus might assume 8% market vacancy, but investors model: “What if vacancy rises to 12%? What if absorption-rate-commercial turns negative?”

A property with 90% occupied space in a market with 10% average vacancy is performing above average and is safer. A property at 85% occupied in a market with 5% average vacancy is underperforming and is riskier. CMBS investors compare property-level occupancy to market vacancy to assess relative risk.

Pooled CMBS mortgages typically benefit from geographic and sectoral diversity: some backing office in one city, some backing industrial in another, some retail. If all legs of the pool are exposed to rising vacancy simultaneously—a recession hitting all property types—the CMBS tranches absorb losses quickly. Diversified pools are more resilient.

Vacancy volatility during economic cycles

Vacancy is cyclical and sometimes violent. The 2001 recession saw office vacancy jump from 5% to 13% in a year as dot-com layoffs and telecom bankruptcies cascaded. Recovery was slow; vacancy stayed above 10% for 4 years.

The 2008 financial crisis saw office vacancy spike from 7% to 17% by 2009–2010, with industrial and retail not far behind. The Great Recession was the nadir; many markets took 6–8 years to return to pre-crisis vacancy levels.

Conversely, the 2015–2019 expansion was benign: low absorption-rate-commercial, modest new supply, and stable 6–8% office vacancy across major metros. Rents rose steadily, and tenant-improvement-allowance concessions tightened.

The 2020 pandemic shock was sector-specific: office vacancy spiked sharply in major CBDs, while industrial and suburban office remained tight. By 2023, the pattern was clear—office and retail vacancy elevated, industrial tight—reflecting structural shifts (work-from-home, e-commerce) rather than a business cycle trough.

Using vacancy to forecast rent

A simple heuristic: every 1% increase in vacancy typically correlates with 0.5–1.5% downward rent pressure in the following year, depending on sector and supply pipeline. Conversely, every 1% decline in vacancy (tightening) supports 1–3% annual rent growth.

This relationship is not mechanical—a market can post rising vacancy while rents hold or grow slightly if new supply is sparse—but it holds broadly. Vacancy is the strongest single-factor predictor of rent direction, which is why property owners, real-estate-investment-trust managers, and mortgage lenders treat vacancy as the front-line leading indicator of market health.
