8 Markets Where Vacancy Risk Is Growing

Key Takeaways

• Vacancy risk is rising in coastal office hubs like San Francisco and New York City, especially across Class B/C buildings and expanding sublease inventory.
• Silicon Valley remains highly sensitive to tech layoffs, which can quickly push more space onto the market.
• Sun Belt rentals (Charlotte, Houston, Las Vegas) are absorbing a 2024–2025 supply wave, while certain retail, industrial, and tourism markets also warrant closer monitoring.

Where Vacancy Pressure Is Building Fast

Watch vacancy risk rise in San Francisco and New York City, where Class B and C offices face leaks, high costs, and growing sublease space. Track Silicon Valley tech space too, because layoffs can flood listings fast.

In Sun Belt rentals, Charlotte, Houston, and Las Vegas feel the 2024-2025 supply wave and heavier concessions.

Add mall-heavy retail zones, big-box industrial corridors, and seasonal tourism towns to your watchlist.

Keep going to see the five metrics.

How to Spot Vacancy Risk Fast (5 Metrics)

How do you spot vacancy risk before it shows up in your bank account?

You track five fast metrics, then you act while there’s still time. Vacancy risk directly influences financing terms and lender confidence.

1) Vacancy rate: vacant units divided by total units, times 100.

2) Breakeven Occupancy gap: compare your breakeven to local history; a higher breakeven than the market raises risk.

3) Direct plus sublease vacancy: empty landlord space and tenant listed space together show true slack. In NYC offices, vacancy reached 19.2% alongside 209M sq ft of sublease space, underscoring how tenant listings can magnify apparent availability.

4) Forward supply: watch availability rates and space under construction, since new deliveries can flood choices.

5) Cash quality: monitor Collection Rates and turnover speed.

Slow fills, more concessions, and missed rent warn you early.

If net absorption turns negative in your metro, demand is shrinking.

Downtown Office Vacancy Risk: Class B/C Stress

While trophy towers still draw attention, the real vacancy pain often sits in downtown Class B and C offices.

You see it in places like San Francisco, where downtown vacancy tops 22%, and in New York City, where CBD vacancy reaches 30.9%. In Manhattan alone, 17 million sq ft of office space was handed back to landlords over the past year.

When tenants compare old lobbies and slow elevators to Class A perks, they often walk.

You can’t fix this with discounts alone.

Asking rents are down 8% since the pandemic, but costs stay, so owners feel squeezed.

Deferred maintenance then shows up as leaks, outdated HVAC, and tired common areas, and that pushes more tenants out.

To protect value, you focus on Tenant retention.

You upgrade what matters most, simplify leases, and communicate a plan so tenants believe downtown can work again.

Tech-Hub Vacancy Risk: Sublease Space and Layoffs

Because tech moves fast, your office risk in a tech hub can change in a single quarter when growth turns into caution.

Tech now drives 16.5% of leasing, and AI firms have taken millions of square feet in places like San Francisco, Silicon Valley, and New York, so momentum can look safe.

Even as office risk rises, Seattle’s recent $425M multifamily sale shows investors still back tech-driven metros with resilient rental fundamentals.

But flexible space and smaller average deals mean tenants can pull back fast.

When layoffs hit, you can face a Sublease Flood, especially in B-quality buildings as bigger firms right-size and push space back to the market.

If a Talent Exodus follows, premium submarkets near universities that charge 10% or more above city averages can feel the drop first.

Protect yourself by stress-testing rents, tracking net absorption, and favoring resilient buildings today.

Sun Belt Multifamily Vacancy Risk: New Supply Wave

Office markets can flip fast, but apartments in the Sun Belt can shift just as quickly when new buildings hit all at once.

You’re watching a 2024-2025 completion glut that came from the low-rate boom, even as national vacancy touched 7.3% in December.

In many Sun Belt metros, you’ll see operators chase occupancy with concessions, not rent.

Amenity Saturation makes one more pool or coworking room feel less special, and the Financing Crunch limits who can buy and reposition assets.

1. Track deliveries in Charlotte, Houston, and Las Vegas.

In Charlotte, the office vacancy rate reached 21.8% in Q1 2025, a 21.8% vacancy rate that can reshape where redevelopment dollars flow.

2. Compare effective rents, not just asking rents.

3. Stress-test cash flow for 18-24 months of burnoff.

4. Remember starts fell hard, so relief can arrive by 2027.

If demand holds, vacancy should ease soon.

Retail Vacancy Risk: Anchor Closures and Trade-Area Drift

Even if retail vacancy still sits near historic lows, you can feel risk building when a big anchor goes dark and the whole center loses its pull.

That Anchor Attrition cuts foot traffic and makes in-line tenants question their next renewal.

Closures are still manageable, and service, food, and experience users often backfill fast, sometimes in under seven months.

But store rationalization keeps vacancy nudging up into 2026, with a peak still expected under 4.4 percent.

In U.S., watch leasing speed and tenant mix.

Your bigger worry is Trade Drift.

Shoppers concentrate in open-air, grocery-anchored, high-traffic suburbs, while weaker trade areas thin out and slide toward redevelopment.

With over 192 malls now in the process of conversion, some empty anchors are increasingly a trigger for mixed-use redevelopment into housing rather than a short-term leasing gap.

Add tariff driven inflation and value seeking, and discretionary tenants hesitate, so every empty anchor matters more.

Industrial Vacancy Risk: Post-Boom Warehouse Overbuild

Retail vacancy risk often starts with one dark anchor, but industrial risk shows up in a different way: too many new boxes rising at once.

By late 2025, you faced 1.5 billion square feet available nationwide across the U.S. today and 7.5% vacancy, up from 4% in 2023.

Big-box space takes the hit, with vacancy near 11%, while small-bay stays tighter.

When tenants chase newer, automation-ready buildings, older warehouses sit empty, and rent growth feels flat.

1. Track 2026 forecasts: vacancy could reach 7.8%, or 9% in a rough economy.
2. Favor build-to-suit and right-size footprints over speculative bets.
3. Plan adaptive reuse for obsolete sites, from light manufacturing to final-mile bays.
4. Use land banking to wait for demand, not chase the boom.

Tourism-Market Vacancy Risk: Seasonal Demand Whiplash

Because travel demand now shifts by week and season, you can see vacancy risk creep in even when a market looks busy on paper. In many U.S. beach and mountain towns, mid-week stays rise as remote workers travel Sunday to Thursday, then drop.

Shoulder seasons look stronger, yet Shoulder season volatility can still crack your forecast. If you price for previous year’s peak, you’ll feel gaps from shorter, cautious trips.

Travelers dodge crowds and test secondary markets, while mature hubs saturate. Longer booking lead times can help you plan, but new short-term rental rules can tighten supply fast. You cut risk when you market year-round and reset rates every week. Stay curious, watch the calendar daily, and build a steady off-peak base for yourself.

University-Town Vacancy Risk: Enrollment and Housing Shifts

While campus headlines talk about growth, you can still feel vacancy risk rise fast in a university town when housing shifts under your feet.

Enrollment across 184 U.S. schools rose 1.8%, and fall 2025 occupancy hit 95.1%, but results vary. New apartments pushed U.S. vacancies higher since 2021.

Watch how Preleasing Dynamics show strain when January 2026 preleasing hits 52.3% overall and 39 schools sit under 30%.

Factor On campus Exclusion too, because dorm residents like San Jose's 28,150 students won't appear in household counts.

1. Track beds underway in Memphis, Virginia, Boulder, and Berkeley.
2. Compare rent per bed, near $915, with 0.2% growth.
3. Check local vacancy, like Santa Clara at 4.6%.
4. Sign earlier, so new supply doesn't box you in.

Frequently Asked Questions

How Do Interest Rates Change Vacancy Risk for Long-Lease Properties?

Like a tide reshaping shorelines, higher rates keep buyers renting, so you cut vacancy risk on long leases; but rising capitalization rate and easing yield compression can deter renewals and financing, raising future vacancy exposure.

What Lease Clauses Best Protect Landlords During Vacancy Spikes?

You’ll protect yourself with clear renewal/holdover terms, joint-and-several rent liability, late fees, and Rent Acceleration for default. Add Sublet Restrictions, strict occupancy/use rules, maintenance reporting duties, and security-deposit, severability, and rent-acceptance clauses.

How Should Lenders Adjust Underwriting When Vacancy Risk Rises?

You tighten underwriting like reefing sails before a squall: run deeper stress testing on rent, rollover, and exits; demand stronger DSCR, scrutinize tenant mix and climate exposure, and price conservatively with higher reserves for contingencies.

Which Insurance Coverages Help Offset Vacancy-Related Income Loss?

You’ll offset vacancy-related income loss with Business Interruption coverage when a covered peril halts operations, and Rent Guarantee coverage for missed lease payments. Add a vacancy permit so you don’t lose coverage after 60 days.

What Are Early Legal Warning Signs of Tenant Distress Before Vacancy?

Like storm clouds over Troy, you spot trouble early when tenants trigger bankruptcy filings, request rent waivers, or contest charges. You’ll also see certified-demand letters ignored, repeated lease-breach complaints, and eviction notices served or threatened.

Assessment

You can’t stop every vacancy spike, but you can see it coming and act. Watch supply, job churn, sublease listings, rent cuts, and days-on-market. Then adjust your plan before the numbers force your hand.

Picture a Class B office owner in downtown St. Louis who ignored rising subleases. One key tenant left, and the lobby went quiet. You can choose differently.

Call tenants early, refresh the space, price smart, and build reserves. Those moves won’t eliminate risk, but they’ll soften the hit when demand shifts. Protect the cash flow—and you’ll sleep better at night, too.
