Quarterly market reports from CBRE and JLL are written for institutional investors. Here is what the headline number translates to for a business owner signing a lease in the next six months.
Denver’s commercial real estate brokers have been quoting roughly the same figure for several quarters: about one in four square feet of office space in the metro sits empty. That number shows up in Denver Business Journal headlines and institutional press releases, then stops doing useful work for the people who actually need it — the founder renewing her lease on 3,000 square feet in LoDo, the professional services firm shopping RiNo for the first time, the DTC company that just shed headcount and is renegotiating its footprint.
The vacancy rate is real information. It just hasn’t been translated into terms that matter at the negotiating table.
What a 25 Percent Vacancy Rate Means for the Landlord Across the Table
Start with the landlord’s balance sheet, because that’s the engine driving your position.
At 25 percent vacancy, one in four rentable square feet generates zero revenue. The building owner is still carrying full debt service, property taxes, HVAC, security, and insurance on space with no tenant paying into those costs. Concessions are not gifts a generous landlord extends to a lucky tenant. They are the price of removing a cash-flow hole from a portfolio. When you ask for months of free rent or a substantial tenant improvement allowance, you’re not being aggressive — you’re responding rationally to conditions the landlord’s own numbers already reflect.
Denver has been running in the 22–26 percent vacancy range across 2024–2025, above the national office vacancy rate of roughly 19–20 percent by Moody’s and CBRE measures. That gap matters. Denver is softer than the national average, which means tenant leverage here is above-average too. If you’ve been treating them as roughly equivalent, you’ve likely been leaving money on the table.
The concept that does the most practical work in any negotiation is the spread between asking rent and effective rent. Asking rent is what appears on the listing — say, a posted rate for a 4,000-square-foot floor in a LoDo mid-rise. Effective rent is what you actually pay once the full concession package is factored in: free rent periods, TI allowances amortized over the lease term, parking abatements. That spread is your starting position, and it should drive every counteroffer.
Not All Vacancy Is Created Equal
The 25 percent figure is a metro-wide average, which masks real variation. Where your building sits matters as much as overall market conditions. Describing “Denver office” as a single market is almost as useful as describing “Denver weather.”
The submarket picture below reflects recent CBRE and JLL Denver reporting. Verify current vacancy rates and asking-versus-effective rent spreads against the most recent CBRE Denver Market View or JLL Denver Office Insight before anchoring any offer.
LoDo / CBD. Class A asking rents have been in the $28–$38 per square foot range (full-service gross), with effective rents meaningfully lower after concessions. The 16th Street Mall reconstruction, completed in phases through 2023–2024, disrupted foot traffic and made certain corridors harder to lease than raw vacancy figures suggest. Landlords in those blocks have been more flexible than they’d probably like to admit.
RiNo / River North. Asking rents run roughly $22–$32 per square foot. RiNo drew marketing agencies, tech startups, and design firms during its 2019–2022 run; remote work contraction has softened that demand considerably. The tenant profile skews toward smaller businesses on shorter terms, so the sublease shadow market here is thinner than in DTC — worth knowing if you’re hunting for sublease space specifically.
Denver Tech Center / Greenwood Village. DTC likely carries the highest vacancy of any major submarket, driven by corporate rightsizing and significant sublease inventory from energy and telecom consolidations. If you’re shopping DTC, you’re entering negotiations from the strongest position in the metro. Free parking is a structural advantage over downtown — a real cost difference for car-dependent teams. That said, the walk from RTD light rail stations to most DTC buildings is substantial, which has softened demand from tenants trying to recruit from central Denver. Worth thinking through before you commit.
Cherry Creek. Vacancy here is tight relative to the broader market. The tenant mix skews toward boutique professional services, medical, and financial practices, and there’s limited institutional product. If a Cherry Creek address matters to your business identity or client base, expect a thinner concession menu and a firmer landlord. You can still negotiate — just don’t anchor your expectations to what you’d get in DTC.
The Concession Menu Denver Landlords Are Actually Offering Right Now
Free Rent
Free rent is the most common concession in a soft market. On a five-year deal in Denver’s high-vacancy submarkets, 6–12 months is realistic depending on the building, submarket, and your credit profile. Longer deals unlock larger packages.
Front-loaded free rent — months one through however many, rent-free at commencement — is better for your cash flow than free rent split across anniversary periods. Don’t let a landlord bury your free rent in years four and five. That’s not the same thing, and any broker who lets it slide without flagging it is not doing their job.
Tenant Improvement Allowances
TI allowances are landlord-funded contributions toward buildout costs, paid per square foot against construction invoices. For seven-to-ten-year deals in Class A space in Denver’s softer submarkets, allowances in the $60–$100 per square foot range have been achievable. Shorter terms and Class B buildings produce lower figures.
The critical qualifier: get a contractor or space planner to price your actual buildout scope before you settle on a number. If the TI falls short of your real construction cost, you’re out-of-pocket the difference — and that difference belongs in your effective rent calculation. It surprises a lot of tenants who skipped this step.
Parking
Parking is an underappreciated line item and varies sharply by submarket. In DTC, where commuters skew car-dependent and structured parking is more abundant, free parking has become increasingly standard in competitive deals. If you’re negotiating there and parking isn’t in the first offer, ask for it. In LoDo, where paid parking is a meaningful monthly cost, push for a discounted rate or at least a first-year abatement.
Moving Allowances and Operating Expense Exposure
Direct moving allowances — paid against invoices — aren’t universal, but in deals where landlords are competing hard for a specific tenant, they’re available. It costs nothing to include one in your initial ask.
On operating expenses: if you’re considering Class B or C space in Denver, pay attention to one item before you sign anything. Denver’s Energize Denver building performance ordinance requires buildings above a certain size to meet escalating energy benchmarks, with compliance deadlines that create real capital expenditure pressure for older properties. In triple-net and modified gross leases, landlord capital costs tied to Energize Denver compliance can flow to tenants through operating expense pass-throughs or CAM reconciliations. This is already showing up in reconciliation statements for tenants who didn’t ask the right questions upfront.
Ask specifically whether any building performance-related capital work is planned or underway. Negotiate an operating expense cap — typically 3 to 5 percent annually on controllable expenses — and get clarity in the lease on whether Energize Denver compliance costs are capital expenses (landlord’s problem) or operating pass-throughs (your problem). Buildings that haven’t yet met their benchmarks carry an embedded liability that a tenant in year three of a five-year lease may end up funding.
The Sublease Shadow Market
There’s a parallel market most small and mid-sized businesses never explore. Denver’s tech and energy sector contractions have deposited a significant inventory of sublease space onto the market, primarily in DTC and portions of LoDo. A corporation that signed a ten-year lease in 2019 and now needs a fraction of that space is motivated to find a subtenant — not because it wants to, but because it’s paying rent on every vacant square foot regardless. That’s your leverage.
Sublease rents in a market like this typically run well below comparable direct lease asking rates in the same building. But sublease agreements are structurally different from direct leases, and the differences matter.
Your maximum term is whatever remains on the master lease. If the master tenant has four years left, you get four years — no matter how much longer you’d like to stay. You’re taking the space roughly as the prior tenant left it, which can be an advantage (finished, furnished, move-in ready) or a constraint (the layout doesn’t fit and you can’t easily change it). If the sublandlord defaults on its master lease, your sublease is at risk, so review the master tenant’s financial position before signing. The building landlord must also consent to the sublease — most master leases require it, and you should add time to your transaction schedule accordingly.
A sublease makes strong sense when your runway is defined, cost sensitivity is high, and you need built-out space quickly within the sublandlord’s remaining term. It makes less sense when you need a custom buildout, term certainty beyond what the master lease provides, or a direct relationship with the building landlord for the long haul. DTC has the heaviest sublease inventory in the metro. If you’re shopping that submarket, have your broker pull sublease availabilities alongside direct listings before you narrow your search.
Short-Term or Long-Term Lease
The soft market creates a genuine strategic tension. Landlords under vacancy pressure prefer longer terms — they lock in occupancy, improve loan covenant compliance, and reduce re-leasing costs. That preference is leverage, and it cuts two ways.
A longer term — five to seven years or more — unlocks the largest concession packages: the highest TI allowances, the most free rent, the most aggressive parking terms. If your business is stable, your space needs are predictable, and you think market rents will hold or rise from here, locking in today’s effective rent with maximum concessions makes financial sense.
A shorter term — two to three years — preserves flexibility in a market that may keep softening, at the cost of a thinner concession package.
A middle path worth negotiating: a five-year lease with a tenant termination option at year three, exercisable with adequate notice and a defined fee. You get the upfront concessions of a longer deal and a bounded exit if circumstances change. Not every landlord will agree. In the current market, it’s worth asking anyway.
One more thing on renewals: push for a fixed rent formula rather than a market-rate renewal. “Fair market rent at the time of renewal” is not a neutral clause — it eliminates most of your protection if the market tightens before your renewal date. A renewal option capped against CPI or set at a defined percentage increase over your existing rate has actual value. A market-rate renewal option is largely decorative.
What You Are Probably Leaving on the Table
Many tenants lead with base rent negotiation and never get to the items where the real dollar value lives. Base rent is the number you see every month, so the instinct makes sense. But it’s often not where the biggest money is. Work through this sequence before your first substantive counter.
Free rent period. Anchor high — you can give ground, but you can’t recover months you didn’t ask for. On a five-year deal in a high-vacancy submarket, 6–12 months is realistic.
TI allowance. Price your actual buildout before the LOI is drafted. The gap between the allowance and your real construction costs comes out of your business, not the landlord’s pocket.
Operating expense cap. On any lease with a pass-through structure, negotiate a cap on controllable expense increases — 3 to 5 percent annually. Uncapped pass-throughs in an older building with deferred maintenance or Energize Denver obligations are an open-ended liability.
Parking. Ask for free parking or a meaningful discount, especially in DTC. In a submarket where landlords are already handing it out, there’s no reason to pay for it.
Renewal option with a rate formula. Not just the right to renew — the right to renew at a defined rate or cap. If your broker doesn’t raise this, you should.
Early termination right. Define the fee, the notice period, the conditions. Bounded flexibility is worth paying for, particularly for any business with uncertainty in its growth trajectory.
Sublease and assignment right. You may not plan to sublease, but businesses change. The right to sublease to an affiliate or successor without landlord approval — and to assign in connection with a sale of the business — should be in the lease from the start.
Personal guarantee scope. In Colorado, landlords routinely ask for personal guarantees from business owners on smaller leases, particularly for businesses without extensive operating history. This is negotiable. Push to limit the guarantee in duration, dollar amount, or both. Accepting a full-term, unlimited personal guarantee without pushing back is not a minor concession — your attorney should review this clause regardless of deal size.
On broker selection: use a tenant-rep broker. The structure of commercial real estate brokerage in Colorado means the landlord pays both sides of the commission, which creates a documented conflict of interest when a broker works primarily on the landlord side. Firms that operate as dedicated tenant representatives — Cresa Denver, Savills, and Tributary Real Estate all operate in this space locally — structure their practices around tenant clients. Ask any broker you’re considering: what percentage of your transaction volume is tenant-rep versus landlord-rep? The answer is informative.
Eight Questions to Answer Before You Sign a Letter of Intent
-
What is the effective rent, fully loaded? Subtract the amortized value of free rent and TI over the lease term, and account for parking cost. That’s the real number. Everything else is marketing.
-
What is included in the base year for operating expenses? The base year sets the floor above which you pay pass-through increases. A base year during a period of artificially low operating expenses can expose you to immediate reconciliation charges.
-
Does the TI allowance actually cover my buildout? Get a preliminary construction budget from a local contractor or space planner before finalizing the LOI.
-
Is there a sublease or assignment right if my business changes? Read the assignment and subletting clause before execution.
-
What is the landlord’s financial position on this building? A building near a loan maturity wall or in covenant distress is a different counterparty than a stable institutional owner. Your broker should be able to assess this.
-
Are capital projects planned for the building, and how are costs allocated? HVAC replacement, elevator modernization, lobby renovation, Energize Denver compliance — which flows to tenants through operating expense reconciliations, and which stays with the landlord? Get this in writing.
-
What are the renewal option terms? A renewal at a defined cap or formula protects you. A renewal at “fair market rent” mostly protects the landlord.
-
What is the personal guarantee ask, and what can I negotiate it down to? The first draft is not the final answer. Limit it in duration, amount, or both.
Denver’s vacancy rate won’t stay at 25 percent indefinitely. The conditions that exist right now — in DTC, in LoDo, in RiNo — reflect a specific collision of factors: pandemic-era space offloading, tech and energy sector rightsizing, remote work normalization, and the 16th Street Mall disruption. Some of those factors are reversing. Some will persist longer than brokers on either side would like to predict.
What’s clear is that for a business owner making a leasing decision in the next six months, the market is meaningfully favorable to tenants in ways it hasn’t been in years. The concessions are real. The leverage is real. Whether you capture it depends almost entirely on how prepared you are before you sit down at the table.
