Office Vacancy Falls to 18.2%: How a Small Business Should Negotiate a Lease Now

US office vacancy stands at 18.2% in CBRE's Q3 2026 report, but prime space is much tighter at 11.9%. A small business should negotiate hardest in older, non-prime buildings, where the asking-taking rent spread of 9.9% leaves room, and plan earlier for prime space, where rents are rising and choices are shrinking.

New Club Cocoon covers commercial property and leasing for business owners who rent space, along with brokers and small landlords. This explainer is for tenants of 1,000 to 10,000 square feet who are renewing or relocating in the next year. It covers the market numbers, what they mean for your bargaining position and the terms worth asking for.

What does CBRE's Q3 2026 office data show?

CBRE's Q3 2026 U.S. Office Market Report shows overall vacancy at 18.2 percent, down 60 basis points from a year ago and 10 basis points from the prior quarter. That is the fifth straight quarterly decline. Prime vacancy is 11.9 percent, down 250 basis points year over year.

Leasing is strong. CBRE counts 63.8 million square feet leased in Q3, up 4 percent year over year and the highest quarterly total since Q4 2024. Net absorption was 4.9 million square feet, the tenth straight positive quarter. CBRE expects 2026 to pass the 2022 record for leasing.

Supply is the other half of the story. Completions fell 76 percent from a year earlier to 1.5 million square feet in Q3, and 2026 is on track for the lowest annual total since CBRE began tracking in 1990. Under construction is 20.1 million square feet, which is 84 percent below the Q2 2020 peak.

Put those together and you get a split market. The best buildings fill up and raise rents. Older buildings hold most of the empty space.

How much room do you have to negotiate rent?

The room to negotiate is the gap between asking and taking rent. CBRE reports a 9.9 percent asking-taking spread in Q3, narrower than before but above the 8.6 percent seen in 2019. On a $38 per square foot ask, a 9.9 percent spread is about $3.76 a square foot.

Here is what that means for a 4,000 square foot suite. At $38 a foot, the asking rent is $152,000 a year. A 9.9 percent gap equals about $15,000 a year, or $75,000 over a five-year term, between what the landlord advertises and what tenants net out after concessions.

The gap does not always arrive as a lower base rent. Landlords often prefer to keep the headline rent high and give free rent or a larger tenant improvement allowance. Those terms still lower your effective rent. Compare offers on a net effective basis, which spreads all concessions across the term.

In my view, a small tenant should ask for both: a modest base rent cut and a clear package of concessions. The ask is easier to defend when you point to comparable deals, not just to national averages.

Where do small tenants have the most leverage?

Small tenants have the most leverage in older, non-prime buildings and in markets with high vacancy. The 6.3-point gap between overall vacancy and prime vacancy shows where the empty space sits. A landlord with a half-empty building will trade rent for a signed lease.

The table below sorts typical situations by leverage.

Leverage also depends on timing. A landlord with a lease expiring soon in the same building is more flexible than one with a full rent roll. Ask the building's leasing agent which spaces have been vacant longest and which tenants are leaving.

If you work with a broker, ask how the fee is structured. Our guide on tenant rep broker fees and who pays explains why a tenant rep often costs the tenant little, and how to check that the incentives line up.

Which lease terms matter most in this market?

Beyond rent, five terms deserve attention: free rent, the tenant improvement allowance, escalations, renewal options and early termination. In a market where rents are rising, locking in the escalation and a renewal right matters as much as the starting number.

The tenant improvement allowance links to your build-out budget and your taxes. Our explainer on how to deduct fit-out costs in 2026 shows how those costs are treated at tax time, which can change how you value an allowance versus a rent cut.

Do not forget the legal costs of space. Compliance can shift to you under some leases. Read our piece on ADA compliance in a commercial lease and who actually pays before you sign.

How should you structure your search?

Start six to twelve months before your lease ends, and work in a clear order. First, read your current lease for notice deadlines and restoration duties. Second, define your needs: size, location, parking, signage and timing. Third, tour three to five buildings, including at least one older option.

Fourth, request proposals from each landlord on the same basis. Ask for base rent, free rent, allowance, escalations, operating expense estimates and term. Put the numbers in one table and calculate net effective rent for each.

Fifth, use competing offers. A landlord who knows you have another proposal will move faster. Be honest, and do not invent offers. A simple statement such as "we are comparing two other buildings" is enough.

The Small Business Administration reminds owners that location shapes the taxes, zoning rules and regulations that apply to a business. Its page on picking your business location also notes that property values, rental rates, utilities and local taxes vary by place, and that zoning must match your use. Check zoning before you sign.

Is the picture different in Canada?

The picture is similar but measured differently. Altus Group's Canadian office market update for Q3 2026 reports national office availability of 15.1 percent, down 110 basis points from a year earlier. Availability counts space that is on the market, not only empty space, so it is not directly comparable to CBRE's vacancy rate.

Markets differ widely. Altus lists Halifax at 7.7 percent availability, the lowest, and Calgary at 20.5 percent, the highest. Toronto sits at 15.1 percent and Montreal at 16.1 percent. A tenant in Calgary has far more bargaining power than one in Halifax.

Altus also notes that Class A asking rents in downtown Toronto rose to $60.72 a square foot, and that the construction pipeline is near a historic low. The same split between prime and older space shows up north of the border.

What mistakes should small tenants avoid?

The first mistake is negotiating only the base rent. A landlord can give up rent and make the money back through operating expenses, fees or a weaker allowance. Always compare the total cost over the term.

The second is waiting too long. A tenant with six months left on a lease has few options, and landlords know it. Starting early gives you time to walk away.

The third is skipping the details of the space. Ask about heating and cooling hours, after-hours charges, parking and signage. A low rent can hide high extras.

The fourth is signing without a plan for the end. Read the restoration clause, which says what you must remove or repair when you leave. A forgotten clause can cost thousands at move-out.

What if you are thinking about buying instead?

Buying can make sense if you plan to stay for many years and can finance it. Our look at when an SBA 504 loan beats renting walks through the numbers. In a market where rents are rising and prime space is tight, the lease-or-buy question deserves a fresh look.

Run both options over ten years. Include rent increases, expected maintenance, property taxes, interest and the cost of capital. Many small firms find that leasing keeps cash free for the business, while owning builds equity but ties up money.

The practical answer

Treat the 18.2 percent headline with caution. The market is split, and your leverage depends on the building, not the national number. New Club Cocoon's editors suggest focusing on non-prime space, comparing net effective rent and asking for concessions, not just a lower base rate.

Your next step is to list your lease notice date and your three must-have terms. Then tour one prime and two non-prime options, so you can see the real price of each.
