Who Pays Commercial Real Estate Broker Fees?

Commercial sale transactions: how the fee is structured

On commercial sales, the seller typically pays the total broker fee. Rates often range from 4% to 6% on smaller deals (under $5M) and step down to 1–2% on larger institutional transactions where the absolute fee is still substantial — a 1.5% commission on a $40M industrial portfolio is $600,000, which funds a serious capital-markets engagement. Cooperating arrangements with a buyer’s broker are negotiated case by case and disclosed in the engagement letter.

On larger institutional transactions — say, $20M+ — it’s common to see a tiered structure: a base percentage on the agreed price plus a success fee on amounts above a target threshold. The structure is designed to align the broker’s incentives with maximising sale proceeds, not just closing the deal at any price.

Commercial lease transactions: landlord-paid and tenant-paid splits

On commercial leases, the landlord typically pays the total broker fee, calculated as a percentage of total lease value over the term — often 4–5% of net rent for the first year, declining for subsequent years (e.g. 4% Year 1, 3% Year 2, 2% Years 3–5). On a $50/sq ft net lease for 10,000 sq ft over 5 years, the broker fee structure could amount to $80,000–$120,000 split between listing and cooperating brokers.

On large or unusual deals — corporate headquarters relocations, multi-city expansion mandates, build-to-suit — the tenant may also pay their broker directly under a separate tenant-representation agreement. This is more common in the corporate occupier world than in small-business leasing, and is usually structured as a flat retainer plus a transaction success fee.

Why commercial fee structures vary so much

• Deal complexity: a multi-tenant industrial sale takes far more work — estoppel certificates, environmental reports, tenant interviews, lease-by-lease underwriting — than a small retail lease.
• Buyer/tenant sophistication: institutional clients often retain brokers on hourly or flat-fee terms, with negotiated success fees layered on top.
• Market conditions: tight markets see lower buyer-broker incentives because deals close themselves; soft markets see higher cooperating fees as landlords compete for tenants.
• Property type: office, retail, industrial, multi-family, hospitality, and special-use each have their own conventions and broker specialties.
• Geography: downtown core, suburban office park, and tertiary market deals follow different fee conventions in the same metro.

Always insist on the engagement letter before showings

Whether you’re a landlord, seller, tenant, or buyer, get the broker’s fee engagement in writing before the search begins. Verbal arrangements in commercial deals routinely go sideways at closing — disputes about who is the procuring cause of the introduction, whether a cooperating broker is owed a fee, what happens if a deal renews or extends, and whether HST is on top or included can all cost five and six figures if not nailed down up front.

The engagement letter should cover: total fee and split, payment trigger (typically lease commencement or transaction closing), exclusivity (and the duration of any tail period after expiry), HST treatment, what happens on renewal or extension, what happens if the deal restructures, and how disputes are resolved. See our commercial real estate buying guide for the full process and the engagement points to negotiate.

Who pays for what in a typical commercial deal

• Listing/landlord-side broker: paid by the seller/landlord per the listing agreement.
• Cooperating buyer/tenant broker: paid out of the listing-side fee in most arrangements; sometimes top-up from the buyer/tenant if the listed cooperating fee is below threshold.
• Tenant-rep broker on a corporate engagement: may be paid by the tenant directly under a tenant-representation agreement, in which case the tenant rep returns or rebates the cooperating fee from the landlord side.
• Property condition assessments, environmental, legal, accounting: typically each side pays its own.
• HST: 13% in Ontario, paid on top of broker fees, deductible by the paying party as a business expense.

Frequently Asked Questions

Do commercial brokers charge HST?

Yes, where applicable. HST applies on commercial brokerage fees in Ontario at 13% and is paid on top of the engagement fee. It’s recoverable as input tax credits by GST/HST registrants.

Can a commercial broker represent both sides of a deal?

Yes, with disclosed dual agency, but the engagement letters and disclosures are more detailed than residential. Most institutional buyers and sellers prefer separate representation to avoid any conflict-of-interest perception.

Are tenant-paid commercial fees deductible?

Generally yes as a business expense, but consult your accountant. Treatment varies by lease type, capitalisation rules, and whether the fee is for an initial lease, an extension, or a relocation.

What is a “tail period” in a broker engagement?

A tail period is the time after an exclusive engagement expires during which the broker is still owed a fee if the client closes a deal with a counterparty introduced during the engagement. Standard commercial tails run 60–180 days; corporate engagements sometimes longer.
