A lease rate can look straightforward until commission enters the conversation. So, how do commercial realtors get paid on leases? In most transactions, the landlord pays a commission to the brokerage, which is then shared between the listing representative and the tenant's representative when both are involved. The exact amount, timing, and calculation method depend on the property type, lease term, market conditions, and the agreements signed before the deal is finalized.
For an Ottawa landlord or business tenant, commission is not a minor line item. It can affect the economics of the lease, the incentives around term length and renewals, and the value of having experienced representation at the table. Clear expectations early help both sides negotiate with fewer surprises.
How Commercial Realtors Get Paid on Leases
Commercial leasing commissions are commonly calculated as a percentage of the total base rent payable over the initial lease term. Base rent is the rent charged for the space itself. It generally does not include operating expenses, property taxes, utilities, insurance contributions, or other additional rent charges that may apply under a net lease.
For example, a 2,000-square-foot office lease at $24 per square foot in annual base rent produces $48,000 in base rent per year. Over a five-year initial term, the total base rent would be $240,000 before any annual escalations. If the agreed leasing commission were 5 percent of the total base rent, the total commission would be $12,000.
That commission may be paid to one brokerage or divided between two. If the landlord has a listing broker and the tenant has its own broker, the landlord's brokerage typically shares the commission according to the co-brokerage arrangement. The split between individual agents and their brokerages is handled internally and does not usually change the tenant's lease obligation.
Rates are negotiable. A short-term lease, a difficult-to-lease industrial unit, a high-credit tenant, a large retail footprint, or a major office relocation can each produce a different commission structure. There is no single percentage that applies to every commercial lease.
Who Pays the Commercial Lease Commission?
In a conventional commercial lease, the landlord pays the commission. The cost is a business expense tied to securing a tenant and is often considered alongside tenant improvements, free rent, legal costs, marketing, and vacancy carrying costs.
That does not mean a tenant is unaffected by commission. Landlords build all leasing costs into their broader financial decisions. A landlord evaluating two offers may compare not only proposed rent, but also lease length, build-out requirements, inducements, tenant covenant strength, renewal rights, and brokerage fees. A tenant who understands those economics is better positioned to make a clean, credible proposal.
There are exceptions. A tenant may agree to compensate a broker directly under a tenant representation agreement, particularly for specialized assignments, portfolio searches, confidential requirements, or situations where no landlord-paid commission is available. A tenant could also retain an advisor on a fee basis for lease analysis, site selection, market strategy, or negotiation support beyond a standard brokerage arrangement.
The key protection is simple: ask how the representative will be compensated before substantial work begins. The answer should be clear, documented, and consistent with the representation agreement and lease negotiations.
What Determines the Commission Amount?
The commission formula is only one part of the calculation. Several variables can materially change what a commercial realtor earns on a lease.
Lease term and renewal options
Longer initial terms often produce higher total commissions because there is more base rent over which to calculate the fee. A landlord may pay a different rate for the first five years than for years six through 10, or pay no commission on optional renewal periods unless the tenant exercises the option.
Renewal commissions deserve particular attention. Some agreements provide a reduced commission if an existing tenant renews. Others provide a commission only if the broker actively negotiates the renewal or brings the parties back together after a difficult process. If a renewal is likely to be important to your business plan, confirm the commission treatment before it becomes a point of dispute.
New leases, expansions, and relocations
A new lease with a new tenant generally commands more work than a straightforward renewal. The representative may market the property, qualify prospects, arrange tours, prepare proposals, coordinate financial information, negotiate business terms, and help move the transaction toward a signed lease.
An expansion within the same building may be handled differently. So may a relocation by an existing tenant to another property owned by the same landlord. The commission agreement should define what triggers payment, especially where multiple spaces, affiliated companies, or staged occupancy are involved.
Property type and market conditions
Retail, office, industrial, medical, flex, and mixed-use properties have different leasing dynamics. A retail lease may require more time spent on use restrictions, signage, exclusivity clauses, parking, patio rights, and co-tenancy concerns. Industrial tenants may focus more heavily on loading, clear height, power, zoning, and access. Office tenants may place more weight on layout, transit, parking, and improvement allowances.
Commission reflects the full assignment, not simply the act of opening a door. In a market with elevated vacancy, securing a qualified tenant can require more marketing, persistence, and negotiation. In a highly competitive location, the challenge may be structuring terms that protect the landlord while keeping the strongest tenant engaged.
Lease incentives and landlord work
Free rent and tenant improvement allowances do not automatically reduce the commission base, but the language matters. Some commission agreements calculate the fee on gross scheduled base rent before free-rent periods. Others use net effective rent or exclude certain inducements. If the lease includes significant construction, phased possession, or rent abatement, the commission agreement should state precisely how the calculation works.
When Is the Commission Paid?
Commercial leasing commissions are often paid when the lease is fully executed, although payment may be delayed until the tenant takes possession, satisfies conditions, or pays its first rent. For larger or longer-term transactions, a landlord may pay part of the commission at lease signing and the balance at occupancy or after the first year of the term.
This timing matters because a signed lease is not always the end of the risk. A tenant may fail to obtain permits, financing, board approval, or required licensing. The lease may contain conditions that allow one party to terminate before possession. A well-drafted commission agreement addresses whether the commission is earned at signing, paid at possession, or subject to repayment if the tenant defaults early.
Landlords should also understand the distinction between an agreement to lease and a final lease. An agreement to lease can establish core business terms, but it may still leave detailed legal language to be completed. Whether commission is payable at that earlier stage depends on the brokerage agreement and the specific documents involved.
Why Tenants Should Still Have Representation
Because the landlord commonly pays the commission, some tenants assume they can save money by negotiating alone. Sometimes that approach works for a small, simple renewal. Often, it leaves the tenant without a market comparison or a professional focused on lease protections that can outlast the initial rent term.
A tenant representative can assess available alternatives and help negotiate beyond the asking rate. The meaningful issues may include renewal options, annual increases, assignment and subleasing rights, restoration obligations, exclusivity, expansion rights, operating-cost audits, signage, repair responsibilities, and personal guarantees.
A landlord's representative has a different duty: to protect the landlord's leasing objectives, building economics, and risk profile. That is appropriate and expected. It is also why tenants should be precise about who represents whom before sharing sensitive information about revenue, financing, growth plans, or negotiating limits.
Questions to Ask Before You Sign
Before accepting a proposal, landlords and tenants should confirm the practical details that influence commission and representation. Ask whether there is a written brokerage or representation agreement, who is responsible for payment, how the commission is calculated, when it becomes payable, and whether renewal, expansion, assignment, or early termination changes the amount.
For landlords, it is equally useful to confirm whether commission is owed if a prospect introduced by a broker later leases through another entity or affiliated business. For tenants, ask whether the representative receives compensation from the landlord and whether any separate fee could apply. Clear answers prevent a commission issue from surfacing after substantial negotiation has already taken place.
Commercial leasing is a financial and operational commitment, not just a monthly rent decision. Before you commit to space or place a property on the market, make the compensation structure part of the strategy discussion. The right advisor should be able to explain the numbers plainly, identify the trade-offs, and keep the agreement aligned with the goals that matter after the keys change hands.
