What does a commercial real estate broker do? This guide answers from the primary sources: California’s statutes as the Department of Real Estate publishes them in the 2026 Real Estate Law, plus federal labor data.
The direct answerWhat Does a Commercial Real Estate Broker Do?
A commercial real estate broker represents a client (a tenant, landlord, buyer, seller or investor) in leasing, buying, selling or financing nonresidential property. The broker prices the property, finds space, buyers or tenants, negotiates the terms and manages the deal to a signed lease or closing, for compensation set by agreement, typically in writing.
California law defines a real estate broker by acts done “for another or others” for compensation: selling or buying real property, leasing it, and negotiating loans secured by it. So what do commercial real estate brokers do? Those acts, for owners and occupiers of industrial, office, retail and land.
Key Takeaways
- The law defines the job. Sales, leasing and real-estate-loan acts for others, for compensation, require a California license.
- Broker, agent and REALTOR® differ. An “agent” is usually a salesperson working under a responsible broker; REALTOR® is a membership mark.
- Your broker owes you a fiduciary duty. Dual agency needs both sides’ knowledge and consent.
- Pay is set by agreement. Compensation on sales and leases over one year must be in writing, and who pays does not by itself decide whom the broker represents.
What Is a Commercial Real Estate Broker Under California Law?
A commercial real estate broker is a real estate broker, licensed by the California Department of Real Estate (DRE), who focuses on commercial property. The law regulates the activity; “commercial” describes the property and clients.
Acting as a broker or salesperson without a DRE license is unlawful (B&P Code § 10130). Section 10131 defines the broker by acts done for others for compensation:
- Sales: selling or buying, obtaining listings, and negotiating the purchase, sale or exchange of real property or a business opportunity.
- Leasing: leasing or renting, soliciting prospective tenants, negotiating leases and collecting rents.
- Loans: soliciting borrowers or lenders, or negotiating loans secured by real property.
Leasing stands on its own in that definition, so negotiating a lease is as much licensed broker work as negotiating a sale. The Civil Code separately defines “commercial real property” as all real property in the state except single-family residential property, certain dwelling units, mobilehomes, vacant land and recreational vehicles (Civ. Code § 2079.13(c)). Selling your own building without a broker? See commercial property for sale by owner.
Who’s whoCommercial Real Estate Broker vs Agent vs REALTOR®: What’s the Difference?
A broker can run their own business; an “agent” is usually a licensed salesperson working under a responsible broker; REALTOR® is a membership mark, not a license. The commercial real estate broker vs agent distinction:
| Role | What it means | Supervision and pay | Source |
|---|---|---|---|
| Broker | Licensed to do sales, leasing and loan acts for others and to manage their own business | As responsible broker, supervises salespersons | B&P §§ 10131, 10015.1; BLS |
| Salesperson (“agent”) | Licensed salesperson retained by a broker to do the same acts | Works under a responsible broker; paid only through that broker | B&P §§ 10016, 10137 |
| REALTOR® | A National Association of REALTORS® member who subscribes to its Code of Ethics | A membership, not a license level | NAR |
In the Civil Code’s agency rules, the “agent” in a transaction includes the broker under whose license the listing or offer is taken, and that broker bears responsibility for its salespersons and broker associates. The broker license also takes more to earn: a written exam, eight college-level courses, and either two years of full-time licensed salesperson experience within the last five years, two years of equivalent experience, or a four-year degree with a real estate major or minor. The salesperson exam requires three courses.
On broker vs realtor: the National Association of REALTORS® defines REALTOR® as a federally registered collective membership mark. It describes association membership, not which license a person holds.
The work itselfWhat Does a Commercial Real Estate Agent Do in Leasing, Sales and Investment?
A commercial agent prices, markets and negotiates leases and sales for one side of the table: the tenant or landlord, the buyer or seller. A tenant’s broker and a landlord’s broker work the same lease from opposite sides.
The Bureau of Labor Statistics lists core duties such as advising clients on prices and market conditions, comparing properties to determine a competitive price, presenting offers, mediating negotiations and preparing purchase agreements and leases. In commercial work, those duties sort into five assignments.
| Assignment | What the broker does | Related guide |
|---|---|---|
| Leasing for a tenant | Defines needs, runs the search and tours, drafts the letter of intent (LOI), negotiates the lease | How to lease commercial property; letter of intent |
| Leasing for a landlord | Prices space from comparable leases, markets it, vets tenants, negotiates terms | Landlord representation |
| Selling | Prices and markets the property, presents offers, keeps the contract on track to closing | Property valuation |
| Buying | Finds and compares properties, structures the offer, coordinates due diligence | Due diligence checklist |
| Investing | Underwrites net operating income and cap rate before price; sources exchange replacement property | Cap rate; 1031 exchange advisory |
Apex takes tenant, landlord, buyer and seller representation assignments, plus 1031 exchange and sale-leaseback advisory. For a tenant, that means one broker working only for the tenant through the search, the tour, the letter of intent and the lease; see tenant representation and our recent transactions.

Same region, same quarter, very different leverage by property type. A broker who works your property type reads those conditions into every price and counteroffer. For warehouse and yard deals, see what an industrial real estate broker does.
Two different businessesHow Is a Commercial Real Estate Agent Different From a Residential Agent?
The licenses are the same; the property, the clients and the math are different. Most real estate brokers and sales agents sell residential property, according to the BLS; others sell commercial, and a small number sell industrial, agricultural or other real estate.
California’s agency-disclosure rules reach sales of commercial real property and leases longer than one year, treating the landlord as the “seller” and the tenant as the “buyer.” In practice, commercial work differs in two ways:
- Leases carry the deal. Term, rent structure, expense pass-throughs and options are negotiated clause by clause; see types of commercial leases.
- Value follows income. Investors price buildings on net operating income, cap rate and lease terms, not nearby home sales.
What Duties Does a Commercial Broker Owe You in California?
Your own broker owes you a fiduciary duty, and every broker in the deal owes both sides honesty, good faith and disclosure of known material facts.
Under the statutory disclosure form in Civil Code § 2079.16, a seller’s agent owes the seller “a fiduciary duty of utmost care, integrity, honesty, and loyalty.” A buyer’s agent can, with consent, act for the buyer only, even if the seller pays some or all of the compensation. On a lease longer than one year, read “landlord” for seller and “tenant” for buyer.
One broker can represent both sides only with the knowledge and consent of both. A dual agent may not, without permission, tell one side what the other shared in confidence about price, such as a seller’s willingness to accept less than the listing price. The seller’s agent gives the agency disclosure form before the listing agreement; the buyer’s agent gives it as soon as practicable before a buyer-broker representation agreement and offer are signed.
Not legal or tax advice. The same form says a real estate agent is qualified to advise about real estate, and legal or tax advice should come from a competent professional. Apex is not a law, tax or accounting firm. For legal or tax questions about a specific deal, talk with your attorney or CPA.
How Do Commercial Real Estate Brokers Get Paid?
Through compensation set in a written broker agreement, which also says who pays it. Under Civil Code § 1624, an agreement employing a broker to buy or sell real estate, or to lease it for longer than one year, for a commission is invalid unless it, or a note or memorandum of it, is in writing and signed by the party to be charged or that party’s agent.
Who pays does not by itself settle whom the broker represents, and a listing agent and a selling agent may agree to share a commission. California’s “not fixed by law” commission notice is required on printed or form compensation agreements for sales of residential property of one to four units; on commercial deals, the amount, timing and payer are negotiated terms of the written agreement. For who pays a tenant’s broker on Apex assignments, see tenant representation.
Hiring wellHow Do You Choose a Commercial Real Estate Broker?
Match the broker to your property type, market and side of the deal, then check their pricing, conflicts policy and agreement.
- Property type and submarket. Industrial, retail and office can sit in very different conditions in the same quarter.
- Whom they represent. Ask whether they will act for you only or as a dual agent.
- How they price. Ask for the comparable leases or sales, the income underwriting and the quarter the data covers.
- What designations signal. The CCIM Institute says its designation represents expertise in financial, market, user and investment analysis, and negotiations; see what a CCIM is.
- A clear written agreement. Scope, term, compensation and who pays, on paper, after you receive the agency disclosure form.
Commercial Real Estate Broker: Frequently Asked Questions
What is the difference between a commercial real estate broker and an agent?
A broker holds a broker license and can run their own business. An agent is usually a licensed salesperson retained and supervised by a responsible broker and paid only through that broker. A California broker license takes more experience and coursework.
Is a REALTOR® the same as a commercial real estate broker?
No. REALTOR® is a membership mark of the National Association of REALTORS® for members who subscribe to its Code of Ethics. Broker and salesperson are licenses issued by the California Department of Real Estate.
What does a commercial real estate agent do day to day?
Advises clients on prices and market conditions, compares properties, markets space or buildings, presents offers, mediates negotiations and prepares purchase agreements and leases. For a tenant, that runs from the search and tours through the letter of intent and the lease.
Who pays a commercial real estate broker?
Whoever the written agreement says pays. California requires broker compensation agreements on sales and on leases longer than one year to be in writing. A tenant’s broker can still act for the tenant only, even if the landlord pays some or all of the fee.
Can one broker represent both the landlord and the tenant?
Yes, but only with the knowledge and consent of both. That is dual agency. A dual agent may not tell one side, without permission, the price the other side would accept or pay.
How is a commercial broker different from a residential agent?
The licenses are the same; the work is not. Most real estate brokers and sales agents sell residential property, according to the BLS. Commercial brokers work with businesses and investors, where value follows net operating income and lease terms.
Does a commercial real estate broker give legal or tax advice?
No. California’s statutory agency disclosure form says a real estate agent is qualified to advise about real estate, and legal or tax advice should come from a competent professional. Apex is not a law, tax or accounting firm, so talk with your attorney or CPA.
