Commercial tenant representation in the Inland Empire means one broker works only for you — the tenant — through the search, the tour, the letter of intent, and the lease. Apex is a CCIM-led tenant rep brokerage covering industrial, retail, office, and land requirements from Ontario and Fontana to Hemet and the Coachella Valley.
Customarily the landlord pays your tenant rep broker out of the lease, by agreement. Structure varies deal to deal, so it is set in your engagement agreement and confirmed in writing before any letter of intent. Under California Civil Code §2079.16, a broker who represents the tenant only is still not the landlord’s agent, even when the landlord pays.
That statutory line beats any slogan. Under §2079.16 a buyer’s agent — and California treats a commercial tenant as the buyer — “is not the Seller’s agent, even if… the agent may receive compensation… in full or in part from the Seller.” You are owed a fiduciary duty of utmost care, integrity, honesty, and loyalty.
Tenant representation is advisory bought by the occupier. A commercial tenant broker defines the requirement, surveys the whole market rather than one building, runs the tour, negotiates the LOI, and works the lease to signature. The listing agent does that in reverse — a seller’s agent “acts as the agent for the Seller only.”
| Question | Tenant Rep Broker | The Building’s Listing Agent |
|---|---|---|
| Whose agent, legally | Yours — fiduciary duty of utmost care, integrity, honesty, and loyalty (§2079.16) | The landlord’s — “acts as the agent for the Seller only” (§2079.16) |
| Inventory shown | Whole market, plus sublease and off-market options | The buildings that agent is listing |
| Your bargaining position | Protected and used on your behalf | Known to the party paying them |
| Who typically pays | Customarily the landlord, out of the lease — structure varies, set in writing | The landlord, under the listing agreement |
| Benchmarking | Comparable deals, concessions, and days on market across submarkets | The asking rate on that building |
Civil Code §2079.13 defines “sale” to include “transactions for the creation of a leasehold exceeding one year’s duration,” with “Buyer” including a lessee and “Seller” a lessor (AB 2992). So California’s agency-disclosure regime governs your lease. Under §2079.14 your broker must deliver that disclosure “as soon as practicable before execution of a buyer-broker representation agreement.” Paperwork precedes touring.
Civil Code §2079.21 (AB 1289) bars a dual agent from disclosing either party’s confidential information without express permission — “facts relating to the client’s financial position, motivations, bargaining position, or other personal information that may impact price.” That is exactly what a tenant needs advocated, and the Legislature wrote the argument, not a broker.
Every Apex commercial real estate tenant rep assignment runs the same six stages, from a small Hemet retail suite to a Fontana big-box distribution requirement.
Base rent is what tenants fixate on and landlords defend hardest. The rest of the deal is where a tenant rep earns the assignment: free rent, tenant improvement allowance and delivery condition, escalations, renewal and expansion options, caps on controllable operating expenses, sublease rights, early termination, retail exclusivity.
Concessions are real and dated. Per CoStar’s Inland Empire Industrial Market Report, Q3 2026 (dated September 30, 2026): “Leverage remains with occupiers,” and “one to several months of free rent is common for new, larger-sized leases of 5 years or longer.” With elevated concessions, brokers have noted effective rental rates up to 40% lower, depending on location, size, and vintage.
Two named IE deals show the range. Hanchett Paper Company leased 223,000 SF in Fontana in May 2025 on a six-year, four-month term at $1.08/SF net monthly with six months free. Nor is free rent only for jumbo deals: in August 2025 WECRO leased 60,000 SF in Jurupa Valley on a two-year, four-month term with four months free. Days on market is leverage too — iDC Logistics took an 844,000 SF San Bernardino building after 30 months at $0.95/SF.
Apex quotes no benchmark TI allowance, escalation, or CAM cap, because no approved source publishes reliable IE or Coachella Valley figures. Each is negotiated per deal against your alternatives and the expense structure in your lease type. For the year-end audit itself, see our guide to CAM reconciliation.
The IE industrial market totals 795,864,262 SF, with vacancy at 8.7% and availability at 12.5% — a 15-year high — against a $1.03/SF market asking rent, per CoStar, Q3 2026. The triple-net asking-rent average for available space floored in 2025 Q1 and remains about 25% below its 2023 peak. The demand base: 1,721,700 nonfarm jobs and 5.3% unemployment in the Riverside–San Bernardino–Ontario MSA (BLS, June 2026, preliminary).
Leverage is not uniform, and honest advice says so. Per CoStar, availability peaks at 18% at 250,000–500,000 SF, runs around 14% at 100,000–250,000 SF, and sits in the 12% range from 500,000 SF up, including buildings over 1 million SF. It trends at 10% at 50,000–100,000 SF and under 7% for buildings smaller than 50,000 SF — so a small-bay tenant faces a tighter market than the headlines suggest. See the submarket-by-submarket breakdown in our guide to Inland Empire warehouse availability.
Geography is the other lever, and a tenant rep’s first job is testing whether your requirement can flex submarkets. A single-market broker cannot price that trade. Apex works the IE and Coachella Valley as one footprint.
| Submarket | Asking Rent / SF / Mo | Vacancy |
|---|---|---|
| Coachella Valley | $1.45 — highest of 15 | 4.3% |
| Upland/Montclair | $1.39 | — |
| Corona/Eastvale | $1.24 | 7.5% |
| Riverside | $1.07 | 7.5% |
| Airport Area | $1.06 | 8.2% |
| Beaumont/Hemet | $0.93 | 19.7% — highest shown here |
| San Bernardino | $0.90 | 10.5% |
| Redlands/Loma Linda | $0.90 | — |
| Moreno Valley/Perris | $0.86 — lowest of 15 | 9.6% |
| Chino/Chino Hills | — | 6.2% |
Rent and vacancy move in opposite directions there, which is the point. See Apex’s warehouse space cost breakdown; yard users start with industrial outdoor storage.
Sublease space is an elevated 19% of total IE industrial availability and trades more than 20% below direct space, per CoStar, Q3 2026. Roughly 40 buildings offer 50,000–200,000 SF of sublet space, and another 30 offer over 200,000 SF, typically $1.00–$1.50/SF.
That discount carries structure a tenant must underwrite: the sublease inherits the remaining master-lease term, the master landlord’s consent and recapture rights sit above the deal, and the sublandlord’s default becomes your problem. Pricing those risks is ordinary tenant rep work.
IE retail runs 6.0% vacancy and 6.6% availability against a $2.29/SF asking rent, up 3.1% year over year, per CoStar, Q3 2026. Tightness flips leverage back to landlords in the best trade areas: the Airport Area and South Riverside sit below 5% availability. Coachella Valley retail asks $2.25/SF at 8.2% vacancy and Beaumont/Hemet $1.88/SF at 6.5%, against Chino/Chino Hills at $3.03 and Twentynine Palms at $1.51. Exclusivity, co-tenancy, signage, and use clauses often outweigh rent.
Apex represents office tenants across both markets on the same process. IE office is the tightest of the three asset classes: 4.7% vacancy and 5.9% availability against a $2.57/SF monthly asking rent — quoted full-service, about $31.00/SF a year — up 3.0% year over year, per CoStar, Q3 2026. Ask, and we will pull comparables.
Industrial is the deepest IE tenant rep market, and the data above is industrial. Small-bay flex through big-box distribution, plus truck yards and outdoor storage, run the same six stages.
Even with rents off their peak, a tenant rolling off an older lease is stepping up. Per CoStar, Q3 2026, IE industrial market asking rents are still up approximately 20% from five years ago and have nearly doubled over the decade. IE retail has moved the same direction: market rents are up nearly 40% over the decade, and average asking rents stand at $27.00/SF a year, triple-net.
A renewal letter arrives with a number and a deadline, and a tenant with no alternative has no leverage. Engaging a rep early enough to run a real survey and table a competing LOI turns a renewal into a negotiation. For the negotiation playbook, see our guide to commercial lease renewal.
Two quotes at the same figure can be very different deals depending on who pays taxes, insurance, and maintenance. Read a proposal before the tour:
Not every requirement justifies a formal engagement, and pretending otherwise is how these pages lose credibility. Keep scope light when:
Even then a short conversation costs nothing. A tenant rep should never be a formality added after you picked the building and named your budget.
Assignments are led by Robert Mendieta Jr., CCIM, Associate Broker, California DRE #01422904, with 20+ years in commercial real estate and $500M+ in career transaction volume. CCIM is not a course certificate: more than 20,000 professionals have completed the program since 1967, and candidates must submit a Portfolio of Qualifying Experience — the Traditional track requires at least two but fewer than five years of full-time commercial work — plus coursework and an exam, per CCIM Institute. Joseph Lombera, Commercial Agent and CMO (DRE #01971957), supports research.
Sophisticated tenants already work this way. In CoStar’s table of the 40 largest IE industrial leases of the trailing 12 months through Q3 2026, 27 name a tenant rep company. The data behind every recommendation lives in the quarterly Apex market reports.
Customarily the landlord, out of the lease, by agreement. Structure varies by deal and is fixed in writing in your engagement agreement before any letter of intent. California Civil Code Section 2079.16 states a buyer’s agent is not the seller’s agent even if compensated, in full or in part, by the seller.
A tenant rep broker defines your requirement, surveys the whole market including sublease and off-market space, runs the tour, negotiates the letter of intent and lease business terms, and manages delivery through occupancy.
That agent works for the landlord. California Civil Code Section 2079.16 states a seller’s agent under a listing agreement acts as the agent for the seller only. Section 2079.21 also bars a dual agent from disclosing a party’s financial position, motivations, or bargaining position without express permission.
CoStar’s Inland Empire Industrial Market Report for Q3 2026 states leverage remains with occupiers, with one to several months of free rent common on new, larger leases of five years or longer. Vacancy measures 8.7% and availability 12.5%, a 15-year high. But availability reaches 18% at 250,000 to 500,000 SF and is under 7% for buildings smaller than 50,000 SF.
Effective rent is what you actually pay once concessions are spread across the term. Per CoStar, Q3 2026, the average asking rent for available Inland Empire industrial space sits about 25% below its 2023 peak, and in combination with elevated concessions, brokers have noted effective rental rates up to 40% lower, depending on location, size, and vintage. CoStar does not say what the 40% is measured against, so treat it as an upper bound, not the typical deal. From that report: Hanchett Paper Company leased 223,000 SF in Fontana in May 2025 on a six-year, four-month term at $1.08 per SF net monthly with six months free.
Early enough to run a full market survey and table a competing letter of intent, because a tenant with no alternative has no leverage. Per CoStar, Q3 2026, Inland Empire industrial market asking rents are still up approximately 20% from five years ago and have nearly doubled over the past decade.
Apex represents industrial, retail, office, and land tenants across the Inland Empire and Coachella Valley. Inland Empire retail runs 6.0% vacancy and a $2.29 per SF asking rent per CoStar, Q3 2026, with Coachella Valley retail at $2.25 per SF. Inland Empire office runs 4.7% vacancy and a $2.57 per SF monthly asking rent, quoted full-service (about $31.00 per SF a year), in the same CoStar Q3 2026 data.
