Where Inland Empire Renters Come From

The Inland Empire, the Riverside-San Bernardino-Ontario metro, has 495,428 renter households, and 34.2% of its households rent (U.S. Census ACS 2020–2024). That is well below the California figure of 44.1%, because this is a region built on single-family homes. Median gross rent is $1,846 a month, up 39.2% from $1,326 in the 2015–2019 survey, and median household income rose 37.7% to $89,662. Rents are still heavy for many: 59% of renters spend 30% or more of their income on housing.

Logistics is the base of the economy. UC Riverside researchers put transportation, warehousing and utilities at about 16.4% of regional jobs, and in 2021 the sector counted about 185,800 workers across 4,299 warehouses. Amazon employs about a third of the region's warehouse workers, by one labor researcher's estimate. In Moreno Valley alone, the city's 2025 financial report lists March Air Reserve Base with 7,000 workers, Riverside University Health System's medical center with 4,533 and an Amazon fulfillment center with 3,733. Ontario International Airport handled a record 7.1 million passengers and 835,129 tons of freight in 2025.

Health care is now adding jobs faster than freight. Northmarq reported that education and health services grew 7.1%, or 23,800 jobs, in the year to mid-2026, while total employment rose only 0.5%. Loma Linda University Health, Kaiser Permanente and the county hospital systems anchor that growth. For owners, this mix brings steady demand from working households. Wages in warehouse jobs often sit near the low end of the scale, though, so those households have limited room to absorb big rent increases.

New Supply And Rents In The Inland Empire

The region is coming out of its heaviest construction cycle in years. Northmarq counted 3,918 units delivered in 2025, about the same as 2024, and asking rents ended 2025 at $1,991, down 0.5%. By the second quarter of 2026, vacancy was 5.2%, absorption over 12 months reached 3,300 units, and average asking rent was $2,035, up 0.7% in a year. CoStar reported in August 2026 that rent growth was rising from a nearly 15-year low as demand caught up with completions.

The pipeline is shrinking. Northmarq expects about 3,100 completions in 2026, 21% fewer than 2025, with roughly 3,350 units under construction and permits on pace to fall about 50%. More than 1,400 of the units under construction sit in Greater Ontario and Rancho Cucamonga. Class B and C vacancy was 4.2% at mid-2026, below the 6.3% for Class A, which shows where the new buildings are competing.

The Census puts the metro's rental vacancy at 4.2%. That rate covers all rentals, including houses, so it isn't directly comparable to broker figures for large apartment communities, although here the two are close. Only 12.5% of homes, or 201,900, are in buildings with five or more units, and that count grew just 0.6% in five years. The median home was built in 1987, younger than in most coastal California metros. For buyers looking at apartment syndications in Inland Empire cities, Northmarq reported a 2026 median sale price near $217,900 a unit, down about 30% from 2025, which gives older Class B and C buildings room to be underwritten at today's rents.

Inland Empire Submarkets We Watch

The region covers two large counties, and rent and vacancy vary a lot between submarkets.

Where Inland Empire Stands Among Its Peers

Among the 276 California cities we track, Inland Empire ranks 194th for median gross rent, 196th for renter share and 52nd for five-year rent growth. Its rents fall in the middle of the pack. In raw numbers, Inland Empire has about 115,234 more residents, 4,499 fewer renter households and 1,204 more homes in buildings with 5 or more units than in the 2015–2019 survey. With fewer renter households than before, a building has to win tenants from competitors rather than from new demand.

Inland Empire Compared With California

Inland Empire's median gross rent of $1,846 is below the California median of $2,036, and its renter share is 34.2% compared with 44.1% statewide.

Rent Versus Income In Inland Empire

The median rent in Inland Empire works out to $22,152 a year, about 24.7% of the median household income of $89,662. Under the common 30% guideline, a household needs about $73,800 a year to cover that rent comfortably. That's close to the California figure of 24.6%. Renters usually earn less than the all-household median, so the real burden for tenants is higher than this simple ratio shows.

Since the 2015–2019 survey, the median rent rose $520 a month ($6,240 a year), while median household income rose $24,548 a year. The two have moved together, so affordability today looks much like it did five years ago.

What We Look For In An Inland Empire Apartment Building

Skyline buys 5+ unit apartment buildings in Inland Empire that either run well today or can run better with new management or renovation. We start with rents, occupancy and the condition of the building, and we price on what the property earns now.

Property taxes are a big line item for any California apartment building. We underwrite the tax bill after purchase, not the seller's current bill, since a sale often resets the assessment. California caps annual rent increases on most apartments older than 15 years under the Tenant Protection Act (AB 1482), and cities such as Los Angeles, San Francisco and Oakland have stricter local rent control. Our rent-control guides explain how these rules work. Insurance quotes in California reflect wildfire risk, so we get a quote before we make an offer.

Given how fast rents rose here, we assume much slower rent growth going forward and make sure the deal still works if rents stay flat for a while.

Due Diligence For Apartment Syndications In Inland Empire

The data on this page turns into a short checklist for evaluating an apartment syndication in Inland Empire.

• What vacancy does the plan assume? Rental vacancy in Inland Empire is 4.2%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 39.2% over five years. Ask whether the plan assumes that pace continues, and what happens to the deal if rents stay flat.
• How was the property tax bill estimated? A sale often triggers a reassessment, so the bill after purchase can be well above what the seller pays today.
• How big is the repair reserve? The median home in Inland Empire was built in 1987, and even newer buildings need money set aside for roofs, HVAC and appliances.
• How will the building hold occupancy? Renter households in Inland Empire fell 0.9%, so the plan should show how it keeps units full.
• How and when does capital come back? Ask what the plan is for a refinance or sale, and what happens if that takes longer than expected.

How Passive Investing In An Inland Empire Apartment Syndication Works

In an apartment syndication, Skyline acts as the general partner. We find the Inland Empire property, negotiate the purchase, arrange the loan and oversee management and any renovation. Limited partners put in capital and own a share of the entity that owns the building. They don't sign on the loan or deal with tenants and repairs.

Expect your money to be tied up for years, with no easy way to sell your share early, and remember that any investment can lose money. Most deals are open only to accredited investors under Rule 506(b) or 506(c). See investing with Skyline Capital for how we work with limited partners.
