Renting in East Contra Costa: Antioch, Pittsburg, Brentwood and Oakley in 2026

Most Bay Area rent searches end the same way. You set a budget, you draw a circle around your job, and nothing inside the circle works. East Contra Costa is where a lot of those searches go next, and it is the one part of the Bay Area that still has one bedrooms under $2,000 in real buildings, not just in listings that turn out to be scams.

This is the stretch along Highway 4 past Concord: Pittsburg, Antioch, Oakley and Brentwood, sitting where the Sacramento and San Joaquin rivers meet the Delta. About 300,000 people live out here. The rent is genuinely lower. The tradeoffs are genuinely real, and they are not the ones people expect.

What rent actually costs here in 2026

Here is where the four cities sit this year, based on current market data. Treat these as center-of-the-range numbers, since what you pay depends heavily on whether you are renting an apartment or a house.

Antioch

The largest of the four at roughly 115,000 people, and the cheapest apartment market. Average apartment rent runs around $2,100, which is down slightly from last year rather than up. One bedrooms average close to $1,890 for about 690 square feet, and two bedrooms land near $2,290 for about 940 square feet. Roughly 38 percent of Antioch rentals fall in the $1,500 to $2,000 band, which is the highest concentration of genuinely sub-$2,000 units anywhere in the nine counties.

Single family houses are a different market. The median asking rent on Antioch houses runs closer to $3,000, because you are renting three or four bedrooms and a yard.

Pittsburg

Smaller (around 76,000) and priced just above Antioch. One bedrooms cluster between roughly $1,850 and $2,000 depending on which source you check. Pittsburg has more mid-rise apartment inventory near the Highway 4 corridor and a genuinely pleasant older downtown near the waterfront, which is about a mile from the BART station and not walkable to it in any practical sense.

Brentwood

The expensive one, and the one people are surprised by. Average rent is around $2,725, up slightly over the past year. One bedrooms average near $2,340, two bedrooms near $2,720, and three bedrooms near $3,360 for about 1,430 square feet. Fifty six percent of Brentwood rentals fall between $2,500 and $3,000. You are paying for newer construction, better rated schools and a well kept downtown, and you are paying roughly $450 a month more than Antioch for a one bedroom.

Oakley

The smallest and the most house dominated. Apartment stock is thin, so the averages swing. Studios run near $1,395, one bedrooms near $1,600 and two bedrooms near $2,150. Three bedroom houses push past $3,300. If you want a yard for under $3,000, Oakley is usually the answer, but you should expect to be renting from an individual owner rather than a leasing office.

For context, a one bedroom in Concord runs roughly $1,800 to $2,100 and in Walnut Creek roughly $2,400 to $2,530. So moving from Walnut Creek to Antioch saves you somewhere around $600 a month. That is the number the whole decision turns on, and the rest of this guide is about what that $600 actually buys and costs.

The BART map misleads people, and it matters

BART shows a line reaching Antioch. That line is not regular BART. The segment past Pittsburg/Bay Point is eBART, a diesel multiple unit shuttle running in the median of Highway 4, and it only has two stations: Pittsburg Center and Antioch. It opened in 2018.

To get to San Francisco you ride the shuttle to a transfer platform just east of Pittsburg/Bay Point, get off, walk across the platform, and board a real BART train. The transfer itself is quick and the platforms are designed for it, but it is a transfer, and if you miss the connection you are waiting. Antioch to Pittsburg Center is about 7 minutes, Pittsburg Center to the transfer platform about 3 more.

End to end, Antioch station to Embarcadero runs about 1 hour 10 minutes, with trains roughly every 20 minutes. That is before you get to the station. Fares run near $9 each way, so a five day in office week puts you somewhere around $380 to $420 a month in BART fare alone. Check current fares on bart.gov before you budget, since they adjust.

Three things to know before you sign anything based on the commute:

• Brentwood and Oakley have no rail at all. Your nearest station is Antioch, which is a 15 to 25 minute drive depending on traffic, plus parking. Tri Delta Transit runs connecting buses, but plan around driving.

• Antioch station is a park and ride. It was built for drivers, and the lot fills on weekday mornings. Very few rentals are actually walkable to it.

• Driving Highway 4 westbound in the morning is the thing eBART was built to escape. Peak backups routinely push an Antioch to downtown San Francisco drive past 90 minutes. If your plan is to drive, drive the route at 7:30am before you commit.

Antioch caps rent increases. The other three do not.

This is the single most useful thing to know out here, and almost nobody looking from outside the area knows it.

Antioch passed a Rent Stabilization Ordinance effective November 2022. It caps annual rent increases at 3 percent or 60 percent of the San Francisco-Oakland-Hayward CPI, whichever is less. Under the 2026 formula that works out to well under 1 percent. Antioch also has a Just Cause Eviction Ordinance that took effect September 10, 2024.

The coverage rules matter as much as the cap. Antioch's ordinance covers units built before February 1, 1995, and specifically excludes single family homes, condominiums, government owned units, below market rate units, dorms, mobile homes in parks and various care facilities. So an older apartment building in Antioch is one of the more protected tenancies in the East Bay, while a rented house two streets over is not covered at all.

Pittsburg, Brentwood and Oakley have no local rent control. You fall back on California's statewide AB 1482 cap, which is looser and has its own exemptions, including buildings under 15 years old and single family homes owned by individuals who serve the required notice.

Practical version: if you want rent predictability, ask the building's construction year, and weight Antioch apartments accordingly.

The heat is a budget line, not a footnote

East Contra Costa sits outside the coastal influence, and the numbers are not subtle. Afternoons here run 30 to 35 degrees warmer than San Francisco on the same day. Antioch's July average high is around 91. Brentwood has seen forecasts as high as 115 during heat waves.

What this means for you as a renter: air conditioning is not optional, and your summer PG&E bill will look nothing like a San Francisco bill. Before you sign, ask whether the unit has central air or window units, how old the system is, and whether there is any insulation work on record. A cheap one bedroom with a failing AC unit is not cheap in August.

The good news is the Delta breeze. Antioch, Pittsburg and Brentwood sit right in the breeze corridor, and on nights when it kicks in, a 100 degree afternoon can be down near 70 by 9pm. Evenings out here are often better than the forecast suggests.

Neighborhood notes

In Antioch, Rivertown is the historic downtown near the water, with older housing stock, cafes and the most walkable street grid in the city. Lone Tree Valley and the Deer Valley and Country Hills areas in the south are newer, quieter and mostly house rentals near the better rated schools. Mira Vista Hills gives you views and space at mid range prices. The Sycamore Drive corridor is the dense apartment stretch with the city's roughest reputation; the city has been pushing to turn it around and opened a police substation at Sycamore Square in early 2026, but go see it in person at different hours before deciding.

In Pittsburg, Old Town near the waterfront has real character and the newer complexes sit closer to the Highway 4 corridor. In Brentwood, the newer subdivisions on the south and east sides carry the higher prices, and downtown Brentwood is a genuinely walkable small core. Oakley is largely single family throughout.

Running the numbers honestly

The $600 a month you save moving from Walnut Creek to Antioch is real, but so is the $400 a month in BART fare if you commute five days, and so is the summer cooling cost. If you are fully remote or work in the Tri-Valley or Concord, East Contra Costa is one of the strongest value plays left in the Bay Area. If you are in a downtown San Francisco office three or more days a week, do the arithmetic before you fall in love with a listing.

When you search, filter on the things that actually drive cost out here: construction year (for rent cap coverage in Antioch), air conditioning type, and real drive time to the Antioch station at the hour you would actually leave. Iris can search across East Contra Costa listings and the rest of the Bay Area at once, so you can compare what your budget gets you in Antioch against what it gets you in Concord or Hayward before you narrow down.
