Brea

Brea sits in the northeastern corner of Orange County, where Orange, Los Angeles and San Bernardino counties meet. The city covers about 12.7 square miles between La Habra, Fullerton, Placentia and Yorba Linda, with Chino Hills State Park to the east. The Orange Freeway (SR-57) runs north-south through the middle of town. Housing ranges from older streets and new apartments near Downtown and the Brea Mall to planned communities and hillside homes, and the city's oil history and wildfire maps shape what you can build.

It tends to suit buyers who want SR-57 access toward Los Angeles County or central Orange County, who want a townhome or condo near shopping, or who want a hillside home and can plan for fire-zone rules, insurance and special taxes.

Neighborhoods and housing in Brea

The California Department of Finance estimated 18,731 housing units in Brea on January 1, 2026: about 53 percent detached single-family homes, about 9 percent attached single-family units such as townhomes, about 32 percent in buildings with two or more units, and 1,011 mobile homes.

Downtown and the Brea Core

Downtown Brea, along the Brea Boulevard and Birch Street corridors, is the city's restaurant, movie and live entertainment district, linked by Birch Street to the Civic Center and Brea Mall area. In June 2026 the City Council approved the Brea 2050 Focused General Plan Update, which replaces the 2003 General Plan, along with a new Brea Core Specific Plan. The core is the central area bounded generally by Lambert Road, Imperial Highway (SR-90), Berry Street, SR-57 and Associated Road, and the plan allows up to 4,752 homes there. Projects already approved include a 380-unit apartment building at the Brea Mall and 179 townhomes north of the Brea Plaza shopping center. Twenty historic properties hold Mills Act contracts, which lower property taxes in exchange for preservation; ask a seller for a copy.

Planned communities

The city governs several planned communities through specific plans, including Olinda Ranch and Tonner Hills, and its special tax reports name newer developments such as Blackstone, La Floresta and Central Park Village. Ask whether an HOA and CC&Rs apply and read them for dues and maintenance duties; the city says CC&Rs for projects built in the past 20 years should cover upkeep of any required public art.

Oil fields, methane and old wells

The city's combustible soil-gas guideline explains that Brea is bounded by the Coyote petroleum reservoir to the south and the Brea-Olinda reservoir to the north, and that drilling left hundreds of well casings. Land over these reservoirs, plus 300 feet around them, is treated as an impacted area where new construction, including additions and remodels, needs a soil-gas investigation and any required mitigation. Abandoned wells that do not meet current state standards must be re-abandoned before building permits are issued, and homes cannot be built over or within 10 feet of a well casing. The city asks ADU applicants to check the state's CalGEM well map and to call the Brea Fire Department if a well is on or next to the property.

Getting around

• SR-57: the Orange Freeway runs north into Los Angeles County and south toward SR-91, where the 91 Express Lanes require a FasTrak transponder.
• East-west roads: Imperial Highway (SR-90), Lambert Road and Carbon Canyon Road (SR-142), which continues east through the canyon toward the San Bernardino County line.
• Rail: Brea has no train station. The Fullerton Transportation Center, to the southwest, has Metrolink and Amtrak service; see our Fullerton guide.
• Bus and airports: OCTA runs four bus routes with 67 stops in Brea. Commercial flights leave from Ontario International, John Wayne, Long Beach and LAX.

Schools

Most Brea addresses are served by the Brea Olinda Unified School District, which has a School Locator on its enrollment site. Placentia-Yorba Linda Unified also serves portions of Brea and offers a Find Your School lookup. Confirm the exact address with the district rather than relying on the ZIP code, and use the California School Dashboard for data on any public school.

Parks, beaches and things to do

• Carbon Canyon Regional Park: a 131-acre county park at Carbon Canyon Road and Valencia Avenue.
• Olinda Oil Museum and Trail: at 4025 Santa Fe Road, with a working oil well drilled in 1898 and a 1.9-mile hiking trail.
• The Tracks at Brea: a linear park of about four miles on a former railroad, with a paved bikeway and a separate footpath.
• City parks and golf: City Hall Park with the Brea Plunge pool, Brea Sports Park, Wildcatters Park, and the Brea Creek and Birch Hills golf courses.
• Art in Public Places: since 1975, private developers have commissioned more than 185 outdoor sculptures for their properties, which owners maintain. Brea is inland, so beach trips mean a freeway drive.

Local rules and costs to know

• Utilities: Southern California Edison provides electricity and SoCalGas provides gas. The city bills water, sewer, trash, street sweeping and urban runoff together, with trash collected by Republic Services. The Yorba Linda Water District serves portions of Brea, so confirm the water provider for the address.
• Short-term rentals: Ordinance 1270, adopted January 20, 2026, created a pilot program through December 31, 2029, with up to 100 licenses split among three city sectors and awarded by lottery. Applicants must own the property, get HOA approval where one exists and have no open code violations. Stays have a two-night minimum and a 10 percent transient occupancy tax, and ADUs and junior ADUs are not eligible.
• ADUs: rules are in Chapter 20.52 of the zoning code. Under the city's Pre-Approved ADU Plans Program, owners can get plans from designers on the city's list but still submit an updated site plan for plan check, and new ADU buildings need a soil test and are subject to the methane guidelines. See our ADU guide.
• Fire hazard zones: CAL FIRE's March 24, 2025 map for Brea shows Very High zones across much of the hillside land in the north of the city, reaching east to the Carbon Canyon Road area, and the Fire Department adopted the updated maps in 2025 with new brush clearance standards. Our homeowners insurance guide covers what a zone means for coverage.
• Property taxes and Mello-Roos: Brea has six community facilities districts. Two are bonded (CFD 1997-1, Olinda Ranch, and CFD 2008-2, Brea Plaza), and four fund public safety services, and in some cases maintenance, in newer developments (CFD 2008-1, Blackstone; CFD 2011-1, La Floresta; CFD 2013-1, Taylor Morrison; and CFD 2013-2, Central Park Village). Look up Mello-Roos on the tax bill, read our property tax guide and run the property tax calculator.

Buying in Brea

• Before you plan an addition or ADU, check the CalGEM well map and ask the city whether the lot is in the soil-gas impacted area, which adds testing and possible mitigation.
• In the northern hills, check the fire hazard map and get insurance quotes early in your contingency period.
• Read the tax bill for CFD special taxes, and read HOA documents for dues, reserves and maintenance duties.
• Confirm the water provider and school district for the exact address.
• Do not count on short-term rental income: licenses are capped, awarded by lottery and tied to a pilot that ends in 2029.

Selling in Brea

• If the home is in a High or Very High zone, request a Defensible Space Disclosure Inspection from the Brea Fire Prevention Bureau before you list; the documentation goes to the buyer before closing.
• Order the Natural Hazard Disclosure report early, and see our seller disclosure guide for what else to disclose.
• Gather permits and any well abandonment or soil-gas mitigation records for past additions.
