The La Habra Zip Code That Pays Two Different Property Tax Bills

If you search for homes in "La Habra," the results come back looking like one market. Same zip code, same city name stamped across every listing, same school ratings pulled from the same database. What that search box will not tell you is that some of those addresses are assessed by the Los Angeles County Tax Assessor and some by Orange County's, that a buyer on one side of the line can finance conventionally while a buyer half a mile away needs a jumbo loan, and that the county line running through this area was taken seriously enough that a school district once held a public vote to move itself across it.

None of this shows up in a portal filter. It shows up in escrow.

A School District That Had to Vote Its Way Into a Different County

Lowell Joint School District serves roughly 3,000 K-8 students across pieces of La Habra, La Habra Heights, and Whittier. For most of its history, the district answered to the Los Angeles County Office of Education, the same office that oversees Whittier and La Habra Heights. The catch: three of Lowell Joint's five elementary schools sit in Orange County, and about 98 percent of its eighth graders go on to Fullerton Joint Union High School District, which is an Orange County district.

In March 2020, more than 70 percent of Lowell Joint voters approved Measure O, a ballot measure authorizing the district to leave the Los Angeles County Office of Education and join Orange County's instead. The transfer took effect July 1, 2021, and it was the first time in California history that a school district changed counties through a ballot measure. The district's superintendent at the time said the move would save around $250,000 a year in operating costs by letting Lowell Joint tap into Orange County's legal and fiscal services instead of Los Angeles County's.

Families didn't do this for convenience. They did it because the county line was creating real friction, coordinating grants, aligning curriculum, and routing kids into a high school system that answered to a different office entirely. If a public agency needed a formal vote to sort out which side of that line made sense, it's worth asking what the line is doing to a private real estate transaction that never gets a vote at all.

One Zip Code, Two Property Tax Bills

Here's where it gets concrete. A property tax research platform that tracks California assessor records lists two separate entries under the name "La Habra." One groups parcels under Los Angeles County and reports a median effective tax rate of 1.18 percent with a median annual bill of $6,767. The other groups parcels under Orange County and reports a median effective rate of 1.16 percent with a median annual bill of $4,781. Same city name on the label. Different county doing the assessing, different bill in the mailbox.

This isn't a data error. La Habra's own boundary description notes a small unincorporated pocket of Los Angeles County sitting right at the city's northeast edge, with La Habra Heights bordering it directly to the north. The 90631 zip code stretches across incorporated La Habra, incorporated La Habra Heights, and that unincorporated sliver, which means a piece of mail addressed "La Habra, CA 90631" doesn't actually tell you which county's assessor calculated your bill.

The practical difference goes beyond the dollar amount. Los Angeles County sends assessment notices each spring, typically reaching mailboxes by mid-April. Orange County runs its own calendar, with a formal appeal deadline of December 1 each year. If you're disputing an assessment, you're not just filing a different form. You're working against a different clock, at a different office, with a different appeals process entirely.

What the Price Gap Is Actually Paying For

Zillow's home value index put La Habra's typical home value at $796,902 as of June 2026, down 0.2 percent over the past year. La Habra Heights, using the same index and the same reporting window, showed a typical home value of $1,405,371, up 2.5 percent year over year. That's not a modest premium. It's nearly double.

The instinct is to read that gap as prestige. The more useful read is infrastructure. La Habra Heights is zoned for roughly one-acre lots, has no sidewalks or curbs on most streets, and runs almost entirely on private septic systems rather than public sewer. La Habra proper is tract housing on public sewer with conventional lot sizes. A buyer comparing the two isn't really comparing two versions of the same product. They're comparing a suburban house to a rural parcel that happens to share a hillside and a name.

Pace backs this up. Around the same window, La Habra homes sold in an average of 38 days, with 90 homes changing hands in June 2026 alone. The most recently published data for La Habra Heights, covering December 2025, showed homes taking a reported 86 days to sell, more than double. Bigger lots, private infrastructure, and a smaller buyer pool willing to take on well or septic maintenance all slow a sale down, regardless of how strong the broader market looks.

Where the Financing Splits

California's 2026 conforming loan limit for this region sits at $1,249,125. La Habra's typical home value sits comfortably below that line, which means most buyers there are financing conventionally, with the standard down payment ranges and underwriting timelines that come with it.

La Habra Heights' typical value sits above that line. A buyer there is very likely stepping into jumbo territory, which usually means a larger down payment, tighter reserve requirements, and a narrower pool of lenders willing to write the loan. That's part of why the days-on-market gap between these two markets is as wide as it is. It's not only that Heights buyers are pickier about acreage and privacy. It's that fewer buyers qualify for the loan in the first place.

If you're preapproved for a conventional loan based on a search for "La Habra" homes, that preapproval may not transfer the moment a listing crosses into the Heights. Worth confirming with your lender before you fall for a hillside view.

Bring the Septic Contractor Before You Bring an Offer

La Habra Heights' own city government publishes a septic systems page laying out when an existing system needs evaluation before a sale or remodel can proceed. A qualified septic contractor has to assess the system if:

• Prior plans exist but show the system is older than 15 years
• Prior plans exist but don't match the home's current floor plan
• No prior plans exist for the system at all

If public sewer runs within 200 feet of the property, the county won't issue a permit to repair a failing septic system. Instead, the homeowner is required to connect to the sewer line when the system fails. That's a meaningful cost and timeline difference for anyone assuming they can simply patch an aging leach field and move on.

None of this exists in La Habra proper, where public sewer is standard and septic contingencies simply don't come up. A buyer moving between these two markets in the same weekend of touring should expect a completely different inspection checklist depending on which side of the line the house sits.

What This Means If You're Comparing Both

The name "La Habra" is doing double duty on every portal search, and the line between the two places it describes isn't visible in a listing photo or a price filter. It shows up in which county's assessor calculates your bill, whether your lender treats your loan as conventional or jumbo, whether your inspection period includes a septic evaluation, and even, as Lowell Joint's voters proved, in which office decides how your kids' school district is funded.

If you're comparing a home in La Habra to one in La Habra Heights, the median price difference is real, but it's telling you about land, infrastructure, and financing tier more than it's telling you about which is the "better" address. Price the property you're actually looking at, not the zip code it shares with its neighbor.

FAQ

Is La Habra Heights considered part of La Habra? No. They are two separately incorporated cities. La Habra sits in Orange County. La Habra Heights sits in Los Angeles County. They share a border and a name, not a government.

Will a standard property search flag which county an address is in? Not reliably. Portal listings are typically organized by city name and zip code, not by county line, so a search for "La Habra" can surface listings from both cities without distinguishing them. Confirming the county through the assessor parcel number before writing an offer is worth the extra step.

Does the county line affect school assignment too? It can. Lowell Joint School District serves portions of both cities, along with Whittier, and feeds into Fullerton Joint Union High School District regardless of which county a student's home sits in. Attendance boundaries are address-specific, so confirming directly with the district is the reliable way to know.
