Cottonwood Creek runs through the middle of town, and it is not just scenery. It is the actual boundary between Shasta County and Tehama County, which means a house on one side of a subdivision and a house two streets over can sit in different counties entirely, with different offices holding the paperwork for each. Two properties advertised under the same 96022 ZIP code, sometimes on the same road, can be filed under Shasta County on one listing sheet and Tehama County on the next.
That split is not a quirk you can safely ignore until closing. It touches which listings your search actually turns up, which office you call about your tax bill, and which school your address feeds into. None of it shows up on a portal's headline numbers, and most of it only becomes obvious once you are already deep into a transaction.
The Line Was Drawn Through the Town on Purpose
Cottonwood started as a stagecoach settlement in 1849. When the California legislature carved Tehama County out of the southern half of Shasta County in 1856, lawmakers picked Cottonwood Creek as the new dividing line. The creek already ran through the settlement, so the decision split the town in half rather than routing around it. Cottonwood has been a two-county town by design ever since, not by accident of later development.
That history matters today because the administrative machinery built around county lines, MLS territories, assessor's offices, school attendance boundaries, has never had a reason to reconcile itself. Each county built its own systems, and Cottonwood happens to sit in the overlap.
Two MLS Feeds, One ZIP Code
Here is the part that catches people off guard fastest. Listings in Cottonwood are fed into search results by two separate REALTOR associations, the Shasta Association of REALTORS® and the Tehama County Association of REALTORS®, each running its own IDX data feed. A brokerage site or agent search tool that only pulls from one association's feed will not necessarily show you the other half of active Cottonwood inventory, even though both halves carry the same 96022 address.
You can see the split in how listings are actually tagged. In recent inventory, addresses like El Camino Drive and Majestic Oak Circle are filed under Shasta County, while Farquhar Road, Sunset Hills Drive, and Benson Road are filed under Tehama County, all within the same town and the same ZIP. If your search only checked one association's data, you would never know the other properties existed.
Before you commit to a search tool or an agent, it is worth asking a direct question: does your access include both the Shasta Association of REALTORS® feed and the Tehama County Association of REALTORS® feed, or just one? For a buyer trying to see everything on the market, that answer determines whether you are looking at half the town or all of it.
Different Offices Hold Your Parcel's Paperwork
Once you have identified a specific property, the county line follows you into escrow. Shasta County parcels are tracked through the Shasta County Assessor/Recorder, using a twelve-digit assessment number formatted as book, page, and parcel. Tehama County parcels run through a separate Assessor's office, currently headed by Burley Phillips, and a separate Treasurer-Tax Collector's office located at 444 Oak Street in Red Bluff.
The timing differs too. Tehama County mails its annual secured tax bill by November 1, with stubs for both installments included on that single mailing. Shasta County sends assessment notices each spring, ahead of its own billing cycle. If your parcel changes hands mid-year, knowing which county's calendar applies affects how taxes get prorated at closing and what the new owner should expect to receive, and when.
| Shasta County side | Tehama County side | |
|---|---|---|
| Assessor | Shasta County Assessor/Recorder | Tehama County Assessor (Burley Phillips) |
| Tax Collector | Shasta County Tax Collector | Tehama County Treasurer-Tax Collector, 444 Oak Street, Red Bluff |
| Annual bill mailed | Spring assessment notice | By November 1, both installment stubs included |
| Parcel ID format | 12-digit book-page-parcel number | County-assigned Fee Parcel Number |
Anyone in escrow on a Cottonwood property should confirm early which office actually holds the file. The Shasta County Tax Collector's overview page and the Tehama County Treasurer-Tax Collector's office are both public resources, and pulling the correct one before closing saves a scramble afterward.
Why Two Sources Can't Agree on the Tax Rate
This is where the split shows up in numbers, and it explains a discrepancy a careful buyer will eventually notice. One property tax database, drawing its records from the Shasta County assessor's rolls, lists Cottonwood's median effective property tax rate at 1.07 percent. A separate national property data provider, drawing its Cottonwood figures from Tehama County's assessment records instead, lists the same town's effective rate at 0.9 percent.
Both numbers are accurate. Neither one is describing the whole town. Each is describing whichever half of Cottonwood that particular database happened to pull its records from, and most aggregator tools do not disclose which county's rolls they used. If you search "Cottonwood property tax rate" and get two different answers from two reputable-looking sites, this is why. The fix is not to average the two figures. It is to pull the actual assessment for your specific parcel from the county that holds it, using either the Shasta County Assessor's online assessment inquiry or the Tehama County Assessor's parcel lookup, rather than trusting a ZIP-code-level estimate from either county alone.
What Doesn't Change at the Creek
Given how much splits along the county line, it is worth naming the one major cost item that does not. Standard escrow and title fee customs in California are set at the county level, and for both Shasta and Tehama, the custom is identical: escrow charges and title fees are typically split fifty-fifty between buyer and seller, with the seller customarily covering the county transfer tax. A buyer bracing for a materially different closing statement depending on which side of the creek they land on will not find one, at least not because of this particular line item.
That single point of consistency is useful context. It means the friction in a Cottonwood transaction is administrative, not financial in the closing-cost sense. The work is in confirming which office to call and which records to pull, not in negotiating a different fee structure because your parcel happens to sit twenty feet east of the creek instead of west.
Schools Follow the County Line Too
Attendance boundaries split along the same divide. Parcels on the Shasta County side generally feed into Cottonwood Creek Charter, North Cottonwood Elementary, and West Cottonwood Jr High. Parcels on the Tehama County side generally feed into Evergreen Elementary and Evergreen Middle. Boundaries can shift, and a specific address should always be confirmed directly with the district office rather than assumed from the mailing address alone. The point here is not which schools are better. It is that the assignment itself depends on which side of the creek the parcel sits on, one more place where the county line has a practical effect that a ZIP-code search will not reveal.
What to Check Before You Write an Offer or Sign a Listing Agreement
A few minutes of verification up front avoids most of the friction described above.
- Pull the parcel on the county GIS parcel viewer for both Shasta and Tehama County to confirm which county actually holds it, rather than assuming from the street or the ZIP.
- Ask your agent directly whether their MLS access includes both the Shasta Association of REALTORS® feed and the Tehama County Association of REALTORS® feed.
- Identify the correct assessor and tax collector office for the parcel before escrow opens, so the tax proration schedule matches the county's actual billing calendar.
- If school assignment matters to your household, confirm the current attendance zone with the district office rather than relying on the address alone.
As of early August 2026, active Cottonwood listings numbered in the mid-fifties across both sides of the creek. That is a small enough market that missing half of it because your search tool only covers one county's MLS feed is a real risk, not a theoretical one.
Frequently Asked Questions
Does closing cost more on one side of the creek than the other? No. Escrow and title fee customs in both Shasta and Tehama County follow the same fifty-fifty split between buyer and seller, with the seller customarily covering the county transfer tax. The county line affects which offices handle your paperwork, not the standard cost-sharing structure.
Will my agent automatically show me every Cottonwood listing? Only if their MLS access includes both the Shasta Association of REALTORS® and the Tehama County Association of REALTORS® feeds. It is a fair question to ask directly before you start a search.
How do I find out which county my specific parcel is in? The county GIS parcel viewer for either Shasta or Tehama County will show the boundary line and confirm which side a given address falls on. This is worth checking before you write an offer, not after.
Cottonwood rewards a buyer or seller who checks the county line before checking the price. If you are weighing a purchase or a listing here and want someone who already knows which office to call, reach out to Monet Templeton to book an appointment or request a home valuation.
