What to Know About Property Taxes in Danville, CA for 2026

Homes in Danville, CA are moving fast right now. As of mid-2026, the median sale price in the Danville, CA housing market is around $2,010,000, and listings are spending roughly 22 days on the market before they're gone.

At that price point, property taxes aren't a footnote - they're a real line item in your monthly budget. Understanding how Contra Costa County builds that bill will save you from some genuinely unpleasant surprises after closing.

Property Tax Rates in Danville, California

The effective property tax rate in Danville generally falls between 1.11% and 1.17% of a home's assessed value, depending on whether you're in the 94506 or 94526 ZIP code. The difference comes down to local school district levies and municipal bonds, which vary by neighborhood.

That rate is actually lower than the overall Contra Costa County median of 1.31%, though it runs noticeably higher than the California state average. The exact amount on any given parcel depends on the specific voter-approved measures attached to that address.

Comparing Danville to the State Average

California's overall effective tax rate is around 0.71% - lower than the national average. Danville homeowners pay a higher percentage because of local bonds passed to fund regional infrastructure and schools.

Even within Contra Costa County, rates swing widely from town to town, with most homeowners paying somewhere between 1.10% and 1.40% overall. That puts Danville right near the lower-middle end of the county range.

How Rates Change Over Time

The base rate is fixed by state law, but the effective rate moves when local voters approve new bonds. When old bonds are paid off, those charges drop off your bill.

Your rate isn't a permanent number. It will shift slightly from year to year depending on which local assessments are currently active for your specific Danville neighborhood.

Calculating Your Danville Property Tax Bill

California property taxes start with a base rate of 1% of the home's assessed value. Local municipalities then add voter-approved bonds and special assessments on top of that to reach your actual bill.

For a new buyer, the assessed value is typically the purchase price. Buy a house for $2,010,000, and the county tax assessor uses that figure as your starting baseline.

Assessed Value Under Proposition 13

Proposition 13 caps how much your assessed value can increase each year. Regardless of how fast market values climb, your taxable baseline is legally restricted from keeping pace.

That's genuinely good news for long-term owners. Even if your home's market value doubles over a decade, your tax bill grows by only a small, capped margin annually.

Estimating Taxes on a Typical Danville Home

Apply the average effective rate to your purchase price and you get a working estimate. On a home bought at the current median of $2,010,000, a 1.17% effective rate puts the annual tax bill at roughly $23,517.

That's a starting point, not a guarantee. The exact figure depends on the specific bonds tied to the property address, so always pull the actual tax records for any home you're seriously considering.

Estimating Taxes by Property Address

A generalized rate gives you a ballpark. The actual address gives you the real number.

Contra Costa County maintains public tax records showing the exact levies on every parcel. With 93 homes currently sitting in Danville's active inventory, you can pull the past tax bills for any listing before you make an offer - which shows precisely which local bonds and special assessments are active for that address.

Using Assessed Value for Estimates

The previous owner's tax bill is based on their assessed value, not yours. If they bought the home twenty years ago, their bill will look dramatically lower than what you'll owe.

To estimate your own number accurately, find the total effective tax rate shown on their bill and apply it to your expected purchase price. You keep the local bond picture; you just update the baseline.

Searching by Danville ZIP Codes

Tax rates can differ between the 94506 and 94526 ZIP codes - some properties fall under different school district boundaries or community facility districts depending on exactly where they sit. Narrowing your search by ZIP code helps you catch those differences before you're in contract. Your agent can also pull the specific tax profile for any listing you tour.

Finding and Paying Your Contra Costa County Tax Bill

All property taxes in Danville are handled at the county level. The Contra Costa County Assessor determines your property's value; the Tax Collector handles the billing and collects payment.

You can view your bill, check your assessed value, and pay directly through the county's official online portal. Many buyers also set up their property taxes to be paid automatically through an escrow account managed by their mortgage lender, which takes the scheduling pressure off entirely.

Accessing Property Tax Records Online

Property tax records are public in California. You can look up any Danville address on the county website to see the current assessed value, the breakdown of local bonds, and the payment history.

Worth doing during due diligence - it confirms there are no delinquent taxes tied to the property that would need to be resolved before closing.

Important Payment Due Dates

Contra Costa County splits the annual bill into two installments. The first is due November 1 and becomes delinquent if you haven't paid by December 10. The second is due February 1 and goes delinquent after April 10.

Miss either deadline and you're looking at an immediate 10% penalty. Put those dates somewhere you'll actually see them.

Ways to Lower Your Danville Property Tax Burden

California offers several programs that can reduce what you owe. These exemptions work by lowering your assessed value, which brings the final bill down with it.

None of them are applied automatically. You have to apply through the county assessor's office, and that's worth doing sooner rather than later after you close.

Proposition 19 Rules for Older Adults

Proposition 19 allows eligible homeowners over the age of 55 to transfer their current property tax base to a new home. You can sell your long-time residence and buy in Danville without facing a sudden, steep tax increase tied to the new purchase price.

The new home can be equal to or greater in value than the old one, though adjustments apply if it's more expensive. For long-term California residents thinking about downsizing or relocating, this is a meaningful benefit.

The Standard Homeowner Exemption

The California Homeowners' Exemption knocks $7,000 off the assessed value of your primary residence. The dollar savings per year are modest, but there's no reason to leave it on the table.

You only need to apply once. It stays on your record as long as the home remains your primary residence.

Special Assessments and New Construction Taxes

Beyond the standard 1% rate and local bonds, some properties carry additional charges for specific community improvements. This comes up most often in newer developments where infrastructure had to be built from scratch.

If you're looking at new construction or recently developed neighborhoods in Danville, pay attention to these additions. They're billed alongside your regular property taxes, but they function differently than standard bonds.

Assessing Newly Built Homes

When you buy a newly constructed home, the initial tax bill may only reflect the value of the vacant land. Once the county assesses the finished structure, you'll get a supplemental tax bill covering the difference.

Budget for that bill during your first year of ownership. It often arrives months after closing and is rarely covered by the initial funds sitting in your mortgage escrow account.

Mello-Roos and Community Facilities Districts

Some Danville neighborhoods fall within Community Facilities Districts - commonly called Mello-Roos districts. These are special tax assessments used to fund local infrastructure like roads, schools, and parks.

Mello-Roos taxes aren't based on your home's assessed value; they're typically a flat fee based on the size or type of the property. Sellers are required by law to disclose if a home carries a Mello-Roos assessment, so you shouldn't be caught off guard - but make sure you ask.
