How to Read a Property Tax Bill in Contra Costa County
The number you don’t want to miss before making an offer
When purchasing a home, the monthly payment matters just as much as the purchase price—sometimes more.
Part of that payment is your property tax bill.
In Contra Costa County, that bill generally has two main components.
Ad valorem taxes, typically shown on the right side, are percentage-based and are usually reassessed based on the purchase price.
Special assessments, often listed on the left, are fixed amounts tied to the property itself.
Together, they shape your true cost of ownership—and ultimately influence your budget and how much you choose to pay.
Not all properties are the same.
Property taxes can vary significantly from one neighborhood to another—and even from one property to the next.
Some homes carry higher special assessments, Mello-Roos, or bond obligations that increase the overall monthly expense.
Others may have lower assessments—creating a meaningful difference over time.
Understanding this early matters.
