Understanding Property Tax in San Diego County
Property tax is a local tax on real estate — land and the buildings on it — and it is the main way San Diego County funds public schools, roads, emergency services, and other county operations. The amount you owe depends on two things: what your property is worth and the combined tax rate set by the local districts that serve it.
In California, the county tax assessor determines each property's assessed value as of January 1st. The average effective property tax rate in San Diego County is about 0.73%. Your bill is the taxable value — the assessed value after any exemptions — multiplied by that rate.
Because rates and exemptions are set locally, two similar homes in different parts of San Diego County can owe very different amounts. The official county records linked on this page show the figures that actually apply to a given parcel.
