Bond Measures on Your San Diego Property Tax Bill

Beyond the 1% Proposition 13 base, your San Diego County bill includes a share of the general-obligation (GO) bonds that local voters approved — for schools, community colleges, cities, and health and water districts. There are 320 such bond series county-wide (FY 2025-26), issued by about 43 agencies. Each is a small ad-valorem rate; you pay only the ones for your Tax Rate Area, and they appear inside the "voter-approved debt" portion of your total rate.

Your bill shows a single combined ad-valorem rate, not a line per bond. To see the exact bonds behind your rate, look up your Tax Rate Area in the “what’s in your San Diego property tax” explorer — it now itemizes each TRA’s bonds. The list on this page covers every bond county-wide, searchable by agency, measure letter, or election year.

When a school district, city, or other agency asks voters to approve a GO bond, the county assigns it a ballot letter — Measure A, Measure YY, Prop Z, and so on. If it passes, the agency repays the bond through a small property-tax add-on until the bonds mature. The measure letter and election year here identify exactly which voter decision created each charge on your bill.

Yes. A GO bond rate is levied only until that bond series is repaid — typically 20 to 40 years after it was issued — then it drops off the rate. New voter-approved bonds can be added as districts build more, which is why the voter-approved-debt portion of a rate changes over time.

No. The bonds here are ad-valorem GO bonds — a percentage of your assessed value, approved by the voters inside each issuing district (a school district, city, or college district) by a two-thirds or 55% vote, not county-wide. Mello-Roos is a separate, flat special tax charged only to parcels inside a Community Facilities District. See the San Diego Mello-Roos district list for those.
