Source: California Debt and Investment Advisory Commission (CDIAC) — Mello-Roos CFD Yearly Fiscal Status Reports. Bond debt is principal outstanding; “annual special tax” is the amount levied for the year; “% unpaid” is the share of that levy still unpaid (a delinquency signal). Self-reported by issuers; verify against your tax bill and the district before relying.
How Mello-Roos works in San Joaquin County
A Mello-Roos special tax is separate from your Proposition 13 ad-valorem tax. It funds a specific district's bonds — new schools, roads, water and sewer, parks — or ongoing services, and it is charged as a flat amount set by each CFD's Rate and Method of Apportionment, not as a percentage of your assessed value. That is why two similar homes in San Joaquin County can have very different total bills: one may sit inside a CFD and the other may not.
Mello-Roos vs. your Proposition 13 tax
The 1% Proposition 13 base plus voter-approved debt is value-based and applies county-wide. A Mello-Roos / CFD special tax applies only to parcels inside the district and is a flat charge. See what Mello-Roos is and how Proposition 13 sets the rest of your bill.

Frequently Asked Questions
What is Mello-Roos in San Joaquin County?
Mello-Roos is a special tax authorized by California's Mello-Roos Community Facilities Act of 1982 (Gov. Code §53311). A Community Facilities District (CFD) — usually a city, school district, or the county — levies it on parcels inside the district to repay bonds for infrastructure or services, billed on top of the 1% Proposition 13 rate as a flat "direct assessment," not based on your home's value. San Joaquin County has 52 reporting CFDs with about $1.54 billion in bond debt outstanding (CDIAC, reporting year 2024-25).
How do I find which Mello-Roos district applies to my San Joaquin County property?
Your Mello-Roos tax appears as a flat line item in the "direct assessments" or "special assessments" section of your San Joaquin County tax bill, usually naming the CFD. Search that name (or the district's purpose) in the list below to identify it. Mello-Roos amounts are set per parcel under each district's Rate and Method of Apportionment, so the exact figure for your parcel is on your bill or from the district.
How much is Mello-Roos in San Joaquin County?
It varies widely by district and parcel — there is no single county rate. Across all 52 San Joaquin County CFDs, about $128 million in special taxes is levied each year. A typical single-family Mello-Roos charge runs roughly $1,500–$5,000 a year, but depends entirely on the CFD and its Rate and Method. Check the district in the table and your own tax bill.
Do San Joaquin County Mello-Roos taxes ever end?
Usually yes. A CFD's special tax is tied to its bonds, so it typically ends when the bonds are repaid — often 20 to 40 years after issuance. The "Final year" column shows each district's latest reported bond maturity. Some CFDs that fund ongoing services rather than bonds can continue indefinitely; check the district's Rate and Method.
What happens if Mello-Roos isn't paid in San Joaquin County?
An unpaid Mello-Roos special tax is a lien and can trigger an accelerated judicial foreclosure — faster than ordinary property-tax delinquency — because bondholders must be paid. In reporting year 2024-25, San Joaquin County CFDs reported about 1,027 delinquent parcels, with roughly 0.7% of the annual special tax left unpaid. Districts with a high unpaid share are flagged in the table.
