Property tax

Mello-Roos in North San Diego County

The most-asked question in 92127, and the one almost no agent site answers — because answering it means reading the County Auditor’s own district list rather than guessing. Below is that list, for all 50 communities we cover, including the seven where the honest answer is “none.”

What is Mello-Roos?

Mello-Roos is an additional property tax levied inside a community facilities district (CFD), used in San Diego County and across California to pay for the schools, roads and parks that a new development required. It is charged on top of the ordinary property tax, it is set per parcel rather than per neighborhood, and it appears as a separate line item on the tax bill.

The name comes from the Mello-Roos Community Facilities Act of 1982, passed after Proposition 13 limited what cities could raise through ordinary property tax. The practical effect for a buyer today: two similar homes on the same street can carry materially different monthly costs, and the difference is invisible in a listing price.

What is the difference between Mello-Roos and an HOA?

In San Diego County, Mello-Roos is a tax and an HOA fee is a private contract. Mello-Roos is levied by a government district, arrives as a line on your county property tax bill, pays for public infrastructure, and normally ends when the bonds are repaid. HOA dues are billed by a private association, pay for shared private property, and do not end. A San Diego County home can carry both, either, or neither — they are unrelated charges, and one is not a substitute for the other.

The differences that change what you actually pay:

  • Who charges it. A community facilities district is a public agency formed by a city, county or school district. An HOA is a private nonprofit corporation governed by its CC&Rs under the Davis-Stirling Act.
  • Whether it ends. Mello-Roos bonds are issued for a fixed term, so the levy has an end date — though districts that fund ongoing services rather than construction can levy indefinitely. HOA dues have no end date at all.
  • Whether it can rise. A CFD's special tax is capped by the formula in the district's own rate and method of apportionment. An HOA board can raise regular dues each year, but California Civil Code §5605 bars an increase of more than 20% over the prior year, or special assessments totalling more than 5% of budgeted expenses, without a member vote.
  • What happens if you don't pay. Unpaid Mello-Roos can be pursued through accelerated judicial foreclosure, which moves faster than ordinary property tax delinquency. An HOA records a lien and can foreclose on that.

Two practical notes. A seller must give you written notice of a continuing Mello-Roos lien under California Civil Code §1102.6b, so it should never be a surprise at closing — ask for it if you have not seen it. And on taxes, treat the two differently: HOA dues on a primary residence are not deductible, and the deductibility of a Mello-Roos levy depends on what it funds, so that one is a question for a CPA rather than for us.

To find out what a specific address carries, use the lookup below for the Mello-Roos side and ask the listing agent for the HOA's current dues, reserve study and pending special assessments.

How much is Mello-Roos in San Diego County?

No single San Diego County figure exists, and any source quoting one for a whole city has not read the county's list. A Mello-Roos amount is specific to the parcel: it varies by district, by improvement area within that district, and by the phase a home was built in. The authoritative number is the line item on that property's tax bill, which names the district and gives a contact number.

What can be published is the rate each district charges for a stated class of home in a stated fiscal year, from the administrator’s own annual report, and when the levy is scheduled to end. Those figures, with their sources, are on the community cost pages: 4S Ranch, Carlsbad, Chula Vista, Del Sur, Encinitas, Escondido, Menifee, Murrieta, Rancho Santa Fe, San Marcos, Santaluz, Santee, Solana Beach, Temecula. For everything else, the administrator can give you the current levy and the remaining term for a specific address; a website cannot.

Which San Diego city has the most Mello-Roos?

San Marcos, by a wide margin. The County Auditor's active FY 2025-26 list carries 91 community facilities districts for San Marcos — more than any other city in San Diego County. Most are separately numbered improvement areas within a small number of parent districts, which is precisely why no single San Marcos figure exists.

Can I get Poway Unified schools without a big Mello-Roos bill?

The city of Poway is where to look. Poway Unified administers 19 active districts, but the bulk of that load sits in the newer 92127 communities the district also serves — Del Sur, 4S Ranch, the Black Mountain Ranch villages — rather than in the older city of Poway itself, which was largely built before those districts were formed.

Same school district, materially different total monthly cost, older housing stock and larger lots in exchange. It is a parcel-level question rather than a guarantee — the tax bill confirms it — but it is real, checkable, and almost nobody spells it out. See the Poway guide.

Want the number for a specific address?

The district administrator can give you the current levy and remaining term once you know which district applies. If you would rather we just pulled it together — the districts, the schools, and what comparable homes on that street actually sold for — send the address.

Source: County of San Diego Auditor & Controller, Active Mello-Roos Districts (CFD) for FY 2025-2026, retrieved 2026-07-25. The Auditor’s list names districts; it does not map parcels. “No district is named for X” is a fact about that list, not a parcel-level guarantee — a homeowner can sit inside a differently-named district. The tax bill is where the truth for a given parcel lives.
