Every East Dublin listing carries a Mello-Roos figure pulled straight from the seller's most recent property tax bill. That number is accurate. It is also, by the City of Dublin's own admission, not the number a buyer or seller should be relying on to understand what they're actually signing up for.
Here's the friction that catches people mid-escrow: a seller in Dublin Ranch or Positano hands over last year's tax bill for the disclosure packet, the buyer's lender plugs that same figure into a debt-to-income calculation, and everyone treats it as fixed. It isn't. Every Community Facilities District in Dublin has a maximum special tax rate written into its formation documents, and the amount actually levied in any given year can sit below that maximum, then move toward it without a new vote or a new disclosure trigger. The City of Dublin's own FAQ page is explicit that a buyer or seller should not rely on the amount shown on the property tax bill for disclosure purposes, precisely because that bill only ever shows what was billed this year, not what the parcel is obligated to pay at the ceiling.
That gap between "levied" and "maximum" is the thing worth understanding before you write an offer on anything east of Tassajara Road.
Where the CFDs Actually Sit in Dublin
Dublin's newer growth was financed the way most fast-growing California cities financed it after Proposition 13 capped base property tax revenue: through Community Facilities Districts that let master-planned tracts pay for their own roads, parks, and services rather than waiting on general fund dollars. The city currently administers several of these districts, and they are not interchangeable.
| CFD | What it funds | What's documented |
|---|---|---|
| No. 2015-1, Dublin Crossing ("The Boulevard") | Facilities: roads, parks, and infrastructure for the Boulevard master plan | Levied roughly $3,912 to $5,830 per year in FY 2024-25 depending on home size, with escalation of up to 2 percent annually and no special tax after fiscal year 2050-51 |
| No. 2017-1, Dublin Crossing Public Services | Ongoing city services within Dublin Crossing | A separate line item layered on top of the 2015-1 facilities charge, not a replacement for it |
| No. 2023-1, East Ranch | A facilities tax covering city capital improvements plus Dublin San Ramon Services District and Zone 7 impact fees, and a separate services tax for ongoing maintenance | Formed by City Council on December 5, 2023; no bonds had been issued as of formation, with the city projecting issuance in 2025, a date that has since passed, so current bond status is worth confirming directly with the city |
Notice that Dublin Crossing alone carries two separate CFDs stacked on the same parcel. That's not unusual for East Dublin. It's also exactly the kind of detail that gets missed when a buyer only looks at the single "Mello-Roos" line summarized on a listing sheet instead of the actual county tax bill, which breaks each CFD out separately.
Those FY 2024-25 figures for CFD No. 2015-1 are also two escalation cycles removed from today. With the district permitted to raise its levy up to 2 percent a year, the current fiscal year's actual charge on a given parcel is likely somewhat higher than the range documented for FY 2024-25, which is one more reason to pull the current bill rather than lean on a figure that's already aging.
The Gap Between "Levied" and "Maximum"
Here's where the city's own language matters. Per Dublin's FAQ, all CFDs have a maximum special tax amount that cannot legally be exceeded, but the amount levied in any single year can come in below that ceiling. The levy can move up or down year to year, as long as it never crosses the max. That flexibility is normal financial management for the district. It also means the figure on this year's bill tells you what you're paying now, not what you could be asked to pay under the same recorded obligation.
There's a second layer worth knowing. Dublin's CFDs typically carry two distinct kinds of special tax: a facilities tax tied to bond repayment, which has a hard end date once the bonds are retired, and a services tax funding ongoing maintenance, which has no such expiration and can be levied indefinitely. A parcel's facilities charge might sunset in 2050. Its services charge might not sunset at all. Reading only the total on a tax bill collapses both of these into one number and erases the distinction that actually determines your long-term exposure.
And the obligation itself doesn't reset when a home changes hands. The tax lien is recorded against the parcel, not the person who owned it when the district was formed, the same way HOA dues stay attached to a unit regardless of who was on the board when the association started collecting them.
What This Costs in Real Terms
Lenders who regularly close CFD-encumbered deals in California describe the practical effect this way: effective property tax rates in CFD-heavy zip codes, combining the base 1 percent levy with Mello-Roos and other local add-ons, commonly run in the 1.5 to 1.7 percent range of purchase price, compared with roughly 1.1 to 1.3 percent in areas without an active district. On a home purchased in the mid-$1 millions, that spread is not a rounding error. It shows up every month in the housing payment a lender qualifies against, and it shows up every year on the bill whether or not the district happens to be levying near its floor or its ceiling that particular cycle.
Why West Dublin and East Dublin Price Differently for the Same Square Footage
This is the part that changes how you should compare two listings that otherwise look identical on paper. Most of the master-planned communities carrying active Mello-Roos bonds today sit in East Dublin: Dublin Ranch, Positano, Tassajara Hills, and the Dublin Crossing tract chief among them. These are also some of the newest housing stock in the city, with the newest school construction and the least deferred maintenance.
West Dublin tells a different story. Schaefer Ranch, the 302-home hillside subdivision built by Discovery Homes starting in 2008, predates the current wave of CFD-funded master planning by more than a decade. A three-bedroom in Schaefer Ranch and a three-bedroom in Positano can list within a few thousand dollars of each other and still carry a real, ongoing cost difference that never appears in the asking price, because one comes with a recorded special tax obligation and the other largely doesn't. That difference only surfaces once someone pulls the actual county tax bill or the preliminary title report, which is often later in the process than either party expects.
The Next Wave: Dublin Centre Adds Another Corridor to Watch
Landsea Homes broke ground on Dublin Centre, marketed as "The DC," in October 2024, at the northeast corner of Tassajara Road and Dublin Boulevard. The 500-home project spans three blocks along Tassajara Road and is, according to the company's California division president, the largest master-planned community Landsea has built from the ground up in the Bay Area. The Dublin Planning Commission approved it within the Eastern Dublin Specific Plan area, the broader growth umbrella that has guided most of the city's master-planned expansion east of downtown over the past two decades.
That approval history doesn't tell you whether Dublin Centre carries its own CFD. It does mean anyone touring new construction in that corridor should ask the question directly rather than assume the answer based on an older tract nearby. New districts get formed and their bonds get issued on their own timeline, and a project that broke ground less than two years ago may not have the kind of public CFD documentation a decade-old tract already has on file.
Before You Write the Offer or Sign the Disclosure
A few concrete steps close most of the gap between what a listing implies and what the parcel actually owes:
- Pull the current Alameda County secured tax bill using the parcel's APN and look for each special tax line separately, not just a combined total.
- Request the Notice of Special Tax and the CFD's Rate and Method of Apportionment, which is the document that actually states the maximum allowable levy, not just this year's amount.
- If a prepayment payoff figure matters to your numbers, contact the city's CFD administrator, Goodwin Consulting Group, directly for the current payoff calculation rather than estimating from the tax bill.
- Ask your lender in writing how they're treating the special tax in your debt-to-income calculation, since underwriters increasingly want the RMA on file, not just the bill.
- If there's an HOA on top of the CFD, as there often is in East Dublin, request the resale packet and check whether it references any CFD funds or pending assessments layered onto what the county is already collecting.
A Few Direct Questions
Can a Mello-Roos tax be paid off early? In many Dublin CFDs, yes. The city directs prepayment questions to its CFD administrator, Goodwin Consulting Group, who can provide the current payoff figure for a specific parcel.
Is the Mello-Roos amount the same across all of East Dublin? No. Each CFD sets its own rate structure through its Rate and Method of Apportionment, and the amount is parcel-specific, not a flat citywide number.
Does a services-only special tax ever expire? Not necessarily. Facilities taxes tied to bonds end once the bonds are repaid, typically after 25 to 30 years, but services taxes that fund ongoing maintenance can be levied indefinitely under the district's rules.
