When Lennar started selling new homes on Mare Island in the mid-2000s, buyers were told a specific story about the extra tax attached to their property. It was temporary. Development would grow the tax base, the burden would shift to commercial property, and the special assessment would shrink year over year until it barely registered. One early buyer later put it plainly to a reporter: the sales team said the tax was "going to go away in a couple years."
It didn't. The Community Facilities District, or CFD, that Vallejo and Lennar created in 2002 is still active today, and the city's own disclosure paperwork for the newer district says the special tax "will continue indefinitely." If you're comparing Mare Island to the rest of Vallejo right now, that gap between the promise and the paperwork is the thing worth understanding before it's the thing you find out about at disclosure.
A Tax Built to Never Actually Shrink
The mechanics matter more than the headline number. Mare Island's CFD was sized around a Navy-era cost estimate from 2002 for a fully staffed police department and three dedicated fire stations on the island. That staffing never happened. What did happen is a tax structure where residential property owners pay their maximum assessed share first, and only the remainder gets billed to commercial property. In practice, that means any relief from new business activity on the island only shows up after homeowners are already paying in full. Growth was supposed to be the mechanism that shrank the bill. Instead, growth benefits commercial parcels before it touches a single resident's payment.
Residents organized as the Mare Island Special Tax Elimination Alliance ran their own numbers on what this costs and brought them to the council in 2023. Alliance member Daniel Glaze's estimate at the time: an owner of a $500,000 home on the Vallejo mainland pays around $291 a year in CFD-equivalent costs for police and fire, while an owner of an equivalent home on Mare Island pays roughly $2,652. Add it up across the roughly 322 homes on the island and, by Glaze's count, residents had paid something like $56 million in CFD taxes over the prior two decades, on top of standard property and sales taxes. That same year, the city agreed to freeze one of the CFDs, trimming somewhere between $300 and $400 off each payment, but the underlying structure and its "indefinite" language stayed in place.
If you're picturing this as a discount mechanism, where the market prices in the extra tax by lowering what buyers pay for the house itself, the sales data doesn't support that story.
The Redevelopment That Was Supposed to Fix This Just Stopped
The city's long-standing answer to residents asking for relief has been some version of "wait for the Specific Plan." That plan is what's supposed to finally unlock enough commercial development to make the original growth-shrinks-the-tax theory work. As of this spring, the centerpiece of that plan is on hold.
The Connolly Corridor project, a proposed six-block walkable district with retail, a hotel, housing, and open space, was paused in April 2026 while the city and the Vallejo Flood and Wastewater District sort out who pays to fix Mare Island's sewer system. Mare Island Brewing Company founder Kent Fortner, who has redevelopment experience on the island going back to the Coalsheds project he helped refurbish in 2020, told the council he was "extremely disappointed to hear that the Connolly Street corridor is currently at its pause." Previous plans had targeted a 2027 finish for that corridor. A second residential project, Coral Sea Village, a planned 68 single-family homes and 28 multifamily units from Lennar Homes, is also sitting under review pending a director-level decision after an expanded public notice period.
The reason both are stuck is not a market judgment call. It's infrastructure. A Mare Island Infrastructure Assessment completed in October 2025 by engineering firm West Yost & Associates found miles of sewer pipe with structural defects, deteriorated maintenance holes, and cross-connections with the stormwater system, much of it Navy-era infrastructure that hasn't been meaningfully upgraded since the base closed in 1996. Congress has since allocated just over $1 million toward sewer repairs in the 2026 federal budget, which the wastewater district's general manager Mark Tomko called a start on addressing the system's inflow and infiltration problems. A start is not a fix. Back in 2023, city staff told the council they didn't want to touch the CFD tax structure until the broader Specific Plan was finalized, and estimated that plan was still 18 to 24 months away at the time. Three years later, with Connolly Corridor paused and Coral Sea Village still under review, that plan still isn't done.
Why the Premium Holds Anyway
Here's the part that should reset how you think about the tax. Mare Island homes sold for a median of $695,000 in March 2026, down modestly from a year earlier but still well above Vallejo's citywide median in the low $500,000s. That's not a discounted neighborhood. It's a premium one, extra tax included.
The premium has a specific source, and it isn't mysterious once you walk the island. Mare Island's housing stock is newer than most of Vallejo's, largely built around 2005 with two-story Mission Revival and New Traditional designs. Flagship Drive runs along San Pablo Bay views. Crescent Park anchors the community as usable green space. The ferry terminal puts residents on a direct, roughly 60-minute boat ride to the San Francisco Ferry Building, a commute option most of Vallejo doesn't have within walking distance. Repurposed Navy-era buildings now house Mare Island Brewing Company, The Quarters coffee shop, and Savage & Cooke, and St. Peter's Chapel, with its Tiffany stained glass, still hosts concerts and tours.
Buyers are paying for that combination, not despite the tax but alongside it. The market isn't treating the CFD as a price-reducing defect. It's treating the ferry access and the newer construction as worth more than the tax costs. That's a different risk calculation than "am I getting a discount for this," and it's the one worth having with your agent before you write an offer.
What the Newsom Announcement Does and Doesn't Fix
Three days before this was published, Governor Newsom stood on Mare Island and announced $48.5 million in state funding across 18 projects statewide, including $8.2 million for shipbuilding and career development on the island in partnership with Cal Poly Maritime Academy. Of that, $4.3 million is earmarked to convert part of the historic shipyard into an applied research and technology campus, with another $1.4 million going toward workforce development.
That's real investment, and it signals the state sees economic potential in the island beyond housing. It does not touch the sewer capacity dispute holding up Connolly Corridor or Coral Sea Village, and it doesn't change the CFD's language about continuing indefinitely. Treat it as a long-term positive for the island's job base, not as evidence that the tax relief residents have been asking about is imminent.
Before You Write an Offer on a Mare Island Listing
- Ask your agent to pull the current Rate and Method of Apportionment document for the specific CFD tied to the parcel. The amount varies by home size and lot, not just by neighborhood.
- Confirm whether the parcel is inside CFD No. 2002-1, 2005-1A, or 2005-1B. Some carry the partial freeze from 2023, some don't.
- Don't factor in an assumption that the tax drops once Connolly Corridor or Coral Sea Village breaks ground. Both are paused, and even a completed project would require a council-approved election with two-thirds voter approval to change the tax structure itself.
- Run your total monthly cost, not just principal and interest. On Mare Island that CFD line item sits alongside standard property tax and is collected the same way, but it isn't capped by Proposition 13 the way your base property tax is.
- Weigh the ferry commute and housing stock against the tax the way the market already does. The data says buyers are paying more here, not less, so decide if the amenity is worth it to you specifically rather than assuming the price already accounts for it.
A Short FAQ
Does the Mare Island CFD show up on a standard title or disclosure report? Yes. It's collected on the property tax bill and disclosed as part of the standard transaction paperwork, but the dollar amount for your specific parcel won't be obvious from a listing sheet alone. Ask for the Rate and Method of Apportionment document directly.
Will the tax ever end? Under the city's own documents, the Services Special Tax on the newer CFD continues indefinitely. Ending it or restructuring it would require a City Council vote to put it to an election, with two-thirds of registered voters in the district needing to approve any change.
Is Mare Island still worth the premium? That depends on what you value in a commute and a home. The ferry access, walkable dining and coffee options, and newer construction are real and priced in. The tax situation is also real and unresolved. Go in knowing both halves of that equation rather than just the one on the listing photos.
