A listener once wrote in to a Bay Area public radio show wondering if it was even possible to buy a house in the East Bay next to real, undeveloped land. Someone pointed her toward Concord, where more than 5,000 acres of rolling hills sit behind a local high school, camouflaged bunkers included. That land is not empty. It's the former Concord Naval Weapons Station, and this spring the city cleared the last major hurdle standing between that acreage and a new town.
If you're weighing a purchase in Concord this year, you've probably already seen the number attached to that story: more than 12,000 homes. What you may not have seen is the number that actually matters for a 2026 transaction, and it isn't 12,000. It's the gap between "approved" and "occupied," and it's wider than most headlines let on.
What the City Actually Signed Off On
On May 26, 2026, the Concord City Council voted unanimously to approve a financial agreement with the U.S. Navy, clearing the way for master developer Brookfield Properties to redevelop roughly 2,400 acres of the former base. Brookfield will pay the Navy $628 million over nearly 30 years for the land, and the plan calls for 12,272 homes, a quarter of them set aside as affordable, along with 6 million square feet of commercial space and more than 800 acres of parks, according to The Real Deal.
This is not Brookfield's first attempt at a deal like this in Concord, and it isn't the city's first attempt at a developer, either. The council rejected a term sheet with a previous developer, Concord First Partners, in 2023 before turning to Brookfield. The May agreement is the piece that had eluded the city for two decades: a settled price with the Navy itself, per Local News Matters.
The Seven-Year Head Start Before Anything Gets Built
Here is the part that gets lost in a headline built around a single big number. Approval is not the same as groundbreaking, and groundbreaking is not the same as move-in day.
| Milestone | Expected Timing |
|---|---|
| Navy financial agreement approved | May 26, 2026 |
| Specific Plan presented to City Council | Summer 2029 |
| Roads, water, power, and sewer infrastructure begins | 2030 |
| First buildings constructed | 2033 |
| Full five-phase buildout | Roughly 30 years, unfolding into the 2050s |
Those aren't estimates I'm putting together. City officials told CBS San Francisco that infrastructure work could begin around 2030, with the first buildings going up in 2033, and that the specific plan itself won't reach the council until roughly summer 2029, per CBS News and Local News Matters. The Real Deal reports the entire project is expected to unfold in five phases over approximately three decades.
The city's own base reuse director, Guy Bjerke, is the one urging caution here, not a skeptic on the sidelines. He called the agreement the best deal the city was going to get from the Navy, then immediately tempered it, cautioning residents to "not overestimate how much money the city is going to see as part of this project."
That's a project official telling residents not to get ahead of themselves on revenue projections. The same advice applies to anyone pricing a home purchase or listing around what this land will eventually become.
The Transit-Oriented Plan With an Asterisk
The first phase of construction is planned for the area next to North Concord BART, and the pitch has always leaned on that proximity: dense, walkable, transit-connected housing replacing a fenced-off military site.
Here's the friction. BART's own long-range planning includes a scenario in which the North Concord station closes. City planner Andrea Hoffmeister acknowledged the tension directly to CBS San Francisco, describing the plan as "transit-oriented development, without transit — Maybe?" She added that locking in commercial and retail plans a decade out is difficult precisely because so much can shift before the district is actually built.
If you're evaluating a property specifically because of its future proximity to a redeveloped, transit-anchored district, that's a genuinely open variable, not a settled fact, and it's worth confirming BART's current service plans rather than assuming the station's presence is guaranteed for the life of a mortgage.
What This Has to Do With Your Offer This Year
None of the above changes what's happening in Concord's resale market right now, because none of it is happening yet. As of March 2026, homes in Concord were spending an average of 36 days on the market, inventory sat at well under one month of supply, and just over half of listings closed above their original asking price. Sales volume was up too: 296 homes sold in May 2026, compared with 287 the year before.
Price trackers disagree with each other more than usual right now. One widely used home value index showed Concord's typical value down roughly 8 percent year over year through June 2026, while median sale price figures over a trailing three-month window came in essentially flat. That disagreement says more about how each source calculates its number than about what's happening on the ground. With supply this tight, the more reliable signal is pace, not the price index of the week.
None of that pace has anything to do with buildings that won't exist until 2033 at the earliest. A seller citing the naval station announcement as justification for a premium asking price this year is borrowing against a timeline that hasn't started. A buyer hesitating on a purchase because they expect an imminent flood of new inventory is making the same mistake in the other direction.
Before you let this project factor into an offer, three questions are worth asking:
- Is the property actually inside the reuse footprint, adjacent to it, or simply in the same zip code? Those are very different things for both disclosure purposes and long-term planning.
- Does the value you're placing on the location depend on North Concord BART remaining open in its current form?
- Are you being asked to pay today for appreciation that depends on infrastructure that hasn't broken ground?
The Land Itself Has a To-Do List First
Before any of the 12,272 homes gets built, the Navy still has cleanup work to finish. Bjerke described the site to ABC7 as "a complicated project with endangered species, remediation and contamination cleanup," which is standard language for a former munitions storage facility but a real, sequenced requirement rather than a formality, per ABC7 News.
Roughly half of the original base, about 2,500 acres, has already been transferred to the East Bay Regional Park District and will eventually become Thurgood Marshall Regional Park, complete with historic tours of the old ammunition bunkers. It isn't open to the public yet. That half of the story got there through years of advocacy from residents like Kathy Gleason, whose backyard abuts the old base and who helped organize opposition to development in the years right after the base closed in 2005, according to KQED's reporting. The parkland is a done deal. The housing is not, at least not yet.
Frequently Asked Questions
Will 12,000 new homes make my Concord home worth less? Not on any timeline relevant to a purchase or sale this year. The soonest reported date for occupied housing is 2033, and that's only the first of five planned phases stretching across roughly three decades.
When does construction actually start? Infrastructure work such as roads, water, and sewer is projected to begin around 2030, after the Specific Plan is presented to the City Council in summer 2029. Vertical construction on the first buildings is projected for 2033.
Should I be concerned about buying near North Concord BART because of this project? It's worth confirming BART's current service plans directly rather than assuming permanence. City planners have publicly acknowledged that closing the North Concord station is one of the scenarios in BART's own long-range planning, which complicates the transit-oriented framing attached to the project's first phase.
If you're trying to figure out what a specific Concord address is actually worth this year, separate from a headline about 2033, that's the kind of read I do for a living. I've spent enough time on construction sites to know the difference between an approved plan and a poured foundation, and I'll walk you through exactly where your property sits relative to this project, what it means for your timeline, and what it doesn't.
