The Two Extra Weeks Every Tustin Legacy Sale Takes, and What Fills Them

"You think anyone's going to want to buy your home right now? No, it's economic damage."

Orange County Assessor Claude Parrish said that to Voice of OC in December 2023, a few weeks after the north hangar at the former Marine Corps Air Station Tustin collapsed in a fire that sent asbestos-laced ash drifting over Columbus Square, Greenwood, and the rest of Tustin Legacy. His office had just mailed 23,000 reassessment notices to homeowners near the wreckage. His read at the time was blunt: nobody would want to buy under that smoke plume for years.

Three years later, the closings tell a different story, but not the one you'd expect. Homes in Tustin Legacy sold for a median $1.4 million over the three months ending May 2026, up 6.5 percent from the same stretch a year earlier, with 23 homes changing hands that May compared to 21 the year before. Parrish's fear didn't show up in price. It showed up somewhere quieter: those same homes are now averaging 43 days on market, up from 30 days a year ago. Thirteen extra days, roughly two full weeks, that didn't exist before the fire.

That gap is not buyers losing interest. It's buyers, agents, and title companies doing paperwork that used to move faster, because Tustin Legacy sits on land with a documented environmental history and a disclosure obligation that most people don't discover until an escrow officer flags it.

The Paperwork the Land Actually Requires

Tustin Legacy is built on roughly 1,600 acres that were once Marine Corps Air Station Tustin, closed in 1999 after decades of helicopter and blimp operations. The Navy has been working through a formal cleanup process on the site ever since, and California law has a specific answer for what that means at closing.

Civil Code Section 1102.15 requires a seller with actual knowledge of any former federal or state ordnance location within one mile of the property to give written notice before transfer of title. The statute defines "former ordnance locations" as areas identified by a government agency as once used for military training, and former MCAS Tustin qualifies. In practice, sellers and their agents document this through the California Association of Realtors' Seller Property Questionnaire, alongside the standard Transfer Disclosure Statement. It's a form, not a warning label, but it's a form that has to get filled out correctly, and for a parcel this large, that's rarely a five-minute exercise.

None of this is new to the site. Voice of OC confirmed that language about the land remaining in remediation has appeared in Tustin Legacy buyer disclosures as early as 2008, years before the hangar fire made headlines. The fire didn't create the disclosure obligation. It just made buyers start asking to see it.

What the Navy Has Actually Found, and Where It Stands

The underlying issue is groundwater, not soil people are walking on. The city of Tustin's own remediation page states plainly that the shallow groundwater at Tustin Legacy isn't used for drinking water, and that drinking water for the community comes from the Irvine Ranch Water District and the Tustin Water Department, both sourced outside the base footprint. The contamination in question, primarily fuel and solvent byproducts along with PFAS from firefighting foam, sits in a groundwater layer that isn't tapped for household use.

That doesn't mean the cleanup is finished. Here's how the last five years have actually unfolded:

That last date is a month away. The review itself is a routine compliance step, required every five years under CERCLA Section 121(c) to confirm that existing cleanup remedies still protect human health and the environment. It is not a new discovery process. But anyone closing on a Tustin Legacy home this fall is doing so while that report is actively being finalized, which is exactly the kind of detail we raise with buyers at the start rather than leaving them to stumble onto it later.

The Letter Three HOAs Say They Never Got

Here's where the paper trail gets messier, and where a careful buyer earns their two weeks. When the Navy sent its 2021 warning letters to Columbus Square, Greenwood, and Anton Legacy, none of the HOA managers Voice of OC interviewed could confirm their association had actually received or distributed it. In Greenwood's case, the letter had been addressed to a staffer who'd left the company two years earlier, and the Navy appears to have kept emailing an address that hadn't been active since 2019.

That's not evidence of a cover-up. It's evidence of exactly the kind of institutional friction that shows up whenever a federal agency, a homeowners association, and a title company all touch the same disclosure and none of them owns the follow-through. The Navy holds twice-yearly Restoration Advisory Board meetings at the Tustin Senior Center specifically to keep residents current, and those meetings are advertised through the Navy's own site and in regional papers, yet attendance has reportedly been thin.

For a buyer or seller, the lesson isn't that the information is hidden. It's that the information sits in three different places, the HOA office, the Navy's public notices, and the historical disclosure paperwork, and none of those three are required to hand it to you automatically.

What to Ask For Before You Write or Accept an Offer

1. The completed Seller Property Questionnaire, specifically the section addressing former ordnance locations and environmental hazards, not just the standard TDS.
2. Direct confirmation from HOA management of any Navy correspondence on file, rather than assuming it was forwarded to residents when it arrived.
3. Written confirmation of the water source for the property, since Tustin Legacy homes draw drinking water from Irvine Ranch Water District or the Tustin Water Department, not from onsite groundwater.
4. The Fifth CERCLA Five-Year Review report once the Navy issues it, expected around October 2026, for anyone closing in the months immediately after.
5. The property's location relative to Operable Units 1A, 1B, 3, and 4B, which your agent or title company can request from the Navy's BRAC Program Management Office site for the former base.

None of these require a lawyer. They require someone who knows to ask, and on a parcel with this much documented history, asking early is the habit that keeps the two extra weeks from stretching longer.

Frequently Asked Questions

Does the ordnance disclosure apply to every home in Tustin Legacy? Civil Code 1102.15 applies to any residential property within one mile of a known former ordnance location, which covers the full Tustin Legacy footprint given its position on the former base.

Is the groundwater contamination a drinking water risk? According to the city of Tustin, no. Drinking water is supplied by Irvine Ranch Water District and the Tustin Water Department from sources outside Tustin Legacy, and the affected shallow groundwater isn't used for irrigation or household water.

Does the upcoming Five-Year Review mean new contamination was found? No. CERCLA requires this review every five years regardless of new findings, to confirm existing remedies are still working. It's a scheduled compliance check, not a new investigation triggered by a fresh problem.

What if my HOA says it never received anything from the Navy? That's been true for all three HOAs the Navy contacted in 2021. It doesn't mean nothing was ever disclosed. Ask for the property's historical TDS and SPQ records directly, since remediation language has been part of Tustin Legacy disclosures since at least 2008.

The fear in 2023 was that nobody would want to buy here. The 2026 numbers say buyers showed up anyway, they just needed two more weeks to get comfortable with the paperwork. Whether you're the one selling or the one asking for that paperwork, knowing what's actually on file, and where it lives, is what turns those two weeks from a delay into due diligence.
