Zillow lost a ruling this week. Here is what it actually means if you are buying or selling in the South Bay.

First, the plain version

If you are buying, you are not seeing everything

You can say that plainly without taking anyone’s side, because there are three separate gaps and none of them is in dispute.

Some sellers instruct that their home never reach the MLS at all. Some brokerages market a home on their own site before it reaches the MLS. And some listings are excluded from Zillow and Trulia under the standards above even though they exist elsewhere.

The practical version: a portal is a marketing channel, not a complete market. If you are searching seriously, ask an agent to send you the full MLS feed, and then ask specifically about the inventory that never appears on a portal at all.

What this actually means in the South Bay, which is the part nobody local is telling you

Every South Bay listing runs through CRMLS. The South Bay Association of Realtors in Torrance and the Palos Verdes Peninsula Association both participate in it. And CRMLS made a decision in April 2025 that changes this conversation here.

When the National Association of Realtors created a new Delayed Marketing option, letting a seller hold a listing back from public syndication for a window set by the local MLS, CRMLS declined to adopt it. Its own announcement says so directly. There is no delayed marketing exempt listing in this market.

So a South Bay seller has three real options, not four.

Coming Soon is the one most sellers here are actually looking for when they ask about staying off the public sites at first. Up to 21 days of marketing with no days-on-market clock running, at the cost of no showings during it. Registered is genuinely private and costs you the entire buyer pool outside one brokerage.

Both require a signed seller certification acknowledging what you are giving up. Read it rather than initialing it.

What the judge actually decided

Judge John Tharp denied Zillow’s request for a preliminary injunction, dissolved the temporary order that had been keeping Zillow’s listing feed switched on in the Chicago market, and sent Zillow’s claims against the MLS into private arbitration. Its claims against Compass are paused until that finishes.

The court found Zillow had not shown the two had agreed to cut off its access. In the opinion’s words, Zillow’s circumstantial evidence did not sufficiently distinguish an agreement from the competing inference of independent conduct.

Here is what the court did not do, and this is the part being misreported. It made no finding that Zillow’s listing policies are anticompetitive. It did not rule on who should control a listing. Compass has said publicly that the decision affirms that choice belongs to the homeowner. That is a statement by a party to the case, not something the judge held. Zillow has said this was not a final ruling on its case, which is also true, and also a statement by a party.

Nothing has been decided about whether any of this is legal. A procedural round was won and the fight moved rooms.

Why this should matter to you even though it sounds like corporate news

The thing being fought over is not really software. It is who decides what you get to see.

For most of the past thirty years there was one answer. A home for sale went into the MLS, the MLS fed everyone, and every agent and every portal worked from the same list. That arrangement is what made it possible for an ordinary buyer to know what was actually available without hiring the right insider.

What is being tested now is whether that holds. If a brokerage large enough can keep inventory on its own platform first, and a portal large enough can refuse to show homes that were marketed elsewhere, then what you see depends on which company you happened to start with. Not on what is for sale.

Nobody has to be a villain for that to end badly for a buyer. Two companies acting in their own interest is enough.

The practical consequence today is smaller and more manageable than the headlines suggest. But the direction is the thing to watch, and it is the reason we are going to keep writing about it as it moves.

The scoreboard, because this is round two of a longer fight

Neither company has won anything that decides the question. What has happened is that each one asked a judge for emergency relief, and each one was told no. It is one to one, and both losses were the same kind of loss.

One to one, and neither point was scored on the merits. Both rulings say the same narrow thing in different directions: you have not met the high bar for a court to step in early and change the status quo while the case is still being argued. That is a long way from a judge deciding whether any of this is legal.

It matters that both losses were on preliminary injunctions rather than trials, because it means the underlying question, whether a portal may condition display on how a home was marketed, and whether a brokerage may hold inventory back from the market, is still entirely open. Two of the largest companies in American residential real estate have now each failed to get a court to settle it quickly.

The rule everyone is arguing about has already changed

Zillow rewrote its listing access standards on March 17, 2026, and the current version is looser than the one that started the fight.

The one-business-day timing requirement is gone. Listing in an MLS is no longer required, so long as the home is made broadly accessible to the public somewhere. What is still excluded is gated marketing, meaning a listing a buyer can only see by agreeing to work with the brokerage that holds it.

If you read that a listing gets three strikes before Zillow blocks it, that was the 2025 version and it is not the current rule. Under the rule as written now, a non-compliant listing simply is not shown on Zillow or Trulia, and that exclusion follows the listing for as long as it stays with the same agent or brokerage, including under a new listing agreement.

Does selling privately get you more money?

The two loudest studies are by the two companies suing each other, and they reach opposite conclusions. We are not going to pick one.

Zillow published in May 2026 that sellers who went off-MLS typically sold for about 1.3 percent less, roughly $4,230 per home, with the gap widest at lower price points and in communities of color. It is Zillow’s own data and its own valuation model, and Zillow is a party to litigation about exactly this question.

Compass published that homes starting as a private exclusive or coming soon sold for about 4.6 percent more, across roughly 70,000 of its own closed transactions. Compass discloses a real limitation in its own analysis: it counts only homes that sold, and excludes listings that were withdrawn or expired without selling. That exclusion matters, because the homes a strategy fails on are exactly the ones that drop out.

Outside the two litigants, the picture is genuinely mixed. Bright MLS found no financial advantage to pre-marketing off the MLS. An academic study of twenty years of Dallas-Fort Worth sales found pocket sales went for about 1.7 percent more, with a larger premium at the luxury end, though it covers one market and Compass cites it.

The honest summary is that nobody has settled this, and anyone who tells you the answer is obvious is selling you something. What is not in dispute is the mechanism: fewer buyers see the home. Whether that costs you money depends on how many of the right buyers you needed to reach.

What to actually do

Selling. Decide what you want privacy for. Testing a price without a public days-on-market record is a real reason, and Coming Soon does it. Avoiding the market entirely is a different decision with a real cost. Ask whether a private route will later block the listing from Zillow and Trulia, because that exclusion follows the brokerage.

Buying. Assume the portal is incomplete and ask directly what is not on it.

One more thing worth watching rather than acting on. Compass closed its acquisition of Anywhere Real Estate in January 2026, bringing Coldwell Banker, Sotheby’s International Realty, Corcoran and Century 21 under one roof, all of which have a South Bay presence. How private inventory rules apply across a company that size is the question underneath all of this, and it has not been answered yet.

One structural thing worth understanding about who you hire

Everything above is a fight between two companies that each have somewhere of their own to put a listing. A portal wants homes on its portal. A brokerage with a private network wants homes in its network first. Both of those are rational business positions and neither requires anybody to behave badly.

But it does mean that when a seller at one of those companies asks where their home should go first, the answer arrives with an extra consideration attached that has nothing to do with that particular house.

We have no platform of our own to feed. Chhabria Real Estate Company has been independently owned and operated since 2016. There is no private listing network here, no parent company with a portal, and no corporate policy about where inventory goes before it reaches the MLS. So the question of how to market your home is decided by what serves your sale, because there is no second interest in the room.

That is a structural fact rather than a claim about character. Plenty of excellent agents work at large firms and most of them will tell you the same thing we would about any given house. The difference is only that Chhabria Real Estate is never choosing between two answers.

The other half of it is narrower and more useful. The rules that actually govern this in the South Bay are CRMLS rules, and they are not the national rules. CRMLS did not adopt the delayed marketing option. Its cumulative days window changed from ninety days to thirty in November 2025. The Coming Soon window is twenty-one days and you get one. Knowing which of those apply to a house on a particular street in Hermosa or Palos Verdes is local work, and it does not scale from a national playbook.

We wrote the longer version of those rules up separately, at what CRMLS actually allows a South Bay seller to do.

This is not over, and it will move again

Eighteen months ago none of this existed. A portal set a rule, a brokerage sued, a court said no, the rule was rewritten, the brokerage walked away, the portal sued somebody else, and a second court said no again. That is four direction changes in six quarters.

What happens next is genuinely unknown. The live matter goes to private arbitration, which means the next development may not be public when it happens. Other proceedings and inquiries are open. None of them has reached a conclusion, which is exactly why we are not going to characterize them.

So treat any article about this, this one included, as a snapshot rather than an answer. Including the ones that sound certain. Especially the ones that sound certain.

We will keep this page current as things actually resolve. If you are weighing a decision on a specific property, the rule that matters is the one in force the week you list, not the one in force when this was written.
