Todd Koerner had been renting a spare bedroom in his Manhattan Avenue home on Airbnb since 2012. When the city cited him $2,500 for operating an illegal short-term rental, he didn't pay it. He fought it, with land use attorney Frank Angel representing him, and the case ended up doing something a single $2,500 fine rarely does: it unraveled a decade of Hermosa Beach rental policy.
If you own coastal-zone property in Hermosa Beach, or you're evaluating one as a buyer or investor, you've probably heard the headline version of what happened next. Short-term rentals are legal again. What gets left out of that sentence is the part that actually affects a transaction: the city didn't just drop enforcement, it opened a portal, started counting back to May 2022, and gave owners until August 1 to settle up before penalties applied. That deadline passed eight days ago.
The ruling, in the terms that matter
Hermosa Beach banned short-term rentals citywide in 2016. So did Manhattan Beach, the same year. Both bans eventually ran into the same legal problem: California's Coastal Act requires cities to get California Coastal Commission approval before restricting land use inside the coastal zone, and neither city had one for its ban.
Angel had already proven this once. In 2019 he sued Manhattan Beach on behalf of client Darby Keen over a coastal-zone rental, won in the lower courts, and watched the California Supreme Court decline to hear Manhattan's appeal in 2022. Manhattan Beach dropped its enforcement, now runs short-term rentals in the coastal zone, and collects more than $1 million a year in transient occupancy tax from them, according to city reporting cited by Easy Reader News.
Koerner's case followed the same path through the same court. Superior Court Judge James C. Chalfant, the judge who had ruled against Manhattan Beach years earlier, issued a preliminary injunction protecting Koerner in July 2025, then a final ruling in March 2026 that dismissed his citation outright and blocked the city from enforcing its ban anywhere in the coastal zone until the Coastal Commission signs off. On May 12, 2026, the Hermosa Beach City Council voted 4-1 in closed session not to appeal. The coastal zone covers roughly 43 percent of the city's land area, and the city's Local Coastal Program, the document that would let it write new rules with Commission approval, has never been certified.
What "legal" actually triggered
Here's where the story stops looking like Manhattan Beach's and starts looking like something else. On June 4, 2026, the city launched a property registration and tax portal, built with a vendor called Deckard Technologies, and announced that every short-term rental operator in the city now has to register, obtain a business license, and pay transient occupancy tax back to May 2022. Owners who registered and paid what they owed by August 1, 2026 had interest and penalties waived. Owners who didn't are now exposed to both.
City staff have floated an estimate of roughly $5 million in retroactive tax revenue sitting in unlicensed rentals, a number city spokesperson Ryan Walker acknowledged is uncertain, telling Easy Reader News the lookback period "is quite unique." Mayor Mike Detoy framed the move plainly: "the courts have forced our hand on short-term rentals."
The city is trying to collect four years of tax on an activity it spent those same four years insisting was illegal.
That's not a rhetorical flourish. It's the actual legal question Angel raised publicly the same week the city's June 9 council meeting took up the issue, and it's still unresolved.
The retroactive bill has its own lawsuit brewing
Hermosa's transient occupancy tax ordinance was written by voters, not the council. It passed as Measure H in November 2015, and it applies specifically to "permitted" short-term rentals. In March 2026, the council quietly deleted the word "permitted" from the ordinance's text, a change meant to let the city collect tax from rentals that were never licensed under the old ban.
Angel argues the council doesn't have that authority. A voter initiative can only be amended by voters, he contends, which means the retroactive bill for years of unlicensed activity may be resting on a legal foundation the council can't actually build on its own. Councilmember Ray Jackson raised concerns about the word "permitted" appearing in the city's own press release. Councilmember Michael Keegan suggested the city hold off and see how voluntary collection goes rather than force the issue, pointing to Manhattan Beach's quieter, hands-off approach after its own ruling.
None of this changes what's true today: the coastal zone ban can't be enforced, and the city is actively billing owners for past activity. It does mean the bill itself, and possibly the registration requirement behind it, could still be challenged.
Where the rules stand right now
| Zone | Short-term rental status | What's required |
|---|---|---|
| Coastal zone (west of Ardmore/Valley) | Unenforceable ban, no citations | Register, license, pay TOT back to May 2022 |
| Residential neighborhoods east of the coastal zone | Still illegal under the 2016 ordinance | None permitted |
| Commercial zones (downtown, PCH corridor, Aviation Blvd. pilot area) | Legal for 212 eligible nonconforming residences | City permit, $1,500 annually |
What this means at the table, not the headline
For a seller with a coastal-zone property that has hosted short stays since 2022, silence on the registration question is a liability, not a shortcut. A buyer's agent who knows to ask will ask, and an unregistered history is the kind of thing that surfaces in escrow rather than before it.
A few things worth sorting out before you're at the negotiating table, whichever side you're on:
- If you're selling a property with any short-term rental history, confirm its registration and TOT status on the city's portal before you list. An open liability tied to the address is worth resolving, or at minimum disclosing, ahead of a buyer's diligence period.
- If you're buying in the coastal zone with rental income in mind, ask directly whether the property has been advertised on Airbnb, Vrbo, or similar platforms since May 2022, and whether that history has been registered. Don't assume the seller's disclosure covers it unprompted.
- If you're underwriting projected rental income, treat the current legal status as recent and still contested, not settled. Manhattan Beach took from 2019 to 2022 to reach a final, unappealed resolution. Hermosa Beach is just under three months past its own council vote not to appeal, with the tax mechanism behind it already facing a challenge to its legal footing.
- If you already operate a short-term rental in the coastal zone, missing the August 1 deadline doesn't mean missing the opportunity to register. It means the interest and penalty waiver is gone. Registering later is still better than not registering.
Why Hermosa's timeline may not compress the way Manhattan's did
The city isn't approaching this from a position of comfort. Staff presented a $3.2 million structural deficit and an unfunded capital improvement backlog estimated between $90 million and $220 million at the May 12 budget session, with short-term rental tax revenue listed as one strategy under review. That's real motivation to keep pushing collection forward, and real motivation to eventually build a permanent licensing structure rather than leave the coastal zone in its current unregulated, untaxed-until-recently state.
But a permanent structure still requires Coastal Commission review, the same requirement that took down the original ban. An uncertified Local Coastal Program doesn't resolve itself quickly. The most likely near-term outcome is more of what's happening now: registration pressure, a contested tax mechanism, and a council that hasn't agreed internally on how hard to push.
Does this affect short-term rentals outside the coastal zone? No. The 2016 citywide ban is still enforceable everywhere except the coastal zone and the small pool of pre-existing commercial-zone properties in the pilot program.
What if a rental was only advertised occasionally, not run as a full business? Hermosa Beach's municipal code defines a short-term vacation rental as the rental of a dwelling, unit, or even a single room for under 30 days. Koerner's case started with one spare bedroom. Scale doesn't appear to be the threshold that matters.
Is the retroactive tax bill final? Not clearly. Attorney Frank Angel has publicly questioned whether the council had the authority to amend a voter-approved ordinance to reach it, and that question hadn't been resolved as of this writing.
If you're weighing a coastal-zone purchase, a sale with rental history attached, or how a short-term rental fits into a longer-term South Bay portfolio, this is exactly the kind of local detail that changes the math on paper versus the math at closing.
