HCD to Costa Mesa: A Federal Win Doesn't Clear a State-Law Denial

You run a sober living home in Costa Mesa — or you're trying to keep one open. It's operated for years without a health-or-safety complaint. Then the city tells you the house doesn't fit its definition of a "single housekeeping unit," makes you file a reasonable accommodation request to keep going, and denies it. And when you push back, the city points to a court win and says it's in the clear.

Here's the thing: California's housing department looked at exactly that situation and told Costa Mesa its position was wrong — a federal court win doesn't answer the state-law question, and the denial has to be reversed.

The home HCD is talking about

The letter concerns 115 E. Wilson Street, five single-family homes operated as recovery residences by The Ohio House, LLC since 2012. On May 2, 2025, Ohio House and five of its residents applied for a reasonable accommodation to keep operating. The city denied it on July 2, 2025, and its Planning Commission upheld the denial on September 22, 2025. The denial was appealed. HCD's read of the track record is blunt:

"In its 14 years of operation, Ohio House has not caused problems that disrupt or fundamentally alter the community."

HCD noted the city didn't claim the denial rested on any real threat to neighbors' health or safety.

Verified against HCD's Letter of Technical Assistance to the City of Costa Mesa — Request for Reasonable Accommodation, 115 E. Wilson Street (June 8, 2026).

What HCD found

HCD's position is that Costa Mesa should never have forced the home to ask permission — then denied the request under an unlawful process. HCD flagged the city's own findings — including whether an accommodation would "fundamentally alter the character of the neighborhood" — and wrote: "These provisions are subjective, potentially prejudicial, and can serve as constraints, violating Housing Element Law."

It also called out standards that reach beyond the individual home: an "adverse external impacts on properties in the vicinity" clause, and a cost test weighing the burden of granting "and other requests like it." Under state law, HCD said, each request "must be considered and evaluated on a fact-specific, case-by-case basis" — not judged by what might happen if everyone asked. And even under the city's own rules, HCD found "the City failed to meet its burden of justifying its denial of the application."

The federal-win trap

Costa Mesa did win at the Ninth Circuit in 2025 in The Ohio House, LLC v. City of Costa Mesa (135 F.4th 645). But HCD's position is that the win doesn't reach the state-law claims — the decision, HCD wrote, came "without fully analyzing the relevant state laws."

HCD points to a later federal district court decision, Insight Psychology and Addiction, Inc. v. City of Costa Mesa (801 F.Supp.3d 942). That court read the appellate decision as having "ruled that the terms of the City's reasonable accommodation ordinance complied with federal law but did not consider or rule on whether they complied with state housing laws." HCD also flagged a June 3, 2026 legal alert it issued with the Civil Rights Department and the Attorney General's Office on why cities should still follow state housing-law guidance after the Ohio House decision.

The takeaway: a federal fair-housing outcome is not a clean bill of health under California's separate framework — the Anti-Discrimination in Land Use Law (Gov. Code § 65008), AFFH Law (Gov. Code § 8899.50), and Housing Element Law (Gov. Code § 65583).

Why this matters beyond one house

HCD reads Costa Mesa's regime as a template with reach. Before the city's group-home ordinances, it estimated 94 sober living homes in its residential zones; the city's website now counts 16 approved group homes, with 83 closed. HCD noted that at least 11 other cities in Orange County have looked to Costa Mesa's rules as a model. If you run a home that operates as a household and provides no state-licensed services, HCD's framing is that a long, quiet track record cuts in your favor — and subjective findings about neighborhood character don't.

One caveat that matters

A Letter of Technical Assistance is HCD's interpretation of state law — not a court ruling. It flags where HCD believes a city is offside and the enforcement risk it's running; courts remain the final word, and the Ohio House history shows federal and state questions can land differently. If you're facing an accommodation denial, confirm how it's applied to your property with your jurisdiction and get your own counsel before relying on any of this. HCD's stated position here is that "The City Council must grant the appeal and approve the reasonable accommodation application."
