California Supreme Court Unanimously Reins in Coastal Commission’s Overreach in Major Property Rights Victory

In a unanimous decision hailed as one of the most significant checks on the California Coastal Commission’s (CCC) power in nearly 40 years, the California Supreme Court ruled Wednesday that the agency unlawfully overrode a county-approved building permit for a homebuilder in San Luis Obispo County.

The ruling in Shear Development Co., LLC v. California Coastal Commission affirms that the unelected CCC cannot simply second-guess local governments’ interpretations of their own Local Coastal Programs or invent new jurisdictional claims based on non-binding illustrations in county plans.

Pacific Legal Foundation (PLF), which represented Shear Development pro bono, celebrated the victory as a win for every coastal property owner. “Today’s decision is a win for every property owner along California’s coast,” said PLF attorney Jeremy Talcott. “The Coastal Commission cannot simply decide to reinterpret legislation based on its own whims. Its authority has limits, and today the court enforced them unanimously.”

The case stems from Shear Development’s purchase of eight residential lots in Los Osos in 2003. The company built infrastructure for all eight homes with San Luis Obispo County approval and planned construction in two phases. In 2017, the county approved the phase-two permits under its certified Local Coastal Program. But the CCC appealed the county’s decision to itself, claiming jurisdiction based on a buried illustration in a county area plan—rather than the official maps required by the Local Coastal Program.

Represented by PLF, Shear sued to hold the Commission accountable to the law. The Supreme Court agreed, reversing the CCC’s overreach and reinforcing the limits on its appellate authority over local permitting decisions.

“This decision corrects the Commission’s overreach,” Talcott added. “For years, the Commission has usurped the power given by the state legislature to local coastal communities to approve homebuilding permits.” 

San Luis Obispo County, the League of California Cities, Californians for Homeownership, and the California Association of Realtors filed amicus briefs supporting Shear and urging the court to curb the CCC’s expansive reach. The state agency, comprised of political appointees, controls over 1.5 million acres of coastal land.

The ruling marks a rare judicial rebuke of the CCC, an agency created in the 1970s that has long been criticized for wielding near-unchecked power over development along California’s 840-mile coastline. As the California Globe has repeatedly documented, the Commission has obstructed critical projects ranging from desalination plants to SpaceX rocket launches and even wildfire rebuilding efforts in Pacific Palisades and Malibu.

California Globe contributor Edward Ring highlighted the agency’s flawed premise and its preference for “managed retreat” over practical property rights. Our coverage of the CCC’s denial of SpaceX launches and its recommendations against the Huntington Beach desalination plant underscored how the Commission’s decisions often prioritize ideology over housing, infrastructure, and economic growth.

PLF has a storied history of challenging CCC abuses, most famously securing a landmark U.S. Supreme Court victory in Nollan v. California Coastal Commission (1987), which established that the agency cannot condition permits on the surrender of private property without just compensation. 

Today’s unanimous state high court decision builds on that legacy, delivering another blow to bureaucratic overreach. 

For Shear Development and countless other coastal property owners, the ruling offers hope that local control and property rights may finally prevail over unelected state agencies. In a state grappling with a severe housing shortage, Wednesday’s decision could pave the way for more sensible permitting and less arbitrary interference from Sacramento’s coastal overlords.
