California is suing Half Moon Bay, a San Mateo County city, for failing to get its state-mandated housing plan approved. The lawsuit filed Thursday, July 16, in California Superior Court makes Half Moon Bay the first Peninsula city to face legal action under the state's escalating housing enforcement campaign.
Half Moon Bay is one of five cities targeted in what the governor's office called "No More Excuses." The others are Calexico, Costa Mesa, Ridgecrest, and Turlock. Attorney General Rob Bonta and Department of Housing and Community Development Director Gustavo Velasquez announced the action, Bloomberg Law reported Friday, July 17.
The lawsuits seek a court order compelling each city to adopt a compliant housing element and finish required rezoning within 120 days, according to the Los Angeles Times.
Half Moon Bay had received a prior final warning as one of 15 cities statewide that failed to meet the 2023-2031 housing element cycle, the San Mateo Daily Journal reported.
What non-compliance costs
The financial consequences are concrete. A judge ordered Huntington Beach to pay $160,000 in penalties with fines escalating to $50,000 per month until it complied, according to the Los Angeles Times. Huntington Beach's council voted 5-2 on Thursday, June 16, to finally approve its overdue housing plan.
"At this point, I believe I need to be a 'yes' vote for the sake of our taxpayers," Huntington Beach Councilmember Don Kennedy said at that June 16 meeting. "I believe that the path of non-compliance will lead to much more financial pain than I'm willing to put on the citizens."
Beyond fines, cities that continue to miss benchmarks can lose the ability to issue nonresidential building permits. The state can also invoke a "Builder's Remedy" provision that allows housing projects to bypass local planning commissions entirely.
Why it matters in San Mateo
San Mateo is not in the state's crosshairs. The city adopted its 2023-2031 Housing Element in January 2023 and holds a certified plan. But the city still must accommodate 7,015 new units by 2031: 1,177 very low income, 1,023 low income, 1,175 moderate income, and 3,040 above moderate income, according to city planning documents.
To meet that mandate, the City Council has been advancing four new high-density zoning districts that would allow buildings up to eight stories and 100 feet for mixed-use projects. A January 2026 city white paper confirmed public hearings were planned for the first half of 2026, and the Community Development Department lists the ordinance amendments as an active effort.
Senate Bill 79, which took effect Wednesday, July 1, adds another layer of state pressure on San Mateo County cities. The law requires all county jurisdictions to approve qualified transit-oriented housing projects near major transit stops.
What's next
San Mateo's City Council holds both a special meeting and a regular meeting on Monday, July 20, at City Hall, 330 W. 20th Ave. The council includes Mayor Adam Loraine, Deputy Mayor Nicole Fernandez, and members Danielle Cwirko-Godycki, Lisa Diaz Nash, and Robert Newsom Jr. Meeting agendas for July 20 were not publicly available at publication time.
San Mateo city officials did not respond to requests for comment.
