Protecting Property and Development Rights in Marin County

Marin County’s environmental and coastal regulations can create major challenges for property owners and developers. When government action interferes with lawful use or development, experienced legal representation can help protect your interests.

A land use denial in Marin County can halt a project that took years to plan. A Planning Commission vote, Board of Supervisors decision, or California Coastal Commission ruling can freeze development, block permits, or eliminate project viability altogether — particularly within Marin’s environmentally sensitive and hillside regions.

California law allows property owners and developers to challenge unlawful land use decisions through writ proceedings in superior court. Kassouni Law evaluates whether the agency followed the law, applied correct standards, and relied on valid evidence before denying approval in Marin County.

Writ of Mandate & Marin County Land Use Litigation

Administrative Mandamus (CCP § 1094.5) applies when a public agency conducts a formal hearing and issues a final decision affecting a vested right. The court reviews whether the agency proceeded legally, whether the decision is supported by substantial evidence, and whether the agency abused its discretion.

Traditional Mandamus (CCP § 1085) applies when no formal evidentiary hearing occurred — challenging failures to perform a required duty, actions outside legal authority, or violations of mandatory procedures.

Both writ types form the backbone of land use litigation in Marin County Superior Court, with appeals proceeding to the First Appellate District.

CEQA, Coastal Act & The Administrative Record

Courts apply substantial evidence review for factual findings, abuse of discretion for agency decisions, and de novo review for legal questions. Every land use appeal depends on the administrative record: hearings, staff reports, environmental documents, and public comments. The court cannot consider new evidence, so building the record early is critical.

For properties within Marin’s coastal zone, the California Coastal Act and Local Coastal Program add additional layers of review. Legal challenges may involve both CEQA compliance and Coastal Development Permit requirements, as well as hillside and ridgeline protection ordinances.

Common legal errors include failure to follow county zoning ordinances, misinterpretation of environmental standards, lack of substantial evidence supporting a denial, procedural due process violations, and inconsistent application of development conditions.

The Housing Accountability Act & Marin’s Land Use Context

California Government Code § 65589.5 (Housing Accountability Act) limits local governments’ ability to deny qualifying housing projects without proper justification, requiring agencies to approve compliant housing projects, provide written findings, and support decisions with substantial evidence — an increasingly important tool in Marin County’s efforts to address housing supply while navigating stringent environmental and coastal regulations.
