Diana Varat

Of Counsel | Los Angeles


Drawing from her background in urban planning, Diana Varat has advised dozens of public agencies in California on complex land use and housing matters. Diana has extensive experience preparing and reviewing general plan updates, specific plans, and zoning code amendments. Since the State’s passage of the 2017 Housing Package, Diana has focused her practice on compliance with California’s housing-related land use laws, including Housing Element Law, the Housing Accountability Act, the Housing Crisis Act of 2019 (SB 330), Density Bonus Law, No Net Loss, and streamlined housing approvals (SB 35). Diana frequently presents legislative updates to City staff, Planning Commissions, and City Councils to educate local officials on how best to comply with State law and simultaneously create vibrant communities. Diana has drafted numerous ordinances to implement housing element law on topics including: accessory dwelling units, inclusionary housing, density bonuses, emergency shelters, transitional and supportive housing, and reasonable accommodations procedures.

As an expert in ethics laws, Diana helps public officials analyze potential conflicts of interest under the Political Reform Act and Government Code Section 1090. With her guidance, public officials have sought and received favorable advice from the Fair Political Practices Commission, allowing them to participate in agency decisions without violating California’s conflict of interest laws.   

In addition to her legal practice, Diana has served as a Lecturer in the Department of Urban Studies & Planning at California State University, Northridge and the Department of Urban Planning at the UCLA Luskin School of Public Affairs. She has taught courses on the legal foundations of planning, urbanization in the U.S., and the development of Los Angeles. In 2017, she advised a group of UCLA students in preparing their final project for the Masters degree, analyzing the community impacts of the LA River revitalization process along the Lower LA River.

Diana previously served as the Assistant City Attorney for the cities of Agoura Hills and Manhattan Beach.  In her role as Of Counsel to the firm, Diana now focuses on implementing State housing laws, conflicts of interest questions, and complex land use and planning projects for numerous cities, including Sunnyvale, La Habra, Beverly Hills, Rancho Cucamonga, Temecula, Davis, Redondo Beach, and Agoura Hills.

Professional Experience

Before embarking on her law degree, Diana worked for the City Planning Department for the City of Dresden, Germany. Diana also previously served as the Project Associate for the Woodrow Wilson International Center for Scholars’ Comparative Urban Studies Project in Washington, D.C.
