The DAC team includes the Planning and Zoning Counter, Land Use Data Monitoring and Permit Processing. For information regarding any of the areas covered by the Development Assistance Center please call 949-724-6308. Planning and Development staff are available at the Planning and Zoning Counter of the Community Development Department, located in City Hall, to answer any of your questions, and to facilitate your development application.

The Development Assistance Center (DAC) is equipped to answer questions regarding planning and zoning regulations. The Planning and Zoning Counter is open Monday through Friday from 8 AM to 5 PM.


We review building permit applications ranging from new construction to minor additions or interior improvements for commercial and residential properties.


Discretionary case applications require additional review time. Conditional Use Permits may be required depending on the Planning Area and zone in which a proposed use will be located. Depending on the type of application, it may be reviewed by the Zoning Administrator or the Planning Commission. Public hearing items considered by the Zoning Administrator require up to 8 weeks to process, while public hearing items considered by the Planning Commission require up to 16 weeks to process. Subdivision matters will be processed within 50 days of acceptance of filing.
