In addition, RMA has identified those core values which will guide us in carrying out our mission. These values are directly related to our customer service and include:

The County has prepared, and is making available to the public, a complete set of standardized plans for construction of Accessory Dwelling Units (ADU’s), or Farmworker Dwelling Units (FDU’s). These standardized plans are free of charge and provide County residents the option to build an ADU or FDU on their property using this standardized design, without the cost or time that is typically needed for a new design. The County of Ventura’s review fees and review time needed for obtaining the Building Permit for this structure are also reduced when using these plans. To see if your property is eligible for construction of ​an ADU or FDU, please review the following information:
