ADU’s constructed with kitchens, which include cooking equipment, will need to install an additional septic tank to reduce the load on the existing disposal field. If the existing disposal field is not large enough to accommodate the additional flow or load from the ADU, a new, separate septic system is required for the ADU. Septic requirements will vary by project, for more information on septic requirements, contact Environmental Health at (831) 755-4505.
