Lake Forest ADU Permits

Lake Forest reviews ADU applications ministerially under California state law, which means no neighborhood hearing is required and the city must approve or deny a complete application within 60 days. The city follows state standards, including detached ADUs up to 1,200 square feet and no added parking for units within a half mile of transit, and under AB 670 an HOA cannot prohibit an ADU. Vision ADU handles the full submittal, plan check, and inspections. Permit and impact fees vary by city and project, so we provide a written estimate before you commit (an estimate only, not a guarantee).
