What an ADU Costs in Santa Ana

Santa Ana can offer a practical path to a permitted ADU because many older lots already have detached garages with alley access. That can simplify staging and keep a conversion scope more predictable, while a new detached unit depends more heavily on size, utilities, site conditions, and finishes. Strong year-round rental demand remains an important planning factor. Vision ADU provides a written, itemized estimate after a free feasibility check. Use the 2026 ADU cost calculator →

Santa Ana ADU Permits

Santa Ana ADU applications are handled by the city's Planning and Building Agency and reviewed ministerially under California state law — no neighborhood hearing, and the city must act on a complete application within 60 days. State standards apply, including detached ADUs up to 1,200 square feet and no added parking within a half mile of transit; historic districts like Floral Park may involve design-sensitive plans, which we prepare accordingly. Vision ADU handles the full submittal, plan check, and inspections. Fees vary by project, so we provide a written estimate before you commit (an estimate only, not a guarantee).
