Santa Ana ADU Permit Fees & Cost Calculator
Santa Ana states that ADU projects are subject to application review, permit, and development impact fees, but the city does not publish a simple ADU-specific fee schedule on the pages retrieved here. California law also limits certain ADU impact fees for smaller units, so final charges must be verified with the city, school district, and utilities before filing.
