Oxnard ADU Permit Fees & Cost Calculator
Oxnard requires a building permit and plan check for ADUs, with plan check fees based on valuation. The city publishes development fee schedules, but the exact ADU fee total depends on project type, valuation, and whether California ADU exemptions apply; state law also limits certain impact fees for smaller ADUs.

Fee overview
I did not find a clearly readable official city fee table in the search results, so exact dollar amounts are not populated.
Unofficial web sources in the search results mention specific fee amounts and thresholds, but those figures should not be treated as verified.
Oxnard properties in the Coastal Zone may face additional review or permitting steps, which can affect total project cost even if not a separate fee.
The ADU is a standard residential ADU in Oxnard, not a multifamily conversion with special utility or fire-code conditions.
The city fee schedule PDF and OpenGov fee portal may contain the exact amounts, but the search results did not expose them clearly enough to extract numeric fee values safely.
California ADU exemption rules may reduce or eliminate some impact fees for smaller ADUs, but exact applicability should be verified against official state guidance.
