Los Angeles ADU Permit Fees & Cost Calculator
Los Angeles ADU fees are typically project-specific and are charged by LADBS based on construction valuation rather than a single fixed ADU permit fee. California’s ADU impact-fee baseline applies: many ADUs under 750 square feet are exempt from impact fees, while larger ADUs may be charged proportionately; school and utility fees still need project-by-project verification.

Fee overview
Do not treat any secondary-source ranges as official fee amounts.
California ADU impact-fee treatment depends on project size and type; verify whether the ADU is under 750 square feet and whether proportional fees apply.
School fees and utility connection fees vary by jurisdiction and utility and require direct verification before budgeting.
The requested scope is a typical residential ADU in the City of Los Angeles, not a JADU-only or multifamily conversion scenario.
The exact LADBS fee schedule and valuation-based calculations were not available in the search results, so project-specific fees are not stated as exact numbers.
Utility fees may involve LADWP or other providers depending on service territory and are not assumed to be city-fixed.
