Summary
Redondo Beach charges no development impact fees on an accessory dwelling unit under 750 square feet of living area. Municipal Code Section 10-2.1506(a)(10) requires larger ADUs to pay impact fees proportionate to the square footage of the primary dwelling unit instead of a flat citywide rate.
No impact fees, as defined in Government Code Section 65852.2(f), shall be imposed on any accessory dwelling unit with a living area of less than 750 square feet. Impact fees for all other accessory dwelling units shall be charged proportionately in relation to the square footage of the primary dwelling unit.

Full Breakdown
2(f) for the definition of what counts as an impact fee. Any ADU with a living area under 750 square feet pays none of those impact fees regardless of the primary dwelling's size. Once an ADU reaches 750 square feet or more, the city charges impact fees proportionately in relation to the square footage of the primary dwelling unit on the lot, rather than treating the ADU as an independent unit for fee purposes. 1506. 2(f); it does not waive standard building permit and plan check fees, which are separate charges tied to the cost of processing the permit itself rather than to development impact.
Violations & Fines
A permit applicant charged full impact fees on an ADU with a living area under 750 square feet can challenge the charge under Section 10-2.1506(a)(10) with the Community Development Department, since the exemption is mandatory rather than discretionary once the size threshold is met.
