Murrieta ADU Permit Fees & Cost Calculator
Murrieta’s ADU handout confirms ADUs are allowed by-right with a building permit and sets local size/process rules, but the provided sources do not include a verified city fee schedule. California law also limits local impact fees on ADUs under 750 sq ft, and exact Murrieta-adopted fees should be verified in the city’s current fee resolution and utility/school district schedules.

Fee overview
The supplied sources are not sufficient to verify exact Murrieta permit, plan check, impact, school, or utility fees.
Do not treat contractor blog estimates as official fee schedules.
Verify whether any city fee waivers, credits, or proportional calculations apply to ADUs under 750 sq ft and to larger ADUs.
Murrieta’s current fee amounts were not available in the provided sources, so numeric values are left null rather than inferred.
The parcel may be served by one or more separate school and utility agencies, so those charges must be verified case by case.
California ADU fee rules may change by fee year; the state baseline should be checked against current local adoption records.
