Lafayette ADU Permit Fees & Cost Calculator
Lafayette appears to require an ADU application/permit process plus standard building permit fees, but the official public fee schedule does not clearly isolate a dedicated ADU fee. The most reliable official source found is the Lafayette Consolidated Government fee schedule, which shows valuation-based residential permit fees and a separate under-500-sq-ft residential fee category, but the exact ADU applicability must be verified with the city.
