Yes, it's a distinct process with its own City-published checklist ('Commercial Tenant Finish/Remodel Plan Submittal Procedure'), and the required submittal package is lighter — no site plan or soils report, and structural/electrical/mechanical plans are only required for the disciplines actually affected by the scope. Fees (general Valuation Chart, 65% plan review fee) and the commercial review timeline are the same as new construction.
