Yes. Tiny houses that are income-producing and have a depreciable building basis qualify for cost segregation. Like other residential rental properties, components such as electrical systems, plumbing fixtures, flooring, and site improvements can be reclassified into 5, 7, or 15-year depreciation schedules—accelerating deductions and increasing cash flow for the owner.
