Historic Tax Credit compliance costs kill sub-$250K rehab projects

The Federal Historic Tax Credit provides a 20% credit on qualified rehabilitation expenditures for certified historic structures, but the compliance process requires three separate NPS applications (Part 1: certification of significance, Part 2: project approval, Part 3: completion certification), architectural documentation meeting Secretary of the Interior's Standards, and ongoing NPS review that can add months to project timelines. For small buildings — and roughly one-fifth of HTC projects are under $250,000 — the fixed costs of compliance (architect fees for standards-compliant plans, NPS application preparation, historic preservation consultant fees, extended project timelines) consume a disproportionate share of the rehabilitation budget, making the 20% credit barely worth pursuing. This matters because small-scale historic buildings in rural towns and small cities are exactly the ones most likely to be demolished or abandoned, and the tax credit program that was designed to save them has a cost floor that effectively excludes them. The structural cause: the NPS review process was designed for large commercial projects and has never been scaled down or simplified for small residential or mixed-use buildings, and there is no tiered compliance pathway based on project size.
