Why it matters for cost

A license requirement does not set a price, but it sets who may do the work and keeps the company that assesses mold apart from the one that removes it in most of these jurisdictions. Against Angi's published $10–$25 per-square-foot mold rate, the 10 sq ft line is $100–$250 of work (arithmetic, not a published figure). See mold removal cost by location and the licensing guide.
