Amend CSHB 329 on page 4, between lines 26 and 27, by inserting: (c) A person is not required to be licensed under this chapter to perform mold assessment or mold remediation in a one-family or two-family dwelling that the person constructed or improved if the person performs the mold assessment or mold remediation at the same time the person performs the construction or improvement or at the same time the person performs repair work on the construction or improvement. This exemption does not apply if: (1) the person engages in the business of performing mold assessment or mold remediation for the public; or (2) the mold remediation is performed in an area in which the mold contamination affects a total surface area of 30 square feet or more.
