1. The contractor shall provide notice to each homeowner upon entering into a contract for sale, construction, or substantial remodel of a residence of the contractor's right to offer to cure construction defects before a claimant may commence action against the contractor pursuant to sections 436.350 to 436.365. Such notice shall be conspicuous and may be included as part of the underlying contract signed by the homeowner. In the sale of a condominium unit, the requirement for delivery of such notice shall be deemed satisfied if contained in a public offering statement in accordance with the laws of this state.
2. The notice required by this subsection shall provide time frame guidelines to comply with sections 436.350 to 436.365 for both the claimant and contractor and shall be in substantially the following form:
3. Nothing in sections 436.350 to 436.365 shall preclude or bar any action if a notice is not given to the claimant as required by this section, and the provisions of sections 436.350 to 436.365 shall not apply to any claim of a claimant against a contractor if such contractor failed to provide the written notice required by this section.
4. In those lawsuits originally filed by a contractor against a homeowner, if a homeowner files a counterclaim or an affirmative defense in such lawsuit that includes a claim based on a construction defect allegedly caused by the contractor, then the provisions of sections 436.350 to 436.365 shall not apply to said lawsuit, and the homeowner or association claimant will not be required to adhere to sections 436.350 to 436.365 for those claims made pursuant to the lawsuit, provided a claimant shall be required to follow those provisions for any claim not otherwise covered by said lawsuit.
