Civ. Code, § 905

If a homeowner seeks to enforce Chapter 2 (commencing with Section 896), in lieu of the enhanced protection agreement in a subsequent litigation or other legal action, the builder shall have the right to have the matter bifurcated, and to have an immediately binding determination of his or her responsive pleading within 60 days after the filing of that pleading, but in no event after the commencement of discovery, as to the application of either Chapter 2 (commencing with Section 896) or the enhanced protection agreement as to the deficiencies claimed by the homeowner. If the builder fails to seek that determination in the timeframe specified, the builder waives the right to do so and the standards set forth in this title shall apply. As to any nonoriginal homeowner, that homeowner shall be deemed in privity for purposes of an enhanced protection agreement only to the extent that the builder has recorded the enhanced protection agreement on title or provided actual notice to the nonoriginal homeowner of the enhanced protection agreement. If the enhanced protection agreement is not recorded on title or no actual notice has been provided, the standards set forth in this title apply to any nonoriginal homeowners’ claims.
