Mello-Roos Bonds and Taxes Disclosure
A third-party, such as californiataxdata.com can aid in this disclosure
The Mello-Roos Community Facilities Act of 1982 authorizes the formation of community facilities districts, the issuance of bonds, and the levying of special taxes to finance designated public facilities and services. The seller of a property consisting of 1 to 4 dwelling units subject to the lien of a Mello-Roos community facilities district or subject to a fixed lien assessment collected in installments to secure bonds issued pursuant to the Improvement Bond Act of 1915 (Division 10, commencing with Section 8500, of the Streets and Highway Code) must make a good faith effort to obtain from the district a disclosure notice concerning the special tax and must give the notice to a prospective buyer. If a district notice is not obtained, a notice obtained from a non-governmental source may be used, provided that it clearly and accurately describes the related tax liabilities.
