AZ HB2589

Establishes an online registry system operated by a third-party contractor under the Arizona Registrar of Contractors to receive and provide access to preliminary twenty-day notices and notices of completion for construction projects, operational beginning January 1, 2015.

Requires preliminary twenty-day notices to be filed (rather than served) with the online registry as a prerequisite to enforce mechanics' lien rights, with the registry indexing filings by owner name, contractor name, project name, lot/parcel number, address, county, tax parcel identification number, and building permit number.

Allows property owners, contractors, lenders, sureties, and title companies to register construction projects with the online registry to track preliminary notices and protect against mechanic's liens, with the owner able to request information from potential claimants within ten days.

Provides immunity from liability to the state and third-party contractor for information filed or searched in the registry, and clarifies that filing in the registry does not constitute constructive notice to purchasers for value without knowledge.

Modifies mechanic's lien procedures by eliminating proof-of-service requirements, allowing notices of completion to be filed with the online registry, and delaying repeal of section 33-992.02 until December 31, 2015, with most amendments effective the same date.
