AZ SB1656

Establishes a C-PACE (Commercial Property Assessed Clean Energy) program allowing municipalities and counties to finance energy efficiency, water conservation, renewable energy, and resiliency improvements on qualifying properties through special assessments.

Creates a voluntary financing mechanism where property owners can enter into special assessment agreements with local governments, with financing provided by private capital providers and repaid through assessments imposed on the property.

Authorizes the county treasurer to collect special assessment installments and charge fees for collection expenses, similar to general property tax collection procedures.

Specifies that special assessment liens have priority over all liens except general property taxes and prior special assessments, and continue through foreclosure or bankruptcy proceedings.

Allows capital providers to enforce delinquent special assessments through property sale procedures and permits local governments to delegate billing, collection, and enforcement responsibilities to program administrators or capital providers.
