AZ HB2315

Creates a property tax exemption for primary residences of Arizona residents that are not subject to mortgages, deeds of trust, or similar encumbrances.

Requires owners to file an initial affidavit with the county assessor to establish exemption eligibility, with subsequent filings only required if the property is no longer used as primary residence or if ownership changes.

Amends sections 42-11152 and 42-11153 to incorporate the new primary residence exemption into existing affidavit and filing deadline requirements for property tax exemptions.

Takes effect only if Arizona voters approve a constitutional amendment at the next general election through House Concurrent Resolution relating to property tax exemptions.
