MARICOPA COUNTY, Ariz. (Feb. 20, 2025) - The Maricopa County Assessor's Office is sending Notices of Value to more than 1.7 million property owners this week, about 14 thousand more than last year. These Notices are for real property for the 2026 tax year as Arizona property values are set a year ahead to allow for an extensive appeal process.
Each Notice contains two values, the Full Cash Value (FCV) and the Limited Property Value (LPV). FCV is comparable to market value while LPV is used for property tax purposes.
The median FCV of all six real property types saw an increase, signaling an upward trend in property values has re-emerged after most experienced a decrease last year. Commercial property saw the largest median FCV increase at 7.9%. In contrast, condominiums had the lowest median FCV increase at just 0.7%.
The median LPV of all property types also rose; most saw the standard increase of 5%. This is because of Proposition 117.
Since going into effect in 2015, voter-approved Proposition 117 has governed how LPV is calculated. If there are no significant changes to the property or how it is used, the LPV can increase by up to 5% but never surpass the FCV.
“I am so proud that our team assesses every parcel and property with fairness, equity, transparency, and efficiency,” said Assessor Eddie Cook. “We make it a daily priority to provide best-in-class service, and I am so grateful for my team and all the efforts they make to best serve the residents of Maricopa County.”
Property owners have sixty days after the mailing date printed on their Notice to file an administrative appeal with the Assessor’s Office if they believe their property has been improperly valued or classified.
The Maricopa County Assessor's Office encourages property owners to review their Notices of Value and reach out with any questions or concerns. Online resources are available to assist property owners in understanding the valuation process and the factors influencing their property values, including a brand-new educational video for the 2026 Notice of Value and a list of FAQs.
They can also contact our office by calling 602-506-3406 or emailing [email protected].

MESA, Ariz. (Dec. 13, 2024) – The Maricopa County Assessor’s Office has been recognized by the Arizona Association of Counties (AACo) with a 2024 Summit Award for its dynamic training program and Team Development and Collaboration initiative.
The prestigious Summit Award in Employment & Training highlights exceptional efforts in workforce development and innovation, and the Assessor’s Office stood out for its commitment to empowering its team. The Team Development & Collaboration initiative was implemented as part of the office’s Strategic Plan in 2021 to address skill gaps, foster professional growth, and enhance overall employee satisfaction.
Since its launch, it has achieved a remarkable 290% increase in employee training hours and contributed to significantly improved employee retention and promotion rates.
“We are deeply honored to receive the Summit Award,” said Eddie Cook, Maricopa County Assessor. “Our employees are the backbone of our office, and this initiative was designed with their success and professional development in mind. The results have been incredible, and this recognition affirms our commitment to investing in our team.”
Another initiative established in the Strategic Plan was the Digital First initiative, which centered around the deployment of a new mass appraisal system, AA-GAMA. With the rollout of AA-GAMA, our training team tailored courses and sessions dedicated to learning the new system. This robust and thorough training curriculum was another component of AACo selecting the Maricopa County Assessor’s Office for the 2024 Summit Award.
The Maricopa County Assessor’s Office serves one of the nation’s largest counties, with a mission to provide accurate and transparent property assessments while delivering exceptional service to the community. This award reinforces the office’s dedication to operational excellence and its role as a leader in local government.
