Residential Rental Property Fee To Start

Phoenix --- Effective February 1, 2009, there will be a $10.00 fee for all newly registered rental property and for any changes to the registry for existing registrations. Taxpayers will be able to pay the fee at any of the Maricopa County Assessor Office's.

The Maricopa County Board of Supervisors voted, in early 2008, to adopt A.R.S 33-1902(I) as policy. This allows the Maricopa County Assessor's office to collect a registration fee for residential property that is registered with the County as rental property.

Property owners who wish to submit the Registration of Arizona Residential Property form using the Assessor website may do so with the following link:

County Assessor Russell's 2009 Notice of Change Note

Dear Property Owner:

Enclosed with this message is your 2009 Notice of Change in Property Valuation. You are receiving this notice because there has been a change in, or a change to, your property. A.R.S. § 42-15105 requires that you be notified that we are changing the valuation to your property, because some type of change has occurred.

Over the past few years, the real estate market has been a volatile one. The precipitous drop in the number of Notices of Change that this office is sending out this year aptly illustrates this point. For example, my office sent out 99,025 Notices of Change for tax year 2007, but for the 2009 tax year we are sending out only 55,580; a 42% drop in just two years.

Further illustrating this point is the decline we are seeing in residential building permits. In 2005, 43,256 residential building permits were issued; that number declined to 21,882 last year. Furthermore, only 6,720 residential building permits have been issued through the second quarter of this year.

We at the Maricopa County Assessor's office have tried to be responsive to the volatility and change present in this real estate market. We reduced the Full Cash Value of more than 900,000 single family homes in tax year 2009, and we will likely further reduce most of the homes in the County for tax year 2010.

Thank you for this opportunity to serve you,

Keith E. Russell, MAI
Maricopa County Assessor

Dear Property Owner:

Enclosed please find your mobile unit Notice of Value for 2008.

Market value is an estimated cost to replace your unit less normal depreciation. All other "improvements" are valued using the cost method, adjusted for depreciation and added to the value of the mobile unit. Typical "improvements" include such things as awnings, sheds, decks, and enclosed porches.

My office is committed to providing you with as much information as possible. Accordingly, we provide information to the public in a variety of ways, including, this insert, which we enclose with all valuation notices, and our web site, which contains a variety of assessment information and parcel maps ( In early summer of 2008 our web site will be updated to include information specific to manufactured residential and commercial personal property.

2009 Property Valuation - Press Release

Assessor Keith Russell announces single-family residence values decline nearly 13 percent overall

Approximately 94 percent of all valley home-owners will see a decrease in their 2009 FCV assessment from their 2008 FCV assessment

Phoenix --- Maricopa County Assessor Keith Russell will send out nearly 1.5 million assessments to anyone who owns real property in the county on February 15, 2008. For the first time in many years, the County Assessor's office will report a decline in the median Full Cash Value (FCV) for single-family residences. The 2009 median FCV for a single-family residence in Maricopa County is $199,800, down from $229,500 in 2008.

"The slide in residential home values that we have seen over the past year or two is now being reflected in the notices all property owners will receive in February" said Russell. "The market time period reflected in the 2009 Notice of Value was mid 2006 through the fall of 2007" said Russell, adding that "this [time period] was when the market sales for single-family residences began to show marked declines."

Other types of property in Maricopa County, such as commercial property, vacant land, etc., have not been impacted materially by the troubles in single-family homes. "Market data for these other types of properties have shown strength," said Russell.

Despite the general decrease most homeowners will see in their 2009 FCV, the Maricopa County Assessor's Office would like to remind them not to be confused by a simultaneous increase in the reported Limited Property Value (LPV) on their 2009 Notice. There are two types of values listed on the 2009 Notice. The FCV, which is based slightly below market conditions, is decreasing, but the LPV, which is calculated according to a formula devised by the Arizona Legislature, is not. In fact, the LPV has lagged far behind the FCV in recent years, as it is intended to do when the market shows dramatic valuation increases like it has in the recent past. Property owners should note that the LPV will always attempt to "catch-up" to the FCV, but it can never be greater than the FCV.

Assessor Russell reminds all property owners to review their FCV and ask themselves the following question; "Can I sell my property for this amount?" If the answer is "No" then they should consider filing an appeal. Information on the appeal process is contained on the notice.

Attached is a schedule which details the changes in different property types as well as Break down of change for the single family market by city and zip code.
