Search Maricopa County Assessment Records by APN, Address, Owner Name or Map
Most people searching for “Maricopa County Property Appraiser” need the Maricopa County Assessor. Use the Assessor for parcel records, APN lookup, legal classification, Full Cash Value, Limited Property Value, assessment ratio, assessed value, valuation notices, exemptions and appraisal appeals.
Use the Treasurer when the task is a property-tax bill or payment. Use the Recorder when the task is a deed, mortgage, lien, plat or recorded document. This page keeps those routes separate so visitors do not send the right question to the wrong office.
Start here: Maricopa County has an Assessor, not a Florida-style Property Appraiser
The Maricopa County Assessor locates taxable property, identifies ownership for assessment purposes, establishes taxable values, lists values on the assessment roll and applies legal exemptions. The office also provides parcel maps, property search, eNotices, forms, appeals, valuation relief, personal-property tools and data resources.
Search by APN, address or owner
Start on the official Assessor site. When you find the right parcel, save the APN because you will need it for maps, taxes, appeals and many office questions.
Open Assessor searchSeparate FCV, LPV and assessed value
The Notice of Value shows legal classification, Full Cash Value, Limited Property Value, assessment ratio and assessed value. Those fields do not mean the same thing.

Tax bills and payment questions go to the Treasurer. Deeds, plats, mortgages and liens go to the Recorder’s recorded document system.

How to search Maricopa County assessment records
The Assessor’s search supports several useful routes. The best route is the one with the least ambiguity. Use the APN when you have it. If not, start with a property address, owner name, subdivision, MCR number, city, ZIP code or map-based search.
-
Open the official Assessor website.
Use mcassessor.maricopa.gov and the search box labeled for parcels, addresses and more. -
Search by parcel number when possible.
The Assessor says any APN format works. You can use dashes or no dashes; a split letter may appear after the parcel number. -
Search by owner name carefully.
Enter the owner’s full name and avoid abbreviating the first name. Verify the parcel, address and APN before relying on the result. -
Search by address in a standard format.
The Assessor’s help uses the pattern: number, street direction, street name, street type, city, AZ and ZIP. If the search fails, leave off the street type and try number, direction and street name. -
Use subdivision, MCR, city, ZIP or STR when appropriate.
For larger searches, the Assessor’s help describes subdivision, MCR number, city/ZIP and section-township-range options. -
Use business or mobile-home routes for non-real-estate accounts.
Business personal property may be searched by business name, address, account/roll number, multiple number or lease number. Mobile homes may be searched by owner, address, account number or VIN. -
Open the matching property and save the APN.
Confirm property address, owner display, legal classification, values and assessment ratio before moving to tax, appeal or recorded-document tasks.
APN / parcel number
Use this when you already have a valuation notice, tax bill, recorded-document reference or saved parcel record.
Property address
Use a standard street format. If results are poor, simplify the address and retry without the street type.
Owner name
Owner searches can include common names, trusts, LLCs or stale ownership display. Always verify the APN and address.
APN guide: the Maricopa County parcel number you should save first
The APN is the Assessor Parcel Number. It connects the Assessor record, Parcel Viewer, Treasurer tax search, Recorder research, appeal forms, exemption work and office communications. The Assessor’s parcel-number examples follow a book-map-parcel structure such as 111-11-111-A, and searches may work with or without separators.
| Identifier | What it means | How to use it safely |
|---|---|---|
| APN / parcel number | Primary Assessor parcel identifier. | Use it for the Assessor, Treasurer, maps, appeals and many property questions. |
| Split letter | A letter can appear after the parcel number when a parcel has been split. | Keep the letter if shown; it can identify the correct split parcel. |
| Subdivision name | A recorded subdivision or development name. | Useful for finding groups of parcels, but still verify the individual APN. |
| MCR number | Maricopa County Recorder subdivision/map reference. | Useful for subdivision-level and recorded-map research. |
| STR | Section, township and range. | Helpful for rural or land research when all three parts are known. |
| Situs address vs mailing address | Property location vs address for notices. | Do not confuse a mailing address update with a deed ownership transfer. |
How to read a Maricopa County assessment record
A property record is easier to use when you split it into identity, classification, value, map and tax-routing information. Do not treat one field as the answer to every property question.
| Record field | What to inspect | Common mistake to avoid |
|---|---|---|
| APN | The parcel number used across Assessor, Treasurer and map systems. | Do not rely on an address-only match without saving the APN. |
| Property address | The physical property location, when shown. | Do not confuse situs address with mailing address. |
| Mailing address | Address used for notices or correspondence. | Mailing address is not proof of occupancy, title or residency. |
| Owner display | Assessment ownership information. | It is not a title report and may not reflect every recorded document issue. |
| Legal classification | Arizona class assigned to the property for assessment purposes. | Do not assume a rental, primary residence, commercial or mixed-use classification is correct without checking facts. |
| Full Cash Value | Market-value-related figure used for valuation review. | Do not treat FCV as a guaranteed sale price or private appraisal. |
| Limited Property Value | Value used in Arizona property-tax calculations for most real property. | Do not assume LPV moves exactly the same way as market value. |
| Assessment ratio | Ratio applied to the property’s value based on legal class. | Do not use a residential ratio for every property type. |
| Assessed value | Value after applying the assessment ratio. | Do not confuse it with the final tax bill or Treasurer balance. |
Parcel Viewer and GIS maps: useful for research, not legal boundaries
The Maricopa County Assessor provides a Parcel Viewer and links to GIS resources. The map tools can help locate a parcel, view property and mailing-address details in the side panel, search nearby areas, and connect map results to detailed Assessor property information.

How to use the parcel map without overclaiming
Full Cash Value, Limited Property Value, assessment ratio and taxes
The Assessor’s Notice of Value shows the property’s legal classification, Full Cash Value, Limited Property Value, assessment ratio and assessed value for the current and prior valuation year. The notice is for the upcoming tax year and is not the Treasurer’s tax bill.
Full Cash Value
Full Cash Value is generally tied to market value unless a statute requires a different calculation. It reflects land and improvements and is the value most often challenged when a property owner believes the market value is too high.
Limited Property Value
Limited Property Value was created to limit large increases in taxable value. The Assessor explains that LPV cannot exceed FCV and that Proposition 117 generally limits LPV increases to 5% per year, with exceptions for changes such as added or deleted improvements.
How an Arizona value can move toward a tax estimate
Notice of Value: what it is and what to do with it
The Assessor mails Notices of Value to property owners on or before March 1 each year. The notice tells the owner the legal classification, FCV, LPV, assessment ratio and assessed value for the current and prior valuation year. It is not a tax bill; the Treasurer calculates and mails property tax statements later.
Exemptions, Senior Valuation Protection and valuation relief
The Assessor’s valuation relief programs include personal exemptions and Senior Valuation Protection. These programs have eligibility rules, documentation requirements and deadlines. Do not assume every senior, veteran, widowed person or disabled homeowner automatically qualifies.
Widowed, disabled and veteran categories
The 2026 Personal Exemption Application describes programs for widows/widowers, totally disabled persons and qualifying veterans with disability status. The official form lists an exemption amount of up to $4,873 against assessed LPV for qualifying applicants.
LPV freeze for eligible seniors
The Senior Valuation Protection program may freeze the Limited Property Value of a primary residence for eligible senior homeowners based on income, age, residency and property-value requirements.
Use current-year forms
The Assessor says Personal Exemption applications may be submitted from the first Monday in January through February 28, or from March 1 through September 1 when accompanied by an Exemption Deadline Waiver.
How to apply without missing the required proof
- Open the official Assessor valuation relief page.
- Choose the correct program: Personal Exemption, Senior Valuation Protection or another official relief category.
- Use the current-year application, not an old saved PDF.
- Gather proof of primary residency, income documentation and category-specific documentation.
- For disability claims, use the official disability-certification route required by the form.
- For veteran disability, prepare the Veterans Affairs documentation requested by the application.
- If filing after the regular window, include the deadline waiver when required.
- Submit through the current allowed route: online, email, mail or in person where the Assessor page allows it.
- Save confirmation and later verify the result on the property record or Assessor communication.
Assessment appeals and Notice of Claim options
An appeal is for a property owner who believes the Full Cash Value is above market value or the legal classification is wrong. A Notice of Claim is different: it is used for certain factual errors or legal-classification errors for the current tax year and up to three preceding tax years.
Value or classification dispute
Use the official Assessor appeal page and the Petition for Review of Valuation process when the Notice of Value is still within the allowed appeal period.
Use the notice date
Real property appeals are generally due within 60 days of the Notice of Value mailing date. Personal property and mobile-home notices may use a 30-day period. Always use the printed deadline and current Assessor instructions.
Error correction route
Use Notice of Claim only when the issue fits the statutory factual-error or legal-classification error process. It is not a second chance for every missed market-value appeal.
Appeal workflow
- Open the property record and save the APN.
- Read the Notice of Value and write down the mailing date, deadline, FCV, LPV, assessment ratio and legal classification.
- Decide what is actually disputed: FCV, legal classification, property facts, or another eligible issue.
- Gather evidence before filing: comparable sales, photos, appraisals, repair documents, measurements, permits or primary-residence/classification proof.
- Use the official Assessor appeal page, online appeal option or current AZDOR form referenced by the office.
- Do not send real-property petitions by email if the Assessor page says email is not accepted for that filing type.
- Save proof of timely filing and all supporting evidence.
- If you receive an Assessor decision and need another review, follow the State Board of Equalization or Tax Court instructions that apply to your case.
| Issue | Stronger evidence | Weaker argument |
|---|---|---|
| Full Cash Value too high | Comparable sales adjusted for location, size, condition, age and property type. | One online estimate or a neighbor’s complaint. |
| Condition problem | Dated photos, inspection reports, repair estimates and contractor documentation. | “The house needs work.” |
| Incorrect property facts | Measurements, plans, permits, photos, surveys or other reliable documentation. | Unsupported square-footage claim. |
| Legal classification wrong | Residency records, rental/occupancy facts, voter registration, driver license, tax return address section or utility proof when relevant. | Assuming the class should change without proof. |
| Tax bill too high | Separate value, rate, district, exemption and payment-balance issues before choosing an office. | Filing a value appeal when the real issue is a taxing district levy or payment status. |
Tax bills and payments go to the Maricopa County Treasurer
The Assessor does not compute, mail or collect property-tax bills and does not have payment information. The Treasurer handles property-tax statements, payments, receipts, delinquency information, tax liens and distribution to taxing districts.
How to find a bill
- Search by parcel/account number.
- Search by name or business name.
- Search by mailing or situs address.
- Use VIN where the Treasurer system supports it.
- Verify tax year, amount due and payment status before paying.
Due and delinquency dates
Arizona law generally makes the first half due October 1 and delinquent after November 1 at 5:00 p.m. The second half is due the following March 1 and delinquent after May 1 at 5:00 p.m. If total taxes are $100 or less, the entire amount is due October 1 and delinquent after December 31.
Payment workflow
- Open the official Maricopa County Treasurer property-tax site.
- Search by APN, name, address or another accepted identifier.
- Open the correct parcel/account record.
- Verify owner display, property address, tax year, half-year installment and balance.
- Review current interest, delinquency, lien or special handling messages.
- Choose the official payment method and review any processing-fee language.
- Submit payment only after confirming the parcel/account and tax year.
- Save the receipt or confirmation number.
Deeds, mortgages, plats and liens: use the Recorder
The Maricopa County Recorder records and preserves deeds, plats and many other public documents. The Recorder’s website provides a Recorded Document Search and explains that recorded documents are available and searchable through that system. This is the right route for deed and recording research.
Maricopa County Recorder
Use the Recorder when you need a deed, mortgage, lien, plat, release, recorded date, document search or official copy. The Recorder’s document search supports recorded-document research and full-text retrieval.
Recorder phone: 602-506-3535
Free recorded-document notifications
Maricopa Title Alert is a free Recorder program that monitors names entered by subscribers and sends an alert when documents are recorded under those names after signup. It is a notification service, not title insurance or fraud prevention.
- Find the property in the Assessor search and save the APN, situs address and owner display.
- Open the Maricopa County Recorder’s Recorded Document Search.
- Search by the available fields, such as name, docket/book/page, document details or text search where useful.
- Open the matching deed, mortgage, lien, plat or release.
- Compare parties, legal description, recording date and document type.
- Use the Recorder’s purchasing or copy instructions if an official copy is required.

Common Maricopa County assessment record issues
Address search does not find the property
Try a standard address format with number, direction, street name and abbreviated street type. If the portal still does not return a useful result, leave off the street type or search by APN, owner name, subdivision, city/ZIP or map.
The APN changed or no longer returns a parcel
The parcel may have gone through a split or combine process. Use the information you have and contact the Assessor for parcel-history help instead of guessing a new number.
The Notice of Value is confusing
Read FCV, LPV, legal classification, assessment ratio and assessed value separately. The notice is not a tax bill, and the values shown may affect a future tax statement rather than the bill already in hand.
Taxes increased even though value went down
That can happen because tax levies, rates, districts, overrides, bonds and exemptions also affect the final bill. The Assessor values property; the Treasurer calculates and mails tax statements.
Owner or mailing address looks wrong
For a mailing-address change, use the Assessor’s mailing address process. For ownership or title questions, verify recorded documents through the Recorder first.
The map boundary looks wrong
Use Parcel Viewer for orientation and assessment research only. For legal boundaries, easements or encroachments, use recorded documents, a surveyor, a title professional or an attorney.
Official resources and verification
Use these official sources for live records, forms, filings, taxes, maps and recorded documents. Recheck fast-changing deadlines, forms, portal status, tax rates and payment rules before filing or paying.
Last reviewed: September 1, 2026. Office roles are relatively stable, but appeal dates, current forms, exemption amounts, tax rates, tax statements, payment rules, portal status and office hours can change. Verify the linked official page before filing, paying or making a legal or financial decision.
Maricopa County Property Appraiser FAQs
1. Is there a Maricopa County Property Appraiser?
“Property Appraiser” is a common search phrase, but the official Arizona office is the Maricopa County Assessor’s Office. The Assessor handles assessment records, APN lookup, values, legal classification, exemptions and valuation appeals.
2. What is the official Maricopa County property search?
Use the official Maricopa County Assessor website at mcassessor.maricopa.gov. The search supports parcel number, owner name, address, subdivision, MCR number, city, ZIP, STR, business personal property and mobile-home routes.
3. What is an APN in Maricopa County?
APN means Assessor Parcel Number. It is the main parcel identifier used by the Assessor, Treasurer, Parcel Viewer, appeals process and many property-record tasks.
4. Can I search by address or owner name?
Yes. The Assessor supports address and owner-name search. Use a standard address format, and enter a full owner name without abbreviating the first name. Always verify the APN and property address before relying on a result.
5. What is the difference between Full Cash Value and Limited Property Value?
Full Cash Value generally reflects market value unless statute requires another calculation. Limited Property Value is used for most property-tax calculations and cannot exceed Full Cash Value. It is generally limited in annual growth, with exceptions for property changes.
6. Is the Notice of Value a tax bill?
No. The Notice of Value is prepared by the Assessor and shows values and classification for the upcoming tax year. The Maricopa County Treasurer calculates and mails property-tax statements later.
7. How do I appeal a Maricopa County property value?
Use the Assessor’s official appeal process if you believe the Full Cash Value is higher than market value or the legal classification is wrong. Real property appeals are generally due within 60 days of the Notice of Value mailing date, but the printed deadline and current Assessor instructions control.
8. What exemptions or relief programs are available?
The Assessor administers Personal Exemptions for eligible widowed, disabled and qualifying veteran categories, and Senior Valuation Protection for eligible senior homeowners. Each program has income, residency, documentation and filing rules.
9. Where do I pay Maricopa County property taxes?
Use the Maricopa County Treasurer, not the Assessor. Search by parcel/account number, name, address or another accepted identifier, verify the tax year and balance, then pay through the official Treasurer system.
10. Where do I find deeds, liens or recorded documents?
Use the Maricopa County Recorder’s Recorded Document Search. An Assessor parcel record or map is not a deed search, lien search, title report, legal boundary survey or ownership guarantee.
