The Recorder’s database contains every recorded document affecting Maricopa County properties: deeds, deeds of trust, mortgages, liens, releases, easements, and all ownership transfers. Full-text retrieval covers documents from the last two years. Older records are accessible through the indexed database. Search by name, legal description, address, or document type. Viewing documents online is free; purchasing official copies costs $1 per page, $3 per certified copy.

This is the definitive source for chain of title. The most recently recorded deed shows the current legal owner. The Recorder’s Office is at 301 W Jefferson Street, Suite 200, Phoenix. Phone: 602-506-3535.

The GIS Parcel Viewer is an interactive map showing every parcel in the county with lot lines, parcel boundaries, and parcel numbers visible. Zoom to any area and click on a parcel to retrieve the owner name, APN, address, and assessed values. Particularly useful when you know the approximate location of a property but not the address — vacant lots, properties adjacent to a target address, or parcels in unincorporated areas without street addresses. The City of Phoenix also maintains its own parcel viewer at btmaps.com/phoenix/parcels for search by owner name, APN, or address within city limits.

The Treasurer’s portal shows the taxpayer of record — the owner or entity responsible for paying property taxes. Search by parcel number, owner name, or address. Results include: owner name, legal description, current and historical tax bills, payment status, and delinquency history. Delinquent tax records appear here before they appear in the Assessor’s database. The Treasurer’s search is particularly useful when the Assessor shows a trust name, because the tax notice is often mailed to a specific trustee or managing member whose name may appear in the Treasurer’s records. Phone: 602-506-8511.

When the Assessor or Recorder shows an LLC or corporation as the property owner, the Arizona Secretary of State’s entity database is the next step. Enter the exact entity name as it appears on the assessor record. Results include: the entity type, filing date, current status (active/inactive), statutory agent name and address, and in many cases the organizer or incorporator names and addresses.

The statutory agent is the registered point of contact for the LLC — this is the person or company that receives legal notices. The organizer or incorporator is often the actual property owner. Note: LLCs do not have to name their members publicly in Arizona, so identifying the beneficial owner of a single-member LLC may require additional steps even after this search.

How to access: From the Assessor parcel page, click “DEED” in the top menu — this opens the current deed directly in the Recorder’s system.

This shortcut links the Assessor’s property record directly to the most recently recorded deed in the Recorder’s system. The deed shows: grantor (seller), grantee (buyer/current owner), date of transfer, legal description, and often the vesting language that specifies how ownership is held (individual, joint tenancy, community property, trust, LLC). The vesting language on the deed is the most legally precise description of who holds title and in what form.

Access via: Maricopa County Treasurer’s website; search by document code “Notice of Trustee Sale” in the Recorder’s database

Properties with delinquent taxes appear in the Treasurer’s tax lien sale portal. A search on the Recorder’s database for “Notice of Trustee Sale” reveals properties in the foreclosure pipeline. Both databases display current owner information. For investors tracking distressed properties in the West Valley, this is a useful identification method for properties whose owners may be open to a pre-foreclosure conversation.

The Arizona State Library Archives maintains historical property records and archived documents that supplement county records. Useful for research on older properties, historic deed chains, or documents from before the county’s online databases were established. The State Library’s digital collection includes plat maps, historic land surveys, and some early 20th-century property records. For most current ownership inquiries, the county systems are faster — but the State Library fills historical gaps that the online county databases may not cover.

Examples: CoStar, PropStream, BatchLeads, ATTOM Data

Commercial data platforms aggregate county assessor, recorder, and multiple other public record sources into searchable databases with bulk export capability. These are the tools real estate investors use for skip tracing — identifying the person behind an LLC or trust entity by cross-referencing multiple data sources including tax addresses, phone numbers, email addresses, and associated entities. Subscription costs vary from approximately $50 to $500+ per month depending on access level and search volume. For a one-time ownership lookup, free county resources are sufficient. For investors building contact lists across dozens of properties, these platforms provide efficiency and skip-trace depth that public sources cannot match.

Best for: Quick sale history and listing agent contact; not reliable for current ownership

Major real estate portals display sale history, listing agent information, and sometimes tax records pulled from public sources. These are useful for a quick check of when a property last sold and at what price, but they are not primary ownership sources — their data lags behind county records and may not reflect recent transfers. Use these portals for preliminary research, then verify current ownership through the Assessor or Recorder before acting on the information.

Best for: Complex ownership chains, LLC/trust beneficial owner research, pre-purchase verification

A professional title search, performed by a licensed Arizona title company or real estate attorney, traces the complete chain of title — every recorded ownership transfer dating back decades — and identifies all outstanding liens, encumbrances, easements, and ownership questions. Title companies have access to the same public records but add professional interpretation, historical depth, and the ability to issue title insurance based on their findings. This is the appropriate standard when: a property has complex entity ownership; public records show inconsistencies or gaps; you need a formal written report; or you are preparing to purchase the property. Phoenix title companies include local firms and national underwriters with Arizona offices.

Best for: Vacant homes, unresponsive owners, off-market outreach

For vacant or abandoned properties where public records show an entity name and no obvious contact, two additional approaches are available. First, the USPS Address Forwarding — if mail is being forwarded from the property, the post office has the forwarding address on file. A written request to the local USPS office, combined with a demonstrated legitimate purpose (such as a real estate transaction), can sometimes yield a forwarding address. Second, Maricopa County Recorder Notice of Trustee Sale documents for properties in foreclosure name the trustee and beneficiary, providing direct contact information. Neither approach requires any paid subscription and both are legally permissible for legitimate research purposes.
