Property Search

A Santa Clara County property search can help you identify a parcel, review its assessed value, view an Assessor parcel map, and locate other information maintained by the County. This article explains which official search system to use, what information to prepare, how to interpret the available records, and which office handles questions about assessments, ownership information, parcel mapping, recorded documents, or property tax bills.

The Office of the Assessor provides property information through several online services. Its real property search, interactive map, and mobile home search serve different lookup needs. The Department of Tax and Collections operates a separate secured property search for tax accounts and payments. Choosing the system that matches your purpose helps prevent confusion between a property record, an assessed value, and an amount due.

Which Property System Fits Your Task?

For basic information about real property, begin with the Assessor’s Real Property Search. The Assessor describes its property search services as providing free access to information such as assessed values, Assessor’s parcel numbers, document numbers, property addresses, mailing addresses, and parcel maps.

The main distinctions are:

Real property search: For locating property information using an address or parcel number.

Interactive map: For searching through a map rather than relying only on an address or parcel number.

Mobile home property search: A separate tool for mobile home records.

Assessed value notification lookup: A separate service for looking up a real property notification of assessed value.

Secured property tax search: For locating tax account information and proceeding through the County’s payment system.

A document number shown in an Assessor record serves a different purpose from an Assessor’s parcel number. Likewise, an assessed value is different from a tax payment amount. Keep these labels with any information you save so you can provide the correct identifier when contacting an office.

Information to Prepare Before Searching

Have the property address or Assessor’s parcel number, commonly called an APN, available before opening a search. The Assessor allows property searches using the first few characters of an address, so a complete address is not always necessary to begin. A parcel number provides another search method when you already have it.

If you are researching several properties, keep each address paired with its corresponding APN. This is especially useful when moving from the Assessor’s property records to the tax search system, or when asking about a map or document number associated with a particular parcel.

Decide what you need from the record before you search. Reviewing an assessed value, researching an indicated sales price, locating a parcel map, and paying a tax bill involve different information or services. A clear purpose also makes it easier to explain a question if the online record does not resolve it.

Address and Parcel Number Searches

The Assessor’s property search supports address and parcel number searches. For an address search, its published instructions allow you to enter just the first few characters. This gives you a way to begin identifying a property without entering the entire address.

Once you locate a record, compare the property address and APN with the property you intended to research. Save the parcel number together with the relevant result, rather than keeping a value or document number without its property identifier. That connection matters when reviewing more than one record or discussing a result with County staff.

An APN identifies the parcel in the Assessor’s records; a property address identifies the property’s location. Both are useful, but they should remain in their respective fields when a search form asks for a specific type of information. In the tax search system, the County specifically directs users with unsuccessful searches to confirm that they entered the correct information into the correct fields.

When an Owner Name Will Not Work

The Assessor’s online property system does not allow searches by owner name. It also does not display the names of individual property owners. The County states that these restrictions are consistent with state law.

If your starting information is a person’s name, the online property search does not provide that search method. For an online lookup, use an address, APN, or the map search instead. Public Service at the Assessor’s Office handles verification of ownership information and the sale of ownership information through its available records and services.

Searching Through the Interactive Map

The Assessor’s Office Interactive Map provides a map-based property search option. It is useful when you want to approach the lookup through a property’s location rather than begin with a text search.

Keep the property’s identifiers with any map information you review. If you also open a real property record, compare its address and APN with the parcel you are researching. This helps keep map information and assessment information connected to the same property.

The Mapping & Title I.D. Unit handles mapping questions, legal property description issues, parcel number changes, property splits or combinations, and situs changes. Those subjects belong with that unit rather than the tax billing office. A question about a parcel number change, for example, calls for a different office than a question about an amount due on a tax account.

Mobile Home Property Records

The Assessor provides a dedicated Mobile Home Property Search. Its property records information describes this as a special tool for nearly 10,000 mobile home properties.

Use this separate service when your search concerns a mobile home. The County identifies mobile homes among the subjects handled by the Assessor’s Business Division. That division is therefore the appropriate Assessor contact for mobile home questions, while general real property valuation questions belong with the Real Property Division.

What the Property Record Shows

The Assessor’s Property Maps and Records information describes the basic property information available free of charge. Depending on the information displayed, a record may include:

Assessed value.
Assessor’s parcel number.
Document number.
Property address.
Assessor parcel maps.
Mailing address.

Read each field according to its label. The property address and mailing address are separate pieces of information. If your question concerns changing a mailing address, the Assessor’s Address Changes service handles that subject. If it concerns a situs change, the County directs that type of issue to the Mapping & Title I.D. Unit.

A document number can also help identify the recorded document associated with information you are reviewing. The Recorder handles public information about recorded documents. The presence of a document number in an Assessor record does not make the Assessor’s property search the same service as the Recorder’s recorded-document information.

Ownership Updates and Value Dates

The Assessor states that its database is updated weekly to reflect ownership changes. Assessed values, however, are available only for the most recent annual assessment roll closures. These are different update schedules within the property information service.

When reviewing a record after a transfer, keep that distinction in mind. A weekly ownership-related database update does not mean the displayed assessed value is recalculated weekly. The value information follows the annual assessment roll availability described by the Assessor.

This distinction is particularly useful when comparing a property record with information about a recent sale. An assessed value and an indicated sales price are separate figures, and the County expressly states that they can differ.

Assessed Value and Sales Price

The assessed value shown in a property record should not be treated as the property’s indicated sales price. The Assessor allows residents to research indicated sales prices at its office through a list of property transfers that occurred within the preceding two-year period.

For a question about the assessed value itself, the Real Property Division handles general property valuation inquiries. The Assessor also provides a separate Real Property Notification of Assessed Value Look-Up. Select that service when your task concerns the assessed value notification rather than a general property search.

For sales research, the transfer list contains information beyond a single price. The County identifies the following fields:

Buyer or transferee name.
Seller or transferor name.
Assessor’s parcel number and property address.
Land use.
Date of transfer and date of recording.
Document number.
Indicated sales price.

The availability of buyer and seller information on this transfer list is separate from the restrictions on the online property search. The online system does not permit owner-name searches or display individual property owners’ names.

Preparing for In-Person Sales Research

The Assessor makes the transfer information available at its office Monday through Friday, from 8:00 a.m. to 5:00 p.m. Bring the property address or APN for the property you want to research, along with a check or credit card to pay for the information.

The County describes a nominal fee to view one year of transfer information, plus a photocopy charge per page. It explains that the fee covers administrative costs to develop and provide the information. This paid service is distinct from the free basic property information available online or at the office.

The Standards Unit handles access to the two-year list of sales prices and sales verification letters. Direct questions about those services to that unit. Questions about changes of ownership or whether a transfer is reappraisable belong with the Property Transfer Unit.

Property Tax Searches and Payments

The Department of Tax and Collections provides a separate secured property search by property address. Its portal also offers a property parcel number search. Use this system when your purpose is reviewing an item for payment or paying a secured property tax account.

The portal’s instructions tell users to select a search option, enter the required information, and click Search. If no results appear, first confirm that the information is correct and entered in the appropriate fields. The County instructs users to contact the department if they need help identifying the required information. It also says that, when correct information still produces no result, an item may need to be paid in person.

Before paying, review the item details. The portal allows you to open an item from the cart to confirm that it is the one you intended to pay. Its details page also allows you to select a different payment option through the “Change” control beside the current selection. The portal defines payment options as the different amounts that can be paid toward an account.

Multiple Properties in One Transaction

The payment system allows up to 30 items in one transaction. To pay for multiple properties, search for the first APN, locate the item on its details page, and add it to the cart. Return to the home page and repeat for the other properties. Once the desired items are in the cart, proceed to checkout and choose a payment method.

All items remaining in the cart will be paid. Remove any APN or assessment number that you do not want included before completing checkout. The portal may also display a warning if an item’s amount changes after it was added. Review that warning because a previously selected payment option may no longer be available.

Property tax billing questions belong with the Tax Collector. Questions about assessed values belong with the Assessor. Keeping those responsibilities separate helps you reach the office that handles the information you are questioning.

Browser Requirements and Office Access

The real property search, interactive map, mobile home search, and assessed value notification lookup require JavaScript. The tax portal also instructs users to enable JavaScript to continue using its application. If a form does not appear or function, confirm that JavaScript is enabled before proceeding.

Basic property information is also available free of charge through microfiche or computers at the Assessor’s Office, Monday through Friday from 8:00 a.m. to 5:00 p.m. This provides an in-person way to research the property information described by the County.

The Assessor’s website includes page-feedback forms. Those forms instruct users not to include personal information such as a home address, tax ID, or Social Security number. Keep page feedback separate from a property inquiry that requires specific record information.

The Right Office for Record Questions

The Assessor’s Office Phone Directory distinguishes the units responsible for different property questions. Public Service handles ownership verification and available ownership information. The Real Property Division handles general valuation questions, while the Mapping & Title I.D. Unit handles parcel mapping and identification issues.

The Property Transfer Unit handles changes of ownership, corporate and partnership transfers, and determinations of reappraisability. The Standards Unit handles sales verification letters and access to the sales-price list. Recorded-document inquiries go to the Recorder, and property tax billing questions go to the Tax Collector.

Before contacting an office, have the property address or APN ready and identify the specific field or record you are asking about. For example, distinguish a question about the displayed assessed value from a question about the mailing address or document number. The Assessor also has employees who speak Vietnamese, Spanish, and Chinese for users who need translation assistance.

Property Search FAQs

Who handles questions about property tax exemptions?

If your property research raises a question about a homeowners’ exemption or disabled veterans’ exemption, the Assessor’s Exemptions Unit handles those subjects. It also handles church, religious, and nonprofit exemptions. The County’s list of Assessor responsibilities identifies the appropriate unit. A property search result alone does not establish whether you qualify for an exemption; direct eligibility questions to the unit responsible for that exemption.

Does a property record confirm building permits?

Do not use an Assessor property record as confirmation that construction received a building permit. The reference information identifies the County Planning Department as the office for County building permits. If you are researching an addition or other construction, treat the permit question as a separate inquiry. The Assessor’s listed property information does not establish a building’s permit history.

Where can I request secured assessment roll information?

The Assessor lists Information Systems as the unit responsible for sales of secured roll information. If you need to purchase roll information rather than review an individual property, describe the information you need to that unit. The supplied County information does not specify available file formats, delivery methods, or prices, so confirm those details before placing an order.

Who reviews exclusions from reassessment after a transfer?

The Property Transfer Unit handles exclusions from reassessment, including questions involving legal entity ownership and corporate or partnership transfers. If your concern is whether a particular transfer qualifies for an exclusion, identify that issue explicitly. Finding the parcel online does not resolve the exclusion question, and the supplied property search instructions do not establish eligibility or explain the required filing procedure.
