Who Keeps the Official Land Records
Sonoma County uses a single, county-administered system for recording property documents. The Sonoma County Clerk-Recorder-Assessor, particularly the Recorder's Office, manages a variety of land and financial documents for both unincorporated areas and cities within the county.
The Clerk-Recorder-Assessor offers an online index (Official Public Records Search) of recorded property documents, allowing users to search by name, document type, or date. However, official documents may either be purchased online or in person at the Clerk-Recorder's Office.
What Sonoma County Property Records Include
Sonoma County property records are official documents such as deeds, assessor parcel data, tax assessments, and maps that document ownership, property value, boundaries, and real estate transactions within the county.
Sonoma County uses a traditional grantor-grantee recording system, where deeds and other instruments are recorded with the County Clerk-Recorder to establish ownership priority. Individuals may access an online index of filed and recorded land documents, including maps, dating back to 1964. The Clerk Recorder's Office also maintains handwritten record volumes for documents recorded as early as 1835.
How to Access Sonoma County Property Records
A user can access property records in Sonoma County through several methods, such as:
Online Access (Free):
Although California law limits the public display of recorded document images online, you may search the online index of records that shows basic details such as names, recording dates, and document numbers. After locating a specific record in the index, a fee may be required to obtain and download the full document through the county's authorized system.
The Assessor's Office provides a Search Parcel Information page where you may find Assessor Parcel Number, value notices, basic parcel information, and parcel maps.
In Person:
The Sonoma County Assessor-Clerk-Recorder allows in-person access to recorded documents that are not indexed online at no cost. You can view records dating from 1835 to 1979 on microfilm and digital images, and records from 1980 to the present as digital images on a computer in person at the Clerk-Recorder's Office. The office also maintains a cumulative map index for subdivision maps, surveys, and parcel maps.
The Clerk-Recorder's Office is located at 585 Fiscal Drive, Room 103, Santa Rosa, CA 95403. It is open to in-person visits from 8 a.m. to 4:30 p.m. on Mondays, Tuesdays, Thursdays, and Fridays, while business hours on Wednesdays are from 8 a.m. to 3:30 p.m.
By Phone or Email:

The Assessor's Office also allows individuals to request records through the 24 Hour Interactive Voice Response System by calling (707) 565-3010.
E-Recording (Professionals):
The Sonoma County Assessor-Clerk-Recorder does not support the electronic recording of documents. To record documents, people may submit them along with the required payments in the Drop Box outside the office's front door, by mail, or in person at the office.
What's Not at the Registry (But Matters for Property Research)
The Recorder's Office serves as the official custodian for land documents that establish ownership of real estate property, including deeds, leases, records of survey, and homestead declarations. However, this office does not maintain all the records needed for researching property within the county. Parcel cards, assessments, tax records, and payment information are handled by other county offices, including the Assessor's Office and the Auditor-Controller-Treasurer-Tax Collector. At the state level, property tax laws, rates, and assessments are overseen by the California Board of Equalization and the California State Controller's Office.

Sonoma County uses a single, countywide recording system. Property documents are recorded through one consolidated Clerk-Recorder-Assessor office rather than multiple registry districts.
Recorded land documents date back to 1835. Records from 1964 to the present are indexed online, while older records are preserved in handwritten volumes, microfilm, and in-office digital archives.
