This data set includes the Office of the Assessor-Recorder’s secured property tax roll spanning from July 1, 2007 to June 30, 2023. It includes all legally disclosable information, including location of property, value of property, the unique property identifier, and specific property characteristics. The data is used to accurately and fairly appraise all taxable property in the City and County of San Francisco. The Office of the Assessor-Recorder makes no representation or warranty that the information provided is accurate and/or has no errors or omissions.

This dataset is updated annually after the roll is closed and certified. This typically happens by August of each year.

A. SUMMARY
This data represents the boundaries of City-owned lands maintained in the City's Facility System of Record (FSR).
Note: Not all lands are within the City and County proper. The City owns properties outside of its boundaries, including lands managed by SF Recreation and Parks, SF Public Utilities Commission, and other agencies.
Certain lands are managed by following agencies which are not directly part of the City and County of San Francisco, but are included here for reference: San Francisco Housing Authority (SFHA), San Francisco Office of Community Investment and Infrastructure (OCII), and City College of San Francisco.

B. HOW THE DATASET IS CREATED
The Enterprise GIS program in the Department of Technology is the technical custodian of the FSR. This team creates and maintains this dataset in conjunction with the Real Estate Division and the Capital Planning Program of the City Administrator’s Office, who act as the primary business data stewards for this data.

C. UPDATE PROCESS
There are a handful of events that may trigger changes to this dataset:
1. The sale of a property
2. The leasing of a property
3. The purchase of a property
4. The change in jurisdiction of a property (e.g. from MTA to DPW)
5. The removal or improvement of the property
Each of these changes triggers a workflow that updates the FSR. The Real Estate Division and Capital Planning make updates on an ongoing basis. The full dataset is reviewed quarterly to ensure nothing is missing or needs to be corrected.
Updates to the data, once approved, are immediately reflected in the internal system and are updated here in the open dataset on a monthly basis.
