A. SUMMARY In compliance with CA Government Code 6270.5 (passed via SB 272), the City must publish a catalog of enterprise systems that collect data about the public. There are certain exceptions to this detailed in the Government Code. The code is available here. B. HOW THE DATASET IS CREATED This dataset is collated through 2 ways: 1. Ongoing updates are made throughout the year to reflect new or retired systems, this process involves DataSF staff reconciling records at the request of departments 2. Annual bulk updates - departments review their inventories and identify changes and updates and submit those to DataSF for a once a year bulk update - not all departments will have changes or their changes will have been captured over the course of the prior year already as ongoing updates C. UPDATE PROCESS The dataset changes infrequently and is uploaded manually as needed by DataSF staff D. HOW TO USE THIS DATASET Companion dataset inventory dataset A companion dataset of inventoried and published datasets can be accessed online as well.

A. SUMMARY The Municipal Natural Gas Equipment Inventory serves to catalog natural gas-fueled equipment used in municipally owned buildings. This inventory, implemented by the SF Environment Department, aims to establish an understanding of the scope of work needed to electrify municipal buildings and inform an effective and collaborative planning process. This effort was identified as an action in Section BO-2.4 of the 2021 Climate Action Plan and is included in the Environment Code Chapter 7 (Municipal Green Building Requirements). B. HOW THE DATASET IS CREATED The list of buildings required to report data for the Municipal Natural Gas Equipment Inventory was compiled by cross-referencing the City’s Facility Systems of Record and the 2020 municipal benchmarking report to identify all city-owned buildings with non-zero carbon emissions. Numerous municipal buildings are exempt from these reporting requirements, including facilities of the Port of San Francisco and buildings with a primary purpose of providing collection, storage, treatment, delivery, distribution, and/or transmission of water, wastewater, and/or power utilities. Each department received an inventory template, provided by the Environment Department, to submit high level building data and detailed information on each piece of natural gas equipment in use in these buildings. Departments were asked to self-report the required building and equipment data over the course of a 6-month data collection period in 2023 and are asked to keep this inventory up to date in the following years as equipment is replaced. C. UPDATE PROCESS The inventory will be regularly updated by department representatives via the inventory PowerApp. When a gas-powered equipment item is retired or replaced, departments are asked to mark it as no longer in use and provide information on any electric replacement equipment, if applicable. While departments have the flexibility to update the inventory at any time, they are encouraged to do so at 6 month intervals at the minimum. Updated inventory data will be automatically reflected in this dataset. D. HOW TO USE THIS DATASET It is important to note that this dataset does not include facilities of the Port of San Francisco and buildings with a primary purpose of providing collection, storage, treatment, delivery, distribution, and/or transmission of water, wastewater, and/or power utilities, in accordance with Environment Code Chapter 7 exemptions.

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. D. HOW TO USE THIS DATASET See here for an interactive map of all the City lands in this dataset. To track the facilities on City lands, join this dataset to the City Facilities dataset using the land_id field. If you see an error in the data, you can submit a change request with the relevant information to dtis.helpdesk@sfgov.org.

A. SUMMARY This dataset contains a preliminary inventory of artificial intelligence (AI) systems declared by departments within the City and County of San Francisco (CCSF), as part of compliance with Chapter 22J of the Administrative Code. Chapter 22J requires departments and vendors to answer 22 standardized questions about AI technologies that are in use—excluding those used solely for internal administration or cybersecurity purposes. This is an initial release and may not yet reflect a complete list. A comprehensive, citywide inventory will be published by January 2026. For more information, see the full ordinance: Chapter 22J – Artificial Intelligence Tools B. HOW THE DATASET IS CREATED Each City department is required to annually submit an AI inventory as part of their compliance with Chapter 22J. Departments complete a standardized intake form that captures key details about each AI system in use or under consideration. The submitted inventories are reviewed and consolidated by the Department of Technology C. UPDATE PROCESS The full dataset of AI technologies and uses will be published by Jan 2026 and updated every two years D. HOW TO USE THIS DATASET Each row represents an individual AI technology reported by a City department, along with details about its use.
