This project traces the history of urban planning in San Francisco, placing special emphasis on unrealized schemes. Rather than using visual material simply to illustrate outcomes, Imagined San Francisco uses historical plans, maps, architectural renderings, and photographs to show what might have been. By enabling users to layer a series of urban plans, the project presents the city not only as a sequence of material changes, but also as a contingent process and a battleground for political power. Savvy institutional actors--like banks, developers, and many public officials--understood that in some cases to clearly articulate their interests would be to invite challenges. That means that textual sources like newspapers and municipal reports are limited in what they can tell researchers about the shape of political power. Urban plans, however, often speak volumes about interests and dynamics upon which textual sources remain silent. Mortgage lenders, for example, apparently thought it unwise to state that they wished to see a poor neighborhood cleared, to be replaced with a freeway onramp. Yet visual analysis of planning proposals makes that interest plain. So in the process of showing how the city might have looked, Imagined San Francisco also shows how political power actually was negotiated and exercised.

A. SUMMARY This dataset delineates parcels with “Taxable Commercial Space” - meaning parcels where one or more property owner(s) and/or commercial tenant(s) are required to file or pay the Commercial Vacancy Tax. The dataset includes the Block, Lot, Parcel Number and Parcel Situs Address for each commercial parcel within the named Districts. Information about each filing received for the parcel is included, such as Filer Type (Owner / Tenant), Filer Name, Parcel Situs Address from the Filing, and Tax Year filed. The dataset also includes whether a parcel is vacant, and if so, the tax rate applied. A single parcel may have multiple addresses and/or filings depending on the number of units and access points. Parcels marked as vacant either reported as vacant in the tax filing or were determined to be vacant by the Tax Collector. All information displayed is subject to audit by the Tax Collector.

If you are a taxpayer and need to update the information displayed, you should re-file https://sftreasurer.org/CommercialVacancy or contact the Tax Collector for assistance.

If you wish to share information about a vacant property subject to the Commercial Vacancy Tax with the Tax Collector to assist with enforcement, visit https://sftreasurer.org/report-vacant-commercial-property

The dataset includes the Block, Lot, Parcel Number and Parcel Situs Address for each commercial parcel within the named Districts. Information about each filing received for the parcel is included, such as Filer Type (Owner / Tenant), Filer Name, Parcel Situs Address from Filing, Tax Year filed, whether the filer reported a vacancy, and if so, the tax rate applied. A single parcel may have multiple addresses and/or filings depending on the number of units and access points. The information displayed is reported by the taxpayers and subject to audit by the Tax Collector.

D. HOW TO USE THIS DATASET The Commercial Vacancy Tax dataset provides detailed information on commercial properties in San Francisco’s designated Neighborhood Commercial Districts and Neighborhood Commercial Transit Districts that are subject to the Commercial Vacancy Tax. This dataset includes key identifiers such as Block, Lot, Parcel Number, and Situs Address for each commercial parcel. It also lists information for each filing received from property owners, and tenants, including whether the filer reported a space as vacant and, if so, the applicable tax rate. Users can utilize this dataset to identify vacant commercial spaces and assess tax compliance.

F. KNOWN USES The Commercial Vacancy Tax dataset is primarily used by the San Francisco Office of the Treasurer & Tax Collector to monitor compliance with the city’s Commercial Vacancy Tax ordinance. It supports enforcement by identifying Commercial Space that may be subject to the tax and verifying reported vacancy status. Additionally, researchers, journalists, and community organizations access the data to study the impacts of vacant storefronts.

The three Van Ness Ordinances of 1856 to 1858 resulted in the creation and mapping of the Western Addition neighborhood of San Francisco. These five manuscript maps were likely made to show the existing land claims in relation to the newly platted streets, parks, and other public spaces. They may have been used in the subsequent resolution of the various land claims. They show many interesting artifacts of the early settlement of the area before it was officially made a part of the city in the mid 1850's. The 1858 date of the five maps is estimated, based on the creation of the Van Ness map in the same year. Part of the Mission district is also covered. A scanned version of this map was georeferenced as part of the Imagined San Francisco project.

Summary Land Use 2020: Land use categories for every parcel in San Francisco. The land use categories are derived from a range of City and commercial databases. Where building square footages were missing from these databases they were derived from a LIDAR survey flown in 2007.

Land use categories are as follows (units are square feet): - CIE = Cultural, Institutional, Educational - MED = Medical - MIPS = Office (Management, Information, Professional Services) - MIXED = Mixed Uses (Without Residential) - MIXRES = Mixed Uses (With Residential) - PDR = Industrial (Production, Distribution, Repair) - RETAIL/ENT = Retail, Entertainment - RESIDENT = Residential - VISITOR = Hotels/Motels - VACANT = Vacant - ROW = Right-of-Way - OPENSPACE = Open Space

Other attributes are: - RESUNITS = Residential Units - BLDGSQFT = Square footage data - YRBUILT = year built - TOTAL_USES = Business points from Dun & Bradstreet were spatially aggregated to the closest parcel, and this field is the sum of the square footage fields

The subsequent fields (CIE, MED, MIPS, RETAIL, PDER & VISITOR) were derived using the NAICS codes supplied in the Dun & Bradstreet dataset, and the previous TOTAL_USES column.

PREDOMINANT LAND USES: - RESIDENTIAL: Housing--from single family to multifamily to high-rise apartment complexes. - CIE - CULTURAL, INDUSTRIAL, EDUCATIONAL:Any cultural, institutional, medical or educational place such as a museum, zoo, hospital, medical center, college, theatre, social service, or membership organization. - MIPS (generally for offices):Management, information, and professional activities such as finance, insurance, and real estate (FIRE), business, legal, and public administration. - RETAIL/ENT(Retail/Entertainment)Shopping and direct consumer services, amusement, recreation and personal services, restaurants and bars -- from neighborhood-serving to region-serving. - PDR (Production/Distribution/Repair):Wholesale trade, showrooms, manufacturing and materials processing, warehousing, repair, businesses, construction, transportation, communications, utilities. - VISITOR:Hotels and motels.PUBLIC:Publicly owned parks, recreation, and open spaces, as well as some highway right of ways. - VACANT:An empty or undeveloped lot. - MIXED USES:Combined uses, such as office and retail, industrial-retail-entertainment, or industrial and office, etc. where no one use predominates. - MIXEDRES (Residential Mixed):Mostly housing with one or more other use (office, retail, industrial)on the ground floor).

The determining factor for a parcel's LANDUSE is if the square footage of any non-residential use is 80% or more of its total uses. Otherwise it becomes MIXED.

In the case where RESIDENT use has some square footage of non-residential use, this is mainly accessory uses such as home businesses, freelancers, etc.
