Housing Production

This dataset is an authoritative inventory of new housing units constructed in the City of Saint Paul from 2010 through the end of 2025. The data originates from two sources: the City's permitting system, and from the City's records on housing affordability. The dataset helps provide a deeper understanding of trends in market rate and affordable housing production. This dataset is updated quarterly, generally by the 15th of the month following the end of each quarter. For the purposes of this dataset, the delineation of "affordable units" is tied to the construction of the new units: does the project — its development financing or the regulatory framework under which it was built — require units be affordable upon the completion of construction? This definition of affordability does not include units that are affordable only because of a post-construction subsidy or other similar subsequent commitment to affordability, such as through the city's Rental Rehab Loan Program or 4d Affordable Housing Incentive Program. It does, however, include units that are affordable under the terms of zoning district-based density bonuses for affordability. Projects built under a zoning-based density bonus currently comprise a very small portion of the larger total, and are identified in the Notes column of the associated table. This dataset will be updated quarterly, given the manual work currently involved in bringing it up-to-date. It is the product of work over five years across three City departments. Field definitions are available below. In addition to being available for download through the Open Information website, this data is perhaps more easily accessible in an interactive Housing Production Dashboard. This data is designed under a methodology specific to the City of Saint Paul. Other government entities use the same originating permit data, but somewhat divergent methodologies, which can produce very different results. We believe this particular methodology gives the fullest and most timely depiction of housing production available. For specific details, see the "Methodologies Compared" tab at the bottom of the Housing Production Dashboard. Technical details This dataset is generally designed to have one record (row) per building project that creates new units. A project may be the result of one or more building permits. In cases when a project contains both subsidized / affordable and unsubsidized / market rate units, the project is split across two records (rows). Fields (Columns) Defined PropertyRSN: An internal unique identifier for the address point with which the permit is associated. Property Address: The street address at which the permit work took place. ParcelID: The county-assigned unique identifier for the parcel on which the permit work took place. Type of Work: The kind of work undertaken at the site. CHOICES: New · Addition · Remodel Residence Type: What is the physical form of the dwelling units that were created under this building permit? CHOICES: 2-Family/Duplex · Mixed (Commercial/Residential) · Residential (Multi-Fam) · Single Family Dwelling Dwelling Unit Type: The type of financial structure tied to the new dwelling units created under this permit. CHOICES: Market Rate Unit: Units that did not receive some sort of direct public subsidy or assistance outside normal market sources. Affordable Unit: Units that contractually ensure affordability / access for those in need, at the level of 80% of Area Median Income (AMI) and below. This definition does include units that are affordable under the terms of zoning-based density bonuses, which comprise a very small portion of the overall total. This demarcation of affordable units does not include units that received financial assistance in preparing the site for redevelopment, for activities such as pollution remediation. Further, the affordability included here are only those contractually included at the closing of the development financing of the project, and does not include units restricted as affordable at a later date, such as through the City's 4(d) Affordable Housing Incentive Program, or the Rental Rehab Loan Program. Commercial to Housing Conversion: The units shown were produced by converting formerly commercial space (including retail, commercial, institutional and industrial type uses) into residential space (including single family, duplex, 3-4 unit, multifamily and congregate-type residential uses). CHOICES: Yes: The housing units shown were converted from commercial space. No: The housing units shown were not converted from commercial space. Project Permit Issue Date: The date the first permit was issued for the project that created the new dwelling units. Project Permit Issue Year: The year the first permit was issued for the project that created the new dwelling units. Existing Dwelling Units: The number of dwelling units that existed just prior to the start of the project under the definition of "dwelling unit" in the International Building Code. New Dwelling Units: The number of new dwelling units created under the building permit(s) under the definition of "dwelling unit" in the International Building Code. Total Final Dwelling Units: The number of dwelling units existing upon completion of the associated building permit(s), under the definition of "dwelling unit" in the International Building Code. Notes: This field contains notes on specific unique circumstances. In particular, a few building permits produced both subsidized / affordable and unsubsidized / market rate dwelling units. To make building permits in this scenario function as needed within data systems, we split such permits into two lines, one for each type of unit, and made a notation in this field to reflect that division.本数据集为2010年至2025年末期间，圣保罗市（City of Saint Paul）新建住宅单元的权威统计清单。本数据集的数据来源于两个渠道：圣保罗市的建筑许可系统，以及该市关于住宅可负担性的相关档案。该数据集有助于深入解读市场化住宅与可负担住宅的开发趋势。 本数据集按季度更新，通常于每季度结束后的次月15日前完成更新。 就本数据集而言，"可负担住宅单元"的界定与新建单元的建设绑定：即该项目的开发融资或建设所依据的监管框架，是否要求项目竣工后住宅单元需符合可负担标准？本定义下的可负担性，不包含仅因竣工后补贴或其他类似后续可负担性承诺而符合可负担标准的单元，例如通过该市租赁修复贷款计划（Rental Rehab Loan Program）或4(d)可负担住房激励计划（4d Affordable Housing Incentive Program）提供支持的单元。但本定义包含依据区划区域基于可负担性的密度奖励政策所认定的可负担住宅单元。当前，依据区划密度奖励政策建设的项目仅占总项目的极小部分，相关信息会在对应表格的"备注"列中标注。 鉴于当前数据更新需依托人工操作，本数据集仍将按季度进行更新。本数据集是圣保罗市三个部门历时五年协作完成的成果。字段定义详见下文。 除可通过开放信息官网下载外，用户还可通过交互式住宅开发仪表盘（Housing Production Dashboard）更便捷地获取本数据集。本数据集采用圣保罗市专属的统计方法进行编制。其他政府机构虽可获取同源的许可数据，但采用的统计方法存在一定差异，这可能导致统计结果大相径庭。我们认为，本数据集采用的统计方法能够最全面、最及时地展现当地住宅开发情况。如需了解具体细节，请参阅交互式住宅开发仪表盘底部的"方法对比"（Methodologies Compared）标签页。 ### 技术细节 本数据集通常以单个新建住宅开发项目为一条记录（行）。单个开发项目可能对应一张或多张建筑许可。若单个开发项目同时包含受补贴/可负担住宅单元与无补贴/市场化住宅单元，则该项目会拆分为两条记录（行）。 ### 字段（列）定义 - PropertyRSN：与建筑许可关联的地址点的内部唯一标识符。 - Property Address：许可施工项目对应的街道地址。 - ParcelID：许可施工地块由所在县分配的唯一标识符。 - Type of Work：项目现场开展的作业类型。可选值：New（新建）、Addition（扩建）、Remodel（改造）。 - Residence Type：本建筑许可下新建住宅单元的物理形态。可选值：2-Family/Duplex（双户住宅/复式住宅）、Mixed (Commercial/Residential)（商住混合）、Residential (Multi-Fam)（多户住宅）、Single Family Dwelling（单户住宅）。 - Dwelling Unit Type：与本许可下新建住宅单元绑定的金融属性类型。可选值： - Market Rate Unit（市场化住宅单元）：未接受常规市场渠道以外的直接公共补贴或援助的单元。 - Affordable Unit（可负担住宅单元）：通过合同约定为收入不超过地区中位数收入（Area Median Income, AMI）80%的群体提供可负担住房/入住权限的单元。本定义包含依据区划密度奖励政策认定的可负担住宅单元，此类单元仅占总单元数的极小部分。本可负担单元的界定范围，不包含因场地再开发前期工作（如污染治理）获得资金援助的单元。此外，本数据集所涵盖的可负担性仅指在项目开发融资结算时通过合同约定的可负担条款，不包含后续才被限制为可负担的单元，例如通过该市4(d)可负担住房激励计划或租赁修复贷款计划纳入保障范围的单元。 - Commercial to Housing Conversion：本项所示住宅单元由原有商业空间（包括零售、商业、公共机构及工业用途空间）改造而来，改造后的住宅空间包括单户住宅、复式住宅、3-4户住宅、多户住宅及集中式住宅用途。可选值：Yes（是：本项所示住宅单元由商业空间改造而来）、No（否：本项所示住宅单元非由商业空间改造而来）。 - Project Permit Issue Date：本新建住宅单元项目首张建筑许可的签发日期。 - Project Permit Issue Year：本新建住宅单元项目首张建筑许可的签发年份。 - Existing Dwelling Units：依据《国际建筑规范》（International Building Code）中"住宅单元"的定义，项目开工前已存在的住宅单元数量。 - New Dwelling Units：依据《国际建筑规范》中"住宅单元"的定义，本建筑许可下新建的住宅单元数量。 - Total Final Dwelling Units：依据《国际建筑规范》中"住宅单元"的定义，相关建筑许可完成后地块现存的住宅单元总数量。 - Notes：本字段用于记录特定特殊情况。部分建筑许可对应的项目同时包含受补贴/可负担住宅单元与无补贴/市场化住宅单元。为确保此类许可在数据系统中可正常使用，我们将此类许可拆分为两条记录，分别对应不同类型的住宅单元，并在本字段中备注拆分情况。
