This paper analyzes the spatial potential of detached additional dwelling units (ADUs) in Windsor, Ontario. A new GIS model, which integrates various geoprocessing commands in ArcGIS 10.8.1, is developed to calculate whether the minimum allowable size of a detached ADU can fit within the total buildable area of a residential property, based on the setbacks, the lot coverage requirements, and other factors (such as parking and flood plain areas). The model uses publicly sourced data that were obtained from the City of Windsor's Open Data Portal. More specifically, individual residential parcels and associated building footprints along with street centerlines are used as inputs to the model. The outputs are then categorized into three types (suitable, potentially suitable, and not suitable) to demonstrate where detached ADUs can be built in compliance with the local zoning bylaws, on both an individual lot basis and at an aggregate level. The conducted analysis reveals the potential of existing residential neighbourhoods in a mid-size city, and has many implications for homeowners, policymakers, and researchers with respect to increasing housing supply within current Canadian municipalities.

超越感知：安大略省温莎住宅地块独立 ADU 潜力的空间分析

本文分析了安大略省温莎市独立式附加住宅单元 (ADU) 的空间潜力。开发了一种新的 GIS 模型，该模型集成了 ArcGIS 10.8.1 中的各种地理处理命令，用于根据挫折、地块覆盖要求来计算独立 ADU 的最小允许尺寸是否适合住宅物业的总可建筑面积和其他因素（例如停车场和洪泛区）。该模型使用从温莎市开放数据门户获得的公开数据。更具体地说，单个住宅地块和相关建筑占地面积以及街道中心线被用作模型的输入。然后将输出分为三种类型（合适、可能合适和不合适），以证明独立式住宅单元可以在哪里建造，无论是在单个地块还是在总体水平上，都符合当地的分区章程。进行的分析揭示了中型城市现有住宅区的潜力，并对房主、政策制定者和研究人员在增加加拿大现有城市的住房供应方面具有许多影响。
