This paper aims to define a methodology to infer off-street parking at the scale of a municipality in the province of Quebec. Firstly, a database structure is proposed which allows the storage of estimates coming from multiple inference methods for a given lot, at multiple points in time_x000D_ A first estimation method using the parking requirements laid out in municipal zoning codes is proposed. A database structure is put forward to represent the variety of parking requirement formulations (based on square footage, seating capacity, etc.) present in zoning codes. Then an inference method using Quebec's municipal tax assessment database is tested. The results are discussed within the context of Quebec City._x000D_ Additionally, a web interface is presented allowing practitioners to complete the calculations, visualize the results and to override the proposed estimate manually or through other automatic estimation methods._x000D_ Finally, an Application Programming Interface (API) is proposed to access the results as part of other travel behaviour studies. The proposed API would allow the extraction of parking capacity within a geopolitical boundary or within a given isochrone of a point of interest.
