Rules in the bylaw's general sections (parking, fences, suites, home businesses) also apply, and a lot can have site-specific rules. The City publishes the bylaw as one PDF per zone or group of zones (each zone's source_url; pdf_page counts within that PDF, and lines point into the saved combined text). The City says the office consolidation has no Council sanction, is for convenience of reference only, is not the official version and is not admissible in a court of law; certified copies come from the City Clerk. Zones listed as "in progress" by the City (for example ZR5, ZC30, ZA4) are not part of the consolidation and are not listed here. Zone pages are taken from the bylaw text by a research agent and have not yet been reviewed by a person: confirm with the bylaw before you rely on them. How answers are checked.
