Rules in the bylaw's general sections (parking, fences, suites, home businesses) also apply, and a lot can have site-specific rules. The City marks the consolidation "for convenience only". The cover lists one amending bylaw, No. 1928 (adopted August 12, 2024, map amendment for 2600 Pleasant Valley Road). 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.
