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 Part (zone text is in Parts 7.03 to 7.32; each zone's source_url is its Part). The consolidation is for convenience purposes only and is not a legal document; the original bylaws prevail. Bylaw 4161, 2024 (June 10, 2024) replaced RS with R-1 and deleted the old R-1, RD, R-2, R-3A and CD-8 sections. The Part 7.01 file on the City's site still lists the old zone names, and the deleted Parts are not posted, so those zones 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.
