Rules in the bylaw's general sections (parking, fences, suites, home businesses) also apply, and a lot can have site-specific rules. The bylaw is organised by part (one part per zone family, with shared use and regulation tables), so zone line ranges cover the whole part. CD3 is deleted in the bylaw. Zones R1a and R1b are subzones of R1 (R1 / R1a / R1b). 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.
