Rules in the bylaw's general sections (parking, fences, suites, home businesses) also apply, and a lot can have site-specific rules. Amendment Bylaw No. 532, 2026 (April 13, 2026) adds a site-specific short-term rental rule to the R3 zone (s. 6.8.10); it is a separate document (https://radiumhotsprings.civicweb.net/document/21488) and is not in this text.
