By limiting length and width, the by law prevents oversized structures that could reduce privacy, block light, or overwhelm smaller lots. The rules help maintain livability, protect community character, and ensure fair use of space across properties. So what are the maximum dimensions allowed?<\/p>\n<p style=\"text-align: justify;\">According to <strong>By-law 810-2018<\/strong>, an ancillary building containing a laneway suite must not exceed:<\/p>\n<ul style=\"text-align: justify;\">\n<li><strong>Maximum Length:<\/strong>0 metres, measured from end to end of the building.<\/li>\n<li><strong>Maximum Width:<\/strong>0 metres, measured perpendicular (at a right angle) to the lot centreline.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong>Example<\/strong><em>: A Garden suite that is 9.5m long and 7.5m wide would comply, but one measuring 11m \u00d7 9m would exceed zoning limits and likely face permit rejection.<\/em><\/p>\n<p style=\"text-align: justify;\">These rules, found in section 150.8.60.30, are in place to regulate the overall footprint of Garden suites.
