Overview
Richmond Hill's site plan submission guidelines for a building permit that relies on the City's Pre-Approved Reference Models for detached additional residential units. Its first page lists what the site plan, referenced to a current plan of survey under Building By-law 19-24, shows: survey information, soft landscaping, minimum rear, side and flankage setbacks, a hardscaped clear access path to the street, and car and bicycle parking sizes. The second page is a sample site plan of a one-storey detached ARU behind an existing single family dwelling.
