Professional garden suite services in Richmond Hill and York Region. Licensed, insured, free estimates.
Planning a garden suite in Richmond Hill? Konstruction Group provides the framing, insulation, and drywall your backyard dwelling requires. Richmond Hill homeowners in Oak Ridges, Jefferson, Bayview Hill, and Mill Pond are building Additional Residential Units to add housing and generate rental income on their properties. We deliver the structural trades — framing through paint-ready walls — under one contract.
Richmond Hill permits Additional Residential Units (ARUs) including detached garden suites under By-law 130-2019. Properties must have a minimum lot area of 400 square metres to qualify. The maximum garden suite footprint is 89 square metres (approximately 958 square feet) — notably larger than Toronto's 60 square metre limit. Richmond Hill encourages gentle densification through ARUs as part of its Official Plan, supporting the province's housing supply goals. A building permit is required and all construction must meet Ontario Building Code standards. Oak Ridges and Jefferson feature particularly large lots that are well-suited for garden suites, often with rear yards deep enough to accommodate the structure with room to spare.
Richmond Hill offers a unique combination of generous lot sizes and a higher maximum garden suite footprint than Toronto. At 89 square metres, Richmond Hill's allowable footprint gives homeowners roughly 50% more floor area than Toronto's 60 square metre cap — enough for a comfortable two-bedroom unit. Neighborhoods like Oak Ridges and Jefferson feature lots that often exceed 600 square metres, providing ample space for a garden suite plus rear yard setbacks. Bayview Hill and Richvale offer similar conditions. Richmond Hill's location along the Yonge Street corridor, with access to the Langstaff and Richmond Hill GO stations, makes garden suites appealing to renters commuting into downtown Toronto. The town's family-oriented neighborhoods also make garden suites attractive for multi-generational housing, where an aging parent or adult child can live independently on the same property.
You provide architectural and structural drawings. We review framing requirements, identify steel beam or column needs, and confirm scope for Richmond Hill's allowable footprint.
