Professional Garden Suite in Richmond Hill

Last updated: March 12, 2026

Richmond Hill permits detached garden suites under By-law 130-2019, with a minimum lot area of 400 square metres and a maximum unit size of 89 square metres — notably larger than Toronto's 60 square metre limit. Konstruction Group provides the framing, insulation, and drywall for garden suite construction across Oak Ridges, Jefferson, Bayview Hill, and Mill Pond.

Richmond Hill Garden Suite Regulations

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 through the City of Richmond Hill 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.

Why Richmond Hill Stands Out for Garden Suites

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.

Rental Income Potential in Richmond Hill

A one-bedroom garden suite in Richmond Hill rents for approximately $2,100 to $2,600 per month based on 2025 CMHC and rentals.ca data for York Region. That translates to $25,200-$31,200 in annual gross rental income. Against construction costs of $250,000-$475,000, a Richmond Hill garden suite delivers a gross rental yield of roughly 7-8% at midpoint costs. Richmond Hill's 89-square-metre footprint allowance — 50% larger than Toronto's cap — means homeowners can build spacious two-bedroom units that command rents at the upper end of the range, improving the overall return on investment.
