Engineered Additional Residential Unit Dwellings
Every site has unique setbacks, lot coverage, and utility access paths. We engineer and construct four distinct typologies calibrated to maximum municipal density allowances.

Legal Walkout Lower-Level Executive Suites
Full-height subterranean conversions with deep concrete walkout excavations, enlarged code-compliant egress windows, resilient channel double-drywall ceiling fire separations (45-minute rating), and independent ERV fresh-air ventilation loops.
Multi-Generational Private In-Law Wings
Ground-level lateral expansions built for aging-in-place family members. Features zero-threshold curbless walk-in showers, 36" wide interior corridors, acoustic sound-deadened dividing party walls, bespoke kitchenettes, and secluded garden patios.
Laneway & Garage Second-Storey Conversions
Vertical additions mounted over existing two-car detached garages or alleyway infills. Engineered with structural steel moment frames, spray-foam thermal floor envelopes, and fully contained water, sewer, and electrical trench connections.
Municipal Garden Suite Regulatory Parameters
While Bill 23 dictates that municipalities cannot prohibit Additional Residential Units outright, each local jurisdiction retains specific engineering bylaws governing rear-yard coverage, maximum building heights, tree canopy preservation, and fire hydrant distance tolerances.
| Municipality | Bylaw Status | Rear Yard Lot Coverage | Max Building Height | Parking Mandate | Permit Turnaround |
|---|---|---|---|---|---|
| Town of Newmarket | Full As-Of-Right | Max 40% of rear yard area | 4.5m (1-storey) / 6.0m (2-storey) | 0 spaces required (Exempt) | 6–8 Weeks |
| Town of Aurora | Full As-Of-Right | Max 45% rear coverage | 4.3m flat roof / 5.5m pitched | 0 spaces required (Exempt) | 6–10 Weeks |
| City of Richmond Hill | Active Bylaw | Max 40% of rear yard | 4.5m (4.0m near rear boundary) | 0 spaces required (Bill 23 override) | 8–12 Weeks |
| Township of King | Estate Regulations | Calculated by acreage & septic capacity | 6.0m max accessory height | 1 on-site parking spot allocated | 8–14 Weeks |
| City of Toronto | Established Bylaw | Max 40% rear yard coverage | 4.0m to 6.3m (based on setbacks) | 0 spaces required | 8–12 Weeks |
Fire Access Route Compliance
Ontario Building Code mandates an unobstructed clear path of minimum 1.0m width from the front street curb to the garden suite entry door, staying within 45m of municipal emergency vehicle access points.
Tree Protection Zone (TPZ)
Heritage and mature trees with diameter at breast height (DBH) over 20–30cm mandate municipal arborist reports and tree protection fencing to avoid severe municipal stop-work orders and fines.
Deep Frost Line Utility Trenching
Sanitary sewage, domestic water, and 100A sub-panel conduits must be precision directional-bored or trenched at a minimum 4.0-foot frost depth directly tied into the primary structure or dedicated utility mains.

Why Building an ADU with a Dual-Licensed Broker-Contractor Protects Your Equity.
"The GTA market is currently littered with unlicensed renovation handymen advertising cheap 'second units'. The tragic reality is that 70% of those units are uninsurable, fail municipal building code egress rules, and will result in strict stop-work orders or denial of mortgage refinancing down the road."
"At 101GROUP, we synchronize every step under one regulatory roof. Because we are licensed general contractors, we engineer code-compliant drawings, secure your building permits, and pour engineered foundations. Because we are licensed mortgage underwriters with 8Twelve, we pre-structure the equity loan so you don’t pay exorbitant secondary bridge rates. And because we are active REALTORS®, we construct with resale liquidity in mind—maximizing every square foot so your property appraises for peak value when you decide to divest."
