Garden Suite Construction in Georgina

Mid-range 2BR garden suite (700–900 sq ft) runs $380K–$540K all-in (2026 pricing). Studio 300–400 sq ft: $195K–$280K. 1BR 450–650 sq ft: $275K–$380K. 1BR loft: $330K–$460K. Premium 2BR at max 120 m² GFA: $480K–$650K. Hard cost is $400–$650 per square foot; soft costs (design, permits, surveys, arborist, engineering, servicing) typically $50K–$100K depending on site complexity. Modular pre-fab where lot access supports it: $200K–$400K.

Garden suites are permitted as-of-right on every R, RD, RS, RT, or RM zoned lot in Georgina under Bylaw 89-2022 / 849-2025. The main building must be detached, semi-detached, duplex, or row house (not triplex+, not in MCR/CR commercial zones). Practical minimum lot size is roughly 25 ft frontage × 100 ft depth. We start every project with a free zoning verification on Apply.Georgina.ca and a site visit to confirm setback, separation, soft landscaping, and tree-protection feasibility.

Footprint: lesser of 40% of rear yard OR 60 m² (645 sq ft). Total GFA over two storeys: up to 120 m² (1,290 sq ft) via cantilevered second storey, BUT the suite GFA cannot exceed the main house GFA. Maximum height 6.3 m where 7.5 m separation from main house is met (6.0 m if shorter separation). The 45-degree angular plane was eliminated under 849-2025, so flat and shed roofs are permitted. Combined ancillary coverage ≤ 20% of total lot area.

Most garden suite projects within the 89-2022/849-2025 limits are AS-OF-RIGHT and do not need Committee of Adjustment (CoA). CoA is needed when exceeding zoning limits — typically for setback relief, GFA over the main-house cap, or height exceedance on tight lots. CoA fee $1,200 plus planner $3K–$8K, 6–12 week turnaround, ~80% approval rate on garden suite minor variances per recent City monitoring data. We design within as-of-right limits whenever feasible to avoid CoA.

Realistic end-to-end: 8–14 months. Site assessment 1–2 weeks, design and permit drawings 6–10 weeks, plan review 6–12 weeks (Georgina Building, Forestry, Georgina Water), construction 16–28 weeks, final inspections and occupancy 1–3 weeks. Tree Permit adds 6–8 weeks; Heritage Permit adds 4–8 weeks; Committee of Adjustment adds 6–12 weeks. Pre-approved City of Georgina plans save 2–4 weeks at the design stage.

No. Georgina removed parking minimums for ARUs in February 2022, and Bill 23 (Ontario, 2022) prohibits municipalities from requiring parking for ARUs. Two bicycle parking spaces are required (Class 1 — secure, weather-protected — preferred). This is a major change from pre-2022 and dramatically improves project feasibility on small lots.

Georgina Municipal Code Chapter 813 protects any tree ≥ 30 cm DBH (diameter at breast height) on private property and any tree ≥ 10 cm DBH on City property. The Tree Protection Zone (TPZ) is roughly 10× DBH radius. Building within the TPZ requires a Tree Permit and may require root pruning, soil protection, or design changes; the City will not approve removal of a healthy bylaw-protected tree for a garden suite. Arborist report ($1,200–$3,500) is required when within 6 m of a protected tree. Replanting fee in lieu: $640–$2,500 per tree if removal is approved.

Georgina 2026 market rents for garden suites: 1BR (450–650 sq ft) $2,200–$2,800/month, 2BR (700–900 sq ft) $2,800–$3,300/month, premium 2BR with high-end finishes $3,200–$3,800/month. After vacancy (5%), property tax increase (typically $2K–$6K/yr added supplementary bill), insurance, and maintenance reserve, NOI on a $475K mid-range 2BR build is roughly $28K–$30K/yr — a 5.9% cap rate on cost. Property uplift on resale is typically $285K–$320K.

Generally no. Georgina's short-term rental rules require the operator's principal residence — meaning you can Airbnb your main house (where you live), but not the detached garden suite as a standalone STR. Long-term residential rental (one-year lease) is the standard and allowed use. STR enforcement has tightened in 2025–2026; do not plan project economics around Airbnb.

Tarion enrolment requirements for ARUs are nuanced: HCRA / Tarion governs new home construction, and detached garden suites built as ARUs may or may not require Tarion enrolment depending on use. Honest answer: we do NOT claim Tarion enrolment as a default for garden suite projects — confirm with us at the proposal stage based on your specific project structure (rental ARU vs. principal residence, owner-occupier vs. flip). We carry standard contractor liability and WSIB coverage on every project; for projects requiring Tarion, we work with HCRA-registered partners.
