ADUs
Additional Dwelling Units
Smart zoning. High performance. Exceptional ROI.
ADU Solutions
Maximize Your Property. Multiply Your Value.
Ontario's updated zoning regulations now allow up to three residential units on most residential lots. Starlit Homes builds ADUs that are architecturally stunning, financially strategic, and built to our exacting performance standards.
ROI-Focused Design
ADUs can generate $1,500–$2,500/month in rental income while adding 20-30% to your property value. We design every unit for maximum financial return.
Seamless Integration
Our ADUs are architecturally harmonized with your primary residence — matching materials, roof lines, and design language for a cohesive estate aesthetic.
Full Performance Standard
Every ADU receives the same building science treatment as our custom homes: continuous insulation, triple-glazed windows, and verified airtightness.
