Kopman Build designs and builds laneway houses in Toronto — as-of-right accessory dwellings at the rear of eligible lots. Full permit management, servicing coordination, and construction under one contract.
Since the City of Toronto and many GTA municipalities expanded laneway housing permissions, homeowners with lane-accessible lots can build a separate dwelling unit at the rear of their property as of right — no rezoning required. In Toronto, this means an opportunity to add rental income, house family members, or create a long-term investment.
Laneway house construction is technically demanding. Servicing (water, sewer, gas, electrical) must be extended from the main house or brought in from the lane. The structure must meet full Ontario Building Code requirements as a separate dwelling. And the design must comply with height, lot coverage, and setback rules specific to Canada's largest city.
Kopman Build manages laneway projects as a complete design-build engagement. We assess lot eligibility, coordinate with a designer or architect, manage the permit process, and deliver the structure. You don't need to manage consultants separately — we bring the complete team.

Laneway house construction in Toronto typically costs $350,000–$650,000+ for a fully finished unit, depending on size (typically 400–1,200 sq ft) and finish level. Soft costs (architecture, permits, engineering) add $50,000–$90,000. Servicing costs vary based on how far utilities need to be extended. We provide a detailed estimate after an initial lot assessment.
In most residential zones in Canada's largest city, laneway housing is permitted as of right if the lot meets the eligibility criteria — lane access, minimum lot dimensions, and setback compliance. A building permit is still required, but a rezoning application is not. We confirm eligibility for every Toronto lot as part of our initial assessment.
Building a laneway house in Toronto typically takes 12–18 months from start to occupancy. Permit acquisition takes 4–10 weeks. Active construction takes 6–10 months. The full timeline depends on design complexity, servicing requirements, and permit queue times. We provide a realistic schedule at the pre-construction planning stage.
