Kopman Build designs and builds laneway houses in Richmond Hill — 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 Richmond Hill, 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 a prosperous York Region community.
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 Richmond Hill 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 a prosperous York Region community, 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 Richmond Hill lot as part of our initial assessment.
Building a laneway house in Richmond Hill 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.
