East York's dense stock of 1940s–1960s bungalows and Wartime homes makes basement renovation one of the neighbourhood's most in-demand projects — and Kopman Build has been doing it right, with permits, for 25 years. Whether you're converting an unfinished basement into a legal secondary suite or adding livable space to a heavily renovated bungalow, we deliver to Ontario Building Code.
East York is one of Toronto's most active renovation markets. The bungalow and Wartime housing stock that defines the neighbourhood creates a consistent demand for basement legal suites, and the city's Second Suite bylaw has made converting these basements financially compelling — rental income, resale lift, and multigenerational living all drive the work.
But these older homes come with real considerations. Many have ceiling heights of 6'6"–6'8", well below the 1.95m required for a legal secondary suite. Moisture management in foundations from that era requires attention before any finishing begins. And fire separation between units in a bungalow demands careful framing and assembly work that has to be done correctly to pass inspection.
Kopman Build has been navigating exactly these conditions since 1999. Dustin Kopman grew up working in construction through his family's firm, and that hands-on background carries through to every project — we manage permits, underpinning assessments, waterproofing, and inspections as part of a single coordinated scope, not as add-ons that fall through the cracks.
Full secondary suite creation for East York bungalows compliant with Toronto zoning, Ontario Building Code, and City of Toronto Second Suite requirements.

We visit your East York property, assess the existing foundation and ceiling height, and document the project in writing — scope, budget, and timeline.

We manage all City of Toronto permit applications, engineering consultants, and required approvals — nothing falls through the cracks.
Full-time site supervision, weekly updates, and open-book cost tracking throughout the project.
Structured handover with all documentation, inspection sign-offs, warranties, and a 12-month attendance window post-completion.
Basement renovation costs in East York typically run $65,000–$135,000 for a standard finish in a 1940s–1960s bungalow or Wartime home. Legal secondary suites cost $85,000–$155,000+ once you account for egress windows, fire separation, separate mechanical, and permit fees. If ceiling height is a concern — common in the older bungalow stock — underpinning adds $35,000–$85,000 to the project. We provide detailed line-item estimates before any commitment.
Many of East York's 1940s and Wartime-era bungalows have basements with ceiling heights of 6'6"–6'8" or less — below the 1.95m minimum required for a legal secondary suite and often uncomfortable for finished living space. Underpinning or bench-pinning raises the floor to meet code and create headroom. We assess ceiling height in our initial site visit and recommend the most cost-effective approach for your specific foundation.
East York falls within the City of Toronto's Second Suite bylaw, which requires: a minimum ceiling height of 1.95m, egress windows in all sleeping areas, fire separation between units using fire-rated assemblies, a dedicated or separate heating system, an accessible entrance, and smoke and CO detectors meeting Ontario Fire Code. Given East York's dense bungalow market, legal suite conversions are extremely common here and Kopman Build manages the full permit and inspection process.
A standard basement finish in an East York bungalow takes 8–14 weeks from permit approval to handover. A legal secondary suite typically takes 12–18 weeks due to additional inspections and mechanical work. If underpinning is required to address low ceiling heights — a common need in the neighbourhood's older housing stock — add 4–8 weeks before finishing can begin.
