Mimico's 1930s–1960s bungalows and semis sit on some of Etobicoke's most rapidly appreciating lakefront streets — making a well-executed home addition one of the most compelling renovation decisions in the neighbourhood. Kopman Build has been building home additions across Toronto and Etobicoke since 1999, and we know exactly what it takes to expand these homes properly.
Mimico is in the middle of a generational shift. Long-established bungalow and semi-detached blocks steps from Lake Ontario are being renovated and expanded by buyers who see the neighbourhood's trajectory clearly — and who want to build for the long term rather than move. A home addition in Mimico is often a stronger financial decision than purchasing a larger property elsewhere in Toronto, once land transfer taxes and transaction costs are factored in.
The neighbourhood's compact 1930s–1960s housing stock requires a builder who understands the structural realities of these homes — shallow foundations, older framing systems, and lots that can be tight on coverage. Kopman Build manages everything from structural engineering and permitting through construction and occupancy, with the hands-on oversight that projects in established neighbourhoods demand.
Dustin Kopman founded the company in 1999 after growing up in construction through his family's firm, G&G Enterprise. Every Mimico project is managed by someone who understands the craft — not a project manager reading off a script.

Home addition costs in Mimico are in line with broader Etobicoke and Toronto pricing. A single-storey rear addition on a Mimico bungalow typically runs $200,000–$380,000+ depending on size and finish. A full second-storey addition runs $300,000–$580,000+. Given Mimico's rapid gentrification and lakefront proximity, well-executed additions frequently return strong value at resale. We provide detailed pre-construction estimates before any commitment.
Yes. All home additions in Mimico require building permits from the City of Toronto. Many properties in Mimico are on smaller lots typical of 1930s–1960s development, which can mean setback or coverage issues requiring a Committee of Adjustment minor variance application. Kopman Build manages the full permit and approval process, including any zoning relief needed.
Yes — second-storey additions on Mimico bungalows are one of the most common and financially compelling projects in the neighbourhood. The 1930s–1960s bungalow stock is well-suited to this type of addition: the existing footprint is retained, and a full upper floor effectively doubles the home's living area. Structural assessment and permit approval are required; Kopman Build manages both.
A typical rear addition in Mimico takes 6–10 months from permit approval to completion. A second-storey addition takes 8–14 months. Permitting — including any required Committee of Adjustment hearings — can add 4–9 months before construction begins. We give you a realistic end-to-end timeline at the outset so you can plan accordingly.
