Home Renovation in Oshawa — the short answer
A home renovation is the planned rebuild of existing living space — new layout, new services, new finishes — inside a house you already own. In the Greater Toronto Area in 2026, a kitchen renovation typically costs $25,000 to $75,000, a bathroom renovation $15,000 to $50,000, and a full-floor or whole-home gut renovation $80,000 to $250,000 depending on square footage, structural work and finish level. In Oshawa, structural work, new plumbing and any habitable basement conversion are permitted through City of Oshawa Building Services.
A renovation quote in Oshawa only means something once someone has seen what the house actually is. Central and south Oshawa hold 1920s to 1960s homes — smaller, more affordable, and frequently in need of electrical and plumbing updates alongside the visible renovation. Taunton, Windfields and Kedron are 2005 onward with modern framing and tall basements. The two halves need completely different scopes of work.
Proximity to Ontario Tech and Durham College supports year-round rental demand, which is why second suites are the most common project we are asked about in Oshawa.
Permits — City of Oshawa Building Services
Oshawa permits additional dwelling units subject to building permit and registration. Older central Oshawa basements often need ceiling height verified and electrical service assessed before a legal suite is viable, and both are things we check on the first visit.
