Straight, local guidance on what projects cost, how long they take, what the permit process really involves, and how to choose who builds for you, across Burlington, Oakville, and Mississauga.
Renovation Oakville's own default is that most projects need one, so the useful question is whether yours is an exception. Here is where the Town draws each line.
Custom Build Not a ranking. What varies across Burlington is which authority gets a say first: the City, Conservation Halton, the heritage register, or the escarpment.
ADU Each type charges you in something you already own and has to prove something different before a permit issues. That, not a ranking, decides it.
Renovation The dust is not the hard part. What decides how a whole-home renovation feels is what sits behind your walls, and whether a working kitchen survives it.
ADU There is no single ADU price in Ontario. Detached garden suites in the GTHA were reported at $200,000 to $350,000 (2025); converting existing space costs less.
Renovation No single number. HomeStars reports Canada-wide kitchens at $16,402 to $45,618 (2026). Where you land turns on scope, condition, finish level, and surprises.
Custom Build A construction loan releases funds in stages as inspected milestones clear, not as one lump sum, and Ontario law requires a 10% holdback as work is supplied.
Renovation Kitchens, bathrooms, and cosmetic updates recover the most at resale; additions and pools far less, and no renovation is guaranteed to pay back in full.
Renovation No single winner. Ask whether you need more square footage or better use of the space you have, then check your lot, structure, and each option's cost shape.
Custom Build No single figure. GTA custom hard construction runs hundreds per square foot, and Burlington government charges add roughly $89,000 or more before framing.
ADU Mississauga allows up to two additional units per property, three total with the house. Sizes and setbacks depend on your zone, so confirm with the City first.
Custom Build A custom home in Ontario runs through four phases and can't legally start without three approvals: a building permit, an HCRA licence, and Tarion enrolment.
Custom Build Licences, insurance, and Tarion registration are table stakes. The questions that tell you whether a builder is right for your project go deeper than credentials.
ADU The short answer is usually yes, but the details decide it. Lot size, existing structures, servicing, and zoning overlays all shape what's actually buildable. Here's what to look at before you spend money on design.
Renovation Between permits, material lead times, and site work, a whole-home renovation is a multi-month commitment. Here's what actually drives the timeline, and where most schedules slip.
