Basement Renovation FAQ — Etobicoke
How long does a basement renovation take in Etobicoke?▼
A full basement renovation in Etobicoke is typically completed in 3–4 weeks, depending on scope, layout changes, and whether a basement bathroom or second-suite kitchen is being added. Our crew follows a structured schedule to keep progress predictable.
Do I need a building permit for a basement renovation in Etobicoke?▼
Yes — Etobicoke falls under the City of Toronto, so basement finishing requires a City of Toronto building permit, plus electrical (ESA) and plumbing permits when those trades are involved. Ceiling height (typically 6'5" minimum finished), egress windows, and fire-separation rules all apply. We pull all permits and coordinate inspections as part of the renovation.
How much does a basement renovation cost in Etobicoke?▼
Most Etobicoke basement renovations range from $25,000 to $40,000, depending on finishes, flooring choice, bathroom addition, and any structural or electrical upgrades. We provide clear, itemised proposals so you know exactly what is included.
Can I add a second suite (basement apartment) in Etobicoke?▼
Yes — the City of Toronto permits second suites in most residential zones in Etobicoke, subject to egress, fire-separation, parking, and minimum-size requirements. Multiplex zoning expanded recently, so many Etobicoke lots can now legally support up to four units. We confirm what is allowed for your specific property before quoting.
Which Etobicoke neighbourhoods do you serve?▼
We work across all of Etobicoke — The Kingsway, Royal York Gardens, Humber Bay Shores, Mimico, New Toronto, Long Branch, Islington Village, Markland Wood, Princess Anne Manor, Richview, Sunnylea, and Eringate. Our crew comes in from our Mississauga shop daily, so commute times are short and material runs stay efficient.
