This is probably one of the most frustrating parts of a renovation because you’re not just asking “how long will this take?”, you really want to ask “when can my life get back to normal?”.
The honest answer is that timelines depend on scope, drawings, permits, inspections, material lead times, but the biggest contributor to timelines is how decisive the homeowner is. Below is the GTA reality. This is what we see across 200+ projects. Plus what cities and the Ontario Building Code actually commit to on paper.

The short answer

*Permits are not always required. Permit review service standards for complete applications in Toronto are generally 10-30 business days depending on building class; if your submission isn’t “complete,” the clock doesn’t start. Minor variances (Committee of Adjustment) or heritage approvals add time.

What actually happens, stage by stage

1) Design and Selections (1-10 weeks)

• ⦁ Inspiration review and site review.
• ⦁ Design and renderings
• ⦁ Selections for the finishes (cabinets, tile, fixtures, flooring)
• ⦁ Engineer involvement if we’re touching structure.
• ⦁ Deliverable: detailed schedule and completed selections.

The clearer the scope, the faster the construction and permit phases will go.

2) Permits & approvals (2-12+ weeks)

• Zoning/Applicable Law (Toronto): many homeowners now get a Zoning Applicable Law Certificate (ZAC) pre-submission to prove compliance. This is what makes your permit application “complete.”
• Building Code review: once complete, the Ontario Building Code sets decision timelines of 10, 15, 20, or 30 business days depending on project class. Houses and ancillary buildings (like garden/laneway suites) are typically on the 10-day standard.
• If you need a minor variance (CoA): plan for a hearing typically within ~60 days of a complete application, plus a 20-day appeal window before issuance.
• If you’re in a Heritage Conservation District or on the Register: heritage permissions may be required and can add time depending on scope.
• FYI: Toronto recently expanded measures (pre-approved plans, professional reliance) that can shave ~4 weeks off some housing approvals.

Permit timelines only run on complete submissions. Incomplete drawings or missing documents stop the clock. That’s why design-build helps.

3) Pre-construction & material orders (1–3 weeks)

• Final site logistics (bin, parking, protection), order long-lead items, lock trades calendar, pre-demo walkthrough.
• For occupied renos we phase noisy/dusty work and set daily site rules.

4) Construction (timelines vary)

Bathroom (2–6 weeks)
Demo → rough-ins → tile/shower pan → drywall/paint → vanity/countertop → glass → trim/finish → ESA/plumbing inspections → clean.
Kitchen (2–6 weeks)
Demo → framing/leveling → rough-ins & inspection → drywall/prime → flooring → cabinets → counters (template + lead time) → backsplash → appliances → finish & final inspection. (Countertop lead time is a common pacing item.) A lot of the time on a kitchen renovation is waiting for long lead time cabinets to arrive as well as finalizing the kitchen design which brings a kitchen timeline to around 8–18+ weeks.

Basement finish (6–18 weeks)
Framing → rough-ins → insulation/vapour → drywall/paint → flooring/trim → finishes → final inspections. Add 1-2 months if the basement is a legal suite, this includes additional building code requirements like firestopping, soundproofing and organizing city inspections.

Additions & whole-home (4–8 months)
Structure/envelope first (foundation, framing, roof, windows), then interior rough-ins, insulation, drywall, finishes by phase. Large-scale Toronto renovations commonly run 6–12 months post-permits.

Laneway/Garden suites (4–8 months build)
Design + approvals 3–6 months; build 4–8 months, depending on site services and winter work.

Why timelines slip (and how you can prevent it)

Top delays we see:

• Incomplete drawings / missing documents → resubmission cycles; permit clock resets. (ZAC + full drawings minimize this.)
• Scope creep mid-build → re-sequencing trades.
•  Lead times (custom millwork, counters, glass) → schedule padding is mandatory.
• Surprises in older homes (asbestos, knob-and-tube, structural shims).
• Inspection cadence (City, ESA, plumbing) → timing must be pre-booked.

What we do differently:

• Permit-ready design (architectural + structural) to meet “complete application” status on Day 1.
• Zoning pre-checks and variance strategy before you fall in love with a layout.
• Procurement first: we order long-lead items before demo.
• Occupied-home playbook: dust control, quiet hours, weekly calendars, and a single point of contact.

FINAL THOUGHT

Renovations are a lot of planning. If you want a realistic start date (and an end date you can trust), the work has to start with a defined scope and complete drawings. Decisions have to be made early, and you must work with a contractor who tells you the truth even when it’s inconvenient.
