How long a GTA renovation really takes: the permit clock, the rules, and what slows jobs down (2026)

From LF Builders, the renovation company behind this forum. Rules checked against the Ontario Building Code, City of Toronto, City of Vaughan and Ontario e-Laws on October 30, 2026.

Short answer: For a house, Ontario’s Building Code gives the building official 10 days, not counting weekends and holidays, from a complete permit application to issue the permit or refuse it in writing. Small buildings get 15 days, large 20 and complex 30. The clock doesn’t start until the application is complete, and it stops if the official finds something missing and tells you in writing within 2 days. Vaughan says complete applications are “usually” processed within those same windows. Most of a renovation’s calendar is everything around that clock: design, revisions, lead times and the trades.

The permit clock

Division C, Article 1.3.1.3 of the 2024 Ontario Building Code sets how long a municipality has to decide on a complete application:

Building Days to issue or refuse
House 10
Small building 15
Large building 20
Complex building 30

Three things decide whether you actually get that timeline:

  1. “Complete” is doing the work. The clock starts the day after the application is complete: drawings, forms, fees and any other approvals it depends on.
  2. The clock can stop. If the official finds documents missing, or a conflict with other applicable law, and tells you in writing within 2 days, the clock pauses until it’s fixed.
  3. It’s a decision, not an approval. Within the window the official must either issue the permit or refuse it in writing with reasons. A refusal starts a revision cycle.

Which code applies to your project

The 2024 Ontario Building Code took effect January 1, 2025. The 2012 code still applies if your permit was issued by December 31, 2024, or if your drawings were substantially complete by that date and you applied before March 31, 2025. Either way, construction has to start within 6 months of the permit being issued.

Before anyone starts work

Time lost to the wrong contractor is the longest delay of all. In Toronto:

  • A renovation business needs a City T85 Building Renovator licence, and Municipal Code Chapter 545 requires it to give you a written contract.
  • Anyone you hire for electrical work must be an ESA Licensed Electrical Contractor (search ESA’s contractor locator). Homeowners may do their own electrical work, but must file an ESA notification first.
  • Gas work needs a TSSA-registered contractor and a certified gas technician. There’s no homeowner exemption.
  • Ontario’s HCRA licence covers new-home builders, not renovators, and Tarion’s warranty is for new homes.

Under Ontario’s Consumer Protection Act, 2002, a contractor can’t charge more than 10% above an estimate they gave you. A contract signed at your home for over $50 must be in writing, and you have 10 days to cancel after you receive your copy. (The Consumer Protection Act, 2023 has passed but isn’t in force yet.)

What slows jobs down

The code covers the permit. Everything else depends on the house and the people, and that’s where this forum is most useful. A member contractor’s take is in Realistic renovation timelines in Ontario: what nobody tells you upfront. Related guides:

Help build real numbers

The legislated window is the same everywhere. What people actually experience isn’t, and nobody publishes it. If you’ve pulled a permit in the GTA since 2025, reply with:

  • your city (Toronto, Vaughan, Mississauga, Markham…) and the type of work,
  • the date your application was complete and the date the permit was issued,
  • anything that stopped the clock, and how you fixed it.

We’ll publish a summary of the replies here once there are enough of them to mean something.
