Renovation Permit Fees Compared Across the GTA (2026)

Every building department in the GTA prices residential renovation permits the same basic way: you pay either a minimum fee or a per-square-metre rate on the work area, whichever is higher. For 2026, the minimums run from $200 in Oakville to $377 in Burlington, with Toronto at $214.79, Mississauga at $244, Milton at $264.20, Hamilton at $283 and Brampton at $326.21.

The minimum only tells part of the story. A small bathroom or basement scope in Toronto can come in near the minimum — roughly $215 to $600 — but a typical multi-trade renovation package that includes building, plumbing and mechanical permits plus zoning review lands around $700 to $3,500 once everything is tallied.

Two things to keep in mind when comparing. First, these schedules move every year: Toronto adjusts each January 1 (2026 rates are about 4% above 2025), Burlington approved a 5.35% increase effective April 1, 2026, and Hamilton has proposed increases beyond its posted schedule. Second, the building permit never covers electrical work — that is a separate ESA notification in every municipality, which we cover below. Our guide to building permits in Toronto walks through when a permit is required in the first place.

Here are the posted residential rates most relevant to renovations, from the schedules in force in 2026:

• Toronto: minimum $214.79; interior alterations $11.53/m²; basement finishing about $6.20/m²; plumbing $23.20 per fixture
• Mississauga: minimum $244; interior alterations $6.84/m²; basement finishing $5.64/m²; plumbing $42.23 per fixture; a $50 online application deposit is credited toward the fee
• Brampton: minimum $326.21 — the highest minimum of the seven
• Oakville: minimum $200; interior alterations and basement finishing $4.90/m²; decks $220 flat
• Burlington: minimum $377; interior alterations $8.25/m²; expect roughly 5% more after the April 2026 adjustment
• Milton: minimum $264.20; interior alterations and finished basements $6.55/m²; decks $163.11 flat
• Hamilton: minimum $283; basement finishing $3.94/m²; flat $500 for a second unit inside the house and $1,000 for a detached garden suite

Treat these as current published schedules rather than gospel — Halton Hills posts its own annual schedule too, and every city updates figures yearly. We confirm the exact fee against the live schedule before quoting any client, and you should too before locking a budget.

On minimums, Oakville wins at $200 and Burlington sits at the top at $377. But per-square-metre rates flip the picture for bigger scopes. Toronto charges $11.53/m² for interior alterations — more than double Mississauga's $6.84 — so a 100 m² main-floor renovation runs about $1,150 in permit fees in Toronto against roughly $684 in Mississauga and $490 in Oakville. For basement finishing, Hamilton is the bargain at $3.94/m², and its flat-fee pricing for second units ($500 in the house, $1,000 for a detached garden suite) is a deliberate incentive that undercuts area-based pricing everywhere else in this comparison.

The penalty structures differ too. Start work before your permit issues and Toronto adds a surcharge of 50% of the permit fee. Oakville adds 50% up to a $5,000 maximum, while Burlington charges the full permit fee a second time on most residential scopes. Skipping the permit entirely risks Building Code Act fines of up to $50,000 for a first individual offence, plus stop-work orders and possible removal of finished work for inspection — the few hundred dollars saved is never worth it.

The building permit is rarely the whole permit bill. Three add-ons catch homeowners off guard.

Every electrical scope needs an ESA notification, filed by a licensed electrical contractor — minimum $92, typically $90 to $300 on a bathroom, kitchen or basement renovation, and usually built into the electrician's quote. It's a completely separate system from city hall; the difference is explained in our answer on ESA electrical permits versus building permits.

Plumbing rides on per-fixture fees in most cities — $23.20 per fixture in Toronto, $42.23 in Mississauga — so a new basement bathroom with four fixtures adds real money, especially in Peel.

And if your lot backs onto a ravine, floodplain or the Niagara Escarpment — common around Dundas, Ancaster, Waterdown, Georgetown and parts of Milton and rural Burlington — conservation authority permission or an NEC permit may be needed before the city will issue anything. On regulated lots, budget roughly $500 to $3,000 extra and one to three additional months. These are classic hidden soft costs that never show up in a construction quote.

Ontario legislates a 10-business-day first review for houses — but the clock only starts once your application is complete, and every resubmission after a deficiency letter restarts a cycle. Real-world 2026 numbers look different. In Toronto, a straightforward interior-alteration permit with complete drawings typically clears in about 4 to 6 weeks; incomplete or zoning-flagged files run 8 to 14 weeks. Mississauga publishes averages of about 7 weeks to issuance for a residential alteration and 10 weeks for a second unit, with a 7-to-10-business-day prescreen before the legislated clock even starts. Brampton reviews complete applications within 10 business days under its standard service.

Toronto's Express Services stream (formerly FASTRACK) is the outlier: eligible small residential projects — interior alterations, basement work including underpinning and walkouts, decks, standalone plumbing — can see examiner review within about 3 business days and a permit roughly 5 business days after a clean, zoning-compliant submission.

Build at least one resubmission cycle into your schedule regardless of city, and if a file stalls, see our answer on why building permits get rejected or delayed in Toronto.

Permits belong in your soft-cost line, not your contingency. For a typical multi-trade renovation, set aside $700 to $3,500 for the full permit package and treat anything left over as a bonus. On a $100,000 renovation, the fee difference between the cheapest and priciest GTA municipality is a few hundred dollars — noise compared with labour and materials. Fees shouldn't influence your scope; review timelines should influence your schedule.

What matters more in practice: applying with complete drawings the first time, running permit review in parallel with material selections, and closing the permit with a final inspection so nothing surfaces on a title search when you sell. Open permits are a genuine resale problem across the GTA.
