A renovation contractor in Mississauga in 2026 typically delivers kitchen renovations from $30,000 – $150,000+, bathroom renovations from $7,000 – $75,000+, basement projects from $30,000 – $300,000+, and home additions from $250 – $650 per square foot fully built. What changes the price and the timeline in Mississauga is less the city as a whole and more the street you live on: a 1970s Meadowvale townhouse, an Erin Mills two-storey, a Streetsville house on Queen Street and a Lorne Park lot with mature oaks each come with different problems behind the walls and different City rules. This guide covers both.

Key Takeaways for Mississauga Homeowners
- Your neighbourhood's age sets the scope. Most of Meadowvale and Erin Mills was built from the 1970s onward, so many homes are now on their original kitchens, windows and electrical panels. Streetsville and Port Credit have much older houses.
- Two heritage conservation districts (Meadowvale Village and Old Port Credit Village) need a heritage permit for most exterior changes, on a fixed City meeting schedule.
- Tree permits: since April 2022, removing or injuring even one private tree 15 cm (6 in) or wider needs a City permit. This matters for additions, garages and new driveways.
- Near the Credit River, its valleys or Lake Ontario, Credit Valley Conservation may need to issue its own permit before the City will.
- More units are allowed: up to three units on a low-rise lot, and fourplexes as-of-right since December 2023. Registering a second unit with the City is free.
- Permit review: the Ontario Building Code gives the City 10 business days to decide on a complete house permit application.

Renovating by Neighbourhood: What Mississauga Homes Usually Need
Meadowvale
Meadowvale was developed as a planned community from 1970, on former farmland west of the original Meadowvale Village. The earlier streets have more townhouses and semi-detached homes; streets built in the 1980s are mostly detached. In the townhouses the most common project is opening the kitchen to the living room and redoing the one or two bathrooms, all inside a narrow footprint where every wall decision matters. Many Meadowvale townhouses belong to a condominium corporation, so anything touching the exterior, a shared wall, the plumbing stack or the structure needs the corporation's written approval before we can apply for a permit. We ask for the declaration and rules at the first visit so this does not stall the schedule.
Erin Mills
Erin Mills started in the 1970s south of Burnhamthorpe Road and filled in northward, with Erin Mills West finished in the mid-1980s, so most houses here were built between 1970 and 2010. Homes from the first phase are now 40 to 50 years old and often still have their original kitchens, windows and smaller electrical service. When owners add a heat pump, an induction range or an EV charger, a panel and service upgrade often has to come first, and it is cheaper to plan it with the kitchen than after. Along the Credit River valley there are pockets of bungalows and custom homes on larger lots, which is where we see most second-storey additions.
Streetsville
Streetsville was incorporated as a village in 1858 and joined Mississauga in 1974. Queen Street and the streets around it still have houses from the 1800s next to post-war homes. Older houses here can hide stone or block foundations, balloon framing and old wiring, so we budget for what opening the walls may reveal and say so in the quote rather than in a change order later. If a property is listed or designated on the City's Heritage Register, exterior work may need heritage approval, and we check the register before design starts.
Port Credit and Mineola
Old Port Credit Village is one of the City's two heritage conservation districts, and exterior changes, additions and new windows there go through a heritage permit, reviewed by a heritage subcommittee before Council or staff decide. The City publishes yearly application deadlines tied to those meetings, so the permit calendar, not construction, often sets the start date. Lots near the lake or the mouth of the Credit River may also sit in a Credit Valley Conservation regulated area. Mineola, just north, has many large treed lots, which brings the tree permit rules below into almost every addition.
Lorne Park and Clarkson
Lorne Park and Clarkson are a mix of original cottages and builder houses from the 1950s to the 1980s on large, treed lots, and full renovations and teardown-rebuilds are common. Most projects here are additions, second storeys and whole-home renovations. Before we draw an addition we map the trees: a footing, a new driveway or even storing materials over a root zone can count as injuring a tree under the City by-law, and the permit and arborist report need to be in place first.
Meadowvale Village
Not to be confused with the 1970s Meadowvale subdivisions, Meadowvale Village is the City's other heritage conservation district, with its own advisory subcommittee and permit deadlines. Interior renovations generally proceed normally; exterior work is where the heritage process applies.
Cooksville and City Centre
Closer to Square One, a large share of homes are condo apartments. Condo renovations here depend on the building's rules for noise hours, elevator bookings, flooring underlay and plumbing changes. See our condo renovation guide for how that works.
City of Mississauga Rules That Change Your Renovation
- Building permits: required to move plumbing fixtures, remove or alter load-bearing walls, change exterior openings, add a unit or build any addition. Under the Ontario Building Code, the City has 10 business days to issue or refuse a complete permit application for a house. Incomplete applications are not held to that clock, which is why we submit complete drawing sets.
- Heritage permits: required for most exterior changes in the Meadowvale Village and Old Port Credit Village heritage conservation districts, and often for designated properties elsewhere. The City posts yearly heritage permit deadlines.
- Tree permits: since April 1, 2022, a City permit is needed to remove or injure one or more private trees 15 cm (6 in) in diameter or larger, including dead trees, and replacement planting is required.
- Conservation authority permits: near a watercourse, floodplain, valley slope, wetland or the Lake Ontario shoreline, Credit Valley Conservation (most of the city) or the Toronto and Region Conservation Authority (the east edge along Etobicoke Creek) may need to approve the work. Their permit is separate from, and comes before, the building permit.
- Additional units: the City allows up to three units on a low-rise residential lot and, since December 2023, fourplexes as-of-right up to three storeys, including a partly above-grade basement unit. A second unit still needs a building permit and must meet the Building Code and Fire Code; registering it with the City is free. See our legal basement apartment guide.
- Electrical and gas: hardwired electrical work is filed with the ESA by a licensed electrical contractor, and gas appliance work needs a TSSA-registered gas fitter.
We prepare and submit the permit package for every project: drawings, a structural engineer's letter where needed, HVAC heat-loss calculations, and any heritage, tree or conservation applications the property triggers.

Frequently Asked Questions
How much does a renovation cost in Mississauga in 2026?
Kitchens run $15,000 – $150,000+, bathrooms $7,000 – $90,000, basements $30,000 – $300,000, and additions $250 – $650 per square foot. Older houses in Streetsville or Port Credit and heritage or tree approvals add cost and time; the table above gives the full breakdown.
Do I need a heritage permit to renovate in Port Credit?
Only if your property is in the Old Port Credit Village heritage conservation district or is individually designated, and generally only for exterior work such as additions, windows, doors, porches and roofing materials. Interior renovations usually only need a building permit.
Do I need a permit to remove a tree for an addition in Mississauga?
Yes, if the tree is 15 cm (6 in) or more in diameter, even if it is dead. The permit also covers injuring a tree, which includes digging footings or driving equipment over its roots.
Can I add a basement apartment in Mississauga?
Yes. Up to three units are allowed on most low-rise lots, and fourplexes are permitted as-of-right. The unit needs a building permit and must meet the Building Code and Fire Code; registering the second unit with the City is free.
I live in a Meadowvale townhouse. What do I need before renovating?
If the townhouse is part of a condominium corporation, get the corporation's written approval for anything that touches the exterior, shared walls, the plumbing stack or the structure. Interior finishes usually only need notice under the building's rules.
How long does a permit take in Mississauga?
The Ontario Building Code gives the City 10 business days to decide on a complete permit application for a house. Heritage, tree and conservation authority approvals run on their own schedules and should be applied for first.
