Maple basements usually start ahead, and that is worth real money
Most of Maple was built from the 1990s onward. That one fact tends to change the budget more than any finish you pick.
Newer homes here went in with taller basement ceilings. So the underpinning conversation that costs fifty thousand or more in older parts of the GTA usually never comes up. A lot of them were also roughed in for a basement bathroom when the house was framed. If yours was, you just saved eight to fifteen thousand dollars before we pick up a tool.
Not every house here fits that pattern. Around the older village core near Major Mackenzie and Keele the homes go back much further, and those basements behave like any other older basement. Headroom and drains both need a proper look.
Working out which one you have takes about ten minutes, and we do it on the first visit. Senso Design has worked as a home renovation company in Toronto and across York Region since 2004, from a facility twenty five minutes from Maple.
Three things we check before we quote your basement
In that order. Each one can move the price by five figures, and none of them show up in a photo.
Headroom
Measure from the concrete to the joists, then take off four to six inches for the finished floor. Take off more where the ducts run. Newer Maple builds clear this without trouble. Older village homes sometimes come up short, and getting that height back means benching or underpinning at $50,000 to $80,000 or more.
The drain
If you want a bathroom and the rough in is already there, you are well ahead. If it is not, we have to open the floor, trench over to the stack and repour. That alone runs $8,000 to $15,000, and it is the biggest swing in most Maple quotes.
Water
If the basement has ever been damp, we sort that out before anything gets framed. Sometimes it is the grading outside. Sometimes it is weeping tile, a sump pump or waterproofing on the inside. Finishing over a water problem is the most expensive mistake in this trade, and it is the job we get called in to undo more than any other.
What people build down there in Maple
Roughly in order of how often we are asked, with what each adds to the budget.
Rec room and family space
$35,000 to $55,000
Somewhere for the kids and the TV. No bathroom means no concrete comes up, so these move quickly.
In-law or nanny suite
$55,000 to $90,000
A bedroom with its own bathroom and a small kitchen, meant for family rather than tenants. Fewer rules apply than with a rental unit, and Maple’s larger homes take one comfortably.
Legal second suite
$90,000 to $140,000+
An apartment you can legally rent out. It needs its own entrance, egress windows, fire separation and a kitchen, all approved through the City of Vaughan.
Bar, gym, theatre or office
Priced within the above
These usually come as part of a bigger basement rather than on their own. A bar needs a sink and a drain. A gym needs a floor that can take the weight. A theatre needs its wiring run before the drywall goes up.
What a basement costs in Maple
2026 figures from our own completed GTA basements, before 13% HST.
The short answer: a basic finish with no bathroom runs $35,000 to $55,000. A mid range basement with a three piece bathroom runs $55,000 to $80,000. A legal apartment with its own kitchen runs $90,000 to $140,000 or more.
| What moves the number | Typical cost |
|---|---|
| Bathroom where no drain rough in exists | $8,000 to $15,000 |
| Underpinning or benching for ceiling height | $50,000 to $80,000+ |
| Separate entrance for a second suite | Varies with grade and access |
| Egress windows and window wells | Required for any bedroom below grade |
| City of Vaughan building permit | $400 to $2,000+ |
A finished basement typically returns 70 to 75 percent of its cost at resale, and a legal suite adds rental income on top. Full method and comparisons in our basement renovation cost guide.
Legal basement apartments in Vaughan
Maple sits in the City of Vaughan, so a second suite is approved through Vaughan rather than Toronto, and it has to satisfy the Ontario Building Code.
- Minimum ceiling height across the living areas, which most newer Maple homes already meet.
- Egress windows in every bedroom, sized so someone can get out and a firefighter can get in.
- Fire separation between the suite and the rest of the house, plus interconnected smoke alarms.
- A separate entrance and a safe exit that does not run through the main dwelling.
- Zoning and parking at your address that permit a second unit.
We go through all of it at the first visit, because there is no sense designing a suite the house cannot legally hold. Our guide to basement apartment requirements covers the detail, and we confirm the Vaughan specifics for your address.

How a basement renovation runs
How long a basement renovation takes
| Scope | Construction time | What extends it |
|---|---|---|
| Rec room, no bathroom | 4 to 6 weeks | Flooring and trim lead times |
| Basement with a bathroom | 6 to 10 weeks | Breaking concrete, inspections |
| Legal second suite | 10 to 16 weeks | Permits, egress windows, separate entrance |
| With underpinning | Add 4 to 8 weeks | Structural work in sections, engineered |
Design and City of Vaughan permit review sit before all of this. We build that window into the schedule at the start rather than discovering it after demolition, which is the most common reason a basement timeline slips.
What our clients say
Senso Design holds a 4.9 star rating across 115+ Google reviews, plus Best of HomeStars five years running and Best of Houzz in 2025 and 2026.
Mark patiently explained everything to us, from planning, design, choices of materials and timeline. Everything went extremely well, from a great design and layout to the hardworking, efficient, well mannered construction crew. The finished product looks fantastic.
We did a major renovation, kitchen, multiple baths, family room, and still love the work they did. From incorporating new ideas to sticking to budget and timelines, they were on point. Their after care has also been superb.
The teams were well coordinated, small issues were resolved quickly, and the final cost matched the original quote. That last part is rarer than it should be.

Maple basement questions, answered
How much does a basement renovation cost in Maple?
Three ranges cover most of what we do here. A basic finish with no bathroom runs $35,000 to $55,000 before HST. Add a three piece bathroom and you are looking at $55,000 to $80,000. A legal apartment with its own kitchen starts around $90,000 and can reach $140,000 or more.
What usually decides where you land in Maple is the bathroom drain. If the rough in is already there, great. If it is not, that one item adds $8,000 to $15,000.
Does my Maple home already have a basement bathroom rough in?
A lot of them do. It became standard practice as Maple was built out from the 1990s onward, so if your house went up in that stretch, there is a good chance the plumber left you a capped drain in the floor.
We never assume it though. It takes a couple of minutes to check on the first visit, and it is worth checking before you set a budget in your head.
Will my basement need underpinning?
Probably not, and that is genuinely good news. Most Maple builds already have the ceiling height, so lowering the floor never enters the conversation. That is a real advantage over the older parts of the GTA where we run into it regularly.
Homes near the old village core are the exception and occasionally do need it. Where they do, benching or underpinning adds roughly $50,000 to $80,000 or more, so it is worth measuring before you fall for a design.
Who issues the building permit?
The City of Vaughan. Maple is part of Vaughan, so permits, inspections and any second suite approval go through them rather than Toronto or York Region.
We pull the permit in our name and handle the inspections, so nobody from the city is calling you.
Can I put a legal apartment in my Maple basement?
Often yes, and Maple homes tend to be good candidates because the ceiling height is usually already there.
You still need egress windows in every bedroom, fire separation between the suite and the rest of the house, interconnected smoke alarms, its own entrance, and zoning and parking that allow a second unit at your address. We confirm all of that with Vaughan before we draw anything, because there is no point designing a suite your house cannot legally hold.
Do I need a permit just to finish the basement?
For almost anything past paint and flooring, yes. Framing new walls, adding a bathroom, changing electrical, cutting in a new window or door, and any second suite all need a permit from Vaughan.
We take care of the filing and the inspections as part of the job.
My basement has been damp. Can it still be finished?
Usually, but not until the water is dealt with first. Depending on what is causing it, that might be regrading outside, repairing or adding weeping tile, putting in a sump pump, or waterproofing from the inside.
We know it is not what anyone wants to hear. It is also far cheaper than pulling finished walls apart in three years, which is a call we get more often than we would like.
How long does a basement take?
A rec room with no bathroom takes four to six weeks. Add a bathroom and it is six to ten. A legal second suite runs ten to sixteen weeks. Underpinning, if you need it, adds another four to eight on top.
Design and the Vaughan permit review happen before any of that. We build that window into the schedule from the start rather than letting you discover it after demolition.
Is a finished basement worth the money?
At resale you generally get back around 70 to 75 percent of what you spend. A legal suite is the stronger case, because it pays you rent while you live there and gives a buyer a documented income stream when you sell.
The one thing to watch is over improving for the street you are on. That matters more downstairs than anywhere else in the house, and we will tell you if we think you are heading that way.
Can we stay in the house while you work?
Almost everyone does. The work stays on one level, we seal off the stairwell, protect the route in and out, and clean up at the end of each day.
The noisy stretch is the concrete work if your basement needs a drain. It is loud while it lasts, but it does not last long.
