Why CNB in Scarborough

One crew. Fixed price.
Permits sorted.

Scarborough permits go through the Scarborough Civic Centre at 150 Borough Drive. CNB is familiar with local plan examiners and typical comment cycles for the area, and factors the review into your project schedule from day one.

Scarborough permit — filed

BCin designer submits at 150 Borough Drive. We track comments, respond and schedule all inspections. Included in your project price.

Strong rental demand

Scarborough's larger lots and steady tenant demand make it one of the GTA's most popular areas for a legal second suite. We build it to code, ready to rent.

WSIB + $2M liability

One crew — start to finish

Same in-house team handles framing, electrical rough-in, plumbing, tile and all finish work — the crew that starts your project is the crew that finishes it.

What we build in Scarborough

Basement renovation —
everything in-house.

Larger detached homes built 1970s–1990s, many with 7'–8' basement ceilings already compliant without underpinning. Strong secondary suite conversion rates — lowest cost-per-sqft in the GTA.

Full Basement Finish

Framing, insulation, drywall, LVP flooring, pot lights, trim — done by one in-house Scarborough crew, start to finish.

Legal Second Suite

Scarborough is zoned for secondary suites. Full kitchen, bath, egress window, fire-rated separation — delivered legal and rent-ready.

Walkout / Separate Entrance

West Hill and Guildwood's ravine lots often allow a full walkout — no excavation required. Side or rear entry on flat lots. Permit included.

Bathroom Addition

3-piece below grade. Ejector pump, tile, City rough-in and final inspection. Common upgrade in Scarborough basement suites.

FAQ · Scarborough

Questions about basement
renovation in Scarborough.

Can I build a basement apartment in Scarborough?

Yes. All Scarborough properties are zoned to allow secondary suites under the City of Toronto's Official Plan. CNB verifies zoning, files permits and delivers a legal, registered unit.

What goes into a Scarborough basement renovation?

A basic finish covers framing, insulation, drywall, flooring and trim. A full legal suite adds a kitchen, bathroom, egress window and separate entrance. We walk your space and give you a written scope and price before we start.

What does the timeline look like?

It runs in two parts: the City permit review at Scarborough Civic Centre, then the build. We give you a firm schedule upfront and keep you posted at every stage.

Is Scarborough a good area for a basement suite?

Yes — larger lots, strong tenant demand and as-of-right secondary-suite zoning make it one of the most popular areas in the GTA for a legal rental unit.

Do you serve all Scarborough neighbourhoods?

Yes — Agincourt, Guildwood, Morningside, Wexford, Birchcliffe-Cliffside, Malvern, Rouge and West Hill. Same crew, same written-scope guarantee.
