$2,500 off your basement

Taken straight off the price when you sign. It is not a payment plan and we do not offer financing. The audit, the design and the quote cost you nothing either way.

What the audit actually is

Every contractor in Calgary offers a free quote, so a free quote is not worth much. This is a named piece of work with something at the end of it, and it is yours whether or not you hire us.

We measure

Finished ceiling height, the foundation walls, where ductwork and services run, and where a compliant EGRESS WINDOW could go.

We tell you straight

What your basement will take and what it will not. If a legal suite does not work on your property, we say so.

Free 2D structure design

A drawn layout of your actual basement, not a stock plan. This is what makes a quote mean something.

Fixed written quote

Every line itemised, permits stated, allowances given a real value. Then $2,500 comes off if you go ahead.

What we check while we are there

These decide what is possible downstairs. Most of them cannot be judged from a photograph, which is why somebody has to stand in the room.

Basements we have already built

Every photograph on this page is our own work. 500+ projects over 20+ years, with a one-year workmanship warranty on all of it.

Questions people ask first

How does the $2,500 off work?

It comes straight off the price of the build when you sign. It is not a payment plan and we do not offer financing. The audit, the 2D structure design and the quote are free whether or not you go ahead.

Is the audit really free?

Yes. We measure the basement, tell you what it can take, and give you a 2D structure design and a fixed written quote. No charge and no obligation.

How long does it take?

Usually under an hour in the house. The 2D structure design and the written quote follow afterwards.

Can any basement become a legal suite?

No, and that is the honest answer. Ceiling height, the foundation walls, where services run and whether a compliant EGRESS WINDOW can be cut all decide it. Finding out is the point of the audit.

Do you handle the permits?

Yes. We apply for the building permit and the licensed trades pull their own. We manage the inspections through to registration with the City of Calgary.

What does a legal basement suite rent for in Calgary?

Through 2026 we see well finished legal suites rent broadly between $1,500 and $1,750 a month, varying with size, finish, separate entrance, parking and location. Treat that as a moving range and check current listings for your own area.

Is there any City funding?

The City of Calgary Secondary Suite Incentive Program offers up to $10,000, paid as a reimbursement after the suite is registered. It is waitlisted as of 24 June 2026, carries a two-year restriction on short-term rental use, applies to the main dwelling only, and the permit has to be in place before applying. Check the City website for current status.
