Selling a Calgary house when the foundation has problems

You can sell a Calgary house with a cracked or settling foundation, and nothing in Alberta law stops you. What changes is what you owe the buyer in writing, which turns on whether the house is young enough to still carry its new home warranty, and on whether any repair already done to it was permitted.

This is written for the owner looking at a stair-step crack in the basement wall, a door that will not latch any more, or an engineer's report somebody left in a drawer. If the work is more than you want to take on, the way we buy houses that need repairs is the part of our side that applies.

A cracked foundation does not stop the sale, it changes what goes in writing

Alberta keys the duty to the kind of defect, not to a form. The Real Estate Act Rules define a material latent defect as one a reasonable inspection of the property would not turn up, and include a defect that makes the property "dangerous or potentially dangerous to the occupants" or "unfit for habitation". The Real Estate Council of Alberta puts the same test in plainer words in its information bulletin on material latent defects, last revised in April 2014. A latent defect is "a defect that cannot be discovered with reasonable care during an inspection", and a material defect is "a defect that reasonable people would agree is significant" in the particular circumstances of the transaction.

What a foundation triggers on RECA's list of defects that may also count is the money and the paperwork. A material latent defect may exist where "the defect is very expensive to repair", and where "the seller does not have appropriate building or other permits for the property".

The split that decides your own paperwork is between what a buyer can see and what they cannot. RECA's own due diligence checklist for licensees representing sellers tells the agent, on patent defects, to "Advise seller there is no legal obligation to disclose this information", and on material latent defects to "Advise seller there is legal obligation to disclose this information", and to "Have seller acknowledge in writing if he/she is aware of any material latent defects." What the contract itself still carries no matter what you say out loud is set out in what you have to disclose when selling a house in Alberta. Where your own house falls is a question for your own lawyer.

If the building permit was applied for after February 2014, check the warranty first

This is the check almost nobody does, and it is free. Alberta's New Home Buyer Protection Act sets minimum warranty coverage on new homes in four tiers, and the Government of Alberta's new home warranty overview lists them as one year for labour and materials, two years for delivery and distribution systems, five years for building envelope protection, and "10 years for major structural components". Then it says exactly what that last tier covers: "Major structural consists of the frame, including the roof's structural integrity, and the foundation."

The part that matters to a seller is who owns that coverage. Alberta's wording is that "A new home warranty is attached to the home, not the owner of the home, and remains in effect upon the re-sale of the home" until the coverage expires. You do not have to be the original buyer to be inside it.

The conditions on it are strict. The Act reaches homes whose building permit was applied for "on or after February 1, 2014", which is a permit application test rather than a build year, so a house finished in 2015 on a permit applied for in 2013 is outside it. And the clock does not start when you bought the house: coverage begins at the first of the home being occupied, the permitting authority granting permission to occupy, or title transferring to the owner. A resale buyer inherits the remainder, not a fresh ten years.

You can check a specific address yourself. Alberta runs a public property registry under its Residential Protection Program, described by the government as an online source of information about warranty coverage, or the appropriate warranty exemption, for homes built in Alberta since February 1, 2014, and it searches by plain civic address. The coverage limit for a single family home is set at "a minimum of $265,000". If your permit predates February 2014, and most Calgary houses with settling foundations do, there is nothing here for you, and it is worth five minutes to find that out rather than assume it.

Repairing it is permitted work, and the missing permit is what follows the house

The City of Calgary's list of projects that require a building permit includes "Repairs or alterations to existing buildings and structures", and foundation work is such a repair. The City does not print the words underpinning or piling in that list, so take the general wording at face value and ask rather than assume: the City's own instruction on its structural repair requirement lists is "For confirmation, contact the plans examiner."

An engineer is usually in it. The City says "Engineering may be required for structural alterations", and where it is, the drawings carry the seal of an engineer "registered to practice in the province of Alberta", who "should be registered with APEGA". Fees are modest next to the work itself. No fee row on the City's schedule names foundation repair, and the residential alterations row showed a total of $205.92 when we checked, on a page that prints no revision date. Its residential improvement permits carry a 7 calendar day target for low complexity and 21 days for high complexity, and between April and June 2026 it reported averages of 10 and 15 days.

Now the part the rest of the internet leaves out. The City keeps the permit history, and a buyer can pull it: its page on buying and selling a property sends owners to myProperty "to see the permit history for the last 10 years for residential properties." If the work was never permitted, the City says "Work previously completed without permits can be inspected by The City", that the proper permits have to be obtained first, and that "During the framing inspection, portions of the drywall may need to be removed to expose the work that was done." It lists the consequences of leaving it, among them "Future legal and financial issues when selling your property or making an insurance claim", and it closes the obvious excuse by noting the duty holds "even if you hired a contractor who assured you permits were not needed." Its blunt sentence is the one to keep: "Ultimately the homeowner is responsible for any previous concealed work." The City publishes no figure for the fine, and we could not find one.

Put that beside the Rules and the shape of the problem changes. A repaired foundation with a permit behind it is a repaired foundation. The same repair with no permit is a condition that "a lack of appropriate municipal building and other permits respecting the real estate" may make disclosable in its own right, on top of the crack.

Listing it as is, repairing it first, or selling to a direct buyer

Listing it on the open market will beat any direct offer including ours, and the gap is widest on a house in good shape. The thing to plan for is the inspection. A foundation issue surfaces there rather than at the showing, so budget for a renegotiation partway through a deal you thought was done, and expect the buyer's lender and appraiser to take an interest in a way they do not on a tidy house. We found no Alberta source publishing a lending rule for this, so ask the question of the buyer's lender rather than guessing at it.

Repairing first and then listing is the route that pays back best and costs the most up front. It means an engineer, a permit, a contractor, a City inspection and the whole bill settled out of your own pocket before the sale funds anything, and the paperwork it generates is exactly what makes the house easy to sell afterwards. If you have the money and the months, this is the strongest option, and it is the one we would point you to first.

Selling to a direct buyer is narrow, and here is where it is wrong for you. If the house is in good condition and you are not in a hurry, we are the wrong call. We will not help you keep a known defect off the paperwork, we will not take on an unpermitted repair as though it never happened, and a seller who can afford the repair and wait for the market will do better listing.

Where it earns its place is a foundation you have been quoted on and do not want to finance, an inherited or empty house you are not going to renovate, or a date you need certainty around. How we buy takes out the showings, the staging and the repair list, and runs as little as seven to ten days with two to three weeks more usual, and what we pay is written out rather than implied. Here is a Calgary house we bought as is. As Matthew puts it: "If your house is in good to great condition and you're not in a hurry, listing with a Realtor may be a better option, and I'll tell you so to your face."

What a Certificate of Compliance and a Real Property Report do not cover

A buyer's lawyer or lender will usually ask for both documents, and sellers read them as a clean bill of health, which neither one is. The City describes a Certificate of Compliance as "a confirmation from The City of Calgary that the locations of structures on a property comply with the Land Use Bylaw", and then says plainly that it "does not regulate or enforce any building code requirements", and that it is no confirmation of a property's permit history. It goes further: "Permits are not reviewed as part of the Certificate of Compliance", and "The Certificate of Compliance only relates to the building(s) location." The City also notes it "is not a legislative requirement", though lenders and lawyers commonly want one anyway.

The Real Property Report has the same narrow job. RECA's bulletin describes it as a legal document prepared by an Alberta Land Surveyor that illustrates "property boundaries and improvements (structures) relative to the boundaries", and the Alberta Land Surveyors' Association says a report "doesn't expire, but it becomes outdated if new improvements are added or changed". Nothing we could find from the City, from RECA or from the surveyors' association addresses whether repairing a foundation changes anything on a Real Property Report, and we would rather print that gap than fill it with a guess. A buyer can hold a current report with a compliance stamp on it and still know nothing about whether your foundation is sound or whether the repair was permitted, which is why the permit history and the engineer's report are the papers that actually move this sale. The same pattern runs through other condition problems, and the one Calgary houses hit most often is set out in selling a house with poly-B plumbing.

Before you talk to anybody, gather the address and the year the house was built, any engineer's report, quote or invoice for work already done, and the permit history from myProperty. With those in hand a Realtor can price a listing properly and we can read the house honestly, and you can write to us if you want that read before you decide.
