Key takeaways
  • Whether a builder can raise the price after signing depends mainly on the wording of your contract and general contract law.
  • If you bought a new condominium unit from a developer, you may have a 10-day right to rescind and to get all your money back within 15 days.
  • Any waiver of your rights under the Condominium Property Act is void, and your remedies under it are in addition to other remedies.

The builder calls or emails to say lumber, labour or materials have cost more than expected, and the price in your signed contract now has to go up. It is stressful, especially if you have paid a deposit, sold your current home or lined up financing around the original number.

A signed contract is not automatically fixed in stone, and it is not automatically open to change either. This article explains how to approach the question, what protections exist if you bought a new condominium, and what to do before you agree to pay more.

This article covers the law of Alberta.

It usually comes down to your contract

For a house or other freehold home, the question of whether a builder can raise the price after signing is generally answered by the contract itself and by ordinary contract law. The reason the builder gives for the increase is only part of the picture. What your agreement says about price changes, and how it says they must be made, matters just as much.

Because the outcome turns on the exact wording, two buyers who were both told the same thing can end up in very different positions. A lawyer can read your agreement and tell you whether the clause the builder is relying on actually does what the builder says.

What to look for in an escalation clause

An escalation clause (sometimes called a price adjustment clause) lets the price change under stated conditions. Read it slowly and compare it to what the builder is now asking for.

If the clause is vague, one-sided or missing, do not assume the builder is right and do not assume you are right. Ask for the builder's position in writing and get advice before you sign anything new.

If you bought a new condominium unit

New condominium purchases from a developer have extra statutory protection under the Condominium Property Act. A developer must not sell or agree to sell a unit or proposed unit unless the required disclosure documents have been delivered to the purchaser. The purchase agreement must also include notice of your right to rescind within 10 days.

You can rescind by written notice to the developer within 10 days of the later of receiving the required documents or signing the agreement, and the developer must return all money paid within 15 days of receiving your notice. A developer or trustee must hold your money in trust until title issues.

Whether a particular price change counts as a material change, and whether your 10-day window is still open, depends on your documents and dates. Check them promptly with a lawyer.

Other things worth checking while you decide

A price dispute can distract from the basics. Confirm that your builder is licensed by searching the Builder Registry, which shows licence status and class, enforcement actions under the Act and homes built since February 1, 2014. A builder who does not appear there is not shown as licensed.

Also confirm the warranty. Builders must make sure the home is enrolled with a warranty provider and that the home under warranty is registered. You can search the Property Registry by civic address, lot/block/plan or builder to see whether the home has coverage and when it started.

What to do next

Frequently asked questions

Can a builder raise the price just because costs went up?

The reason the builder gives is not the whole answer. Whether an increase is allowed depends on what your contract says and on general contract law, so the exact clause matters. A lawyer can tell you whether the builder has a valid basis.

Can I cancel and get my deposit back if the builder raises the price?

It depends on your contract. If you bought a new condominium unit, you may rescind by written notice within 10 days of the later of receiving the required documents or signing, and the developer must return all money paid within 15 days of the notice. Outside that window, your rights turn on the contract terms.

Is my deposit safe while the building is not finished?

For a new condominium unit, a developer or trustee must hold your money in trust until title issues and deposit it into a trust account within 3 days of receipt, excluding holidays and Saturdays. For other homes, check what your contract says about who holds the deposit.

Can I waive my condominium rights if the developer asks me to?

Any waiver or release by a purchaser of the rights, benefits or protections under the Condominium Property Act is void. Be cautious about signing any document that says you give them up, and get advice first.
