Standard construction contracts: the CCDC forms and what any contract must cover

Who writes the standard forms

The Canadian Construction Documents Committee, CCDC for short, is a national joint committee that, in its own words, "develops, produces, and reviews standard construction contracts, forms and guides." It was formed in 1974. Its members are two owner representatives each from the public and private sectors, the Association of Consulting Engineering Companies Canada, the Canadian Construction Association, Construction Specifications Canada and the Royal Architectural Institute of Canada. The Canadian Bar Association's construction law section sits as an ex officio lawyer member.

The committee says a document is ratified only after full consensus among its members. That is the reason lawyers, lenders and insurers across Canada know these forms: groups that speak for owners and groups that speak for contractors agreed the standard clauses before anyone signs them. A homeowner in Vancouver or Surrey who is handed a CCDC form can read its standard clauses as a starting point both sides accepted.

The forms are bought from the CCDC. Its page for CCDC 3 notes that the cost plus form is available in electronic format only. CCDC 41, the insurance requirements document, is free to download.

The main forms, by how the price is set

Each CCDC contract answers one question first: how will the contractor be paid? The table lists the forms a homeowner or small developer is most likely to meet, with the edition years shown on the CCDC documents page on 24 October 2026. The 2010 editions of CCDC 5A and 5B are still listed beside the 2025 editions, so check which edition a draft uses.

CCDC 2 2020 is the stipulated price contract, which the CCDC calls "the industry standard prime contract between Owner and prime Contractor." It sets "a single, pre-determined fixed price, or lump sum," and covers the consultant's role and authority, changes, work by other contractors, insurance, the conditions for the owner to take over the building, dispute resolution and early occupancy by the owner. It assumes monthly progress payments and refers to provincial payment laws where they apply.

CCDC 3 2016 is the cost plus version of the prime contract, and the cost plus fees chapter covers how its fee works. CCDC 4 2023 is a unit price contract, which pays an agreed rate for each measured quantity of work.

The two construction management forms suit a different set-up. In CCDC 5A 2025, the construction manager "acts as a limited agent of the Owner providing advisory services" and administers the contracts between the owner and the trade contractors, so the owner signs with each trade. In CCDC 5B 2025, the construction manager advises before construction and then performs the work, at actual cost plus a percentage or fixed fee, with options for a guaranteed maximum price or conversion to a stipulated price. CCDC 17 is the fixed price form for trade contractors on construction management projects.

Does a CCDC form fit a house or a multiplex?

The CCDC documents page lists no form written for a homeowner's own house or renovation. The prime contracts are built around a consultant, such as an architect or engineer, whose role and authority CCDC 2 sets out. A custom home or a fourplex in Vancouver may have an architect who can fill that role. A smaller renovation may have no consultant at all.

That gap has a legal effect in British Columbia. Under section 7 (1) of the Builders Lien Act, the payment certifier is the architect, engineer or other person the contract names as responsible for certifying payment. If the contract names no one, the owner acts as certifier for amounts owed to the contractor. A homeowner using a form that names a consultant who does not exist on the job takes on that role by default, and with it the duty to answer a request for a certificate of completion within 10 days.

So there are three common routes: a CCDC form with written amendments for the project, the builder's own contract, or a form from another source. Each can work. The test is the same in every case: does the document answer the questions below in plain terms, and does it match how this project will actually run? If a standard form is amended, the amendments hold the real terms. Ask for a copy that shows every change against the standard text, and read those pages first.

The clauses to check in any construction contract

Whatever the form, read the contract against this list. Each item is covered in more depth in another chapter of this guide.

Parties and licence. The contract should name the builder's legal entity exactly as registered and, for a new home, its residential builder licence. BC Housing states that general contractors, developers and building envelope renovators who build new homes must be licensed residential builders and must renew the licence every year.

Scope. The work should be defined by a numbered list of drawings, specifications and any written scope, each with its date or revision. Work outside those documents is a change.

Price and payment. The price basis, the payment schedule, the documents attached to each payment request, and how the 10% holdback under the Builders Lien Act is kept and released.

Changes. Who can ask for a change, how it is priced, and the rule that no extra is paid without a signed change order.

Time. A start date, a completion date or number of working days, the events that extend time, and what happens if the date is missed.

Insurance and safety. Which party buys property insurance on the work and which buys liability insurance, with limits and deductibles, and which party is the prime contractor for WorkSafeBC. Under section 13 of the Workers Compensation Act, the owner is the prime contractor unless a written agreement names someone else.

Completion and warranty. What counts as complete, how the deficiency list is handled, and, for a new home, the home warranty provider.

Disputes and ending. The steps for a disagreement, such as notice, meeting, mediation, arbitration or court, and the termination clause, which says when each side may end the contract and what is paid when it does.

When a lawyer should read it

This guide is general information about how contracts and BC statutes work. For advice on your own contract, have a lawyer who practises construction law read it before you sign in any of these cases: the price is large for your savings or borrowing, the contract is the builder's own form, a standard form has been amended, the contract has an arbitration clause, a lender is involved, or the project is a multiplex that will be sold or rented.

Bring the full set of documents to the review: the contract, every schedule and drawing list it refers to, the insurance certificates and the builder's licence details. And watch for one clause in particular. Section 42 (2) of the Builders Lien Act makes void any agreement that the Act will not apply or that its remedies will not be available. A clause like that has no effect, and its presence in a draft is a reason to ask the builder why it is there.
