You finished the job. You showed up every day, supplied the materials, and delivered what was promised. But what if the payment doesn’t come?
In British Columbia, you have a powerful tool to protect yourself: the builders’ lien. But that tool has a hard deadline of 45 days. Miss it, and your claim is gone. No extensions. No exceptions. No coming back.
Here’s everything you need to know about filing a builders’ lien in BC, the deadlines that control your rights, and the mistakes that could cost you the money you’re owed.
Why Builders’ Liens Demand Precision
Construction projects involve multiple parties, tight schedules, and substantial financial commitments. When payment disputes arise, construction liens provide an important legal remedy. However, the protections offered by the British Columbia Builders Lien Act are only available to those who follow the statutory requirements carefully.
A builders’ lien is a registered legal claim against a property title. Filing one correctly can stop a sale, block financing, and give you real leverage to recover what you’re owed. Filing one incorrectly can get it rejected before it even gets off the ground.
How the Builders’ Lien Act Protects Unpaid Contractors and Suppliers
Construction runs on a chain of trust. An owner hires a general contractor, who hires subcontractors, who hire workers and order materials. When payment stops at any level, everyone downstream gets hurt.
The Builders’ Lien Act addresses this by giving anyone who contributes work or materials the right to register a claim against the land they improved. A properly registered lien attaches to the title and must be dealt with before the property can be sold or refinanced. In extreme cases, courts can order the sale of the property to satisfy lien claims. For subcontractors and suppliers without direct contracts, this statutory right is often the only real leverage they have.
Who Can File a Builders’ Lien in BC?
Contractors, Subcontractors, and Suppliers
If you provided work or materials that improved a property, you’re likely eligible.
This includes:
- General contractors, when owners withhold final payment or dispute extras.
- Subcontractors of every trade, like framers, electricians, plumbers, drywallers, and roofers.
- Material suppliers, such as lumber yards, concrete plants, and tile stores.
- Equipment rental companies.
Small trades and sole proprietors who can’t afford to carry unpaid invoices are also covered.
Workers, Architects, and Engineers
Individual workers can actually file liens for unpaid wages. Architects and engineers can also file, but only for work directly tied to the physical improvement of a property. Design-only services that never translate to on-site construction generally do not qualify.
Notably, you cannot file a builders’ lien against federal government property, public highways, or certain Crown bodies, though holdback obligations still apply on those projects.
Understanding the 45-Day Builders’ Lien Deadline
The 45-day filing deadline is arguably the most important rule under the Builders’ Act. Missing it can eliminate otherwise valid lien rights.
What Triggers the 45-Day Clock?
The clock starts from the first of these events to occur:
- The issuance of a certificate of completion
- Substantial completion of the improvement
- Abandonment of the project
- Termination of the contract, even if the project isn’t finished. This catches many subcontractors off guard. The moment your contract ends, however it ends, your deadline begins running.
If you’re unsure whether the clock has started, treat it as if it has. You can always withdraw a lien; you cannot recover one filed too late.
What Counts as Project Completion?
“Substantially complete” typically means the improvement is 95–98% finished and can be used for its intended purpose, even if minor deficiencies remain. The issuance of a Certificate of Completion or the reaching of substantial performance under the contract triggers the deadline.
Common Mistakes That Can Invalidate a Builders’ Lien
A lien claim that is filed but defective is almost worse than no lien at all. It gives a false sense of security while leaving your claim exposed.
Filing the Lien Too Late
This is the most frequent mistake, and the most consequential one. There is no grace period, no application to extend, and no remedy once the deadline passes. If you’re uncertain when your 45 days started, count from the most conservative date and file immediately.
Naming the Wrong Owner or Property
Your lien must correctly identify the registered owner of the property and provide an accurate legal description.
The property owner shown on the title at the Land Title Office is the party your lien is filed against. Using a trade name, a nickname, or an outdated ownership record can result in the lien being struck.
You can find the current registered owner and the Parcel Identifier (PID) through the BC Assessment website or directly via the Land Title and Survey Authority (LTSA).
Errors in the Claim of Lien Form
The official Form 5 (Claim of Lien) must be completed accurately. Common errors include overstating the amount owed, providing a vague description of work, or failing to identify who hired you.
Under section 45 of the Act, filing a claim with false or inflated information can result in fines up to $2,000 or the amount over-claimed, whichever is greater.
Filing in the Wrong Land Title Office
BC has multiple Land Title Office districts. Your lien must be filed in the office that serves the district where the property is located, not simply the one closest to you. Filing in the wrong district means your lien will not appear on the property title and offers no protection at all.
Missing the One-Year Enforcement Deadline
Filing the lien is only the first step. Once registered, you have 180 days to commence a legal action to enforce it, typically a Notice of Civil Claim filed in BC Supreme Court. If that deadline is missed, the property owner can have the lien cancelled by the Registrar of Land Titles.
This 180-day enforcement window is separate from the two-year statute of limitations in BC under the Limitation Act. Do not confuse them.
Improper Notice and Service Requirements
After registration, a copy of the lien should be served on the property owner and on the head contractor if you are a subcontractor.
Courts expect prompt service, and failure to notify the relevant parties can create complications when you later try to enforce. While the Act does not prescribe a specific service deadline, unreasonable delay can be used against you.
Confusing Lien Deadlines With Limitation Periods
Many contractors confuse builders’ lien deadlines with the broader statute of limitations in BC rules. These are separate legal concepts.
The Builders Lien Act establishes specific filing and enforcement deadlines for lien claims. Meanwhile, the Limitation Act governs the time limits for many civil lawsuits.
A contractor may lose lien rights under the BC lien act while still retaining a separate breach-of-contract claim. However, losing lien rights often means losing one of the strongest collection tools available.
Holdback Rules Under the Builders’ Lien Act
The holdback system is one of the most misunderstood, and most consequential, features of the Act.
Owners are required to retain 10% of every payment made during construction. This fund sits as security for lien claims. Contractors hold equivalent obligations toward their subcontractors.
Why does this matter in practice? Two scenarios:
- Owner releases holdback too early. If a subcontractor later files a valid lien, the owner may owe that amount out of pocket, even if they’ve already paid their general contractor in full.
- Contractor doesn’t understand when holdback releases. Holdback generally cannot be released until the 45-day lien period has passed without a claim being filed. Releasing early exposes the contractor to liability.
Because holdback requirements vary depending on contract type and project stage, careful compliance at every payment milestone is essential.
Builders’ Liens on Residential and Commercial Projects
The filing mechanics are the same whether you’re working on a residential renovation or a commercial tower. The practical stakes are very different.
Residential: Property owners are often individuals who paid their general contractor in full and are blindsided by a lien from a subcontractor they’ve never met. Their exposure depends entirely on whether they retained the required holdback. If they didn’t, they may owe the subcontractor directly, out of their own pocket, on top of what they already paid.
Commercial: Developers and sophisticated owners move quickly, disputing liens, posting bonds, or paying into court. Subcontractors on large commercial projects often face well-funded opponents who know the Act as well as any lawyer. Filing a technically sound lien is the baseline; knowing how to enforce it under pressure is what counts.
What Happens After a Builders’ Lien Is Filed?
Once your lien is registered, it appears on the property title within hours and immediately restricts the owner’s ability to sell or refinance. That pressure is often enough to bring parties back to the table.
Starting a Lien Enforcement Action
If the dispute is not resolved through negotiation, you must file a court action within 180 days of registering your lien.
Most actions are started in the BC Supreme Court as a Notice of Civil Claim. The majority of contested lien matters settle before trial once it becomes clear that the lien is properly registered and the claimant is serious about enforcement.
Removing a Lien by Bond or Payment Into Court
An owner or contractor who wants to clear a lien from title without paying the claimant immediately can apply to have it replaced by a lien bond or a payment into court.
This removes the encumbrance from the property, allowing a sale or financing to proceed, while preserving the claimant’s rights against the substitute security.
The bond or court payment must equal the full amount of the lien claim. From the claimant’s perspective, this is not a loss; the security has simply changed form.
Priority of Competing Lien Claims
When multiple lien claimants file against the same property, they generally share in the holdback funds on a pro-rata basis. If holdback funds are insufficient to cover all claims, the court may order the sale of the property and determine the priority and distribution of proceeds.
The order in which liens and mortgages rank can be complex, particularly on projects where a construction mortgage was advanced in stages. Getting this analysis right requires experienced construction litigation counsel.

Frequently Asked Questions About Builders’ Liens in BC
Can I File a Builders’ Lien After 45 Days?
No. Once the 45-day window passes, your lien right is extinguished. A breach-of-contract claim may still be available under BC’s two-year limitation period, but the ability to register a charge against the property is gone.
Does Warranty or Deficiency Work Extend the Deadline?
Generally, no. Courts in BC have consistently held that warranty work or deficiency repairs performed after substantial completion do not restart or extend the 45-day clock.
The question is whether the work constituted a genuine contribution to the improvement or simply remedial work under a warranty obligation. If there is any doubt, treat the deadline as running from the original substantial completion date and seek legal advice immediately.
What Happens if Multiple Properties Are Involved?
If your work contributed to more than one property, for example, on a subdivision or a multi-lot development, you must apportion the amount of your lien claim between the properties.
You cannot file a single lien for the full amount against one property if your work benefited several. Apportionment errors can result in a lien being reduced or struck entirely.
Can You File a Lien Against a Strata or Leasehold Property?
Yes, with some nuances. For strata properties, the lien generally attaches to the specific strata lot where the work was performed, not the entire strata corporation. For leasehold properties, your lien may attach to the leasehold interest rather than the freehold title.
What Is the Difference Between a Builders’ Lien and a Trust Claim?
A builders’ lien is a claim registered against a specific property. A trust claim is a personal claim against the party that received and misappropriated construction trust funds. Both protections exist under the Builders’ Lien Act, but they operate differently.
Trust claims are particularly powerful because they can extend to directors of incorporated companies personally, and they can survive the insolvency of the company that received the funds.
If the company that owes you money has gone bankrupt, a trust claim may offer recovery where a lien cannot. Both strategies are often pursued together for maximum protection. For more on related disputes, see also construction litigation in BC and commercial litigation.
