Holdbacks and Builders' Liens in Nova Scotia: What Landowners Need to Know

If you own land in Nova Scotia and are developing it into rental housing, two features of provincial construction law will shape how money moves through your project: the holdback and the builders' lien. They exist to protect the people who do the work — and, handled correctly, they protect you, the owner, from paying twice for the same job.

This is not optional fine print. The rules sit in the Builders' Lien Act (RSNS 1989, c. 277) and its regulations [1][2]. Getting them wrong can freeze the title to your land, stall a construction draw, and turn a delivered building into a legal dispute. This article explains how the holdback and lien regime works in 2026, what your obligations are as the owner, and how the structure of your project affects your exposure.

A note on our perspective: Helio is a computation-driven real estate development company in Halifax. We do not act as your lawyer, and nothing here is legal advice — lien matters are technical and time-sensitive, and you should retain a Nova Scotia construction lawyer for any specific project. What we do is develop projects end-to-end on land our clients own, which means we live inside this framework on every file.

What a holdback is, and why the law requires it

A holdback is money the Builders' Lien Act requires you to withhold from each payment you make up the construction chain. Under Section 13(2), every person who is liable on a contract must "deduct from any payments to be made by him in respect of the contract, and retain for a period of sixty days after the contract is substantially performed, ten per cent of the value of the work, service and materials actually done, placed or furnished" [1].

So the figure is 10%, and it is calculated on the value of the work as it is performed — not on a single lump sum at the end. The retained amount forms what is informally called the lien fund: a pool that unpaid subcontractors, suppliers, and workers can look to if the contractor above them fails to pay them [2].

The point of the holdback is to break a problem that is otherwise structural in construction. You pay your general contractor; the general contractor is supposed to pay the subtrades; the subtrades are supposed to pay their suppliers and labourers. If a link in that chain fails — a contractor takes your payment but doesn't pass it down — the unpaid party can place a lien on your land, even though you already paid in good faith. The holdback caps that exposure: by retaining 10%, you preserve a fund that satisfies downstream claims without forcing you to pay the same work twice.

When the holdback can be released

The 10% must be retained for 60 days after the contract is "substantially performed." Under Nova Scotia's framework, work is substantially performed when two tests are met: the improvement is ready for use (or is being used) for its intended purpose, and the work still outstanding could be finished for no more than 2.5% of the contract price [2]. In plainer terms, the building is essentially done.

Section 13(6) allows the retained percentage to be validly paid out — discharging the liens it secures — once that 60-day period expires [1]. Practically, this means the date of substantial performance is a fact you need to pin down precisely, because the 60-day clock and your ability to release the holdback both run from it. If you carry a construction mortgage, your lawyer typically holds the holdback in trust and releases it only after confirming the period has run with no liens registered.

The trust-fund duty most owners overlook

Beyond the holdback, the Builders' Lien Act imposes a trust on money in the project. Under Section 44A, amounts an owner receives to finance the work constitute a trust fund for the benefit of the contractor; under Section 44B, amounts owing to or received by a contractor or subcontractor on account of the contract price constitute a trust fund for the benefit of those below them [1].

The consequence: a person holding those funds "shall not appropriate or convert any part of a fund to [their] own use or to any use inconsistent with the trust until the contractor is paid all amounts" owed for the work [1]. Misapplying construction funds is not merely a contract problem — it is a breach of a statutory trust, with personal-liability consequences for the people who direct the diversion. This is why disciplined draw management and clean accounting matter at every level of a development, not just at the top.

Builders' liens: how they arise and what they do to your land

A builders' lien is a charge registered against the title of the property where work was done. The parties who can claim one are broad: the general contractor, subcontractors and their subcontractors, material suppliers, labourers, and — where their work relates directly to the specific property — architects, engineers, and surveyors [2].

Once a lien is registered, it sits on the title for anyone to see, and it has real teeth. A property owner generally "cannot refinance or sell their property without first removing the lien" — typically by paying the claim or posting security to discharge it [2]. On a development file, that can also mean your lender refuses to advance the next construction draw until the title is clear, which is how a single unpaid subtrade can stall an entire project.

One nuance worth flagging early: liens may not attach to some government-owned property. If any part of the land you are improving is Crown- or municipally owned, get specific legal advice — the ordinary lien mechanics may not apply [2].

The two deadlines that decide everything

Builders' liens live and die on dates. There are two that matter, and both are unforgiving:

1. Register within 60 days. A claim of lien must be registered within 60 days after the last day work was done or the last materials were furnished or placed (Section 24) [1][2]. Miss it, and the lien right is gone.

1. Start a court action within 105 days. Under Section 26(1), a registered lien "shall absolutely cease to exist on the expiration of one hundred and five days after the work or service has been completed or materials have been furnished or placed" — unless in the meantime an action is commenced to realize the claim and a certificate (Form E) is registered in the registry [1].

Run the clock through an example. If the last day of work on a contract was January 15, the lien must be registered by roughly mid-March (60 days), and the court action started and the certificate registered by about April 30 (105 days from January 15) [1][2]. These periods cannot be extended, so anyone who needs to file — or anyone defending against an improperly filed lien — must move quickly and precisely.

For the owner, the takeaway is that your 60-day holdback period and the claimants' 60-day registration window are designed to overlap. If you have held the holdback correctly and the period passes with no liens registered, you can release the funds with the statute's protection. If a lien is registered, the retained holdback is the fund that most directly addresses it.

How project structure changes your exposure

The amount of lien and holdback management an owner carries depends heavily on how the project is organized.

The traditional approach is fragmented: the owner contracts a lead builder, who hires multiple subtrades, who hire their own suppliers and labourers. Every one of those parties is a potential lien claimant, and the owner is left tracking many separate pay chains, completion dates, and 60-day windows at once. The more independent parties touching the site, the more relationships in which a payment failure can ripple back to your title.

An integrated development model concentrates that responsibility. When planning, design, procurement, and construction oversight are coordinated through a single accountable party, the owner has one point of contact for payment status and one entity responsible for keeping the holdback and trust obligations correct across the chain. It does not eliminate the legal framework — the Builders' Lien Act applies to every project — but it reduces the number of fronts on which the owner is personally tracking deadlines and disbursements.

This is the part of the process Helio is built to carry. We compute the optimal development a given parcel can support — what the zoning, lot geometry, and servicing actually allow — and then develop it end-to-end on land the client owns, with construction delivered by established Nova Scotia builders. The holdback discipline, the draw schedule, the trust-fund accounting, and the lien-period tracking are managed as part of that coordinated process, with the owner's lawyer holding and releasing funds. The owner keeps ownership of the land and the finished building; we manage the machinery that keeps the construction money compliant.

We publish no construction price of our own — the cost of a given building depends on its design, location, and the market at the time. As a reference point, CMHC's Housing Design Catalogue (Halifax basis, Q1 2025) estimates hard construction cost for small multi-unit buildings at roughly $217,000–$387,000 per unit, a figure that includes the general contractor's overhead and profit but excludes land, financing, soft costs, and developer profit, and to which a 5–10% contingency should be added [3]. Those are CMHC's numbers, not ours, and they illustrate why a serious holdback strategy matters: the dollar amounts withheld and tracked on a multi-unit project are substantial.

Practical discipline for owners

Whether you run a project yourself or work through a development partner, a few habits keep you on the right side of the framework:

• Withhold the 10% on every payment, every time. It is a statutory obligation, not a negotiation point. Apply it as work is valued, not only at the end [1].
• Keep clean payment records. For each payment, record the date, the amount paid, the 10% retained, and the work it covered. If a lien is later registered, this is the evidence that you held the holdback and are not exposed beyond it.
• Pin down the substantial-performance date. Your 60-day holdback period runs from it, and so does much of the lien timing. Give your lawyer real dates, not estimates [1][2].
• Watch the whole chain, not just your direct contractor. Subtrades and suppliers you never contracted with can still register liens against your land [2].
• Retain a Nova Scotia construction lawyer for the holdback and any lien event. The deadlines are strict and the registry procedures technical; a missed step is expensive [2].

The bottom line

The holdback and the builders' lien are two halves of the same protective system. The 10% holdback, retained for 60 days after substantial performance and governed by a statutory trust, gives unpaid workers and suppliers a fund to claim against — and gives you a ceiling on the risk of paying twice [1][2]. The builders' lien, with its 60-day registration and 105-day action deadlines, is the enforcement mechanism that makes the system real, and the thing that can freeze your title if the money below you goes wrong [1][2].

For a landowner developing rental housing in HRM, the goal is not to memorize the statute — it is to build a project whose financial machinery is structured so these obligations are met cleanly, with experienced legal counsel on the holdback and a coordinated development process keeping the chain of payments accountable. Handled well, the framework is exactly what it was designed to be: protection, not a trap.
