Prefab project formation in Nova Scotia: beyond the factory quote

A prefab factory quote is a price for a manufactured building. It is not a price for a project. Between the quote and an occupied building sit a dozen scopes that someone else supplies, prices and warrants: site investigation and servicing, foundations and a crane pad, transport and the permits to move oversized loads, the crane day, assembly and the stitching between modules, the mechanical and electrical interfaces, the code path and the inspections that close it, a payment profile that does not match a lender's draw schedule, and a warranty with a seam through the middle of it. This guide names each of those scopes for a volumetric modular or panelised multi-unit housing project in Nova Scotia, says who is ordinarily responsible for it, and is explicit about the places where the public record does not answer the question and the reader has to ask.

What a factory quote covers, and what it does not

A factory quote prices a manufactured building: modules or panels built to a specified design and delivered to a stated point. It is a real price for a real thing, and it is not the price of a project. Everything that has to happen before anyone can live in the building is bought separately, from different parties, on different schedules.

The scopes a quote ordinarily leaves outside are consistent enough to list:

  • site investigation, servicing and the grading design;
  • foundations, and the crane pad and access the set day needs;
  • transport, the permits to move oversized loads, and the crane day itself;
  • assembly and the stitching where modules meet each other, the foundation and the weather;
  • the mechanical, electrical and sprinkler interfaces between factory work and site work;
  • the building-code path, the certification the factory carries, and the on-site inspections that close the file;
  • insurance in transit and during the set, and the warranty covering each half afterwards.

There is no standard division of factory and site work to assume; it varies by manufacturer, by product and by contract. So the first document to ask for is not a price but a scope schedule: what is inside the module when it leaves the plant, what arrives loose for site installation, and what the manufacturer expects to find waiting when the trucks arrive. For scale on the rest, CMHC's Housing Design Catalogue estimated hard construction cost for small multi-unit buildings on a Halifax basis at roughly $217,000 to $387,000 per dwelling unit in Q1 2025, excluding land, financing, soft costs and profit. Those are figures for construction generally, not for a prefab delivery. The approach page frames the same boundary from the project side.

Site investigation, servicing, foundations and the crane pad

A module cannot be set on an idea of a foundation. Before anything is ordered, the site has to be investigated: geotechnical conditions under the building and under the crane, a survey, the capacity of water, sanitary, storm and electrical services at the street, and a grading design that works with the finished floor level the modules impose.

Foundations for a factory-built building are a precision item. The manufacturer sets the dimensional tolerance the foundation must meet, the foundation contractor has to build to it, and someone has to survey the finished foundation and confirm it before modules ship. Those tolerances belong to the manufacturer and appear in no public source, so get them in writing and hand them to the foundation contractor and the surveyor as a named deliverable with a date against it.

The crane pad and the approach are their own scope: bearing capacity under the crane's outriggers, a laydown area for modules waiting to be set, and roads the transporters can turn into. If a structure has to come down first, Halifax requires a separate demolition permit, currently $62.50 with engineering-related fees possible, under the municipal fee schedule effective 1 April 2024. Grading deserves early attention for a second reason: HRM will not issue an occupancy permit while a final lot-grading certificate is outstanding, which puts site drainage on the critical path rather than on the punch list.

Transport, the crane day and the stitching

Modules travel by road, and the road settles a great deal about the building. Dimensions against legal limits, the route survey, permits for oversized loads, escorts, timing restrictions, overhead structures and turns all constrain what can be made in a factory and delivered to this particular site. None of the sources cited in this guide document Nova Scotia's oversize-load permitting, escort requirements or road-closure rules for a crane day. That is a real gap, and it should be closed directly with the provincial road authority and the municipality before a delivery date is promised to a lender, a tenant or a board.

The crane day is the project's fixed point. A crane is booked, an assembly crew is booked, traffic control may be needed, and the cost runs whether or not the site is ready to receive. Settle in advance who holds the permits, who decides on weather, and who carries the cost of a lost day.

Then comes the stitching, which quotes are usually silent about. Modules are connected to one another and to the foundation; roof and wall closures are built at the joints; exterior finishes are completed over the seams; interior finishing is done at every interface. Mechanical, electrical and sprinkler work is the same story in miniature. Some of it is installed in the factory and terminates at a defined point, and someone else connects, tests and commissions it. Record where each service terminates, who connects it, and who signs the commissioning record.

The code path: Part 9, Part 3 and factory certification

The code path is set by size and occupancy, not by how the building is made. Under the National Building Code as adopted in Nova Scotia, a building may use the simpler Part 9 path only if it is three storeys or fewer in building height, has a building area of not more than 600 m² (about 6,460 sq ft), and is not an excluded major occupancy such as assembly, care or detention, or high-hazard industrial. Cross either threshold, or fall into an excluded occupancy, and it is a Part 3 building on a different engineering and review path. An eight-unit, three-storey low-rise inside 600 m² can hold a Part 9 path; a taller or larger stacked configuration will not.

Nova Scotia adopted the 2020 national building, energy and plumbing codes under N.S. Reg. 198/2024, in force 1 April 2025, phased in by tier: building code Tier 2 from 1 April 2026, energy code Tier 2 and building code Tier 3 from 1 April 2027, energy code Tier 3 from 1 April 2029. Section 9.36, as adopted in Nova Scotia, requires at least Tier 2 for climatic Zone 6 from 1 April 2026. Accessibility is a separate layer: the Built Environment Accessibility Standard Regulations apply to construction beginning on or after 1 April 2026 and exclude private residences of three dwelling units or fewer.

Factory certification is the item this guide cannot source. How a factory-built building is certified in Canada, and which certification a Nova Scotia authority accepts in place of inspections it would otherwise perform, is not documented in the material cited here. Ask the manufacturer which certification its plant and its product carry, and confirm acceptance with the municipality before an order is placed. The code is provincial, but permits and inspections are municipal, so process and fees vary.

Inspections, the occupancy permit and warranty

Certification in a factory does not remove the municipal file. In Halifax an occupancy permit is required before a building may be occupied, other than single dwellings, sheds and pools. It requires a valid building permit and a passed final inspection, and will not be issued while items such as a final lot-grading certificate are outstanding. What HRM inspects specifically on a factory-built building, such as foundation-to-module connections or the on-site electrical and mechanical stitching, and whether the sequence differs from a site-built equivalent, is not documented in these sources. Ask for the inspection sequence in writing early, not once the crane is booked.

Warranty is the other thing that does not arrive on the truck. Nova Scotia does not require a new-home warranty: neither legislation nor regulation obliges a developer of new condominiums to provide one, per CMHC's Nova Scotia fact sheet, so any coverage is discretionary. Where a warranty is procured, the conventional shape is roughly one to two years on materials and workmanship, about two years on water penetration and the envelope, and up to ten years on major structural defects. That is industry convention rather than Nova Scotia statute, and the certificate governs.

A prefab project has two warranties to obtain and one seam to define: what the manufacturer warrants on the module, what the site contractor warrants on foundations, servicing, assembly and stitching, and who answers for a defect that could plausibly belong to either. How that split is normally drawn is not documented in these sources, which is precisely why it should be drawn in the contract, along with the process for a defect neither party accepts.

Who is responsible for what

Prefab does not remove work. It moves work, and it changes who is holding each piece. A prefab-led project typically has at least five parties with distinct responsibilities: the manufacturer, for the building it fabricates and certifies; the site contractor, for foundations, servicing, assembly and finishing; specialist engineers, for the structural, geotechnical, mechanical and electrical design each is retained to produce; the owner, who sets the objectives, appoints the parties and retains the decisions assigned to it; and, on some projects, a coordinating party who holds the interfaces between them.

The interfaces are where projects fail, and each one has a name. Who sets the foundation tolerance and who verifies it. Who owns the transport route and its permits. Who carries the risk if a module is damaged in transit. Where the factory's mechanical and electrical work terminates, and who connects and commissions it. Who holds the building permit. Who calls the crane day. Who fixes a defect at the seam. Every one of those should have a party's name against it in writing before the order is placed.

Coordination of that kind is substantive work rather than a substitute for technical design, construction management or the owner's approvals. It is the role Helio takes under an agreed project mandate, with scope and authority settled before the work proceeds; the owner still decides, and construction is delivered by established builders and manufacturers appointed on the project. Where that role does not exist, it does not disappear. It lands on the owner by default, usually on the crane day.

The payment profile, holdbacks and financing

A factory is paid differently from a site contractor, and the difference reshapes when capital is needed. A manufacturer's deposits and fabrication milestones move money out before anything exists on the site. A construction lender advances in staged draws gated by an inspection confirming a defined on-site milestone, with the borrower generally funding a stage before the draw that reimburses it, and interest accruing only on what has been advanced. The two schedules do not align by themselves. Reconcile them before either is signed, and ask the lender in writing how it treats payments for goods not yet on the site.

The Builders' Lien Act adds structure of its own. The person primarily liable on a construction contract must retain 10% of the value of work, service and materials for 60 days after substantial performance, which the Act defines as the work being ready for use with the remainder completable for not more than 2.5% of the contract price. Financing an owner receives, and payments a contractor receives, are statutory trust funds under ss.44A and 44B. Whether the 10% attaches to a factory's invoices for off-site fabrication, or only to on-site work, is not settled in these sources. Put that question to counsel and to the lender together.

The far end is coupled too: the occupancy permit gates lawful occupation and therefore the take-out mortgage, and a condominium cannot be registered without proof of occupancy permits for every residential unit under the Condominium Regulations. On the program side, CMHC's Apartment Construction Loan Program lends from $1 million at up to 100% of residential loan-to-cost for projects of at least five rental units, on terms as at 6 November 2024. HST has been 14% since 1 April 2025, and the purpose-built rental rebate refunds 100% of the federal part to a maximum of $35,000 per qualifying unit, which matters because long-term residential rent is an exempt supply carrying no input tax credits. The calculators test the debt side of that at current published rates. How the whole funding plan fits together is the subject of the companion guide on funding a prefab-led project.

Schedule: factory lead time against site readiness

Two clocks run, and different people set them. The factory's clock is a production slot. Ask for it as a dated commitment, ask what holds it and what releases it, and note that no Nova Scotia-specific factory lead time appears in the sources cited here, so that number has to come from the manufacturer with a date attached.

The site's clock is entitlement and permitting, and it can be measured. Measured over HRM's own open building-permit and planning records through the Halifax Developments Map (source records: HRM open data) to June 2026, a new building permit for a building of five or more units took a median of about 11 weeks from application to issuance (n=259; 75th percentile about 20 weeks, 90th about 39 weeks), and a two-to-four-unit building about 3 weeks (n=449). Where a discretionary approval comes first, a development agreement took a median of about 366 days (n=110; 75th percentile about 528 days), and planning applications overall about 144 days (n=329). HRM has no statutory review deadline, so these are observed durations rather than commitments, and the recent cohort is right-censored, which understates the slowest waits.

Whether that discretionary step applies is the schedule question worth answering first. An as-of-right project proceeds on a development permit, a minor relaxation is a variance, and a larger departure needs a development agreement or rezoning approved by Council. HRM's June 2024 amendments permit up to eight dwelling units per lot as of right in the Regional Centre's ER-3 zone, lot-size dependent, with a maximum height of 11 metres and a minimum lot area of 325 m² for one to four units. That is one route to a site timeline predictable enough to hold a production slot against. The crane day is where both clocks must meet; most things can slip a week, and that cannot.

Checklist

How to form a prefab-led housing project

  1. Get the scope schedule before the price Ask the manufacturer, in writing, what is inside the module when it leaves the plant, what arrives loose for site installation, and what it expects to find waiting on site: foundation tolerance, access, laydown, services and a set date. There is no standard factory/site split to assume, so treat this document as the basis of every other scope.
  2. Fix the code path before design is ordered Establish whether the building sits under Part 9 (three storeys or fewer, building area not more than 600 m2, not an excluded occupancy) or Part 3, and which code and energy tier applies on the intended construction start date. Ask which certification the plant and product carry, and confirm with the municipality that it accepts it.
  3. Investigate the site and the route together Commission geotechnical work, a survey, a servicing capacity check and a grading design, and at the same time survey the transport route and crane access. Confirm oversize-load permits, escorts and any road closure with the provincial road authority and the municipality before a delivery date is promised to anyone.
  4. Name a responsible party for every interface Write down who sets and verifies the foundation tolerance, who holds the transport permits, who carries transit damage, where each mechanical and electrical service terminates, who connects and commissions it, who holds the building permit, who calls the crane day, and who fixes a defect at the seam.
  5. Reconcile the factory schedule with the lender's Set the manufacturer's deposit and milestone schedule against the lender's inspection-gated draw schedule, and ask the lender in writing how it treats payments for goods not yet on site. Ask counsel and the lender together how the 10% Builders' Lien Act holdback applies to off-site fabrication.
  6. Take the schedule from both ends Get a dated production slot with the conditions that hold and release it, and set it against the entitlement and permit path: as of right, variance, or development agreement. Use observed HRM durations rather than an assumed timeline, and treat the crane day as the fixed point both ends must hit.
  7. Settle warranty and handover in writing Obtain the manufacturer's warranty and the site contractor's warranty, define the seam between them and the process for a defect neither accepts. Confirm the inspection sequence, the final inspection, the lot-grading certificate and the occupancy permit requirements with the municipality before the modules ship.
Where the numbers come from

Every figure here carries its date and its source. Code adoption and tier dates are provincial (N.S. Reg. 198/2024, in force 1 April 2025); HRM's permit and demolition fee bases are the municipal schedule effective 1 April 2024; CMHC cost figures are the Housing Design Catalogue's Q1 2025 Halifax basis and CMHC loan terms are as at 6 November 2024. The permit and approval durations are medians Helio measured over HRM's own open building-permit and planning-application records to June 2026 through the Halifax Developments Map, whose methodology page (last updated 18 May 2026) dates and grades every fact; they are observed durations rather than commitments, and the recent cohort is right-censored, so the slowest waits are understated. Where a rule bears on a decision, read it at the source rather than from this page.

Common questions
Does a prefab factory quote include the foundation?

Ordinarily not. A quote prices the manufactured building delivered to a stated point. Foundations, site investigation, servicing, transport, the crane day, assembly, stitching, and the mechanical and electrical connections are bought separately. There is no standard division of factory and site work, so ask for a written scope schedule setting out what is in the module and what the manufacturer expects to find waiting on site.

Is a modular building Part 9 or Part 3 in Nova Scotia?

That depends on size and occupancy, not on how it is built. Under the National Building Code as adopted in Nova Scotia, Part 9 applies only to buildings of three storeys or fewer with a building area of not more than 600 m2 that are not an excluded major occupancy. Cross either threshold and the building follows Part 3, with a different engineering and review path.

Do I still need municipal inspections if the modules are certified in a factory?

The municipal file remains. In Halifax an occupancy permit is required before occupation, other than for single dwellings, sheds and pools, and it needs a valid building permit and a passed final inspection, and will not issue while a final lot-grading certificate is outstanding. What HRM inspects specifically on a factory-built building is not documented in the sources here, so ask for the inspection sequence in writing.

How does paying a factory affect a construction loan?

A manufacturer's deposits and fabrication milestones move money out before anything exists on site, while a construction lender advances in draws gated by inspection of completed on-site stages. Reconcile the two schedules before signing either, ask the lender how it treats payments for goods not yet on site, and ask counsel how the Builders' Lien Act 10% holdback applies to off-site fabrication.

Is there a mandatory new-home warranty in Nova Scotia?

No. Neither legislation nor regulation requires a developer of new condominiums to provide a new-home warranty, per CMHC's Nova Scotia fact sheet, so coverage is discretionary. On a prefab project there are two warranties to obtain, one from the manufacturer on the module and one from the site contractor on foundations, servicing, assembly and stitching, and the seam between them should be defined in the contract.
