Custom Home Financing Options in BC: The Rules That Decide Your Route

Custom home financing options in BC come down to three things: whether you hold title to the lot, whether your project clears $1,500,000, and the order the province makes the paperwork happen in. A custom build is also not a simple purchase mortgage: on the day you sign there is no finished house to lend against.

Financing is the part of custom home construction that people research last and should research first, because in BC the order of the paperwork decides when the money arrives.

Custom Home Financing Options in BC Start With Who Owns the House

The product names are the easy part, and whether you can finance a custom build in Canada is answered at the national level. Three kinds of rule decide what happens here: law that binds a bank, conditions attached to mortgage insurance, and terms each lender sets for itself. Knowing which one you are reading keeps you off advice meant for someone else. Settle the financing before anything is built, because a lender brought in after the excavator has gone is asked to fund work it never approved.

Who Owns the House While It Is Being Built

When you buy a newly built home from a builder, the builder owns it while it goes up and your mortgage funds once at the end, against a finished house. On a lot you own, you hold title the whole way through, so the construction borrowing is yours to carry. That holds for every custom build, whoever lends and whether anything is insured. With no finished house to lend against, no whole house is funded in one advance; the money arrives in instalments as the building goes up.

How the Money Arrives, and What You Pay While the House Goes Up

How each advance is released is lender practice rather than published rule: it is checked against work that is actually finished, not work that is planned. Ask how many of those checks are included and what each extra one costs, because that changes the cost of your draw schedule.

Before each advance your lender works out what it would still take to finish the house and compares that with what is left in your facility. If finishing would cost more, the advance stops until you cover the difference. That is the clearest reason a fixed-price contract matters to a lender, and why a client portal with daily logs and progress photos earns its keep.

Lenders on a construction mortgage generally charge interest only on the money that has actually been advanced, not on the whole approved amount, so the payment starts small and grows with the house. What the construction loan does not cover is where you live in the meantime, so plan on carrying your rent or your current mortgage alongside it for the length of the build. Do those interest payments come out of your pocket each month, or are they added to the loan? Ask your own lender, because the two feel very different on a long build.

The 80% Rule, and Why $1.5 Million Changes Everything

One rule in federal banking law and one limit on mortgage insurance decide how much of your own money the project needs.

Why 20% Down Is the Floor on a Build at This Value

A bank cannot lend more than 80% of a residential property’s value unless the part above that line is insured. That is why banks keep coming back to 20% down: where insurance is not available, 80% is as far as a bank can lend. And mortgage loan insurance, which protects the lender rather than you, is not available once the home is worth $1,500,000 or more, so there is no low-down-payment route at that level.

A lot plus a custom build in Greater Vancouver commonly reaches that level, which puts most clients here outside mortgage insurance and means much of the advice they have read was written for insured buyers.

The Insured Tiers, for Builds Below the Ceiling

On an insured mortgage the minimum down payment is 5% on a home of $500,000 or less, and 5% on the first $500,000 plus 10% above it on a home between $500,000 and $1,499,999. Because the 30 year amortization for new builds is a mortgage insurance measure, it reaches a build financed below the $1,500,000 ceiling, which in practice means Abbotsford, parts of the Fraser Valley and some Kelowna parcels rather than a build at Greater Vancouver values.

The Qualifying Rate on an Uninsured Mortgage

The qualifying rate on an uninsured mortgage is the greater of the contract rate plus 2% or 5.25%, the 2% being a safety margin and the 5.25% a floor. Federally regulated lenders have to apply the minimum qualifying rate on an uninsured mortgage in full, and it is not a condition of mortgage insurance, so it does not go away when insurance does. That is most custom home clients here, who sit above the insurance ceiling.

The BC Gating Chain: Warranty Registration, Then Permit, Then the First Draw

Three things happen in a set order on a new home in BC, and the order decides when money can move:

  1. The home is registered for home warranty insurance.
  2. The municipality issues the building permit.
  3. The first advance is released against completed work.

Arranging your financing and applying for your permit run side by side rather than one after the other. Lenders want to see the plans, the costs and the permit before they commit.

Registration Comes Before the Permit

Registration for home warranty insurance has to happen before you can get a building permit, or before construction starts where no permit is required. It produces a new home registration form, which proves licensing and warranty coverage to the municipality when the permit application goes in. On a custom home your general contractor registers the home, not you, so it pays to check a builder’s licence and warranty coverage yourself.

The Building Permit a Municipality Cannot Issue Without Warranty Evidence

BC law does not let a municipality or regional district issue a building permit for a new home until the applicant shows evidence of warranty coverage or owner builder authorization, and that a licensed builder or owner builder will do the work. The permit is also a document a lender leans on when it values the finished house, so the first advance waits on the permit and the permit on the registration.

Development cost charges are payable before construction money starts flowing, and what the permits themselves cost in BC depends on your city. Your lender will also want insurance in place during construction, its own requirement rather than a published rule.

What the Coverage You Are Registering Actually Is

A home built by a licensed residential builder is an insured home, so insured coverage applies. BC’s statutory minimum is 2-5-10, and the two year materials and labour leg is tiered inside itself: 12 months on a detached home, 15 months on common property in a strata building, and 24 months on major systems such as electrical, plumbing, heating, ventilation and air conditioning, and certain exterior components. After that leg comes five years on the building envelope and ten years on structure. Those are the minimum coverage requirements for a new home in BC, and some policies provide more.

Versa Homes’ own Versa Shield coverage runs 3-6-11, which is longer than the statutory minimum on each of the three legs.

Minimum coverage on a detached home is capped at the lesser of the first owner’s purchase price and $200,000, and some policies provide more. A custom home built on land you already own does not have a purchase price in that sense, so ask your warranty provider in writing which figure they will apply to your home.

The Owner Builder Route, and What It Moves Onto You

An owner builder holds an authorization from the registrar, and that authorization satisfies the permit gate instead of warranty coverage. Owner builders are exempt from becoming licensed and from arranging third party warranty insurance. The exemption is from the insurance and the licence, not from the responsibility, and it leaves you personally liable for construction defects in the home for ten years. That ten years is your own liability rather than a policy someone else pays out on.

Where the Money Comes From, Route by Route

Your route is chosen for you by where your equity currently sits. How a land loan, a construction mortgage and a permanent mortgage fit together is settled ground; what changes is which rules reach each situation.

If You Already Own the Lot

Owning the lot outright is the cleanest position: the lot is the equity that makes a construction facility work. Where the financing is CMHC-insured, no advance is made against the bare lot and the equity in it has to go into the build rather than back to you. Above the insurance ceiling your lender sets its own terms, so ask what yours will do with the lot and get the answer in writing. Ask too whether the facility converts to a regular mortgage without a second application, because the alternative is re-qualifying mid-build.

If You Are Buying the Lot Now

Property transfer tax is payable when the lot is registered, at 1% on the first $200,000 of fair market value, 2% above $200,000 up to $2,000,000, and 3% above $2,000,000, with a further 2% on residential value above $3,000,000.

Lenders set their own terms on bare land, and they ask for more of your own money on a lot than on a finished house. Expect the lot to be the most cash-heavy part of the project, and ask your lender for the figure before you make an offer.

If Your Current Home Sells After You Move In

A home equity line of credit can reach 65% of the home’s value, and everything secured against that home, mortgage and line of credit together, is capped at 80%, so having equity and being able to reach equity are two different statements. That 80% is the same ceiling a bank works to on the new build, measured against a different property. A lender may ask only for interest on the regular payment, so the balance never comes down on its own.

If your current home sells after you move into the new one, you need short-term borrowing to cover the overlap. Those terms are set by the lender rather than by any rule, and lenders usually want a firm sale before they commit, so raise it early.

Taxes That Change Your Cash Flow Plan

The tax layer decides how much cash the project needs and when, and several of the rules that help are capped below what a custom home here is worth.

What the 5% GST on a New Home Actually Costs You

The tax on a new home in BC is the 5% federal GST, and nothing reduces it at this price point, so budget it as a cash line rather than expecting it back. Because the owner-built rebate stops at a fair market value of $450,000 at substantial completion, it does not reach a custom home in Greater Vancouver, and a claim under that threshold is filed with CRA within two years of the earliest of first occupancy, transfer of ownership or substantial completion. The rebates that exist are federal; there is no provincial new housing rebate in BC.

The First Time Buyer GST Rebate and Its $1.5 Million Ceiling

A first time buyer who builds, or hires someone to build, on land they own can recover up to $50,000 of the GST, with the rebate full on a home valued up to $1 million, phasing out between $1 million and $1.5 million, and nil at $1.5 million or more. Because the rebate only reaches builds that get under way in 2025 or later and start before 2031, and the home has to be finished and lived in before 2036, the start-date test is the one most people get wrong, so check your own construction start date against the CRA rules before you budget the rebate in.

Property Transfer Tax on the Lot, and the Refund You Apply For Later

A newly built home, for this purpose, includes a house built on a parcel of vacant land that has not been occupied since, so someone who bought a bare lot and built on it can apply for a refund of the tax paid on the land. It is a refund you claim after the house is finished, not an exemption you claim when you buy the lot.

Because the refund has to be applied for after the first anniversary of the registration date and within 18 months of it, the window is the part a homeowner can actually miss. Because the test adds the land’s fair market value to the cost of the newly built home and caps the total at $1,100,000, the refund reaches a modest build on a lower-cost parcel rather than a custom home at local values. You also have to move in and keep the home as your principal residence for the rest of that first year, with a partial refund by days of occupancy if you move out.

The window runs from the day the lot’s title is registered, not from the day you signed anything, so ask your BC lawyer or notary for the registration date in writing.

How to Stay Exempt From Speculation and Vacancy Tax While You Build

An exemption applies where there is not yet a residence on the property because of the stage of building activity, or where a residence cannot be occupied for 90 days in the calendar year because of construction. The exemption holds only so long as reasonable steps are being taken without undue delay to develop the property, so a lot sitting idle through a design pause is a different case from one moving through permitting. Applying for financing, applying for permits, entering into design or engineering contracts, clearing the site and building all count as building activity. Applying for your financing counts on its own.

Why the Lender’s Advance Is Not Your Builder’s Cash

On a custom build BC law requires you, as the owner, to hold back 10% of each payment on the construction contract rather than paying it all out. That 10% retention has no dollar threshold and does not start at $100,000: it is measured against the greater of the value of the work actually provided and the payment made on account. Separately, where the work and material under one contract total $100,000 or more, the money you hold back has to sit in a separate holdback account at a savings institution rather than in your builder’s hands. So the number your lender advances and the number your builder is owed are different, which is why your draw schedule and payment schedule are two separate documents.

Which Thresholds Reach a Custom Build in Greater Vancouver

Every rule that can rule you in or out has a number attached, and you can test each one against your own project before you talk to a lender.

Build the Financing Plan Into the Build Plan

The financing route and the build plan are one decision, because the documents a lender tests are documents your builder produces. Our fixed-price contracts give a lender a figure to measure against what it would take to finish the house, and our build schedule with pre-booked trades keeps a draw schedule on its dates. Carrying cost is what hurts when the dates slip, which is why Versa Homes stands behind a Move-In Date Commitment and pays $5,000 if we miss it. If you want a luxury custom home builder who can satisfy a lender as readily as a designer, book a consultation and we will work through your route.

Frequently Asked Questions

Who Registers a Custom Home for Warranty Insurance in BC?

On a custom home your general contractor registers the home for warranty insurance, and the registration has to be done before the building permit is issued. It produces a new home registration form, which is what proves licensing and coverage to the municipality when the permit application goes in, so it is worth asking your builder for a copy.

When Does Warranty Coverage on a Custom Home Start?

On a custom detached home, coverage starts at occupancy or the first occupancy permit, whichever comes first. That is different from a home built to sell, where it starts at first occupancy or transfer of title, whichever comes first.

Can I Take Cash Out of the Lot I Already Own to Fund the Build?

Where the financing is CMHC-insured, no advance is made against the bare lot and the equity in it has to go into the build rather than back to you. Above the insurance ceiling your lender sets its own terms, which are not published anywhere, so ask yours directly and get the answer in writing. Either way, owning the lot outright is a strong position for qualifying and a poor source of spending money, so plan the soft costs from cash or from equity in another property.

Can I Move My Mortgage to Another Lender at Renewal Without the Stress Test Again?

Often yes, once the house is finished and the mortgage is an ordinary one. Since November 2024 the qualifying rate no longer has to be applied when you move an existing uninsured mortgage from one federally regulated lender to another, as long as the loan amount and the remaining amortization do not go up, apart from a small allowance for transaction costs. Insured mortgage holders can also switch at renewal without a second stress test. None of that helps you qualify to build, which is a different application.

How Do I Check That a Mortgage Broker Is Registered in BC?

Mortgage brokers in BC are registered with the BC Financial Services Authority, which publishes a public search of registered professionals and organizations. Look up the person you are about to sign with, and check your builder’s licence while you are there.
