The 2-5-10 Home Warranty, for a Multiplex

BC requires new home warranty insurance on every home a licensed builder sells. A multiplex has a wrinkle a single-family house does not: each unit is its own home for warranty purposes, and the shared building envelope sits underneath all of them at once.

Key Takeaways

✓ The 2-5-10 warranty is mandatory, not optional, under BC's Homeowner Protection Act for any home sold by a licensed builder.
✓ Coverage is 2 years labour and materials, 5 years building envelope, 10 years structure, each up to $200,000 per home.
✓ In a multiplex, each unit needs its own policy — a fourplex represents up to four separate $200,000 coverage envelopes, not one shared pool.
✓ BC Housing and the BC Financial Services Authority (BCFSA) jointly administer the program; disputes go through BC Housing's Homeowner Protection Office.

What Each Coverage Period Protects

The 2-5-10 warranty is third-party insurance required under BC's Homeowner Protection Act. It is named for its three coverage windows, which run from the date the home is occupied, not the date construction started.

BC's 2-5-10 New Home Warranty Coverage
Coverage Period	What It Covers	Combined Limit
2 years	Labour and materials on the whole home	Up to $200,000 per home
5 years	The building envelope (the parts that keep water out: roof, cladding, windows)	Up to $200,000 per home
10 years	The structural frame (foundation, load-bearing walls, structural systems)	Up to $200,000 per home

The Multiplex Wrinkle: One Policy Per Unit

A single-family house has one warranty policy. A multiplex does not get one policy for the whole building — each dwelling unit is its own home under the Homeowner Protection Act and needs its own enrollment, purchased individually through the licensed builder.

That matters most for the 5-year building envelope tier. The roof, cladding, and windows of a fourplex are shared physical infrastructure sitting above and around four separately warranted homes. A leak that starts above one unit can show up as damage in another, and the owners of the affected units may need to coordinate their claims even though each is filing under a separate policy.

How the 2-5-10 warranty splits across a multiplex
Question	Answer for a multiplex
Does one warranty cover the whole building?	No. Each dwelling unit in a multiplex needs its own 2-5-10 policy, purchased individually through the licensed builder.
Who owns the claim if the roof leaks?	The building envelope (5-year coverage) is shared infrastructure, but each affected unit's owner files under their own policy. In a strata, the strata corporation and the owners often need to coordinate claims together.
What if the multiplex is later stratified?	The warranty follows the unit, not the original owner. A buyer of a resale unit inside the coverage window is still protected for whatever time remains on the 2, 5, or 10-year clock.

What Happens When the Building Is Stratified

A warranty policy is tied to the individual unit, not to the original owner. If a multiplex is stratified and units are resold, each unit's remaining coverage transfers to the new owner for whatever time is left on the 2, 5, or 10-year clock. A buyer purchasing a resale unit in year 6 still has 4 years of structural coverage remaining, even though they were not the original buyer.

Building envelope claims that touch shared elements (the roof, the exterior walls) after stratification typically run through the strata corporation, since the strata now owns and maintains the common property. Owners should keep their individual warranty documentation even after stratification, since it is what proves the coverage window for their specific unit.

The Owner-Builder Exemption

BC Housing's Licensing and Consumer Services branch runs an owner-builder exemption process for homes an owner intends to live in themselves rather than sell. If you are building a multiplex and plan to occupy one unit while renting out the others (not selling them), the units you keep may fall under this exemption. Any unit you intend to sell to a third party generally still needs coverage through a licensed builder and warranty provider.

The rules here turn on intent and on what you actually do with each unit, so confirm your project's exemption status directly with BC Housing before assuming any unit is exempt.

Frequently Asked Questions

What is the 2-5-10 home warranty in BC? +

It is third-party new home warranty insurance required under BC's Homeowner Protection Act for every home built by a licensed residential builder. It gets its name from three coverage periods: 2 years for labour and materials, 5 years for the building envelope, and 10 years for the structural frame, each up to a combined limit of $200,000 per home. There is no opting out — a licensed builder cannot legally sell a new home in BC without it.

Does a multiplex need one warranty or one per unit? +

One per unit. Each dwelling in a duplex, triplex, fourplex, or sixplex is its own home for warranty purposes and needs its own 2-5-10 policy, purchased individually through the builder at the time of sale or, for an owner-built rental multiplex, at completion.

What does the 2-year labour and materials period actually cover? +

Defects in materials, labour, and workmanship that fail within the first two years of occupancy, including things like faulty electrical work, plumbing leaks not tied to the building envelope, and defective finishes. This is the broadest but shortest window of the three.

What counts as the building envelope for the 5-year coverage? +

The parts of the building that keep water and air out: the roof, exterior cladding, windows, doors, and the waterproofing behind them. Water penetration is historically the most common and expensive claim category under BC's warranty system, which is why this tier gets its own 5-year window instead of falling under the shorter 2-year period.

What does the 10-year structural coverage protect? +

Major structural defects: foundation failure, structural framing failure, or anything that compromises the load-bearing system of the building. This is the longest window because structural problems are the slowest to surface and the most expensive to fix if missed.

Who regulates the 2-5-10 warranty in BC? +

BC Housing and the BC Financial Services Authority (BCFSA) jointly administer new home warranty insurance under the Homeowner Protection Act. Licensed builders must be registered with BC Housing's Homeowner Protection Office (HPO), and every home they build must be enrolled in a warranty program before it is occupied.

What happens if my warranty claim gets denied? +

You can dispute the denial through BC Housing's Homeowner Protection Office. The HPO does not act as an insurer itself, but it oversees the licensed warranty providers and can intervene if a builder or provider is not meeting its obligations under the Act.

Does the $200,000 cap apply per unit or per building in a multiplex? +

Per unit. Each home carries its own combined limit of up to $200,000 across all three coverage tiers, because each unit has its own separate policy. A fourplex therefore represents up to $800,000 in total combined warranty coverage across its four units, not a single shared $200,000 pool.

Does an owner-builder building a multiplex on their own lot need warranty coverage? +

It depends on whether the owner-builder is selling the units or living in them. BC's Homeowner Protection Act has an owner-builder exemption process for homes the owner intends to occupy, but any unit that will be sold to someone else generally requires enrollment through a licensed residential builder and warranty provider. Confirm your specific project's status with BC Housing's Licensing and Consumer Services branch before assuming an exemption applies.
