The walkthrough and the warranty on a new multiplex home

Shortly before you complete, you walk through the finished home with someone from the seller's team and write down everything that is wrong with it. That list decides what gets fixed without an argument. After you move in, a separate protection takes over: every new home built by a Licensed Residential Builder in British Columbia carries mandatory warranty insurance, described by BC Housing as 2 years on materials and labour, 5 years on the building envelope, and 10 years on the structure.

The two things are related but they are not the same. The walkthrough is about finish. The warranty is about defects. Knowing which is which saves a lot of frustration in the first year.

The short version

  • The walkthrough list is the record of what the seller agreed was wrong on the day. Write everything down.
  • BC's mandatory warranty covers 2 years materials and labour, 5 years building envelope including unintended water penetration, and 10 years structural defects.
  • The 2 year period has shorter sub-limits: 12 months on your own unit's non-common property, 15 months on common property in a strata building, and 24 months on major systems, exterior cladding, windows and doors.
  • Warranty insurance covers how the home was built. It does not cover cosmetic preferences or promises that were never in the contract.
  • Coverage is insurance, so it survives the company that built the home going out of business.

How to do a walkthrough properly

Give it real time. An hour is not enough for a home you are about to spend a large part of your life in, and the person walking with you will move at whatever pace you set.

Work systematically, room by room, and write down everything even when it feels petty. A scratch on a worktop is easy to have fixed before you move in and nearly impossible to argue about afterwards. Open every window and door, run every tap, switch on every light, open every cupboard, and check that the floor is level where two surfaces meet.

Bring someone whose eyes are fresh. You will be excited, which is exactly the state in which people miss things. A friend who has no emotional investment in the home will notice the door that catches.

  • Photograph everything you record, with something in shot for scale.
  • Get the list signed or acknowledged in writing before you leave.
  • Ask when each item will be fixed and who to contact about it.
  • Check that what was promised in the contract is actually there, including appliances and finishes.
  • Test the heating and cooling, even if it is the wrong season for it.
  • Look at the shared areas as well as your own unit, because those are yours too.

What the warranty covers, period by period

British Columbia requires third party warranty insurance on new homes built by Licensed Residential Builders. BC Housing sets out the minimum coverage in three layers, and it is worth understanding what each one is actually for.

The 2 year layer covers defects in materials and labour, with shorter limits on some categories. BC Housing states 12 months for detached homes and for the non-common property in strata units, 15 months for common property in multi-unit strata buildings, and 24 months for major systems including electrical, plumbing, heating, ventilation and air conditioning, as well as exterior cladding, windows, doors, and defects that make the home unfit to live in. Building Code violations are also covered where they create a health or safety risk or are likely to cause material damage.

The 5 year layer covers the building envelope, including unintended water penetration that could cause damage. The 10 year layer covers defects in load bearing parts or the overall structure, including defects that make the home unfit to live in.

What the warranty does not cover

This is where most disappointment comes from. Warranty insurance covers how the home was built. BC Housing is explicit that it does not cover cosmetic issues, personal preferences, or contractual expectations.

So a hairline crack in a wall that appears as a new home settles is usually not a claim. A cupboard door in a finish you did not expect is a contract question rather than a warranty question. Normal wear from living in the home is yours. Damage you cause is yours.

The other thing worth knowing is that a warranty claim has time limits attached to each layer, and those limits run from when coverage started rather than from when you noticed the problem. If something looks wrong, report it in writing when you see it rather than waiting to see whether it gets worse.

Making a claim without making it harder than it needs to be

Report in writing, describe what you observe rather than what you think caused it, include photographs and dates, and keep a copy of everything you send.

In a strata building, work out first whether the problem is in your own unit or in the shared parts of the building, because that decides whether you or the strata corporation is the one who reports it. Getting this wrong wastes weeks.

If a claim is refused and you disagree, the refusal will refer to a specific term in the policy. Ask for that term in writing and take it to somebody who reads insurance policies for a living. In our experience the arguments that succeed are the ones anchored to the wording, not to how unfair the situation feels.

The first year, month by month

A new home behaves differently in its first year than it will afterwards, and knowing what is normal saves you worrying about the wrong things.

In the first few months you will notice small movement as the home settles. Hairline cracks where two surfaces meet, doors that need adjusting, a floor that creaks in one spot. Most of this is ordinary and much of it is not a warranty matter, though it is worth reporting anything you are unsure about in writing so the date is recorded.

Somewhere in the first year the shorter warranty sub-limits start expiring. BC Housing sets 12 months for non-common property in a strata unit and 15 months for common property in a multi-unit strata building, so the window on the smallest items closes first. Put both dates in your calendar on the day you move in, and walk the home properly a few weeks before each one.

The other first year job is learning how the building is run. In a small multiplex the owners are the strata council, which means the people who decide what gets repaired are you and your neighbours. Read the bylaws, find out who holds the documents, and go to the first annual general meeting. It is a couple of hours that makes the next ten years easier.

Get to know your neighbours in that first year as well, because in a four home building they are the whole strata. The practical business of running the place, agreeing what to repair and what to leave, is much easier between people who have met.

Keep a simple log through that year: what you noticed, the date, what you reported and to whom, and what happened. It sounds fussy and it takes a minute at a time. When a small problem turns out to be a symptom of a larger one three years later, that log is the difference between a claim supported by dates and photographs and a claim supported by your memory.

  • Move-in day: diarise the 12 month and 15 month warranty dates
  • First 3 months: report anything you are unsure about in writing, with photographs
  • Around 10 months: walk your own home carefully before the 12 month limit
  • Around 13 months: raise common property items with the strata before the 15 month limit
  • Year one: read the bylaws and attend the first annual general meeting

Questions buyers ask

The 2-5-10 warranty is the mandatory home warranty insurance carried by new homes built by a Licensed Residential Builder in British Columbia. BC Housing describes the minimum coverage as 2 years on defects in materials and labour, 5 years on the building envelope including unintended water penetration, and 10 years on structural defects in the load bearing parts of the home.
No, and this is the part buyers most often get wrong. BC Housing sets shorter limits inside the 2 year materials and labour period: 12 months for detached homes and non-common property in strata units, 15 months for common property in multi-unit strata buildings, and 24 months for major systems, exterior cladding, windows, doors and defects that make the home unfit to live in.
No. BC Housing states that all new homes built by a Licensed Residential Builder must have home warranty insurance. Because it is insurance rather than a promise from the company that built the home, the coverage remains in place even if that company ceases to exist, which is a meaningful difference for a buyer looking at a long coverage period.
Home warranty insurance covers problems with how the home was built. BC Housing is explicit that it does not cover cosmetic issues, personal preferences, or contractual expectations. Normal wear from living in the home and damage you cause yourself are also outside it. A finish that is not what you expected is a contract question for the seller rather than a warranty claim.
Take longer than the appointment suggests. There is no fixed length, and the person walking with you will generally move at your pace, so allow a couple of hours for a family sized home and work room by room. The list you produce that day is the record of what the seller acknowledged was wrong, and it is far harder to add to afterwards.
Bring a camera, something to write with, a copy of the contract listing the finishes and appliances you were promised, and a second person whose judgement you trust. Photograph every item you record, note the date, and ask for the finished list to be acknowledged in writing before you leave the home.
Items recorded at the walkthrough are for the seller to put right, and the timing should be agreed at the same time as the list. Ask for a named contact and a date rather than a general assurance. If an item is still outstanding after you move in, having the acknowledged list makes the conversation short.
Report it in writing as soon as you notice it, describing what you can see rather than what you think caused it, with photographs and dates. Warranty periods run from when coverage started rather than from when you spotted the problem, so a delay in reporting can move a repairable item outside the window that would have covered it.
In a strata building, defects in common property are normally reported by the strata corporation rather than by an individual owner, while problems inside your own unit are yours to report. Work out which side of that line your problem sits on before you file anything, because sending a claim through the wrong route costs weeks.
Home warranty insurance in British Columbia attaches to the home rather than to the first buyer, so the remaining coverage continues for a later owner within the original periods. The clock does not restart on sale. If you are buying a home that is a few years old, ask which parts of the 2-5-10 coverage are still running.
Bringing your own inspector to a new home walkthrough is allowed by many sellers and is worth asking about early, because it usually needs to be arranged rather than sprung on the day. An inspector will check things a buyer cannot easily assess, and the cost is small next to the price of the home.
Check that what you were promised is actually there: the appliances, the finishes, the storage, the parking space and the outdoor space named in your contract. Missing or substituted items are contract matters rather than warranty matters, so they are easiest to resolve before completion while the seller still needs something from you.
