Write down what you saw. Match it to a document that proves it. Send whatever is still open to the person qualified to answer it, before the subject deadline.

Buying a detached house in Coquitlam or Port Coquitlam means taking on the land, the building, and every right and duty attached to them. Much of it cannot be seen at a showing. It sits in a registry, a city file, a buried pipe, or the soil. This guide sets out the checks a buyer can make before committing, in the order a purchase needs them, with the person who performs each one.

Every chapter uses the same three columns. What you can observe yourself. What a document proves. What needs a qualified professional. Keeping those apart stops an observation from turning into a conclusion, and stops a document from being read for more than it says. The checks tell you what is known, what is still open, and who can answer the rest. The decision to buy stays with you.

This guide assumes you already have a house in mind. For the search itself, from setting a brief to viewing homes, use the home buying guide. For the costs and taxes that come with a purchase, see the costs and taxes guide. If you are on the other side of a sale, the selling a home guide covers the seller's duties.

The chapters

Before the offer: checks that need no one's permission

Some checks need only an address or a parcel identifier. Do these first, because they tell you which questions the offer must leave room for.

Get a copy of the title. LTSA's page on finding information on a title says a title lists the owners, the legal description, the parcel identifier, and the charges and legal notations registered against it. You need the parcel identifier to search, because LTSA says a civic address cannot be used.

For a house built in recent years, search BC Housing's New Homes Registry. BC Housing says it shows whether a new home has a warranty policy, whether a licensed builder built it, or whether it was built under an owner builder authorization.

Look at the free maps: the city's flood and watercourse layers, the provincial floodplain maps, the wildfire threat maps, and the contaminated site layer in iMapBC. Then ask the seller, through your real estate professional, for the documents only the seller has: the disclosure statement, any tenancy agreement, past inspection or drain reports, oil tank removal records, radon results, and warranty papers.

The offer and the three day rescission period

For most resale purchases, the property checks happen inside subject clauses in the contract of purchase and sale. BCFSA's consumer guide to property inspections says a seller does not have to accept an offer with an inspection subject. If the seller removes it, BCFSA advises speaking with your real estate professional about the risks. The journal article on subject-free offers looks at that choice in more detail.

Separate from subjects, British Columbia has a Home Buyer Rescission Period. BCFSA says it applies to a detached house, among other property types, and lets a buyer rescind within three business days after the offer is accepted, excluding weekends and holidays. The buyer must give written notice before the period ends and pay a rescission fee of 0.25 percent of the offer price. The right cannot be waived. On an explicitly hypothetical $1,500,000 offer, that fee would be $3,750. Whether it applies to your contract, and how to use it, is a question for your real estate professional and lawyer.

During the subject period: checks with a deadline

Once the offer is accepted, the subject deadline sets the pace. Several checks need either access to the house or the purchase agreement itself. Coquitlam's building permits FAQ, for example, says realtors and prospective buyers must show a valid purchase agreement to obtain plans or a form survey. Book these on the day the offer is accepted.

The checks that fit inside the subject period are the home inspection, the city permit file, a survey, an oil tank search, a sewer and drain camera inspection, the suite's permit status, the lender's decision and the insurer's answer. Each one needs a date for the result that falls before the subject deadline, with time to act on what it finds. If a provider cannot deliver before the deadline, tell your real estate professional at once. The choices then include asking the seller for a longer subject period, agreed in writing, or narrowing the question to one that can be answered in time.

After subjects are removed

Some steps can only start once the sale is firm. The clearest is a notice to a tenant for the buyer's own use. Section 49 (5) of the Residential Tenancy Act allows it only after all the conditions on which the sale depends have been satisfied and the purchaser has asked the seller in writing. The notice period, the form and the compensation are in the tenanted home chapter.

Before completion, your lawyer or notary does the legal work. BCFSA's guide to completing your purchase lists searching the title for other people's rights and for registered easements or restrictive covenants, making sure the seller's mortgage is discharged if required, and registering you as owner. It also notes that the completion date and the possession date are not necessarily the same.

Watch for late charges. Section 20 of the Builders Lien Act allows a claim of lien to be filed up to 45 days after work is completed or abandoned. If the seller renovated recently, ask your lawyer or notary how that window is handled.

After completion

A few checks run longer than any subject period. Health Canada says a radon test should run for at least 3 months, as its page on testing your home explains. If there is no past result, plan the test for your first fall or winter in the house. Keep every report from the purchase in one place. When you sell, the next buyer will ask many of the same questions, and your records will answer them.

Using this guide

Pick the chapters that match the house. An older house may raise asbestos, oil tank and drainage questions. A newer one raises warranty questions. A suite or a tenant raises permit and tenancy questions. A lot near a creek raises setback questions, which the land and zoning guide takes further. For each open question, write down who will answer it and by when, and make that date earlier than the subject deadline.

Keep one list for the whole purchase. Give each line the question, the source you used, the person responsible, the date you expect an answer, and the answer when it arrives. Mark a line closed only when a document or a qualified person has answered it. A line that stays open on the subject deadline is a decision you are making without that answer, so raise it with your real estate professional and your lawyer or notary before that day.

Questions and answers

Which property checks should I do before making an offer on a house?

Start with the checks that need no permission from the seller. Search the address in BC Housing's New Homes Registry, get a copy of the title by its parcel identifier, and look at the city's flood and service maps. Ask the seller for the disclosure statement, any tenancy agreement and past reports. These show which questions need a subject clause and which specialists to line up.

Which checks usually depend on a subject clause?

The checks that need access to the house or the purchase agreement. BCFSA's inspection guide discusses offers with a property inspection subject clause and says a seller does not have to accept one. Coquitlam's building permits FAQ says prospective buyers must show a valid purchase agreement to see plans or a form survey. Inspections, city file reviews, surveys, oil tank searches and sewer camera work all fit inside the subject period.

Is the three day rescission period a substitute for subjects?

No. BCFSA says the Home Buyer Rescission Period lets a buyer rescind an accepted offer on a detached house within three business days, with written notice and a fee of 0.25 percent of the offer price. It cannot be waived. It is a cancellation right with a cost, and three business days leaves little time for inspections or record requests. Discuss both with your real estate professional.

Who carries out each property check on a house purchase?

Different people. A licensed home inspector gives an opinion on condition. A lawyer or notary searches title and handles completion. A BC land surveyor certifies where buildings sit. City staff hold permit and service records. Environmental professionals search for tanks and test soil. Certified testers measure radon. Your lender and insurer answer their own questions. The table on this page lists each check and what it produces.

When can a tenant be given notice so I can move in?

Only after the sale is firm. Section 49 (5) of the Residential Tenancy Act lets the seller end a tenancy for a purchaser's use when the sale agreement was made in good faith, all conditions of the sale have been satisfied, and the purchaser asks in writing. The notice period and the tenant's rights then follow. The tenanted home chapter explains the timeline and the compensation.

Can a problem appear on title after I remove subjects?

It can. The Builders Lien Act allows a claim of lien to be filed up to 45 days after work is completed or abandoned, so recent renovations can lead to a claim after your first search. BCFSA's completion guide lists title searching among the lawyer's or notary's tasks. Ask them when they will search again and how the contract deals with a charge that appears late.

Which checks cannot be finished inside a subject period?

A radon test is the clearest example. Health Canada says a long term radon test should run for at least 3 months. Compare that with your subject deadline, then ask for past results or discuss a holdback with your lawyer. For surveys, searches and record requests, ask each provider for a completion date before you agree to the subject deadline.

What should I do if a check finds a problem before the subject deadline?

Write the finding down in plain words with its source, then send it to your real estate professional and your lawyer or notary the same day. The options depend on your contract and on what the seller agrees to. They can include more time, a price change, a repair before completion, a holdback, or not going ahead. Each option needs written terms.

Do I need all of these checks for every detached house?

Match the checks to the house. A house built before 1990 raises asbestos questions. One heated by oil in the past raises a tank question. A suite raises permit and tenancy questions. A house under ten years old raises warranty questions. A lot near a creek raises setback questions. Use your viewing notes and the seller's answers to decide which chapters apply, then confirm with your professionals.

Can a real estate professional tell me a house is sound?

A real estate professional can help you plan the checks, request records, and negotiate terms. Condition, legality and title are decided by other people: the inspector and specialists, the city, and your lawyer or notary. BCFSA's inspection guide advises speaking with your real estate professional about the risks of going without an inspection. The decision on what risk to accept is yours.
