An owner builder in BC is an individual that BC Housing authorizes to build one new home for their own use without a builder's licence or third-party home warranty. You must pass an exam, pay a fee, live in the home for at least a year and carry personal liability for defects for 10 years. And the authorization does not cover new duplexes or multiplexes: those need a Licensed Residential Builder. Here is how the two paths compare and which projects each one fits.
What is owner builder authorization in BC?
Under the Homeowner Protection Act, anyone building a new home must either be a Licensed Residential Builder or hold an Owner Builder Authorization from BC Housing before construction starts. The authorization is for an individual building "a new home for personal use". A licensed builder must register the home and enrol it in warranty before the building permit is issued; the New Home Registration Form is the proof the municipality sees.
To qualify, BC Housing's owner builder bulletin says you must:
- Be an individual, not a company (a family farm corporation director is the exception).
- Hold a registered interest in the land: fee simple, a life interest or a lease of at least 15 years, registered in your name.
- Build a single dwelling unit that is a detached home, attached to a pre-existing building older than 10 years, or attached to a new non-residential building.
- Not have received another authorization recently (see waiting periods below).
- Pass the Owner Builder Authorization Exam.
Owner builder vs licensed builder: side by side
| Owner builder | Licensed Residential Builder | |
|---|---|---|
| Who | An individual building one home for personal use | A person or company that manages all or substantially all construction of new homes |
| Qualification | Pass a 100-question exam with 70% or more | 24 months managing or supervising residential construction in the past 5 years, plus 7 competency areas |
| Fees | $425 authorization fee, $50 of it non-refundable | $600 application, $500 annual renewal, $40 per new home; $750 per unit reconstruction fee for multi-unit buildings in the coastal climate zone |
| Home warranty | Usually none | Required on every new home: 2 years materials and labour, 5 years building envelope, 10 years structure |
| Defect liability | You, personally, for 10 years to later buyers | Covered by the warranty provider, up to the policy limits |
| Selling or renting | Not during construction or for 1 year after the occupancy permit; disclosure notice to buyers for 10 years | No occupancy restriction |
| New duplex or multiplex | Not permitted | Permitted |
| Managing the build | You must build or directly manage it yourself | The builder manages it |
The licensing figures come from BC Housing's licensing pages (content current as of September 22, 2026). The owner builder fee comes from BC Housing's bulletin, last revised in 2018; BC Housing's current exam page still describes a $375 refund on a denied application, which matches a $425 fee less the $50 non-refundable portion. Confirm the fee with BC Housing when you apply.
Can an owner builder build a duplex, fourplex or garden suite?
Not a new multi-unit building. BC Housing states: "We don't issue Owner Builder Authorizations for single dwelling units that are in or attached to new, multi-unit residential buildings." So a new duplex, triplex, fourplex or townhouse under the new SSMUH zoning needs a Licensed Residential Builder and warranty on each unit.
The exception is adding one unit to a building more than 10 years old. BC Housing's FAQ lists "the addition of a unit to convert a detached home to a duplex, or conversion of a duplex to triplex" in a pre-existing building older than 10 years as eligible. If you are planning a multiplex, start with our guide to how many units your Greater Victoria lot allows, then the rules for Langford or Saanich.
How does the owner builder exam work?
Per BC Housing's exam page, after your application is approved you receive an eligibility letter to book the exam, online with a remote proctor or in person. It has 100 multiple-choice questions, a 100-minute time limit and a 70% pass mark, and you get one attempt per application. It covers construction basics and your legal obligations under the Homeowner Protection Act.
What are the owner builder rules after the home is built?
- Live in it. You must use the home yourself for at least one year after first occupancy.
- Do not sell or rent it for a year. Per BC Housing's selling page, you "cannot offer to sell, sell, or rent the new home" during the year after the occupancy permit. An early-sale request for undue hardship carries a $100 processing fee.
- Disclose when selling. If the home is sold within 10 years, the seller must give buyers an Owner Builder Disclosure Notice before a purchase agreement.
- Carry the liability. You are personally liable to later buyers for defects for 10 years: 2 years materials and workmanship, 5 years envelope, 10 years structure.
- Wait before the next one. The bulletin sets a waiting period of 18 months after first occupancy of your first owner-built home, 3 years after the second and 5 years for each one after that.
Can an owner builder hire a contractor?
You can hire individual trades, such as an electrician, plumber or framer. You cannot hire someone to manage the build for you. BC Housing's bulletin says that if an owner builder engages a builder, construction manager or project manager to perform those functions, both parties commit an offence under the Act and could face penalties of up to $25,000. If you want a general contractor to run the job, that contractor must be a Licensed Residential Builder and the home must be enrolled in warranty.
Which path is right for you?
Owner building can make sense for a single detached home you plan to live in, if you have the time to manage trades, inspections and the schedule, and you accept 10 years of personal liability. It does not fit an investment property you want to rent right away, a home you might sell soon, or any new multi-unit build.
A licensed builder costs more up front but brings third-party warranty that protects you and later buyers, and handles municipal permits and inspections. Check any builder on BC Housing's Licensed Builder Registry and read our guides to the 2-5-10 home warranty in BC and choosing a custom home builder in Victoria. For budgeting either path, our Victoria build cost guide and the free build cost estimator show where the money goes, and DCCs are covered in our development cost charges guide.
