A half duplex is one of two dwelling units sharing a common wall or forming part of the same building, with each side capable of being owned separately. Under the Strata Property Act, SBC 1998, c. 43, a stratified half duplex is a strata lot subject to a strata corporation, bylaws, and ongoing strata fees. A non-strata half duplex is held as freehold title inclusive of the underlying land, with no strata corporation or strata fees. Whether a half duplex is strata or non-strata is determinable from the registered title and, where applicable, a filed Strata Plan under the Land Title Act, RSBC 1996, c. 250. Financing conditions and lender requirements may differ between the two ownership structures; verify current lending criteria with a licensed mortgage professional. For advice on ownership structure, title review, or tax implications, verify current details with a BC lawyer, notary, or licensed tax professional.

Frequently Asked Questions

What is the legal difference between a strata half duplex and a non-strata half duplex in British Columbia?

A strata half duplex is a strata lot created under the Strata Property Act, SBC 1998, c. 43, governed by a strata corporation with shared ownership of common property and common expenses (strata fees). A non-strata half duplex is owned in fee simple under the Land Title Act, RSBC 1996, c. 250, meaning the owner holds title to both the structure and the underlying land without any strata corporation or strata fees. The distinction is visible on the registered Strata Plan (if stratified) and on the title documents at the BC Land Title Office. Verify the registered title and zoning for your specific property with a BC lawyer or notary before purchasing.

Are strata fees mandatory for a strata half duplex, and what do they typically cover?

Yes. Under the Strata Property Act, SBC 1998, c. 43, all strata lot owners must pay strata fees (contributions to common expenses) as determined by the strata corporation to fund insurance, maintenance of common property, contingency reserve fund contributions, and other shared costs. Non-strata half duplexes have no strata corporation and therefore no strata fees; the owner is solely responsible for all maintenance, insurance, and property costs. The amount and allocation of strata fees are governed by the strata corporation's budget and bylaws — verify current strata documents with the strata corporation or your BC lawyer or notary before purchase.

Does the Property Transfer Tax differ between strata and non-strata half duplexes in BC?

No. Property Transfer Tax (PTT) under the Property Transfer Tax Act, RSBC 1996, c. 378, is calculated on the fair market value of the property regardless of whether it is strata or non-strata. The general rates are 1% on the first $200,000 (as of 2026-07-27 — verify current), 2% on the portion between $200,000 and $2,000,000 (as of 2026-07-27 — verify current), 3% on the portion between $2,000,000 and $3,000,000 (as of 2026-07-27 — verify current), and 5% on amounts above $3,000,000 (as of 2026-07-27 — verify current), plus any applicable Additional PTT. First-Time Home Buyer and Newly Built Home exemptions may apply if eligibility requirements are met — verify current thresholds and your eligibility with a BC lawyer, notary, or the BC Ministry of Finance before closing.

Can I get mortgage insurance (CMHC, Sagen, or Canada Guaranty) on both strata and non-strata half duplexes?

Generally, yes, but lender and insurer eligibility criteria may differ. Canada Mortgage and Housing Corporation (CMHC) and private mortgage insurers typically insure both, but non-strata half duplexes are often preferred by lenders because ownership is simpler and there are no strata corporation risks (such as underfunded reserves or special levies). Some lenders may impose stricter loan-to-value ratios or require higher down payments for strata properties. Verify current underwriting requirements and mortgage insurance eligibility for your specific property with your mortgage broker or lender and consult a BC mortgage professional before making an offer.

Who is responsible for exterior maintenance and roof repairs on a strata half duplex versus a non-strata half duplex?

For a strata half duplex, the Strata Property Act, SBC 1998, c. 43, and the strata corporation's bylaws typically assign responsibility for common property (including roof, exterior walls, and shared structure) to the strata corporation, funded through strata fees. For a non-strata half duplex owned in fee simple, the individual owner is solely responsible for all exterior maintenance and roof repairs, unless a separate co-ownership or cost-sharing agreement exists between the two half-duplex owners (rare and must be registered on title). Always review the strata's Form B Information Certificate, bylaws, depreciation report, and engineering reports (if strata) or have a BC lawyer or notary review title and any registered easements or covenants (if non-strata) before purchase.

Is a bare land strata half duplex the same as a non-strata half duplex?

No. A bare land strata half duplex is still a strata lot created under the Strata Property Act, SBC 1998, c. 43, but with minimal or no common property (the strata lot itself includes the land and the dwelling). There is still a strata corporation, strata fees (though often lower), and governance under the Strata Property Act. A non-strata half duplex is not stratified at all and is owned entirely in fee simple under the Land Title Act, RSBC 1996, c. 250, with no strata corporation. Verify the registered Strata Plan and title at the BC Land Title Office with a BC lawyer or notary to determine the exact ownership structure.

Can I subdivide a non-strata half duplex in Metro Vancouver or Langley to create two separate fee-simple lots?

Possibly, but it depends on municipal zoning bylaws under the Local Government Act, RSBC 2015, c. 1, and compliance with the Small-Scale Multi-Unit Housing (SSMUH) provincial legislation (Housing Statutes (Residential Development) Amendment Act, 2023, effective July 1, 2024 for most municipalities — as of 2026-07-27 — verify current). Many Metro Vancouver and Langley municipalities now permit subdivision of duplexes into two fee-simple lots, subject to minimum lot size, frontage, servicing, and other requirements. Verify current zoning, subdivision approval requirements, and servicing with the local municipal planning department and consult a BC lawyer, land surveyor, or land use planner before attempting subdivision.

Does the BC Speculation and Vacancy Tax apply differently to strata versus non-strata half duplexes?

No. The Speculation and Vacancy Tax Act, SBC 2018, c. 46, applies to residential property in designated taxable regions (including Metro Vancouver and certain other areas — as of 2026-07-27 — verify current) based on use and ownership, not on whether the property is strata or non-strata. Owners who are not exempt must declare annually; the tax applies if the property is not the owner's principal residence or qualifying long-term rental. Verify your declaration and exemption status annually with the BC Ministry of Finance and consult a BC tax professional if you are uncertain about your obligations.

Can the owner of one side of a non-strata half duplex deny the other side owner access to shared infrastructure (e.g., driveway, utilities)?

Generally, no, if there are registered easements, statutory rights of way, or covenants on title under the Land Title Act, RSBC 1996, c. 250. Non-strata half duplexes often have registered easements for shared driveways, sewer laterals, water lines, or party wall maintenance. If no easement is registered, disputes may require negotiation or court resolution. Always have a BC lawyer or notary review title for all registered encumbrances, easements, covenants, and party wall agreements before purchase, and obtain title insurance to protect against unregistered or defective easements.

If I buy a strata half duplex, do I get voting rights in the strata corporation?

Yes. Under the Strata Property Act, SBC 1998, c. 43, each strata lot owner is entitled to vote at general meetings of the strata corporation, with voting allocation determined by unit entitlement (unless the strata plan or bylaws specify otherwise). For a two-lot strata (common in half duplexes), each owner typically holds 50% (as of 2026-07-27 — verify current) of the vote, meaning both owners must agree on major decisions requiring a ¾ or unanimous vote. Review the registered Strata Plan, bylaws, and meeting minutes, and consult a BC lawyer or notary familiar with the Strata Property Act before purchasing to understand your governance rights and obligations.
