Strata Unit Door Locks — What Is Owner Scope vs Strata Scope in BC

idea decision-rule

Claim: In BC strata, the unit entry door is legally contested territory — it may be common property (strata maintains, strata approves changes) or strata lot (owner maintains and can alter freely) depending on your strata plan and bylaws. Do not touch the lock until you have the answer in writing.

Mechanism

The Strata Property Act (SPA) assigns maintenance and repair duties based on where the component sits in the strata plan — strata lot vs common property vs limited common property (LCP). Exterior doors occupy a legally ambiguous position:

  • BC Government Guide 20 (the strata repair guide) states that the strata corporation maintains “doors, windows and skylights on the exterior of a building or that front on the common property.” This suggests the entry door itself is a strata obligation.
  • A 2024 BC Civil Resolution Tribunal decision (North Vancouver condo, reported CTV News November 2024) ruled that a condo entry door is common property — the strata corporation, not the owner, was responsible for replacing a vandalized lock.12
  • Standard Bylaw 2 requires owners to maintain their strata lot. But if the door is common property, Bylaw 2 does not apply to it — and Standard Bylaw 6 requires written strata approval before any owner alters common property.

What this means for lock changes:

  • If the door is common property → changing the lock (even just rekeying) is an alteration to common property → requires written strata approval under Standard Bylaw 6.
  • Some stratas also require the new cylinder to maintain compatibility with the building’s master-key system (so strata can access units under SPA emergency-access provisions).
  • If the door is classified as LCP assigned to your lot → you maintain it and may alter the lock, though exterior hardware appearance bylaws may still apply.
  • If the door is classified as part of your strata lot → you maintain and can rekey freely, subject to aesthetic bylaws.

The answer varies by strata and can only be found by reading your strata plan and registered bylaws. There is no universal BC rule. Many strata corporations have bylaws that modify the standard position.

The master-key question

Many BC strata buildings have a building master key that opens all unit cylinders, installed during original construction. These master keys:

  • Are often not disclosed to owners at purchase
  • Remain in circulation indefinitely unless the lock system is replaced
  • Are controlled by the strata, not the owner

Owners cannot be compelled to provide a personal key copy to the strata corporation. The SPA requires 48 hours written notice for routine strata access; emergency access has separate provisions. The strata cannot simply demand a key.3 But if a building master key exists and you rekey your lock to a non-master-compatible cylinder, the strata loses emergency access — this is why some stratas require master-key compatibility in any lock change.

Conditions (when the standard position is modified)

  • If your registered bylaws explicitly shift door responsibility to owners → owner scope; check for aesthetic restrictions anyway.
  • If your strata has adopted “Section” bylaws that further subdivide responsibilities.
  • If your building is a bare-land strata → door responsibility analysis differs; consult bylaws.

Scope (what this does not cover)

  • Building common-door entry systems (key fobs, key cards, intercom buzzers) — fully strata-controlled; owner has no alteration rights
  • Mailbox locks — Canada Post controlled
  • Garage parking gate codes — building operator or strata controlled
  • Detached home lock changes — no strata; owner has full freedom

The action sequence before touching any hardware

  1. Read your strata plan: is the entry door on your strata lot boundary, or is it common property?
  2. Read your registered bylaws: any clause about door locks, master keys, or exterior alterations?
  3. Email your strata manager: “Is our unit entry door strata lot or common property? Do I need written council approval to rekey or replace the deadbolt? Does the replacement need to be master-key compatible?”
  4. Get the answer in writing.
  5. If approval is needed, submit the written request to strata council (Standard Bylaw 6 process).
  6. Only then proceed with the locksmith.

Idea Compass

North: Where this comes from

  • locks-keys (Home Systems) — the parent note; this is the strata-specific complication to the move-in rekey action
  • SPA s. 72 — strata corporation’s duty to repair and maintain common property
  • Standard Bylaw 6 — owner must obtain written approval before altering common property

East: Tensions / failure

South: Where this leads

  • Strata MOC (your specific strata’s documents) — where the actual answer lives
  • vendor-roster (Home Systems) — the locksmith who understands strata restrictions and can work within them

West: What’s similar

  • water-heater (Home Systems) — same strata-ownership ambiguity: the water heater is usually owner-responsibility, but the strata plan and bylaws determine it; same “read the bylaws before acting” discipline
  • electrical-panel (Home Systems) — strata owners cannot pull homeowner electrical permits; same pattern of strata-imposed restrictions on in-unit alterations
