Deck & Patio in a Strata — Limited Common Property Creates a Split Responsibility

idea

Claim: In a BC strata, patios, balconies, and ground-floor outdoor areas are almost always Limited Common Property — the strata corporation owns them structurally, but the resident has exclusive use. This split produces a maintenance ambiguity that catches owners off-guard: the strata is typically responsible for the structure (membrane, railings-as-structure, drainage), while the owner is responsible for surface upkeep — unless your registered bylaws say otherwise.

Mechanism

How LCP is created: The strata plan drawing designates each area as strata lot, common property, or limited common property. LCP is common property that has been assigned for the exclusive use of one strata lot. A balcony or patio shown outside your strata lot boundary on the strata plan is almost certainly LCP.

Default maintenance split under Standard Bylaw #8:

  • Strata corporation: responsible for all LCP repair and maintenance that occurs less often than once per year — this includes structural repairs, membrane replacement, major drainage work, and railing replacement as a structural element.
  • Owner: responsible for maintenance that occurs more than once per year — surface cleaning, keeping drains clear, sweeping, moving furniture.

How bylaws shift this: SPA s. 72(2) allows the strata to pass bylaws that transfer LCP maintenance obligations to the owner. Some stratas make owners responsible for the entire patio surface including the waterproof membrane; others maintain the same default split. You must read your registered bylaws — the strata plan tells you it’s LCP; the bylaws tell you who fixes what.

Alterations require strata council approval: Under SPA s. 68 and Standard Bylaw 8, any structural alteration to LCP — adding a pergola, replacing decking material, changing the membrane, adding built-in planters — requires strata council approval before you proceed. Municipal permit approval is separate and does not substitute for strata approval.

If water from the deck damages the unit below: The strata claims on its insurance; its deductible may be charged back to the owner whose deck was the source, under the same SPA s. 158 mechanism that applies to hot water tank leaks. Whether the strata or the owner above is responsible depends on where the membrane sits in the strata plan and the bylaws — not assumption. → The Strata Insurance Circularity Problem

Scope

This idea covers strata (condominium / townhouse / apartment) settings in BC where patios and balconies are LCP. It does not apply to:

  • Detached homes with a deck (owner responsibility, no LCP split)
  • Common property outdoor areas (rooftop terraces, shared courtyard) — those are the strata’s domain entirely with no owner-use assignment
  • Commercial strata

Idea Compass

North: Where this comes from

  • deck-patio (Home Systems) — the parent component; strata reality section
  • Strata Property Act ss. 68, 72 — the governing statute
  • Province of BC — Division of Repair Duties in a Strata1

East: Tensions / failure

  • The “strata owns the structure” default can be overridden by bylaws, creating situations where an owner is surprised to discover they’re responsible for the membrane after a breach
  • Municipal permit approval and strata council approval are independent requirements — you need both for any alteration
  • → The Strata Insurance Circularity Problem — the liability chain when a deck leak travels to a unit below
