Strata Insurance Guide
Strata insurance in BC is two layers deep: the strata corporation carries a master policy on the building, and every owner needs their own unit policy on top. Since 2019, premiums have surged and deductibles have ballooned from $5,000 to $25,000-$50,000 — turning a burst pipe into a financial emergency. This is the complete guide to how strata insurance works for multiplex owners, what it costs, what it covers, and how to protect yourself.
Key Topics
Two Layers of Insurance
The strata corporation carries a master policy covering the building envelope, common areas, and third-party liability. Each unit owner carries a separate policy covering contents, improvements, personal liability, and — critically — the strata deductible. Neither layer is optional.
Master Policy Covers the Building
The master policy insures the building to full replacement value — the cost to rebuild from scratch, not market value. It covers the roof, exterior walls, foundation, common plumbing and electrical, shared areas, and the strata corporation's liability. The strata council arranges and pays for this through strata fees.
Your Unit Policy Fills the Gaps
Your individual policy covers personal contents, any improvements or betterments you have made (upgraded kitchen, hardwood floors), personal liability, additional living expenses if displaced, and loss assessment coverage for the strata deductible. Without it, a $25,000+ deductible comes out of your pocket.
Water Damage Is the #1 Risk
Water damage accounts for the majority of strata insurance claims in BC. Burst pipes, failed dishwasher connections, toilet supply line failures, and ice dams drive claims. Small stratas with 2-4 units are especially vulnerable because a single claim can consume the entire contingency reserve fund.
Deductibles Can Be Assigned to You
Under the BC Strata Property Act, the strata corporation can pass a bylaw assigning the deductible to the unit where the claim originated. Most stratas have this bylaw. If your dishwasher floods and damages two units below, you may owe the full $25,000-$50,000 deductible personally.
Disclosure Is Legally Required
The Insurance Council of BC requires strata corporations to disclose deductible amounts to all owners and prospective buyers. When buying, request the Form B Information Certificate ($35 fee) — it includes current insurance details, deductible amounts, and claims history. This is non-negotiable due diligence.
Master Policy vs Unit Owner Policy
Every strata-titled multiplex has two insurance layers. Understanding exactly what each covers — and the gaps between them — is essential before you buy.
| Coverage Area | Master Policy (Strata Corp) | Unit Owner Policy (You) |
|---|---|---|
| Building Envelope | Roof, exterior walls, foundation, windows | Not covered |
| Common Areas | Hallways, driveways, walkways, landscaping | Not covered |
| Shared Systems | Main plumbing, electrical, HVAC trunk lines | Not covered |
| Unit Interior (Original) | Developer-installed finishes (as built) | Not covered (already in master policy) |
| Improvements & Betterments | Not covered | Upgraded kitchens, flooring, bathrooms, built-ins |
| Personal Contents | Not covered | Furniture, electronics, clothing, valuables |
| Personal Liability | Not covered (only strata corp liability) | Injury to visitors in your unit, damage you cause |
| Loss Assessment / Deductible | Not covered (deductible is a cost, not a claim) | Pays the strata deductible if a claim originates in your unit |
| Additional Living Expenses | Not covered | Hotel, meals, temporary housing if unit is uninhabitable |
| Earthquake | Optional — many small stratas opt out due to cost | Optional rider available on unit policy |
| Overland Flood | May be excluded depending on location/insurer | May be excluded — check your policy |

BC Strata Deductible Trends
Water damage deductibles have been the single most disruptive change in BC strata insurance. Here is how they evolved — and where they stand today.

Water Damage: The #1 Risk for Multiplex Owners
Water damage drives the majority of all strata insurance claims in BC. In a small strata with 2-4 units, one burst pipe can trigger a chain reaction: the master policy covers the building repair, but the $25,000-$50,000 deductible may land entirely on the unit where the failure occurred.
Common Causes
- • Dishwasher supply line failure
- • Toilet supply valve rupture
- • Washing machine hose burst
- • Ice dam backup in winter
- • Failed caulking around tubs/showers
Prevention Measures
- • Install braided stainless steel supply lines
- • Replace washing machine hoses every 5 years
- • Install leak detection sensors under sinks
- • Know your unit shut-off valve location
- • Maintain caulking and grout in wet areas
What Your Unit Policy Should Cover
Use this checklist when shopping for your individual strata unit insurance policy. Every item below is either essential or strongly recommended for multiplex owners in BC.
Essential Coverage
- Loss Assessment / Deductible CoverageMinimum $50,000 — should match or exceed the highest deductible on the strata master policy
- Personal ContentsInventory your belongings and insure for replacement cost, not depreciated value
- Betterments & ImprovementsAny upgrades from original developer finishes: flooring, countertops, appliances, fixtures
- Personal LiabilityMinimum $1,000,000 — covers injury to visitors and damage you cause to other units
- Additional Living ExpensesCovers hotel, meals, temporary housing if your unit is uninhabitable during repairs
Strongly Recommended
- Sewer Backup CoverageCovers damage from sewer or drain backup into your unit — excluded on many base policies
- Identity Theft ProtectionIncreasingly bundled with home insurance — covers restoration costs and lost wages
- Earthquake Coverage RiderSeparate deductible (typically 5% of insured value). Expensive but consider Metro Vancouver seismic risk
- Overland Water / FloodCheck whether your base policy includes this — many exclude overland water by default
- Unit Improvement AppraisalDocument your improvements with photos and receipts so claims are not disputed
Insurance Costs: Small Strata vs Large Condo
Economies of scale work against small stratas. Here is how insurance costs compare between a typical 4-unit multiplex and a 150-unit condo tower in Metro Vancouver.
| Metric | 4-Unit Multiplex | 150-Unit Condo Tower |
|---|---|---|
| Annual Master Policy Premium | $8,000-$15,000 | $200,000-$400,000 |
| Per-Unit Annual Cost | $2,000-$3,750 | $1,333-$2,667 |
| Per-Unit Monthly Cost | $167-$312 | $111-$222 |
| Insurance as % of Strata Fees | 35-50% | 25-35% |
| Typical Water Damage Deductible | $25,000-$50,000 | $25,000-$100,000 |
| Deductible Impact per Owner (via levy) | $6,250-$12,500 | $167-$667 |
| Number of Insurers Willing to Quote | 2-4 | 6-10+ |
| Broker Willingness | Limited — small commission | High — large commission |
| Claims History Impact | One claim affects all 4 owners significantly | One claim diluted across 150 owners |
| CRF Deductible Buffer | Often insufficient for even one claim | Usually sufficient for 1-2 claims |

Key Takeaways
- Strata insurance is two layers: the master policy covers the building, your individual policy covers everything inside your unit plus the strata deductible.
- Water damage is the #1 claim type in BC. A single incident can trigger a $25,000-$50,000 deductible that may be assigned to the originating unit's owner.
- Loss assessment coverage on your individual policy is essential — it pays the strata deductible if a claim originates in your unit. Expect $30-$60 per year for $50,000-$100,000 coverage.
- BC premiums spiked 50-300% from 2019 to 2023 and have stabilized but not returned to pre-crisis levels. Building age, claims history, and construction type are the biggest premium drivers.
- Always request the Form B certificate ($35), master policy summary, claims history, and deductible schedule before buying any strata-titled multiplex unit.
- Small stratas (2-4 units) pay more per unit for insurance, have fewer insurer options, and face greater per-owner exposure when claims occur.
- BC law requires stratas to disclose all insurance details to owners and prospective buyers. The strata cannot legally withhold this information.
- Get a quote for your individual unit policy before your subject removal date — premium costs vary significantly based on the building's claims history.
Frequently Asked Questions
What does the strata master insurance policy cover?
The master policy covers the building envelope (roof, exterior walls, foundation), common areas (hallways, driveways, landscaping), shared building systems (main plumbing, electrical, HVAC trunk lines), and the strata corporation's liability to third parties. It must insure to full replacement value — the cost to rebuild the entire building from the ground up.
Full replacement value is not market value. A fourplex worth $3.2 million on the market might cost $2.5 million to rebuild, or it might cost $4 million depending on construction costs at the time. The strata must get an appraisal to determine this number and update it regularly. If the building is underinsured and a total loss occurs, the shortfall comes from the owners. The master policy also typically includes common-area liability coverage — if a visitor slips on the shared walkway, the strata's policy responds. The premium for the master policy is the single biggest line item in most small strata budgets, often consuming 35-45% of total strata fees. The strata council is legally responsible for ensuring adequate coverage, and failure to maintain proper insurance can expose individual council members to personal liability.
What should my individual unit policy cover?
Your unit policy needs five core coverages: personal contents (furniture, electronics, clothing), betterments and improvements (anything you have upgraded from the original developer finishes), personal liability (someone is injured in your unit), additional living expenses (hotel and meals if you are displaced during repairs), and loss assessment coverage (to pay the strata deductible if a claim originates in your unit).
Loss assessment coverage is the most important and most overlooked piece. If a pipe bursts in your unit and causes $80,000 in building damage, the strata's master policy covers the repair — but the $25,000-$50,000 deductible may be assessed to you under the strata's bylaw. Loss assessment coverage on your individual policy pays this deductible for you. Without it, you are writing a cheque or taking out a loan. Most insurers in BC offer loss assessment coverage as a standard add-on, typically $30-$60 per year for $50,000-$100,000 in coverage. Make sure the coverage amount matches or exceeds the highest deductible on the strata's master policy. Also ensure your betterments coverage accurately reflects what you have spent on upgrades — original developer finishes are covered by the master policy, but anything you changed (countertops, flooring, built-in shelving, bathroom tile) is your responsibility to insure.
Why did BC strata insurance premiums spike so dramatically?
Between 2019 and 2023, many BC stratas saw premium increases of 50-300%. The primary driver was water damage claims — which account for the majority of all strata claims. Insurers had been underpricing risk for years, and a wave of expensive claims in aging buildings triggered aggressive re-pricing across the entire market, including new construction.
Several factors converged: older buildings with aging plumbing systems generated large claims; construction defects in some newer buildings (particularly polybutylene piping and improperly sealed building envelopes) led to costly remediation; climate change increased freeze-thaw cycles; and a small number of insurers dominate the BC strata market, so when one repriced, the others followed. The BC Financial Services Authority (BCFSA) began monitoring the market closely and publishing annual reports on strata insurance affordability. By 2024-2025, the market began stabilizing — premiums stopped their steep climb, though they have not returned to pre-2019 levels. Deductibles also stabilized in the $25,000-$50,000 range for water damage, down from the peak of $100,000+ seen in some buildings in 2021-2022. New-construction multiplexes with modern plumbing and no claims history generally get better rates, but the building's construction type (wood-frame vs concrete) and location still significantly affect pricing.
Who pays the deductible when a claim happens?
It depends on the strata's bylaws. The BC Strata Property Act allows stratas to pass a bylaw assigning the deductible to the owner of the unit where the loss originated. Most stratas have adopted this bylaw. Without it, the deductible comes from the contingency reserve fund — and if the CRF cannot cover it, a special levy is issued to all owners proportionally.
Section 158 of the SPA allows the strata to assign the insurance deductible to the owner responsible for a claim. Before November 2018 legislative changes, the assignment had to be based on 'negligence.' Now, the strata can assign the deductible regardless of fault if they have the proper bylaw in place. This means even an accidental event — a supply line that fails due to age, not negligence — can result in the unit owner bearing the full deductible. In a fourplex with a $25,000 water damage deductible, the math is brutal: the claim is covered by the master policy, but the originating unit's owner owes $25,000. If they have loss assessment coverage on their individual policy, that coverage pays. If not, it is out of pocket. If the owner cannot pay, the strata can register a lien against their title. In small stratas, these situations are especially painful because they often pit neighbour against neighbour in a building with only 2-4 units.
What affects strata insurance premiums?
Eight main factors: building age, construction type (wood-frame costs more than concrete), claims history (the single biggest factor), location, number of units, replacement value, deductible level chosen, and the plumbing/mechanical systems installed. A new fourplex with no claims history and modern PEX plumbing will get significantly better rates than a 1980s conversion with copper pipes and two prior water damage claims.
Claims history is king. A single water damage claim over $100,000 can increase premiums by 30-50% at renewal and follow the building for 5-7 years. Some insurers will not quote buildings with more than two claims in the past five years. Construction type matters because wood-frame buildings are more susceptible to water damage than concrete — water travels farther and faster through wood framing, causing more extensive damage per incident. Location matters for earthquake and flood risk, though earthquake coverage is typically separate and optional (and very expensive in Metro Vancouver). The deductible is the biggest lever available to the strata council: choosing a $50,000 deductible instead of $25,000 can reduce premiums significantly, but it shifts more risk to individual unit owners. For new multiplexes, the developer's construction quality and choice of plumbing systems directly affects long-term insurability. PEX piping, individual unit shut-off valves, and leak detection systems are all factors that insurers look at favourably.
What should I check about insurance before buying a multiplex unit?
Request the Form B Information Certificate ($35), the current master policy summary, the claims history for the past 5-7 years, the current premium and deductible schedule, and the strata's annual budget showing the insurance line item. Compare the insurance cost as a percentage of total strata fees — if it exceeds 50%, the building may have risk factors that will affect your resale value.
The Form B certificate from the strata corporation discloses the insurance policy details, deductible amounts, and recent claims. This is legally required upon request. Beyond the Form B, ask for the actual insurance policy summary (the declarations page) which shows coverage limits, deductible amounts by claim type, and any exclusions. Check whether the building has earthquake coverage — it is expensive and many small stratas opt out, which means a seismic event leaves all repair costs with the owners. Review the claims history carefully: even if current premiums look reasonable, a building with two water damage claims in the past three years is likely facing a steep renewal increase. Get a quote for your individual unit policy before your subject removal date. If the building has an unusual claims history or high deductibles, your individual policy may be more expensive than average, or certain coverages may have exclusions. Finally, ask whether the strata has a deductible assignment bylaw — and if so, verify that you can get adequate loss assessment coverage to match.
What BC legislative changes affect strata insurance?
BC has implemented several reforms since 2019: mandatory disclosure of insurance information to owners and buyers, expanded powers for the BC Financial Services Authority to monitor the strata insurance market, amendments allowing stratas to assign deductibles by bylaw (not just negligence), and requirements for brokers to provide multiple quotes. The provincial government continues to explore further reforms including potential pooled-insurance models for small stratas.
Key legislative milestones: In 2019, the BCFSA began publishing annual strata insurance market reports after the premium crisis hit. In 2020, the government amended the SPA to require clearer disclosure of deductible amounts and insurance costs to prospective buyers through Form B certificates. In 2022, additional requirements were placed on insurance brokers serving strata corporations — they must now provide quotes from multiple insurers where available and disclose their commission structure. The government has studied whether a provincial insurance pool (similar to ICBC for auto insurance) could stabilize the strata insurance market, but no legislation has been introduced as of 2026. The BCFSA's ongoing monitoring has contributed to market stabilization, as insurers are now required to justify large premium increases. For multiplex buyers, the practical takeaway is that insurance disclosure requirements are now robust — you have a legal right to complete insurance information before purchasing, and the strata cannot withhold it.
How does insurance differ for a small strata vs a large condo building?
Small stratas (2-4 units) face higher per-unit insurance costs, fewer insurer options, and greater per-owner exposure when claims happen. A $50,000 deductible split among 4 owners is $12,500 each through a special levy. The same deductible split among 100 condo owners is $500 each. Small stratas also have less negotiating power with insurers and fewer brokers willing to handle their accounts.
The economics of scale work against small stratas. A 200-unit condo tower might pay $300,000 per year for its master policy — $1,500 per unit per year, or $125 per unit per month. A fourplex might pay $8,000-$15,000 per year for its master policy — $2,000-$3,750 per unit per year, or $167-$312 per unit per month. The per-unit cost is higher because the fixed costs of underwriting, administration, and risk assessment are spread across fewer units. Additionally, fewer insurers are willing to write policies for small stratas because the premium revenue does not justify the administrative overhead. Some brokers will not take on a fourplex account because their commission (typically 10-15% of the premium) does not cover their time. This limited market means less competition and less price pressure. The risk concentration is also higher: in a 200-unit tower, a water damage claim in one unit is statistically normal. In a fourplex, that same claim can consume the entire CRF and trigger a special levy for every owner.
