Mass timber construction promises faster build times for greener construction, creating living spaces that will make their residents feel more connected to nature. However, for condo buyers, there’s a catch: while mass timber buildings are environmentally friendly and architecturally impressive, they’re also relatively new to the market. This article delves into the nuances of living in a mass timber building and how this may impact your condo insurance rates.

Insurance in Mass Timber Buildings At a Glance

  • Because mass timber construction is fairly new and its risks are not well-documented yet, different insurers have varying comfort levels with mass timber construction.
  • Water damage remains the most significant risk factor affecting insurance pricing for mass timber buildings, and this could potentially impact both master policies and individual unit coverage if water damage affects multiple units.
  • Canada’s National Building Code (NBC) currently allows encapsulated mass timber buildings up to 12 storeys, but some provinces plan to allow even taller structures. Ontario intends to amend its Building Code to allow structures up to 18 storeys high.

What Is Mass Timber?

Mass timber is a category of engineered wood products created by bonding solid wood layers together to form large structural components like columns, panels, and beams for construction.

This material has become popular because it’s renewable and stores carbon, helping offset emissions from other materials in a building, such as steel and concrete. Prefabricated mass timber components also allow faster, quieter onsite construction, and their relatively high strength compared to weight allows them to be used even for high-rise buildings.

However, mass timber buildings are susceptible to moisture damage and pest damage from wood-boring insects. The supply chain and industry standards for mass timber are also still fairly new, affecting pricing, design consistency, and availability.

Why This Matters to Condo Buyers

While mass timber buildings meet the same fire and structural safety standards as traditional concrete and steel buildings, insurance companies see them very differently. The reason is simple: because it’s a relatively new material, there’s almost no historical claims data related to mass timber to work with.

For condo buyers, this uncertainty creates two main concerns. First, your condo corporation’s master insurance policy (covering the building structure and common areas) will likely cost significantly more than in a traditional concrete building. Second, your personal condo insurance might also be affected, though the impact here is less predictable.

How This Affects Your Premiums and Deductibles

When it comes to the master policy, your condominium corporation’s insurance costs are likely to be higher for a mass timber building because of hesitation from insurers to cover this riskier construction type. These increased costs get passed down to unit owners through higher monthly maintenance fees.

While some insurers may charge higher premiums on your personal condo insurance if they find out your unit is in a mass timber building, others might not. This is largely because personal condo insurance primarily covers interior improvements and your belongings instead of the building’s structure itself.

How Living in Mass Timber Condos Affects Your Insurance

What to Ask Before Buying a Mass Timber Condo

Thinking of getting a condo in a mass timber building? Before you make this crucial decision, ask your insurer and condo corporation these questions:

About the Building’s Master Insurance:

  • What is the annual cost of the master insurance policy, and how does it compare to similar concrete buildings?
  • How much of the master policy cost is built into monthly maintenance fees?
  • Has the condo corporation experienced any insurance-related challenges or claim denials?

About Your Personal Coverage:

  • Will my personal condo insurance be affected by the building’s construction type?
  • Are there any specific coverage limitations or exclusions related to mass timber construction?
  • How would a major building incident (like water damage from fire suppression) affect my personal coverage?

About Future Costs:

  • How might insurance costs change as the building ages and more claims data becomes available?
  • What happens if the building can’t renew its master policy with current insurers?
  • Are there any special assessments planned or anticipated for insurance-related costs?

About Building Specifications:

  • What fire suppression and detection systems are in place beyond code requirements?
  • How is the building designed to manage water damage risks?
  • What warranties or guarantees does the developer provide regarding insurance costs?

Key Advice from MyChoice

  • If you’re facing higher premiums due to the building’s construction type, a higher deductible can help offset some of the increased costs.
  • Consider saving money by bundling your condo insurance with other policies, such as auto insurance. This strategy will be especially valuable if your mass timber condo pushes your insurance costs higher than expected.
  • Before purchasing a unit, ask for documentation about the building’s insurance arrangements. Understanding these costs upfront helps you budget accurately and avoid surprises down the road.
