In Toronto and across the Greater Toronto Area, mixed-use buildings—those combining residential and commercial components—are increasingly common. Whether it’s a storefront with apartments above or a multi-storey structure housing retail, office, and residential units, these properties present unique challenges when it comes to insurance.

A critical but often overlooked piece of risk management is the insurance appraisal. Done correctly, it ensures that the property is insured to value and that the owner is not overpaying or dangerously underinsured. But when done incorrectly—or skipped entirely—insurance appraisals can lead to thousands of dollars in premium overpayments or even more devastating losses if a claim arises and the coverage falls short.

Understanding the nuances of insurance valuation for mixed-use properties is not optional—it’s essential. Yet many building owners make the same costly mistakes, often due to misinformation or working with the wrong professionals.

Why Insurance Appraisals Matter for Mixed-Use Buildings

An insurance appraisal is not a market value estimate. Instead, it calculates the replacement cost new of the building—what it would cost to rebuild the structure as it stands today, using modern materials and construction methods, excluding land value.

For mixed-use buildings, this process is inherently more complex. The presence of commercial space on the ground floor (e.g., retail, restaurant, office) and residential units above means varying construction standards, building codes, and mechanical systems. An accurate insurance valuation must account for each use distinctly, while still treating the property as a cohesive whole.

When building owners rely on general market estimates, outdated figures, or assume their insurer’s valuation is sufficient, they’re often left either underinsured or significantly overpaying.

Mistake #1: Using Market Value Instead of Replacement Cost

The most common—and most damaging—mistake is confusing market value with replacement cost. Market value reflects what someone would pay for the property, including land value, future income potential, and location. But insurance companies only pay for the cost to rebuild the structure itself.

Using market value as a proxy for insurance can lead to serious underinsurance. In the event of a fire or structural loss, the owner may receive a payout that falls short of actual rebuilding costs—especially when specialized commercial elements are involved.

Mistake #2: Failing to Differentiate Between Residential and Commercial Components

In mixed-use buildings, the cost to rebuild commercial space is often significantly higher than residential. Commercial storefronts typically require more extensive HVAC, fire protection, storefront glazing, structural reinforcement, and accessibility features. An accurate insurance appraiser will break down these distinctions in the appraisal, ensuring each component is properly assessed.

Many generic insurance appraisal companies miss this nuance, treating the entire property as a single construction type or averaging replacement costs across the building. This oversimplification often leads to inaccurate premiums or disputed payouts during claims.

Mistake #3: Not Updating the Appraisal Regularly

Construction costs change. Code requirements evolve. Building renovations alter the replacement profile. If your insurance appraisal is more than three years old, there’s a high probability it no longer reflects the current rebuild value of your property.

This outdated valuation becomes a liability in two ways: you could be overpaying in premiums based on inflated rebuild costs, or you could be underinsured due to rising material and labour expenses.

IPS strongly recommends updating your insurance valuation every three to five years—or immediately after significant renovations, tenant changes, or zoning shifts that affect structural use.

Mistake #4: Choosing the Wrong Appraisal Firm

Not all appraisal companies specialize in insurance. Even fewer specialize in insurance valuation services for complex property types like mixed-use buildings. Many providers offer broad valuation services but lack experience in the construction intricacies, code implications, and cost breakdowns required for accurate insurance appraisals.

Working with a generalist appraiser or a firm without deep knowledge of both residential and commercial construction exposes property owners to inaccuracies. It’s essential to choose an insurance appraisal company that understands your asset class—and treats it as more than just a line item on a form.

Mistake #5: Overlooking Bylaw Coverage and Code Upgrades

When a building is damaged, it must be rebuilt to meet current codes—not the ones in place when it was originally constructed. That includes accessibility (AODA), fire safety upgrades, and zoning adjustments. If your insurance appraisal doesn’t account for these potential costs, your policy may not cover them. This is especially crucial in older Toronto mixed-use buildings where non-compliance with modern code can lead to large out-of-pocket costs post-claim.

A thorough appraisal from an experienced firm will factor in these “soft costs” and recommend appropriate bylaw endorsements to discuss with your insurance broker.
