If you own or manage an older property, you may have noticed that insurance costs are often higher compared to newer buildings. At first glance, this might seem surprising — mainly since older homes or commercial spaces don’t always sell for as much on the open market. The reason comes down to a key distinction: insurance is based on replacement cost, not market value. Replacement cost refers to the actual expense required to repair or rebuild your property using materials and workmanship of similar quality.

Recently, insurance advisor Trevor Elliott shared a striking example on LinkedIn. A photo compared lumber from 1918 with lumber from 2018. The 1918 wood had more than 60 growth rings, making it denser, stronger, more resistant to insects, and slower to burn. That type of old-growth lumber is no longer available at scale today. Replacing it requires premium-grade materials or specialized craftsmanship, both of which are more expensive.

Reasons Older Buildings are More Expensive to Insure

The example of old-growth lumber illustrates how materials in older properties can be stronger, rarer, and more expensive to replace today. But that’s just one piece of the puzzle. Several other factors also make older buildings more costly to insure and rebuild — and insurers take them all into account:

1. Age and Compliance Issues

Buildings constructed before the 1960s often contain outdated systems and materials that no longer meet today’s building codes. Knob-and-tube wiring, galvanized plumbing, and aging roofs can all pose safety concerns and increase the chance of a claim. Insurers know these risks make a property more vulnerable to fire, flooding, or structural failure — and they price policies accordingly. On top of that, bringing an older building up to modern safety standards after a loss can add thousands of dollars to the replacement cost.

2. Unique and Hard-to-Replace Materials

Older buildings were often constructed with materials that aren’t standard in today’s market — think plaster walls, heavy timber beams, slate roofing, or detailed stone masonry. These materials were built to last but are now expensive to source or may require custom fabrication. Even something as simple as matching historic windows or trim can significantly increase the cost of repairs, which is why replacement cost insurance is higher.

3. Specialized Labour and Craftsmanship

Replicating the quality of older properties requires specialized trades and expertise. Restoring heritage features, such as stained glass windows, hand-carved woodwork, or intricate tiling, requires hiring artisans with specialized expertise. Their work preserves the building’s character but comes with a higher price tag than general contracting. This need for specialized labour directly affects both insurance premiums and actual replacement costs after a claim.

A recent study by Deloitte found that up to 25% of Canadian small businesses are underinsured or lack commercial insurance coverage altogether.

4. Building Code Compliance During Repairs

Insurance doesn’t just cover a rebuild “as it was.” When damage occurs, insurers must ensure the property meets current building codes for fire safety, accessibility, energy efficiency, and more. For an older structure, this might mean replacing outdated electrical systems, reinforcing foundations, or upgrading insulation and HVAC. These improvements are essential but can add significant costs to any repair or replacement project, which is why code compliance is a substantial factor in premium pricing.

5. Higher Risk of Claims

Insurers look at the likelihood of a claim when setting premiums. Unfortunately, older buildings tend to carry higher risks: aging plumbing is more prone to leaks and water damage, older electrical wiring is a fire hazard, and worn roofing is vulnerable to storms. These risks mean claims are more likely, and that risk is reflected in the higher cost of insuring an older building.

6. Replacement Cost vs. Market Value

One of the biggest misconceptions property owners face is confusing market value with replacement cost. Market value is what someone would pay for your property today. Replacement cost is what it would take to rebuild it with materials and workmanship of similar quality. With older properties, replacement cost often far exceeds market value — especially when rare materials or specialized trades are required. This gap explains why insurance for older buildings can feel disproportionately expensive.

Business Property Insurance Considerations for Older Buildings

Running a business comes with many responsibilities, and protecting your physical assets should be one of your top priorities. Whether you operate a retail store, own a commercial building, or work from a home office, Business Property Insurance (also called Commercial Property Insurance) is essential for protecting your physical property and contents from unforeseen risks. For business owners, insuring older buildings, however, requires more care. Commercial property insurance protects physical assets like buildings, equipment, and inventory from perils such as fire, theft, vandalism, and accidental water damage.

What Does Business Property Insurance Cover?

Coverage varies by provider and policy, but standard protections include damage or loss due to:

Tips for Property Owners of Older Buildings

1. Get a Replacement Cost Appraisal

Please work with your insurance broker or a professional appraiser to make sure that your policy reflects the actual cost of rebuilding your property. Too often, older buildings are underinsured because owners rely on market value instead of replacement cost. An updated appraisal helps you avoid being left short in the event of a significant loss.

2. Update Critical Systems

Modernizing your plumbing, electrical, and HVAC systems doesn’t just improve safety — it can also reduce the risk of costly claims. For example, replacing galvanized pipes before they fail can save you from a significant flood, while upgrading old wiring lowers the risk of fire. Some insurers even reward proactive updates with lower premiums.

3. Keep Up with Maintenance

Ongoing upkeep is essential for older properties. Regular roof inspections, foundation checks, and routine servicing of heating and cooling systems can prevent minor issues from turning into expensive claims. Demonstrating good maintenance habits can also make your property more attractive to insurers.

4. Ask About Bylaw or Ordinance Coverage

If your older property is damaged, you may be required to rebuild it to current building codes — even if that means making extensive upgrades. Bylaw or ordinance coverage helps cover these additional costs, which aren’t always included in a standard policy. Without this coverage, owners can face significant out-of-pocket expenses after a loss.

Business Interruption Insurance (BI)

Business Interruption Insurance is designed to help you recover lost income and ongoing expenses while your business is temporarily closed. If you do need to temporarily shut down or suspend your company due to renovations or repairs, BI is an invaluable coverage to have. Most insurance providers offer a form of BI insurance that covers your revenue until your business returns to normal levels, matching revenue levels before whatever unforeseen event caused the sudden loss in the first place. However, sometimes business owners forget to protect themselves against the unexpected.

Insuring Older Buildings: Final Takeaway

Older buildings come with character, history, and craftsmanship that modern construction rarely matches. However, with those benefits come added costs and complexity when it comes to insurance and replacement. As Trevor Elliott pointed out, accurate replacement cost analysis is critical. Whether you own an older home or a commercial property, working with your insurance representative ensures you have the right coverage to protect your property — and your peace of mind.
