Can You Tear Down an Older Cottage and Build New? It's Not Always That Simple

Have you ever driven past an older cottage and thought, "I'd love to buy that, tear it down, and build my dream cottage."

It sounds straightforward—but when it comes to waterfront properties, it rarely is.

One of the biggest misconceptions buyers have is assuming that because a cottage already exists on a property, they can simply replace it with a larger, newer one. In reality, there are several factors that can affect what you're allowed to build.

1. Today's Rules May Be Different Than When the Cottage Was Built

Many waterfront cottages were built decades ago, long before current zoning bylaws and shoreline regulations existed.

That means an older cottage may sit much closer to the water than today's bylaws would allow.

If the existing structure qualifies as legally non-conforming (often called "grandfathered"), you may have options to rebuild—but those options aren't automatic and need to be confirmed with the municipality.

2. Waterfront Setbacks Matter

Most municipalities have minimum setbacks from the shoreline for new construction.

If you completely remove an older cottage, you may be required to meet today's setback requirements unless the municipality confirms that rebuilding in the existing location is permitted.

This can dramatically change where a new cottage can be built.

3. Environmental Protection Areas Can Affect Your Plans

Many waterfront properties include environmentally protected areas.

Depending on the property, there may be restrictions on:

• Building locations
• Site grading
• Tree removal
• Shoreline alterations
• Vegetation removal

These rules exist to help protect water quality, wildlife habitat, and shoreline stability.

4. Bigger Isn't Always Better

Even if rebuilding is permitted, there may still be limits on:

• Building height
• Lot coverage
• Building footprint
• Distance from property lines
• Distance from neighbouring properties

If you want to build larger than what's permitted, additional planning approvals—such as a Minor Variance—may be required.

5. Don't Forget About Septic Systems

Many cottages are on private septic systems.

A larger cottage or additional bedrooms may require:

• A new septic design
• Septic approval
• A larger septic system

This can affect both your design and your budget.

6. Every Property Is Different

Even two cottages on the same lake can have completely different development opportunities.

Factors such as zoning, lot size, shoreline conditions, environmental features, existing buildings, and municipal policies all play a role.

That's why it's important not to assume that what worked for one property will work for another.

Before You Buy a Waterfront "Tear Down"

Before making an offer, consider asking:

✔ What is the property's zoning?

✔ Is the existing cottage legally non-conforming?

✔ Can a replacement cottage be built in the same location?

✔ Are there shoreline or environmental restrictions?

✔ Can the existing septic system support a new build?

✔ Will a survey be required?

✔ Should a pre-consultation with the municipality be completed before purchasing?

Buying an older waterfront cottage with plans to rebuild can be a fantastic opportunity—but only if you understand what's possible before you purchase.

A quick conversation with the municipality and a review of the property's zoning can save you significant time, money, and disappointment later on.
