Change of Use: What Triggers It

Moving from one type of business to another can change the rules that apply to the space, even when the walls stay in place.

Change of Use: What Triggers It

What counts as a change of use

A change of use occurs when the new activity falls into a different occupancy category or has different demands. An office becoming a restaurant, or a store becoming a daycare, are typical examples.

Smaller shifts, such as adding a commercial kitchen, may also trigger review.

Always check the current occupancy of the space. A previous tenant may have operated under a different category than the one on record.

What may be required

The authority may require upgrades to fire separations, exits, sprinkler coverage, washroom counts, ventilation and accessibility. Zoning may also have to allow the new use.

Each requirement can be a significant cost item.

Sound separation, grease handling and exhaust are other items that can be triggered by food and assembly uses.

How to check first

Before leasing, ask the municipality what is needed for your use. A contractor and designer can review the existing building against the new use and flag likely upgrades.

Our engineers, electricians and mechanical crew look at power, ventilation and plumbing capacity at the same time, so the whole picture is clear.

Plan the budget and timing

Include design fees, permit time and construction for the upgrades. A change of use usually means a longer approval process than a simple interior fit-out.

If the landlord must agree, factor in their review time.

Negotiate with the facts

If upgrades are substantial, they may justify a landlord contribution, a longer rent-free period or a different space.

A change of use is often easier to manage when we are involved before the lease, since we can tell you what the building will need.

Questions we hear

How do I find out if my use is a change?

Ask the municipality, and have your designer review the building. Do it before leasing.

Does a change of use delay opening?

It can, because approvals and upgrades take extra time. Plan for it early.
