Before You Sign a Commercial Lease: Check the Zoning and Permit Requirements First

ByBNW Staff

Finding the right commercial space can feel like the hardest part of opening or expanding a business.

The location looks right.

The rent fits the budget.

The floor plan appears workable.

The landlord is ready to move forward.

But there is one important question that should be answered before the lease is finalized:

Can the space legally and practically be used for what the business intends to do?

For restaurants, medical clinics, retail stores, offices, fitness facilities, daycares, automotive businesses and many other commercial uses, zoning and building-permit requirements can have a significant impact on whether a location actually works.

Signing a lease before investigating those requirements can expose a business to unexpected construction costs, approval delays and, in some situations, a space that cannot be used as originally planned.

A Good Location Is Not Automatically an Approved Location

A commercial property can look perfect without being ready for a particular business.

The previous tenant may have operated a completely different type of business.

A former clothing store might appear suitable for a restaurant.

An office might seem easy to convert into a medical clinic.

A warehouse might appear appropriate for a fitness facility or showroom.

But each change can introduce different zoning, building-code and municipal requirements.

The key question is not simply whether the physical space is large enough.

It is whether the proposed use is permitted and whether the building can satisfy the requirements associated with that use.

This is where early due diligence becomes extremely important.

Companies such as iPermit work with property owners, tenants, contractors and developers to identify building-permit, zoning, drawing and engineering requirements before significant construction commitments are made.

Start by Confirming the Proposed Use

One of the first steps should be clearly defining exactly what the business will do inside the property.

A vague description such as “retail,” “office” or “restaurant” may not provide enough information to properly assess the requirements.

For example, a restaurant could involve:

  • commercial cooking equipment;

  • exhaust and ventilation systems;

  • grease-management requirements;

  • plumbing changes;

  • additional washrooms;

  • accessibility considerations;

  • fire-protection requirements; and

  • changes to occupant load.

Similarly, a medical or dental clinic may require different plumbing, mechanical, accessibility and interior-layout considerations than a traditional office.

Even businesses that appear similar can have different requirements depending on the activities taking place inside the building.

The more clearly the proposed operation is defined, the easier it becomes to identify the correct approval path.

Zoning Should Be Reviewed Before Detailed Design

It is tempting to hire a designer immediately and begin developing the perfect floor plan.

But detailed design should not get too far ahead of zoning review.

Zoning rules can affect what uses are permitted on a property and may also influence parking, loading, building form and other site-specific requirements.

If the proposed business or construction project does not comply with the applicable zoning rules, the project may need to be modified or may require an additional municipal approval process.

Depending on the situation, this could involve:

  • a zoning review;

  • a minor variance;

  • Committee of Adjustment;

  • a zoning by-law amendment;

  • site plan approval; or

  • another municipal process.

Reviewing the applicable zoning and approval services in Toronto before committing to detailed design can help property owners and tenants better understand which municipal path may apply to their project.

A zoning review does not automatically mean that a project will face difficulties.

Its purpose is to identify those issues early enough that the project team still has options.

Understand Whether the Renovation Needs a Building Permit

Once zoning and the proposed use have been considered, the next question is whether the planned construction work requires a building permit.

Commercial renovations can vary dramatically in scope.

Some projects may focus largely on cosmetic improvements.

Others may involve:

  • new walls or partitions;

  • plumbing changes;

  • HVAC modifications;

  • new washrooms;

  • structural alterations;

  • door or exit changes;

  • fire separations;

  • commercial kitchen installations; or

  • changes in occupancy or use.

These types of modifications may trigger building-permit and technical-drawing requirements.

The City of Toronto’s requirements for non-residential interior alterations provide information on the forms, drawings and supporting documents that may be required when altering an existing commercial building.

Understanding this before construction pricing begins can make a major difference to the accuracy of the project budget.

The Existing Building Matters

Commercial leasing decisions are sometimes made based almost entirely on location and visible appearance.

But existing building conditions can affect renovation costs just as much as the proposed design.

Before committing to major improvements, project teams may need to investigate:

  • existing structural conditions;

  • HVAC capacity;

  • electrical service;

  • plumbing locations;

  • fire-protection systems;

  • existing washrooms;

  • accessible entrances;

  • exits;

  • ceiling heights; and

  • previous construction or renovations.

Older commercial properties can be particularly unpredictable.

Available drawings may not reflect current conditions, and previous tenants may have made changes over the years.

A site investigation can help identify these issues before they become expensive surprises during construction.

Do Not Assume the Previous Tenant’s Approval Transfers to the New Business

One of the most common misunderstandings in commercial leasing is assuming that because another company previously operated in the space, the new business should be able to open without significant approvals.

That is not always the case.

The previous tenant may have had a different use.

The new tenant may be proposing more occupants.

Different equipment may be installed.

The interior layout may be changing.

Additional plumbing or ventilation may be needed.

The new operation may also fall under a different municipal licensing or zoning category.

The safest approach is to evaluate the proposed business based on what the new tenant intends to do rather than relying solely on the history of the property.

Build Permit and Approval Time Into the Lease Negotiation

Permit planning is not only a design issue.

It can also be a lease-negotiation issue.

A commercial tenant may begin paying rent before construction is finished and before the business is generating revenue.

If the approval process takes longer than expected, those carrying costs can become significant.

Before signing the lease, tenants should understand the expected timeline for:

  • design;

  • zoning review;

  • permit drawings;

  • permit submission;

  • municipal review;

  • construction;

  • inspections; and

  • final occupancy or business opening.

This information can help when negotiating important lease terms such as:

  • possession date;

  • fixturing period;

  • rent-free construction period;

  • tenant-improvement allowance; and

  • target opening date.

A few additional weeks of approval time may not sound significant during lease negotiations, but they can be very expensive once monthly rent, staffing and financing costs begin.

Make Sure the Construction Budget Includes Professional Services

Another mistake is budgeting only for the contractor.

A commercial renovation may require professional services before construction can begin.

Depending on the project, those services could include:

  • architectural or design drawings;

  • structural engineering;

  • mechanical design;

  • plumbing design;

  • electrical design;

  • zoning review;

  • permit preparation; and

  • municipal application coordination.

The exact requirements vary from project to project.

A small office alteration may require relatively limited documentation, while a restaurant, medical facility or significant change of use could involve several professional disciplines.

Identifying those services early helps create a more realistic overall project budget.

Watch for Structural Changes

Commercial tenants frequently want to create larger, more open spaces.

This can involve removing existing walls or creating new openings.

But the appearance of a wall does not confirm whether it is structural.

If a structural component is affected, engineering review may be required.

That review can influence:

  • beam size;

  • column locations;

  • foundations;

  • connection details;

  • construction sequencing; and

  • overall renovation cost.

Structural questions are best answered during the design stage rather than after demolition has started.

Mechanical Systems Can Affect the Entire Project

Mechanical requirements are another area that can significantly alter a commercial renovation.

Restaurants may need commercial exhaust systems.

Medical facilities may have specialized ventilation requirements.

Larger occupant loads can affect HVAC demand.

New washrooms or sinks may require substantial plumbing changes.

Mechanical equipment can also affect other parts of the building.

For example, installing rooftop equipment may require structural review.

Running new ductwork can affect ceiling heights and architectural layouts.

Adding plumbing fixtures may affect slab penetrations or underground services.

Early coordination between design and engineering disciplines can prevent one system from creating unexpected problems for another.

Consider Accessibility Before Finalizing the Layout

Accessibility requirements can influence commercial renovations in ways that are not always obvious during the initial design stage.

Door widths, washroom layouts, corridors, entrances and changes in floor level can all become important considerations.

If accessibility requirements are discovered late in the project, they can force significant layout changes.

This is another reason why a floor plan should not be treated only as an interior-design exercise.

The layout needs to work aesthetically, operationally and technically.

Keep the Landlord Involved

Commercial renovation projects usually involve more than the tenant and contractor.

The landlord may need to approve proposed work before permit drawings are finalized.

The property owner may also have building standards relating to:

  • mechanical equipment;

  • roof penetrations;

  • plumbing work;

  • signage;

  • structural modifications;

  • electrical systems; and

  • contractor access.

Some lease agreements also restrict specific types of alterations or require the tenant to use approved contractors.

Obtaining landlord requirements early can prevent the project team from designing something that later needs to be changed.

Avoid Buying Major Equipment Before the Design Is Confirmed

A business preparing to open often wants to order equipment as quickly as possible.

That is understandable, especially when products have long lead times.

But purchasing equipment before the design and technical requirements are sufficiently understood can create problems.

A commercial appliance may require a different electrical connection.

Mechanical equipment may require additional ventilation.

A large unit may affect structural loading.

Plumbing fixtures may need to move after the permit drawings are coordinated.

Whenever possible, major equipment specifications should be coordinated with the design team before final orders are placed.

Due Diligence Can Be Cheaper Than Redesign

Professional reviews, drawings and permit planning represent an upfront cost.

But discovering a major problem after a lease has been signed can cost much more.

Imagine signing a multi-year lease and then discovering that:

  • the proposed business use requires additional zoning approval;

  • the HVAC system needs major upgrades;

  • a planned wall removal requires significant structural work;

  • washrooms need to be redesigned;

  • the project requires more extensive permit drawings than anticipated; or

  • the target opening date is unrealistic.

These issues may still be solvable.

The problem is that the tenant now has far less flexibility.

Before the lease is signed, the business can negotiate, redesign the concept or potentially choose another property.

After the lease is signed, those options become much more limited.

Ask the Right Questions Before Committing

Before finalizing a commercial lease involving renovations, tenants and property owners should try to answer several basic questions:

Is the proposed business use permitted at the property?

Will additional zoning or planning approvals be required?

What construction work is proposed?

Does that work require a building permit?

Which drawings and engineering disciplines will be needed?

Are there existing-building conditions that could affect the renovation?

What landlord approvals are required?

How long should the design, permit and construction process realistically take?

Does the project budget include professional fees as well as construction costs?

If these questions can be answered before the lease is finalized, the project begins with significantly more certainty.

Plan the Approval Path Before You Plan the Opening Date

A commercial lease is a major financial commitment.

The renovation that follows can be another.

For that reason, zoning and permits should not be treated as administrative details to deal with after the location has already been secured.

They are part of the feasibility of the location itself.

By checking zoning, understanding permit requirements, reviewing existing conditions and coordinating the necessary design professionals early, businesses can make better-informed leasing decisions.

The goal is not simply to obtain approvals.

It is to understand the true cost, schedule and feasibility of the project before the business becomes financially committed to the space.

That small shift in planning can prevent some of the most expensive surprises in commercial renovation.
