Change of Use Before Leasing: Occupancy, Exits and Permits

How to check whether a Vancouver commercial unit can accommodate your business before the lease leaves you paying for an unusable space.

A listing that says "retail or office" does not establish that your proposed business can open there. The previous tenant may have operated under a different approval, with fewer people, a different layout or restrictions that do not fit your plans.

Before committing, compare the last approved use with the operation you actually intend to run. A small teaching studio, a restaurant and a showroom can occupy similar-looking units while creating different planning, exit, washroom and building-service questions.

The useful outcome is a written feasibility decision: what is permitted, what must change, who can authorize that work and what remains unresolved. An attractive interior or an existing business licence is not a substitute for that review.

Key takeaways

Check municipal land use, building-code occupancy and business licensing separately.

Ask for approved records, then compare them with the measured space and your proposed operation.

Resolve exit routes and work outside the unit before accepting a renovation budget.

Three checks that are often confused

Land use: zoning and any applicable development approval determine whether the proposed activity can operate at that address, and on what conditions. A business description such as "wellness" may be too broad for staff to assess. Describe treatments, classes, equipment and operating hours.

Building occupancy: the building-code classification concerns how the space is used and its safety requirements. It is different from occupant load, which concerns the number of people the space is designed or permitted to accommodate. A planning-use change can matter even when the major building occupancy stays the same.

Licensing: the business licence and any health or other operating approvals are separate checks. Landlord consent does not replace them. Vancouver has its own Building By-law; do not apply Vancouver procedures automatically to Richmond or Burnaby. The local authority and project professional must confirm the applicable requirements.

Ask for the approved baseline, not just the leasing plan

Request the latest approved development and building permit drawings, available occupancy documentation, approved use and capacity conditions, and records of later alterations. Ask the landlord to identify the unit number and areas covered by each document. A floor plan without an approval record may be useful for measurement but does not establish authorized use.

Compare those records with a site survey: partitions, doors, stairs, mezzanines, washrooms, equipment and shared corridors. Mark anything different. A former tenant may have added rooms or blocked a route without the change appearing in the package you received.

Send municipal staff an address-specific enquiry with the existing approval, a proposed plan and a one-page operating description. Ask which land-use approval and building review are needed. Record the response and its assumptions; preliminary advice is not a permit.

Write the operating brief before asking about capacity

State the activities, usable areas, staff numbers, peak customers, class or appointment sizes, overlap between sessions, opening hours, cooking, storage and equipment. Include people waiting for the next session. "Twenty students" may mean more than twenty occupants once instructors, reception staff and waiting parents are included.

For example, imagine converting a retail unit into two teaching rooms. Before buying partitions, have the project professional check the proposed use, classification, calculated occupant load, routes from both rooms, washroom provision and ventilation. These are questions for that particular building, not proof that every teaching studio needs the same upgrades.

Ask for the accepted capacity and any operating conditions to be shown in the approval documents. A booking policy can support an approved arrangement; it does not automatically replace the required code calculation.

Seating is only part of the operating plan. Staff, waiting areas and circulation also matter when the proposed capacity is reviewed.

Trace every exit route beyond the tenant door

Walk from the most remote occupied area to the exterior or approved exit discharge. Have the reviewer assess the applicable exit count, travel distance, route arrangement, clear widths, door operation and separation. A front door plus a rear door does not, by itself, prove that two compliant exits exist.

Check what the rear door leads to. A route through another tenant, a locked loading area or a corridor that the landlord plans to alter needs resolution. Photograph the route and identify every door, access restriction and area outside your control.

If an acceptable route depends on someone else's space, resolve permission and the physical work before treating the unit as feasible. Ask who controls the route during operating hours and who pays for required changes. Do not assume a lease sketch creates an approved right of exit.

Separate work inside the unit from building-wide constraints

The review may identify accessibility, washroom, fire-separation, sprinkler, alarm or ventilation work. The scope depends on the building, proposed use, alterations and applicable existing-building provisions. A change of use does not automatically mean rebuilding the entire property to new-building standards.

Sort the findings into three lists: tenant work, landlord or common-property work, and unresolved investigations. A washroom redesign within the unit is a different leasing risk from an entrance alteration, shared corridor change or service connection requiring permission outside it.

For each item, record the required work, approving party, permission needed, cost basis and schedule dependency. Where the solution is unconfirmed, price an investigation or defined allowance rather than presenting a fixed total as settled.

A service-space layout needs to account for workstations, waiting customers and access between rooms, not only the number of bookings.

Turn the findings into a lease decision

Use a short decision sheet. For each issue, show the evidence, proposed solution, responsible party, cost exposure and date by which it must be resolved. The decision should be one of three: proceed on the documented basis, proceed only if named conditions are satisfied, or reject the unit for this operation.

In the teaching-space example, a feasible internal layout does not settle an unavailable shared exit. Obtain a reviewed alternative and landlord agreement before moving that issue out of the unresolved column. If the required work cannot be approved or funded, a cheaper rent does not make the unit workable.

Ask your leasing lawyer and broker how to address approval conditions, access for investigations, landlord work, deadlines and the consequences of refusal. A contractor can estimate a defined scope; the lease must deal with who carries the risk if the permission never arrives.

Our commercial renovation team guide explains how to assign the professional review and construction responsibilities. For Vancouver properties, use the City's Zoning and Development By-law as an official starting point, then confirm the address-specific position with staff.

Frequently asked questions

If the old and new businesses have the same major occupancy classification, can I skip a change-of-use review?

No automatic exemption follows from that alone. Planning-use definitions, approval conditions, occupant load and proposed alterations may still change. Give the municipality a precise operating description and existing records, and ask which approvals apply even if the building-code classification appears unchanged.

What should I do if the landlord cannot produce the old approved drawings?

Ask about a municipal records search and arrange access for a measured survey and professional review. Record which parts of the approved baseline remain unknown. Have your leasing adviser address time, access and approval risk before you make an unconditional commitment; a new survey records what exists, not whether it was approved.

Can reducing the number of seats or appointments avoid an expensive exit upgrade?

Possibly, if a lower-capacity proposal is assessed and accepted under the applicable rules. It is not enough to remove chairs or promise fewer bookings. Have the reviewer confirm the load calculation, layout, exit requirements and enforceable operating conditions, then judge whether the permitted capacity still supports the business.

Bring the address and the operating plan

Y&Y Construction can help organize site information, coordinate the appropriate design professionals and develop a construction scope around the review findings. Bring the address, available approval records, proposed activities and target capacity so the first discussion can focus on what will make that specific unit workable.
