For business owners preparing a leased commercial space for opening day.

Tenant improvement is where a business idea meets the real condition of a leased space. The lease may say the unit is available. The floor plan may look simple. The opening date may feel close. But before construction can move smoothly, the owner needs to understand what the unit can support, what the landlord requires, and what the city may need to review.
For a store, restaurant, office, showroom, clinic, learning centre, warehouse office or service-based business, tenant improvement is not only interior renovation. It is the process of turning an existing commercial unit into a working business space.
The strongest tenant improvement projects usually start before the lease is fully locked in or before the design is too detailed. Early planning gives the owner a clearer picture of cost, timing, approval risk and construction scope.
What tenant improvement means in a commercial space
Tenant improvement, often called TI, usually refers to work done inside a leased commercial unit so the space can serve a specific tenant’s business. The work may be simple, such as new finishes, lighting and partitions. It may also be more involved, especially when plumbing, electrical capacity, mechanical systems, equipment, washrooms, kitchens, fire safety, accessibility or change of use are part of the project.
A tenant improvement plan should connect three things: the business model, the existing site condition and the approval path. If one of those is ignored, the project can become expensive very quickly.
For example, a restaurant unit may need kitchen equipment, service counters, seating, ventilation, cleaning access and durable surfaces to work together. An office may need meeting rooms, staff work areas, reception, lighting and acoustic privacy. A showroom needs product display, visitor flow and enough support space for staff. A warehouse office needs practical circulation between operations, storage and administration.
Start before the lease is treated as final
Many tenant improvement problems begin with the lease. A unit can look suitable during a walkthrough, but the details behind the walls, above the ceiling or inside the landlord’s criteria can change the project.
Before committing to a space, owners should understand what work is allowed, what must be approved by the landlord, whether drawings are required, what hours construction can happen, who is responsible for base building systems, and whether the existing services match the business plan.
This is especially important for food service, medical or personal service spaces, heavy equipment, exterior signage, new washrooms, sprinkler changes or any layout that affects exiting and occupancy.
- Ask for the landlord’s tenant improvement manual or design criteria.
- Review whether the existing plumbing, electrical, HVAC and fire safety systems support the business.
- Clarify what drawings, insurance, deposits and approvals the landlord expects.
- Check whether the proposed business use matches the unit and building conditions.

Site review comes before a fixed design
A good layout should be based on the site, not only on an inspiration image. The team needs to look at ceiling height, existing partitions, slab conditions, electrical panels, plumbing locations, floor drains, grease interceptor needs, mechanical routes, fire alarm devices, sprinkler coverage, exits, storefront conditions and any signs of previous unpermitted work.
These conditions affect design and budget. Moving a wall is different from moving plumbing. Adding a millwork feature is different from changing electrical capacity. A new service counter may look simple, but it can involve power, lighting, POS locations, equipment clearances and staff movement.
When the site is reviewed early, the owner can choose between design options with a better understanding of cost and schedule.
Drawings, permits and approvals should be planned together
Tenant improvement requirements vary by city, building type and scope. Some projects may move through a simpler review path, while others need a more complete building permit package and separate trade permits. Vancouver, Burnaby, Richmond and other Lower Mainland cities each have their own application requirements, forms and review processes.
Business owners do not need to become permit specialists, but they do need a team that can identify what needs to be clarified early. Drawings are not only for construction. They help the landlord, city reviewers, trades and the construction team understand the same scope.
For many projects, permit planning may involve architectural drawings, code review, mechanical or electrical coordination, plumbing information, fire safety considerations and final inspections. Food service projects often need extra coordination because kitchen equipment, exhaust, plumbing, electrical load and health-related requirements can affect the layout.

Budget should be built around scope, not only square footage
Square footage can help frame an early conversation, but it does not tell the whole story. Two units with the same size can require completely different budgets.
The biggest cost drivers usually come from existing condition, mechanical and electrical work, plumbing, fire safety changes, custom millwork, equipment, flooring, lighting, storefront work, landlord standards, permit requirements and the opening schedule.
A tenant improvement budget is strongest when the owner understands what is essential for opening and what can be phased, simplified or adjusted. Not every detail has to be expensive, but the important work has to be coordinated in the right order.
Long-lead items can control the timeline
Tenant improvement schedules are often affected by items that need to be selected, ordered or approved early. Custom millwork, specialty lighting, kitchen equipment, flooring, glass, signage, mechanical components and permit responses can all shape the opening timeline.
The schedule should leave room for design decisions, landlord comments, city review, trade coordination, inspections, deficiencies and final cleaning. A schedule that only counts construction days may look shorter, but it does not reflect the full project.
Owners can protect the timeline by confirming equipment lists, key finishes, budget priorities and landlord requirements before construction begins.

Construction handover is easier when expectations are clear
A tenant improvement project does not end when the main construction work looks complete. The final stage often includes inspections, touch-ups, cleaning, signage coordination, equipment connection, staff access, keys, owner walkthroughs and final deficiency items.
A clear handover helps the owner move from construction mode into business mode. It also helps the team close out small issues before the opening date becomes stressful.
The best handovers are not accidental. They come from a project that has been coordinated from the beginning: scope, drawings, approvals, materials, trades, inspections and day-to-day communication.

What business owners should prepare before starting tenant improvement
- The lease status and landlord contact or property manager information.
- The landlord’s tenant improvement manual, design criteria or construction rules.
- The unit address, existing floor plan, site photos and any previous drawings.
- Business type, daily operations, staff count, customer flow and storage needs.
- Equipment list, especially for restaurants, clinics, grooming stores, showrooms and industrial spaces.
- Target opening date and any lease-related deadlines.
- Budget range, must-have items and areas where the scope can be adjusted.
- Known concerns about plumbing, electrical, HVAC, sprinklers, signage, washrooms or permits.
A better start for tenant improvement
Tenant improvement is easier to manage when the design, budget, approval path and construction plan are discussed together. That does not remove every surprise, but it helps business owners make decisions before those decisions become expensive.
For owners planning tenant improvement in Vancouver, Richmond, Burnaby, Coquitlam, Langley or across the Lower Mainland, the first step is not only choosing finishes. It is understanding the space, the business, the landlord requirements and the path to opening.

FAQ
What should I check before signing a lease for a tenant improvement project?
Before signing, review whether the unit can support the intended business use, required utilities, occupancy, signage, washrooms, equipment, accessibility and landlord criteria. A lease can look attractive, but the existing condition may create renovation cost or approval issues.
What does landlord approval usually involve?
Landlord approval may involve layout drawings, finish notes, contractor insurance, construction schedule, work-hour rules, building access, protection of common areas, signage review and coordination with base-building systems such as HVAC, sprinklers and electrical service.
What is the difference between a tenant improvement allowance and the renovation budget?
A tenant improvement allowance is a contribution or credit from the landlord under the lease. It may help offset part of the build-out, but it does not automatically cover the full renovation budget, permits, equipment, furniture, signage or owner-selected upgrades.
What can delay a tenant improvement handover?
Common delays include late landlord comments, permit questions, missing existing drawings, undecided equipment, long-lead materials, changes to mechanical or electrical scope, inspection timing, incomplete deficiencies and late furniture or signage coordination.
Can tenant improvement work start before every finish is selected?
Some early work may be possible once drawings, approvals and core scope are clear, but key decisions should not be left too late. Flooring, lighting, millwork, equipment, plumbing fixtures and specialty finishes can affect ordering, rough-ins and inspection timing.
