Office Renovation Costs, Budgeting and lease planning Guide
Make Faster, Smarter Real Estate Decisions
Your office space is your place of business. It is where you work, collaborate, and often receive and serve your clients. More than just a workplace, it is a strategic asset that supports your ability to deliver value through professional and efficient service.
Business owners, developers, and executive teams in corporate and institutional organizations frequently face the decision of whether to initiate a commercial renovation, a fit-out, or a tenant improvement project. The challenge is making these high-stakes capital decisions with clarity, long before budgets are locked and mistakes become irreversible.
Once you understand the context, business needs, and potential benefits of a renovation project, the worst mistake is to move too quickly into hiring contractors without first defining conceptual options and obtaining the cost intelligence required to make confident decisions.
Criticality of lease timing and office renovations
Many organizations treat office renovations as standalone projects and lease renewals as purely legal exercises. In reality, these decisions are financially inseparable. Renovating without aligning lease terms is one of the most common—and costly—mistakes in corporate real estate.
When planning a strategic move or considering a long-term lease for a new office space, decisions must be made well in advance, typically 12 months or more.
In practice, commercial tenants usually operate under long-term leases and must decide whether to renew 12 to 18 months before lease expiry.
New leased spaces, usually get transformed through major office fit-outs before occupation.
The points above simply implies that, office fit-out and renovation decisions must be anticipated and integrated into lease planning to avoid time pressure, cost escalation, and loss of strategic options. Office fit-outs are capital expenditures, not operating costs. These investments must be amortized over the useful life of the space, which is typically 5 to 10 years. Waiting too long can reduce your bargaining power, limit your options for a new space, and impact your strategic planning.
Key questions to consider early:
Are you planning early enough to maintain leverage with the landlord?
Is your lease term long enough to justify the office fit-out investment?
Are major office renovation costs included in your capital plan as a long-term investment?
Are fit-out and renovation decisions made early enough in the lease renewal or relocation process?
Do you understand the total fit-out costs before occupancy, alongside rent and incentives?
Office Renovation Costs and Capital Planning
Major office renovations are significant capital investments that require careful planning and alignment with your lease strategy. Without this alignment, even well-intentioned projects can face financial and operational challenges.
Before committing to a renovation or lease renewal, it is critical to validate your capital plan alongside your lease strategy. The rule of thumb is that the lease term should be long enough to recover the investment, since office renovations are considered capital expenses, not operating costs.
A structured preconstruction and cost-planning process ensures that all decisions are informed, realistic, and financially sound. Most capital project failures do not happen on site—they originate before a single contract is signed. Early planning mitigates risks, clarifies budgets, and improves the likelihood of project success.
This approach is especially relevant for major office renovations or full gut renovations, rather than minor cosmetic updates such as painting or carpet replacement.
Office Renovation Budget: Rules of Thumb
At this stage, you want a rough order-of-magnitude budget for your office renovation project. Two key questions guide early planning:
What is the area of the lease space or the potential space to be renovated?
What rule-of-thumb budget, unit cost per square foot, can be used for screening purposes?
If you have a strong relationship with a contractor under a master service agreement, you may be able to rely on cost performance reports or benchmarks from past projects. This is often the most reliable reference for capital planning.
Otherwise, external data can be used. Industry reports published annually by major commercial real estate firms, the big four, provide useful benchmarks. Fit-out costs vary with project scope, space quality, and location.
2025 Benchmarks (JLL Data):
Average office fit-out cost across Canada: $278 per sq.ft (includes hard costs, soft costs, FF&E, data, and IT)
Greater Toronto Area: $300 per sq.ft
As a first screening tool, using $300 per sq.ft is reasonable. Remember, depending on the office layout and its efficiency, the space quality and technical its complexity, your specific cost may vary by plus or minus 12–20%.
Conceptual Budget for Commercial Renovation
For most real estate executives, the focus is not on looking to deliver cheaper projects, but on making better decisions. Before committing to a major renovation, you should clarify your functional needs. Examples include:
Office rooms: standard offices, director and executive offices
Workstations: cubicles, open workstations, hot-desking stations
Collaborative spaces: meeting rooms, conference rooms, training rooms
Amenities: kitchens, dining areas, lobbies, lounges
Support spaces: printing rooms, washrooms, storage, server rooms, electrical rooms
Traditionally, these functional needs are provided to an architect or interior designer, who develops a layout at a cost. A cost consultant may then produce an estimate, also at a cost. The process requires multiple meetings and weeks to receive a preliminary, conceptual budget.
