Sign 1: Occupancy Density Has Drifted Far Below Lease Commitments
Every lease is underwritten against an assumed density — a ratio of people to square footage that made the economics work at signing. When headcount contracts, remote-work policies tighten occupancy, or a business unit relocates, that ratio deteriorates. If your average occupied square footage per person has climbed well above your original planning assumption, the space is now priced for a larger team than exists.
The practical test is straightforward: pull your current headcount against the total rentable square footage under lease for each location. A ratio above one hundred and fifty square feet per person in a dense urban office market is a flag worth examining. A ratio above two hundred and fifty in a building you signed for open-plan collaboration deserves immediate scrutiny.
What makes this sign particularly costly is that base rent is only one layer of the problem. Operating expense pass-throughs, property tax escalations, and utility burdens are also sized against total square footage, not occupied square footage. Every underutilized square foot carries a proportional share of those charges even if no one sits in it.
Addressing this sign starts with a current-state occupancy model, floor by floor. Compare the resulting density map to the lease commitment term and determine whether the divergence is structural — likely to persist — or cyclical. That distinction drives whether a sublet strategy, lease restructure, or simple space consolidation is the right response.
Sign 2: Effective Rent Has Never Been Recalculated Since Signing
Base rent is the number on the lease. Effective rent is the number that actually describes the economics — it accounts for free rent periods, tenant improvement allowances, lease incentives, and the time value of money over the full term. Many occupier finance teams calculate effective rent at lease execution and then never return to it.
The trouble is that effective rent changes meaning over the life of a lease. Once a free rent period has expired, the annual cash burden rises. Once a TI allowance has been fully amortized into landlord economics, the effective rent per square foot as experienced by the tenant is no longer softened by that incentive. A lease that looked competitive in year one can look materially above market by year five if the market has softened.
Comparing that NPV to current market alternatives on a per-square-foot basis gives the real picture.
Landlords are aware of remaining term, and so should tenants be.
Sign 3: Critical Lease Dates Are Being Managed in a Spreadsheet
A lease contains multiple dates that carry real financial consequences: option exercise windows, termination notice periods, renewal notification deadlines, and rent review trigger dates. Missing any of these by even a few days can eliminate negotiating leverage or lock the tenant into an unwanted term at above-market rates.
Portfolio teams that track these dates in a spreadsheet face a concentration risk — one person owns the file, version control is inconsistent, and the relationship between the date and the underlying lease economics is not visible in the same view. The organizational cost of that brittleness shows up only when a date is missed, by which point the financial consequence has already materialized.
The discipline required here is named ownership of every critical date, linked to the relevant lease clause, with enough lead time before the action deadline to run a proper market analysis and negotiate. A six-month notice window is useless if the team only becomes aware of it with eight weeks to go.
That shift alone often generates more value than any single lease transaction.
Sign 4: Lease Economics Have Never Been Compared Against a Purchase or Build Scenario
The lease-versus-own decision is often treated as a one-time capital allocation question answered at inception. For most corporate occupiers, leasing is the default and the comparison is never formally revisited. But as a lease approaches renewal or expiration, the economic environment may have changed enough that a purchase or build-to-suit scenario deserves a structured analysis.
The comparison requires more than a simple rent-versus-mortgage payment calculation. It should model the opportunity cost of capital committed to a purchase, the balance-sheet treatment under current accounting standards, the flexibility value of a lease term versus the illiquidity of ownership, and the residual value assumptions embedded in a build-to-suit structure. Without all of those layers, the comparison is incomplete.
Occupier teams that have not run this analysis since their last major lease cycle are making an implicit decision to stay in their current structure without the evidence to justify it. Market conditions — particularly in periods when office valuations have moved significantly — can make ownership economics look very different from five years prior.
The right time to run this analysis is well before the lease expiration, when the full range of options is still open. Running it inside a negotiating deadline, with only weeks to respond, eliminates the option value of the purchase path before it is even evaluated.
Sign 5: You Have More Locations Than the Business Actually Needs
Portfolio rationalization is one of the most politically charged exercises in corporate real estate, which is why it tends to happen reactively — after a restructuring — rather than proactively. The financial case for rationalization, however, is ongoing. Every location carries fixed overhead: rent, operating expenses, facilities management, IT infrastructure, insurance, and compliance obligations.
The test is whether each location serves a clearly articulated business purpose that could not be served by a different configuration. A regional office that primarily hosts meetings which could be held in client space, a co-working membership, or a hotel room is a fixed cost attached to a variable need. A support function that has moved to remote-first still anchored to a signed lease is a similar mismatch.
That scoring model surfaces candidates for consolidation, downsizing, or exit without requiring an organization-wide restructuring mandate.
The output of a rationalization exercise is not always a reduction in total footprint. Sometimes it reveals that the footprint is in the wrong cities, not that it is simply too large. Redirecting occupancy cost from low-utilization markets to high-demand markets can improve the business case for real estate even when total square footage stays constant.
Sign 6: Sublease Market Risk Has Not Been Priced Into Occupancy Decisions
Every lease that extends beyond the visible planning horizon carries implied sublease risk. If the business contracts and the tenant needs to exit before lease expiration, the ability to sublease that space — and at what rent — determines the financial exposure. Most occupier teams do not formally model this risk at lease signing and do not revisit it at midterm.
Sublease market conditions vary enormously by submarket, building class, floor size, and term remaining. A large block of space in a market where landlords are actively incentivizing direct deals will be very difficult to sublease at anywhere near the contractual rent. A well-positioned, turn-key floor in a tight market may sublease at or above the in-place rent. Neither assumption should be applied generically.
The discipline here is to model sublease recovery assumptions as a scenario within the lease NPV calculation at execution. That gives the occupier a probability-weighted view of the total downside if the space is vacated, which directly informs how much rent concession to demand from the landlord as a hedge against that risk.
They have already established the recovery expectation and negotiated accordingly.
Sign 7: The Space Program Has Not Been Validated Against Actual Workflow
Office space is designed for a workflow that existed at a moment in time. When business processes change — a team moves from individual task work to collaborative project work, or from in-person client meetings to video-based client service — the space program that made sense originally can become misaligned with what the team actually does. That misalignment is invisible on the rent invoice but visible in how people use the space.
Validating a space program means comparing the design intent — how many collaboration rooms, focus spaces, amenity areas, and workstations were planned — against observed usage patterns.
A space program that is systematically over-designed for meeting rooms but under-designed for focus work does not necessarily require a new lease. It may require a fit-out reconfiguration. But without the validation exercise, the team is spending on a space configuration that does not match the work, and the cost of that mismatch compounds over time as productivity and satisfaction are affected.
They can present to the landlord a documented case for a smaller footprint rather than simply asking for a rent reduction.
Sign 8: Lease Data Is Distributed Across Disconnected Systems
The most persistently underestimated source of portfolio cost is not a single bad lease decision — it is the friction of managing a portfolio whose data lives in disconnected places. Lease abstracts are in one system, financial models are in spreadsheets, critical dates are in a shared calendar, and the broker who negotiated the deal holds the relationship context in a personal CRM.

How Lease Economics Connects All Eight Signs
Looking across the eight signs, a common thread runs through each one: a gap between the economics as captured in the lease document and the economics as experienced by the business on an ongoing basis. That gap widens whenever a review cycle is skipped, a critical date passes without analysis, or a data disconnect prevents a full picture from forming.
Lease economics is not a one-time underwriting event. The rent, the operating expenses, the escalation schedule, the remaining term, and the current market alternative all change continuously. The portfolio that looked well-priced at signing looks different after two years of market movement. The team that revisits the economics on a regular cycle does not wait for a crisis to discover the divergence.
The return on that discipline tends to be asymmetric: the downside of missing a bad sign is large, and the upside of catching it early is larger still.
The Role of the Adviser in Identifying These Signs
Corporate occupiers rarely have the bandwidth to run all eight of these diagnostics simultaneously. The team managing a lease portfolio while also supporting active transactions, facilities requests, and strategic planning has finite time. This is where the tenant representation or corporate advisory relationship pays dividends beyond the transaction.
The most useful adviser brings current market context alongside portfolio awareness. Without that market context, the occupier can identify that density has drifted but cannot determine whether the current rent is five percent above market or twenty-five percent above market. That difference determines the strategy, and the right advisory relationship ensures the data needed to make that determination is always current.
The best advisory relationships on occupier portfolios are structured around a continuous intelligence cycle rather than a transaction-by-transaction engagement model.
Building a Diagnostic Rhythm Across the Portfolio
The practical application of the eight signs is not a one-time audit — it is a rhythm.
Without a consistent scoring matrix for rationalization, the exercise produces political debate rather than analytical clarity.
When leadership changes, when a new adviser takes over a relationship, or when a business unit requests a new location, the historical data is already assembled. The team does not repeat the same orientation exercise each time a new project begins.
Each completed review cycle produces a documented snapshot that the next cycle can build on, giving the team a durable record of how the portfolio has evolved and where the economics have shifted.
From Signs to Strategy
Recognizing the 8 Signs an Office Footprint Is Costing More Than It Should is only the first half of the discipline. The second half is converting each recognized sign into a defined response — a negotiation, a restructure, a sublet, a reconfiguration, or a rationalization — with a timeline, an owner, and a financial target.
Strategy at the portfolio level means holding multiple responses in sequence and balance. A new site selection may make an existing renewal decision less urgent.
The discipline of moving from sign recognition to strategic response — consistently, across a full portfolio, on a defined cadence — is what separates a high-performing real estate function from one that is perpetually reacting to the consequences of signs it missed too late.
