A stacking plan is a visual, floor-by-floor diagram of a building, typically a multi-tenant office, that maps which tenant occupies each suite or floor, the square footage each one leases, the date each lease expires, and where space is vacant. It often layers in rent and use type as well, and it is usually color-coded so the building's occupancy and upcoming rollover can be read at a glance.
What a stacking plan means
A stacking plan takes the dry rows of a rent roll and turns them into a picture of the building. Imagine the structure drawn as a stack of horizontal bars, one for each floor, from the ground level up to the roof. Within each floor, blocks represent the suites, and every block is labeled with the tenant, the square footage, and the lease expiration. A glance down the stack tells you who occupies the building, how the space is divided, and where the gaps are.
The color coding is what makes the diagram so useful. A common scheme shades occupied space one color, vacant space another, and leases expiring within the next year or two in a third. Some teams add shading for tenants in holdover, suites under a letter of intent, or space the owner has reserved for expansion. The result is a single image that communicates the state of the building faster than any table can.
It is worth being precise about what a stacking plan is and is not. It is not a floor plan in the architectural sense, since it does not show the exact shape of walls, corridors, or elevator cores. Instead it is a schematic, a logical representation of how leased area and tenancy stack up through the building. That abstraction is the point. By stripping away architectural detail, the stacking plan keeps attention on the information that drives leasing and asset decisions: who is where, for how long, and at what size.
Why a stacking plan matters in commercial real estate
Occupancy and lease timing sit at the center of a building's value, and a stacking plan is the clearest way to see both at once. An owner or asset manager looking at the diagram can immediately judge how full the building is, how that occupancy is distributed, and how exposed the asset is to leases rolling over in the near term. Those are the questions that shape budgets, business plans, and the price a buyer or lender is willing to support.
The diagram is especially powerful for managing rollover. When several large leases expire within the same eighteen-month window, the building faces a concentration of risk: a wave of space could come back at once, and re-leasing it all on a similar timeline strains both the budget and the leasing team. A stacking plan makes that concentration visible long before it arrives, so the team can start renewal conversations early, stagger expirations where a lease structure allows, and plan capital for the suites most likely to turn.
It also drives leasing strategy on the upside. A prospect that needs a large contiguous block is a common and valuable opportunity, and a stacking plan reveals where vacant or soon-to-expire suites sit next to or above one another. Spotting that two adjacent half-floors expire in the same quarter can turn what looked like ordinary vacancy into a full-floor offering for a marquee tenant. The diagram is just as useful in the other direction, helping a team identify smaller suites to market to growing tenants already in the building.
Finally, a stacking plan is a communication tool. Brokers use it to pitch available space to prospects, showing exactly where a suite sits and what surrounds it. Owners share it with lenders and investors to convey the building's profile and the durability of its income. Internally, it gives everyone from the leasing director to the property manager a common reference point, so conversations about the building start from the same shared picture rather than competing spreadsheets.
Key takeaways
- A stacking plan is a visual, floor-by-floor diagram that shows tenants, leased areas, lease expirations, and vacancy across a building.
- It makes upcoming rollover visible early, so teams can plan renewals, stagger expirations, and assemble contiguous space for larger tenants.
- Built from the rent roll and lease data, it serves owners, asset managers, leasing teams, lenders, and brokers as one shared picture of the asset.
What a stacking plan shows
A well-built stacking plan layers several pieces of information onto each floor. The exact mix varies by owner and purpose, but most diagrams include the following elements.
Floors and suites
The backbone of the diagram is the building drawn floor by floor, with each floor subdivided into the suites or blocks of space that make up the tenancy. A single tenant might occupy a full floor, several floors, or a portion of one, and the diagram reflects those divisions so the physical structure of the tenancy is clear.
Tenant and leased area
Each occupied block carries the tenant's name and the square footage it leases. Square footage is often the rentable area, which is what the tenant pays on, and seeing it on the diagram lets a reader gauge the relative size of each tenancy at a glance.
Lease expiration and status
Expiration dates are the element that turns a stacking plan from a snapshot into a planning tool. Color coding typically flags leases expiring soon in a distinct shade, and status markers can show holdover, renewal in progress, or a signed letter of intent. This is the layer that supports rollover and retention planning.
Vacancy and rent
Vacant suites are shaded clearly so available space stands out, and many stacking plans add the rent or rent per square foot for each tenancy. Layering rent onto the diagram connects the physical picture to the building's income, which is useful when weighing renewal terms against the rents a vacant suite could command.
How teams use a stacking plan
Because the stacking plan condenses so much lease information into one view, several roles lean on it for different decisions throughout the year. The common threads are occupancy, timing, and opportunity.
- Rollover and expiration planning. Asset managers scan the diagram to see which leases expire in the coming years and whether those expirations cluster, then time renewal outreach and capital planning accordingly.
- Identifying contiguous space. Leasing teams use the stack to find vacant or expiring suites that sit together, assembling larger contiguous blocks to market to tenants that need room to grow.
- Tenant retention. By surfacing upcoming expirations early, the plan prompts proactive conversations with valuable tenants well before a lease ends, protecting occupancy and income.
- Repositioning and capital planning. Owners considering renovations or a change in tenant mix use the diagram to map where space will free up and how a repositioning could be phased.
- Marketing and communication. Brokers present the stacking plan to prospects to show exactly where available suites sit, and owners share it with lenders and investors to convey the building's profile.
- Acquisition and underwriting. When evaluating a purchase, a buyer reads the stacking plan alongside the rent roll to understand occupancy, rollover exposure, and the upside in below-market or soon-to-expire space.
What each element represents
The value of a stacking plan comes from reading its elements together. The table below summarizes the common pieces of information a diagram carries and what each one tells the people relying on it.
| Element | What it represents |
|---|---|
| Floor and suite | The physical position of each tenancy in the building, showing how space stacks from the ground up. |
| Tenant name | Who occupies each block, making the tenant mix and any concentration in one occupier visible. |
| Leased square footage | The size of each tenancy, usually rentable area, so the relative scale of each lease is clear. |
| Lease expiration date | When each lease ends, the basis for rollover, renewal, and capital planning. |
| Vacancy | Space available to lease today, shaded to stand out so opportunities are easy to spot. |
| Rent or rent per square foot | The income tied to each tenancy, connecting the physical picture to the building's financial profile. |
Best practices
The most useful stacking plans share a few qualities. The first is accuracy, because the diagram is only as good as the lease data behind it. A stacking plan should be built directly from the rent roll and the underlying lease documents, so the square footage, expiration dates, and rent it shows match the legal reality of the building. A diagram drawn from stale or guessed numbers can lead a team toward the wrong conclusions about vacancy or rollover.
The second is currency. Leases sign, renew, expand, and expire continuously, and a stacking plan loses value the moment it falls behind those events. Teams that rely on the diagram keep it updated as part of their leasing routine rather than rebuilding it once a quarter from scratch. The closer the plan stays to live lease data, the more confidently a team can act on it.
A third practice is consistency in how the diagram is coded. A clear, documented legend, where each color and marker means the same thing every time, lets anyone read the plan without a verbal explanation. Owners with several buildings benefit from applying the same scheme across the whole portfolio, so a manager moving between assets reads each stacking plan the same way.
Finally, strong stacking plans are built with their audience in mind. A version prepared for a lender might emphasize weighted average lease term and income durability, while one a broker hands to a prospect highlights available and soon-to-expire suites and the potential to assemble contiguous space. Tailoring the emphasis without changing the underlying data keeps the diagram honest and persuasive for each purpose.
Frequently asked questions
What is a stacking plan in commercial real estate?
A stacking plan is a visual, floor-by-floor diagram of a building that shows which tenant occupies each suite or floor, how much square footage each one leases, when those leases expire, and where space is vacant. It is usually color-coded so an owner, asset manager, or broker can read the building's occupancy at a glance and plan leasing decisions from it.
What is the difference between a stacking plan and a rent roll?
A rent roll is a tabular list of every lease in a property, with details such as tenant name, square footage, rent, and expiration date. A stacking plan presents much of that same lease information visually, mapped onto the physical floors of the building, so the spatial relationships between tenants, vacancy, and expirations become obvious. The two work together: the rent roll is the source data, and the stacking plan is the picture drawn from it.
How do you create a stacking plan?
A stacking plan is built from accurate lease data, usually drawn from the rent roll and the underlying lease documents. You map each floor of the building, place each tenant in its suite, record the leased square footage and expiration date, mark vacant space, and apply color coding to show status such as occupied, expiring soon, or vacant. Keeping it tied to the lease data is what allows it to stay current as leases sign, renew, and expire.
Why is a stacking plan important for leasing?
A stacking plan shows where vacancy sits today, which leases roll in the coming years, and where contiguous space could be assembled for a larger tenant. That makes it the working tool a leasing team uses to time renewal conversations, position available suites, plan for upcoming rollover, and tell a clear story about the building to prospects and lenders.
